Ingredients

Scale
  • 1 tablespoon olive oil
  • 1 pound ground beef
  • 1 medium onion, chopped
  • 2 cloves garlic, minced
  • 1 (10 ounce) can Ro-Tel diced tomatoes and green chilies, undrained
  • 1 (15 ounce) can black beans, rinsed and drained
  • 1 (10 ounce) can mild enchilada sauce
  • 1 cup uncooked long-grain white rice
  • 2 cups chicken broth
  • 1 teaspoon chili powder
  • 1 teaspoon ground cumin
  • 1/2 teaspoon dried oregano
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 cup frozen corn
  • 2 cups shredded Mexican cheese blend

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. Heat the olive oil in a large skillet over medium heat. Add the ground beef and cook until browned, breaking it up as it cooks. Drain off any excess grease.
  3. Add the chopped onion to the skillet and cook until softened, about 5 minutes. Stir in the minced garlic and cook for 1 minute more until fragrant.
  4. Stir in the Ro-Tel, black beans, enchilada sauce, uncooked rice, chicken broth, chili powder, cumin, oregano, salt, and pepper. Bring the mixture to a boil.
  5. Once boiling, reduce the heat to low, cover the skillet, and simmer for 15 minutes, or until the rice has absorbed most of the liquid. Do not lift the lid during this time.
  6. Remove the skillet from the heat. Stir in the frozen corn.
  7. Transfer the rice mixture to your prepared baking dish. Sprinkle the shredded cheese evenly over the top.
  8. Bake uncovered for 15 to 20 minutes, or until the cheese is melted, bubbly, and lightly golden brown.
  9. Let the casserole rest for 5 minutes before you serve it.

Notes

  • For a lighter meal, substitute ground turkey for the ground beef.
  • You can prepare this dish ahead of time; cover and refrigerate before baking. Add 10 minutes to the baking time if cooking directly from the refrigerator.
  • Serve this hearty rice bake with sour cream, chopped cilantro, or sliced avocado for extra flavor.
