This dish tastes like something straight out of grandma’s kitchen — warm, cheesy, and made with love.

Ingredients You’ll Need

This recipe serves about 8 people, making it perfect for a big family dinner or gathering.

Here’s what you’ll need:

• 3 lbs Yukon gold potatoes (about 6 medium, sliced 1/8” thick)
• 1 onion, thinly sliced
• 3 cups whole milk
• 3 Tbsp heaping cornstarch
• 2 Tbsp prepared yellow mustard
• 2 ½ tsp salt
• ¾ tsp black pepper
• 8 oz white cheddar cheese, grated

Tip: If you love bolder flavor, try swapping half the cheddar for Gruyère or adding a touch of garlic powder to the sauce.

How to Make Crock Pot Scalloped Potatoes

Making scalloped potatoes slow cooker style is truly as simple as layering, mixing, and letting time do its magic.

Step 1: Prep the Slow Cooker

Spray the inside of your crock pot with oil or nonstick spray. You can also rub it lightly with butter for extra richness (and that nostalgic buttery aroma).

Step 2: Slice the Potatoes

Use a mandoline or sharp knife to get even, thin slices — about ⅛ inch thick. The thinner the slices, the creamier your scalloped potatoes will be.

Step 3: Layer the Ingredients

Layer ⅓ of the onions, potatoes, and cheese into the crock pot. Repeat this pattern twice, finishing with a beautiful layer of potatoes and cheese on top.

Sophia’s Tip: I like to season each layer lightly with a pinch of salt and pepper as I go — it keeps the flavor balanced throughout.

Step 4: Mix the Sauce

In a large measuring cup, whisk together the milk, cornstarch, yellow mustard, salt, and black pepper until smooth. This will be your creamy, cheesy base that thickens perfectly as it cooks.

Step 5: Pour and Cook

Pour the milk mixture evenly over all the layers. Cover and cook:

• On High for 3–4 hours, or
• On Low for 6–7 hours, until the potatoes are fork-tender and the sauce is thick and bubbly.

Your kitchen will smell incredible by hour two — it’s that slow-cooked goodness that makes the wait worth it.

Step 6: Rest Before Serving

Once done, unplug the slow cooker and let it rest for about 20 minutes. This helps the sauce thicken beautifully, so you get perfect, creamy slices instead of a runny mess.
