Ingredients
Scale
Meat
- 10 to 12 ounces sausage (casing removed)
Vegetables
- 2 cloves garlic (minced)
- 3 cups fresh spinach (90g)
- 2 large bell peppers (diced)
- ½ medium yellow onion (diced)
- Salt and pepper (to taste)
Dairy & Eggs
- 12 large eggs
- ½ cup milk (120g, any type)
- ½ cup shredded cheese (56g, any flavor; divided)
Others
- Olive oil (for sautéing)
Instructions
- Prepare the Casserole Dish: Spray a 7 x 11" or 9 x 13" casserole dish with non-stick spray and set aside. If baking immediately, preheat the oven to 375ºF (191ºC).
- Cook the Sausage: In a large skillet over medium heat, brown the sausage, even if fully cooked, to enhance flavor. Once browned, spoon the sausage evenly into the prepared casserole dish and set aside.
- Sauté the Vegetables: Add a little olive oil to the skillet if needed. Sauté the minced garlic, fresh spinach, diced bell peppers, and diced yellow onion until vegetables are tender and spinach is wilted, about 6-7 minutes. Season with salt and pepper in the last minute.
- Combine Sausage and Vegetables: Remove the vegetable mixture from heat and add it to the casserole dish with the sausage. Stir roughly to evenly distribute the mixture.
- Mix Eggs and Cheese: In a medium bowl, whisk together the 12 large eggs, ½ cup milk, and ¼ cup of shredded cheese. Pour the egg mixture evenly over the sausage and vegetables in the casserole dish. Sprinkle the remaining ¼ cup of shredded cheese on top, and season again with salt and pepper.
- Bake the Casserole: If not done yet, preheat the oven to 375ºF (191ºC). Bake the casserole for approximately 45 minutes or until the edges start to brown. Allow it to cool for at least 15 minutes before serving.
- Storage and Reheating: Store leftovers in the refrigerator for up to 5 days. Reheat individual servings in the microwave as needed.
- Freezing Instructions: The casserole can be frozen unbaked for up to 2 months. Cover tightly with plastic wrap and foil. Thaw overnight in the refrigerator and bake at 350ºF (177ºC) for about 20 minutes or until heated through.
Notes
- This casserole can be baked immediately, prepared the night before, or frozen for future use.
- Feel free to customize the vegetables or cheese type based on preference.
- Using fully cooked sausage can save prep time, but browning enhances flavor.
- Allowing the casserole to cool before serving improves texture and flavor.
- For a vegetarian version, substitute sausage with plant-based alternatives and ensure cheese and milk are vegetarian-friendly.
