Key Ingredients and Simple Swaps

This dish is built around simple pantry and fridge staples, but the right choices make a big difference. Here's what you'll need to make it truly shine.

• Pasta - Short pasta like rotini or bowtie holds the pesto well and adds great texture. Cook until just al dente to keep it firm in the salad.
• Cooked Chicken - Grilled or roasted chicken breast is perfect. You can also use store-bought rotisserie chicken for convenience.
• Pesto - Use homemade or high-quality store-bought pesto for the freshest basil flavor. If it's too thick, thin it with olive oil.
• Cherry Tomatoes - They add bursts of sweetness and color. Halve them to distribute them evenly through the salad.
• Mozzarella - Mini mozzarella balls (bocconcini) bring creaminess. You can also cube a block of mozzarella or use crumbled feta for a salty twist.
• Baby Spinach - Fresh spinach adds a mild, leafy crunch and color. You could also swap it for arugula if you prefer a peppery bite.

Pesto Chicken Pasta Salad Preparation

Once the pasta's boiling, everything else comes together fast - cook the pasta until al dente (about 8-10 minutes depending on shape). This recipe is all about building flavor with a few good ingredients and letting them do the work.

• Cook the Pasta - Boil your pasta in salted water until al dente. Drain and rinse briefly under cool water to stop the cooking and chill the pasta slightly.
• Prep the Chicken & Veggies - Slice or cube the cooked chicken. Halve the cherry tomatoes and drain the mozzarella balls if using. Chop any greens you're adding.
• Make the Pesto Base - In a large bowl, mix the pesto with a drizzle of olive oil and a splash of lemon juice (about 1 teaspoon) to brighten the flavor, similar to how it's used in pesto potato salad ideas for sides.
• Toss It All Together - Add the pasta, chicken, tomatoes, mozzarella, and spinach into the bowl. Toss well until everything is coated evenly.
• Chill and Serve - For best flavor, chill for 15-30 minutes before serving to let the ingredients absorb the pesto.

Every forkful brings herby, tangy, creamy, and savory together in a fresh and balanced way. It's just as good the next day.

Serve it with easy sides for chicken pesto pasta to round out the meal.
