Cook the pasta according to the package instructions; drain and set aside.
While the pasta is cooking, make the sauce: heat 1 tablespoon of olive oil in a skillet over medium heat, then add the garlic and shallot and sauté for 2-3 minutes; transfer to a blender.
Add the remaining olive oil, along with the roasted red peppers, cashews, milk, nutritional yeast, red pepper flakes, salt, and pepper to the blender and blend for 1 minute or until the sauce is smooth.
Pour the sauce over the cooked pasta, then garnish with fresh basil. Enjoy!
