Ingredients for Mashed Sweet Potatoes with Rosemary and Parmesan
Here’s what you’ll need to make these savory mashed sweet potatoes. Exact amounts are listed in the recipe card below.
- Sweet potatoes – Cut into similar-sized pieces so they cook evenly.
- Butter – Helps the mash stay smooth and creamy.
- Parmesan cheese – Adds a savory boost and blends easily into the warm potatoes.
- Rosemary – Fresh and finely chopped, so it mixes in evenly.
- Seasonings – Garlic powder, salt, and black pepper to round out the flavor.
Optional Add-Ins
- Use whatever fresh herbs you prefer. I use rosemary because it reminds me of Thanksgiving. Fresh thyme or fresh chives would also be a great addition to this recipe.
How to Make Mashed Sweet Potatoes with Rosemary and Parmesan
STEP ONE: Cook the Potatoes. Place cubed sweet potatoes into a large pot over medium-high heat. Fill with enough water to cover the potatoes by 1 inch. Bring to a boil and cook for about 20 minutes or until fork-tender. (Cooking time may vary depending on the size of your potato chunks.) Drain the potatoes and return them to the pot.
STEP TWO: Add Butter, Parmesan, Herbs, and Seasonings. Off heat, add the butter, Parmesan cheese, rosemary, garlic powder, salt, and black pepper. Using a potato masher or electric hand mixer on low speed, mash or blend to your desired consistency.
STEP THREE: Serve. Adjust seasoning to taste, transfer to a serving bowl, and serve hot.
Make It Vegan 🌱
For a plant-based dish, use dairy-free butter and Parmesan cheese.
Recipe FAQs
Can I make these ahead for the holidays?
- Yes. Prepare one to two days in advance, refrigerate, and reheat with a splash of broth or milk to loosen the texture.
Do I have to peel the sweet potatoes?
- No, you don’t. Peeling gives a smoother mash while leaving the skins on creates a more rustic texture, so go with whatever suits your style.
How do I make the potatoes extra smooth?
- Use a hand mixer on low speed and add a tablespoon or two of milk until they reach your preferred consistency.
Can I use different herbs in this recipe?
- Yes. Rosemary is the main flavor here, but thyme or chives would also blend in easily and keep the mash savory.
Storage and Reheating
- Store leftovers in an airtight container in the refrigerator. Reheat on the stovetop over low heat, stirring in a splash of milk or broth until smooth again.
