Method
 

Casserole Preparation
  1. Preheat your oven to 375°F (190°C). Lightly coat your white rectangular ceramic baking dish with non-stick cooking spray or olive oil.
  2. Heat a large skillet over medium-high heat with 1 tbsp olive oil. Cook 1 lb ground beef until browned and crumbled. Drain excess fat.
  3. Add 2 tbsp taco seasoning and 1/4 cup beef broth to the skillet. Simmer for 2-3 minutes until it becomes a saucy glaze.
  4. Stir in the lightly drained diced roasted tomatoes, rinsed black beans, and yellow corn kernels. Heat through for 3 minutes.
  5. Transfer the mixture to the prepared baking dish. Top evenly with 1.5 cups sharp cheddar and 1.5 cups Monterey Jack cheese.
  6. Bake uncovered for 15-20 minutes until the cheese is thick, bubbly, and the edges are perfectly browned and crispy.
  7. Let rest for 5 minutes. Garnish with thick dollops of sour cream, sliced green jalapeno rings, diced purple onions, and chopped cilantro leaves.

Notes

Freshly grate your cheese for the best bubbly melt.
Drain and rinse the black beans well to ensure the filling stays saucy and not watery.
