This creamy Tuna Macaroni Salad brings together tender pasta salty tuna and colorful peas for the ultimate crowd-pleaser side or light meal. I love how it comes together quickly with simple ingredients but always feels nostalgic and satisfying at family gatherings or quick weekday lunches.
The first time I made this salad for a summer barbecue it disappeared long before the hot dogs and burgers. Now my friends always ask if I am bringing it to the party.
Ingredients
- Elbow macaroni: Brings a chewy mild base that soaks up creamy dressing Use a sturdy brand for best results
- Red onion: Chopped for a punch of color and sweet sharp flavor Choose onions with shiny even skins
- Celery: Adds cool crunch and helps balance the creaminess Look for stalks that feel crisp and firm
- Frozen peas: Sweet and fresh flavor plus pretty color Go for flash-frozen peas for best texture
- Tuna: Packed in water for flakiness and lean flavor Pick a firm light tuna with no fishy smell
- Mayonnaise: Rich and tangy to bind every bite Choose real full-fat mayonnaise for the creamiest result
- Sour cream: Lightens the dressing with gentle tang Use fresh with no graininess
- Sweet pickle relish: Gives a pop of sweetness and vinegar Select pickles made without additives for clean taste
- Salt: Brings all the flavors together Use kosher salt for easier seasoning control
- Black pepper: Adds gentle heat and earthy finish Use freshly cracked for best flavor
Step-by-Step Instructions
- Cook the Pasta:
- Boil elbow macaroni in heavily salted water until al dente Stir occasionally so nothing sticks After draining rinse pasta under very cold water to stop cooking and keep it from sticking together
- Prep and Combine Ingredients:
- Chop red onion and celery as finely as you can for best texture Run frozen peas under hot tap water then drain thoroughly Layer the cooked pasta tuna peas onion celery mayonnaise sour cream sweet relish salt and pepper into a very large mixing bowl
- Mix the Salad:
- Toss everything slowly and gently with a big spoon until the salad looks evenly coated Try not to crush the tuna or peas If it appears a bit dry you can fold in a spoon more mayo
- Chill and Serve:
- Cover tightly and refrigerate at least two hours The flavors meld and the pasta soaks up dressing Just before serving stir again and check seasoning

I always look forward to the sweet pickle relish here It is a simple ingredient but it gives the entire salad a little lift and brightness My cousin once tried to sneak a scoop before I finished mixing because she could already smell the tangy pickles
Storage Tips
Keep any leftover salad chilled tightly covered in the refrigerator It should be enjoyed within about five days for best taste and texture Be sure to stir before serving leftovers as the dressing can settle over time This recipe does not freeze well because pasta and mayo tend to separate and go mushy after thawing
Ingredient Substitutions
Feel free to use canned salmon or cooked chicken if tuna is not your thing Greek yogurt can stand in for sour cream for extra protein and a lighter dressing If you only have shell pasta or rotini those shapes will also hold dressing nicely For a different zing use chopped dill pickles rather than sweet relish

Serving Suggestions
This salad works great as a make-ahead lunch Add it to school lunchboxes with crisp veggies or serve on a bed of fresh romaine at dinner It also shines at summer picnics potlucks or holiday buffets Try pairing with grilled corn or watermelon for that backyard classic experience
Cultural and Historical Notes
Tuna macaroni salad is a staple in many American kitchens It became especially popular after mid-century canned goods made quick salads fashionable The mix of creamy dressing with economical proteins like tuna shows off how home cooks got creative with pantry basics to feed a crowd affordably
