What’s In This Alfredo with Caramelized Onions?
- Onions: sliced into thin even strings
- Gluten Free Linguine: I used a long linguine pasta, but you can use fettuccine, spaghetti, angel hair, bucatini,or any other long pasta shape! If you aren’t gluten free you can use a normal or wheat pasta instead.
- Olive Oil: I like to use this fruity Zoe olive oil which has a fantastic flavor and deep color- it’s really inexpensive online here, so I keep a few liters stocked up in my pantry. For the quality of oil you get, it’s an excellent value, I would highly recommend!
- Garlic: you can use fresh garlic if you have it, or heirloom jarred garlic if you are making this pantry-staple friendly.
- Flour or Corn Starch: use a gluten free flour or corn starch to form a roux. The roux will thicken the sauce making this an irresistible creamy and luscious pasta dish!
- Plant Based Milk: I love this shelf stable almond milk... just make sure to use unsweetened/unflavored!
- Garlic Salt: for a little extra flavor and spice in this pasta.
- Fresh Ground Pepper: I use tellicherry pepper corns because they have a nice flavor with a hint of spice, and are a great value for the quality of fresh pepper corns.
- Parsley: to give the alfredo pasta sauce a bright fresh finish.

How Do I Make This Caramelized Onion Pasta Recipe?
- 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.
