There’s a moment—about two bites in—when the silky basil-cream sauce coats the tender chicken and perfectly al dente pasta—when dinner stops feeling like a weekday obligation and starts feeling like a tiny vacation to the Italian coast. I created this recipe after a whirlwind trip to Liguria where I tasted my first true trofie al pesto in a tiny trattoria overlooking the harbor. The owner’s nonna stirred a splash of cream into the pesto at the last second, swearing it “made the herbs sing.” She was right. That gentle swirl of cream softens the raw edge of the garlic, rounds out the saltiness of the Parmigiano, and turns a bright green sauce into something that literally melts on your tongue.

Back home, I spent months testing ratios, temperatures, and timing until I landed on this version: juicy strips of pan-seared chicken, cork-screw pasta that hugs every drop of sauce, and a glossy pesto cream that clings without weighing things down. It’s fast enough for a frantic Tuesday (25 minutes, start to finish) yet elegant enough for company. Bring a big bowl to the table, crack some fresh pepper over the top, and watch even the pickiest eater close their eyes in bliss.

Why This Recipe Works

One-Pot Wonder: The pasta finishes cooking right in the sauce, releasing starch that naturally thickens the cream—no floury roux needed.
Restaurant-Level Chicken: A quick brine of salted water (5 minutes!) seasons the meat through and keeps every slice juicy, even if you accidentally overcook by 30 seconds.
Double Hit of Basil: Store-bought pesto for convenience, plus a handful of fresh ribbons at the end for that just-picked brightness.
Controlled Creaminess: Half-and-half plus a touch of pasta water creates a velvety texture without the heaviness of all-heavy-cream versions.
Flexible Veggie Add-Ins: The sauce welcomes spinach, sun-dried tomatoes, or peas without becoming watery.
Freezer-Friendly: Make a double batch of the chicken-pesto base; freeze flat in zip bags for up to 2 months. Reheat gently with a splash of milk and dinner is done in 8 minutes.

Ingredients You'll Need

Great ingredients don’t have to be expensive—just intentional. Below is what I reach for again and again, plus the little swaps that save the day when the grocery store’s basil looks sad.

Fusilli or Rotini (12 oz): The twists trap pockets of pesto cream. Gluten-free? Jovial brown-rice spirals hold up beautifully. For low-carb nights, I swap in chickpea pasta—it adds nutty flavor and extra protein.
Boneless Skinless Chicken Breasts (1¼ lb): Look for plump, rosy pieces with no gray edges. thighs work too; they bring a touch more richness and forgive a longer simmer.
Prepared Basil Pesto (⅔ cup): I keep Kirkland’s refrigerated pesto in the fridge at all times—it’s bright, nutty, and doesn’t separate like shelf-stable jars. In a pinch, combine ½ cup jarred pesto with ¼ cup fresh parsley to wake it up.
Half-and-Half (1 cup): Not just for coffee! The 50-50 blend of milk and cream thickens without the risk of curdling. Dairy-free? Use full-fat canned coconut milk; the faint coconut disappears under the basil.
Parmigiano-Reggiano (¾ cup freshly grated): Buy a wedge and grate it yourself—pre-shredded cellulose-coated cheese refuses to melt smoothly. Save the rind for soup.
Garlic (3 cloves, smashed): Smashing releases allicin, the compound that gives garlic its savory punch. If your cloves have green sprouts, remove them; they turn bitter when heated.
Reserved Pasta Water (up to 1 cup, salted): Liquid gold. The starch transforms cream into velvet and helps the pesto emulsify instead of float in greasy droplets.
Fresh Baby Spinach (2 packed cups, optional): It wilts in seconds and mellows the richness. Swap in kale ribbons, zucchini half-moons, or even thawed frozen peas.
Extra-Virgin Olive Oil (2 Tbsp): A peppery Tuscan oil stands up to the cream; delicate Ligurian oil is better drizzled on raw apps.
Sea Salt & Freshly Cracked Black Pepper: Taste early, taste often. Kosher salt dissolves faster; flaky salt is lovely for finishing.

How to Make Creamy Pesto Chicken Pasta That Melts in Your Mouth

Brine the Chicken

Fill a medium bowl with 4 cups cold water and 2 Tbsp kosher salt. Stir to dissolve, add chicken breasts, and let sit 5–10 minutes while you prep the remaining ingredients. This quick brine seasons the meat and buys you forgiveness if the stove runs hot.

Cook the Pasta

Bring a large pot of salted water to a rolling boil. Add fusilli and cook 1 minute shy of package directions (about 9 minutes). Reserve 1½ cups starchy cooking water, then drain. Do not rinse—you want that tacky surface for sauce adherence.

Sear the Chicken

Remove breasts from brine, pat very dry (moisture = steam = no sear), and slice into ½-inch strips. Heat olive oil in a 12-inch skillet over medium-high until shimmering. Add chicken in a single layer; cook 2–3 minutes per side until golden. Transfer to a plate—don’t worry about doneness; it’ll finish in the sauce.

Build the Base

Lower heat to medium. In the same skillet, add smashed garlic; sauté 30 seconds until fragrant but not browned. Pour in ¾ cup of the reserved pasta water, scraping the brown bits—those caramelized specks are pure flavor.

Create the Creamy Emulsion

Stir in half-and-half and bring to a gentle simmer (tiny bubbles around the edge). Whisk in pesto until the color turns a uniform grassy green. The sauce will look thin—that’s perfect; pasta will thicken it.

Marry Pasta & Sauce

Add drained fusilli and seared chicken (plus any resting juices) to the skillet. Toss constantly for 2 minutes, adding splashes of pasta water until everything is cloaked in glossy cream. Taste; adjust salt and pepper.

Wilt in Greens

Fold in spinach (or peas, zucchini, etc.) and cook 30–60 seconds, just until vibrant. Overcooking muddies the color and flavor.

Finish with Cheese & Basil

Off the heat, shower with freshly grated Parmigiano and a small handful of thin basil ribbons. The residual heat melts the cheese into stretchy strands. Serve immediately in warm bowls; pass extra cheese and pepper at the table.

Expert Tips

Control the Heat

If the cream boils, the fat separates and you’ll get an oily slick. Keep it at a lazy simmer—tiny bubbles, not a rolling wave.

Starchy Water is Magic

If the sauce tightens on standing, loosen with a splash of hot pasta water instead of milk; the starch re-emulsifies everything.

Make-Ahead Chicken

Sear a double batch of chicken on Sunday night. Refrigerate up to 4 days or freeze up to 2 months; dinner drops to 12 minutes.

Slice Against the Grain

Cut chicken on a slight bias across the grain; the shorter protein fibers give you fork-tender bites every time.

Keep it Green

Add a squeeze of lemon off the heat; the acidity perks up flavors and preserves the emerald color.

Reheat Gently

Microwave at 60% power with a damp paper towel over the bowl; stir every 30 seconds to avoid hot spots and rubbery chicken.

Variations to Try

Shrimp & Lemon: Swap chicken for 1½ lb large shrimp; sauté 1 minute per side. Add 1 tsp lemon zest with the garlic.
Smoky Bacon Ranch: Render 4 slices of chopped bacon; use bacon fat instead of olive oil. Replace pesto with 2 Tbsp ranch seasoning and ½ cup grated sharp cheddar.
Veggie Power: Skip chicken; roast broccoli, bell peppers, and red onion at 425°F for 15 minutes, then fold into the creamy pesto.
Spicy Calabrian: Stir in 1 tsp Calabrian chili paste with the garlic; top with torn burrata for a cooling contrast.
Sun-Dried Tomato & Artichoke: Add ¼ cup chopped oil-packed sun-dried tomatoes and ½ cup quartered artichoke hearts with the pasta.

Storage Tips

Refrigerator: Cool leftovers completely, transfer to an airtight container, and refrigerate up to 4 days. The sauce will thicken; loosen with a splash of milk or broth when reheating.

Freezer: Freeze individual portions in zip-top bags for up to 2 months. Press out excess air to prevent ice crystals. Thaw overnight in the fridge, then reheat gently.

Make-Ahead Components: Brined and seared chicken keeps 4 days refrigerated. The pesto cream base (without pasta) can be made 3 days ahead; warm slowly and thin with pasta water before adding pasta.
