Creamy and Cheesy Garlic Herb Mashed Potatoes

Nothing says comfort like a bowl of creamy, cheesy mashed potatoes, and these Slow Cooker Cheesy Garlic Herb Mashed Potatoes are loaded with flavor. Made with Gruyere, fresh herbs, and garlic, they’re the ultimate side dish for any cozy meal or holiday gathering.

Ingredients

• Yukon Gold Potatoes: These potatoes have a naturally creamy texture, making them ideal for mashed potatoes.
• Heavy Cream: Adds richness and helps create the smooth, creamy consistency that makes these mashed potatoes indulgent.
• Whole Milk: Balances the heavy cream, adding creaminess without making the dish too rich.
• Fresh Sage Leaves: Brings an earthy flavor that pairs beautifully with the creamy potatoes and cheese.
• Fresh Thyme Sprigs: Adds subtle herbal notes, enhancing the overall flavor profile.
• Garlic (smashed): Infuses the potatoes with a mild garlic flavor, making them extra savory.
• Parmesan Rind (optional): Adds an extra layer of umami, making the potatoes even more flavorful.
• Salted Butter (at room temperature): Adds richness and helps create a smooth, velvety texture.
• Kosher Salt and Black Pepper: Essential seasonings to enhance the flavor of the mashed potatoes.
• Gruyere Cheese (shredded): A nutty, flavorful cheese that melts beautifully, adding creaminess and depth.

Instructions

Slow Cooker Method:

In your slow cooker, combine the potatoes, parmesan rind (if using), heavy cream, milk, sage, thyme, and garlic. Cover and cook on high for 4-5 hours or on low for 6-8 hours, until the potatoes are fork-tender. Switch the slow cooker to warm.

Step 2:

Drain the potatoes, reserving all of the cream. Discard the thyme, sage, and parmesan rind (if used). Press the potatoes through a potato ricer, adding them back to the slow cooker. Alternatively, you can add the potatoes back to the slow cooker and mash with a potato masher.

Step 3:

Add 1 1/2 cups of the reserved cream and the butter to the potatoes. Gradually add more of the cream until you reach your desired consistency. Season with salt and pepper, then stir in the shredded Gruyere. Cover and cook for an additional 15 minutes until the cheese is melted and creamy. Keep the potatoes covered on warm for up to 4 hours.

Instant Pot Method:

In your Instant Pot, combine the potatoes, parmesan rind (if using), heavy cream, milk, garlic, and sage. Cover and cook on low pressure for 15 minutes, then release the steam. Switch the Instant Pot to warm, and proceed as with the slow cooker instructions, adding the butter, reserved cream, and cheese until the potatoes are creamy.

Stove-Top Method:

In a large Dutch oven, combine the potatoes, parmesan rind (if using), heavy cream, milk, garlic, and sage. Bring to a gentle boil over medium heat and cook for 20-25 minutes, until the potatoes are fork-tender. Drain the potatoes, reserving the cream, then mash and finish as with the other methods.

Serving and Storage Tips

• Serve hot, topped with additional fresh sage, thyme, and a bit of extra butter for garnish.
• This dish pairs wonderfully with roasted meats, grilled vegetables, or a holiday spread.
• Store leftovers in an airtight container in the refrigerator for up to 3 days.
• To reheat, warm gently on the stove or in the microwave, stirring occasionally. Add a splash of milk or cream to restore the creamy texture if needed.

Helpful Notes

• If you prefer a stronger garlic flavor, consider adding an extra clove or two to the slow cooker.
• For an even cheesier flavor, add extra Gruyere or substitute with sharp cheddar.
• Adjust the consistency to your liking by adding more or less of the reserved cream.
