1-Step 1: Get everything ready firstBefore you start cooking, gather all your ingredients and tools. This makes the process smooth and helps this shrimp pesto pasta recipe move fast, which matters when you only have about 20 minutes. Set out a large pot for the pasta, a big skillet or pan for the shrimp, tongs, a strainer, and your cutting board for halving the cherry tomatoes. If you are using parsley, chop it now so the garnish is ready at the end. This little bit of prep keeps the whole meal stress-free.

2-Step 2: Boil the pastaBring a large pot of salted water to a boil. Add the 10 ounces of dry spaghetti, linguine, or fettuccine and cook according to the package directions until al dente. For most pasta shapes, that takes about 8 to 10 minutes. Make sure you stir once or twice while it cooks so the noodles do not stick together. If you want a silkier pesto pasta, save a splash of the pasta water before draining. That starchy water can help loosen the sauce later if needed.

3-Step 3: Season and cook the shrimpWhile the pasta cooks, heat 1 tablespoon of olive oil in a large pan over high heat. Add the peeled and deveined shrimp, then sprinkle them with 1 teaspoon Italian seasoning, salt, and pepper. Spread them out in a single layer so they cook evenly. Cook the shrimp for 2 to 4 minutes, turning once if needed, until they are pink and opaque. Do not overcook them. Shrimp go from perfect to rubbery fast, so take them off the heat as soon as they are done. If you prefer a more smoky flavor, you can also grill the shrimp instead of pan cooking them, which fits the pesto pasta and grilled shrimp stack idea nicely.

4-Step 4: Bring the pasta and pesto togetherDrain the pasta and add it directly to the pan with the shrimp. Turn off the heat first, then stir in the 3/4 cup basil pesto. Toss everything until the pasta is fully coated and the shrimp are mixed through. If the sauce looks thick, add a spoonful or two of reserved pasta water to help it cling to the noodles. This is a simple trick that makes the dish taste smoother and more restaurant-like without adding extra work.

5-Step 5: Add tomatoes and parmesanStir in the halved cherry tomatoes and the 1/4 cup parmesan cheese. The tomatoes add freshness and a little burst of sweetness, while the parmesan gives the shrimp pesto pasta a savory finish. Taste the dish and add more salt or pepper if needed. If you want a stronger pesto flavor, you can stir in a little more pesto at this point. Keep the heat low or off while you mix so the basil stays bright and fresh.

6-Step 6: Plate and garnishSpoon the pasta into bowls or onto plates, then top with the shrimp so they sit on the pasta like a stacked presentation. That simple finish makes the meal look more polished, even though it took very little time. Sprinkle chopped parsley over the top if you like, and serve right away. This quick grilled shrimp pesto pasta pairs well with garlic bread, a green salad, or simple roasted vegetables. For a heartier dinner, you can serve it next to grilled vegetables with a zesty marinade.
