INGREDIENTS
- 12 large eggs
- 1 cup milk (whole or 2% works best)
- 2 cups shredded cheese (cheddar, Monterey Jack, or a blend)
- 1 cup diced ham, cooked bacon, or breakfast sausage
- 1 medium bell pepper, diced (any color)
- 1 small onion, finely diced
- 2 cups baby spinach (optional)
- 2 tablespoons fresh chives or green onions, chopped
- 1 teaspoon garlic powder
- 1/2 teaspoon dried oregano
- Salt and pepper to taste
- 2 tablespoons butter, melted
- 1/2 cup cherry tomatoes, halved (for topping)
- Additional cheese for sprinkling on top
INSTRUCTIONS
Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish with cooking spray or butter. This ensures your egg casserole won’t stick to the dish when serving.
In a large mixing bowl, crack all 12 eggs and whisk them thoroughly until the whites and yolks are completely combined. Pour in the milk and continue whisking until the mixture is smooth.
Add the garlic powder, dried oregano, salt, and pepper, mixing well to distribute the seasonings evenly.
Heat a large skillet over medium heat and add a tablespoon of butter or oil. Add the diced onions and bell peppers, sautéing for about 3-4 minutes until they begin to soften.
If you’re using raw meat like sausage, cook it in the same skillet until fully cooked. For pre-cooked meats like ham or bacon, you can add them directly to the egg mixture.
Add the sautéed vegetables to your egg mixture, followed by the meat, spinach (if using), and 1½ cups of shredded cheese. Stir gently to combine all ingredients. Pour the entire mixture into your prepared baking dish, spreading it evenly with a spatula.
Top the casserole with the remaining cheese, halved cherry tomatoes, and a sprinkle of additional chives or green onions. Drizzle the melted butter over the top for an extra golden crust.
Bake uncovered for 35-40 minutes, or until the center is set and no longer jiggly. The top should be lightly golden and slightly puffed.
Let the casserole rest for 5-10 minutes before slicing and serving. This resting period allows the eggs to set further and makes for cleaner slices. Serve warm with toast, fresh fruit, or breakfast potatoes for a complete meal.
FAQs
Can I prepare this egg casserole the night before?
Yes! You can prepare all the ingredients and mix them together the night before. Store the mixture covered in the refrigerator overnight, then bake it in the morning.
You may need to add 5-10 minutes to the baking time if cooking directly from the refrigerator.
How long will leftovers keep in the refrigerator?
Leftover egg casserole will keep well in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 1-2 minutes or until heated through.
Can I freeze this casserole?
Yes, this egg casserole freezes well. Let it cool completely, then cut into portions and wrap them individually in plastic wrap and aluminum foil. Freeze for up to 3 months.
Thaw overnight in the refrigerator before reheating.
What substitutions can I make for dietary restrictions?
For a dairy-free version, use unsweetened almond or oat milk and dairy-free cheese. For a vegetarian option, simply omit the meat and add extra vegetables like mushrooms, zucchini, or broccoli.
For a lower-carb version, focus on adding more vegetables and reduce the milk slightly.
Why is my egg casserole watery?
Watery casseroles typically result from vegetables with high water content releasing moisture during baking. To prevent this, sauté vegetables before adding them to the egg mixture to release some of their moisture.
Also, avoid freezing raw vegetables in the casserole as they’ll release water when thawed and baked.
