1 tsp garlic powder
1 tsp onion powder
1 tsp smoked paprika
1 medium onion, chopped
3 garlic cloves, minced
4 medium russet potatoes, thinly sliced
1 ½ cups shredded sharp cheddar cheese (reserve ½ cup for topping)
1 cup beef broth
1 cup heavy cream (or half-and-half for lighter)

2 tbsp butter
2 tbsp fresh parsley, chopped (for garnish)

Timing

Cook time: 6–7 hours on LOW or 3–4 hours on HIGH
Total time: ~7 hours (slow cooked perfection)

Step-by-Step Instructions

Step 1: Prep the Steak

Season steak cubes with salt, pepper, garlic powder, onion powder, and smoked paprika.

Step 2: Sear for Flavor

In a skillet, heat olive oil and sear steak on high heat until browned (2–3 minutes). This locks in flavor but is optional.

Step 3: Layer Ingredients

In your slow cooker, layer half of the sliced potatoes, followed by half the onions and garlic. Add seared steak and sprinkle with ½ the cheddar cheese. Repeat layers with remaining potatoes, onions, and garlic.

Step 4: Make the Sauce

In a saucepan, melt butter, whisk in flour, then add beef broth and cream. Cook until slightly thickened (3–4 minutes). Pour sauce over the layered casserole.

Step 5: Slow Cook

Cover and cook on LOW for 6–7 hours or HIGH for 3–4 hours, until potatoes are tender and steak is melt-in-your-mouth.

Step 6: Finish with Cheese

Sprinkle remaining cheddar on top. Cover until melted. Garnish with parsley before serving.
