Step 5: Add the Cheese

Once the potatoes are tender, carefully open the slices slightly if they haven’t separated naturally.

Sprinkle Parmesan and cheddar or Gruyère over the potatoes, allowing some cheese to fall between the slices.

Drizzle with the remaining garlic butter mixture.

Cover the crockpot again and cook for another 10–15 minutes, or until the cheese has melted.

At this stage, the potatoes will be wonderfully tender and cheesy.

Step 6: Give Them a Crisp Finish

The potatoes are delicious directly from the slow cooker, but if you want the classic Hasselback appearance with golden, crisp edges, there is one extra step.

Carefully transfer the cooked potatoes to a baking sheet lined with parchment paper or foil.

Brush them lightly with any remaining butter.

Place them under a preheated broiler for a few minutes until the tops become golden and the edges begin to crisp.

Watch them closely because they can brown quickly.

This finishing step isn’t necessary, but it gives the potatoes a much more traditional Hasselback texture.

Step 7: Garnish and Serve

Transfer the finished potatoes to a serving platter.

Sprinkle them with freshly chopped parsley and green onions.

For an extra-loaded version, add a little more Parmesan, crispy bacon, or chopped chives.

Serve immediately while the cheese is warm and melted.

Helpful Tips for Perfect Hasselback Potatoes

Don’t cut all the way through

This is the most important part of the recipe. The slices should remain connected at the bottom. Using chopsticks or spoon handles as cutting guides makes this much easier.

Don’t overcrowd the crockpot

Arrange the potatoes in as close to a single layer as possible. If they are tightly packed, they may cook less evenly.

Use enough seasoning

Potatoes are naturally mild, so don’t be afraid to season them generously. Garlic, butter, herbs, cheese, and smoked paprika work especially well together.

Check for tenderness

Slow cookers vary considerably. Start checking the potatoes toward the earlier end of the recommended cooking time.

Broil for texture

Slow cooking creates wonderfully tender potatoes, but it doesn’t provide the same crisp surface as an oven. A quick broil at the end solves that problem.

Delicious Variations

Bacon and Cheddar Hasselback Potatoes

Add cooked, crumbled bacon between the potato slices before adding the cheddar. Finish with green onions and sour cream.

Garlic Herb Potatoes

Skip the stronger cheeses and use Parmesan with fresh rosemary, thyme, parsley, and extra garlic.

Loaded Hasselback Potatoes

Top the finished potatoes with cheddar, bacon, sour cream, and green onions for a loaded-baked-potato version.

Spicy Hasselback Potatoes

Add a pinch of cayenne pepper or red pepper flakes to the butter mixture. Pepper Jack cheese can replace the cheddar for extra heat.

Parmesan Rosemary Potatoes

Use freshly grated Parmesan, chopped rosemary, garlic, and black pepper for a simple but elegant variation.

What to Serve With Crockpot Hasselback Potatoes

These potatoes pair well with almost any hearty main course. Serve them alongside:

• Roast chicken
• Grilled steak
• Pork chops
• Roast beef
• Baked salmon
• Grilled vegetables
• Meatloaf
• Holiday turkey
• Glazed ham

They’re also substantial enough to become part of a casual buffet or family-style dinner.

How to Store Leftovers

Allow leftover potatoes to cool before transferring them to an airtight container. Refrigerate for up to 3–4 days.

To reheat, place them in an oven or air fryer until heated through. The oven or air fryer will help restore some of the crispness that is lost during refrigeration.

Microwaving works when you’re short on time, although the potato edges will remain softer.

Final Thoughts

Crockpot Hasselback Potatoes are a great example of how a simple ingredient can become a memorable side dish with a little preparation. The thin slices create plenty of places for garlic butter, herbs, and melted cheese to settle, while slow cooking gives the potatoes a soft, creamy interior.

For the best results, focus on making careful slices without cutting completely through the potatoes, season them generously, and finish them under the broiler if you want beautifully browned and crispy edges.

Whether you’re preparing a weeknight dinner or putting together a holiday meal, these potatoes offer an easy combination of tender centers, buttery garlic flavor, melted cheese, and crispy edges that makes them hard to resist.
