In my opinion, French onion dip is one of the greatest dips of all time. When you take one of those unassuming seasoning packets and mix it with sour cream, it becomes so much greater than the sum of its parts. So, I applied that same idea to mashed potatoes! Meet: French onion mashed potatoes.
Ingredients You’ll Need
- Yukon Gold potatoes: For buttery and creamier mashed potatoes, start with Yukon Gold potatoes. They’re less starchy than russets, yielding a more concentrated flavor and creamier texture.
- Onion soup mix: The dehydrated onions will soften when mixed with the potatoes, but the flavor still packs a punch.
- Sour cream: Its creamy tang ties everything together.
Make This Dish Your Own
French onion dip mashed potatoes are delicious on their own, but you can add toppings to make them even more special. Try it with a few pats of butter, thinly sliced chives, or even a handful of crushed potato chips for an extra touch.French Onion Mashed Potatoes
Makes about 7 cups; serves 6 to 8- 3 pounds Yukon Gold potatoes
- 1 tablespoon kosher salt, plus more as needed
- 8 ounces full-fat sour cream (1 cup)
- 1 (1-ounce) envelope onion soup mix, such as Lipton’s
- Freshly ground black pepper
- 4 tablespoons (1/2 stick) unsalted butter (optional)
- 3 tablespoons finely chopped chives (optional)
2. When the potatoes are ready, reserve 1 cup of the cooking liquid. Drain the potatoes. Return 1/2 cup of the cooking liquid to the now-empty pot and add 8 ounces sour cream and 1 packet onion soup mix. Stir until smooth.
3. Pass the potatoes through a ricer into the pot, or return the potatoes to the pot and mash with a potato masher until desired consistency. Gently stir to combine. If the mashed potatoes are too thick, add more of the reserved cooking liquid as needed to loosen. Taste and season with more kosher salt and black pepper as needed.
4. Transfer to a serving bowl. Cut 4 tablespoons unsalted butter into pats and scatter over the mashed potatoes if desired. Garnish with chives if desired.
- Make ahead: The potatoes can be peeled and placed in the pot with the water and kosher salt and kept at room temperature for up to 4 hours before cooking.
- Storage: Leftover mashed potatoes can be refrigerated in an airtight container for up to four days.
