How to Make Slow Cooker Steak and Cheddar Potato Casserole

Step 1: Season the Beef

Start by placing your cubed beef into a bowl. Sprinkle with paprika, thyme, salt, and pepper. Toss well so every piece is evenly coated. This step builds the base flavor of the entire dish, so don’t rush it.

Step 2: Layer the Vegetables

Add the diced potatoes and onions into the bottom of your slow cooker. This creates a flavorful base that will soak up all the juices from the beef as it cooks.

Step 3: Add the Steak

Place the seasoned beef on top of the potatoes and onions. Try to spread it evenly so everything cooks at the same rate.

Step 4: Mix the Creamy Sauce

In a bowl, combine beef broth, sour cream, and minced garlic. Stir until smooth, then pour this mixture evenly over everything in the slow cooker. This is what creates that rich, creamy texture.

Step 5: Slow Cook to Perfection

Cover and cook on low for 7–8 hours or on high for 4–5 hours. The beef should be tender and the potatoes soft when done. Avoid lifting the lid too often so the heat stays consistent.

Step 6: Add the Cheese

About 15 minutes before serving, sprinkle shredded cheddar cheese over the top. Cover again and let it melt into a gooey, delicious layer.

Step 7: Serve and Enjoy

Spoon into bowls and garnish with fresh parsley or chives if desired. Serve hot and enjoy the creamy, cheesy comfort in every bite.

Tips for Success

• Use chuck steak for the most tender, flavorful results after slow cooking
• Cut potatoes evenly so they cook at the same rate
• Don’t skip seasoning the beef—it builds deep flavor throughout the dish

• For extra richness, stir a little more sour cream in right before serving

Equipment Needed

FAQs

Can I use a different cut of beef?

Yes, sirloin or ribeye can work, but chuck is best for tenderness in slow cooking.

Can I make this ahead of time?

Absolutely. You can prep all ingredients the night before and refrigerate them, then start cooking the next day.

Can I freeze this casserole?

Yes, it freezes well. Store in an airtight container for up to 2 months.

Can I use milk instead of sour cream?

You can, but the sauce will be less thick and creamy. Greek yogurt is a better substitute.

How do I make it thicker?

Let it sit uncovered for 10–15 minutes after cooking, or stir in a small amount of cornstarch slurry.
