Ingredients You’ll Need

To make this Slow Cooker Cheese and Cheddar Potato Casserole, you’ll need the following ingredients:

  • Russet or Yukon Gold potatoes (thinly sliced)

  • Shredded cheddar cheese (sharp or mild depending on preference)

  • Cream cheese or heavy cream

  • Sour cream or Greek yogurt (for tang)

  • Butter (unsalted, melted)

  • Onion (finely chopped)

  • Garlic powder

  • Salt and pepper

  • Optional toppings: chives, parsley, bacon bits, or breadcrumbs

How to Make Slow Cooker Cheese and Cheddar Potato Casserole

Step 1: Prepare the Potatoes

Wash, peel, and thinly slice the potatoes evenly using a mandoline or sharp knife. Uniform slices ensure even cooking.

Step 2: Mix the Cheese Sauce

In a large bowl, combine shredded cheddar cheese, cream cheese (or heavy cream), sour cream, melted butter, garlic powder, salt, and pepper. Mix until well combined.

Step 3: Layer the Ingredients

Grease the inside of your slow cooker with butter or non-stick spray. Begin by layering a portion of the sliced potatoes at the bottom. Spread some of the cheese mixture over the potatoes. Repeat layers until all the ingredients are used, finishing with a generous sprinkle of cheese on top.

Step 4: Cook Slowly

Set your slow cooker to low and cook for about 5–6 hours or until the potatoes are fork-tender and the cheese sauce is bubbling. You can also cook on high for 3–4 hours if you’re short on time.

Step 5: Garnish and Serve

Once cooked, let the casserole sit for 10–15 minutes. Garnish with freshly chopped chives or parsley for added color and flavor. Serve hot as a main dish or a comforting side.

Tips for Best Results

  • Choose starchy potatoes like Russets for a softer texture, or Yukon Golds for a buttery consistency.

  • Slice potatoes evenly to ensure consistent cooking.

  • Avoid overcooking by checking the texture near the end of the cooking time.

  • Use freshly grated cheese for better melt and flavor—pre-shredded cheese may contain anti-caking agents.

  • Add a crispy topping by transferring the finished dish to a broiler-safe dish and broiling for a few minutes for a golden crust.

How to Store and Reheat

Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. To reheat, place the desired portion in the microwave or reheat in the oven at 350°F (175°C) until warmed through. If the casserole looks dry, stir in a small splash of cream or milk before reheating.

Variations and Add-ins

Feel free to customize this casserole to suit your taste:

  • Add protein: Mix in cooked bacon, ham, or ground sausage.

  • Spice it up: Add diced jalapeños or a pinch of cayenne pepper.

  • Make it vegetarian: Skip the meats and add more veggies like bell peppers or mushrooms.

  • Use different cheeses: Try Monterey Jack, mozzarella, or gouda for unique flavors.
