What you’ll love about this Sourdough Apple Dutch Baby:
Ingredients Overview
🥚 Large eggs – Provide structure, lift, and richness to the Dutch baby. Eggs help it puff up beautifully in the oven. My favorite eggs are organic pasture raised eggs as they have such great nutrients.
🥛 Whole milk – Adds moisture and creaminess. Whole milk gives the best flavor and texture thanks to its fat content.
🌾 All-purpose flour – Gives the batter body and helps it set into a light, pancake-like texture when baked. Organic un-bleached all-purpose flour is my go-to as it isn’t sprayed with pesticides and then bleached.
🍞 Sourdough starter (active or discard) – Adds a subtle rise. Great way to use up discard and sneak in gut-friendly fermentation benefits. New to sourdough? – START HERE!
🍦 Vanilla extract – Enhances the overall flavor and adds warmth and sweetness.
🧂 Salt – Balances the sweetness and brings out the flavors of the other ingredients.
🍏 Large apples, peeled, cored & thinly sliced – The star fruit! Brings natural sweetness, texture, and seasonal flavor. Do yourself a favor and get this apple corer and peeler. Worth the $20!
🧈 Butter – Used to sauté the apples and prevent sticking. Adds richness and depth.
🍯 Brown sugar – Brings a caramelized sweetness and pairs beautifully with apples and cinnamon.
🥥 Coconut sugar – A less refined sweetener that adds a hint of molasses flavor and balances the brown sugar.
🌰 Cinnamon – Adds cozy, warm spice that enhances the apple flavor and makes this Dutch baby so good!

How to Make a Sourdough Apple Dutch Baby
- Preheat the oven to 400°F (200°C).
- Make the batter:
- In a medium mixing bowl, whisk together the eggs, whole milk, sourdough starter (active or discard), flour, vanilla extract, and salt until smooth and well combined. Set aside while you prepare the apples. This allows the flour to hydrate slightly and the batter to rest.
- Prepare the apple filling:
- In a 10-inch cast iron skillet, melt the butter over medium heat. Add the sliced apples, brown sugar, coconut sugar, and cinnamon. Cook, stirring occasionally, for about 5–7 minutes, or until the apples are soft and caramelized.
- Add the batter:
- Once the apples are tender and the sugars have melted into a syrupy glaze, gently pour the prepared batter over the apples in the skillet. Do not stir.
- Bake:
- Carefully transfer the skillet to the preheated oven and bake for 15–20 minutes, or until the Dutch baby is puffed and golden around the edges. The center should be just set.
- Serve:
- Remove from the oven and let it cool slightly. Serve warm, topped with powdered sugar, or a drizzle of maple syrup.

Storage & Reheating
Storage: Let the Dutch baby cool completely before storing. Transfer leftovers to an airtight container and refrigerate for up to 3 days. For best texture, store slices in a single layer or with parchment between layers to prevent sticking.
Reheating: To reheat, place individual slices in a 300°F (150°C) oven for about 8–10 minutes or until warmed through. You can also reheat in a skillet over medium-low heat for a few minutes per side.
Avoid the microwave if possible—it can make the texture rubbery.
Tip: While best enjoyed fresh from the oven, leftovers still taste delicious and make a quick, satisfying breakfast the next day!
