Ingredients

  • 1 lb. small red potatoes
  • 1 1/2 Tbsp. white wine vinegar
  • 1 Tbsp. country-style Dijon mustard
  • 1/2 tsp. salt
  • 3 Tbsp. olive oil
  • 2 scallions
  • 1/4 cup diced roasted red peppers

Instructions

  1. Cool the sliced red potatoes completely.
  2. In a large serving bowl, combine white wine vinegar, Dijon mustard, and salt to make the mustard dressing.
  3. Whisk in olive oil until the dressing is well blended.
  4. Add the cooled potatoes, sliced scallions, and diced roasted red peppers to the bowl.

Tips & Substitutions

For a creamier dressing, consider adding a dollop of Greek yogurt or mayonnaise. If you prefer a spicier kick, try using spicy brown mustard instead of Dijon. Ensure the potatoes are cooked just until fork-tender to maintain their shape in the salad. Fresh herbs like dill or parsley can enhance the flavor profile. This salad pairs beautifully with Homemade White Bread for a complete meal.

Serving Suggestions

Serve this mustard potato salad chilled as a refreshing side dish for barbecues or picnics. It complements grilled meats like chicken or burgers beautifully. For a complete meal, pair it with a light salad or a serving of Black-Eyed Pea Dip. This dish also works well for potlucks or family gatherings, making it a versatile addition to any spread.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. The flavors will meld and improve over time. To enjoy again, serve it cold straight from the fridge or let it sit at room temperature for about 15 minutes before serving. Avoid reheating as the texture may change.
