Prepare the Chicken: Season the chicken breasts with salt, pepper, and Italian seasoning. Heat 1 tablespoon of olive oil in a skillet over medium heat and cook the chicken for about 6-7 minutes on each side, or until fully cooked and golden brown. Once cooked, set aside to rest before slicing.
Cook the Pasta: In a large pot of boiling salted water, cook the gluten-free fettuccine according to package instructions. Reserve 1/2 cup of pasta water before draining the noodles, then set aside.
Make the Creamy Sauce: In a high-speed blender, combine the soaked cashews, vegetable broth, nutritional yeast, minced garlic, onion powder, and a pinch of salt and pepper. Blend until smooth and creamy. If the mixture is too thick, add a little of the reserved pasta water to reach the desired consistency.
Combine Pasta and Sauce: In the same pot used for pasta, return the drained fettuccine and pour the creamy cashew sauce over the noodles. Toss the pasta gently over low heat, allowing it to coat well. If the sauce is too thick, gradually add more reserved pasta water until you achieve a silky consistency.
Slice and Serve: Slice the cooked chicken breasts and place them on top of the creamy pasta. Garnish with fresh chopped parsley and lemon zest if desired.
Enjoy!: Serve warm and enjoy the creamy, dairy-free goodness.
Notes
Soak cashews for at least 4 hours for the best texture.
