This easy vegan roasted red pepper pasta sauce recipe is incredibly creamy, healthy, delicious and makes the perfect satisfying weeknight dinner! It’s a simple 10-ingredient recipe that is dairy-free and easy to make for everyone!
Peel the onion and garlic cloves. Cut the peeled onion in quarters but leave the garlic cloves whole. Cut the peppers in half and remove the seeds. Rinse and drain the peppers, then cut into strips.
Arrange the prepared vegetables (peppers, onions, and garlic) on a baking sheet and drizzle with a little oil. Roast in the oven for about 20 minutes, or until the skin blackens.
Meanwhile, in a large pot of salted water cook the pasta according to the package instructions until al dente. Then drain the cooking water and toss with a little olive oil to prevent the pasta from sticking as needed.
Place the roasted vegetables along with the non-dairy milk, cashew butter, tomato paste, nutritional yeast flakes, salt and a pinch of pepper or chili in a blender and blend until smooth and creamy (or use an immersion stick blender to purée the veggies).
Transfer the red pepper sauce into a skillet or saucepan and bring to the boil. Simmer until the sauce is thickened to desired consistency. Taste and adjust seasonings or add more non-dairy milk to thin as needed.
Add the cooked pasta to the sauce and toss to coat. Garnish with fresh parsley and roasted peanuts as desired. Enjoy!
Pasta: You can use your favorite (gluten-free) pasta variety. Also, sweet potato noodles, veggie noodles or spaghetti squash noodles are great!
Non-dairy milk: Use your favorite unsweetened non-dairy milk, such as almond, cashew, oat, rice, soy or coconut milk.
Cashew butter: Feel free to use another nut butter such as white almond butter or tahini (for nut-free option). Just take note that this may change the taste. You can also use 1/3 cup whole cashews. I suggest soaking them in boiling water for 20 minutes before blending.
Roasting veggies on the stove: You can also roast the veggies on the stove or substitute jarred roasted peppers to speed things up. Please read my blog post for details.
