There are some dishes that just scream comfort, and for me, scalloped potatoes are right at the top. But traditional recipes require babysitting a hot oven and standing over a roux. That's why I started making them in my crockpot—it frees up my hands and my oven for the main event.

Why You'll Love This Recipe
About the Ingredients
3 lbs (1.4 kg) russet potatoes, peeled and thinly sliced (about 1/8-inch thick)
Russets hold their shape well and give that classic fluffy texture. You can substitute Yukon Golds for a creamier bite; no need to peel if you like the skin.
1 medium yellow onion, finely chopped
Adds a subtle sweetness and depth. Shallots or leeks work great too—use about 1/2 cup.
2 cups (480 ml) heavy cream
For the richest sauce. You can swap half-and-half for a lighter version, or use whole milk with 1 tablespoon of melted butter stirred in for extra richness.
1 cup (240 ml) low-sodium chicken or vegetable broth
Keeps the sauce from being too heavy. Use vegetable broth for a vegetarian version.
3 cloves garlic, minced
Fresh garlic is best, but 1/2 teaspoon garlic powder works in a pinch.
2 cups (200 g) shredded sharp cheddar cheese, divided
Sharp cheddar gives a bold flavor. For a milder taste, use medium cheddar or Monterey Jack. You can also mix in Gruyère for extra nuttiness.
1/2 cup (50 g) grated Parmesan cheese
Adds a salty, savory kick. Pecorino Romano is a great substitute.
2 tablespoons (30 g) unsalted butter, cut into small pieces
Adds richness and helps the top brown nicely. You can use salted butter and reduce added salt.
1 teaspoon salt
Adjust to taste. If using salted broth, reduce to 1/2 teaspoon.
1/2 teaspoon black pepper
Freshly ground is best for flavor.
1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried)
Optional but adds a lovely herbaceous note. Rosemary or parsley also work.
Tips & Tricks
Slice potatoes uniformly
Use a mandoline or sharp knife to get even 1/8-inch slices so they cook evenly.
Don't skip the cream
The fat in the cream is essential for that luscious texture. If you use milk, expect a thinner sauce.
Layer evenly
Make sure potato slices are arranged in an even layer to ensure all cook at the same rate.
Keep an eye on the top
If the top isn't browned after the cooking time, you can broil the crockpot insert (if oven-safe) for 2-3 minutes, watching closely.
Pro Tips
Step-by-Step Instructions
1. Prep the Potatoes
Peel and thinly slice the potatoes using a mandoline or sharp knife. Place slices in a large bowl and cover with cold water to prevent browning while you prep the sauce.
2. Mix the Sauce
In a medium bowl, whisk together the heavy cream, broth, garlic, salt, pepper, and thyme. Set aside.
3. Layer the Potatoes
Grease the crockpot insert with butter or nonstick spray. Layer one-third of the potato slices, overlapping slightly. Sprinkle with one-third of the onions, one-third of the cheddar, and a few dots of butter. Repeat with two more layers, ending with the remaining cheese.
4. Pour the Sauce
Pour the cream mixture evenly over the layers. Gently press down with a spatula to ensure the sauce reaches all the layers.
5. Cook on Low
Cover and cook on LOW for 6-7 hours, or on HIGH for 3-4 hours, until the potatoes are fork-tender and the edges are bubbly. The internal temperature should reach at least 190°F (88°C) to ensure the starch is fully cooked.
6. Add Parmesan
During the last 30 minutes of cooking, sprinkle the Parmesan cheese over the top. Continue cooking uncovered (if possible) to allow the top to get slightly golden and crispy.
7. Rest and Serve
Turn off the crockpot and let the potatoes rest for 10 minutes. This helps the sauce thicken and makes serving easier. Garnish with fresh thyme if desired.
Delicious Variations
Add protein
Layer in cooked, crumbled bacon or diced ham for a heartier side that can double as a main.
Make it spicy
Add 1/2 teaspoon of smoked paprika or a pinch of cayenne to the sauce, and use pepper jack cheese instead of cheddar.
Try sweet potatoes
For a twist, use half sweet potatoes and half russets. The natural sweetness pairs beautifully with the creamy sauce.

Frequently Asked Questions
Q: Can I use milk instead of heavy cream?
Yes, you can use whole milk, but the sauce will be thinner and less creamy. To mimic the richness, stir in 2 tablespoons of melted butter per cup of milk.
Q: Why are my scalloped potatoes still hard in the middle?
This usually happens if the potatoes are sliced too thick or the crockpot is on low but not cooking long enough. Slice them thinly (1/8-inch) and cook until fork-tender—check at the 6-hour mark on low.
Q: Can I prepare this the night before?
Absolutely! Assemble everything in the crockpot insert, cover, and refrigerate overnight. In the morning, just place it in the slow cooker and cook as directed, adding 30 minutes to the cooking time.
Q: How do I prevent the top from becoming soggy?
To get a slightly crispy top, cook uncovered for the last 30 minutes. You can also broil the crockpot insert for 2-3 minutes if it's oven-safe, but watch it closely.
