Slow Cooker Cheesy Garlic Hasselback Potatoes

Prep Time: 15 minutes
Cook Time: 3½–4 hours on HIGH or 6–7 hours on LOW
Total Time: About 4 hours
Servings: 6–8

These slow-cooker Hasselback potatoes are tender in the center, buttery and garlicky throughout, with melted cheese covering the tops. The Hasselback technique uses thin cuts made almost all the way through the potato while keeping the bottom intact, allowing the garlic butter and cheese to work into the layers.

Ingredients

For the Potatoes:

6–8 medium Yukon Gold or Russet potatoes
4 tablespoons unsalted butter, melted
3 tablespoons olive oil
4–5 cloves garlic, finely minced
1 teaspoon Italian seasoning
1 teaspoon paprika
1 teaspoon salt
½ teaspoon black pepper

For the Cheese Topping:

1 cup shredded sharp cheddar cheese
1 cup shredded mozzarella cheese
½ cup freshly grated Parmesan cheese

For Garnish:

2 tablespoons fresh parsley, chopped
2 tablespoons sliced green onions
Extra Parmesan, optional
Sour cream, optional

Instructions

Wash and scrub the potatoes thoroughly. Dry them well. You can leave the skins on for a rustic texture.
Place each potato between two wooden spoons, chopsticks, or similar guides. Make thin slices about ⅛ inch apart across the potato, cutting down almost to the bottom but not completely through. The guides help prevent accidentally cutting the potato in half.
In a small bowl, combine the melted butter, olive oil, minced garlic, Italian seasoning, paprika, salt, and black pepper.
Brush the garlic-butter mixture generously over each potato. Gently spread the slices slightly so some of the butter mixture gets between the layers.
Lightly grease the slow cooker. Arrange the potatoes cut-side up in the bottom. Try not to pack them too tightly.
Brush the potatoes again with any remaining garlic-butter mixture.
Cover and cook on HIGH for 3½–4 hours or LOW for 6–7 hours, until the centers are completely fork-tender. Slow-cooker potato recipes commonly use similar HIGH/LOW cooking ranges for whole or cut potatoes.
About 15 minutes before serving, carefully sprinkle the cheddar, mozzarella, and Parmesan over the potatoes, working some cheese into the opened slices if possible.
Cover again and cook for 10–15 minutes, or until the cheese is completely melted and gooey. A slow-cooker Hasselback variation also uses Parmesan and mozzarella near the end of cooking to create the cheesy finish.
Remove the lid and let the potatoes rest for about 5 minutes.
Garnish with fresh parsley and green onions. Add extra Parmesan and a spoonful of sour cream if desired.
Serve hot as a side dish with grilled chicken, steak, roast beef, pork, or roasted vegetables.

Tips for the Best Hasselback Potatoes

Choose potatoes that are similar in size so they finish cooking at approximately the same time.

Do not slice completely through the potatoes. Keeping the bottom intact is what creates the classic Hasselback appearance.

Freshly grated cheese melts more smoothly than many pre-shredded varieties.

For stronger garlic flavor, place very thin slices of fresh garlic between some of the potato cuts. Garlic Hasselback recipes commonly place garlic slices directly into the potato openings.

For a crispier top, transfer the cooked potatoes to a baking sheet after slow cooking and place them under a hot broiler for 2–4 minutes until the cheese is bubbling and lightly browned. Watch closely so the cheese does not burn.

For extra richness, brush the potatoes with another tablespoon of melted garlic butter immediately before adding the cheese.

For a loaded version, add crispy bacon, sour cream, green onions, and extra cheddar.

Q&A

Can I use baby potatoes?

Yes. Baby Yukon Gold or small red potatoes work very well, although the cooking time may be shorter depending on their size.

Can I use only cheddar cheese?

Yes. Use about 1½–2 cups of sharp cheddar instead of the three-cheese combination.

Can I use Parmesan only?

Yes, but Parmesan does not become as stretchy as mozzarella. A combination of Parmesan and mozzarella gives a creamier, more melted topping.

Can I prepare the potatoes ahead of time?

Yes. You can wash and cut the potatoes several hours ahead. Keep them covered in the refrigerator until ready to cook.

Why are my potatoes still hard?

Potato size, slow-cooker temperature, and how tightly the potatoes are packed can affect cooking time. Continue cooking until a fork slides easily into the thickest part.

Can I make these without cheese?

Yes. Simply increase the garlic-butter mixture slightly and serve them as garlic-butter Hasselback potatoes.

Can I add bacon?

Yes. Sprinkle cooked, crumbled bacon over the cheese during the final 10–15 minutes.

Can I make them spicy?

Yes. Add ¼–½ teaspoon cayenne pepper, red pepper flakes, or finely chopped jalapeño to the garlic-butter mixture.

How do I store leftovers?

Cool the potatoes and refrigerate them in an airtight container for up to 3–4 days. Reheat in an oven or air fryer for the best texture.

Can I freeze them?

They can be frozen, but the potato texture and cheese sauce may change after thawing. For the best result, refrigerate leftovers instead of freezing them.
