Heat olive oil in a large skillet over medium heat.
Add the chopped onion and cook until softened, about 3-4 minutes.
Add the minced garlic and cook for an additional 1 minute.
Add the ground beef to the skillet, breaking it apart with a wooden spoon. Cook until browned and cooked through, about 6-8 minutes.
Stir in the taco seasoning and water, and cook for an additional 2 minutes, allowing the flavors to meld.
Add the black beans, corn, and salsa (or diced tomatoes) to the beef mixture. Stir to combine and heat through. Remove from heat and set aside.
2. Assemble the Burritos
Preheat your oven to 375°F (190°C).
Place a large flour tortilla on a flat surface. Spoon a portion of the beef mixture onto the center of the tortilla.
Sprinkle with shredded cheddar cheese.
Fold in the sides of the tortilla and then roll it up from the bottom to the top, securing the filling inside. Place the burrito seam-side down in a baking dish.
Repeat with the remaining tortillas and beef mixture.
3. Bake the Burritos
Once all the burritos are assembled and placed in the baking dish, sprinkle the shredded mozzarella cheese evenly over the top.
Bake in the preheated oven for 15-20 minutes, or until the cheese is melted and bubbly and the tortillas are crispy.
4. Serve
Remove the burritos from the oven and let them cool slightly before serving.
Garnish with chopped fresh cilantro and serve with sour cream, guacamole, and sliced jalapeños if desired.
Notes and Tips
Cheese Variations: Feel free to use a blend of cheeses, such as Monterey Jack, pepper jack, or a Mexican cheese blend, for different flavor profiles.
Beef Alternatives: You can substitute ground beef with ground chicken, turkey, or even a plant-based protein for a different twist.
Make-Ahead: You can prepare the beef mixture ahead of time and store it in the refrigerator for up to 2 days. Assemble and bake the burritos when ready to serve.
Freezing: Assemble the burritos and freeze them before baking. To cook from frozen, bake at 375°F (190°C) for 25-30 minutes.
