Step-by-Step Instructions

Here’s how to make this Slow Cooker Cowboy Casserole perfectly every time.

Step 1: Brown the Ground Beef

Heat a skillet over medium heat and add 1 lb ground beef. Cook until fully browned, breaking it apart with a wooden spoon. Drain excess fat to keep the dish from being greasy.

Step 2: Combine Ingredients in Slow Cooker

Add the cooked beef to the slow cooker along with:

• 1 can black beans
• 1 can corn
• 1 can diced tomatoes with green chilies
• 1 packet taco seasoning
• 1 cup diced onion
• 1 cup diced bell pepper
• 1 cup beef broth

Stir well to evenly distribute the flavors.

Step 3: Add Tater Tot Topping

Top the mixture with 4 cups frozen tater tots in an even layer. Sprinkle 2 cups shredded cheddar cheese over the top for a golden, melty finish.

Step 4: Slow Cook

Cover and cook on low for 6–8 hours or high for 3–4 hours. The tater tots will soften and the flavors will meld into a rich, hearty casserole.

Step 5: Serve

Once cooked, serve immediately while hot. The top will be golden, the cheese melted, and the filling packed with flavor. Garnish with chopped green onions or fresh cilantro if desired.
