What Ingredients You Will Need

This recipe calls for simple, wholesome ingredients that work together to create that silky, flavorful garlic confit mashed potatoes experience. Here’s what you’ll need:

• Russet potatoes (about 3 pounds / 1.4 kg, peeled and cubed) – These starchy potatoes yield fluffy, creamy mash. Yukon Golds are a good swap if you want a buttery texture.
• Garlic cloves (1 whole head, peeled) – For confit, softening garlic to sweet perfection.
• Extra virgin olive oil (1/2 cup / 120 ml) – Use a good-quality brand like California Olive Ranch or Colavita for best flavor.
• Unsalted butter (4 tablespoons / 55 grams, softened) – Adds richness and smoothness.
• Heavy cream (1/2 cup / 120 ml, warmed) – For that luscious, creamy texture. You can use half-and-half or whole milk for a lighter option.
• Salt (to taste) – I recommend kosher salt for better seasoning control.
• Freshly ground black pepper (to taste) – Just a pinch to balance the flavors.
• Fresh chives or parsley (optional, finely chopped for garnish) – Adds a pop of color and freshness.

If you prefer dairy-free, swap butter and cream with coconut oil and almond milk, but the flavor will shift slightly. For garlic, try to find firm, plump cloves; this helps the confit process work better and keeps the flavor mellow. If fresh garlic isn’t available, you can use pre-peeled cloves, but fresh is always best.

Equipment Needed

• Medium saucepan – For simmering the garlic confit gently in olive oil. A heavy-bottomed pot helps prevent burning.
• Large pot – To boil the potatoes evenly.
• Potato masher or ricer – I prefer a ricer for the silkiest texture, but a sturdy masher works just fine.
• Mixing bowl – To combine and finish the mashed potatoes.
• Wooden spoon or silicone spatula – For folding in butter, cream, and garlic confit.
• Colander – To drain the potatoes thoroughly.

If you don’t have a ricer, no worries—using a masher and then passing through a fine sieve works well too. A thermometer isn’t necessary, but I often check that the cream is warmed to avoid cooling the mash. For budget-friendly options, any sturdy saucepan and masher will do the trick.

Detailed Preparation Method

1. Prepare the garlic confit: Place the peeled garlic cloves and olive oil in a medium saucepan. Heat over low heat—keep it below a gentle simmer, around 200°F (93°C). Cook for 30-40 minutes, stirring occasionally, until the garlic is soft, golden, and fragrant. Be patient here; rushing with higher heat will burn the garlic and ruin the flavor.
2. Boil the potatoes: While the garlic cooks, add peeled and cubed potatoes to a large pot of cold salted water (about 1 tablespoon salt per 4 cups water). Bring to a boil over high heat, then reduce to medium, cooking until tender—about 15-20 minutes. Test by piercing with a fork; they should break apart easily.
3. Drain the potatoes: Once cooked, drain them thoroughly in a colander. Let them sit for a minute to steam off excess moisture—this helps keep your mash fluffy.
4. Mash the potatoes: Return the potatoes to the pot or a large bowl. Use a potato ricer if you have one, or a masher to break them down until smooth but not gluey.
5. Add butter and cream: Stir in softened butter and warmed heavy cream gradually. Mix gently to combine—don’t overwork the potatoes or they’ll turn gummy.
6. Incorporate garlic confit: Using a spoon, mash the garlic cloves from the confit directly into the potatoes. Pour in some of the garlic-infused olive oil too for extra flavor and silkiness. Taste and season with salt and black pepper.
7. Final touches: Fold in chopped fresh chives or parsley if using. Cover to keep warm while you finish other dishes.

If the mash feels too thick, add a splash more warm cream or reserved cooking water. If it’s too loose, a quick extra mash or a bit more butter can help. The garlic confit oil is golden and fragrant, so don’t skimp on adding it—you’ll notice the difference immediately. This step is where the magic happens!

Cooking Tips & Techniques

One little trick I learned early on is to keep the garlic confit at a very low temperature. You want it simmering gently, not frying—this slow process brings out the sweetness and eliminates harshness. I’ve burned garlic more times than I care to admit, and trust me, it’s not worth the risk.

When mashing, less is more. Overworking potatoes can release starches that make your mash gluey and dense. Using a ricer or food mill gives the fluffiest results, but if you only have a masher, just be gentle and patient.

Always warm your cream or milk before adding it in. Cold liquid can shock the potatoes and make them tough or lumpy. A quick zap in the microwave or gentle warming on the stove does the trick.

Finally, taste as you go! Garlic confit varies in intensity depending on how long you cook it and the garlic itself. Start with a little, then add more to avoid overpowering the delicate balance.

Variations & Adaptations

• Herb-infused version: Add fresh rosemary or thyme sprigs to the garlic confit oil as it simmers for an earthy twist.
• Cheesy confit mash: Stir in grated Parmesan or Gruyère just before serving for a rich, savory upgrade.
• Vegan adaptation: Swap butter for vegan butter or olive oil, and use unsweetened plant-based milk instead of cream. The garlic confit oil will keep it flavorful.
• Spicy garlic mash: Toss in a pinch of red pepper flakes to the confit or sprinkle on top for a subtle heat kick.

I once tried folding in caramelized onions with the garlic confit for a dinner party—it was a hit! Feel free to experiment with your favorite flavors or seasonal ingredients like roasted sweet potatoes or parsnips.

Serving & Storage Suggestions

This garlic confit mashed potatoes recipe is best served warm, straight from the pot, with a drizzle of the garlic oil on top and a sprinkle of fresh herbs for color. It pairs beautifully with roasted turkey, glazed ham, or even a hearty mushroom gravy.

Leftovers store well in an airtight container in the fridge for up to 3 days. Reheat gently on the stove or in the microwave, adding a splash of cream or milk to loosen the texture. You can also freeze mashed potatoes, but they’re best thawed slowly in the fridge and reheated carefully to maintain creaminess.

Fun fact: the flavors deepen overnight, so if you can make this a day ahead, go for it! Just warm it up slowly and stir in a little extra butter or cream before serving.
