Butternut Squash Pasta Sauce Recipe


  • 1 bell pepper (small diced)
  • 1 small to medium onion (small diced)
  • 1 tablespoon olive oil
  • 1 tablespoon butter
  • 1 1/2 teaspoon kosher salt (divided)
  • 1/2 teaspoon black pepper
  • 1 can butternut squash puree (15 ounces)
  • 1 teaspoon minced rosemary (plus more to finish bowls)
  • 3/4 cups chicken or vegetable stock
  • 1/4 cup pasta water
  • 1/4 - 1/2 cup heavy cream
  • 1 teaspoon balsamic or red wine vinegar
  • cheese tortellini or pasta of your choice


Step 1
Melt 1Tbs of butter and 1Tbs olive oil in a skillet over medium heat.

Dump in the diced onion and bell pepper, along with 1/2 tsp each of salt and pepper.
Step 2
Saute about 5 minutes or until softened.
Step 3
Now comes the real time saver in the form of canned butternut squash.
Step 4
Don't be scared. It's good; I promise.

Anyone who's ever thought about adding butternut squash to a weeknight meal then reconsidered because it's a royal pain in the ass and takes too long should seriously try this.

Anyway, scrape all the yummy squash out of the can and onto your onions and peppers. Sprinkle on the rosemary,
Step 5
and mix everything together to make an onion studded paste.
Step 6
Pour in the broth and pasta water, and carefully stir to incorporate them into the sauce. Or if you're me, stir vigorously until some slops out of the pan, and THEN stir it carefully.
Step 7
Reduce the sauce slightly at a simmer for about 5 minutes.

Add anywhere from 1/4 to 1/2 cup of heavy cream depending on your taste.
Step 8
We went heavier and added 1/2 c heavy cream. You could definitely go lighter and only add a splash.

If you only add a touch, I'd do it off the heat and add the vinegar at the same time. However, if you add a full 1/2 c like we did, I'd keep the sauce over medium low heat for a few more minutes to let it reduce just a touch more.

Once the sauce looks deliciously smooth and creamy, add a splash of your favorite vinegar to finish it off.
Step 9
Brian always goes balsamic when given the choice, so we opted for one of our favorites... Benissimo Barrel Aged Balsamic Vinegar.

A touch of vinegar adds just enough acidity to help develop all of the flavors in the sauce.

I think any number of vinegars would work great here. Red wine, champagne, sherry, or apple cider vinegars are all fine choices.
Step 10
In less than half an hour, you've got a satisfyingly creamy pasta sauce that's healthier AND tastier than boxed mac and cheese!
