  • blender



  • 1 Onion diced
  • 2 Bell peppers diced
  • 1 can Diced tomatoes

Sauce ingredients to blend

  • 2 cups Unsweetened coconut milk such as Silk brand unsweetened coconut beverage
  • 2 Roasted red peppers from a jar
  • 2 tbsp Tapioca starch or corn starch
  • 2 tbsp Flour
  • 1 tbsp Nutritional yeast
  • 1 tbsp White miso


  • 1 tsp Garlic powder
  • 1 tsp Dry minced onion or onion flakes
  • 1/2 tsp Basil
  • 1/2 tsp Oregano
  • 1/4 tsp Chipotle pepper or chili powder
  • 1/4 tsp Ground cumin


  • Dice onions (about 1cm pieces) and then sauté for about 5 minutes. Dice peppers (about 3 cm pieces) and add to the pan with the onions. Sauté for an additional 5 minutes. Add 1 can of diced tomatoes.
  • While the vegetables simmer, blend the sauce ingredients for about 20 seconds or until smooth.
  • Pour the sauce mixture over the vegetables, add spices, and stir. Simmer until the sauce thickens and serve over pasta.

Sauté diced onions for about 5 minutes. Add diced peppers and sauté for 5 more minutes. I usually add about 1 – 2 tsp of olive oil to the pan to stir fry the vegetables, but you can also sauté them without oil. For oil-free sautéing, it works well to use a bit of the liquid from the canned diced tomatoes to keep vegetables from sticking to the pan.

Add 1 can of diced tomatoes to the pan with the onions and bell peppers. While the vegetables simmer, blend coconut milk, roasted red peppers, tapioca starch, flour, nutritional yeast, and miso until smooth. Corn starch can be substituted for tapioca starch. Tapioca flour is the same as tapioca starch. Note that flour is optional, but I like to add some so the sauce is extra thick. I use unbleached wheat flour but any flour will do. You can use rice flour or gluten-free flour mix if you prefer.

After blending, pour this sauce into the vegetable mixture in the pan. Add spices and stir. Simmer until the sauce thickens, and then serve over pasta. 

Additional Additions

I like to add soy curls to the sauce or on top of the pasta for added flavour and texture. You can stir fry or air fry the soy curls. With this creamy red pepper sauce, I like to make soy curls covered with their own sauce made from vegan mayo, bbq sauce, red pepper hot sauce, maple syrup, and lime juice. First, I hydrate the soy curls in vegetable broth. Next, I coat them with corn starch and/or flour. I then fry them in a bit of oil until crispy. Finally, I toss them with sauce right before serving. I used to cook the soy curls more after adding sauce, but I have found that this can make them soggy, so now I add the sauce right before serving.
