Instructions
Step 1 – Brown the Beef
Heat a large skillet over medium heat.
Add the ground beef and cook until fully browned, breaking it into small crumbles.
Drain any excess grease.
Step 2 – Prepare the Potatoes
Wash and chop the potatoes into bite-sized cubes so they cook evenly.
Step 3 – Layer the Ingredients
Lightly grease the slow cooker.
Layer in the following order:
- Half of the chopped potatoes
- Half of the browned beef
- Half of the kidney beans
- Half of the corn
Repeat with the remaining ingredients.
Step 4 – Add the Sauce
Pour the tomato sauce evenly over everything.
Sprinkle with:
- Garlic powder
- Onion powder
- Smoked paprika
- Salt
- Black pepper
Gently stir just enough to distribute the seasonings.
Step 5 – Slow Cook
Cover with the lid.
Cook:
- LOW: 6–8 hours
- HIGH: 3–4 hours
The casserole is ready when the potatoes are fork-tender.
Step 6 – Add the Cheese
During the final 30 minutes of cooking, sprinkle the shredded cheddar cheese evenly over the top.
Cover again and allow the cheese to melt completely.
Step 7 – Serve
Spoon into bowls while hot.
Top with sour cream, chopped chives, parsley, or sliced green onions if desired.

- Stir gently near the end to avoid breaking up the potatoes.
- Add crispy bacon, diced bell peppers, or sliced jalapeños for extra flavor.

Frequently Asked Questions

Yes! Ground turkey or ground chicken works well for a lighter version.
Can I prepare it ahead of time?
Absolutely. Assemble everything the night before, refrigerate the slow cooker insert, and start cooking the next day.
Can I add more vegetables?
Yes. Bell peppers, carrots, celery, peas, or diced tomatoes are excellent additions.
What cheese works best?
Sharp cheddar is classic, but Monterey Jack, Pepper Jack, Colby Jack, or a Mexican cheese blend also melt beautifully.
