  • Spice it Up: Add some diced jalapeños or a splash of hot sauce for those of you who enjoy a little heat.
  • Cheese Variety: Mix it up with pepper jack, or even a dollop of cream cheese for a creamier texture.

Let’s Get Cooking: Slow Cooker Beef and Potato Casserole Recipe

Ingredients

  • 1 lb ground beef
  • 3-4 medium potatoes, peeled and cubed
  • 1 cup black beans (canned, drained and rinsed)
  • 1 cup corn kernels (fresh, frozen, or canned and drained)
  • 1 can (14.5 oz) diced tomatoes
  • 1 small onion, finely chopped
  • 2-3 cloves garlic, minced
  • 1 cup beef broth (optional, for moisture)
  • 1-2 tsp chili powder
  • 1 tsp ground cumin
  • Salt and black pepper to taste
  • 1-2 cups shredded cheddar cheese (or mixed cheddar and Monterey Jack)
  • Fresh parsley or cilantro, chopped for garnish
  • 1 tbsp olive oil or cooking oil

Serves 4–6 people

Standard portions → 4 servings
Slightly smaller portions → up to 6 servings

Instructions

  1. Start off by heating the olive oil in a skillet over medium heat. Add the chopped onion and minced garlic, and sauté for about 3-4 minutes until they’re softened and fragrant. Trust me, your kitchen will smell amazing!
  2. Next, add the ground beef to the skillet. Cook it until it’s browned and crumbly. Make sure to break up any clumps you see, and when it’s ready, drain any excess fat.
  3. Now, it’s time to spice things up! Stir in the chili powder, cumin, salt, and black pepper, letting the spices cook for another minute so they really get infused in the beef.
  4. Transfer the seasoned beef mixture into your slow cooker. It’s getting good, right?
  5. Next, add the cubed potatoes, black beans, corn kernels, and diced tomatoes into the slow cooker and stir gently to mix everything evenly.
  6. If you’re using beef broth, pour it in now; this will keep your casserole moist and yummy.
  7. Cover the slow cooker and set it to cook on low for 6 to 8 hours or on high for 3 to 4 hours. The best part? Just let it do its magic until the potatoes are nice and tender!
  8. About 20-30 minutes before you’re ready to eat, sprinkle the shredded cheese evenly over the casserole. Cover it back up and let the cheese melt into a gooey, delicious layer.
  9. Finally, once it’s done, garnish with freshly chopped parsley or cilantro. Serve hot, right from the slow cooker, and watch everyone dig in with big smiles!

Practical & Valuable Tips

  • If you prefer firmer potatoes, consider cutting them a bit larger or adding them halfway through the cooking time.
  • To store leftovers, just place them in an airtight container in the fridge for up to 3-4 days. Reheat gently in the microwave or on the stove.
  • You can freeze this casserole too! Just make sure it cools completely before transferring it to a freezer-safe container.

Equipment Needed

Let’s make sure you have everything you need before you start:

  • A large skillet for browning the beef
  • A slow cooker (of course!)
  • A cutting board and knife for chopping veggies
  • A spatula or wooden spoon for mixing
  • A measuring cup and spoons for accuracy

Frequently Asked Questions

  1. Can I use frozen potatoes? While fresh potatoes work best, you can use frozen cubed potatoes. Just note that they might release more moisture.
  2. What can I serve with this casserole? It’s great on its own, but a fresh side salad or some crusty bread would complement it beautifully!
  3. Can I make this vegetarian? Absolutely! Substitute the ground beef with your choice of lentils or extra beans and use vegetable broth instead of beef broth.
  4. How do I know if it’s done? The potatoes should be fork-tender, and the flavors should meld beautifully.
  5. Can I leave it on low overnight? I recommend no more than 8 hours on low to avoid overcooking the potatoes, but it’s best to cook it when you can monitor it!
