From my kitchen to yours

Salt-Roasted Baby Potatoes with Sour Cream Horseradish Sauce prove that the simplest ingredients can deliver the biggest flavor. Roasting baby potatoes in a generous bed of salt creates a crisp, flavorful skin while keeping the inside creamy and tender.

Paired with a cool, tangy sour cream horseradish sauce, these potatoes strike the perfect balance of richness and bite. Serve them as a crowd-pleasing appetizer or dramatic side dish for a restaurant-quality meal at home.

Serve with my Grilled Marinated Skirt Steak with Peperonata or Grilled Burgers with Bacon Jam!

CHEF tips AND TRICKS:

• Salt-roasting requires a large amount of salt. However, you don’t consume the salt, so ignore the sodium count in the nutritional analysis.
• Dry the potatoes well.  Pat them completely dry before salting to prevent sogginess.
• If possible, use mini or “peewee” potatoes such as the ones in my Garlic Butter Parmesan Mini Potatoes; they’ll cook faster because they’re so small.
• For the most part, the potatoes come right out of the salt; however, you may need to brush the salt off a few.
• What to do with all that salt!  Here are some ideas:
  • Use in a simple brine for chicken or turkey
  • Sprinkle over an icy patch on your sidewalk, driveway, or patio.
  • Keep it in a bucket in your kitchen to put out a small fire.
  • Save it to roast more potatoes!
