Ingredients:
- 1 lb ground beef
- 1 can (15 oz) black beans, drained and rinsed
- 1 can (15 oz) corn, drained
- 1 can (10 oz) diced tomatoes with green chilies
- 2 cups frozen tater tots
- 1 cup shredded cheddar cheese
- 1 onion, chopped
- 2 cloves garlic, minced
- 1 tablespoon chili powder
- Salt and pepper to taste
How to make Slow Cooker Cowboy Casserole
Step 1: Prep
Start by browning the ground beef. Heat a skillet over medium-high, then add the chopped onion and minced garlic.
Brown the beef until it’s no longer pink and the onion is translucent. Drain any excess fat; this keeps the dish from being greasy.
Pro Tip: You’ll know it’s ready when the beef is fully browned, and the onions start to soften.
Step 2: Mixing
Transfer the beef mixture to your slow cooker. Add in the rinsed black beans, drained corn, and diced tomatoes with green chilies.
Sprinkle in the chili powder, salt, and pepper. Give everything a good stir to combine.
Pro Tip: Making sure to mix well helps distribute all the flavors evenly.
Step 3: Tater Tot Layer
Now, it’s time for the fun part! Arrange the frozen tater tots in a single layer on top of the beef mixture.
Don’t worry about perfection; just cover as much surface area as possible.
Pro Tip: The more tater tots, the crispier the topping!
Step 4: Cooking
Cover the slow cooker and let it work its magic. Cook on low for 6–8 hours or on high for 3–4 hours.
The longer it cooks, the more flavors meld together.
Pro Tip: Check for doneness by ensuring the meat mixture is bubbling and heated through.
Step 5: Cheese It Up
About 30 minutes before you’re ready to serve, sprinkle shredded cheddar cheese over the tater tots.
Cover the slow cooker again and allow the cheese to melt into gooey perfection.
Step 6: Serve
Scoop portions onto plates, making sure everyone gets some beef, beans, and cheesy tots on top.
Pro Tip: Serve with a dollop of sour cream or salsa for an extra flavor kick!
