1-First Step: Preheat and Prep Begin by preheating your oven to 375°F and lightly spraying a baking dish with non-stick spray. This step is crucial for even cooking and easy cleanup. In a large skillet, cook the 1 ⅓ lb lean ground beef, 1 cup diced yellow onion, and 1 cup diced red bell pepper over medium heat until the beef is fully browned. Drain the mixture well to remove excess fat, which helps keep your Cowboy Cornbread Casserole from becoming greasy.

2-Second Step: Add Aromatics and Mix-Ins Once the beef mixture is drained, add the 1 clove minced garlic and cook for about one minute to release its flavor. For those wanting variations, this is a good spot to incorporate extras like jalapeños if you desire more heat. Stir in the 10 oz can of diced tomatoes with green chilies, 15.5 oz canned pinto beans (drained first), 15.25 oz canned corn, and 1 oz taco seasoning. Mix everything thoroughly and spread it evenly into your prepared baking dish for an even base.

3-Third Step: Prepare the Cornbread Batter In a separate bowl, whisk together 1 cup cornmeal, 1 cup all-purpose flour, ¼ cup granulated sugar, 1 tablespoon baking powder, and 1 teaspoon salt. This dry mix forms the foundation of your topping. In another bowl, combine 1 cup whole milk, 2 large eggs, and 5 tablespoons melted unsalted butter. For dietary tweaks, use non-dairy milk here if needed. Pour the wet ingredients into the dry ones, whisk until just combined, and gently fold in 1 cup shredded cheddar cheese to add that melty goodness.

4-Fourth Step: Assemble and Bake Spoon the cornbread batter over the beef mixture in the baking dish, spreading it to the edges for full coverage. This creates the signature layered effect of a Ground Beef Cowboy Casserole. Pop it into the preheated oven and bake for 25-30 minutes. Check for doneness by inserting a toothpick into the cornbread it should come out clean, and the top should be golden brown. If adapting for preferences, add a few minutes if using substitutions.

5-Final Step: Garnish and Serve Once baked, remove the casserole and let it cool slightly before garnishing with options like cilantro, sour cream, salsa, avocado, green onions, or jalapeño peppers. Serve it warm as a complete meal, perhaps with a side of fresh veggies for extra nutrition.
