Garlic-Thyme Mascarpone Mashed Potatoes
Mashed potatoes are always good, but a few simple changes can make them even better. In this recipe, I use mascarpone cheese instead of heavy cream for a rich, velvety texture that pairs beautifully with fresh thyme and garlic.
What makes these mashed potatoes different is how they’re cooked. Instead of boiling the potatoes in plain water, I simmer them in a combination of milk and water with smashed garlic and fresh thyme.
As the potatoes cook, they absorb some of those flavors, creating a delicious foundation before the mascarpone is even added.
I also reserve some of the starchy cooking liquid to adjust the consistency as I mash. The result is creamy, flavorful mashed potatoes without needing to add heavy cream.
Why I Use Mascarpone
Mascarpone is a rich, mild Italian cheese that gives mashed potatoes a wonderfully smooth, velvety consistency. I prefer it over heavy cream or sour cream for a few reasons:
Rich, creamy texture: Mascarpone blends into the warm potatoes, adding richness and a smooth consistency without requiring much additional liquid.
Mild flavor: Unlike cream cheese or sour cream, mascarpone doesn’t have a pronounced tanginess. Its delicate, slightly sweet flavor allows the garlic and fresh thyme to stand out.
Easy to incorporate: When gently folded into warm mashed potatoes, mascarpone blends smoothly without needing vigorous mixing, which can make potatoes gummy.

Instructions
Rinse the potatoes: Place the peeled and cut potatoes in the saucepan you’ll be using to cook them. Fill with cold water, swish the potatoes around with your hand, and drain. Repeat about three times, or until the water runs mostly clear, to remove excess surface starch.
Cook the potatoes: Add the garlic, thyme sprigs, milk, and enough fresh water to cover the potatoes. Season with salt. Bring to a gentle simmer and cook until fork-tender, approximately 20–25 minutes.
Reserve the cooking liquid: Remove the thyme stems. Before draining the potatoes, reserve about 1 cup of the cooking liquid. Drain the potatoes, keeping the softened garlic.
Dry the potatoes: Return the potatoes and garlic to the warm saucepan over low heat for about 1 minute, allowing excess moisture to evaporate.
Mash: Mash the potatoes and garlic until fluffy. Add the butter, followed by the mascarpone, gently folding everything together.
Adjust the consistency: Add the warm reserved cooking liquid a tablespoon at a time until the potatoes reach your preferred creamy consistency. Finish with freshly ground black pepper and fresh thyme leaves.
Serving Garlic-Thyme Mascarpone Mashed Potatoes
These mashed potatoes make a delicious side dish for roasted meats, poultry, and hearty comfort-food dinners.
Their mild, buttery flavor complements everything from roasted chicken and pork chops to slow-cooked beef.
They’re especially good alongside dishes with pan juices or a savory sauce that can be spooned over the potatoes.
For serving, transfer the mashed potatoes to a warm bowl, create a few soft swirls with the back of a spoon, and sprinkle with a little additional fresh thyme if desired.
Storage and Reheating
Allow leftover mashed potatoes to cool slightly before transferring them to an airtight container. Refrigerate within two hours and store for up to 3–4 days.
To reheat on the stovetop, place the potatoes in a saucepan over low heat. Add a splash of milk and stir gently until heated through.
You can also reheat individual portions in the microwave, stirring between short heating intervals. Add a little milk if needed to restore their creamy consistency.

Frequently Asked Questions
Can I use a different type of potato?
Russets and Yukon Golds are the best choices for this recipe. Russets produce a light, fluffy texture, while Yukon Golds have a naturally buttery flavor and create a creamier mash. I’d avoid waxier potatoes, such as red potatoes, because they tend to produce a denser, stickier consistency.
Roasted Red Potatoes with Garlic Parmesan
If you enjoy cooking with red potatoes, try my Roasted Red Potatoes with Garlic Parmesan for a delicious alternative that makes the most of their naturally firm texture.
What if I don’t have fresh thyme?
You can substitute dried thyme, although fresh thyme gives this recipe a more delicate flavor. Use about ½ teaspoon dried thyme in the cooking liquid, then taste the finished potatoes before adding a small pinch more if needed.
Can I use rosemary instead of thyme?
Yes. Fresh rosemary works well with garlic and mascarpone, although it creates a different flavor. Rosemary has a stronger, more woodsy flavor than thyme, so start with a smaller amount. You can simmer a sprig with the potatoes and remove the stem before mashing.
This particular recipe uses fresh thyme for its more delicate, earthy flavor.
Can I make these mashed potatoes ahead of time?
Yes. Prepare them a few hours ahead, then refrigerate until you’re ready to serve. Reheat gently in a covered saucepan over low heat, adding a splash of warm milk if needed to restore their creamy consistency.
Can I use cream cheese instead of mascarpone?
Yes, but it will change the flavor. Cream cheese has a noticeably tangier taste, while mascarpone is mild, rich, and buttery. Both can make creamy mashed potatoes, but mascarpone allows the garlic and fresh thyme to stand out without adding that tanginess.
Can I freeze mascarpone mashed potatoes?
Yes, although the texture may change slightly after thawing. The butter and mascarpone help maintain richness, but the potatoes may need a little milk when reheated.
Freeze in airtight, freezer-safe containers for up to 2 months for best quality. Thaw overnight in the refrigerator before reheating gently.
