This macaroni salad is a delightful and creamy dish perfect for picnics, barbecues, or as a side dish for any meal. The combination of mayonnaise, celery, and red onion gives it a refreshing crunch, while the mustard adds a tangy kick. It's a simple yet flavorful recipe that can be prepared in advance, making it a convenient option for busy days.
Most of the ingredients for this macaroni salad are common pantry items. However, if you don't usually keep celery or red onion on hand, you might need to pick them up at the supermarket. Fresh celery adds a crisp texture, and red onion provides a mild, sweet flavor that complements the other ingredients well.

Ingredients for Macaroni Salad Recipe
Macaroni: The base of the salad, providing a chewy texture that holds the dressing well.
Mayonnaise: Adds creaminess and richness to the salad, binding all the ingredients together.
Celery: Offers a crunchy texture and a fresh, slightly peppery flavor.
Red onion: Adds a mild, sweet flavor and a bit of color to the salad.
Mustard: Provides a tangy kick that balances the creaminess of the mayonnaise.
Salt: Enhances the overall flavor of the salad.
Black pepper: Adds a touch of heat and depth to the dish.
Technique Tip for Making This Salad
When preparing the macaroni, ensure you cook it al dente, as it will continue to absorb the dressing and soften slightly while chilling. To prevent the macaroni from sticking together after draining, toss it with a small amount of olive oil or rinse it briefly under cold water. This step helps maintain the salad's texture and prevents clumping.

How to Store or Freeze This Salad
- Store the macaroni salad in an airtight container to maintain its freshness and prevent it from absorbing any unwanted odors from the fridge.
- Keep the container in the refrigerator, ensuring the temperature is consistently below 40°F (4°C). This will help keep the mayonnaise and other ingredients safe to eat.
- For optimal flavor and texture, consume the macaroni salad within 3-5 days. The celery and red onion may lose their crunch over time, so it's best enjoyed sooner rather than later.
- If you need to freeze the macaroni salad, be aware that the mayonnaise might separate and the texture may change upon thawing. To freeze, transfer the salad to a freezer-safe container or heavy-duty freezer bag, removing as much air as possible.
- Label the container with the date to keep track of its storage time. Frozen macaroni salad can be kept for up to 2 months, but for the best quality, try to use it within 1 month.
- When ready to eat, thaw the macaroni salad in the refrigerator overnight. Stir well before serving to reincorporate any separated mayonnaise and adjust the seasoning if necessary.
- Avoid refreezing the macaroni salad once it has been thawed, as this can further degrade the quality and safety of the dish.
How to Reheat Leftovers
- Gently warm the macaroni salad in a skillet over low heat. Stir frequently to ensure even heating and to prevent the mayonnaise from separating.
- Place the macaroni salad in a microwave-safe dish. Cover it with a microwave-safe lid or plastic wrap, leaving a small vent. Heat on medium power for 1-2 minutes, stirring halfway through.
- For a cold option, refresh the macaroni salad by adding a bit more mayonnaise or a splash of lemon juice to revive its creamy texture and flavor.
