Ingredients

3–4 cups diced potatoes (Yukon gold or russet)
1 large onion, diced
3 cloves garlic, minced
2 cups shredded sharp cheddar cheese
1 cup shredded mozzarella (optional for extra melt)
1 cup beef broth
1 cup heavy cream or half-and-half

1 teaspoon garlic powder

Instructions

How to Make Slow Cooker Steak and Cheddar Potato Casserole

Prepare the slow cooker.
Lightly grease the inside of the crock with butter or nonstick spray.
Layer the potatoes first.
Add the diced potatoes to the bottom of the slow cooker. This helps them cook evenly.
Add the steak.
Arrange the cubed steak over the potatoes.
Season generously.
Sprinkle salt, pepper, smoked paprika, garlic powder, onion powder, dried thyme, and dried parsley evenly over the steak and potatoes.
Add onions and garlic.
Spread diced onions and minced garlic over the top for aromatic flavor.
Pour in the broth.
Add the beef broth, which helps tenderize the steak and cook the potatoes.
Add butter and cream.
Dot the butter over the mixture and pour in the heavy cream for richness.
Slow cook.
Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until steak is tender and potatoes are soft.
Add the cheese.
Stir in cheddar cheese (and mozzarella, if using). Cover again for 10–15 minutes until melted.
Serve warm.
Garnish with fresh parsley or green onions and enjoy.

Tips for Success

Use starchy potatoes for creaminess.
Yukon gold potatoes hold their shape well while still turning soft and buttery.

Don’t add the cheese too early.
Adding cheese at the beginning may cause separation. Stir it in at the end for a smooth finish.

Choose the right cut of steak.
Chuck roast, stew beef, or round steak all work beautifully.

Avoid over-salting before cooking.
Flavors concentrate in a slow cooker—start mild and adjust later.

Variations

1. Loaded Baked Potato Twist

Add cooked bacon, green onions, and extra cheddar at the end.

2. Veggie-Packed Version

Stir in peas, carrots, corn, or mushrooms during the last hour of cooking.

3. Spicy Variation

Add diced jalapeños or a pinch of cayenne pepper.

4. Cream Cheese Upgrade

Add 4 oz softened cream cheese right before the cheddar for a thicker, creamier sauce.

Serving Suggestions

Serve with crusty bread or garlic toast

Spoon leftovers into tortillas for a cheesy steak wrap
