Pesto Chicken Pasta — Quick Weeknight Dinner Recipe

Bright basil, toasty pine nuts, and juicy seared chicken come together in a sauce that smells like summer. Pesto chicken pasta fills the kitchen with warm herb aroma and delivers big flavor in under 40 minutes. I perfected this version after testing it eight times, adjusting salt and cooking times until the chicken stayed juicy and the sauce clung to every strand. The result is a balanced, creamy-feeling sauce without heavy cream and a method that works on busy weeknights.

Why This Recipe Works

Fresh basil and toasted pine nuts give a bright, nutty flavor that canned pesto can’t match. Toasting deepens the nut flavor.
Short-cooking chicken breasts sliced thinly stay juicy; cooking to 74°C (165°F) ensures safety without dryness.
Starchy pasta water binds the sauce to the pasta for a silky finish without extra oil or cream.
Finely grated Parmigiano-Reggiano melts into the sauce for savory depth and better texture than pre-grated cheese.
A quick pan-deglaze with lemon or white wine lifts browned bits for extra savory complexity.

Ingredients Breakdown

Basil pesto (makes about 200 g / 7 oz): Fresh basil leaves, 60 g (½ cup) toasted pine nuts, 60 g (½ cup) finely grated Parmigiano-Reggiano, 120 ml (½ cup) extra-virgin olive oil, 1 garlic clove, salt to taste. Role: the flavor base and emulsified sauce. Substitution: store-bought pesto works but skip extra oil to avoid greasiness.
Pasta: 400 g (14 oz) dried pasta such as fusilli, penne, or farfalle. Role: captures bits of sauce and chicken. Use high-quality semolina pasta for better texture.
Chicken: 600 g (1.3 lb) boneless, skinless chicken breasts, sliced into 1.5 cm (½-inch) strips. Role: protein and savory contrast. Tip: pound thicker parts to even thickness for even cooking.
Aromatics: 1 small shallot or ½ medium onion, minced (about 50 g / ½ cup). Role: sweet background flavor. Cook until translucent.
Lemon: 1 lemon, zested and juiced (about 2 tbsp / 30 ml). Role: brightness and to cut richness.
Pasta water: Reserve 240–480 ml (1–2 cups). Role: starchy binder to marry pesto and pasta.
Olive oil and butter: 1 tbsp (15 ml) olive oil for searing; optional 1 tbsp (15 g) unsalted butter for finishing for silkiness.
Salt & pepper: Adjust to taste. Use Diamond Crystal kosher salt if possible; if using Morton’s, halve the amount because it is denser.
Optional extras: halved cherry tomatoes (125 g / 1 cup) for acidity, 60 g (½ cup) baby spinach for color, or red pepper flakes for heat.

Substitutions with impact warnings:

Dairy-free: Use 60–80 g (¼–⅓ cup) nutritional yeast in place of Parmigiano-Reggiano. The result is less savory and not as creamy.
Nut-free: Replace pine nuts with 60 g (½ cup) toasted sunflower seeds; flavor will be flatter.
Protein swap: Use shrimp (about 450 g / 1 lb) but reduce cooking to 2–3 minutes per side; overcooking makes shrimp rubbery.

Essential Equipment

28–30 cm (11–12 inch) skillet: wide surface means fast, even searing. If you only have a smaller pan, cook chicken in batches.
Large pot (5–6 liters): for boiling pasta without crowding.
Microplane or fine grater: for zesting lemon and grating Parmigiano-Reggiano finely.
Food processor or blender: for pesto. If you don’t have one, finely chop basil and nuts and whisk in oil gradually.
Tongs and a slotted spoon: to move pasta and toss evenly.
Instant-read thermometer: ensures chicken reaches 74°C (165°F) without overcooking.
Optional: heatproof bowl to finish sauce and reserved pasta water.

If you don’t have a food processor, pulse basil and nuts in a blender or finely chop and whisk vigorously with oil.

Step-by-Step Instructions

Serves 4. Prep time 15 minutes, Cook time 20 minutes, Inactive time None, Total time 35 minutes.

Step 1: Make the pesto

Combine 80 g (3 cups) packed basil leaves, 60 g (½ cup) toasted pine nuts, 60 g (½ cup) grated Parmigiano-Reggiano, 1 garlic clove, and 120 ml (½ cup) olive oil in a food processor. Pulse until smooth but still slightly textured, about 30–45 seconds. Season with ½ tsp salt and taste; adjust with more lemon zest if needed.

Step 2: Boil the pasta

Bring 4 liters (16 cups) of salted water to a boil and add 400 g (14 oz) pasta. Cook to 1–2 minutes before package al dente (check at 6–8 minutes for typical shapes), about 8–10 minutes depending on pasta. Reserve 240–480 ml (1–2 cups) pasta water, then drain the pasta.

Step 3: Sear the chicken

Heat 1 tbsp (15 ml) olive oil in the skillet over medium-high until shimmering, about 2 minutes. Add the chicken strips in a single layer and cook until golden, 2–3 minutes per side, flipping once. Cook to an internal temperature of 74°C (165°F). Remove chicken and rest for 3 minutes.

Step 4: Sauté aromatics and deglaze

Reduce heat to medium, add 1 tbsp (15 g) butter or 1 tsp (5 ml) olive oil, then the minced shallot. Sauté until translucent and fragrant, about 3–4 minutes. Add 1–2 tbsp (15–30 ml) lemon juice or 60 ml (¼ cup) white wine and scrape browned bits, about 30 seconds.

Step 5: Combine pasta, pesto, and chicken

Add drained pasta to the skillet with aromatics, then stir in 120–240 ml (½–1 cup) reserved pasta water and 160 g (about 2/3 cup) pesto. Toss for 1–2 minutes until sauce coats the pasta and becomes silky. Return chicken and any rested juices to the pan and toss to warm through for 1 minute. Do not overcook — stop as soon as everything is glossy and combined.

Step 6: Finish and serve

Remove from heat, fold in 30 g (⅓ cup) grated Parmigiano-Reggiano and lemon zest. Taste and season with salt and pepper. Garnish with extra pine nuts, a drizzle of olive oil, and torn basil leaves. Serve immediately.

Expert Tips & Pro Techniques

Use room-temperature chicken for faster, more even searing. Cold chicken cools the pan and causes steaming.
Common mistake: over-saucing. If your pasta looks oily, you added too much pesto or oil. Fix: add more drained pasta or a splash of pasta water to emulsify.
Toast nuts in a dry skillet for 3–4 minutes, tossing frequently, until fragrant and slightly darker. Watch carefully; they burn fast.
Make-ahead: prepare pesto up to 2 days ahead and store airtight with a thin film of olive oil on top to prevent browning. Reheat gently or toss cold with warm pasta.
Professional trick for silky sauce: warm the pesto slightly before adding to pasta and use pasta water at about 70°C (160°F) to emulsify without cooking herbs.
One-pot adaptation: cook chicken, then sauté shallot and add uncooked pasta, broth, and pesto to finish in the pan for a simpler cleanup. For guidance, see a similar one-pot method linked later.

Storage & Reheating

Refrigerator: Store in an airtight container for 3–4 days. Keep sauce and pasta together; the pasta will soak up sauce but reheats well.
Freezer: Freezing cooked pesto chicken pasta changes texture; sauce may separate. Freeze only the pesto (up to 3 months) or cooked chicken separately (up to 2 months). To freeze pesto, spoon into ice cube tray and transfer cubes to a freezer bag.
Reheating: Reheat gently on the stove in a skillet over low heat with 1–2 tbsp (15–30 ml) water or olive oil to revive the sauce, about 3–5 minutes. Alternatively, reheat in a 175°C (350°F) oven for 8–10 minutes covered. Avoid microwaving if you want the best texture.

Variations & Substitutions

Creamy version: Stir in 120 ml (½ cup) heavy cream or crème fraîche at the end and reduce pasta water by half. The sauce becomes richer; add less cheese.
Gluten-free: Use 400 g (14 oz) GF pasta and follow the same cook time on the package. The sauce is the same; add ½ tsp xanthan gum if you want more cling.
Shrimp swap: Replace chicken with 450 g (1 lb) peeled shrimp. Sear 1–2 minutes per side until opaque. Add to pasta at the end and toss 30 seconds.
Veg-forward: Add 125 g (1 cup) halved cherry tomatoes and 60 g (2 cups) baby spinach during Step 5. Tomatoes soften in 2–3 minutes and spinach wilts quickly.
One-pot weeknight method: Cook sliced chicken first, set aside, then sauté shallot, add 400 g (14 oz) pasta and 750 ml (3 cups) low-sodium chicken broth, simmer until pasta is almost done, then stir in pesto and chicken. Cooking time increases by 2–4 minutes.

Serving Suggestions & Pairings

Light salad: A simple arugula salad with lemon vinaigrette cuts the richness.
Vegetable side: Roasted green beans or sautéed asparagus complement the basil notes.
Bread: Serve with garlic bread or crusty ciabatta to sop up sauce.
Wine: Pair with a chilled Vermentino or a crisp Sauvignon Blanc.
For a heartier meal, serve alongside a bacon-forward pasta for crowd-pleasing variety.

Frequently Asked Questions

Q: Why did my chicken turn out dry?
A: Most dry chicken comes from overcooking. Use an instant-read thermometer and remove chicken at 74°C (165°F). Rest for 3 minutes; carryover heat balances juices.

Q: Can I make this without garlic or nuts?
A: Yes. Omit garlic for a milder sauce and replace pine nuts with 60 g (½ cup) toasted sunflower seeds for a nut-free option. Flavor will differ slightly.

Q: Can I double this recipe?
A: Yes. Double ingredients and use two skillets or cook chicken in batches to avoid overcrowding the pan and steaming the meat.

Q: Can I prepare this the night before?
A: You can make the pesto and cook chicken a day ahead. Keep pesto chilled with a thin oil layer. Reheat chicken gently and toss with freshly cooked pasta for best texture.

Q: How long does this keep in the fridge?
A: Stored in an airtight container, it keeps 3–4 days. The pasta will absorb sauce over time; refresh with a splash of hot water or olive oil when reheating.

Q: Is fresh basil necessary?
A: Fresh basil gives the best flavor and color. Substituting with pre-made pesto is fine, but flavor and brightness may be reduced.

Q: What pasta shape works best?
A: Medium shapes that catch sauce, like fusilli, penne, or farfalle, work best. Thin strands like angel hair can be used but need gentler tossing.
