Ingredients You’ll Need

Before you start cooking, gather the following ingredients:

• 12 large eggs
• 1 cup milk (dairy or non-dairy)
• 1 cup shredded cheese (cheddar, mozzarella, or your favorite)
• 1 bell pepper, diced
• 1 cup spinach, chopped
• 1 cup diced cooked ham or cooked sausage (optional)
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• Cooking spray or oil for greasing the pan

Preparing Your Ingredients

To ensure a smooth cooking experience, prep your ingredients ahead of time:

1. Begin by preheating your oven to 350°F (175°C).
2. In a large mixing bowl, crack the eggs and whisk them together with the milk, salt, pepper, garlic powder, and onion powder until well combined.
3. Chop the bell pepper and spinach into bite-sized pieces. If you’re using any meat, make sure it’s cooked and diced.
4. Grate your cheese if you haven’t done so already.

Assembling the Casserole

Once your ingredients are prepped, it’s time to assemble the casserole:

1. Lightly grease a large sheet pan (approximately 18×13 inches) with cooking spray or a thin layer of oil to prevent sticking.
2. Spread the chopped vegetables evenly across the bottom of the sheet pan.
3. If using meat, sprinkle it over the vegetables.
4. Pour the egg mixture over the vegetables and meat, ensuring even coverage.
5. Sprinkle the shredded cheese on top, distributing it evenly.

Baking the Casserole

Now that the casserole is assembled, it’s time to bake:

1. Place the sheet pan in the preheated oven.
2. Bake for 25-30 minutes, or until the eggs are set and the top is lightly golden brown.
3. Check for doneness by inserting a knife or toothpick into the center; it should come out clean.

Cooling and Storing the Casserole

Once baked, let the casserole cool for a few minutes before slicing:

1. Remove the sheet pan from the oven and allow it to cool on a wire rack for about 10 minutes.
2. Using a sharp knife, cut the casserole into squares or rectangles, depending on your preference.
3. Transfer the slices to an airtight container for storage or serve immediately.

Serving Suggestions

This sheet pan egg casserole is delicious on its own, but you can elevate your breakfast with a few serving suggestions:

Freezing and Reheating

If you plan to make this casserole in advance, freezing is a great option:

1. Once the casserole is completely cool, wrap individual portions in plastic wrap or foil.
2. Place the wrapped portions in a freezer-safe bag or container, and label with the date and contents.
3. To reheat, remove the desired portion from the freezer and let it thaw in the refrigerator overnight.
4. Reheat in the microwave for 1-2 minutes or until heated through, or place in a preheated oven at 350°F (175°C) for about 10-15 minutes.
