Slow Cooker Garlic Parmesan Potatoes

by

Recipe Description

These potatoes are sliced into thick rounds to maintain a pleasant bite while soaking up a decadent sauce made of heavy cream, aromatic garlic, and sharp Parmesan cheese. Slow cooking allows the starch from the potatoes to naturally thicken the sauce, resulting in a velvety texture that is far superior to oven-roasting when you want something truly indulgent.

  • Prep time: 15 minutes

  • Cook time: 4 hours (High) or 7-8 hours (Low)

  • Servings: 6 servings

Ingredients

  • Potatoes: 3 lbs Yukon Gold or Red potatoes (sliced into 1/2 inch rounds)

  • Cream Base: 1 cup heavy cream & 1/2 cup chicken or vegetable broth

  • Aromatics: 4 cloves garlic (minced) & 1 small yellow onion (finely diced)

  • Cheese: 1 cup freshly grated Parmesan cheese

  • Seasoning: 1 tsp dried thyme, 1 tsp paprika, salt, and black pepper to taste

  • Garnish: Fresh chopped parsley

Step-by-Step Instructions

  1. Prep the Slow Cooker: Grease the inside of your slow cooker with butter or non-stick spray.

  2. Layer: Place the sliced potatoes and onions into the slow cooker.

  3. Whisk Sauce: In a medium bowl, whisk together the heavy cream, broth, minced garlic, thyme, paprika, salt, and pepper.

  4. Combine: Pour the mixture over the potatoes. Toss gently to ensure every slice is coated.

  5. Cook: Cover and cook on High for 4 hours or Low for 7-8 hours until the potatoes are fork-tender.

  6. The Finish: About 20 minutes before serving, stir in the Parmesan cheese. Cover and let it melt into a creamy glaze. Top with fresh parsley before serving.

Expert Tips & Notes

  • Potato Choice: Use Yukon Golds for the creamiest texture; they hold their shape better than Russets, which tend to fall apart in a slow cooker.

  • Even Slicing: Try to keep your slices uniform (about 1/2 inch) so they all finish cooking at the same time.

  • Curdling Prevention: If you notice the sauce looks slightly grainy, it’s usually because the cheese was added too early or wasn’t freshly grated. Use a block of Parmesan rather than the “shaker” kind for a smoother melt.

Q&A

Q: Can I make this dairy-free? A: Yes, you can substitute the heavy cream with full-fat coconut milk or a plant-based heavy cream alternative, and use nutritional yeast or a vegan Parmesan substitute.

Q: Why are my potatoes still hard after 4 hours? A: Slow cookers vary in temperature. If they are still firm, it’s likely the lid was lifted too often (which releases heat) or the slices were cut too thick. Give them another 30-60 minutes.

Q: Do I need to peel the potatoes? A: For Yukon Gold or Red potatoes, the skin is thin and nutritious, so peeling is optional! It adds a nice rustic look and extra fiber.
