What Is a Healthy Egg Casserole?
A healthy egg casserole is a baked breakfast dish made with whisked eggs, vegetables, lean protein, and light cheese. It’s the perfect one-pan meal that’s satisfying, full of flavor, and ideal for feeding a crowd or prepping meals for the week.
Egg casseroles are great for busy mornings because they’re easy to customize — you can add your favorite vegetables, meats, or dairy alternatives and still end up with a balanced, nutritious dish.
Ingredients You’ll Need
Here’s a basic, wholesome version of a healthy egg casserole that you can modify to suit your taste:
-
8 large eggs
-
1 cup low-fat milk (or unsweetened almond milk)
-
1 cup chopped spinach
-
½ cup diced bell peppers
-
½ cup chopped onion
-
½ cup chopped broccoli florets
-
½ cup cherry tomatoes, halved
-
½ cup shredded cheddar or mozzarella cheese (optional)
-
¼ teaspoon salt
-
¼ teaspoon black pepper
-
½ teaspoon garlic powder
-
Olive oil or cooking spray (for greasing the dish)
Optional Add-ins: Cooked turkey sausage, mushrooms, or diced chicken breast for extra protein.
Step-by-Step Instructions
Step 1: Preheat the oven
Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish with olive oil or non-stick spray.
Step 2: Prepare the veggies
Chop all the vegetables into small, even pieces. If you’re using broccoli or mushrooms, lightly sauté them for 2–3 minutes to remove excess moisture.
Step 3: Whisk the eggs
In a large mixing bowl, whisk together eggs, milk, salt, pepper, and garlic powder until fully combined.
Step 4: Add veggies and cheese
Stir in all the chopped vegetables and shredded cheese (if using). Mix gently to combine.
Step 5: Pour and bake
Pour the egg mixture evenly into the prepared baking dish. Bake for 30–35 minutes, or until the top is golden and the center is set. A knife inserted in the center should come out clean.
Step 6: Cool and serve
Let the casserole rest for about 5 minutes before slicing. This helps it set and makes serving easier.
