My sister-in-law begged for this recipe after Easter dinner. It only takes 4 ingredients and turns out perfectly creamy every time

This Slow Cooker 4-Ingredient Cheesy Scalloped Potatoes recipe is an easy, no-fuss twist on a classic comfort side. Using dry onion soup mix means no chopping or measuring extra seasonings—the mix brings all the savory flavor you need. As the potatoes cook, their natural starch blends with the heavy cream to create a rich, smooth sauce that feels extra indulgent without any added steps.

Slow Cooker Cheesy Scalloped Potatoes

Ingredients:
Potatoes (Russet or Yukon Gold) – 3 lbs
Sharp cheddar cheese (shredded) – 3 cups
Heavy cream – 2 cups
Dry onion soup mix – 1 (1 oz) packet

How To Make Slow Cooker Cheesy Scalloped Potatoes:

Step 1: Make the Cream Mixture
In a medium bowl, whisk together the heavy cream and dry onion soup mix until fully combined. Let it sit for a few minutes while you prepare the potatoes so the dried onions can soften.

Step 2: Prep and Layer
Peel the potatoes and slice them into thin rounds (about 1/8 inch). Lightly grease a 5–6 quart slow cooker. Add a layer of potatoes, sprinkle with about 3/4 cup cheese, and pour over some of the cream mixture. Repeat the layers until everything is used, ending with cheese on top.

Step 3: Cook Low and Slow
Cover and cook on HIGH for about 3½–4½ hours or on LOW for 6–7 hours. The dish is ready when the potatoes are tender and the sauce is thick and bubbling.

Step 4: Add the Final Cheese
If you saved some cheese, sprinkle it over the top during the last 20–30 minutes so it melts nicely.

Step 5: Let It Rest
Turn the slow cooker to WARM and let the potatoes sit for 10–15 minutes before serving. This helps the sauce thicken and cling to the potatoes for the perfect texture.
