This Roasted Red Pepper Sauce is so delicious and easy to make! I use it with my Nachos recipe, but it can also be served on baked potatoes, rice or pasta. Since I don’t use nutritional yeast (see Notes), I wanted to create a flavorful, colorful cheesy sauce that could take the place of common vegan cheese sauces. Enjoy!
PrintRoasted Red Pepper Sauce
- Total Time: 40 minutes
- Yield: makes 1.75 cups 1x
Ingredients
- ½ cup water
- ½ cup (2 ounces) raw, unsalted cashews (or see Notes)
- 1 medium red bell pepper, halved and seeded
- ½ medium red onion, cut in half again
- 4 medium garlic cloves, peeled
- ¼ teaspoon chipotle powder
Instructions
- Place the cashews and water into a blender, and blend for 10 seconds. Let sit so the nuts can soften. Preheat the oven to 400F.
- Line a baking pan or sheet with parchment paper (or use a silicone mat). Place the two pieces of red onion on the pan as well as the bell pepper halves cut side down. Place two garlic cloves under each pepper half. Roast for 25 to 30 minutes (on the center oven rack), or until the bell peppers start to wrinkle and brown (see photo).
- Add the roasted bell pepper halves, red onion pieces, and garlic cloves to the blender of cashews and water; also add the chipotle powder. Blend until smooth. Add a little water as needed to thin. Reheat the sauce in a small saucepan if desired.
Notes
Cashew substitutes: Cashews are my favorite fat source for creamy sauces, but if you can’t eat them, use another nut or seed. Cooked white potatoes, like Yukon Gold, may work too, but the sauce would not be as rich since potatoes are much lower in fat than nuts/seeds. I did try this recipe with tofu, and it works just fine. In both cases, tofu and potatoes, just add the water gradually in step 3 while blending (not in step 1), otherwise your sauce will be too thin (since tofu and cooked potatoes have water in them already and cashews do not).
Chipotle powder is made from dried, smoked, jalapeño peppers, and as Google so aptly states, “They are then crushed into powder form, in pure, simplistic flavor glory.” I don’t eat fresh jalapeños (too hot for me) but I love chipotle powder; the key is not to use too much, which is why I went with ¼ teaspoon (use more or less if you wish; or for a very mild flavor, use “mild” chili powder).
Red onion: I used a yellow onion the first time I made this and the color was a bright, unnatural orange, so I opted for a red onion instead to get a more authentic cheesier color. But white, yellow or red can be used.
In the air-fryer: I also made this in my Breville Air Frier, and found the following settings to work well: set dial to "Roast" and preheat to 400F. Once the oven is up to temperature, place the baking pan with veggies on it on the "Roast" lower rack, and roast for 20 minutes. Toward the end, I like to keep an eye on it so as not to over-do it.
Nutritional yeast: Nutritional yeast is a dry, yellow, flakey condiment often used in vegan cheese sauces, since it has a somewhat cheesy flavor. I don’t use it though (and TrueNorth, where I teach, also does not) because most brands can be problematic health-wise. Most (1) are genetically modified; (2) contain either added or naturally occurring MSG (monosodium glutamate), which many people have physical reactions to; and (3) are fortified with “folic acid,” which is a synthetic form of vitamin B9, and is not as effectively utilized by the body as “folate,” the natural form of B9. Dietary folate—the form found in whole foods—is preferable to the synthetic folic acid found in supplements and processed foods. Having said all that, if you still want nutritional yeast, consider buying it from Well Your World. They make one that is non-fortified, non-GMO, non-irradiated, and non-ETO (ETO means that it hasn't been sterilized with ethylene oxide, a gas that kills fungus and bacteria. The gas is a carcinogen, but the EPA says that in tiny amounts it is safe—yikes!).

Roasted Red Pepper Sauce. The Best!!!!!!! A++
Cathy
Yay! 😉 Thanks Dave!
Paulette
Did you take off the peel from the roasted red pepper?
Cathy
No I didn't. But if you didn't want the dark parts, you could cut them out. I think they add flavor. 🙂
Valerie
I used this sauce for the Nachos recipe that you posted. Excellent!
There was some leftover from preparing the nachos, and I used it as a tasty salad dressing. I may prepare it in the future for the purpose of a salad dressing.
Cathy
Oh, great idea! 😉
Carol
Does this sauce do well with freezing?? Thanks
Cathy
Yes! 🙂
Brett Torrey Haynes
Thanks for the insights on nutritional yeast and a link to a better version. I don't eat much of it on my mostly raw-food WFPB diet, but it's good to know the facts.
Cathy
Sure! Thanks Brett! 🙂

Discovered this recipe and technique for roasting the peppers, garlic, and onion. Now using it in every way I can think of - hummus, mac & cheeze, and as a sauce on anything. Fabulous!
Cathy
Yay! 🙂 Thanks Karen!
