GF DF Chicken Fettuccine Alfredo - Olivia Adriance

This is a classic dish reworked to fit a gluten-free, dairy-free lifestyle without sacrificing flavor or comfort.

Traditional Alfredo relies on heavy cream, butter, and cheese. In this dairy-free version, soaked cashews blended with unsweetened almond milk, nutritional yeast, lemon, and seasonings create a luscious, creamy sauce.

Gluten-free fettuccine and seared chicken add texture and protein, making this an ideal date-night dinner or a cozy weeknight treat.

How to Make Gluten-Free, Dairy-Free Chicken Fettuccine Alfredo

Heat 1 tablespoon olive oil in a large nonstick skillet over medium heat.

Add the diced onion and sauté 2–3 minutes, then add minced garlic and cook another 2–3 minutes until the onion is soft and the garlic is fragrant but not browned.

Remove the onion and garlic from the skillet, add another tablespoon of olive oil, then add the chicken in a single layer. Cook the chicken 3–4 minutes per side until cooked through. I use chicken breasts cut into bite-sized pieces.

While the chicken cooks, prepare the gluten-free fettuccine according to package directions.

Recipe Tip

Plan ahead to soak the cashews. Cover raw cashews with water and refrigerate overnight or for at least 6 hours. Drain and rinse before blending.

To make the sauce, combine soaked cashews, the cooked onion and garlic, lemon juice, almond milk, nutritional yeast, salt, and pepper in a blender. Blend until completely smooth. Taste and adjust salt, nutritional yeast, or almond milk to reach the desired flavor and consistency.

When the chicken is cooked, remove it from the skillet and reduce the heat to low. Add the creamy sauce and the drained pasta to the skillet, tossing gently to combine. Return the chicken to the pan and toss once more to coat everything in sauce.

Serve immediately topped with chopped fresh parsley. Enjoy!
