This recipe for Vegan Roasted Red Pepper Pasta Sauce is made with aromatic, sweet oven-roasted red peppers, roasted garlic, cashews, and shallots. It’s bursting with flavor because of the addition of herby fresh basil leaves and a splash of lemon juice.
Adding vegetable broth makes the sauce the perfect creamy texture to smother on top of your favorite pasta. Make this sauce for a wholesome and vibrant pasta dinner.
Roasting the red peppers for your vegan red pepper pasta is very simple and easy:
- First, wash and slice the red bell peppers lengthwise. Remove all the seeds and membranes inside. Discard the stem as well.
- Place the peppers cut-side down on a baking sheet and brush with olive oil.
- Bake at 425°F (220°C) for about 30-40 minutes. You’ll see the skins of the peppers start to char a little bit, this is when you know they are done.
- After the peppers are roasted, transfer them to a heat-safe bowl and cover with a towel. Let them steam for about 10-15 minutes, or until they are cool enough to handle.
- Once steamed, it should be easy to peel the skins off the peppers. Now, they are ready to blend into a creamy, dreamy, sauce with the addition of a few other ingredients.

Unfortunately I’m intolerant to cashews. Is there another type of nut I could use?
Hi Evan, you may want to try just omitting the cashews completely.
Delicious recipe! Thank you!
Loved this recipe! Used jarred bell peppers and omitted the oil and shallots as well since I didn’t have any. It came together in a snap and is excellent!! Thank you for posting this recipe!!!
I’d like you know how much is one cup? Thankyou!
What’s your favorite vegetable broth brand?
Delicious recipe! I used jarred roasted peppers instead. I like my pasta saucy and looking it over I didn’t think I’d have as much as I’d like so I doubled the recipe and it was just right. I sautéed some spinach and blended it in there too for some hidden veggies, then topped with sautéed mushrooms. Thanks!
I’ve made this 3 x already. So creamy and delish!
Thank you so much for letting us know! Glad you love it 🙂
I cooked the sauce with minimal changes:
Substituted cashews with macadamia nuts and added more garlic. It was delicious and I will make this sauce again! Thank you for sharing it!!!
I am not sure about the cashews. Do I just buy them in a can without salt one them or raw cashews? Thank you, Linda
The cashews are raw (unsalted).
