• 1 cup diced bell peppers: Bell peppers bring a sweet crunch and vibrant color to the dish.
• 1 cup diced onions: Onions add a subtle sweetness and aromatic flavor when sautéed.
• 1 teaspoon salt: A careful seasoning to bring out all the fabulous flavors.
• 1/2 teaspoon black pepper: Adds a gentle hint of spice and warmth to balance the cheese and veggies.
• 1 tablespoon olive oil: Essential for sautéing the vegetables to tender perfection without overpowering them.

How to Make Breakfast Quesadilla Casserole Recipe

Step 1: Preheat the Oven

First things first, preheat your oven to 350°F (175°C). This temperature ensures your casserole bakes evenly, with the eggs setting just right and the cheese melting into a gorgeous golden topping.

Step 2: Prepare the Egg Mixture

In a large bowl, whisk together your eggs, milk, salt, and black pepper until fully blended. This mixture will be the custard that sets your casserole into a fluffy, rich delight.

Step 3: Sauté the Veggies

Heat the olive oil in a skillet over medium heat, then toss in the diced bell peppers and onions. Cook them until they become soft and fragrant, releasing their natural sweetness, which adds amazing flavor to every bite.

Step 4: Add the Sausage

Mix the cooked and crumbled sausage into the skillet with the veggies, warming them through and allowing those savory juices to blend beautifully with the vegetables.

Step 5: Layer the Tortillas

Grease a baking dish to prevent sticking, then lay down the first layer of tortillas. These will form the base that holds all the delicious ingredients.

Step 6: Add the Sausage and Veggie Mix

Spread the sausage, pepper, and onion mixture evenly over the tortilla layer, making sure every corner is covered with this savory goodness.

Step 7: Pour the Egg Mixture

Carefully pour your egg and milk blend over the top, letting it trickle into all the nooks and crannies. This step ensures the casserole sets with a lovely custard texture.

Step 8: Sprinkle on the Cheese

Generously top off the dish with shredded cheddar cheese. This will melt into a golden, gooey topping that’s simply irresistible.

Step 9: Bake

Place the casserole in your preheated oven and bake for 30 to 35 minutes or until the eggs are fully set and the cheese is bubbly and lightly browned.

Step 10: Cool and Serve

Let your Breakfast Quesadilla Casserole Recipe cool for a few minutes before slicing. This little pause helps the casserole firm up for clean, beautiful servings ready to enjoy.
