- 1/2 teaspoon black pepper: Adds a gentle, spicy kick for complexity.
- 1/2 teaspoon paprika: Brings smokiness and a vibrant color that makes the dish irresistible.
- 1/2 teaspoon dried thyme: Offers an earthy herbal note to complement the beef and potatoes beautifully.
- 1 cup sour cream: Infuses creaminess and a subtle tang that transforms this casserole into something velvety and indulgent.
- 1/2 cup milk: Helps create the perfect creamy sauce consistency.
- 2 cups shredded sharp cheddar cheese: Melts into luscious pockets of cheesy goodness that crown the dish.
- 1 tablespoon olive oil: For searing the steak, locking in flavor and creating a delightful caramelized crust.

How to Make Slow Cooker Steak and Cheddar Potato Casserole Recipe
Step 1: Sear the Steak
Begin by heating olive oil in a large skillet over medium-high heat. Sear the bite-sized sirloin steak pieces for 2 to 3 minutes until they’re beautifully browned on the outside. Don’t worry if they’re not fully cooked yet; this step locks in juices and adds that irresistible, savory crust that highlights great steak flavor.
Step 2: Combine Main Ingredients in the Slow Cooker
Gently transfer the seared steak to a greased slow cooker. Add diced potatoes, finely chopped onion, minced garlic, salt, black pepper, paprika, and dried thyme. These form the hearty, seasoned base of your casserole and ensure every bite bursts with flavor.
Step 3: Prepare and Add the Creamy Mixture
In a small bowl, whisk together the sour cream and milk until smooth. Pour this creamy blend evenly over the steak and vegetable mixture in the slow cooker. This will become the luscious sauce that brings everything together while cooking.
Step 4: Set to Slow Cook
Cover the slow cooker and cook on low for 6 to 7 hours or on high for 3 to 4 hours. The slow heat tenderizes the potatoes and steak, melding the flavors into a comforting, cohesive dish. You’ll know it’s ready once the potatoes are tender to the fork.
Step 5: Add the Cheese Topping
About 20 minutes before serving, sprinkle the shredded sharp cheddar cheese evenly over the casserole’s surface. Cover the slow cooker again and let the cheese melt thoroughly, creating a rich, gooey, golden crust that’s impossible to resist.
Step 6: Garnish and Serve
Before serving, sprinkle chopped green onions or fresh parsley on top to add a fresh burst of color and a mild, lively flavor that brightens each mouthful of this hearty dish.

Garnishes
A simple garnish of freshly chopped green onions or parsley can elevate the dish instantly. The pop of green not only makes the casserole look inviting and vibrant but also adds a subtle freshness that beautifully contrasts the cheesy richness.
Side Dishes
This dish is wonderfully standalone, but if you want to round out your meal, consider serving it alongside a crisp green salad with a tangy vinaigrette or some roasted vegetables. These lighter sides balance the richness without stealing the spotlight from the casserole.
Creative Ways to Present
For a fun twist, try serving individual portions in small ramekins or cast iron skillets right from the slow cooker. You could even top it with a dollop of sour cream or a spoonful of your favorite salsa for an extra burst of flavor and flair at the table.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer leftover casserole into an airtight container and store it in the refrigerator. It will stay fresh and delicious for up to 3 days, making for an easy grab-and-go meal or a quick reheat for lunch the next day.
Freezing
This Slow Cooker Steak and Cheddar Potato Casserole Recipe freezes well. Portion it into freezer-safe containers or bags and freeze for up to 2 months. When you’re ready, thaw overnight in the fridge and reheat gently to maintain its creamy texture and hearty flavors.
Reheating
To reheat, use a microwave or oven. For the best results, reheat covered in a 350°F oven until warmed through, about 20 to 30 minutes. This helps the cheese melt evenly and prevents the casserole from drying out.
FAQs
Can I use a different cut of steak for this recipe?
Absolutely! While sirloin is preferred for its tenderness and flavor, you can substitute with ribeye or even flank steak. Just be sure to cut it into small, bite-sized pieces for even cooking and tenderness.
Can I prepare this casserole without a slow cooker?
Yes, you can adapt the recipe to the oven. Layer the ingredients in a baking dish, cover tightly with foil, and bake at 350°F for about 1.5 hours or until potatoes are tender. Add cheese topping near the end to melt.
Is there a way to make this recipe dairy-free?
You can substitute the sour cream and milk with dairy-free versions like coconut milk or almond-based sour cream alternatives. Use a dairy-free cheese or omit it if needed, keeping in mind the flavor profile will change.
What type of potatoes work best?
Russet potatoes are great for their fluffy texture, but Yukon Gold potatoes add creaminess and buttery flavor. Both work wonderfully depending on whether you prefer a more rustic feel or a smoother finish.
Can I add vegetables to the casserole?
Definitely! Diced bell peppers, mushrooms, or spinach make excellent additions that boost the nutritional value and add delicious layers of flavor without overpowering the classic taste of the casserole.
