This Harvest Potato Mash is what happens when a classic russet potato and a sweet potato 🥔🍠 stop fighting over which one is better and just decide to become better, together 🥹. The result is a buttery, fluffy, golden bowl of pure comfort 😍 that is equal parts savory and sweet. The russet brings the familiar, cozy fluffiness, the sweet potato shows up with a hint of natural sweetness and the prettiest orange 🧡 hue. Neither of them could have done this without the other. Teamwork makes the dream work, bestie 👯.
Harvest Potato Mash
A cozy, swirled mash of russet and sweet potatoes that’s buttery, fluffy, and the perfect balance of savory and sweet.
Ingredients
- 1 large russet potato, peeled and chopped
- 1 medium sweet potato, peeled and chopped
- ⅓ cup milk, dairy or unsweetened alternative
- 1 tablespoon butter
- ½ teaspoon salt, or to taste
- Optional: black pepper or garlic powder, to taste
Instructions
- Add the peeled and chopped russet potatoes and sweet potatoes to a medium pot with enough cold water to cover, along with a generous pinch of salt.
- Bring to a boil, then reduce to a simmer and cook for 15 to 20 minutes, or until the potatoes are fork tender.
- Drain the potatoes well and return them to the warm pot. Let them sit for about a minute so the extra steam escapes. This small step keeps the mash fluffy instead of watery.
- Using a potato masher, mash the potatoes just enough to break them down. Don’t overmix—you want the russet and sweet potato to stay a little separate so you get those beautiful golden swirls.
- Pour in the milk, add the butter and salt, and mash gently again until everything comes together.
- Taste and adjust the seasoning if needed. Add black pepper or a pinch of garlic powder if using. Serve warm and enjoy!
Nonna's Tip: warm the milk before adding to help the mash stay smooth and creamy without needing extra butter or cream.
Nonna’s Notes
Texture Tip: For that beautiful marbled look, mash the potatoes gently and stop before they become completely smooth. The contrast between the russet and sweet potato is what makes this recipe special.
- Variations: Swap the russet for Yukon Gold potatoes if you prefer an extra creamy mash. You can also stir in roasted garlic, fresh herbs like thyme, or a sprinkle of parmesan for extra flavor.
- Dairy-Free: Use your favorite unsweetened plant-based milk and dairy-free butter.
- Storage: Store leftovers in an airtight container in the fridge for up to 3–4 days.
- Reheating: Reheat gently in the microwave or in a small saucepan over low heat with a splash of milk to prevent dryness.
- Freezer Friendly: You can freeze the mash in a sealed container for up to 2 months. Thaw overnight in the fridge and reheat slowly with a little milk to restore the creamy texture.
