Instructions

Preheat oven to 425˚F. Peel the sweet potato and celeriac then cut into ½” cubes. Toss with the olive oil, salt, and pepper. Spread onto a sheet tray and roast until the vegetables are tender and starting to brown; 30 to 35 minutes.
While the sweet potatoes are roasting, cook the pasta until tender. Drain and reserve ½ cup of pasta water. Set pasta aside.
Return the pan used for pasta back to the stovetop. Over medium-low heat, add the butter and let melt. Add the hazelnuts and cook for a couple minutes, until fragrant. Stir in the garlic and continue to cook for another minute; just long enough for the garlic to become golden. Turn off the heat and stir in the lemon juice, zest, tarragon, and salt.
Add in the roasted sweet potatoes and pasta; tossing until well combined. Add a splash of pasta water as needed to help the butter coat the noodles. This may or may not be needed. Serve with a sprinkle of chopped hazelnuts and minced tarragon if desired.

Notes

Tip + Tricks: Make the sweet potato mixture ahead of time and let it warm with the butter sauce. This will help cut-down the day-off time.
