I remember my first time making this. It was one of those chaotic weeks, and I needed something, well, foolproof.

It was this rich, savory aroma that just promised something good. That first bite was pure comfort—hearty, cheesy, and so satisfying. It’s become our go-to for those days when we all need a little extra care without any of the fuss.

Essential Ingredient Guide
- Ground Beef: I like to use lean ground beef (90/10) to minimize the grease, but any kind will work. Just be sure to drain it well after browning for the best texture.
- Canned Beans: Using canned beans is such a time-saver. Rinsing them before adding them to the pot helps remove excess sodium and keeps the sauce from getting cloudy.
- BBQ Sauce: The kind of barbecue sauce you use will really shape the flavor. A smoky, slightly sweet one is my favorite here, but feel free to use whatever you have on hand.
- Cheese: Oh, the cheesy topping. I find that shredding a block of sharp cheddar yourself makes all the difference. It melts so much better than the pre-shredded kind. It’s worth the tiny bit of extra effort.
Complete Cooking Process
- First, you'll want to brown your ground beef with the onion. This simple step builds a deep, savory foundation of flavor that you just can't get otherwise.
- Add the garlic at the very end so it doesn't burn—just long enough to become fragrant.
- Don't forget to drain the fat! It keeps the casserole from feeling heavy.
- Once the beef is browned, it's really just a matter of assembling. I call it the 'dump and stir' method.
- Add the beef, beans, corn, tomatoes, BBQ sauce, and all those lovely spices to the slow cooker.
- Give it all a good, gentle stir to make sure everything is mixed together.
- Arrange the tater tots or potato slices evenly over the top. This creates a wonderful crust.
- Let the slow cooker do its magic for a few hours. Just let it be.
- Right before serving, blanket the top with shredded cheese and let it melt into a glorious, gooey layer. This is the best part.
A Few Common Questions
→Can I use ground turkey or chicken instead of beef?
Yes, absolutely. Ground turkey would be a wonderful, slightly lighter alternative. Just brown it the same way you would the beef.
→Do I have to use tater tots?
Not at all! Thinly sliced potatoes work beautifully, they just might need a little longer to get tender. You could also top it with crumbled cornbread batter for the last hour of cooking for a different texture.
→Can I prepare this casserole in advance?
You can brown the beef and chop the veggies the day before to save time. I wouldn't assemble the whole thing too far in advance, as the potatoes might get discolored, but prepping the base ingredients is a great idea.
→Is this recipe spicy?
It has a mild warmth from the chili powder and green chiles. If you prefer more heat, you could add a pinch of cayenne pepper or a chopped jalapeño. For less spice, use plain diced tomatoes instead of Rotel.

For the Casserole Base
- 012 lbs lean ground beef
- 021 large yellow onion, chopped
- 033 cloves garlic, minced
- 041 (15-ounce) can pinto beans, rinsed and drained
- 051 (15-ounce) can black beans, rinsed and drained
- 061 (15-ounce) can corn, drained
- 071 (10-ounce) can diced tomatoes with green chiles (like Rotel), undrained
- 081 cup barbecue sauce
- 091 tablespoon chili powder
- 101 teaspoon cumin
- 111/2 teaspoon smoked paprika
- 12Salt and black pepper to taste
For the Topping
- 011 (20-ounce) bag frozen tater tots or 4 medium potatoes, thinly sliced
- 022 cups shredded sharp cheddar or Colby Jack cheese
- 03Fresh chives or green onions, chopped, for garnish (optional)
Instructions
In a large skillet over medium-high heat, cook the ground beef and chopped onion until the beef is browned and the onion is soft. Add the minced garlic and cook for another minute until fragrant.
Drain any excess grease from the skillet. Transfer the beef mixture to the basin of a 6-quart or larger slow cooker.
Add the rinsed pinto beans, black beans, drained corn, and the can of diced tomatoes with green chiles to the slow cooker.
Pour in the barbecue sauce and sprinkle with chili powder, cumin, smoked paprika, salt, and pepper. Stir everything together until well combined.
Arrange the frozen tater tots or sliced potatoes in an even layer over the top of the beef mixture.
Cover the slow cooker and cook on LOW for 4-6 hours or on HIGH for 2-3 hours, until the potatoes are tender and the casserole is bubbly.
Uncover and sprinkle the shredded cheese evenly over the top. Replace the lid and cook for another 10-15 minutes, or until the cheese is completely melted and gooey.
Let the casserole rest for a few minutes before serving. Garnish with fresh chives or green onions if you like. Serve warm.
Notes & Tips
- 1A 6-quart slow cooker is the perfect size for this recipe.
- 2Feel free to swap the beans for what you have on hand—kidney or cannellini beans would also be great.
- 3If using sliced potatoes, make sure they are in a single, even layer to ensure they cook through.
Tools You'll Need
- •Always brown the ground beef before adding it to the slow cooker. It adds so much flavor.
- •Rinse and drain your canned beans and corn to control the sodium and improve the texture of the sauce.
- •For the best, meltiest cheese topping, shred your own cheese from a block.
- •Don't lift the lid while it's cooking! Every time you do, you release heat and add to the cooking time.
