Step‑by‑Step Instructions for Southwest Tortilla Breakfast Casserole

Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). While the oven heats up, take a moment to prepare your ingredients: dice the onion and red bell pepper into 1/4-inch pieces, chop the green chiles, shred the Monterey Jack cheese, and cut the corn tortillas into strips. Having everything ready will make the assembly process much smoother!

Step 2: Cook the Sausage and Vegetables
In a large skillet over medium-high heat, heat a tablespoon of olive oil until shimmering. Add the breakfast sausage and cook for about 4-5 minutes, breaking it apart and browning it evenly. Next, add the diced onion and red bell pepper, cooking for another 1-2 minutes until they soften. Stir in the green chiles, seasoning with salt and black pepper to taste, then remove from heat and set aside.

Step 3: Whisk the Egg Mixture
In a mixing bowl, crack open the six room-temperature eggs and whisk them together with 1/2 cup of whole milk, 1 teaspoon of paprika, and 1/2 teaspoon of red pepper flakes. Keep whisking until the mixture is frothy and fully combined, then sprinkle in a pinch of salt. This creamy custard will bind all the layers of your Southwest Tortilla Breakfast Casserole beautifully.

Step 4: Layer the Casserole
Take a lightly oiled 9×13-inch baking dish and start layering. Begin with a layer of tortilla strips, followed by half of the cooked sausage mixture, and then sprinkle some of the shredded cheese on top. Pour a portion of the egg custard over this layer. Repeat the layering process once more, finishing with a final layer of tortilla strips topped with the remaining egg custard.

Step 5: Bake the Casserole
Place the layered casserole in your preheated oven and bake it for about 35 minutes. Keep an eye on it during the last few minutes, noting that the center should be slightly jiggly, and the top should turn a lovely golden brown. This will ensure that your breakfast casserole is cooked perfectly through and has a delightful texture.

Step 6: Rest and Garnish
After baking, your Southwest Tortilla Breakfast Casserole will need a short resting period. Let it cool for about 5 minutes before serving, which allows it to set nicely. Once rested, garnish with finely chopped chives for that fresh pop of flavor and vibrant color. Enjoy this hearty dish as the ideal start to your day!

Expert Tips for Southwest Tortilla Breakfast Casserole

Prepping Ahead: Make this casserole the night before to save time in the morning. Just layer everything and let it chill in the fridge overnight.
Egg Separation: To prevent a soggy bottom, let the cooked sausage and veggies cool before adding them to the egg mixture.

Southwest Tortilla Breakfast Casserole Recipe FAQs

What type of sausage should I use?
You can use pork breakfast sausage for the classic flavor, or opt for turkey or chicken for a lighter option. If you’re looking for a vegetarian choice, plant-based sausage is a great alternative – just ensure it’s fully cooked before adding it to the casserole.

How do I store leftovers, and how long do they last?
Absolutely! Store any leftover Southwest Tortilla Breakfast Casserole in an airtight container in the refrigerator for up to 4 days. Allow it to cool completely before sealing it up to keep it fresh and delicious. Just remember to seal well to prevent it from drying out!

Can I freeze this casserole?
Yes, indeed! To freeze the casserole, wrap it tightly in foil or plastic wrap after it’s completely cooled and freeze it for up to 3 months. When you’re ready to enjoy it, simply thaw it overnight in the refrigerator. To reheat, bake it in a preheated oven at 350°F (175°C) for about 15-20 minutes until warmed through, or microwave individual servings for 1-2 minutes.

What can I do if it turns out too soggy?
If you encounter a soggy casserole, it’s likely due to excess moisture. To prevent this, make sure to drain the cooked sausage well and let it cool before mixing with the eggs. Also, ensure that the tortillas are evenly distributed and fully coated with the egg mixture. This will help maintain their integrity while baking, preventing sogginess.

Are there any dietary considerations I should keep in mind?
For those with dietary restrictions, feel free to substitute whole milk with non-dairy milk to keep it lactose-free. Additionally, if you have egg allergies, you can replace the eggs with a suitable egg replacer like flaxseed meal mixed with water (1 tablespoon ground flaxseed with 2.5 tablespoons of water per egg). Always check any additional ingredients, such as sausage and cheese, for allergens!

What toppings can I add to enhance my casserole?
The more the merrier! Top your Southwest Tortilla Breakfast Casserole with fresh chives, sliced avocado, sour cream, or fresh salsa for a delightful kick. Cheese lovers might also sprinkle a little extra shredded cheese on top before serving for added creaminess!
