Aligot: French Melted-Cheese Mashed Potatoes

Pommes Aligot ✨ — one of my absolute favorites. Traditionally this dish is made with tome fraîche, which can be hard to find in some areas. I often use Gruyère, and Comté works very well too. The result is the creamiest, most elastic mashed potatoes you’ll ever taste: smooth, cheesy, and comfortingly luxurious.

Why You’ll Love Pommes Aligot

Pommes Aligot is beloved for its rich, stretchy texture and intense cheesy flavor. It’s an ideal side for holiday meals, roast meats, or any time you want to elevate simple potatoes into something special. The technique brings out the starch in the potatoes so the cheese binds smoothly, creating that signature pull and glossy finish. It’s indulgent without being complicated, which makes it a favorite for both home cooks and dinner guests.

How To Prepare Pommes Aligot

1. Peel and cube the potatoes, then place them in a large pot and cover with cold water. Add salt so the water tastes slightly oceany — this seasons the potatoes from the inside out.

2. Bring to a boil and cook the potatoes until they are fork-tender; they should break apart easily when pierced.

3. Drain the potatoes, reserving about 1/4 cup of the starchy cooking liquid. Return the empty pot to low heat, add the cream and a crushed garlic clove, and warm gently to infuse the cream for about 10 minutes. Remove the garlic before proceeding.

4. Push the cooked potatoes through a tamis or fine ricer directly into the warm cream. This creates an ultra-smooth base and releases starch to help with the final texture.

5. Stir in the butter and whip the mixture over low to medium-low heat. The goal is to evaporate any excess moisture and make the potatoes a bit starchy so they can meld with the cheese. Add a pinch of freshly grated nutmeg to taste.

6. Gradually add the grated cheese in small handfuls, stirring vigorously after each addition until the cheese melts and becomes fully incorporated. If the mixture seems too thick, add a splash of the reserved potato water to loosen and encourage a glossy, elastic texture.

7. Continue mixing until the potatoes are glossy and stretch when lifted with a spoon. Taste and adjust seasoning with salt and pepper. Serve immediately for best stretch and texture.

Substitutions and Variations

1. Cheese: If you can find tome fraîche, use it for the most authentic aligot. Otherwise Gruyère or Comté are excellent substitutes. Use a high-quality, evenly grated cheese for smooth melting.
2. Herbs and finishing: A sprinkle of chopped chives or a few snips of parsley adds freshness. You can also finish with a small pat of butter for extra gloss.
3. Milk alternatives: Heavy cream gives the richest result, but if you prefer a lighter version, reduce the amount slightly or use a mixture of cream and whole milk. The texture will be less luxurious but still tasty.
