Preheat Oven: Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish with non-stick cooking spray.
Cook the Meat: In a large skillet over medium-high heat, add the ground beef. Cook, breaking it into small crumbles, until deeply browned (about 5-7 minutes).
Sauté Aromatics: Add the diced onion to the beef and cook for 3-4 minutes until softened. Add the minced garlic and cook for 1 more minute until fragrant. Carefully drain excess grease from the skillet.
Create the Filling: Reduce heat to medium-low. Stir in the drained corn, beans, Worcestershire sauce, smoked paprika, salt, and pepper.
Add the Creamy Binder: Remove the skillet from the heat. Fold in the condensed soup and sour cream until the mixture is evenly coated and creamy.
Assemble: Pour the beef mixture into your prepared 9x13 baking dish, spreading it out into an even, flat layer.
Add Cheese & Tots: Sprinkle the freshly grated cheddar cheese evenly over the beef mixture. Next, arrange the frozen tater tots in a single, tight layer across the entire top of the casserole.
Bake: Bake uncovered for 40 to 45 minutes, or until the filling is bubbling around the edges and the tater tots are deeply golden brown and crispy.
Rest and Serve: Remove from the oven and let the casserole rest for 10 minutes before serving. This allows the sauce to set up perfectly. Enjoy!
