The Best Savory Mashed Sweet Potatoes
Sweet potatoes usually get the marshmallow-and-brown-sugar treatment, but they're just as delicious savory! Here they're mashed with garlic, rosemary, parsley, and onion powder, so you get a cozy herby side that pairs with just about any dinner. Trust me, sweet potatoes work in mashed form just as well as russets or Yukon Golds.
This recipe is also lighter than most mashed sweet potato recipes. Many call for ½ to ¾ cup of butter plus milk. We're using just 4 tablespoons of butter and swapping in Greek yogurt for creaminess, and you'd never know the difference! Looking for an even lighter mash? Try my Mashed Cauliflower Potatoes.
These make the perfect Thanksgiving or Friendsgiving side. Serve them alongside my Sausage Stuffing Muffins with Cranberry Sauce and Cranberry Turkey Meatballs for a holiday spread everyone will love.

Ingredients Needed To Make These Savory Mashed Sweet Potatoes
Here's a little bit about everything that goes into these fluffy, herby sweet potatoes!

- Sweet potatoes: You'll need about 4.5 lbs, peeled and diced into chunks.
- Butter: Just 4 tablespoons for that rich, classic mashed potato flavor.
- Plain Greek yogurt: The secret to a creamy texture without all the extra butter.
- Garlic: Fresh minced garlic is key to the savory flavor.
- Fresh rosemary and parsley: These herbs make the dish taste cozy and holiday-ready.
How to Make Savory Mashed Sweet Potatoes
These come together just like regular mashed potatoes! Simmer the sweet potato chunks until they're fork-tender, then drain them and mash everything together right in the pot.
The key is taking your time with the mashing. A few extra minutes give you that super soft, fluffy texture.

- Step 1: Add the sweet potato chunks to a large saucepan or Dutch oven and cover with 3 inches of water.

- Step 2: Cover and cook over medium-high heat for 25–30 minutes, or until fork-tender. Drain the water and return the potatoes to the pan.

- Step 3: Add the butter, Greek yogurt, garlic, salt, pepper, onion powder, rosemary, and parsley.

- Step 4: Mash with a potato masher for several minutes until very soft and creamy. Season with extra salt and pepper to taste and serve topped with a pat of butter.
Erin's Expert Tips
From my kitchen to yours
- Cut the potatoes small. Smaller chunks cook faster and get fork-tender perfectly.
- Mash until creamy. Don't rush it. A few extra minutes of mashing makes them ultra fluffy.
- Don't skip the Greek yogurt. It adds creaminess without weighing the potatoes down.
- Try the secret ingredient. A few tablespoons of maple syrup mixed in or drizzled on top pairs perfectly with the savory herbs.
- Use fresh herbs. Fresh rosemary and parsley make a big difference in flavor.

Storing leftovers

- 4.5 lbs sweet potatoes peeled and diced into chunks
- 4 tablespoon butter
- ⅓ cup plain greek yogurt
- 3 cloves garlic minced
- 1.5 teaspoon salt
- 1 teaspoon pepper
- 1 teaspoon onion powder
- 2 tablespoon chopped fresh rosemary
- 2 tablespoon chopped fresh parsley
Instructions
- Add sweet potato chunks to large saucepan or dutch oven and cover with 3 inches of water.
- Place lid on and let potatoes cook over medium-high heat for 25-30 minutes or until fork tender.

- Using a potato masher, mash until desired texture. I like to do this for several minutes until it is very soft.
- Add salt and pepper to taste. Serve with butter.
- Cut Potatoes Small: Cut the sweet potatoes into smaller chunks before boiling so they cook faster and become perfectly fork tender. It makes the whole process way easier when it’s time to mash everything together.
- Mash Until Creamy: Mash the potatoes for several minutes if you want that super soft, fluffy texture. Don’t rush it — the extra mashing helps create that ultra creamy consistency.
- Don’t Skip the Greek Yogurt: The Greek yogurt adds a creamy texture without making the potatoes heavy, and the flavor blends right in with the butter, garlic, rosemary, and seasonings.

These are seriously the best mashed potatoes I have ever made or eaten! I didn’t have enough sweet potatoes, so I did a sweet and white potato blend, and I had to sub thyme for rosemary, but I’m they have similar flavor profiles so I can only imagine what the rosemary will be like! I could have eaten the whole bowl! Amazing!
