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
- Roast your peppers or pick up some roasted red peppers packed in water.
- Add all sauce ingredients to a blender and blitz until smooth.
- Cook pasta and toss with sauce!
How To Roast Red Peppers
Step 1
Preheat the oven to 450ºF. Place the whole peppers on a sheet pan lines with parchment. Place in the oven.
Step 2
Rotate the peppers every 15 minutes. You want all sides to be charred and black. Your kitchen will smell delicious!
Step 3
When done, remove from the oven and place in a heat-proof bowl. Cover with a plate to let the peppers cool. The steam will loosen the skins.
Step 4
Once cooled, remove the skins, stem, and seeds and your roasted peppers are ready!
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.

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 : )
