Overnight Breakfast Burrito Casserole Ingredients
For the Casserole
- Small Flour Tortillas (20, fajita size) – The perfect base for the burritos; consider using corn tortillas for a gluten-free option.
- Ground Breakfast Sausage (1 pound, hot) – Adds hearty spiciness and richness; swap for ground turkey or chicken for a lighter flavor.
- Diced Tomatoes & Green Chiles (1 can, undrained) – Infuses moisture and zesty flavor; using the RoTel brand elevates the dish.
- Butter (2 tablespoons) – Ideal for frying hashbrowns, but you can substitute with olive oil for a dairy-free dish.
- Shredded Hashbrowns (20 ounces) – Adds satisfying texture; frozen hashbrowns can be used straight from the bag without thawing.
- Shredded Colby Jack Cheese (2.5 cups) – Brings creaminess and flavor; try cheddar cheese for a sharper taste if you prefer.
- Large Eggs (12) – Binds the casserole and packs protein; egg substitutes can lighten the dish if desired.
- Half & Half (1 cup) – Creates a rich, creamy base; use milk or a dairy-free alternative like oat milk for similar results.
- Sour Cream (1 cup) – Adds a tangy lift; plain yogurt can be a lighter alternative in its place.
- Salt (½ teaspoon, divided) – Enhances all flavors; adjust according to dietary needs.
- Pepper (½ teaspoon, divided) – Provides seasoning; fresh ground pepper offers the best flavor boost.
For Baking
- Plastic Wrap – Essential for refrigerating the casserole; ensure it’s tightly covered to prevent drying out before baking.

Step‑by‑Step Instructions for Overnight Breakfast Burrito Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms, grab two 9×13 baking dishes and lightly spray them with non-stick cooking spray to ensure your Overnight Breakfast Burrito Casserole won’t stick when baked.
Step 2: Brown the Sausage
In a large skillet over medium heat, add the pound of ground breakfast sausage. Cook for about 5–7 minutes, breaking it apart with a spatula, until it’s no longer pink. Incorporate the can of diced tomatoes and green chiles (draining excess liquid first to prevent sogginess), allowing the mix to simmer for another 2 minutes until heated through and well combined.
Step 3: Cook the Hashbrowns
In the same skillet, melt 2 tablespoons of butter over medium heat. Add the frozen hashbrowns and sprinkle with half of the salt and pepper (¼ teaspoon each). Cook for 8–10 minutes, stirring occasionally, until the hashbrowns are golden and crispy on the edges, then remove from heat.
Step 4: Combine Filling Ingredients
In a large mixing bowl, combine the browned sausage mixture, crispy hashbrowns, and 2 cups of shredded Colby Jack cheese, mixing carefully to nicely incorporate all the flavors. This savory filling is what will make your Overnight Breakfast Burrito Casserole truly delicious.
Step 5: Fill the Tortillas
Take a small flour tortilla and lay it flat. Spoon about ¼ cup of the filling into the center, rolling it tightly to enclose the ingredients. Place each rolled tortilla seam-side down inside the prepared baking dishes, arranging them snugly for an even bake. Repeat until all tortillas are filled.
Step 6: Prepare the Egg Mixture
In a separate bowl, whisk together 12 large eggs with 1 cup of half & half, 1 cup of sour cream, and the remaining salt and pepper. Ensure everything is combined smoothly for a creamy base that will soak into your casserole overnight, enhancing the overall flavor of the dish.
Step 7: Assemble the Casserole
Slowly and evenly pour the egg mixture over the rolled tortillas in the baking dishes, making sure to cover all tortillas. To finish, sprinkle the remaining ½ cup of shredded cheese over the top, allowing it to create a golden crust when baked.
Step 8: Refrigerate Overnight
Cover each baking dish tightly with plastic wrap, ensuring no air can escape. Refrigerate the Overnight Breakfast Burrito Casserole for a minimum of 30 minutes, or up to overnight. This allows the flavors to meld beautifully and the tortillas to soak in the egg mixture.
Step 9: Bake the Casserole
When ready to bake, let the casserole sit at room temperature for about 30 minutes to ensure even cooking. Place the dishes in the preheated oven and bake for 30–40 minutes, or until the egg is set and the top is golden brown. Keep an eye on it—if it browns too quickly, tent it with foil.
Step 10: Serve and Enjoy
Once done, remove your Overnight Breakfast Burrito Casserole from the oven and let it cool for a few minutes. Serve warm alongside your favorite toppings, like avocado slices, salsa, or a dollop of sour cream, and gather everyone to enjoy this hearty breakfast feast!

Make Ahead Options
These Overnight Breakfast Burrito Casseroles are a lifesaver for busy mornings and meal prep enthusiasts! You can assemble the entire casserole up to 24 hours in advance before baking. Simply prepare the filling, roll the tortillas, and pour the egg mixture over them. Cover the dishes tightly with plastic wrap and refrigerate; this allows the flavors to meld beautifully while ensuring the tortillas soak in the egg mixture for optimal flavor. When you’re ready to serve, let the casserole sit at room temperature for about 30 minutes before baking to ensure even cooking. This way, you’ll have a delicious, hearty breakfast ready to go with minimal effort!

It will stay fresh in the freezer for up to 3 months. When you’re ready to eat, simply thaw it overnight in the refrigerator and bake as directed.
What if my casserole is too watery when baking?
