Ingredients for Crockpot Cowboy Casserole
Main Ingredients:

- 3-4 medium potatoes, sliced ¼ inch thick
- 1 can (15 oz) kidney beans, drained
- 2 cans (15 oz each) diced tomatoes
- 1 green bell pepper, diced
- 1 cup frozen corn
- 1 onion, diced
- 3 garlic cloves, minced
- ½ cup beef stock (or chicken stock)
For Topping:
- ½ cup shredded cheddar cheese (or more!)
Seasoning:
- ½ teaspoon Italian seasoning
- ½ teaspoon paprika
- ¼ teaspoon chili powder (optional for heat)
- ¼ teaspoon black pepper
- ¼ teaspoon salt
How to Make Crockpot Cowboy Casserole
Step 1: Prep the Ingredients
Peel and dice the onion. Mince or grate the garlic cloves. Slice potatoes into ¼-inch thick rounds. Dice the bell pepper. Having everything prepped makes assembly quick and easy!
Step 2: Brown the Ground Beef
Heat a skillet over medium heat. Add ground beef and cook for 5-7 minutes, breaking it up with a spoon, until browned and no longer pink. This step adds flavor and ensures the meat is cooked through.
Step 3: Sauté Aromatics
Add diced onion and minced garlic to the skillet with the beef. Sauté for 1-2 minutes until onion is soft and translucent and garlic is fragrant.
Step 4: Add Everything to Slow Cooker
Transfer the beef, onion, and garlic to your slow cooker. Add sliced potatoes, diced tomatoes, diced bell pepper, corn, beef stock, and all seasonings (Italian seasoning, paprika, chili powder, salt, and pepper). Stir well to combine everything evenly.
Step 5: Slow Cook
Cover with the lid and cook on HIGH for 3-4 hours or LOW for 6-8 hours. The casserole is done when potatoes are fork-tender and easily pierced.
Step 6: Add Beans and Cheese
Once potatoes are cooked, stir in drained kidney beans. Top the entire casserole with shredded cheddar cheese. Cover and cook on LOW for 10-15 minutes until cheese is melted and bubbly.
Step 7: Serve
Serve hot directly from the slow cooker. This casserole is a complete meal on its own or pair with your favorite sides!
Pro Tips for Perfect Cowboy Casserole
Brown the Beef First – This adds flavor and ensures the meat is fully cooked. Don’t skip this step!
Slice Potatoes Evenly – Uniform ¼-inch slices ensure all potatoes cook at the same rate.
Check Potato Doneness – Make sure potatoes are fork-tender before adding cheese. Thick slices may need extra cooking time.
Keep the Lid On – Don’t peek! Opening the slow cooker releases heat and increases cooking time.
Customize Freely – This recipe is forgiving! Add any vegetables or seasonings you like.
Use Lean Ground Beef – This reduces excess grease. If using regular beef, drain after browning.
Layer Potatoes on Bottom – They take longest to cook, so placing them on the bottom helps them cook evenly.
Add Beans Later – Adding beans at the end prevents them from becoming mushy during long cooking.

Frequently Asked Questions
Can I make this without potatoes? Yes! Simply omit the potatoes and beef stock. You’ll have more of a beef and bean chili consistency.
Why is my casserole watery? If too watery, thicken with cornstarch slurry (1 tablespoon cornstarch + 2 tablespoons water), instant mashed potato powder, or mash some of the potatoes and beans in the casserole.
Can I add the beans at the beginning? Yes, though they may become softer. Many cooks add them from the start with good results!
Do I have to brown the beef first? For best flavor and texture, yes. Browning adds depth and ensures the meat is fully cooked.
Can I use fresh tomatoes instead of canned? Canned diced tomatoes work best for consistent liquid and flavor, but you can use about 3-4 cups chopped fresh tomatoes.
What size slow cooker do I need? A 3-quart or larger slow cooker works perfectly. For a 6-quart, consider doubling the recipe.
Can I cook this on the stovetop instead? Yes! Simmer in a large pot for 30-40 minutes until potatoes are tender, then add beans and cheese.
Is this spicy? No, it’s mild! The small amount of chili powder adds flavor without heat. Add more for spiciness or omit entirely.
