This Spaghetti Pasta Salad is the cold pasta side dish I make on repeat all summer long. Tender spaghetti noodles get tossed with crunchy veggies, salty pepperoni, and a zippy homemade Italian dressing. It comes together in under thirty minutes of hands-on work, and it only gets better the longer it sits in the fridge. Perfect for potlucks, cookouts, and family dinners, this easy pasta salad is always a crowd-pleaser.

Instructions
Cook spaghetti in salted boiling water until al dente. Drain and rinse immediately under cold water until fully cooled.
Wash and dry vegetables thoroughly. Halve cherry tomatoes, dice cucumber and bell peppers, thinly slice red onion, and slice black olives.
Slice or quarter pepperoni, grate Parmesan cheese, and chop fresh parsley.
In a small jar or bowl, combine olive oil, red wine vinegar, garlic, Italian seasoning, Dijon mustard, and sugar. Season with salt and pepper. Whisk or shake until combined and slightly thickened.
Add cooled spaghetti to a large mixing bowl with tomatoes, cucumber, bell peppers, red onion, olives, and pepperoni. Pour about three-quarters of the dressing over top and toss gently to coat all noodles.
Cover and refrigerate for at least 2 hours. Before serving, toss again, add remaining dressing if needed, and top with Parmesan and parsley.
Notes
Make ahead: This salad is actually better when made a day ahead. The flavors meld and deepen overnight.
Dressing tip: Reserve some dressing to add just before serving, as noodles absorb dressing as they sit.
Pasta texture: Rinse pasta thoroughly with cold water to stop cooking and remove excess starch that causes clumping.
Vegetable prep: Pat vegetables dry after washing to prevent watering down the dressing.
Bottled dressing shortcut: Use 1 cup of good quality bottled Italian dressing instead of homemade if pressed for time.
Storage: Store in an airtight container in the refrigerator for up to 4 days. Toss before serving leftovers.
Add protein: Boost with grilled chicken, salami, or cubed mozzarella for a heartier main dish salad.
Spicy version: Add pepperoncini or a pinch of crushed red pepper flakes for heat.
Greek twist: Swap Parmesan for feta cheese and use kalamata olives instead of black olives.
Freezing not recommended: Vegetables lose their crunch and become watery when thawed.
