How to Make Veggie Breakfast Casserole

Making this casserole is straightforward. Follow the simple steps below, and you’ll have a delicious breakfast dish that everyone will enjoy.

Preheat your oven: Start by preheating your oven to 375°F (190°C). This ensures your casserole cooks evenly and comes out perfectly golden.
Prepare your baking dish: Spray a 9×13-inch baking dish with nonstick spray. This helps prevent the casserole from sticking, making for easy cleanup.
Cook the veggies: In a nonstick skillet, heat the olive oil over medium heat. Once hot, add the diced onions and sauté for 2-3 minutes until they soften.
Add more vegetables: Next, stir in the diced red and green bell peppers along with the sliced mushrooms. Cook this mixture for 4-5 more minutes until the vegetables are tender. Season with kosher salt and black pepper, then remove from heat and let it cool slightly.
Mix the eggs: In a large mixing bowl, whisk together the large eggs, milk, kosher salt, and black pepper until well combined. This mixture will be the base of the casserole.
Assemble the casserole: Spread the cooked vegetables evenly across the bottom of the prepared baking dish. Top them with the quartered cherry tomatoes.
Add the egg mixture: Pour the egg mixture over the vegetables in the dish, making sure to cover everything evenly.
Top with cheese: Lastly, sprinkle the shredded mozzarella cheese over the top. This will melt and create a delicious cheesy crust as it bakes.
Bake it: Place the baking dish in your preheated oven and bake for 30-35 minutes. You’ll know it’s done when the eggs are set and the edges are slightly golden.
Cool and serve: Let the casserole cool for about 5 minutes before slicing. This will make it easier to cut and serve.

Best Ways to Serve Veggie Breakfast Casserole

This Veggie Breakfast Casserole can be served hot or warm. It pairs wonderfully with a fresh fruit salad or avocado slices on the side. You might also enjoy drizzling some hot sauce or salsa over a slice for added flavor. If you have guests, consider serving it with coffee or freshly squeezed juice.

How to Store Veggie Breakfast Casserole

If you have leftovers (which is rare because it’s so tasty!), you can store them in an airtight container in the refrigerator for about 3-4 days. To reheat, simply place a slice in the microwave for a minute or two until warmed through. You can also heat individual portions in the oven for about 10-15 minutes at 350°F (175°C) for best texture.

Prep Ahead: You can chop your vegetables the night before to save time in the morning.
