Pesto Tortellini Pasta Salad turns cheese tortellini, pesto, cherry tomatoes, mozzarella, and red onion into a crisp-edged pasta salad with a fresh, glossy finish. The air fryer gives the cooked tortellini lightly golden edges before everything gets tossed with pesto, so the salad has more texture than a standard chilled pasta bowl. I like this version for warm-weather lunches, potluck sides, and simple dinners when you want something colorful without a heavy sauce. The pesto coats the pasta while the tomatoes add juiciness, the mozzarella brings creamy bites, and the red onion gives a sharp little crunch. Serve it slightly warm, room temperature, or chilled after the tortellini has cooled completely. It is also a useful make-ahead side because the pesto keeps the pasta coated after chilling.

Why You’ll Love This Pesto Tortellini Pasta Salad

This pasta salad keeps the pesto-tomato-mozzarella combination familiar while adding a light air fryer texture. Here’s why:

• Crisp-edged tortellini: A short air fryer finish gives the cooked cheese tortellini golden spots and a firmer bite, which helps the salad feel more satisfying than a soft pasta-only version.
• Fresh pesto coating: The pesto clings to the warm tortellini and works like a built-in dressing, so every bite gets herbs, oil, garlic, and cheese without needing a separate vinaigrette.
• Good for sharing: Cherry tomatoes, mozzarella balls, and red onion make this salad colorful, sturdy, and easy to portion for cookouts, potlucks, lunch boxes, or a casual dinner spread.
• Flexible serving temperature: You can serve it warm right after tossing, let it sit at room temperature, or chill it for a firmer pasta salad texture later.
• Low-effort prep: The ingredients are short and familiar, and the air fryer step only needs a shake halfway through to keep the tortellini evenly crisped.

Ingredients You’ll Need

• Cheese tortellini (1 20 ounce bag): I use fresh or refrigerated cheese tortellini when possible because it cooks fast and air fries with a tender center. Cook it just until tender, then drain very well before crisping.
• Pesto (1 cup): Pesto acts as both the coating and dressing for this salad. A thicker basil pesto gives the tortellini better coverage, while a thinner pesto can be stirred again before tossing.
• Cherry tomatoes (1 and 1/2 cups, sliced in half): Halved cherry tomatoes add juicy freshness and help balance the rich pesto and cheese. Slice them evenly so they mix through the salad without releasing too much liquid.
• Marinated mozzarella balls (1 12 ounce container, drained): Drain the mozzarella well so the marinade does not water down the pesto coating. Smaller pearls can be used whole, while larger balls can be halved.
• Red onion (1/4 cup, diced): Red onion adds a crisp bite and sharp contrast to the creamy tortellini and mozzarella. Dice it small so the onion flavor stays balanced in each forkful.

Before You Start

• Cook the tortellini first: Follow the package directions and stop as soon as the pasta is tender so it does not split in the air fryer.
• Drain very well: Moisture is the biggest reason tortellini steams instead of crisping, so let it sit in the colander briefly.
• Preheat the basket: A 2-3 minute preheat helps the tortellini start crisping right away instead of sticking to a cool basket.
• Prep the salad mix-ins: Halve the tomatoes, drain the mozzarella, and dice the onion before the tortellini comes out hot.

How to Make Pesto Tortellini Pasta Salad

• Step 1 – Cook Tortellini: Cook the cheese tortellini according to the package directions until just tender, then drain it well. Let it sit for a few minutes so surface steam escapes and the pasta is not wet going into the basket.
• Step 2 – Coat Lightly: Place the cooked tortellini in a bowl and toss it with about half of the pesto. The pasta should look lightly coated, not heavy or oily, because too much pesto can smoke or collect under the basket.
• Step 3 – Air Fry: Preheat the air fryer to 380°F for 2-3 minutes. Arrange the tortellini in a single layer, working in batches if needed, and air fry for 7-9 minutes until the edges look lightly golden.
• Step 4 – Shake Halfway: Shake the basket halfway through cooking so the tortellini browns more evenly and does not stick in one spot. Start checking at 7 minutes if your tortellini pieces are small or thin.
• Step 5 – Toss Salad: Transfer the warm tortellini to a large bowl and gently fold in the remaining pesto, cherry tomatoes, drained mozzarella balls, and diced red onion. Serve warm, or cool before refrigerating for a chilled salad.

Best Air Fryer Settings

For the best texture, air fry this recipe at 380°F for about 7-9 minutes. Shake halfway through so the tortellini crisps at the edges without drying out.

• Temperature: 380°F is hot enough to crisp the pasta edges while keeping the cheese filling tender.
• Cook Time: Plan on 7-9 minutes for refrigerated tortellini, checking early if the pieces are smaller.
• Preheat: Preheat for 2-3 minutes so the pesto-coated tortellini starts crisping as soon as it hits the basket.
• Basket Tip: Keep the tortellini in a single layer, and cook in batches if your air fryer basket is small.

How to Get It Extra Crispy

• Drain very well: Let the cooked tortellini release steam before air frying so moisture does not soften the edges.
• Coat lightly: Use just enough pesto to cover the pasta before cooking, then add more after air frying.
• Do not overcrowd: Leave space around the tortellini so hot air can move across the pasta instead of trapping steam.
• Shake halfway: Tossing the basket halfway helps the curved edges crisp more evenly on both sides.
• Add extra minutes carefully: For a firmer bite, cook 1-2 minutes longer and check often so the cheese filling stays tender.

How to Know When Pesto Tortellini Pasta Salad Is Done

• Golden edges: The tortellini should have lightly browned edges and a few crisp spots, not a hard or dry shell.
• Tender center: The pasta should still feel tender inside, and the cheese filling should be warm before mixing with the salad ingredients.
• Pesto coating: After tossing, the pesto should coat the tortellini evenly without pooling heavily at the bottom of the bowl.
• Fresh mix-ins: Tomatoes should stay juicy, mozzarella should remain creamy, and the red onion should add a crisp bite.

Helpful Air Fryer Tips

• Use cooked tortellini: Dry tortellini from the package will not cook properly in the air fryer, so boil or cook it first.
• I check early: My air fryer browns pesto-coated pasta fast, so I start checking around 7 minutes.
• Work in batches: A crowded basket traps steam and can make the tortellini chewy instead of crisp around the edges.
• Use parchment carefully: Perforated parchment can help with cleanup, but only add it after preheating and once food weighs it down.
• I stir gently: Tortellini can tear if mixed too hard, so I fold in the tomatoes and mozzarella with a wide spoon.
• Adjust for frozen tortellini: Cook frozen tortellini according to the package first, drain well, then air fry the same way.

How to Store and Reheat

• Fridge: Store leftovers in an airtight container for up to 3 days, stirring before serving because pesto can settle.
• Freezer: Freezing is not ideal because tomatoes and mozzarella can turn watery after thawing.
• Serve chilled: For cold pasta salad, refrigerate until fully chilled, then loosen with a small spoonful of pesto if needed.
• Air fryer reheat: Reheat the tortellini portion at 350°F for 2-3 minutes, then add fresh tomatoes and mozzarella after warming.
• Microwave note: The microwave works for warmth, but it will soften the crisp edges from the air fryer.
• Food safety: Do not leave the salad at room temperature for more than 2 hours because it contains cheese.

Easy Swaps & Add-Ins

• Spinach tortellini: Use spinach and cheese tortellini for a greener pasta base that still works with basil pesto.
• Sun-dried tomatoes: Add chopped sun-dried tomatoes for a deeper, tangy flavor that pairs well with mozzarella.
• Baby spinach: Fold in a handful of baby spinach after air frying so it softens slightly from the warm pasta.
• Grilled chicken: Add cooked chicken pieces to make the salad more filling for lunch or dinner.
• Parmesan finish: Sprinkle grated Parmesan over the finished salad for a saltier, sharper cheese note.
• Balsamic drizzle: Add a small drizzle just before serving if you like a sweeter contrast with pesto and tomatoes.

What to Serve With Pesto Tortellini Pasta Salad

• Air fryer chicken tenders: The crisp chicken makes this pasta salad feel like a complete family-style meal.
• Grilled shrimp: Shrimp adds a light protein that pairs well with pesto, tomatoes, and mozzarella.
• Garlic bread: Toasted garlic bread is useful for scooping up extra pesto at the bottom of the bowl.
• Green salad: A simple leafy salad balances the cheese tortellini and keeps the plate fresh.
• Turkey sandwiches: Serve this as a pasta side with sandwiches for lunches, picnics, or casual dinners.
• Roasted vegetables: Zucchini, peppers, or broccoli add color and make the meal more vegetable-forward.
