How to Make Crockpot Cheesesteak Potato Casserole
Step 1: Prepare the Slow Cooker
Lightly grease a 6-quart slow cooker with nonstick cooking spray.
Thaw the hash browns completely and pat them dry with paper towels so the casserole does not turn watery.
Step 2: Season the Steak
Pat the shaved steak dry.
Season it with the salt and pepper.
Cook the Steak and Vegetables
Step 3: Saute the Vegetables
Heat the olive oil in a large skillet over medium-high heat.
Add the peppers, onions, and mushrooms, and cook for 5–7 minutes, until softened and lightly golden.
Add the garlic and cook for 30 seconds.
Step 4: Cook the Steak
Push the vegetables to one side of the skillet and add the steak.
Cook for 2–3 minutes, until it is no longer pink, then stir in the Worcestershire sauce.
Remove from the heat and set aside.
Make the Cheese Sauce
Step 5: Whisk the Sauce
In a large bowl, whisk together the cheddar cheese soup, sour cream, beef broth, and softened cream cheese until smooth.
Stir in the 1 cup of shredded mozzarella.
Step 6: Combine the Potatoes
Add the thawed hash browns, garlic powder, onion powder, salt, and pepper to the bowl.
Stir until the potatoes are evenly coated.
Assemble the Casserole
Step 7: Add the Potatoes
Spread half of the potato mixture in an even layer in the bottom of the slow cooker.
Step 8: Add the Steak
Top with half of the steak and vegetable mixture.
Lay 4 slices of provolone over the top.
Step 9: Repeat the Layers
Add the remaining potato mixture, then the remaining steak and vegetables.
Do not add the remaining cheese yet.
Cook the Casserole
Step 10: Cook
Cover and cook on low for 4–5 hours or on high for 2½–3 hours.
The potatoes should be tender and the edges should be bubbling.
Step 11: Add the Cheese Topping
Arrange the remaining provolone slices over the top and sprinkle with the remaining mozzarella.
Cover and cook for 10–15 minutes, until the cheese is melted.
Step 12: Rest
Turn off the slow cooker and let the casserole rest, covered, for 10 minutes.
This helps the sauce thicken so each portion holds together.
Step 13: Garnish and Serve
Top with parsley, green onions, or cracked black pepper.
Serve warm.
The Best Steak to Use
Choose a tender cut that cooks quickly and slices thinly.
Good options include:
- Shaved ribeye
- Thinly sliced sirloin
- Flank steak, sliced against the grain
- Shaved beef from the deli counter
- Leftover roast beef, thinly sliced
- Frozen shaved steak, thawed
Ribeye has the best marbling and gives the richest cheesesteak flavor.
How to Prevent a Watery Casserole
- Thaw the hash browns completely
- Pat the potatoes dry
- Cook the vegetables before adding them
- Drain any extra liquid from the steak
- Use full-fat dairy
- Wipe the lid condensation once during cooking
- Rest the casserole before serving
Slow cookers trap steam, so removing excess moisture early helps keep the sauce creamy and thick.
Can I Use Diced or Cubed Hash Browns?
Yes. Frozen diced or southern-style hash browns work well in this recipe.
Thaw them and pat them dry. Cubed potatoes will hold their shape better, while shredded hash browns create a softer, creamier texture.
Can I Use Fresh Potatoes?
Yes. Use about 2½ pounds of peeled, thinly sliced or diced Yukon Gold potatoes.
Fresh potatoes need more cooking time, so plan on 6–7 hours on low and make sure they are fork-tender before adding the topping.
Delicious Variations
Spicy Cheesesteak Casserole
Add sliced jalapeños or banana peppers and use pepper Jack in place of provolone.
Chicken Cheesesteak Potato Casserole
Replace the steak with thinly sliced chicken breast, cooked until no longer pink.
White Cheddar Cheesesteak Casserole
Use white cheddar soup and white cheddar cheese for a sharper flavor.
Loaded Cheesesteak Potato Casserole
Add crumbled cooked bacon and top with chopped chives.
Cheesesteak Breakfast Casserole
Serve the casserole topped with fried or poached eggs for a hearty brunch.
Can I Make It Ahead?
Yes. Cook the steak and vegetables up to one day in advance and refrigerate them in an airtight container.
Assemble the casserole the next day, adding 30–60 minutes to the cooking time if the ingredients are cold.
Add the cheese topping just before the end of cooking for the best melted texture.
Storage
Store leftovers in an airtight container in the refrigerator.
Refrigerate for up to four days.
Reheat in the microwave, oven, or air fryer until hot throughout, adding a splash of beef broth if needed.
Can You Freeze Crockpot Cheesesteak Potato Casserole?
Yes. Cool the casserole completely and transfer it to a freezer-safe container.
Freeze for up to two months.
Thaw overnight in the refrigerator and reheat until hot throughout. The texture may be slightly softer after freezing.
Frequently Asked Questions
Do I need to cook the steak first?
Yes. Shaved steak cooks quickly in a skillet and gains more flavor from browning.
Do I need to thaw the hash browns?
Yes. Thaw them completely and pat them dry. Frozen potatoes release extra water and can make the casserole soupy.
How do I know when it’s done?
The potatoes should be tender throughout and the sauce should bubble around the edges.
Why is my casserole too thin?
The vegetables or potatoes may have released extra liquid. Cook with the lid slightly ajar for the last 30 minutes, or let it rest uncovered for 10 minutes.
Can I use a smaller slow cooker?
Yes. A 4-quart slow cooker works if you reduce the recipe by about one-third.
Can I use Swiss or American cheese?
Yes. Swiss, American, and white cheddar all work well in place of provolone.
Can I leave out the mushrooms?
Yes. The casserole is still delicious with only peppers and onions.
Pro Tips
Thaw and dry the hash browns well so the casserole stays creamy.
Sear the steak briefly over high heat for the best flavor.
Slice the peppers and onions thinly so they blend smoothly into each bite.
Let the casserole rest before serving so the cheese sauce can set.
