Ingredients:
2½ to 3 pounds russet or Yukon Gold potatoes, thinly sliced
1 jar (15–16 oz) Alfredo sauce
2 cups shredded cheddar cheese, divided
1 cup shredded mozzarella cheese
½ cup grated Parmesan cheese
Salt and black pepper, to taste
Nonstick spray or butter for greasing the slow cooker
Directions:
Lightly grease the slow cooker to prevent sticking and make cleanup easier. Slice the potatoes evenly so they cook at the same rate. Season the potatoes lightly with salt and pepper, keeping in mind the Alfredo sauce and cheeses already contain salt.
Layer half of the sliced potatoes in the slow cooker, then sprinkle with half of the cheddar and mozzarella. Add the remaining potatoes, top with the rest of the cheddar and mozzarella, and finish with the Parmesan cheese. Slowly pour the Alfredo sauce evenly over the layers, allowing it to seep between the potatoes.
Gently press the mixture down to help distribute the sauce without crushing the potatoes. Cover and cook on LOW for 6–7 hours or on HIGH for 3–4 hours, until the potatoes are tender and the sauce is bubbling. Let rest for 10–15 minutes before serving to allow the casserole to thicken.
Serving Ideas:
This cheesy Alfredo potato casserole pairs beautifully with roasted chicken, grilled sausage, pork chops, or a fresh green salad. It also works well as a hearty vegetarian dish alongside roasted vegetables or steamed greens.
Variations & Tips:
Use garlic or roasted-garlic Alfredo sauce for extra flavor
Swap cheddar for an Italian cheese blend for a more classic Alfredo taste
Add peas, bell peppers, or spinach for color and nutrition
For a golden top, transfer to a baking dish, sprinkle with extra cheese, and broil briefly
