This 5 ingredient keto chicken Alfredo is creamy, rich, and filling. It comes together in under 15 minutes and uses simple ingredients to create a proper, comforting meal without any extra steps. Serve it with zucchini noodles, cauliflower rice, or zero noodles to soak up the sauce.
Season the chicken evenly on both sides with salt and black pepper.
Heat the avocado oil in a large sauté pan over medium-high heat. Add the chicken and cook for 3– 4 minutes per side, until golden and cooked through. Remove from the pan and set aside.
Reduce the heat to medium and add the butter to the same pan. Once melted, add the garlic and cook until lightly golden and fragrant.
Add the mushrooms, season lightly with salt and pepper, and cook for 3–4 minutes until they release their moisture and the liquid begins to reduce.
Pour in the heavy cream and stir to combine. Let the sauce simmer gently until slightly thickened.
Return the chicken to the pan and spoon the sauce over it. Turn off the heat and finish with the chopped parsley.
Serve hot with the creamy mushroom Alfredo sauce spooned over the chicken.
