Butternut Squash “Carbonara” with Veggies

If you like to repurpose leftovers like I do, this is the perfect recipe for the butternut squash soup you made a couple nights ago! Add in some veggies, and the pasta of your choice, and you’ve got a whole new dish. When I make this, I like to use spaghetti noodles, and whatever else I have in the fridge. The resulting dish is usually like a carbonara style pasta with unique and very satisfying flavors. If you’d like to make a vegetarian version of this dish, just leave out the bacon and cook everything with butter or olive oil instead of bacon fat.

Ingredients

  • 1 lb spaghetti noodles, or pasta of your choice
  • 1 c reserved pasta water
  • 4-6 slices bacon (leave this out for a vegetarian option, and substitute butter or olive oil for bacon fat)
  • 2 tbsp minced garlic
  • ¼ tsp red pepper flakes (adjust to fit your taste preferences)
  • 1 sweet onion, chopped
  • 1 c grape or cherry tomatoes, halved
  • 1 c spinach, roughly chopped
  • ½ tsp salt
  • ½ tsp pepper
  • ¼-½ c grated parmesan cheese, plus more for garnish
  • 1½-2 c butternut squash soup

Instructions

  • Set a pot of boiling water over high heat, and prepare pasta according to package instructions. Remember to reserve about 1c of pasta water before draining. Set aside pasta and reserved water.
  • While water is heating up, set a large frying pan over medium heat. Cook bacon, and set aside. Leave the bacon fat in the pan.
  • Lower the heat to medium, let the pan cool just slightly so you don't burn your garlic. Add garlic and red pepper flakes to the bacon fat, and fry until the garlic is golden brown. It takes about 30 seconds, so keep stirring and watching so it doesn't burn. When garlic is fragrant and golden, add onion. Sauté for about 5 minutes.
  • Add tomatoes to the pan, and sauté for 2-3 minutes until they begin to soften. Add spinach, and continue to sauté until it's wilted and incorporated with the rest of your mixture.
  • Season with salt and pepper, add parmesan cheese, 1-1½c of the butternut squash soup, and ¼-½c of reserved pasta water. Stir to combine all ingredients and bring to a simmer. Allow to simmer for a few minutes, so the cheese has time to melt into the sauce. Add noodles, and stir.
  • Add more butternut squash soup if your mixture is looking dry. If your sauce is too thick, add a bit more of the reserved pasta water. Continue to adjust consistency and volume of sauce to fit your preferences, by adding more of the soup and splashes of pasta water. Your end result should be a creamy sauce, reminiscent of an alfredo or carbonara sauce. See notes for additional information about achieving your desired results.
  • Crumble bacon over the finished pasta, and stir. Adjust salt and pepper as needed, and serve topped with grated parmesan cheese.

Notes

Making this sauce is not an exact science. It’ll take some eyeballing, but I promise you’re not going to break the recipe.
If your mixture looks too dry, you need more sauce, so let’s evaluate two scenarios and how to achieve them:
    1. Noodles look dry, and you want more sauce: add more butternut squash soup. Stir, and add a splash of pasta water to help thin the sauce if it’s looking too thick. Continue to do this until your desired sauce to pasta ratio is achieved
    2. Noodles look dry, and you want to achieve more of a carbonara style dish: add more parmesan cheese (maybe 1/4c), and a tablespoon or two of pasta water/butternut squash soup combo. To make this combo, just add equal parts of soup and pasta water, and stir to make a “slurry”. Add this to the pasta, stir, and evaluate consistency.
