One-Pot Penne with Sausage, Pumpkin, and Fennel

I got this from Food52 and was drawn to it because I had a can of pumpkin leftover from holiday baking. It's DELICIOUS and takes very little time to make.

1 tbsp olive oil
1 small to medium fennel bulb, chopped
1 large carrot, chopped
1 medium onion, chopped
2 cloves garlic, minced
1/2 tsp red pepper flakes
2 links of Italian sausage, casings removed
1 fresh sage leaf or 1/2 tsp dried sage
1/2 cup dry white wine (or 1/4 cup lemon juice + 1/4 cup water)
2 1/2 cups chicken stock
3 cups dried penne
3/4 cup canned pumpkin
1/2 lemon juiced
1/2 cup Parmesan
1/4 chopped parsley if you have it

1. In a large skillet, heat the olive oil on medium high and cook the carrot, fennel, onion and garlic until softened. Add the sausage and cook through, crumble it up as it cooks.

2. Add the sage and wine and deglaze the pan and reduce the wine by 1/2. Add the stock and penne and make sure the penne is in or under the stock. Bring to a low boil, cover, and cook for 7 mins.

3. Add the pumpkin and lemon juice, stir to combine. Cover and cook another 3 mins or until the pasta is cooked through. Add the Parmesan and stir well.
