Ingredients & Their Role in the Recipe

1 lb Ground Beef – The foundation of the dish, providing rich, savory flavor and protein that makes this casserole hearty and satisfying.
1 Medium Onion, Chopped – Adds natural sweetness and depth, enhancing the overall flavor profile as it cooks down with the beef.
1 Can (15 oz) Corn Kernels, Drained – Brings a subtle sweetness and pleasant texture that balances the bold spices.
1 Can (15 oz) Black Beans, Drained & Rinsed – Adds creaminess, fiber, and protein, making the casserole extra filling.
1 Can (10 oz) Diced Tomatoes with Green Chilies – Infuses the dish with moisture, acidity, and a mild kick of heat.
1 Packet Taco Seasoning Mix – The flavor powerhouse, delivering smoky, spicy, and savory notes in one easy step.
1 Cup Shredded Cheddar Cheese – Melts beautifully over the top, adding richness and irresistible cheesiness.
1 Cup Frozen Tater Tots – Creates a crispy, golden topping that contrasts perfectly with the creamy casserole base.
Salt & Pepper to Taste – Essential for balancing and enhancing all the flavors.
½ Cup Sour Cream (Optional) – A cool, tangy finish that complements the bold flavors beautifully.

Step-by-Step Instructions

1. Brown the Ground Beef

In a skillet over medium heat, cook the ground beef together with the chopped onion. Stir occasionally until the beef is fully browned and the onion becomes soft and translucent. Drain any excess grease to prevent the casserole from becoming oily.

2. Assemble the Casserole Base

Transfer the cooked beef and onion mixture into your slow cooker. Add the corn kernels, black beans, diced tomatoes with green chilies, and the taco seasoning mix. Stir thoroughly until everything is evenly combined and coated in seasoning.

3. Slow Cook to Perfection

Cover the slow cooker and cook on LOW for 4 hours or HIGH for 2 hours. This slow cooking process allows all the flavors to meld together into a rich, comforting casserole base.

4. Add the Tater Tot Topping

Once the casserole has cooked, arrange the frozen tater tots evenly over the top. Cover and continue cooking for an additional 30 minutes, or until the tater tots are golden and slightly crispy.

5. Finish with Cheese

Sprinkle the shredded cheddar cheese generously over the hot tater tots. Cover and let the cheese melt for 5–10 minutes until perfectly gooey.

6. Serve & Enjoy

Scoop the casserole onto plates and, if desired, add a dollop of sour cream for extra creaminess and flavor.
