Cheddar Sour Cream Macaroni Salad – The Ultimate Creamy Potluck Favorite
When it comes to classic comfort side dishes, nothing beats a well-made macaroni salad. This Cheddar Sour Cream Macaroni Salad takes the traditional version and elevates it with a richer dressing, sharp cheddar cubes, and a tangy sour cream base that adds incredible depth.
Perfect for picnics, potlucks, barbecues, or simple family dinners, this recipe strikes the ideal balance between creamy, cheesy, and refreshing. Unlike overly sweet or heavy deli-style macaroni salads, this version tastes fresh, flavorful, and satisfying without being overwhelming.
The result is a crowd-pleasing side dish that pairs beautifully with grilled meats, sandwiches, and summer spreads — and it’s even better after chilling.

Why This Macaroni Salad Stands Out
Many macaroni salads rely solely on mayonnaise, but adding sour cream creates a smoother, lighter tang while boosting creaminess.
Tangy and balanced flavor
Sour cream cuts through richness and prevents the dressing from tasting too heavy.
Sharp cheddar bursts
Instead of melted cheese, this recipe uses cubes for texture and bold flavor.
Perfect make-ahead dish
The flavors deepen as it chills, making it ideal for preparing in advance.

The Secret to Perfect Macaroni Salad
Cool the pasta completely
Warm pasta absorbs too much dressing and can make the salad dry.
Salt the pasta water
This is the only chance to season the macaroni itself.
Cut ingredients small
Tiny pieces distribute better and create a balanced bite.
Chill before serving
The dressing thickens and flavors meld as it rests.

Flavor Variations
This salad adapts easily depending on the occasion.
Add protein
- Diced ham
- Cooked bacon bits
- Shredded chicken
Make it veggie-loaded
Add bell peppers, shredded carrots, or peas for color and crunch.
Give it a smoky twist
Use smoked cheddar or add smoked paprika.
Add sweetness
A spoonful of honey or sweet relish creates a classic deli-style flavor.
Serving Suggestions
This macaroni salad pairs beautifully with many meals.
Serve with:
- Grilled chicken or burgers
- BBQ ribs
- Pulled beef sandwiches
- Fried chicken
- Picnic sandwiches
For presentation, serve in a wide bowl topped with fresh chives and a light sprinkle of paprika.
Storage Tips
Refrigerator
Store in an airtight container for up to 4 days.
Refreshing leftovers
If it thickens too much, stir in a spoonful of sour cream or milk.
Do not freeze
The dressing separates after thawing.
Nutritional Highlights
