Serve it straight from the fridge or let it sit at room temperature for a few minutes to soften. Here’s how to make it.

Ingredients for Pasta Salad Recipe Olive Garden Dressing

Short list. Big flavor. Everything you need for that Olive Garden vibe at home.

The pasta shape matters here—rotini or fusilli grabs the dressing best. Barilla or De Cecco hold up well in salads without turning mushy. For the veggies, organic cherry tomatoes (the good kind, not the watery ones) and English cucumbers (less seeds, more crunch) are worth the extra dollar. The olives? Grab a can of Lindsay black olives at any grocery store.

No rotini? Penne or farfalle work too—just avoid long strands like spaghetti. Out of pepperoncini? Banana peppers at half the amount are a solid swap. Want more cheese? Romanos or Asiago add a sharper kick. The dressing can be made with Greek yogurt instead of mayo for a lighter version (trust me on the full-fat version though).

This keeps 4-5 days in the fridge—actually gets better as it sits. Store in an airtight container (don’t skip this part). Perfect for making ahead, but add the Parmesan right before serving so it doesn’t clump.

Step-by-Step Instructions for Olive Garden Pasta Salad

Here’s how to nail this copycat dish with that signature Italian freshness everyone loves.

Step 1: Cook and Cool the Rotini Pasta

Boil the 1 lb Rotini Pasta in salted water according to package directions until al dente. I check it a minute before the suggested time—you want it firm enough to hold up when tossed with the other ingredients. Drain well and rinse under cold water to stop the cooking process.

Spread the pasta on a baking sheet and let it cool completely to room temperature. This prevents the mayonnaise from breaking down when mixed with hot pasta. I find that stirring it occasionally speeds up the cooling and keeps the pieces from sticking together.

Step 2: Prep All Vegetables for Maximum Crunch

Halve the 2 cups Cherry Tomatoes and place them in a large bowl. Dice the 1 whole Cucumber into ½-inch pieces—peel it if you prefer a milder flavor. Thinly slice the 0.5 whole Red Onion for a sharp bite that mellows as the salad sits.

Dice the 1 whole Green Bell Pepper into similar-sized pieces as the cucumber. Slice the 0.5 cup Black Olives and chop the 0.25 cup Pepperoncini Peppers. Adding these all to the same bowl with the tomatoes lets the flavors start to meld while you make the dressing.

Step 3: Whisk Together the Signature Dressing

In a medium bowl, combine the 1 cup Mayonnaise, 0.25 cup Red Wine Vinegar, 0.5 cup Parmesan Cheese, 1 tbsp Sugar, 2 tsp Dried Italian Seasoning, 1 tsp Garlic Powder, 1 tsp Salt, and 0.5 tsp Black Pepper.

Whisk until the mixture is completely smooth and the parmesan is fully incorporated. Taste and adjust the seasoning if needed—I sometimes add an extra pinch of salt if the parmesan isn’t very salty. The dressing should be creamy with a slight tang from the vinegar.

Step 4: Combine and Chill for Best Flavor

Pour the cooled rotini into the bowl with the chopped vegetables. Add the dressing and fold everything together gently but thoroughly. You want every piece of pasta and every vegetable coated with the creamy dressing without breaking up the tomatoes or cucumbers.

Cover the bowl with plastic wrap and refrigerate for at least 2 hours before serving. This chilling time allows the flavors to develop and the pasta to absorb some of the dressing. I find that 4 hours is ideal—it tastes even better the next day for leftovers.

Step 5: Adjust and Serve

Give the pasta salad a good stir before serving. If it seems a bit dry, you can add a splash of milk or a spoonful of mayonnaise to loosen it up. The vegetables will release some liquid as they sit, which can make the salad a bit watery after a few hours.

This dish serves 6 and keeps well in the refrigerator for up to 3 days. The flavors actually improve as it sits, making it perfect for potlucks or meal prep. Serve it chilled for that authentic Olive Garden experience.

Storing and Reheating This Recipe

Fridge Storage

Transfer your pasta salad to airtight containers once fully chilled. I use glass Pyrex with snap-tight lids—they’re perfect for keeping the salad fresh and visible in the fridge. It’ll stay at peak flavor for 4-5 days at 40°F or below. ❄️

Freezer Not Recommended

This dish doesn’t freeze well because the mayonnaise in the dressing can separate and the vegetables turn mushy. If you must freeze, leave out the cucumbers and tomatoes, then add fresh ones after thawing. Even then, the texture won’t be the same.

Reviving Leftovers

Before serving leftovers, give the salad a good stir. If it seems dry, add 1-2 tbsp milk or mayonnaise to restore creaminess. The pasta soaks up dressing over time, so this little trick brings it back to life.

Room Temperature Serving

For the best texture, let the salad sit at room temperature for 15-20 minutes before serving. This softens the pasta slightly and makes the flavors pop. Just don’t leave it out for more than 2 hours for food safety.

Make-Ahead Tip

This recipe is perfect for meal prep. Make it a day ahead—the flavors meld beautifully overnight. Just hold off on adding the Parmesan until serving to prevent clumping. I always get compliments when I bring this to potlucks!

Avoiding Sogginess

If your salad gets watery from the veggies, drain off the excess liquid or stir in a little extra dressing. Using English cucumbers and seeding tomatoes helps minimize this, but it’s normal with fresh produce. 💡
