Ingredients

Servings: 6

• 8 frozen burritos, about 5–6 ounces each
• 1 can (19 ounces) red enchilada sauce
• 1 1/2 cups shredded Mexican-blend cheese
• 1/2 cup shredded cheddar cheese
• 1/4 cup sliced green onions
• 2 tablespoons chopped fresh cilantro, optional
• 1/2 cup sour cream, for serving
• 1/4 cup sliced black olives, optional
• 1/4 cup diced tomatoes, optional

Ingredient Notes

Frozen burritos: Choose burritos that fit comfortably in a 9×13-inch baking dish. Bean and cheese, beef, chicken, or combination burritos can work.

Enchilada sauce: Red enchilada sauce provides moisture and a savory chile flavor while the casserole bakes. Use mild or spicy sauce depending on your preference.

Cheese: A Mexican-blend cheese melts easily and adds a good mix of flavors. Cheddar adds extra sharpness and color.

Green onions: Add them after baking for a fresh contrast to the rich, cheesy casserole.

Toppings: Sour cream, cilantro, tomatoes, and black olives are optional. They are best added after baking rather than baked into the casserole.

How to Make Easy Frozen Burrito Casserole

1. Prepare the Baking Dish

Preheat the oven to 375°F. Lightly grease a 9×13-inch baking dish with nonstick cooking spray or a thin coating of oil.

2. Arrange the Frozen Burritos

Place the 8 frozen burritos in the prepared baking dish in a single layer. Arrange them snugly but avoid stacking them on top of one another.

3. Add the Enchilada Sauce

Pour the red enchilada sauce evenly over the burritos. Use a spoon or spatula to spread it so the tops are well coated and some sauce reaches the spaces between the burritos.

4. Cover With Cheese

Sprinkle the Mexican-blend cheese evenly over the sauced burritos, followed by the shredded cheddar. Try to cover most of the surface so the cheese melts into a cohesive topping.

5. Bake Until Hot and Bubbly

Bake uncovered for 35–40 minutes, or until the burritos are heated through and the sauce is bubbling around the edges. The cheese should be completely melted and lightly golden in spots.

6. Rest and Add the Toppings

Let the casserole rest for 5 minutes before serving. Sprinkle with sliced green onions and cilantro, then add sour cream, diced tomatoes, or black olives if desired.

Recipe Tips

• Keep the burritos frozen: There is no need to thaw them first. Starting frozen helps keep the assembly quick and lets the burritos heat gradually in the oven.
• Spread the sauce evenly: Sauce on top helps prevent the exposed burrito surfaces from becoming excessively dry during baking.
• Don’t pile up the burritos: A single layer allows the heat and sauce to reach the burritos more evenly.
• Watch the cheese near the end: If the cheese becomes deeply browned before the burritos are hot, loosely cover the dish with foil for the remaining baking time.
• Let it rest briefly: A five-minute rest makes the casserole easier to serve and gives the hot sauce and cheese a chance to settle.
• Use toppings after baking: Fresh toppings such as green onions, tomatoes, cilantro, and sour cream provide brightness against the rich baked cheese.

Can You Use Different Frozen Burritos?

Yes. This casserole is flexible enough for several frozen burrito varieties.

Bean-and-cheese burritos create a simple meatless version, while beef, chicken, or bean-and-beef burritos make the casserole heartier. If using unusually large burritos, you may need to adjust the arrangement or use a larger baking dish.

The main thing to watch is the burrito size. Smaller burritos may heat faster, while larger burritos can require additional baking time.

How to Know When the Burritos Are Done

The casserole should be hot and bubbling throughout, with melted cheese across the top. Because frozen burrito sizes and fillings vary, cooking time can differ slightly.

For the most reliable result, check the center of a burrito before serving. It should be steaming hot all the way through rather than merely warm around the edges.

Variations and Substitutions

• Spicy version: Use hot enchilada sauce and add sliced jalapeños after baking.
• Chicken version: Use frozen chicken burritos with a Mexican cheese blend.
• Vegetarian version: Choose bean-and-cheese or vegetable frozen burritos.
• Extra cheesy: Add another 1/2 cup of shredded cheese during the final 10 minutes of baking.
• Creamy topping: Replace some of the sour cream with a spoonful of guacamole.
• Different sauce: Green enchilada sauce can replace red enchilada sauce for a different flavor profile.
• Cheese swap: Monterey Jack, Colby Jack, or a cheddar-Monterey Jack blend can replace the Mexican-blend cheese.

What to Serve With Frozen Burrito Casserole

Because the casserole is already hearty, simple sides work well:

• Green salad with a light vinaigrette
• Mexican-style rice
• Black beans or pinto beans
• Corn salad
• Sliced avocado or guacamole
• Fresh salsa and tortilla chips

Storage and Reheating

Refrigerator: Transfer cooled leftovers to an airtight container or cover the baking dish tightly. Refrigerate for up to 3–4 days.

Reheating individual portions: Microwave a serving until heated through, checking and stirring or rotating as needed. The exact time depends on portion size and microwave power.

Reheating in the oven: Place portions in an oven-safe dish, cover loosely with foil, and heat at 350°F until hot throughout.

Freezing leftovers: The casserole can be frozen after baking, although the texture of the tortilla and cheese may change somewhat after thawing and reheating. Cool completely, portion into freezer-safe containers, and use within about 2–3 months for best quality.
