Step-by-Step Instructions
Step 1: Preheat the Oven
-
Preheat your oven to 375°F (190°C).
-
Lightly grease a 9×13-inch baking dish with olive oil or non-stick spray.
Step 2: Prepare Vegetables
-
Wash and dice all vegetables uniformly for even cooking.
-
For zucchini or mushrooms, sauté lightly for 2–3 minutes to remove excess moisture.
-
Set aside spinach and tomatoes; they will be added raw to retain freshness.
Step 3: Mix the Egg Base
-
In a large bowl, whisk eggs with milk, garlic powder, salt, and black pepper.
-
Beat until slightly frothy to incorporate air, which makes the casserole lighter.
Step 4: Assemble the Casserole
-
Spread the vegetables evenly in the prepared dish.
-
Pour the egg mixture over the vegetables.
-
Sprinkle shredded cheese evenly on top, if using.
-
Optionally, add diced cooked chicken for protein.
Step 5: Bake
-
Bake uncovered for 30–35 minutes, or until the eggs are set in the center.
-
The top should be lightly golden and slightly puffed.
-
Allow the casserole to rest 5–10 minutes before slicing; this helps it hold together.
Step 6: Serve
-
Cut into squares and serve warm. Pair with fresh fruit or yogurt for a complete, light breakfast.
Tips for a Light and Balanced Casserole
-
Use fresh vegetables: Fresh ingredients add flavor and help keep the dish light.
-
Drain or sauté watery vegetables: Zucchini and tomatoes can release water; lightly cooking or draining helps prevent sogginess.
-
Control the cheese: Use a moderate amount or choose a light variety to maintain a lighter profile.
-
Uniform pieces: Cutting vegetables evenly ensures consistent baking and texture.
Variations to Keep It Exciting
-
Vegetarian Boost: Add black beans or chickpeas for extra protein without meat.
-
Protein Addition: Include diced cooked chicken, turkey, or firm tofu.
-
Cheese Options: Try light mozzarella or Swiss for different flavors.
-
Spice It Gently: Add a pinch of paprika or smoked paprika for warmth without heaviness.
-
Make-Ahead Friendly: Assemble the night before and bake in the morning for convenience.
Storage and Reheating
Refrigeration:
-
Store leftovers in an airtight container for up to 4 days.
-
Cover the casserole to prevent drying.
Freezing:
-
Slice into portions and wrap individually in foil or plastic wrap.
-
Freeze for up to 3 months. Thaw overnight in the refrigerator.
Reheating:
-
Oven: 350°F (175°C) for 10–15 minutes until heated through.
-
Microwave: 1–2 minutes per portion on medium power.
Common Mistakes to Avoid
-
Overcrowding the dish: Too many ingredients can prevent even cooking.

Skipping vegetable prep: Watery vegetables can make the casserole soggy.

Overmixing eggs: Can lead to a rubbery texture.
