Zucchini Noodle Chicken Alfredo: A Low-Carb Twist on Classic Comfort

I first made Zucchini Noodle Chicken Alfredo on a busy weeknight when I wanted something creamy and satisfying without the carb-heavy guilt. This dish transforms the traditional Italian classic into a lighter, keto-friendly version. The spiralized zucchini noodles soak up that rich, garlicky Parmesan sauce beautifully, while tender chicken breast adds protein and heartiness.

There’s something magical about twirling those vibrant green zucchini noodles in creamy Alfredo sauce. I love how this recipe delivers all the comfort of pasta Alfredo but keeps things fresh and nutritious. The key is getting the zucchini just right – tender but still with a slight bite, never soggy or watery. When I serve this low-carb chicken Alfredo to my family, they don’t even miss the traditional pasta. The combination of buttery garlic sauce, nutty Parmesan, and perfectly seasoned chicken creates a restaurant-quality meal right in your own kitchen.

What You’ll Need for This Low-Carb Alfredo

I always recommend using freshly grated Parmesan cheese instead of the pre-shredded kind for the smoothest, most flavorful sauce. The difference is truly noticeable in this Zucchini Noodle Chicken Alfredo.

• 3 medium zucchinis, ends trimmed and spiralized
• 2 boneless, skinless chicken breasts (about 12 oz)
• Salt and pepper to taste
• 2 tablespoons butter (I prefer unsalted so I can control the salt level)
• 3 cloves garlic, minced
• 1 cup heavy cream (room temperature works best)
• 1 cup grated Parmesan cheese (freshly grated recommended)
• 1/4 teaspoon nutmeg
• Fresh parsley for garnish
• 2 tablespoons olive oil

Pro tip: If you don’t have a spiralizer, you can use a julienne peeler or even buy pre-spiralized zucchini noodles from the store to save time.

How I Make This Creamy Zucchini Alfredo

I recommend preparing all your ingredients before you start cooking since this recipe moves quickly once you begin. Having everything ready makes the process smooth and stress-free.

Step 1: Prep the Zucchini Noodles Spiralize your zucchinis into noodles and place them in a colander. Sprinkle generously with salt and let them sit for 10 minutes (you can start prepping other ingredients during this time). This crucial step draws out excess moisture that would otherwise make your Zucchini Noodle Chicken Alfredo watery. After 10 minutes, pat the noodles completely dry with paper towels. Don’t skip this – wet zucchini will dilute your beautiful Alfredo sauce.

Step 2: Cook the Chicken to Perfection Season both sides of the chicken breasts with salt and pepper. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat until it shimmers. Add the chicken and cook for 6-7 minutes per side until the internal temperature reaches 165°F and the outside is golden brown. Remove from the skillet, let it rest for 5 minutes, then slice against the grain. The resting time keeps the chicken juicy.

Step 3: Create the Alfredo Sauce In the same skillet (don’t wash it – those browned bits add flavor), melt the butter over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant but not browned. Pour in the heavy cream and bring it to a gentle simmer, stirring occasionally. Watch for small bubbles around the edges.

Step 4: Add the Cheese Reduce the heat to low and gradually whisk in the Parmesan cheese, a handful at a time. This prevents clumping and creates a silky smooth sauce. Add the nutmeg and season with salt and pepper to taste. The sauce should be thick enough to coat the back of a spoon. If it’s too thick, add a splash of cream.

Step 5: Sauté the Zucchini Noodles Heat the remaining tablespoon of olive oil in a separate large skillet over medium-high heat. Add the dried zucchini noodles and sauté for just 2-3 minutes, tossing frequently. They should be tender but still have a slight crunch. Overcooking makes them mushy and releases more water.

Step 6: Bring It All Together Remove the Alfredo sauce from heat. Add the zucchini noodles to the sauce and toss gently to coat every strand. Top with the sliced chicken, garnish with fresh parsley and extra Parmesan if desired. Serve immediately while the sauce is creamy and the zucchini is at the perfect texture.

Perfect Pairings for Your Zucchini Alfredo

This creamy chicken Alfredo pairs beautifully with light, complementary sides that balance the richness.

Caesar Salad: The crisp romaine and tangy dressing cut through the creaminess of the Zucchini Noodle Chicken Alfredo, adding freshness and crunch to your meal.

Roasted Cherry Tomatoes: These add a pop of sweetness and acidity that brightens the rich sauce. Just toss them with olive oil, salt, and roast at 400°F for 15 minutes.

Steamed Broccoli: For extra vegetables and nutrients, steamed broccoli florets complement the low-carb theme while adding color and fiber to your plate.

Keeping Your Leftovers Fresh

This Zucchini Noodle Chicken Alfredo is truly best enjoyed immediately after cooking, but I understand that leftovers happen. Store any extras in an airtight container in the refrigerator for up to 1 day. The zucchini will release water as it sits, so expect a thinner consistency.

To reheat, I recommend using a skillet over medium-low heat rather than the microwave. Drain any excess liquid that has accumulated, then gently warm the dish, stirring frequently. You may need to add a splash of cream to revive the sauce. The texture won’t be quite as perfect as fresh, but it’s still tasty.

I don’t recommend freezing this dish. The zucchini noodles become very watery and mushy after thawing, and the cream sauce can separate. For best results with this low-carb chicken Alfredo, make only what you’ll eat in one sitting.
