- 1/2 cup crumbled feta cheese
- 1/2 cup shredded cheddar cheese
- 1/2 cup cooked and crumbled breakfast sausage (turkey or pork) or diced ham
- 1/2 cup chopped spinach (fresh or frozen and thawed, squeezed dry)
- 1/4 cup finely diced bell pepper (any color)

How to Make High Protein Egg Casserole:
This High Protein Egg Casserole is incredibly straightforward, making it a weeknight savior! Expect a prep time of about 15 minutes and a bake time of around 30-35 minutes. The result is a gloriously fluffy, deeply savory, and satisfying breakfast bake that’s a joy to prepare and even better to eat.
Step-by-Step Instructions:
- Preheat Oven and Prepare Dish: Preheat your oven to 375°F (190°C). Lightly grease an 8×8 inch baking dish or a similar-sized casserole dish with cooking spray or butter.
- Sauté Vegetables and Meat: Heat the olive oil or butter in a skillet over medium heat. Add the diced onion and bell pepper and sauté for 3-4 minutes until they begin to soften. Add the cooked and crumbled breakfast sausage or ham and cook for another 2-3 minutes, stirring occasionally, until heated through. If using fresh spinach, add it now and cook until wilted, about 1-2 minutes. If using frozen spinach, ensure it’s thawed and squeezed completely dry before adding it to the skillet.
- Prepare the Egg Mixture: In a large bowl, whisk together the dozen large eggs and 1 cup of milk until well combined. Season generously with salt and black pepper, remembering that the cheese and sausage will also add saltiness.
- Combine Ingredients: Add the sautéed vegetable and meat mixture to the egg mixture. Stir in the crumbled feta cheese and shredded cheddar cheese. Gently fold everything together until evenly distributed.
- Pour into Baking Dish: Pour the egg mixture evenly into the prepared baking dish. Ensure that the ingredients are spread out so that each serving gets a good mix of everything.
- Bake the Casserole: Place the baking dish in the preheated oven. Bake for 30-35 minutes, or until the casserole is set in the center and the top is golden brown. A knife inserted into the center should come out clean.
- Rest and Serve: Once baked, remove the High Protein Egg Casserole from the oven and let it rest for 5-10 minutes before slicing and serving. This allows the casserole to set fully, making it easier to cut and serve.
