- 1 cup Bell Peppers: Diced and colorful, they add sweetness and a beautiful pop of color.
- 1 medium Onion: Finely chopped for that deep, savory sweetness that enhances the overall flavor.

How to Make Easy One-Pot Breakfast Casserole Recipe
Step 1: Preheat and Prep
Start by preheating your oven to 350°F (175°C), so it’s ready to bake your masterpiece. This simple step ensures even cooking, giving you that perfectly golden finish.
Step 2: Sauté the Onions
Heat olive oil in a large skillet over medium heat, then add your finely chopped onions. Sauté until they turn translucent, about 3 to 4 minutes, releasing their natural sweetness and creating a rich base for the veggies.
Step 3: Add Bell Peppers
Next, toss in the diced bell peppers and cook for another 3 to 4 minutes. This step softens them while allowing their vibrant colors and mild sweetness to shine through in the casserole.
Step 4: Wilt the Spinach
Add the roughly chopped spinach to the skillet and give it a few minutes to wilt. This not only boosts the nutrition but also blends smoothly into the mixture without overpowering other flavors.
Step 5: Whisk the Eggs and Milk
In a mixing bowl, crack all 8 eggs and pour in the milk, salt, and pepper. Whisk everything together until the mixture is slightly frothy, which helps make the casserole light and airy once baked.
Step 6: Combine Veggies and Cheese
Fold the sautéed vegetables into the egg mixture, then stir in the shredded cheddar cheese. This combination ensures every bite has a rich, cheesy flavor with fresh vegetable goodness.
Step 7: Prepare to Bake
Grease a 9×13 inch baking dish to prevent sticking, then pour your casserole mixture evenly into the dish. Spreading it nicely helps the casserole bake uniformly and develop a lovely crust on top.
Step 8: Bake Until Golden
Place the dish in your preheated oven and bake for 30 to 35 minutes. Look for a gorgeous golden-brown color and test doneness by inserting a toothpick in the center—it should come out clean.
Step 9: Cool and Serve
Allow the casserole to cool for about 10 minutes. This resting time lets it set perfectly, making it easier to cut into neat squares and serve warm.

Try kale, Swiss chard, or even green peas as alternatives. They bring their own unique texture and nutrients while blending nicely with the other ingredients.
How do I make this recipe dairy-free?
Use a plant-based milk like almond or oat milk and swap the cheddar cheese for a dairy-free version. Just make sure the cheese melts well to keep the casserole creamy.
