Ingredients

For 8 servings of decadent mashed potatoes, you will need

4 pounds Yukon gold potatoes peeled and quartered
3 cups heavy cream
1 cup whole milk
8 fresh sage leaves plus extra for garnish
3 sprigs fresh thyme plus extra for garnish
4 cloves garlic smashed
1 parmesan rind optional but highly recommended for depth of flavor
6 tablespoons salted butter at room temperature
Kosher salt and freshly cracked black pepper to taste
1 cup shredded Gruyere cheese or more for a cheesier texture

Step-by-Step Instructions

Slow Cooker Method

Combine Ingredients
In the slow cooker bowl, combine the potatoes, parmesan rind (if using), heavy cream, milk, sage, thyme, and garlic. Cover the slow cooker and set it to high for 4–5 hours or low for 6–8 hours, until the potatoes are tender and fork-ready

Drain and Mash
Carefully drain the potatoes, reserving all the cream. Remove and discard the thyme sprigs, sage leaves, and parmesan rind. Use a potato ricer for silky smooth potatoes or a masher for a chunkier texture, and return the mashed potatoes to the slow cooker

Add Cream and Butter
Stir in 1 ½ cups of the reserved cream and the butter. Adjust the cream until the potatoes reach your desired consistency

Cheese and Final Touches
Mix in the Gruyere cheese, cover, and let cook for another 15 minutes until the cheese melts into creamy perfection. Keep the slow cooker on warm for up to 4 hours

Serve
Garnish with fresh herbs and a dollop of butter for a beautiful and aromatic presentation

Instant Pot Method

Pressure Cook
Combine potatoes, parmesan rind, heavy cream, milk, garlic, and sage in the Instant Pot. Cook on low pressure for 15 minutes. Release the steam and switch the Instant Pot to warm mode

Drain and Mash
Drain the potatoes, reserving the cream, and discard the herbs and parmesan rind. Mash the potatoes using your preferred method

Incorporate Cream, Butter, and Cheese
Return mashed potatoes to the Instant Pot. Stir in 1 ½ cups of reserved cream, butter, and Gruyere cheese until melted

Serve
Garnish and enjoy! The potatoes can remain on warm for up to 4 hours

Stove-Top Method

Cook Potatoes
In a large Dutch oven, combine potatoes, parmesan rind, heavy cream, milk, garlic, and sage. Bring to a gentle boil over medium heat and cook for 20–25 minutes, or until fork tender

Drain and Mash
Reserve the cream, discard the herbs and parmesan rind, and mash the potatoes

Finish and Serve
Over low heat, stir in 1 ½ cups of reserved cream, butter, and Gruyere cheese. Serve hot with a garnish of fresh herbs

Vivid Flavors and Textures

Imagine the richness of Gruyere cheese melting seamlessly into velvety Yukon gold potatoes, complemented by the creamy, herby aroma of sage and thyme. Each bite is a harmonious blend of earthy herbs, garlicky warmth, and buttery decadence. The parmesan rind infuses a subtle nuttiness, creating a flavor profile that feels both sophisticated and deeply comforting

Tips for Success

Ingredient Substitutions
Swap Gruyere with sharp cheddar, fontina, or mozzarella for a different cheesy twist
Use half-and-half instead of heavy cream and milk for a lighter version
Add roasted garlic instead of fresh for a sweeter, caramelized note

Variations
Incorporate crispy bacon bits or caramelized onions for added texture
Sprinkle fresh chives or parsley on top for a pop of color and brightness

Serving Suggestions
Serve alongside roasted meats, poultry, or a hearty vegetable stew
Pair with a fresh green salad or roasted vegetables for a balanced meal
