Today I’m showing how to make a Sourdough Skillet Dinner using discarded sourdough starter. This is a practical, delicious way to use both fridge leftovers and your sourdough discard so nothing goes to waste.
An Easy Sourdough Skillet Dinner
A Sourdough Skillet Dinner is one of the simplest, most flexible meals to prepare. Gather leftover cooked vegetables, cooked meat, or beans, sauté them in a cast-iron skillet, then top with a savory sourdough discard mixture and bake. The finished dish has a comforting, tamale-pie–style texture without the cornmeal crust.
Besides being quick and tasty, this recipe is economical and waste-conscious. Use up ingredients that might otherwise languish in the fridge and transform your sourdough discard into a flavorful topping that bakes into a golden, cheesy crust.

Sourdough Skillet Dinner

Equipment
-
10-12 inch cast iron frying pan
Ingredients
Skillet Mixture
- 2 tbsp Butter, salted or unsalted Any other fat can be substituted (ghee, olive oil, coconut oil, tallow, or lard).
- 1 large Onion, diced
- 3 cups Chopped veggies, fresh or canned
- 1 tsp Salt Reduce to 1/2 tsp if using salted butter.
- 1/2 tsp Ground black pepper
- 1/4 tsp Crushed red pepper flakes (optional)
- 2 cups Chopped cooked chicken (or other cooked meat, beans, or lentils)
Skillet Topping
- 1 tsp Herb seasoning (Italian, Herbes de Provence, etc.)
- 2 tsp Baking powder
- 1 tsp Baking soda (optional) Helps reduce the sourness of the discard if desired.
- 1 tsp Salt
- 1 1/2 cups Sourdough starter (discard)
- 3 tbsp Melted butter, cooled
- 3 large Eggs
- 1 1/2 cups Cheese, grated (any melting cheese or combination)
Instructions
Skillet Mixture
-
Preheat the oven to 400°F (200°C).
-
Melt the butter in a 10–12 inch cast-iron frying pan over medium heat. Add the diced onion and sauté until golden, a few minutes.
-
Add the chopped vegetables, salt, black pepper, and red pepper flakes (if using). Sauté until the vegetables are tender.
-
Stir in the chopped cooked chicken (or other protein) and warm through. Remove the pan from the stovetop and set it on a foil-lined baking sheet to catch any overflow when baking.
Skillet Topping
-
In a medium bowl, combine the herb seasoning, baking powder, salt, and baking soda (if using).
-
Add the sourdough starter (discard) and mix until smooth.
-
Stir in the cooled melted butter, then beat in the eggs until fully incorporated.
-
Pour the batter-like topping evenly over the skillet mixture. Sprinkle grated cheese across the top.
-
Bake at 400°F for about 25 minutes, until the topping is puffed and golden and the cheese has melted. Let rest briefly, then serve.
-
Store well-wrapped leftovers in the refrigerator for 2–3 days or freeze for up to 2 months. To reheat, warm on a baking sheet in a 325°F oven for about 20 minutes.
