Step-by-Step Instructions

Step 1: Prepare the Ingredients

Dice the onion and mince the garlic. Drain and rinse the black beans and corn. Open the diced tomatoes and set aside. Measure out the spices, shredded cheese, tomato paste, and broth to ensure a smooth cooking process.

Step 2: Sauté the Aromatics

In a skillet over medium heat, heat the olive oil. Add the diced onion and cook for 3 to 4 minutes until softened. Add the garlic and cook for another 30 seconds until fragrant. This step enhances the flavor of the casserole and creates a rich aromatic base.

Step 3: Brown the Ground Beef

Add the ground beef to the skillet and cook until browned, breaking it up with a spoon. Season with salt, pepper, chili powder, cumin, and smoked paprika while cooking. Drain any excess fat if necessary. Browning the meat before adding to the slow cooker intensifies the beef flavor and ensures a tender texture.

Step 4: Assemble the Casserole in the Slow Cooker

Transfer the browned beef, sautéed onions, and garlic to the slow cooker. Add the black beans, corn, diced tomatoes with green chilies, tomato paste, and beef broth. Stir to combine. If using cooked rice, fold it in gently. Spread the mixture evenly in the slow cooker.

Step 5: Slow Cook

Cover and cook on low for 4 to 6 hours. Check for doneness around 4 hours; the flavors should meld, and vegetables should be tender. The mixture should be slightly thickened and bubbling around the edges.

Step 6: Add Cheese and Finish

Thirty minutes before serving, sprinkle shredded cheddar cheese over the top. Cover and allow the cheese to melt completely. You can also add extra toppings like sliced green onions, diced avocado, or a dollop of sour cream just before serving for added flavor and presentation.

Step 7: Cool Slightly and Serve

Once cooked, let the casserole rest for 5 to 10 minutes to allow it to set slightly. This makes serving easier and ensures each portion holds together.

How to Serve

Serve slow cooker cowboy casserole warm straight from the Crockpot for easy weeknight dinners or large gatherings. Scoop portions onto plates and garnish with fresh chopped herbs such as parsley, cilantro, or green onions to add a pop of color and freshness. For added flavor and presentation, sprinkle extra shredded cheese or crushed tortilla chips on top before serving. This also works beautifully when serving a crowd, as it allows guests to customize toppings to their liking.

Pair the casserole with simple sides to complete the meal. A fresh green salad, steamed or roasted vegetables, or a side of cornbread complements the rich, hearty flavors of the casserole. For casual gatherings, serve alongside tortilla chips, salsa, or guacamole for a fun, Tex-Mex inspired spread. Keep the Crockpot on the “warm” setting if serving buffet-style to maintain the ideal serving temperature. For a family-friendly approach, allow each person to build their plate with optional toppings like avocado, sour cream, or jalapeños.

Additional Tips

Use a well-sized slow cooker to prevent overfilling, which can affect cooking times.
Sautéing the meat and aromatics before adding to the slow cooker enhances flavor and prevents a raw taste.
Stir the casserole halfway through cooking if possible to ensure even heat distribution.
Adjust seasoning near the end, as slow cooking can mellow spices.
Avoid lifting the lid repeatedly to maintain steady cooking temperature.
