Instructions

1. Preheat your oven to 350°F (175°C).
2. In a large skillet, heat the olive oil over medium heat. Add the chopped onion and sauté until translucent, about 3-4 minutes.
3. Add the minced garlic and diced jalapeños to the skillet, cooking for an additional 2-3 minutes until fragrant.
4. Increase the heat to medium-high and add the ground beef. Cook until browned, breaking it up with a spatula, about 5-7 minutes. Drain any excess fat.
5. Stir in the canned diced tomatoes (with their juice), black beans, corn, cooked rice, ground cumin, chili powder, salt, and black pepper. Mix well until all ingredients are combined and heated through.
6. Transfer the beef mixture into a greased 9x13 inch casserole dish. Sprinkle 1 cup of shredded cheddar cheese evenly over the top.
7. Bake in the preheated oven for 25-30 minutes or until heated through and cheese is bubbly.
8. Remove from the oven and let rest for 5 minutes before serving. Top with the remaining cheese and garnish with fresh cilantro if desired.
