Ingredients For Slow Cooker Steak and Cheddar Potato Casserole

Here’s everything you’ll need to make this deliciously cheesy comfort dish:

For the Casserole:

1 ½ lbs steak (sirloin or ribeye), cubed into bite-sized pieces
4 large potatoes (Russet or Yukon Gold), thinly sliced
2 cups cheddar cheese (sharp, freshly grated for optimal melting)
1 cup heavy cream (adds richness to the casserole)
1 cup beef broth (creates a savory base and keeps the dish moist)
1 medium onion, finely diced (for sweetness and texture)
2 cloves garlic, minced (to enhance the flavor profile)
2 tbsp butter (for searing steak and layering flavors)

For Seasonings and Garnish:

1 tsp smoked paprika (adds a smoky depth)
½ tsp black pepper (for subtle heat)
1 tsp salt (adjust to taste)
Fresh parsley or green onions (optional garnish for a pop of color and flavor)

How to Make Slow Cooker Steak and Cheddar Potato Casserole

Step 1: Sear the Steak

Grab your skillet and heat it over medium-high. Melt the butter, then add the cubed steak. Sprinkle on the salt, black pepper, and smoked paprika. Sear the steak until it’s nicely browned on all sides—this step is key for building rich, meaty flavor.

Remove the steak from the heat and set aside. (Try not to sneak too many taste tests—I’m speaking from personal experience here!)

Step 2: Layer the Ingredients

Time for a little edible architecture! In your slow cooker:

Spread half the sliced potatoes across the bottom.
Top with half the diced onions and minced garlic.
Add your glorious seared steak in an even layer.
Finish with the remaining potatoes, onions, and garlic.

Step 3: Add Liquids

Pour the beef broth and heavy cream evenly over the layered ingredients. If you’re feeling like an extra flavor boost, sprinkle on a pinch more salt and pepper.

Step 4: Cheese it Up

This is the best part! Sprinkle the entire casserole with your freshly grated cheddar cheese. It’ll melt into a luscious, cheesy layer that ties everything together.

Step 5: Cook

Cover your slow cooker and choose your adventure:

Low for 6-8 hours
High for 3-4 hours

Either way, you’ll end up with tender potatoes, juicy steak, and melted cheese perfection.

Step 6: Serve

Once cooked, garnish your casserole with freshly chopped parsley or green onions if you’d like a pop of color and brightness.

Scoop it onto plates, breathe in that incredible aroma, and enjoy!

Tips for the Best Slow Cooker Steak and Cheddar Potato Casserole

Thin potato slices are key. Thicker slices may take longer to soften, so aim for even, thin rounds.
Use sharp cheddar. It melts beautifully and adds a punch of flavor. Pre-shredded cheese works in a pinch, but freshly grated is worth it.
Adjust liquid if needed. If your casserole looks a little dry halfway through, add a splash more broth. If it’s too thin, leave the lid off for the last 30 minutes to thicken.
Experiment with different steaks. Ribeye is extra rich, while sirloin offers a leaner option without sacrificing flavor.

And if your sauce looks suspiciously thick? Don’t panic—that’s just extra comfort waiting to happen!
