With just a little prep, you can let the slow cooker do most of the work. It’s a great option for busy weeknights, casual gatherings, or whenever you’re craving a warm and satisfying comfort meal.

Ingredients
- 1 pound lean ground beef
- 1 cup finely diced sweet yellow onion
- 1 tablespoon minced garlic
- 1 can (16 ounces) dark red kidney beans, undrained
- 1 can (14.5 ounces) petite diced tomatoes, with juice
- 1 can (10 ounces) diced tomatoes with fire-roasted Hatch chilies, with juice
- 1 cup frozen corn
- 1 teaspoon kosher salt
- ½ teaspoon freshly cracked black pepper
- ¼ teaspoon chipotle powder
- 1½ pounds Yukon Gold potatoes, sliced about ⅛ inch thick
- 1¼ cups freshly shredded Colby and Monterey Jack cheese
How to Make It
1. Prepare the slowcooker
Lightly coat the inside of your slow cooker with nonstick cooking spray.
2. Brown the beef
Heat a large skillet over medium-high heat. Add the ground beef, diced onion, and minced garlic. Cook until the beef is completely browned and no longer pink.
Drain off any excess grease, then transfer the beef mixture to the slow cooker.
3. Add the remaining ingredients
Add the kidney beans, both cans of tomatoes, frozen corn, salt, black pepper, and chipotle powder.
Stir everything together until the ingredients are evenly combined.
4. Add the potatoes
Remove about 1½ cups of the meat mixture and set it aside.
Arrange the sliced Yukon Gold potatoes throughout the slow cooker, then spoon the reserved meat mixture evenly over the potatoes.
5. Slow cook
Cover the slow cooker and cook until the potatoes are tender:
- High: about 5 hours
- Low: about 7 hours
Cooking times can vary slightly depending on your slow cooker and the thickness of your potato slices.
6. Add the cheese
When the casserole is finished cooking, sprinkle the shredded Colby and Monterey Jack cheese over the top.
Cover the slow cooker again and allow it to sit for a few minutes, until the cheese is completely melted.
7. Serve
Scoop the casserole into bowls and serve while hot. The combination of savory beef, tender potatoes, beans, vegetables, and melted cheese makes this a hearty meal all on its own.
Helpful Tips
- Use thin potato slices: Cutting the potatoes to roughly ⅛ inch helps them cook evenly.
- Adjust the heat: The chipotle powder and fire-roasted chilies add a little smoky warmth. For a milder casserole, reduce the chipotle powder or use regular diced tomatoes.
- Try different beans: Pinto or black beans can be substituted for kidney beans if preferred.
- Make it ahead: Leftovers can be refrigerated in an airtight container and reheated for an easy second meal.
- Add extra toppings: Green onions, fresh parsley, sour cream, or additional shredded cheese can be added before serving.
Storage

Allow leftovers to cool before transferring them to an airtight container. Refrigerate and enjoy within about 4 days.
For longer storage, portion the casserole into freezer-safe containers and freeze for up to 3 months. Thaw in the refrigerator before reheating.
