Zucchini & Chicken Alfredo is a lighter, fresher take on the classic Italian-American pasta dish. Tender chicken thighs and delicate zucchini rounds are tossed with rigatoni in a creamy Parmesan sauce brightened with fresh lemon. It’s rich and satisfying without being heavy, with the perfect balance of indulgent creaminess and fresh vegetable flavor. This is comfort food that doesn’t weigh you down, and it’s so gosh darn good!

This recipe has become one of my weeknight favorites because it feels special but comes together in about 30 minutes. The lemon zest and juice cut through the richness of the cream sauce in the best way, and the zucchini adds color and nutrition without making it feel like a “healthy” compromise. I love using chicken thighs instead of breasts because they stay so tender and juicy. Whether I’m cooking for family or friends, this dish always gets compliments and clean plates.
Ingredients
- Dry rigatoni – I like rigatoni for its ridges that catch every bit of sauce, but penne or rotini work just as well.
- Olive oil
- Chicken thighs – I prefer thighs because they stay tender and juicy even after reheating. Slice them evenly so they cook quickly and brown nicely.
- Salt
- Garlic – Always use fresh garlic. It gives a punchy, aromatic flavor you’ll never get from the jarred kind.
- Green zucchini – I like using smaller zucchini because they’re more tender and less watery. Slice them thin for quick cooking with just a little bite left.
- Lemon zest – Zest your lemon before juicing. It’s easier that way and the zest brightens up the whole dish.
- Lemon juice – Start with two tablespoons, then taste and add more if you want a bolder lemon flavor.
- Parmesan cheese – Freshly grated is worth it. It melts beautifully and gives the sauce that restaurant-style flavor.
- Heavy whipping cream – Go for full-fat cream. It makes the sauce silky and rich without curdling.
- Fresh parsley
- Ground black pepper
How to Make Zucchini & Chicken Alfredo

Bring a large pot of salted water to a boil. Add the rigatoni and cook according to the package directions until al dente. Before draining, use a measuring cup or ladle to scoop out and reserve ½ cup of the starchy pasta cooking water; this will help adjust the sauce consistency later. Drain the pasta in a colander and set aside.
While the pasta cooks, prepare your chicken by slicing it into ½-inch strips with a sharp knife on a cutting board. If you haven’t already, mince your garlic; a garlic press makes this quick and easy if you have one. Use a sharp knife or a mandoline slicer to cut the zucchini into thin, even rounds. The mandoline creates perfectly uniform slices that cook at the same rate.
Heat the olive oil in a large skillet or sauté pan over medium heat. Add the sliced chicken thighs to the skillet and sprinkle with salt. Cook, stirring occasionally with a wooden spoon or spatula, for 3 to 4 minutes until the chicken is lightly browned on all sides and cooked through.
Add the minced garlic and sliced zucchini to the skillet with the chicken. Use your spatula to stir and sauté for about 2 minutes, just until the zucchini begins to soften but still has a slight bite. Transfer the chicken and zucchini mixture to a bowl and set aside.
Return the skillet to the heat and pour in the lemon juice. Use a wooden spoon to scrape up any browned bits stuck to the bottom of the pan; this adds tons of flavor to your sauce. Let the lemon juice simmer and reduce for 1 to 2 minutes until it concentrates slightly.
Pour the heavy cream into the skillet and stir in the grated Parmesan cheese, chopped parsley, and black pepper using a whisk or wooden spoon. Cook, stirring frequently, for 3 to 4 minutes. The sauce will begin to thicken as the cheese melts and combines with the cream. A silicone spatula works well for scraping the sides and ensuring nothing sticks.
Return the cooked rigatoni, chicken, and zucchini to the skillet with the sauce. Use tongs or a large spoon to toss everything together until the pasta and vegetables are well coated with the creamy sauce. If the sauce seems too thick, add a splash of the reserved pasta water and stir to loosen it to your desired consistency.
Remove from heat and use a microplane grater or zester to grate the lemon zest directly over the pasta. Toss once more to distribute the zest throughout.
Serve immediately in pasta bowls, garnished with extra chopped parsley, freshly grated Parmesan, or additional black pepper if desired.
Serving Suggestions
This Zucchini & Chicken Alfredo is a complete meal on its own, but you can serve it alongside a crisp green salad and crusty garlic bread for a fuller dinner. A glass of white wine like Pinot Grigio or Chardonnay pairs beautifully with the creamy sauce. For extra richness, top each serving with a few red pepper flakes or a drizzle of good-quality olive oil.
Storage Tips
Store leftover Zucchini & Chicken Alfredo in an airtight container in the refrigerator for up to 3 days. The sauce may thicken as it sits, so when reheating, add a splash of milk, cream, or chicken broth to loosen it. Reheat gently in a skillet over medium-low heat, stirring frequently, or microwave in 1-minute intervals, stirring between each. The zucchini will soften further upon reheating, but the dish still tastes delicious.
