Expert Tips

• Switch up the burritos. This recipe works with just about any kind of frozen burrito—beef, bean and cheese, chicken, or even breakfast burritos. Using different flavors keeps this frozen burrito casserole exciting every time you make it.
• Load on the toppings. After baking, add classic burrito toppings like sour cream, sliced black olives, diced avocado, jalapeños, cilantro, diced tomatoes, or shredded lettuce. These fresh toppings add texture and brightness that balance the rich, cheesy casserole.
• Try different sauces. Swap the salsa for green enchilada sauce, red enchilada sauce, or even queso for a fun twist. Each sauce gives your frozen burrito bake a slightly different flavor profile, so you can make it different each time.
• Experiment with cheeses. Monterey Jack cheese melts smoothly, cheddar adds sharpness, pepper jack brings a spicy kick, and cotija gives a salty, authentic Mexican flair. Mixing two cheeses is a great way to add depth.
• Add a crunchy topping. Sprinkle crushed tortilla chips or even Doritos on top during the last 5 minutes of baking. This gives the casserole an extra crispy layer that contrasts perfectly with the gooey cheese, and it also adds a flavorful finish.
• Cut burritos if needed. If your frozen burritos don’t fit in the baking dish, slice them in half before layering. This helps them bake more evenly and makes serving easier. You should be able to use any baking dish you have on hand, no matter the shape. 
• Pair with sides. To turn this casserole into a complete meal, serve it with refried beans, cilantro lime rice, or Mexican street corn. These sides make it feel like a restaurant-style dish.

How To Store Frozen Burrito Casserole

• In the fridge: Store your leftover burrito casserole in the casserole dish with a lid on it, or transfer everything to an airtight container and keep it in the fridge for up to 4 days. 
• In the freezer: Transfer the leftovers to an airtight container or freezer-safe bag with all the air squeezed out and freeze for about 3 months.
• How to reheat: Put the burritos back in a casserole dish and warm them in the oven at 350°F for about 10 minutes. Let the frozen burrito casserole thaw overnight in the fridge before reheating.
