Ingredient Notes

Butternut Squash Mushroom Pasta ingredients on a light gray background.
  • Penne: You don’t have to use penne. Feel free to use your favorite pasta or any you have on hand. I would recommend a pasta similar to penne and not use a long pasta like spaghetti for linguini. 
  • Italian Sausage: Casings removed. You can use the Italian sausage that is in casings or your local grocery store may sell the tubes of ground Italian sausage. You can also use spicy sausage instead if you’d prefer more spice in the pasta dish.
  • Butternut Squash: Be sure to peel the squash, remove the pulp inside and cut into small cubes. This will help the squash cook more quickly. 
  • White Mushrooms: If you aren’t a fan of mushrooms, you can omit the mushrooms or sub them out for something else.
  • Red Pepper Flakes: This is just a tiny amount so it won’t provide much heat at all. If you want more heat, add more red pepper flakes! 
  • Unsalted Butter: This is for the brown butter sauce. If you have any questions about browning butter, then my Brown Butter Recipe will be a big help! 
  • Fresh Sage Leaves: Butternut squash with sage is one of my favorite flavor combinations! You’ll get a stronger and more prominent flavor from the sage if it is fresh. 

Step-by-Step Instructions

  1. Brown the sausage. Cook the sausage in a large skillet over medium heat, breaking up the meat as you go. Once fully cooked, use a slotted spoon to transfer to a paper towel-lined plate. Drain excess grease.
  2. Cook the butternut squash. Add a tablespoon of olive oil to the empty skillet. Add the cubed butternut squash and cook for about 8 minutes. Season with sat and pepper. Add the mushrooms, garlic and red pepper flakes. Cook until the squash is fork tender and the mushrooms are softened and browned. 
  3. Cook the pasta. While the squash is cooking, bring a large pot of salted water to boil. Add the penne and cook until al dente. Drain (but reserve 1 1/2 cup of the pasta water!).

  1. Combine veggies and noodles. Now that you have the cooked pasta and the water has been drained from the noodles, add the sausage, butternut squash and mushroom mixture to the pot of noodles.
  2. Make the brown butter sage sauce. Follow my How to Brown Butter recipe to brown the butter. Once the butter is browned, remove the skillet from the heat and add the fresh sage leaves. Pour the brown butter sage sauce over the pasta and stir to combine. Add 1 cup of the additional pasta water to loosen up the mixture (add more if needed).
  3. Serve! Serve this butternut squash sausage pasta with fresh parmesan cheese. Enjoy!

Recipe Tips

Feel free to use a different pasta. Bowtie, rigatoni or ziti would all be great options! 

If you are having problems telling if the butter has been browned, using a white pan can help so you can see the butter browning. 

If you aren’t a mushroom fan, feel free to omit them. I didn’t grow up eating mushrooms because my mom doesn’t like them, but since leaving the house I’ve come to love them! I hope you will too 🙂

Make Ahead, Storing, and Freezing

You can make brown butter ahead of time and store it in the fridge in an airtight container for 3-4 days prior to making the butternut squash with sage recipe. Just give the butter a turn in the microwave to return to a liquid state and add the fresh sage. 

Store any leftover butternut squash sausage pasta in an airtight container in the fridge for 4-5 days. 

I don’t recommend freezing the butternut squash mushroom pasta because I will get mushy. However, if you’d like to freeze the butternut squash mushroom and sausage mixture, you can. Store it in an airtight container or freezer safe bag in the freezer for up to 2 months. Remove and let thaw in the fridge overnight. Then continue with the recipe from that point.

Recipe FAQs

What is browned butter?

Brown butter is the process of cooking the butter to separate the milk solids and brown those! Browned butter has a nutty aroma to it and the overall color of successfully browned butter is a golden amber color.

Can I use a different squash?

Sure, but I would probably only use acorn squash or another winter squash if you were to use a different squash. Otherwise you won’t get the right type of flavor or texture. 

Why is my butternut squash crunchy?

You probably didn’t cook it long enough. Also, be sure to cut the butternut squash into small cubes. This will help the squash cook quicker.

Butternut Squash Mushroom Pasta

This butternut squash pasta dish is the perfect fall meal. It’s EASY to make and absolutely delicious. The pasta is full of sweet Italian sausage, butternut squash, mushrooms, and covered with a browned butter and sage sauce.
Prep Time: 10 minutes
Cook Time: 30 minutes
Total Time: 40 minutes
Servings: 10 servings


  • 1 lb penne
  • 1 lb sweet Italian sausage - casings removed
  • 1 tablespoon olive oil
  • 4 (heaping) cups butternut squash - diced into 1/2-1 inch cubes.
  • 10 oz white mushrooms - sliced
  • 2 garlic cloves - minced
  • 1/4 teaspoon red pepper flakes
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper
  • 6 tablespoons unsalted butter
  • 10 fresh sage leaves
  • 1 cup freshly grated parmesan


  • Bring a large pot of water to boil. Once boiling, add 1 T of kosher salt. Add the pasta to the boiling water and cook until al dente. Drain the water. Reserving 1 ½ cups of pasta water.
  • While the pasta is cooking, grab a skillet and brown the sausage over medium heat. Breaking up the sausage into little pieces with a wooden spoon. Cook until no longer pink. Use a slotted spoon and transfer the sausage to a paper towel lined plate. 
  • Discard the sausage drippings, if any. 
  • Add 1 tablespoon of olive oil to the now empty skillet. Add the cubed butternut squash to the skillet. Sprinkle the squash with the salt and pepper. Cook for 8 minutes or so. Add the mushrooms, garlic, and red pepper flakes. Cook until fork tender and the mushrooms have softened and browned. About 3-4 more minutes. Transfer the cooked squash and mushrooms to the pot with the drained pasta.
  • Add the butter to the skillet. Cook over medium-low heat, whisking constantly. The butter will begin to foam and then small golden specks will appear towards the bottom of the skillet. (Easiest to use a white colored skillet if possible). The butter will have a nice nutty aroma to it. 
  • Remove the butter from the heat. Add the sage leaves to the butter and stir. 
  • Add the sausage and butternut squash to the pasta. Pour the sage butter overtop and mix everything to combine. Sprinkle the parmesan overtop and stir to incorporate. Add pasta water to loosen up the noodles. I added about 1 cup of the pasta water to the pasta. You can gauge how much you’d like to add. 
  • Serve immediately.


Store leftovers in an airtight container in the fridge for 4-5 days.
