Instructions

Step-by-Step Instructions

🔪 Prep Time: 10 minutes

🍳 Cook Time: 35 minutes

🍽️ Total Time: 45 minutes

🧑‍🍳 Servings: 6

 

  1. Preheat the oven to 375°F (190°C). Grease an 8×8 or 9×9 baking dish.

  2. In a large bowl, whisk together eggs, milk, salt, and pepper until fully combined.

  3. Stir in the sourdough discard until the mixture is smooth.

  4. Add cheese, cooked bacon or sausage, and vegetables into the bowl. Mix until evenly distributed.

  5. Pour the mixture into the prepared baking dish.

  6. Top with extra cheese if desired.

  7. Bake for 30–35 minutes, or until the center is set and the top is golden brown.

  8. Let cool for 5 minutes before slicing and serving.

Notes

  • Room Temperature Ingredients: Let your discard and eggs come to room temp for a fluffier texture.

  • Don’t Overmix: Stir just until combined to avoid a dense bake.

  • Use What You Have: Leftover roasted veggies or cheese scraps work perfectly.

 

  • Bake Until Set: Insert a knife in the center—if it comes out clean, it’s ready.
