Ingredient Notes
Frozen burritos: Beef, bean-and-cheese, chicken, or another favorite variety can work. Choose burritos that fit comfortably in your baking dish.
Enchilada sauce: Red enchilada sauce adds moisture and savory flavor while the casserole bakes.
Cheese: A combination of cheddar and Monterey Jack gives the casserole both sharp flavor and good melting.
Green chiles: These add a mild pepper flavor. Leave them out if you prefer a simpler casserole.
Toppings: Sour cream, green onions, and cilantro can be added after baking for freshness and contrast.
How to Make Frozen Burrito Casserole
1. Prepare the Oven and Baking Dish
Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish so the casserole is easier to serve and clean up afterward.
2. Arrange the Frozen Burritos
Place the frozen burritos in a single layer inside the prepared baking dish. Arrange them snugly so they stay together while baking.
3. Add the Sauce
Pour the red enchilada sauce evenly over the burritos, making sure most of their surfaces are covered. Sprinkle the diced green chiles over the top.
4. Add the Cheese
Sprinkle the cheddar and Monterey Jack cheeses evenly over the sauced burritos. Try to cover the casserole from edge to edge for a cheesy baked topping.
5. Bake the Casserole
Cover the baking dish loosely with aluminum foil and bake for about 30 minutes. Remove the foil and continue baking for another 10 to 15 minutes, or until the burritos are heated through and the cheese is melted and lightly browned.
6. Rest Before Serving
Remove the casserole from the oven and let it rest for about 5 minutes. This gives the bubbling sauce and melted cheese a chance to settle slightly.
7. Add Toppings and Serve
Top with sour cream, sliced green onions, and fresh cilantro if desired. Serve warm while the cheese is still soft and melty.
Recipe Tips
- Keep the burritos frozen: There’s no need to thaw them before assembling the casserole.
- Use enough sauce: Covering the burritos well helps prevent dry edges.
- Watch the cheese: Once the foil is removed, check the casserole during the final baking period so the cheese doesn’t become overly dark.
- Let it rest: A short resting period makes the casserole easier to portion.
- Customize the toppings: Add diced avocado, jalapeños, tomatoes, black olives, or additional green onions.
- For extra flavor: Sprinkle a little taco seasoning over the burritos before adding the cheese.
Can You Use Different Frozen Burritos?
Absolutely. This casserole is flexible because the frozen burritos are the main ingredient.
Try:
- Beef burritos for a hearty version
- Bean-and-cheese burritos for a meatless option
- Chicken burritos for a lighter variation
- Spicy burritos if you enjoy more heat
- Smaller frozen burritos for individual portions
The baking time may vary depending on the size and filling of the burritos, so make sure they are heated thoroughly before serving.
How to Make It More Filling
For a heartier casserole, add extra ingredients around or over the burritos before baking.
Good options include:
- Black beans
- Corn
- Diced bell peppers
- Sautéed onions
- Extra shredded cheese
- Sliced jalapeños
Keep additions moderate so the burritos still have enough room to heat evenly.
Variations and Substitutions
Make It Spicier
Use hot enchilada sauce, spicy frozen burritos, or sliced jalapeños.
Add Black Beans
Scatter drained and rinsed black beans around the burritos for additional texture and substance.
Try Green Enchilada Sauce
Swap the red enchilada sauce for green enchilada sauce for a different flavor profile.
Change the Cheese
Use Mexican-style shredded cheese, pepper Jack, Colby Jack, or a combination of your favorites.
Add Fresh Toppings
Finish individual servings with avocado, pico de gallo, shredded lettuce, tomatoes, or a squeeze of fresh lime.
What to Serve With Frozen Burrito Casserole
This casserole is filling on its own, but simple sides can round out the meal:
- Mexican-style rice
- Black beans
- Corn salad
- Simple green salad
- Guacamole and tortilla chips
- Fresh salsa
- Roasted vegetables
For a casual dinner, serve it directly from the baking dish with a selection of toppings so everyone can customize their portion.
Storage and Reheating
Store leftover casserole in an airtight container in the refrigerator and use it within 3 to 4 days.
For reheating, place an individual portion in the microwave and heat until warmed through. For a larger amount, cover it with foil and warm it in a 350°F oven until heated through.
Because frozen burritos can vary in size and filling, check that leftovers are hot throughout before serving.
