Sour Cream Pasta Salad is the kind of cool, creamy side dish that disappears fast at potlucks, cookouts, and weeknight dinners. Tender elbow macaroni gets tossed with crisp red bell pepper, minced celery, and sliced scallions, then coated in a tangy sour cream and mayonnaise dressing with a whisper of smoked paprika. It takes about 30 minutes from start to finish, and most of that is hands-off while the pasta cooks and cools. The dressing needs no special equipment—just a bowl and a whisk—and the whole salad tastes even better after a short chill in the fridge.

Why This Sour Cream Pasta Salad Works

This recipe delivers a creamy, crunchy, and tangy pasta salad that holds up well on a buffet table and tastes fresh even after a few hours.

• Perfect creamy-tangy balance: Full-fat sour cream and real mayonnaise create a rich, velvety dressing, while apple cider vinegar and a touch of sugar brighten every bite without making it sweet.
• Crunchy vegetables in every forkful: Diced red bell pepper, minced celery, and thinly sliced scallions stay crisp even after the salad is dressed, adding fresh texture and color.
• Make-ahead friendly: The flavors meld beautifully in the fridge, so you can prepare it a day ahead and simply stir in a splash of milk before serving to restore the creamy consistency.
• No fancy equipment needed: One pot for the pasta, one large bowl for mixing, and a whisk are all you need—cleanup is quick and the method is straightforward.
• Versatile base recipe: You can easily swap in different vegetables, add protein, or adjust the tanginess to suit your crowd, making it a reliable go-to for any gathering.

Ingredients Notes

• Elbow Macaroni (1 lb): Cook the pasta just until al dente in well-salted water. Rinsing it under cold water stops the cooking and removes excess starch so the dressing clings without turning gummy.
• Sour Cream (1 cup, full-fat): Full-fat sour cream gives the dressing its signature tang and velvety body. I don’t recommend light sour cream here—it can make the dressing watery as it sits.
• Mayonnaise (½ cup, real mayo): Real mayonnaise adds richness and helps the dressing coat every piece of pasta smoothly. In my kitchen, a good-quality store-bought mayo works perfectly.
• Apple Cider Vinegar (1 tbsp): This brightens the whole salad and cuts through the richness of the sour cream and mayo. White wine vinegar or a squeeze of fresh lemon juice can work in a pinch.
• Granulated Sugar (1 tsp): Just a teaspoon balances the tang without making the dressing sweet. You can leave it out if you prefer a sharper flavor.
• Fine Sea Salt (1 tsp): Season the dressing well—pasta salads need a confident amount of salt to bring all the flavors forward. Taste and adjust before adding the vegetables.
• Red Bell Pepper (1 large, diced small): Dicing the pepper into uniform small pieces ensures you get a little crunch and sweetness in every bite. Any color bell pepper works, but red is the sweetest.
• Celery (2 stalks, minced): Mincing the celery finely distributes its fresh, peppery crunch without leaving big watery chunks. If your stalks are very wide, slice them lengthwise first.
• Scallions (4 whole, thinly sliced): Use both the white and green parts for mild onion flavor and a pop of color. Slice them just before adding so they stay bright and crisp.
• Smoked Paprika (½ tsp, for dusting): A light dusting over the finished salad adds a subtle smoky note and makes it look beautiful. Sweet paprika or a pinch of cayenne can be used instead.
• Coarse Ground Black Pepper (½ tsp): Freshly ground black pepper adds a gentle warmth. Add it to the dressing along with the salt so it disperses evenly.
• Fresh Parsley (¼ cup, chopped): Flat-leaf parsley adds a fresh, herbal finish. Stir most of it into the salad and save a little for garnish right before serving.

Before You Begin

• Cook the pasta al dente: Boil the elbow macaroni in generously salted water according to package directions, then drain and rinse under cold water until cool. Shake off excess water well so the dressing isn’t diluted.
• Prep all vegetables first: Dice the bell pepper, mince the celery, slice the scallions, and chop the parsley before you start mixing. Having everything ready makes assembly quick and prevents the dressing from sitting too long.
• Use a large mixing bowl: Choose a bowl big enough to toss all the ingredients without spilling. A wide, shallow bowl makes it easier to fold the dressing through the pasta evenly.
• Chill the salad before serving: While you can serve it right away, letting the salad rest in the fridge for at least 30 minutes allows the flavors to meld and the dressing to thicken slightly.

How to Make Sour Cream Pasta Salad

• Step 1 – Cook and Cool the Pasta: Bring a large pot of salted water to a boil. Add the elbow macaroni and cook until al dente. Drain, rinse under cold water until completely cool, and shake off excess water. Set aside.
• Step 2 – Make the Creamy Dressing: In a large mixing bowl, whisk together the sour cream, mayonnaise, apple cider vinegar, sugar, salt, and black pepper until smooth and well combined. Taste and adjust salt or vinegar if needed.
• Step 3 – Add the Vegetables: To the dressing, add the diced red bell pepper, minced celery, sliced scallions, and most of the chopped parsley. Stir until the vegetables are evenly coated.
• Step 4 – Fold in the Pasta: Add the cooled macaroni to the bowl. Use a large spatula or wooden spoon to gently fold everything together until the pasta is evenly coated with the dressing and the vegetables are distributed throughout.
• Step 5 – Chill and Finish: Cover the bowl and refrigerate for at least 30 minutes, or up to overnight. Before serving, stir the salad, taste for seasoning, and add a splash of milk or reserved pasta water if it needs loosening. Transfer to a serving dish, dust lightly with smoked paprika, and garnish with the remaining parsley.

How to Know It’s Done

• Pasta is tender but firm: The macaroni should be cooked al dente—soft enough to bite through easily but still holding its shape without turning mushy. Overcooked pasta will break apart when you fold the salad.
• Dressing clings to every piece: After folding, the dressing should coat the pasta and vegetables evenly without pooling at the bottom of the bowl. If it looks dry, stir in a little milk or reserved pasta water.
• Vegetables stay crisp and bright: The bell pepper and celery should still have a noticeable crunch, and the scallions should look fresh and green. If they’ve softened too much, the salad may have sat at room temperature too long before chilling.
• Flavors taste balanced: The tang from the sour cream and vinegar should be mellowed by the richness of the mayo and the sweetness of the bell pepper. Taste and add a pinch more salt or a drop of vinegar if it needs a lift.

Nora’s Tips for Best Results

• Salt the pasta water well: This is your first chance to season the salad. I use about 1 tablespoon of fine sea salt per pound of pasta—it should taste like the ocean.
• Rinse the pasta thoroughly: Cooling the macaroni under cold water stops the cooking and washes away surface starch. This keeps the salad creamy instead of sticky.
• Dice vegetables uniformly small: Keeping the bell pepper and celery pieces about the size of a pencil eraser ensures they mix evenly and you get a little crunch in every bite.
• Chill before adjusting seasoning: Cold dulls flavors slightly, so the salad may taste perfectly seasoned at room temperature but need a pinch more salt after chilling. I always taste it cold and adjust right before serving.
• Don’t skip the smoked paprika dusting: It adds a subtle smoky aroma that makes the salad feel a little more special. A fine-mesh strainer helps you dust it evenly over the top.

Storage & Leftovers Tips

• Refrigerate promptly: Store leftover pasta salad in an airtight container in the fridge within 2 hours of serving. It will keep well for up to 4 days.
• Revive the creaminess: The pasta absorbs dressing as it sits, so stir in a tablespoon or two of milk, buttermilk, or reserved pasta water before serving leftovers to bring back the creamy texture.
• Freezing is not recommended: The sour cream and mayonnaise dressing can separate and become watery when thawed, and the vegetables will lose their crunch. This salad is best enjoyed fresh or within a few days.
• Serve chilled or cool room temperature: For food safety, don’t leave the salad out at room temperature for more than 2 hours. If serving outdoors on a hot day, nest the bowl in a larger bowl of ice.

Variations & Substitutions

• Add protein for a main dish: Fold in 1 cup of diced cooked ham, shredded rotisserie chicken, or crumbled bacon to turn this side salad into a satisfying lunch or light dinner.
• Swap the vegetables: Use diced cucumber, shredded carrot, or halved cherry tomatoes in place of or in addition to the bell pepper and celery. Just pat watery vegetables dry before adding.
• Make it tangier: Replace the apple cider vinegar with an equal amount of dill pickle juice or add 2 tablespoons of finely chopped dill pickles for a briny, zippy twist.
• Try a different herb: Fresh dill, chives, or basil can replace the parsley. Dill pairs especially well with the sour cream dressing and gives the salad a classic deli-style flavor.
• Use Greek yogurt: For a lighter, tangier dressing, swap up to half of the sour cream with plain full-fat Greek yogurt. Avoid nonfat yogurt, which can make the dressing thin and watery.

What to Serve With Sour Cream Pasta Salad

• Grilled barbecue chicken: The cool, creamy salad balances smoky, charred chicken thighs or drumsticks perfectly. Serve them side by side at your next cookout.
• Juicy burgers or sliders: A scoop of this pasta salad alongside a classic cheeseburger or pulled pork slider makes a complete, crowd-pleasing plate.
• Crispy fried fish: The tangy dressing cuts through the richness of fried catfish or fish sticks, adding a fresh contrast to a fish fry or weeknight fish dinner.
• Grilled sausages or brats: Serve the salad with grilled bratwurst or smoked sausage, plus a drizzle of mustard, for an easy, hearty meal.
• Fresh fruit or a simple green salad: Round out a potluck spread with a bowl of watermelon chunks or a light arugula salad dressed with lemon vinaigrette.
