Bring a large pot of salted water to a boil. Add the pasta and cook according to the package instructions until it's al dente. Before draining, save 1/4 cup of the pasta water and set it aside.
While the pasta is cooking, melt the vegan butter in a large pan over medium heat. Add the minced garlic, red chili flakes (or cayenne pepper), and Italian seasoning. Sauté for about 1-2 minutes until the garlic is fragrant but not browned.
Drain the cooked pasta and add it to the pan with the garlic and spices. Toss until the pasta is coated with the buttery, spicy mixture. Add the pasta water a little at a time, continuing to toss the pasta until a silky sauce forms.
Stir in the sliced black olives. Taste and add more salt if necessary.
Divide the pasta between four plates. Garnish with fresh parsley if desired. Enjoy your Vegan Butter Chili Pasta hot.
For added protein, you could add cooked chickpeas, lentils, or a plant-based protein of your choice. Enjoy!
