Hospitality House Holiday Prime Rib


The holidays are a time to celebrate community and all that we are grateful for.

BriarPatch Food Co-op is grateful for the hard-working folks at Hospitality House, a non-profit organization that provides food, shelter and other resources to the folks in our local community who are experiencing homelessness.

We’re thrilled to share their recipe for Prime Rib, just in time for the holidays! Check out the BriarPatch Meat Department for natural and sustainably raised Standing Rib Roasts.

  • 1 cup kosher salt
  • ¼ cup cracked black pepper

  • 15 garlic cloves

  1. Trim fat. Make 15 cuts through the top of the rib.
  2. Push a garlic clove into each cut. Mix remaining ingredients together and rub them over the top of the rib. Cover and place in the refrigerator for at least 10 hours.
  3. Preheat the oven to 350 degrees.
