Ingredients Overview: A Better-For-You Pasta Night
For the Chicken:
-
Boneless Skinless Chicken Breasts: Lean protein that cooks quickly and pairs beautifully with Alfredo sauce. You can also use chicken thighs for a juicier cut.
-
Salt, Pepper, Garlic Powder: Simple but essential seasonings to boost flavor.
-
Olive Oil or Avocado Oil: For searing the chicken and keeping it moist.
For the Alfredo Sauce:
-
Heavy Cream: Delivers the signature richness of Alfredo without needing flour or thickeners.
-
Garlic (Fresh, Minced): Adds aromatic depth that balances the creaminess.
-
Parmesan Cheese (Freshly Grated): Adds savory umami and thickens the sauce naturally.
-
Butter: Starts the sauce with a rich base and helps carry the garlic flavor.
For the Zoodles:
-
Zucchini (Medium to Large): The star of the dish. Spiralized into noodles, they soak up sauce beautifully.
-
Salt: Draws out excess moisture from zucchini to prevent soggy results.
-
Olive Oil (optional): For a light sauté before mixing with sauce.
Step-by-Step Instructions: Light Pasta Perfection
1. Prepare the Zoodles
-
Spiralize 3–4 medium zucchinis using a spiralizer or buy pre-spiralized zucchini noodles.
-
Place them in a colander, sprinkle lightly with salt, and let them sit for 15–20 minutes to release excess water.
-
After draining, gently pat them dry with a paper towel.
Tip: This step helps prevent the dish from becoming watery and keeps the sauce creamy.
2. Cook the Chicken
-
Season both sides of 2 chicken breasts with salt, pepper, and garlic powder.
-
Heat 1 tablespoon olive oil in a large skillet over medium-high heat.
-
Sear the chicken 5–6 minutes per side, or until golden and fully cooked (internal temp 165°F).
-
Remove from skillet, let rest for a few minutes, then slice thinly.
3. Make the Alfredo Sauce
-
In the same skillet, reduce heat to medium. Melt 2 tablespoons of butter.
-
Add 3–4 cloves of minced garlic and sauté for 1 minute until fragrant.
-
Stir in 1 cup of heavy cream and let it simmer gently for 2–3 minutes.
-
Whisk in ¾ cup of freshly grated Parmesan cheese and a pinch of salt and black pepper.
-
Stir continuously until smooth and thickened, about 2 more minutes.
Optional Add-ins: A pinch of nutmeg or red pepper flakes for added depth.
4. Combine and Finish
-
Add the sliced chicken back into the skillet and toss to coat with Alfredo sauce.
-
Gently fold in the drained zucchini noodles and cook for just 1–2 minutes, enough to warm through without overcooking.
Note: Zucchini noodles release liquid quickly. Avoid overcooking to preserve texture.
5. Serve
-
Divide into bowls and top with extra Parmesan and fresh parsley.
-
Serve immediately for best texture.

Frequently Asked Questions (FAQs)
1. Do I need to cook the zucchini noodles first?
No, just a quick toss in the hot Alfredo sauce is enough. Overcooking makes them watery. Letting them rest with salt and drying them well ensures the best texture.
2. Can I use jarred Alfredo sauce?
Yes, but the flavor and texture won’t be as fresh or creamy. Homemade takes just a few extra minutes and is worth the effort.
3. How do I spiralize zucchini if I don’t have a spiralizer?
You can use a julienne peeler or slice thin strips with a knife. Some grocery stores also sell pre-spiralized zoodles in the produce or frozen section.
4. How long do leftovers last?
Store leftovers in an airtight container for up to 3 days in the fridge. Reheat gently on the stove or in the microwave. The zoodles may release more liquid, so reheat uncovered to evaporate excess moisture.
5. Can I freeze this dish?
Not recommended. Zucchini noodles become mushy when frozen and thawed. For best results, enjoy fresh or refrigerated.
6. Can I use other spiralized vegetables?
Yes! Try spiralized yellow squash, sweet potato (roast first), or even cabbage for a creative variation.
7. Is this dish keto-friendly?
Yes, this recipe is naturally low in carbs, high in fat and protein — making it ideal for keto diets. Just be sure to use high-fat dairy and no added flour.
