Storage Tips
Keep your potato salad fresh and tasty by storing it in an airtight container in the fridge. It stays good for 3-4 days. Just give it a quick stir before serving, as the dressing might settle a bit. If you’re taking it to a picnic, pack it in a cooler with ice packs to keep it nice and cold!
Variations
This classic potato salad is super flexible! Try adding crispy bacon bits for extra crunch, or mix in some fresh dill or chives for a pop of color and flavor. Not a fan of red onions? Sweet onions work great too.
You can also swap the yellow mustard for whole grain mustard to add some extra texture. For a lighter version, replace half the mayo with Greek yogurt – it’ll still be creamy and delicious!
Serving Suggestions
This potato salad is perfect for your next BBQ or family gathering! It pairs wonderfully with grilled meats, burgers, or hot dogs. Want to make it extra special? Sprinkle some paprika on top for a pretty finish, and add a few fresh herbs as garnish.
Serve it cold or at room temperature – both ways taste amazing. For a complete summer spread, serve it alongside some fresh coleslaw and baked beans.
Make-Ahead Tips
This potato salad actually gets better when the flavors have time to mix and mingle! You can make it up to 24 hours before serving. The potatoes will soak up all those yummy flavors from the dressing, making each bite even more delicious. Just be sure to keep it refrigerated until you’re ready to serve.
