What You’ll Need (Ingredient Highlights)

Pro Tips Before You Start

Slice potatoes thinly and evenly so they cook through properly.

Drain your beef well after browning to avoid excess grease.

Use a mandoline slicer for quicker, uniform potato slices.

For extra depth, try adding a dash of smoked paprika or cumin.

If your slow cooker runs hot, check doneness after 5 hours on low.

How to Make Slow Cooker Cowboy Casserole

Step 1:

In a large skillet, cook 1 pound of ground beef with 1 chopped onion and 3 minced garlic cloves over medium heat.

Sauté until beef is browned and onions are soft. Drain excess fat.

Step 2:

Transfer beef mixture to your slow cooker. Stir in:

1 can cream of mushroom soup (10.75 oz)

1/2 cup milk

1 can kidney beans (15 oz, drained and rinsed)

1 can diced tomatoes with green chilies (14.5 oz)

1 cup frozen corn

1 tsp chili powder

1/2 tsp salt

1/4 tsp black pepper

Step 3:

Add 4 cups sliced potatoes (about 1.5 lbs) to the slow cooker.

Mix gently until the potatoes are well coated with the beef and sauce.

Step 4:

Cover and cook on low for 6–7 hours or high for 3–4 hours, until potatoes are tender.

Step 5:

In the final 20 minutes, sprinkle 1 cup shredded cheese on top and cover.

Let it melt, then serve hot.

What to Serve It With

Fresh green salad with a tangy vinaigrette

Homemade cornbread or dinner rolls

Steamed green beans or roasted broccoli

A dollop of sour cream or hot sauce on top

Iced tea or lemonade for a refreshing drink

Variations / Substitutions

Make it spicy – Add jalapeños or chipotle chili powder.

Use turkey or chicken – Swap out the beef for leaner options.

Add more veggies – Try bell peppers, mushrooms, or spinach.

Make it vegetarian – Use plant-based meat and extra beans.

Swap the cheese – Pepper jack or Colby blend adds a twist.

Storage & Leftovers

Refrigerator:
Store leftovers in an airtight container for up to 4 days.

Freezer:
Freeze in individual portions for up to 2 months.

Thaw overnight in the fridge.

Reheat:
Warm in the microwave or stovetop with a splash of broth or milk to loosen the sauce.

FAQs

Can I make this ahead of time?
Yes! Prep everything the night before and store in the fridge.

Start the slow cooker in the morning.

Can I use canned potatoes?
Fresh is best, but canned sliced potatoes can be used in a pinch—add them halfway through cooking.

What kind of cheese works best?
Cheddar, Colby Jack, or Monterey Jack all melt beautifully.

Do I have to brown the beef first?
Yes, it improves the flavor and texture.

Adding raw beef may make the dish greasy.

Can I double the recipe?
Yes, but use an 8-quart slow cooker and increase cooking time slightly.

What if I don’t have cream of mushroom soup?
Use cream of chicken or a homemade white sauce instead.

Is this recipe gluten-free?
Use gluten-free cream soup and double-check all canned ingredients to make it gluten-free.
