Rich, creamy and slightly tangy, these Mashed White Sweet Potatoes elevate your usual comfort food. They work wonderfully as a Thanksgiving side or alongside any holiday roast or hearty main.
I adore classic mashed potatoes—my Buttermilk Mashed Potatoes and Rosemary Garlic Mashed Potatoes are staples—so I wanted to try a different variety this time. Japanese sweet potatoes (sometimes called Murasaki) with white flesh and a reddish skin are perfect for roasting, baking, or, in this case, mashing.
After testing white-fleshed sweet potatoes in this mashed version, I’m hooked—this is now a favorite side dish for holidays and weeknight dinners alike.

Why You’ll Love This Recipe
If you enjoy regular mashed potatoes, this version with white sweet potatoes offers a fresh twist:
- Show-stopping side: Creamy, tangy, and balanced between sweet and savory—perfect for holiday tables.
- Fast and easy: Minimal hands-on time; most of the work is boiling or roasting.
- Simple ingredients: Pantry staples plus white-fleshed Japanese sweet potatoes are all you need.
Pro Tips
Small adjustments make a big difference—use these tips for the creamiest, smoothest mash:
- For ultra-smooth texture, press potatoes through a fine mesh sieve or use a potato ricer instead of overworking with a mixer.
- Mash while hot to avoid lumps and make blending easier.
- Use high-quality butter (European-style if possible) for richer flavor.
- Let cream cheese come to room temperature before adding so it blends evenly.
- For extra flavor, drizzle with garlic butter or top with grated Parmesan.
Ingredients
Simple ingredients yield rich results:
- Japanese sweet potatoes: White-fleshed, often called Murasaki; available at many markets.
- Butter: Unsalted for control over seasoning.
- Milk: Whole milk or half-and-half for creaminess; warm before adding.
- Cream cheese: Adds tang and richness.
- Salt & pepper: Keep seasoning simple and adjust to taste.
- Chives: Fresh, chopped for garnish (or green onions).
Refer to the recipe card for exact measurements.
Tip: For deeper flavor, roast the potatoes at 400°F (200°C) for 45–60 minutes until fork-tender, then mash.
Substitutions & Variations
- Mixed sweet potatoes: Combine orange and white sweet potatoes for color and sweetness.
- Lighten it: Use low-fat cream cheese or Greek yogurt instead of full-fat cream cheese.
- More savory: Stir in grated Parmesan or roasted garlic.
- Extra creaminess: Add a splash of heavy cream.
- Warm spices: Add cinnamon or nutmeg for a cozy note.
How to Make Mashed White Sweet Potatoes
This mashed sweet potato recipe is straightforward. Follow these steps for reliable results:
Step 1: Peel and Chop
Peel and rinse the potatoes, pat dry, and cut into roughly 1-inch chunks.
Step 2: Boil
Place the chunks in a pot, cover with cold water, bring to a boil, then reduce to a simmer. Cook about 15–20 minutes until fork-tender.
Step 3: Drain & Mash
Drain well and mash while still hot. For the smoothest texture, use a fine-mesh sieve or potato ricer; a masher works too.
Step 4: Add Butter, Milk and Cheese
Stir in butter, warm milk, and cream cheese until fully combined and creamy.
Step 5: Season & Finish
Taste and season with salt and pepper. Top with chopped chives and serve immediately.
Don’t use a food processor to mash—this can make potatoes gummy. If using a mixer, whip briefly and gently to avoid a gluey texture.
How to Serve
- These mashed white sweet potatoes pair beautifully with roasted meats like duck, turkey, or chicken and also with steaks or lamb chops.
- Complement them with simple vegetable sides such as buttered green beans or bacon-scented greens.
Make Ahead, Storage, and Reheating
- Make ahead: Freeze in freezer-safe containers for up to 6 months.
- Storage: Refrigerate leftovers in an airtight container for up to 2 days.
- Reheating: Reheat on the stovetop over medium heat with a splash of milk to restore creaminess, or warm in the oven covered with foil. If using a microwave, heat in short intervals and stir between each.
Common Questions
Yes. Substitute plant-based butter and a non-dairy milk, and use vegan cream cheese for richness. Coconut or almond milk both work well.
Salt and pepper keep it classic, but cumin, garlic powder, onion powder, paprika, or dried herbs all complement the potatoes nicely.
