When takeout sounds tempting but you know you should cook, this five-ingredient pasta dish is the perfect solution to keep you out of the drive-thru. Simple, fast, and flavorful, it’s designed to get dinner on the table without a lot of fuss.
Instant Pot Pesto Chicken Pasta relies on only a handful of ingredients: pasta, pesto sauce, broth, leftover or cooked chicken, and Parmesan cheese. The combination is classic—pesto delivers bright, herbal flavor while the broth helps the pasta cook into a silky sauce that coats every bite. Adding cooked chicken turns it into a complete meal with protein, and finishing with grated Parmesan gives savory depth and a hint of creaminess.
One of the best things about this recipe is how little prep it requires. If you have leftover roasted or poached chicken, you can shred or cube it and add it toward the end of cooking to warm through. If you’re starting with raw chicken, you can cook it first in the Instant Pot or on the stovetop and then mix it in with the pasta and pesto. Either way, the process is straightforward and forgiving.
If you don’t own an Instant Pot, the dish is easy to make on the stovetop. Cook the pasta in a large pot of simmering broth (or broth diluted with water if you prefer a milder flavor) until al dente, then drain most of the liquid, leaving a little to loosen the sauce. Stir in the pesto, add the cooked chicken, and finish with grated Parmesan. The starch in the pasta helps bind the sauce, creating a creamy coating without needing cream or butter.
Variations are simple and adaptable to what you have on hand. For extra vegetables, stir in cherry tomatoes, spinach, peas, or roasted bell peppers near the end of cooking so they retain some texture. For a nuttier pesto flavor, add a small handful of toasted pine nuts or walnuts to the finished dish. If you like a touch of heat, a pinch of red pepper flakes or a drizzle of chili oil brightens the profile nicely.
To make this meal more family-friendly, use a mild, kid-pleasing pesto and small pasta shapes like rotini or penne that capture the sauce. For an adult-oriented twist, add a squeeze of lemon juice and some lemon zest to brighten the pesto, or mix in a spoonful of mascarpone or cream cheese for an extra-luxurious texture.
Storage and reheating are easy. Store leftovers in an airtight container in the refrigerator for up to three days. Reheat gently on the stovetop over low heat with a splash of broth or water to loosen the sauce, or microwave in short bursts, stirring between intervals. The pasta will absorb sauce as it sits, so a little extra liquid helps restore the original sauciness.
Helpful tips: use good-quality pesto—homemade or store-bought both work—and freshly grated Parmesan rather than pre-grated for the best flavor and texture. If you prefer a creamier sauce, stir in a small amount of cream, half-and-half, or ricotta. Taste before serving and adjust seasoning with salt and pepper as needed; pesto can vary in saltiness depending on the brand or recipe.
This five-ingredient pasta is a reliable weeknight go-to: economical, quick, and flexible. With minimal effort, you get a satisfying plateful of comfort and flavor that keeps you out of the drive-thru and close to home cooking.
