Ingredients
Scale
Sausage and Vegetables
- 10 to 12 ounces sausage (casing removed)
- 2 cloves garlic (minced)
- 3 cups fresh spinach (90g)
- 2 large bell peppers (diced)
- ½ medium yellow onion (diced)
- Salt and pepper (to taste)
- Olive oil (as needed for sautéing)
Egg Mixture
- 12 large eggs
- ½ cup milk (120g, any type)
- ½ cup shredded cheese (56g, any flavor; divided)
Instructions
- Prepare casserole dish: Spray a 7 x 11 or 9 x 13 inch casserole dish with non-stick spray and set aside. Preheat the oven to 375ºF (191ºC) if baking immediately.
- Brown the sausage: In a large skillet over medium heat, brown the sausage until cooked through. Drain excess grease if needed. Spoon browned sausage evenly into the casserole dish.
- Sauté vegetables: Add a little olive oil to the same skillet, then sauté the garlic, spinach, bell peppers, and onion until tender and spinach is wilted, about 6 to 7 minutes. Season with salt and pepper during the last minute of cooking.
- Combine sausage and vegetables: Remove skillet from heat and transfer the cooked vegetable mixture to the casserole dish with sausage. Stir roughly to combine evenly.
- Mix eggs and cheese: In a medium bowl, whisk together the eggs, milk, and ¼ cup shredded cheese. Pour this mixture evenly over the sausage and vegetables in the casserole dish. Sprinkle the remaining ¼ cup cheese and a bit more salt and pepper on top.
- Bake the casserole: Bake uncovered at 375ºF (191ºC) for about 45 minutes or until the edges turn golden brown. Let cool for at least 15 minutes before serving.
- Optional storage: You may cover and refrigerate the casserole for up to 24 hours before baking. Leftovers can be stored refrigerated for up to 5 days and reheated in the microwave. The baked casserole can be frozen for up to 2 months.
- Freezing unbaked casserole: To freeze unbaked casserole, cover tightly with plastic wrap and foil. Thaw overnight in the refrigerator before baking as directed.
Notes

- You can bake it immediately or prepare ahead and refrigerate overnight for easy mornings.
- Freezing the casserole (baked or unbaked) is convenient for meal prep or entertaining.
- To reheat leftovers, microwave individual portions until warmed through.
