Vegan Roasted Red Pepper Pasta


About This Vegan Roasted Red Pepper Pasta

This roasted red pepper pasta sauce (oil-free and made in a blender) is out of this freakin’ world! 

I am serious about this pasta! I like to use hot water or broth when I’m making this sauce just before serving. But if I’m making this ahead of time I use refrigerated or room temp water/broth. 

And I also like the sauce a little on the thick side and prefer to thin it as needed with starchy pasta water.

The secret to this amazing sauce? Roasting your own peppers which is so easy! See below.

Ingredients You'll Need

  • any pasta (type and shape you like)
  • cashews
  • roasted red peppers (about 2)
  • garlic
  • lemon
  • nutritional yeast
  • dried oregano
  • onion powder
  • crushed red pepper flakes
  • ground nutmeg
  • salt and pepper
  • water or vegetable broth

How To Make

  1. Roast your peppers or pick up some roasted red peppers packed in water.
  2. Add all sauce ingredients to a blender and blitz until smooth. 
  3. Cook pasta and toss with sauce!

How To Roast Red Peppers

Tips & Tricks

  • Roast your peppers ahead of time and keep in the fridge until needed.
  • If using jarred roasted red peppers, be sure to choose red peppers packed in water and not oil. 
  • Add veggies like cauliflower or broccoli in with the pasta while it’s simmering. Cauliflower will need about 5 minutes of cooking time and broccoli about 3 minutes (depending on size of florets).
  • Use leftover vegan roasted red pepper pasta sauce as a grain bowl sauce or drizzle on steamed veggies.

An amazing oil-free, flavour packed sauce that pairs with any pasta and veggie! Cooking time does not include roasting peppers or soaking cashews.




  • 12 ounces (340 grams) brown rice, whole wheat, quinoa, or legume pasta, any shape you like
  • ¾ cup cashews (unsalted and unroasted) soaked for 1 to 3 hours in water*
  • ¾ cup roasted red peppers , about 2 roasted red peppers, peeled, seeds and stems removed **
  • 2 large garlic cloves
  • Juice of ½ lemon
  • 1 tablespoon nutritional yeast
  • ¾ teaspoon dried oregano
  • ¼ teaspoon onion powder
  • ¼ - ½ crushed red pepper flakes , depending on how spicy you like it
  • Pinch ground nutmeg
  • ¾ teaspoon sea salt or to taste
  • Pinch black pepper or to taste
  • ¾ cup hot water or vegetable broth* plus more as needed
  • For serving: Sliced black olives, fresh herbs, microgreens


  • Bring a large pot of salted water to a boil. Once boiling add the pasta and cook until al dente.
  • Meanwhile, drain the cashews and add them to a blender along with all other ingredients. Blend until completely smooth and add more liquid as needed (water or broth). Taste and reseason as needed with salt and black pepper
  • When the pasta is done, reserve about ½ cup of pasta cooking liquid then drain, rinse the pasta with running water, and return the pasta back to the pot. Pour the desired amount of sauce onto the pasta and toss with tongs to mix. Keep adding more sauce until it’s how you like it. Use the remaining pasta water to thin if needed.


*Soaking cashews: You can get away with not soaking your cashews if you have a highspeed blender. 
**Roast your own peppers! It's easy and way more delicious. See post for how-to!
Adding veggies: I generally serve this pasta with roasted or sautéed veggies. Try sautéed mushrooms and onions or roasted cauliflower or steamed broccoli.
Adding beans: Add a can (drained and rinsed) of chickpeas to this roasted red pepper pasta.
Leftover sauce will keep in the fridge for up to 5 days. It will also thicken as it sits. Just give it a little stir or add extra warm liquid to loosen.

    Amazing sauce!! I just made it and it was soooo good! There is nothing that I’ve tried so far from the cookbook or the website that I did not like. I added roasted cauliflower and chickpeas as suggested to make it a complete meal, let me tell you it was one of the easiest and most delicious meals I’ve had since I started my WFPB journey a year ago. Thank you, Ashley! Love your recipes : )
