Equipment

  • High-power blender

Ingredients

  • 1 pint cherry tomatoes
  • 2 red bell peppers
  • 1 medium carrot
  • 1 medium onion
  • 3 cloves garlic
  • 3 tablespoon olive oil
  • ½ teaspoon salt
  • 1 teaspoon hot peppers in oil also known as hot bomba spread
  • 1 teaspoon red pepper flakes
  • Large handful of basil leaves
  • 1 lb pasta of choice I recommend rigatoni

Instructions

  • Preheat the oven to 400ºF.
  • Peel the carrot and chop the red bell peppers, carrot, and onion into medium size chunks. Add to a baking sheet with the cherry tomatoes and 3 peeled cloves of garlic. Drizzle with olive oil and a good pinch of salt. Mix until coated then roast for 30-40 minutes until tender, stirring halfway.
  • Allow the roasted veggies to cool for 10 minutes. During this time, boil a large pot of water on the stove, add a good pinch of salt, and cook the pasta according to package instructions.
  • Scoop the roasted veggies into the bucket of a large blender*. Add 1 cup water, the hot pepper spread, red pepper flakes, and basil leaves. Leave the steam vent open on the lid of the blender, and cover with a dish cloth. Carefully blend for 60 seconds on medium-high until pulverized. Taste the sauce and add salt if necessary.
  • Save 1 cup of the pasta cooking water then drain the rest. Add the pasta back to the pot and pour the blended sauce and a small amount of pasta water. Mix gently to combine. Add pasta water as needed to thin out the sauce.
  • Serve topped with extra pepper flakes, basil, and parmesan cheese if desired.

Notes

*Do not blend hot liquid in a bullet-style blender, as it is dangerous. Allow veggies to cool completely or use a large bucket style blender with the steam vent opened and covered with a cloth. 
  • Use any veggies you have on hand to create a delicious sauce.
  • Store leftover pasta sauce in an airtight container in the fridge for up to 4 days. Heat and add to fresh pasta. Or freeze the pasta sauce for up to 3 months. Thaw on the counter for a few hours or in the fridge overnight before heating.
