Creamy Pesto Chicken & Zucchini – A Weeknight Skillet Favorite
This is the kind of weeknight recipe you make once and keep on repeat. Tender chicken, crisp-tender zucchini, and a silky pesto cream sauce come together in one pan with minimal fuss. It’s cozy without being heavy, fresh without being fussy, and ready fast enough for a busy evening.
Serve it over pasta, spoon it on rice, or keep it low-carb and eat it as is. However you plate it, the flavors are bright, herby, and deeply satisfying.
Ingredients
Method
- Prep the ingredients. Pat the chicken dry and season with salt and pepper. Slice the zucchini into half-moons. Mince the garlic and chop the onion or shallot if using. Grate the Parmesan.
- Heat the pan. Set a large skillet over medium-high heat and add 1 tablespoon olive oil. When it shimmers, add the chicken in a single layer.
- Brown the chicken. Cook without moving for 2–3 minutes, then stir and cook another 3–4 minutes until the chicken is golden and mostly cooked through. Transfer to a plate and tent loosely with foil.
- Sauté aromatics. If the pan is dry, add a drizzle of oil. Lower heat to medium. Add onion/shallot and cook 2–3 minutes until softened. Stir in garlic and cook 30 seconds until fragrant.
- Cook the zucchini. Add zucchini and a pinch of salt. Sauté 3–4 minutes, stirring occasionally, until crisp-tender and lightly browned at the edges. Don’t overcook; it should still have a little bite.
- Build the sauce. Pour in the chicken broth, scraping up any browned bits. Stir in the pesto and bring to a gentle simmer.
- Make it creamy. Lower the heat and add the cream. Stir until the sauce looks smooth and slightly thickened, 1–2 minutes. If it gets too thick, add a splash more broth.
- Return the chicken. Add the chicken and any juices back to the pan. Simmer on low for 2–3 minutes to finish cooking. Taste and adjust salt, pepper, and add red pepper flakes if you like heat.
- Add brightness. Stir in the Parmesan until melted. Finish with a gentle squeeze of lemon to lift the flavors. Start small; you can always add more.
- Serve. Top with extra Parmesan and fresh basil. Serve over pasta, rice, cauliflower rice, or with crusty bread to swipe up the sauce.
Why This Recipe Works
Classic pesto brings a punch of basil, garlic, Parmesan, and olive oil, which instantly transforms simple chicken and zucchini into something special. Adding a splash of cream or half-and-half mellows the pesto and creates a velvety sauce that clings to every bite.
Cooking the zucchini just until crisp-tender keeps it from turning mushy and adds a welcome contrast to the saucy chicken. A quick sear on the chicken locks in juices, so the meat stays moist and flavorful rather than dry. Best of all, it’s a one-pan recipe with easy steps and easy cleanup.
What You’ll Need
- Chicken: 1.5 pounds boneless, skinless chicken breasts or thighs, cut into bite-size pieces
- Zucchini: 2 medium zucchini, halved lengthwise and sliced into half-moons
- Pesto: 1/3 to 1/2 cup good-quality basil pesto (store-bought or homemade)
- Cream: 1/2 cup heavy cream or half-and-half (for a lighter sauce)
- Broth: 1/3 cup chicken broth to loosen the sauce
- Garlic: 2 cloves, minced (optional if your pesto is very garlicky)
- Onion or Shallot: 1/2 small onion or 1 shallot, finely chopped (optional but adds sweetness)
- Olive Oil: 1–2 tablespoons
- Parmesan: 1/4 cup freshly grated, plus more for serving
- Lemon: 1/2 lemon for a squeeze of brightness
- Salt and Pepper: To taste
- Red Pepper Flakes: A pinch for gentle heat (optional)
- Fresh Basil: A few leaves for garnish (optional)

How to Store
Let leftovers cool until just warm, then transfer to an airtight container.
Refrigerate for up to 3–4 days. Reheat gently on the stove over low heat, adding a splash of broth or cream to loosen the sauce. Avoid boiling after reheating, as that can cause the sauce to separate.
This dish also freezes reasonably well for up to 2 months, though the zucchini will soften more after thawing. Reheat from thawed for best texture.
Benefits of This Recipe
- Fast and Flexible: From prep to plate in about 30 minutes, and easy to adapt to what you have.
- Balanced: Protein-rich chicken, lots of veggies, and a moderate amount of creamy sauce feel satisfying without being heavy.
- Meal-Prep Friendly: Holds up well for a few days and reheats nicely.
- One-Pan Cleanup: Fewer dishes means less stress after dinner.
- Kid-Approved Flavors: Creamy, cheesy, and herby—familiar yet special.
What Not to Do
- Don’t crowd the pan. Overcrowding steams the chicken and zucchini instead of searing them. Cook in batches if needed.
- Don’t overcook the zucchini. Soft zucchini will make the dish feel soggy.
Aim for crisp-tender.
- Don’t skip seasoning. Taste at the end and adjust salt, pepper, and lemon. Pesto varies in saltiness.
- Don’t boil the cream. High heat can cause the sauce to split. Keep it at a gentle simmer.
- Don’t add Parmesan too early. Stir it in at the end so it melts smoothly and doesn’t clump.
Alternatives
- Protein Swaps: Use turkey cutlets, shrimp (cook separately and add at the end), or a can of chickpeas for a meatless option.
- Dairy-Light: Swap heavy cream for half-and-half or whole milk plus 1 teaspoon cornstarch whisked in to help thicken.
- Veggie Variations: Add cherry tomatoes, spinach, or asparagus.
Keep total veggies to what fits in your pan without crowding.
- Pasta Night: Toss with cooked short pasta and a splash of pasta water to help the sauce cling.
- Gluten-Free: Serve over rice, polenta, or gluten-free pasta.
- Nut-Free Pesto: Choose or make a nut-free pesto if needed (use seeds like pumpkin or omit nuts entirely).
- Lemon-Basil Twist: Add extra lemon zest and a few torn basil leaves at the end for brighter flavor.
FAQ
Can I use rotisserie chicken?
Yes. Shred or cube about 3 cups of cooked chicken. Start at the sauce step, warm the zucchini and sauce, then stir in the chicken just to heat through.
You may need a little extra broth.
What kind of pesto is best?
Use a pesto you enjoy straight from the jar. Refrigerated pesto often tastes fresher than shelf-stable, but either works. Homemade is great if you have it.
Taste for salt, as brands vary.
Can I make it without cream?
Absolutely. Use more broth and add 2–3 tablespoons of mascarpone, cream cheese, or a splash of coconut milk for body. Or keep it brothy and bright with extra lemon.
How do I prevent the sauce from splitting?
Keep the heat low after adding cream, and avoid rapid boiling.
Add the Parmesan off heat or at a gentle simmer, and stir constantly. If it looks too thick, thin with warm broth.
What should I serve with it?
Pasta, rice, or crusty bread are classics. For lighter options, try zucchini noodles, spaghetti squash, or a simple green salad with lemon vinaigrette.
Can I add mushrooms or other vegetables?
Yes.
Sauté mushrooms first so they brown and release moisture, then proceed with onion and zucchini. Keep total volume reasonable so the pan can sear, not steam.
Is this recipe spicy?
Not by default. Add red pepper flakes to the sauce or serve them at the table.
Start with a pinch and build to taste.
How do I make it extra saucy?
Increase pesto to 1/2 cup, cream to 3/4 cup, and broth to 1/2 cup. Taste and balance with lemon and salt at the end.
Can I cook the chicken as whole cutlets?
Yes, but the cook time increases. Sear cutlets 4–6 minutes per side, remove, make the sauce, then return the chicken to finish.
Slice before serving for easy eating.
