Why You’ll Love This Recipe

I love this casserole because it’s incredibly easy to prepare and full of flavor. The slow cooker does all the work, turning simple ingredients into a cheesy, savory, fork-tender meal. With juicy steak, soft potatoes, and sharp cheddar in every bite, it’s a comforting dinner that’s perfect for cooler weather, family dinners, or meal prepping for the week. It’s like a loaded baked potato and steak dinner rolled into one dish.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

  • Steak (sirloin or chuck), cut into bite-sized pieces

  • Potatoes (Yukon gold or russet), peeled and sliced thin

  • Onion, chopped

  • Garlic, minced

  • Shredded cheddar cheese

  • Sour cream or cream cheese

  • Milk or heavy cream

  • Butter

  • Salt and pepper

  • Paprika or smoked paprika

  • Optional: green onions or parsley for garnish

Directions

  1. I start by seasoning the steak with salt, pepper, and paprika.

  2. In a slow cooker, I layer half of the sliced potatoes, followed by half the onions and steak pieces.

  3. I sprinkle on a layer of cheddar, then repeat the layers with the remaining ingredients.

  4. In a bowl, I mix sour cream, milk, garlic, and melted butter. I pour this mixture evenly over the layers in the slow cooker.

  5. I cover and cook on low for 6–7 hours or on high for 3–4 hours, until the potatoes are tender and the steak is cooked through.

  6. In the last 15–20 minutes, I sprinkle a final layer of cheddar on top, cover again, and let it melt.

  7. I garnish with chopped green onions or parsley and serve warm.

Servings and timing

This recipe makes about 6 servings and takes 6–7 hours on low or 3–4 hours on high to cook, with just 15 minutes of prep time.

Variations

  • I sometimes add chopped bell peppers or mushrooms for extra veggies.

  • Swapping the steak for cooked ground beef or shredded chicken works well too.

  • I’ve used Monterey Jack or a cheddar blend for a different cheese flavor.

  • A sprinkle of crispy fried onions on top adds crunch and even more flavor.

Storage/Reheating

I store leftovers in an airtight container in the fridge for up to 4 days. To reheat, I warm it in the microwave or oven at 350°F until hot. It also freezes well—just cool it completely, wrap tightly, and store for up to 2 months. I thaw it in the fridge overnight and reheat as usual.

FAQs

What type of steak works best?

I prefer sirloin or chuck steak for this recipe. Sirloin is leaner, while chuck gives a richer, more tender bite after slow cooking.

Can I use frozen potatoes?

Yes, I’ve used frozen hash browns or sliced potatoes. I just adjust the cook time slightly and reduce added liquid since frozen potatoes release moisture.

Do I need to brown the steak first?

No, I usually add it raw, but searing it first adds extra flavor if I have time.

Can I make this recipe dairy-free?

Yes, I use dairy-free cheese and sour cream alternatives. Unsweetened plant-based cream or broth also works well in place of milk.

Is this casserole gluten-free?

It is, as long as all ingredients (like cheese and sour cream) are labeled gluten-free.

Conclusion

Slow Cooker Steak and Cheddar Potato Casserole is a warm, cheesy, and hearty meal I rely on when I want a hands-off dinner that feels like comfort food. It’s easy to make, always filling, and perfect for feeding a hungry family or prepping a few days’ worth of meals. With simple layers and bold flavors, this recipe is a cozy classic I’ll keep coming back to.
