Servings: 8 Servings
Ingredients
- slices of cooked prime rib see above for links to recipes
- buns of your choice
Caramelized Onions:
- 4 large sweet onions halved and cut thinly
- ¼ cup butter
- ¼ teaspoon salt
- fresh ground pepper
- 3 – 4 tablespoon balsamic vinegar
- 3 – 4 tablespoon brown sugar
- 6 fresh rosemary stems
- 2 bay leaves
Horseradish Cream Sauce:
- 2 tablespoon prepared horseradish
- ¼ cup sour cream
- 2 teaspoon Worcestershire sauce
- 2 teaspoon Sriracha
Instructions
Caramelized Onions:
- Cut the onions in half, then slice them thinly.
- Melt the butter in a large skillet, then add the onions.
- Cook over low-medium heat until the onions are softened. About 15 minutes.
- Then add the rosemary stems and bay leaves. Mix. Cook for about 20 more minutes, until the rosemary has wilted.
- Once the rosemary has wilted, remove it and the bay leaves. You will likely have to remove stray rosemary leaves.
- Stir in the balsamic vinegar, sugar, salt and pepper.
- Continue cooking until the liquid is all gone, and the onions are caramel coloured and soft. Be very careful not to burn the mixture, so stir often.
Horseradish Cream Sauce:
- Combine the horseradish, sour cream, Worcestershire sauce and Sriracha. I like to use a hand blender to make the sauce nice and creamy.
Putting it all together:
- Add slices of cooked prime rib to a bun, add a scoop of caramelized onions and drizzle with the horseradish cream sauce. If you have gravy from the prime rib pan drippings, add that too, it will kick it up a knotch!
- Serve immediately and enjoy!
