Creamy Ranch Pasta Salad

My neighbor brought this pasta salad to our block party last summer, and I literally hovered over the bowl until she finally laughed and wrote down the recipe for me. The way the creamy ranch dressing clings to those rotini curves while the crunch of fresh peppers pops through somehow makes everything feel like a celebration, even on a regular Tuesday night.

I made this for my sister's baby shower when we were scrambling for something that would feed a crowd without requiring oven space. Watching my grandmother, who usually turns her nose up at 'modern' pasta salads, go back for seconds and actually ask for the recipe made all the vegetable chopping worth it.

Ingredients

• 340 g (12 oz) short pasta: Rotini, penne, or fusilli catch the dressing best in those little curves and ridges
• 1 cup cherry tomatoes: Halved so every bite gets that burst of sweetness
• 1 cup cucumber: Diced small adds incredible freshness without making things soggy
• 1/2 cup red bell pepper: Diced tiny for crunch and those gorgeous color pops
• 1/2 cup red onion: Finely chopped so you get just enough bite without overwhelming
• 1 cup frozen peas: Thawed first, they add sweetness and keep everything vibrant green
• 3/4 cup mayonnaise: The creamy base that makes this ranch sing
• 1/4 cup sour cream: Adds just enough tang to cut through the richness
• 3 tbsp buttermilk: Thins the dressing to perfect coating consistency while adding that classic ranch flavor
• 1 tbsp fresh dill: Chopped fresh makes such a difference, though dried works in a pinch
• 2 tbsp fresh chives: Their mild onion flavor plays so nicely with the dried herbs
• 1 tsp garlic powder: Even distribution of garlic flavor without any raw bite
• 1 tsp onion powder: Deepens that ranch flavor we all know and love
• 1/2 tsp dried parsley: Adds little flecks of green and classic herb notes
• 1/2 tsp salt: Enhances all the vegetables' natural flavors
• 1/4 tsp black pepper: Just enough warmth to balance the creamy dressing

Instructions

Cook and cool the pasta:

Bring a large pot of salted water to a boil and cook pasta until al dente, then drain and rinse under cold water until completely cool to the touch

Whisk up the ranch dressing:

In a large mixing bowl, combine mayonnaise, sour cream, buttermilk, dill, chives, garlic powder, onion powder, dried parsley, salt, and pepper until smooth and creamy

Combine everything:

Add the cooled pasta, cherry tomatoes, cucumber, red bell pepper, red onion, and peas to the bowl and toss gently until every piece is coated in that luscious dressing

Add the extras:

Fold in cheddar cheese and bacon if you are going the indulgent route

Let it rest:

Refrigerate for at least 1 hour so the flavors can meld and the dressing can really soak into the pasta

Final toss and serve:

Give everything one last gentle toss before serving and adjust seasoning if needed

Pin It

My three year old nephew who typically survives on a diet of air and crackers actually asked for seconds of this salad, which my sister still considers a minor miracle worth documenting.

Making It Lighter

Swap half or all of the mayonnaise for Greek yogurt, and the texture stays just as creamy while cutting the calories significantly.

Protein Boost

Diced cooked chicken turns this from a side dish into a complete meal that works beautifully for meal prep lunches throughout the week.

Make Ahead Magic

This pasta salad keeps beautifully in the refrigerator for up to two days, making it perfect for potlucks or busy weeknight sides.

• The pasta will absorb more dressing as it sits, so keep a little extra on hand for refreshing leftovers
• Wait to add bacon until just before serving if you want it to stay crispy
• Give everything a thorough stir before serving to redistribute any dressing that settled

Hope this becomes your go to for all those summer gatherings and lazy weeknight sides.

Recipe FAQs

→ How long should I chill the pasta salad?

Refrigerate for at least 1 hour before serving. This allows the dressing to absorb into the pasta and vegetables, enhancing the overall flavor. You can also make it up to 24 hours in advance.

→ Can I make this pasta salad ahead of time?

Yes, this salad actually tastes better when made a day ahead. The flavors have time to meld together. Store it in an airtight container in the refrigerator and give it a good stir before serving.

→ What type of pasta works best?

Short pasta shapes with ridges or hollows work wonderfully because they hold the dressing well. Rotini, penne, and fusilli are excellent choices that capture the creamy ranch in every bite.

→ How can I make this lighter?

Substitute Greek yogurt for some or all of the mayonnaise and sour cream. This reduces calories while adding protein and maintaining creaminess. You can also increase the vegetable ratio.

→ What vegetables can I add or substitute?

Beyond the classic mix, try adding diced carrots, broccoli florets, black olives, or shredded celery. For seasonal variations, incorporate fresh corn in summer or roasted bell peppers in fall.

→ Can I add protein to make it a complete meal?

Absolutely. Diced cooked chicken, grilled shrimp, or even chickpeas work beautifully. The bacon add-in mentioned provides protein, but grilled chicken breast makes it a substantial main dish.
