The sweetness of the caramelized onion goes great with the bold garlic and bright fresh parsley finish on this pasta. This is some serious plant-based comfort food!

How Do I Make This Caramelized Onion Pasta Recipe?

  1. Caramelize the Onions: In a Dutch Oven or other heavy lidded pot, add the onions, olive oil, and sea salt.  Saute on low heat, and stir with a wooden spoon for 25 minutes until the onions begin to reduce. After 25 minutes, add the vegan Worcestershire sauce and saute for 5 additional minutes.
  2. Cook pasta according to package instructions.  Save 1 cup of the pasta water and set aside.
  3. While pasta is cooking, in a large pot heat olive oil over low heat. Add the garlic and saute for 2 or 3 minutes until the garlic begins to brown. Sprinkle in the flour/corn starch and stir until a thick paste forms.
  4. Add the oat milk, garlic salt and pepper, and stir.  Add the caramelized onions and pasta to the sauce and top with parsley.  If sauce is too thick, add the cooked pasta water 1/4 cup at a time until the sauce is the consistency you prefer.  If sauce is too thin, add an additional tablespoon of flour or corn starch until it reaches desired consistency.

  • Caramelize the Onions: In a Dutch Oven or other heavy lidded pot, add the onions, olive oil, and sea salt.  Saute on low heat, and stir with a wooden spoon for 25 minutes until the onions begin to reduce. After 25 minutes, add the vegan Worcestershire sauce and saute for 5 additional minutes.
  • Cook pasta according to package instructions.  Save 1 cup of the pasta water and set aside.
  • While pasta is cooking, in a large pot heat olive oil over low heat. Add the garlic and saute for 2 or 3 minutes until the garlic begins to brown. Sprinkle in the flour/corn starch and stir until a thick paste forms.
  • Add the oat milk, garlic salt and pepper, and stir.  Add the caramelized onions and pasta to the sauce and top with parsley.  If sauce is too thick, add the cooked pasta water 1/4 cup at a time until the sauce is the consistency you prefer.  If sauce is too thin, add an additional tablespoon of flour or corn starch until it reaches desired consistency.

Notes

To Make Your Own Unsweetened Oat Milk:
  1. .Combine 1 cup oats, 4 cups water, and pinch of salt to a blender.  Allow the ingredients to sit for 10 minutes before blending.
  2. Blend on high for 30 seconds.  Strain immediently though a fine mesh strainer, cheese cloth, or a nut milk bag. Do NOT squeeze the oat milk, let it drain naturally. Squeezing it can cause it to become slimy.
To thicken your sauce: add 1 tablespoon of water to 1 teaspoon of cornstarch in a seperate bowl, mix well to combine. Add corn starch mixture to the pasta sauce while it is warming and stir for a minute or two until it thickens.
