Creamy Lemon-Pesto Chicken Pasta

This Creamy Lemon-Pesto Chicken Pasta is the kind of weeknight dinner that feels like a warm, restaurant-style hug without the fuss. Bright lemon, savory pesto, and tender chicken come together in a silky sauce that clings to every strand of linguine. It’s simple enough for a busy evening yet impressive enough for company. The flavors are balanced — a little tang from the lemon, herbaceous depth from the basil pesto, and a comforting creaminess from a quick roux and milk. A chopped, seeded tomato adds a pop of color and freshness at the end.

Before you get started: the ingredient list is concise and pantry-friendly. The method walks through cooking the pasta, seasoning and cooking the chicken, building a butter-based sauce thickened with flour, and finishing everything together with lemon zest and pesto. Read through once, then follow the steps in order for the best results.

Ingredients

• ▢3 to 4 boneless skinless chicken breasts
• ▢1 cup bottled lemon pepper marinade
• ▢2 tsp dried basil
• ▢2 Tbsp unsalted butter
• ▢1 tsp minced garlic
• ▢2 Tbsp all-purpose flour
• ▢1 cup milk
• ▢1 tsp lemon zest
• ▢⅓ cup pesto
• ▢12-oz linguine pasta
• ▢1 tomato, chopped and seeded

Equipment

• Large pot for boiling pasta
• Large skillet or sauté pan with lid
• Tongs or spatula
• Measuring cups and spoons
• Knife and cutting board
• Zester or microplane

Make-Ahead and Notes

• If you want to save time, cook the pasta and chicken ahead. Reheat gently and toss with the sauce just before serving.
• For a lighter version, use lower-fat milk; the sauce will be slightly less rich but still delicious.
• If you prefer, swap linguine for spaghetti or fettuccine — just keep the 12-ounce amount and adjust boiling time to the package directions.

Step-by-Step Directions

Follow these clear, ordered steps to make this Creamy Lemon-Pesto Chicken Pasta. The directions maintain the original sequence and ingredient amounts while clarifying techniques and timing.

1. Marinate the chicken: Place 3 to 4 boneless skinless chicken breasts in a shallow dish or resealable bag. Pour 1 cup bottled lemon pepper marinade over the breasts, turning to coat evenly. Let the chicken marinate for at least 15 minutes at room temperature or up to 2 hours in the refrigerator. Remove chicken from the marinade and discard any excess marinade.
2. Cook the pasta: Bring a large pot of well-salted water to a rolling boil. Add 12-oz linguine pasta and cook according to package instructions until al dente. Reserve about 1 cup of the pasta cooking water before draining. Drain the linguine and set aside.
3. Season the chicken: Sprinkle both sides of the marinated chicken breasts with 2 tsp dried basil. The lemon pepper marinade will provide seasoning and moisture; the dried basil adds a complementary herb note.
4. Sear the chicken: Heat a large skillet over medium-high heat. Add a little neutral oil if your pan needs it to prevent sticking. Place the seasoned chicken breasts in the hot skillet and cook 4–6 minutes per side, depending on thickness, until each breast reaches an internal temperature of 165°F (74°C) and is golden brown. Transfer the cooked chicken to a plate and tent loosely with foil to rest for 5 minutes, then slice or chop into bite-sized pieces.
5. Start the sauce: In the same skillet, reduce the heat to medium and add 2 Tbsp unsalted butter. Once melted, add 1 tsp minced garlic and cook briefly, about 30 seconds, until fragrant but not browned.
6. Make a roux and thicken: Sprinkle 2 Tbsp all-purpose flour into the melted butter and garlic, stirring constantly to form a smooth paste. Cook the flour for about 1 minute to remove the raw taste but do not let it brown.
7. Add milk to create the sauce: Gradually pour in 1 cup milk while whisking to prevent lumps. Continue cooking and whisking until the mixture thickens into a smooth, creamy sauce, about 2–3 minutes. If the sauce becomes too thick, thin it with a splash of the reserved pasta water until you reach a silky consistency.
8. Layer in bright flavors: Stir 1 tsp lemon zest into the sauce to brighten it. Add ⅓ cup pesto and stir until fully incorporated and the sauce turns a gentle green hue. Taste and adjust — if you want more tang, add a small squeeze of fresh lemon juice (optional).
9. Combine pasta and chicken: Add the drained linguine to the skillet with the sauce. Toss gently to coat the pasta evenly. Add the sliced or chopped cooked chicken to the pan and fold everything together so each strand of linguine is married to the creamy lemon-pesto sauce. Use reserved pasta water one tablespoon at a time if needed to loosen the sauce and help it cling to the noodles.
10. Finish with fresh tomato: Remove the skillet from heat and gently stir in 1 chopped, seeded tomato. The tomato should be added at the end to maintain its fresh texture and mild acidity, which balances the richness of the sauce.
11. Serve: Divide the Creamy Lemon-Pesto Chicken Pasta among plates or bowls. If desired, top with a small extra dollop of pesto or a light drizzle of olive oil for sheen. Serve immediately while hot.

Tips for Best Results

• Let the chicken rest after cooking so the juices redistribute; this keeps the meat juicy when sliced.
• Reserve pasta water: the starchy liquid is your ally for loosening and emulsifying the sauce.
• Keep the garlic from burning by lowering the heat before you add it to melted butter — burnt garlic tastes bitter and throws off the whole dish.
• If you prefer more herb flavor, sprinkle extra dried basil or a little black pepper at the end to taste.
• For a creamier sauce, stir in an extra tablespoon of butter right before serving or add a splash more milk while whisking.

Serving Suggestions

This dish pairs perfectly with a crisp green salad dressed with a lemon vinaigrette or a simple arugula salad tossed with olive oil and lemon. Garlic bread or a warm crusty loaf is great for sopping up any remaining sauce. For a drink, a chilled white or a sparkling water with a lemon wedge complements the bright flavors.

Make It Your Own

The beauty of this recipe is how flexible it is. Swap the linguine for gluten-free pasta if needed, or stir in a handful of baby spinach when you add the pesto for extra color and nutrition. If you like heat, a pinch of red pepper flakes tossed in with the garlic gives a lively kick. You can also swap the chopped tomato for halved cherry tomatoes for a sweeter burst in every bite.

Why This Works

The recipe balances richness, acidity, and herbs. The lemon pepper marinade infuses the chicken with bright, savory flavor. A simple butter-and-flour roux using milk creates a quick, velvety base that’s gentle enough to let the pesto and lemon zest shine. Adding the tomato at the end keeps a fresh texture contrast against the silky pasta and tender chicken. All elements come together fast, so the dish feels fresh and homemade.
