Ingredients (Serves 8–10 as a side)

16 oz (1 lb) pasta (rotini, farfalle, penne, or fusilli work best—shapes that hold pesto well)
2 cups prepared basil pesto (store-bought or homemade; use your favorite quality brand)
1½ cups cherry or grape tomatoes, halved (about 1 pint; choose ripe, sweet ones)
1 cup small fresh mozzarella balls (bocconcini or ciliegine; drained if packed in water)

Optional add-ins for extra flair: A squeeze of lemon juice, fresh basil leaves, pine nuts, or a pinch of red pepper flakes. Keep it to four ingredients for the core recipe.

Step-by-Step Instructions

Cook the pasta: Bring a large pot of salted water to a boil. Add the pasta and cook according to package directions until al dente (usually 8–10 minutes). Avoid overcooking- firm pasta holds up better in the salad.
Drain and cool: Drain the pasta in a colander and rinse briefly under cold water to stop the cooking and remove excess starch. This keeps it from getting sticky and helps the pesto coat evenly. Let it cool slightly (about 5–10 minutes) so the mozzarella doesn’t melt too much.
Combine everything: In a large mixing bowl, add the cooled pasta. Pour in the 2 cups of basil pesto and toss until every noodle is coated. The pesto should cling nicely without needing extra oil.
Add the fresh elements: Gently fold in the halved cherry tomatoes and fresh mozzarella balls. Be careful not to break the cheese too much- you want nice creamy bites!
Taste and adjust: Give it a quick taste. Add a pinch of salt, black pepper, or a splash of olive oil if it feels dry (pesto brands vary in thickness). If you like it brighter, squeeze in fresh lemon juice.
Chill and serve: Cover and refrigerate for at least 30 minutes (or up to overnight) to let the flavors meld. Serve cold or at room temperature. Garnish with extra basil or a few whole tomatoes for presentation, if you’d like!

Pro Tips for the Best 4 Ingredient Pasta Salad

Pasta choice – Short shapes like rotini or bowtie trap pesto in the crevices. Whole wheat or chickpea pasta adds protein and nutrition.
Pesto quality – Use a good refrigerated or jarred pesto (avoid shelf-stable if possible). Homemade is even better if you have extra basil.
Cheese tip – If mozzarella balls are large, cut them in half. For extra creaminess, use burrata torn into pieces.
Tomato swap – Grape tomatoes are sweeter and less watery than cherry; halve them for even distribution.
Make it ahead – This salad improves after chilling 4-24 hours. Store in an airtight container in the fridge for up to 3 days.
Serving ideas – Pair with grilled chicken, shrimp skewers, or Italian sausage for a main dish. It’s also great alongside burgers or sandwiches.
Storage – Leftovers keep well, but add fresh tomatoes or cheese if it dries out. A small dash of olive oil before tossing helps, too!
