Sage & Brown Butter Mashed Sweet Potatoes – Sweet Potatoes are mashed together with chopped sage and browned butter.

Sweet Potatoes mashed together with chopped sage and browned butter.

Thanksgiving is just a few days away. Can you believe it?! This year has been so odd. Staying at home so much has me all confused about the seasons and holidays. It feels like Thanksgiving has come out of nowhere!

Earlier this year, I talk about how underappreciated sweet potatoes are. So I am doing my part to highlight the various ways you can enjoy them, aside from simply baking them.

For today’s recipe, I am combining sweet potatoes with a savory pairing of sage and brown butter. These flavors go incredibly well with sweet potatoes, as I’ve highlighted in these hasselback potatoes and these sweet potato gnocchi. Now, I am combining those flavors into a simple mashed sweet potato recipe that can easily be made for any weeknight meal, but also is perfect for the all-important Thanksgiving meal.

I present to you my Sage & Brown Butter Mashed Sweet Potatoes!

How to make these mashed sweet potatoes

These mashed sweet potatoes are made in three main steps:

  1. Boil sweet potatoes
  2. Make sage and brown butter mixture
  3. Mash everything together
Boil Sweet Potatoes

Before boiling the sweet potatoes, you want to peel them. The skin on sweet potatoes is pretty tough so it won’t taste good in the mashed sweet potatoes. Then, you’ll want to cut into big chunks. Don’t make them too small or else they will absorb too much water and make the potatoes too liquidy.

Once you have cut the potatoes, add to a big pot and fill with water and a little salt. Then boil until they get tender.

Sage & Brown Butter Sauce

The sage and brown butter give the sweet potatoes all their flavor. To make the sauce, you simply brown butter over medium heat until it smells nutty and rich. Then, remove from the heat and add the chopped sage, more butter, and heavy cream.

Mashing Everything Together

Once both components are ready, it’s time to mash them together. I use my stand mixer to mash potatoes but you can use a potato masher or even a food mill (if you want them extra creamy).

The sweet potatoes are added to the bowl of a stand mixer, along with the brown butter sauce. Using a paddle attachment, everything is mashed together until creamy. And then they are ready for serving!

Tips & Tricks

  1. Because butter is so important in this recipe, you must use good-quality butter. Therefore, spend a little extra on that fancy, European-style butter. I promise you won’t be disappointed.
  2. When boiling potatoes, you need to boil them differently than you would boil, let’s say, pasta. That is, you need to add the cut potatoes to a pot, add enough cold water to just cover the potatoes, and then bring to a boil. This ensures the potatoes cook evenly and efficiently.
  3. Be careful adding the heavy cream to the brown butter. Since the cream is much colder than the hot butter, it will bubble up when added to the butter. So it’s best to add it slowly.

Sage & Brown Butter Mashed Sweet Potatoes

Prep Time10 minutes mins
Cook Time30 minutes mins
Total Time40 minutes mins
Servings: 6 servings

Ingredients

  • 3 pounds sweet potatoes peeled and quartered
  • 6 tablespoons butter divided
  • 2 teaspoons chopped fresh sage leaves
  • ⅓ cup heavy cream
  • 2 teaspoons salt plus more for potato water

Instructions

  • Add potatoes to a large pot and fill pot with water, just enough to cover the potatoes. Salt the water with a tablespoon of salt. Cover and bring water to a boil. Once boiling, remove cover and cook for another 15 to 20 minutes, or until potatoes are very tender.
  • While the potatoes boil, add 3 tablespoons of butter to a small sauce pan. Place over medium heat and cook until butter browns, but doesn't burn. Remove from heat and add sage, remaining butter, and heavy cream. Set aside.
  • Remove potatoes from water (but do not discard the water!) and place into bowl of stand mixer. Add butter and cream mixture. Pulse mixer with paddle attachment to mash the potatoes. If you don't have a stand mixer, simply use a potato masher to achieve this.
  • Once potatoes are mashed, add 1 or 2 teaspoons of salt (to taste). Mix on low to combine, or use a wooden spoon to combine. If potatoes are too dry, add a little of the reserved potato water until desired consistency is reached. Place in serving dish and serve immediately.

    Made this recipe for Thanksgiving and it was a huge success. We love our sweet potatoes and can’t figure out why people have to add additional sweetness to their natural sweetness. The nuttiness of the brown butter worked splendidly with the sage. Luckily we still had sage growing outside.

Peach Raspberry Cobbler – fresh peaches and rasp Peach Raspberry Cobbler – fresh peaches and raspberries topped with a cakey, cinnamon-sugar crust that's so incredible you won't even need ice cream!

Cobblers have stolen my heart, you guys! The first cobbler I ever loved was blackberry, but after tasting this peach raspberry version at a work potluck, it took the top spot! 

The secret? That cinnamon sugar crust! It's not just a topping – it's the STAR of the show! The combination of fresh peaches, tart raspberries, and that cakey, cinnamon-sugar-coated crust is pure summer magic!

Pro tip: Let the cobbler cool for at least 15 minutes before serving so the filling can thicken up and it'll be much easier to scoop!

Perfect for summer gatherings, July 4th parties, potlucks, or anytime you want a Southern dessert with a delicious twist!

Nutella Macarons – delicate French almond cookie Nutella Macarons – delicate French almond cookies filled with chocolate-hazelnut Nutella spread! Classic macarons made with the proper technique learned straight from a pastry chef! 

You guys remember when I made French macarons for the first time and they were a HOT MESS? The tops were cracked and bumpy and looked more like brownies! I was determined to get them right, so I took a macaron baking class in person – and it changed EVERYTHING! 

The trickiest part? Mixing the dry and wet ingredients together. Under mix = too dry and cracked. Over mix = dense and heavy. But now I know exactly what the batter should look like!

Pro tip: Age your egg whites for 24-48 hours before making the meringue – this helps them get to the perfect consistency!

Perfect for Valentine's Day, gift-giving, special occasions, or anytime you want elegant French macarons at home! 🇫🇷

Classic Pot Roast – chuck roast slowly cooked in Classic Pot Roast – chuck roast slowly cooked in a jus made of beef broth, carrots, celery, and onions! Balsamic vinegar, thyme, and mustard give that jus a kick of flavor! 

Cold weather is in full effect, you guys! So comfort food needs to be on the menu! My husband wanted to try a good pot roast, so I used a combination of recipes to come up with the perfect one! 

The secret? Traditional aromatics (carrots, celery, onions) PLUS balsamic vinegar and Dijon mustard set this roast apart with a tangy kick!

Pro tip: Sear the roast first to give it beautiful color on the outside – if you skip this step, the meat will look almost gray when cooked in the broth!

Sweet Potato Gnocchi with Sage Browned Butter – Sweet Potato Gnocchi with Sage Browned Butter – fluffy pillows of sweet potato dumplings tossed in a sage and browned butter sauce for a comforting pasta dish you didn't know you needed! 

This gnocchi was inspired by a dish I had at a local restaurant years ago, you guys! I was skeptical about sweet potato gnocchi with just butter and sage – no cream? no tomato? But MAN, was I wrong! 

The sweet potato gnocchi is even MORE flavorful than the original! It shines on its own with little help from a heavy sauce – that's why it pairs so perfectly with a light toss in sage and browned butter!

Pro tip: Use a potato ricer to break up the sweet potatoes – don't use a food processor or it will make the gnocchi gummy and pasty! The ricer makes it super fluffy!

Perfect for fall dinners, Thanksgiving, date nights, or anytime you want restaurant-quality comfort food at home!

I fell in love with these at a local bakery, and now my husband surprises me with them from time to time! Do I have a great man or what?!
