Easy Crockpot Sourdough Discard Focaccia with Rosemary

This was supposed to be a simple loaf of sourdough. I had my starter fed and bubbly, my flour measured, my bench scraper ready. But somewhere between feeding my starter and realizing I had a overflowing jar of discard, I grabbed the wrong container and dumped a cup of unfed, sleepy discard into my dough. I was already running late for a work call, the kitchen was a mess, and honestly, I almost just tossed the whole sticky mess in the trash. But I didn’t. I scraped it into my crockpot out of pure desperation, sprinkled some rosemary on top because it was the only herb not wilted in my fridge, and walked away. What came out a few hours later was nothing like the plan—and better. It was soft, pillowy, and had that perfect tangy sourdough flavor, all without the stress of a hot oven or a complicated shaping process. I mean, I stood there staring at it for a solid minute, convinced it was a fluke. But I made it again the next week, and the week after that, and let me tell you—this crockpot focaccia is now the only way I use up my discard. Maybe you’ve been there, staring at a jar of discard wondering what to do with it. This recipe is your answer.

Why You’ll Love This Recipe

Let me be real with you—I’ve tested this recipe more times than I care to admit. I’ve burned focaccia in ovens, I’ve undercooked it, I’ve had it stick to every pan imaginable. This crockpot version? It’s the one that finally worked without fail. Here’s why it’s become my go-to:

• Quick & Easy: Comes together in under 10 minutes of active prep, then your slow cooker does the rest. Perfect for busy weeknights or lazy weekend afternoons.
• Simple Ingredients: No fancy grocery trips needed. You likely already have flour, olive oil, salt, and rosemary in your kitchen. And of course, that jar of sourdough discard sitting in your fridge.
• Perfect for Sourdough Discard: This is the ultimate way to use up that discard without having to feed your starter first. It’s a zero-waste win that tastes incredible.
• Crowd-Pleaser: I’ve brought this to potlucks and family dinners, and it always gets rave reviews. Kids love the soft texture, adults love the herbaceous flavor.
• Unbelievably Delicious: The texture is what gets me every time—crispy, golden edges from the crockpot’s heat, with a soft, airy interior that’s perfect for sopping up soup or olive oil.

What makes this recipe different from the rest? It’s the technique. By using the crockpot, you get a consistent, gentle heat that creates a tender crumb without the risk of a scorched bottom or a dry top. Plus, the discard adds a subtle tang that pairs beautifully with the earthy rosemary. This isn’t just another focaccia recipe—it’s my best version, born from a happy accident and perfected through trial and error.

This recipe isn’t just good—it’s the kind that makes you close your eyes after the first bite. It’s comfort food reimagined—easier, faster, but with the same soul-soothing satisfaction. Perfect for impressing guests without stress, or turning a simple Tuesday dinner into something memorable.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, and the sourdough discard is the star of the show. Here’s what you’ll need:

For the Dough

• 1 cup (240g) sourdough discard – Unfed, straight from the fridge. This is the key ingredient that gives the focaccia its signature tang and tender crumb. I prefer using my discard at room temperature for best results, but cold works too—it just takes a little longer to rise.
• 2 cups (250g) all-purpose flour – I recommend King Arthur Flour for consistent results, but any good brand works. Bread flour can also be used for a chewier texture.
• 1 teaspoon salt – Fine sea salt is best. It dissolves more evenly than kosher salt in this small amount of dough.
• 1 teaspoon instant yeast – This gives the focaccia a little extra lift, especially since the discard isn’t super active. SAF Instant Yeast is my go-to brand.
• 1 cup (240ml) warm water – About 110°F (43°C). Too hot and you’ll kill the yeast; too cold and it won’t activate. Think warm bath water.
• 2 tablespoons olive oil – For the dough. Use a good quality extra virgin olive oil for flavor. I love California Olive Ranch for its fruity notes.

For the Topping

• 2 tablespoons olive oil – For drizzling in the crockpot and over the top before baking.
• 2 tablespoons fresh rosemary, chopped – Dried rosemary works in a pinch, but fresh gives a much better flavor and aroma. (adds a woodsy, earthy note)
• Flaky sea salt – Like Maldon salt. This is for sprinkling on top right before serving. It adds a nice crunch and pop of saltiness.

Ingredient Selection Tips

For the best texture, use a discard that’s no more than a week old. Older discard can be more acidic and might affect the flavor. If your discard is very liquidy, you might need to adjust the flour slightly—add an extra tablespoon or two if the dough feels too sticky. Also, look for firm, fresh rosemary sprigs with no wilting. The oil in the leaves is what gives the focaccia that amazing aroma.

Substitution Guidance

You can easily make this gluten-free by using a 1:1 gluten-free flour blend. The texture will be a bit denser, but still delicious. For a dairy-free version, this recipe is already dairy-free! Just double-check your yeast and discard are dairy-free as well. If you don’t have rosemary, try thyme or oregano for a different herbaceous twist.

Equipment Needed

You don’t need much for this recipe, which is part of its beauty. Here’s what you’ll need:

• A 6-quart or larger slow cooker – I use a Crock-Pot brand, but any brand works. The size matters because you need enough surface area for the dough to spread out. A smaller crockpot will make a thicker focaccia, which is fine, just adjust the cooking time slightly.
• Parchment paper – This is essential for easy removal. You’ll line the bottom of your crockpot with a parchment sling so you can lift the focaccia out cleanly.
• A large mixing bowl – For mixing the dough. Any bowl works, but a wide one makes it easier to stir.
• A wooden spoon or dough whisk – For mixing. I prefer a dough whisk because it doesn’t get clogged, but a wooden spoon works fine too.
• A sharp knife or kitchen shears – For chopping the rosemary.
• A small bowl – For mixing the topping oil and rosemary.

If you don’t have a crockpot, you can bake this in a 9×13 inch baking dish at 400°F (200°C) for about 25-30 minutes. The texture will be slightly different—crispier on the bottom—but still delicious. I’ve also used a Dutch oven with the lid on for a similar effect, but the crockpot is truly the easiest method. Just make sure your crockpot has a “high” setting, as that’s what we’ll use.

Preparation Method

This method is broken down into simple steps. Trust the process, and don’t skip the resting time—it’s where the magic happens.

1. Mix the dough: In a large mixing bowl, combine the sourdough discard, all-purpose flour, salt, instant yeast, and warm water. Stir with a wooden spoon or dough whisk until a shaggy, sticky dough forms. It will look rough and lumpy—that’s okay. Don’t be tempted to add more flour; the stickiness is what gives the focaccia its airy texture.

2. Add the olive oil: Drizzle 2 tablespoons of olive oil over the dough and stir again until the oil is mostly incorporated. The dough will become smoother and slightly less sticky. Cover the bowl with plastic wrap or a damp kitchen towel and let it rest for 20 minutes. This autolyse step helps the gluten relax and makes the dough easier to handle later.

3. First rise: After the rest, perform a series of stretch and folds. Wet your hands slightly to prevent sticking, then grab one side of the dough, stretch it up, and fold it over the center. Rotate the bowl a quarter turn and repeat. Do this 4-6 times, then cover the bowl again. Let the dough rise at room temperature for 1-2 hours, or until it has doubled in size. It should look puffy and bubbly on top.

4. Prepare the crockpot: While the dough rises, line your crockpot with a large piece of parchment paper. Make sure the paper comes up the sides by at least 2 inches—this will be your sling for lifting the focaccia out later. Drizzle 1 tablespoon of olive oil into the bottom of the lined crockpot and spread it around with a pastry brush or your fingers.

5. Transfer the dough: Gently scrape the risen dough into the prepared crockpot. It will be sticky and soft, so use a rubber spatula dipped in water to help release it from the bowl. Don’t deflate the dough too much—you want to keep as many air bubbles as possible.

6. Second rise: Cover the crockpot with its lid and let the dough rise again for 30-45 minutes. It should puff up and fill the bottom of the crockpot. If it’s not spreading, gently press it out with oiled fingers.

7. Add the topping: In a small bowl, mix the remaining 1 tablespoon of olive oil with the chopped rosemary. Drizzle this mixture over the top of the dough. Use your fingers to gently press dimples into the dough, pushing the oil and rosemary into the surface. This is what gives focaccia its signature look and helps the flavors infuse.

8. Cook: Place the lid on the crockpot and cook on HIGH for 1.5 to 2 hours. The exact time depends on your crockpot. Start checking at 1.5 hours—the top should be golden brown and the edges should be crispy. The internal temperature should reach about 200°F (93°C). If the top is still pale, let it cook another 15-30 minutes. Don’t lift the lid too often, as this lets out heat and steam.

9. Finish and serve: Once cooked, turn off the crockpot and carefully lift the focaccia out using the parchment sling. Transfer it to a wire rack to cool for at least 10 minutes. Sprinkle with flaky sea salt while it’s still warm. Cut into squares or slices and serve warm or at room temperature.

Cooking Tips & Techniques

I’ve made this focaccia more times than I can count, and I’ve learned a few things the hard way. Here are my top tips for success:

• Don’t skip the parchment: I once tried to cook this directly in the crockpot without parchment. Big mistake. The bottom got stuck and I ended up with a crumbled mess. The parchment sling is your best friend for easy removal.
• Watch the heat: Every crockpot runs a little differently. If yours runs hot, check the focaccia at 1 hour 15 minutes. If it runs cool, it might take the full 2 hours. The top should be a deep golden brown, and the edges should pull away from the parchment slightly.
• Get those dimples right: Don’t be shy with your fingers when making dimples. Press all the way down to the bottom of the dough. This not only creates those iconic pockets but also helps the oil and rosemary seep into the bread.
• Room temperature discard is key: Cold discard straight from the fridge will slow down the rise. If you’re in a hurry, you can use it cold, but expect a slightly denser focaccia. I usually take my discard out 30 minutes before starting.
• My biggest failure: The first time I made this, I used too much water and ended up with a flat, gummy mess. I was so frustrated. Now I always measure my water carefully, and if the dough feels too wet, I add an extra tablespoon of flour. It’s better to have a slightly stiff dough than a soupy one.

Variations & Adaptations

This recipe is incredibly versatile. Here are some of my favorite ways to change it up:

• Herb Swap: Not a rosemary fan? Try fresh thyme, oregano, or even dried Italian seasoning. I’ve made a version with fresh dill and lemon zest that was amazing with grilled fish.
• Cheese Lover’s: Sprinkle 1/2 cup of shredded Parmesan or crumbled feta over the top before cooking. The cheese gets crispy and golden in the crockpot—it’s heavenly.
• Garlic Infusion: Add 2-3 minced garlic cloves to the olive oil and rosemary mixture. It gives the focaccia a savory punch that’s perfect for dipping in marinara.
• Everything Bagel: After dimpling, sprinkle the top with everything bagel seasoning (sesame seeds, poppy seeds, garlic flakes, onion flakes, and salt). This is my family’s favorite variation.
• Sweet Version: Omit the rosemary and salt, and instead drizzle the top with honey and sprinkle with cinnamon sugar. Cook as directed, then drizzle with a simple glaze made of powdered sugar and milk. It’s like a cinnamon roll and focaccia had a baby.

Serving & Storage Suggestions

This focaccia is best served warm, straight from the crockpot. The contrast between the crispy edges and the soft, airy center is unbeatable. I love serving it alongside a bowl of tomato soup or a hearty minestrone. It’s also fantastic as a side for pasta dishes, grilled meats, or a simple salad. For a quick appetizer, cut it into small squares and serve with a dish of olive oil and balsamic vinegar for dipping.

To store leftovers, wrap the focaccia tightly in aluminum foil or plastic wrap and keep it at room temperature for up to 2 days. Do not refrigerate—it will dry out the bread. For longer storage, slice it and freeze in a zip-top bag for up to 3 months. To reheat, pop it in a 350°F (175°C) oven for 5-10 minutes, or toast it in a skillet with a little butter. The flavors actually develop overnight, so day-old focaccia is even more flavorful. Just reheat it gently to bring back that soft texture.

This focaccia is a good source of carbohydrates for energy, and the olive oil provides healthy monounsaturated fats. The sourdough fermentation process makes the bread easier to digest and may help with blood sugar regulation. Plus, rosemary is packed with antioxidants and anti-inflammatory compounds. It’s not health food, but it’s a wholesome indulgence that fits into a balanced diet. If you’re watching your sodium, you can reduce the salt or use a salt substitute.

FAQs

Can I use active sourdough starter instead of discard?

Yes, you can! If you use active, bubbly starter, you might need to reduce the instant yeast to 1/2 teaspoon since the starter will provide more leavening. The texture will be even airier and lighter.

My focaccia came out too dense. What went wrong?

This usually happens if the dough didn’t rise enough. Make sure your yeast is fresh and your water is warm (not hot). Also, give the dough enough time to double in size during the first rise. If your kitchen is cold, let it rise in a warm spot, like near a sunny window or on top of the fridge.

Can I double this recipe?

Absolutely! Double all the ingredients and use a larger crockpot (at least 8 quarts). You may need to increase the cooking time by 20-30 minutes. Just keep an eye on the top—it should be golden brown and cooked through.

How do I get a crispy bottom on the focaccia?

The crockpot doesn’t naturally create a crispy bottom, but you can achieve it by removing the focaccia from the crockpot after cooking and placing it on a baking sheet under the broiler for 2-3 minutes. Watch it closely so it doesn’t burn.

Can I make this ahead of time?

Yes! You can prepare the dough through step 6 (the second rise in the crockpot), then cover and refrigerate it for up to 12 hours. When you’re ready to cook, let it sit at room temperature for 30 minutes, then add the topping and cook as directed. The cold ferment adds even more flavor.
