Why you’ll love this keto chicken alfredo

• Homemade sauce: just butter, cream, garlic, and parmesan.
• 30 minutes: weeknight-friendly.
• Keto and gluten-free: served over veggie noodles.

Ingredients you’ll need

Freshly grated parmesan melts smoothly; pre-grated can make the sauce grainy.

• 1.5 lbs chicken breasts, sliced
• Salt and pepper, to taste
• 2 tablespoons butter
• 4 cloves garlic, minced
• 1.5 cups heavy cream
• 1.5 cups grated parmesan
• 1/4 teaspoon nutmeg (optional)
• 4 medium zucchini, spiralized (or shirataki noodles)

How to make keto chicken alfredo (step by step)

1. Season the chicken with salt and pepper. Melt 1 tablespoon of butter in a skillet over medium-high heat and cook the chicken until golden and cooked through, then set aside.
2. In the same pan, melt the remaining butter and cook the garlic for 30 seconds.
3. Pour in the heavy cream and simmer gently for 2-3 minutes.
4. Stir in the parmesan and nutmeg until the sauce is smooth and thickened.
5. Add the zucchini noodles and chicken, toss for 1-2 minutes to warm through, and serve immediately.

Food safety: cook chicken to a safe minimum internal temperature of 165°F (74°C). An instant-read thermometer is the surest way to check — see the FoodSafety.gov chart.

Tips for the best results

• Do not boil the cream hard, or it can separate.
• Cook zucchini noodles briefly so they do not turn watery.
• Grate your own parmesan for the smoothest sauce.

Variations & substitutions

• Use shirataki noodles for near-zero carbs.
• Add spinach or mushrooms to the sauce.
• Swap chicken for shrimp.

Storage & make-ahead

Refrigerate for up to 3 days. Reheat gently; the sauce may thicken, so add a splash of cream. Best made fresh with the noodles.
