Ingredients For Sweet Potato Potato Salad Recipe
Sweet potatoes: These provide a natural sweetness and vibrant color to the salad.
Russet potatoes: These add a hearty, starchy texture that complements the sweet potatoes.

Dijon mustard: Adds a tangy, slightly spicy flavor to the dressing.
Salt: Enhances the overall flavor of the salad.

Technique Tip for This Recipe
When boiling the sweet potatoes and russet potatoes, make sure to cut them into evenly sized cubes. This ensures that they cook at the same rate, preventing some pieces from becoming too mushy while others remain undercooked. Additionally, start with cold water and bring it to a boil with the potatoes already in the pot. This helps them cook more evenly and prevents the outside from becoming overcooked before the inside is tender.

How To Store / Freeze This Dish
Ensure the sweet potato potato salad is completely cooled before storing. This helps maintain the texture and prevents condensation, which can make the salad watery.
Transfer the salad to an airtight container. This will keep the mayonnaise dressing fresh and prevent the salad from absorbing any unwanted odors from the refrigerator.
Store the container in the refrigerator. The salad will stay fresh for up to 3-4 days. Always give it a quick stir before serving to redistribute the dressing and ensure even flavor.
If you plan to freeze the salad, be aware that the texture of the potatoes may change slightly upon thawing. The mayonnaise dressing can also separate, but this can be remedied by stirring well after thawing.
To freeze, place the salad in a freezer-safe container or a heavy-duty freezer bag. Squeeze out as much air as possible to prevent freezer burn.
Label the container with the date to keep track of its freshness. The salad can be frozen for up to 1 month.
When ready to use, thaw the salad in the refrigerator overnight. Once thawed, give it a good stir to reincorporate the dressing and adjust the seasoning if necessary.
