What Kind of Steak Should I Use for This Casserole?

Look for a cut that’s both flavorful and holds up well in slow cooking. Sirloin, chuck steak, or even skirt steak are great choices. These cuts tenderize beautifully over low heat and become fork-tender by the time dinner rolls around. Make sure to trim excess fat and cut the meat into bite-sized pieces for the best texture.

How To Make the Slow Cooker Steak and Cheddar Potato Casserole

Step 1: Sear the Steak for Extra Flavor

Start by seasoning your steak cubes with salt, pepper, and paprika. In a hot skillet, sear the meat in batches until browned on all sides. This step locks in flavor and adds a nice crust that carries over into the final dish.

Step 2: Sauté the Aromatics

In the same skillet, melt a bit of butter and sauté the chopped onions and minced garlic until translucent. This creates a fragrant base that enriches the slow cooker mixture.

Step 3: Layer the Ingredients in the Slow Cooker

Grease the inside of your slow cooker with butter or cooking spray. Add a layer of sliced potatoes, then some seared steak, sautéed onions, and a sprinkle of cheese. Repeat layers until all ingredients are used.

Step 4: Add the Creamy Base

In a mixing bowl, combine the cream of mushroom soup, sour cream, and beef broth. Stir well and pour this mixture evenly over the layered ingredients in the slow cooker.

Step 5: Slow Cook to Perfection

Cover the slow cooker and cook on LOW for 6-8 hours or on HIGH for 3-4 hours. The potatoes should be tender, and the steak should be easily shredded with a fork.

Step 6: Finish with a Cheddar Blanket

About 15 minutes before serving, sprinkle the remaining shredded cheddar cheese over the top and cover. Let it melt into a gooey, golden topping that makes this casserole irresistible.

Frequently Asked Questions

Can I use frozen steak?

Yes, but make sure to thaw it fully and pat it dry before searing to avoid excess moisture and ensure proper browning.

Can I substitute cheddar cheese with another type?

Absolutely! Monterey Jack, Colby, or even a smoked gouda would complement the flavors nicely.

How do I prevent the potatoes from getting mushy?

Use starchy potatoes like Russet or Yukon Gold and avoid overcooking. Keeping them in thicker slices also helps them hold their shape.

Can I prep this ahead of time?

Yes! You can prep all the ingredients the night before and refrigerate. In the morning, just pour everything into the slow cooker and start cooking.

What if I don’t have cream of mushroom soup?

You can substitute it with cream of chicken or a homemade white sauce made with butter, flour, and milk.
