When the foil packet comes out of the oven, the garlic cloves should give way with almost no pressure. If they’re still firm, they’ll taste sharper than the mellow, sweet cloves that make this mash work. Roasted garlic mashed potatoes need no dairy to feel rich: Yukon Golds, vegan butter, and unsweetened plant milk build a creamy base around that soft garlic.
I roast the garlic while the potatoes simmer, then warm the butter and plant milk together before they go into the pot. That small bit of timing matters: warm liquid blends into hot potatoes more smoothly than cold liquid, and adding it gradually lets you stop when the mash is creamy rather than loose. Each bite has a gentle garlic flavor and a soft, buttery finish.
Kitchen Note
Starting the potatoes in cold water gives the chunks time to heat evenly from the outside in. Keep the water about an inch above them, so the top pieces don’t sit exposed while the pot comes to a boil.
Save these vegan roasted garlic mashed potatoes for a creamy, dairy-free side with mellow roasted garlic in every serving.
Warm Plant Milk Is What Keeps These Potatoes Creamy, Not Heavy
Hot potatoes take in warm liquid more readily than cold liquid. When cold plant milk hits the pot, it cools the potatoes while the vegan butter firms up; the mash can feel uneven before you’ve had a chance to blend everything together. Warming the two together gives you a smooth, ready-to-mix addition without bringing the milk to a boil.
Adding that mixture gradually matters just as much. Potato varieties and even the size of the cooked chunks can affect how much liquid the mash seems to need, so pour in a little at a time and pause to check the texture. Stop when the potatoes look creamy and hold softly on the spoon. If you pour everything in at once, it’s harder to correct a mash that has gone loose.
Why Yukon Golds and Roasted Garlic Belong in the Same Pot
- Yukon Gold potatoes — Their naturally creamy texture suits a mash that gets richness from vegan butter and plant milk. Cut the chunks to a similar size so they soften at about the same pace. If you need a substitute, russets work at the same potato weight but give you a fluffier, less buttery-tasting mash.
- Whole garlic — Roasting turns the cloves soft enough to mash into the potatoes and rounds off garlic’s sharper edge. Choose a firm head with tight cloves; there isn’t a direct shortcut that gives raw or jarred garlic the same mellow roasted character.
- Vegan butter — This brings the fat and buttery richness that make the potatoes feel full-bodied. A familiar brand you already enjoy is fine; replacing it with straight oil won’t give the mash the same rounded texture.
- Unsweetened plant milk — Plain, unsweetened milk keeps the mash savory and supplies the moisture that helps the potatoes turn creamy. Any neutral-tasting unsweetened plant milk works; oat, soy, or almond milk can stand in for one another here. Skip vanilla or sweetened versions, which can make the potatoes taste noticeably sweet.
- Olive oil — A drizzle coats the exposed garlic before roasting and helps the cloves soften inside their foil packet. There’s no need to use an expensive bottle for this; a straightforward olive oil is enough.
Roast the Garlic, Simmer the Potatoes, Then Mash While Warm
Roast Until the Cloves Are Soft and Golden
Heat the oven to 400°F. Slice about 1/4 inch from the top of the garlic head to expose the cloves, set it on foil, drizzle with olive oil, and wrap the packet tightly. Roast it on a small baking sheet for 40 to 50 minutes, until the cloves are very soft and golden. Let the packet cool until it’s safe to handle before squeezing the cloves from their skins.
Simmer the Yukon Gold Chunks Until Fork-Tender
Put the scrubbed potatoes, cut into 1 1/2-inch chunks, in a 4-quart pot and cover them with cold water by 1 inch. Add 1 1/2 teaspoons of the kosher salt, bring the pot to a boil over high heat, then reduce the heat and simmer for 15 to 20 minutes. Check a larger chunk with a fork; it should slide in without a firm center. If the middle still resists, keep simmering until the chunks are tender.
Warm the Butter and Plant Milk Gently
While the potatoes cook, combine the vegan butter and plant milk in a small saucepan over low heat. Warm the mixture until the butter melts and the liquid is hot, but don’t let it boil. A gentle heat keeps the mixture ready to blend into the potatoes without scorching it. If you see it bubbling, take the pan off the burner.
Mash Gradually for a Creamy Finish
Drain the potatoes thoroughly and return them to the pot. Mash them with the roasted garlic, then gradually mix in the warm butter and milk along with the remaining kosher salt and black pepper. Pause as you mix to check the texture rather than adding the liquid all at once. Stop when the potatoes are creamy and the garlic is distributed through the mash.
Two Texture Changes That Keep the Same Garlic-Butter Balance
Leave a Few Soft Potato Pieces
For a more rustic bowl, mash the potatoes and roasted garlic only until the large chunks are gone, then mix in the warm butter and milk gradually. The finished potatoes will have a little more texture than a fully smooth mash, while keeping the same mellow garlic flavor.
Use a Ricer for a Finer Mash
Press the cooked potatoes through a potato ricer instead of mashing them by hand, then work in the roasted garlic and warm butter-milk mixture. This gives you a more uniform, delicate texture. Add the liquid gradually so the finer mash doesn’t become loose.
Storage and Reheating
- Refrigerator: Transfer the potatoes to a covered, shallow container and refrigerate within 2 hours. They keep for 3 to 4 days; chilling firms the mash, so it won’t be as soft as when freshly made.
- Freezer: The mash freezes, though it may be a little grainy after thawing. Portion it into an airtight freezer-safe container, freeze for up to 1 month for the best texture, and thaw overnight in the refrigerator.
- Reheating: Warm the potatoes gently in a saucepan over low heat, stirring often. If they’ve thickened, stir in a little unsweetened plant milk and heat to 165°F. High heat can scorch the bottom before the center is hot.
