Gluten Free Short Rib Burgers with Caramelized Onions
I love the Fourth of July!
Friends and family coming together to celebrate freedom with really great food – what could be better?
For me, the Fourth of July menu has got to include two things: hamburgers and potato salad. After that, everything else is a bonus.
I have to tell you that this gluten free short rib burgers with caramelized onions recipe is hands-down the very best burger I have ever made!
The secret is in the meat, a combination of ground skirt steak and short ribs. Go to your butcher and have him grind both meats together in a medium grind. If you can only get short ribs on the bone, no worries. Have the butcher just cut it off for you before grinding.
Trust me on this burger – it is worth a celebration all by itself.
Happy Fourth of July!
Short Rib Burgers with Caramelized Onions
- 2 ½ pounds white or yellow onions 3 large
- 2 tablespoons unsalted butter
- 2 tablespoons olive oil
- Kosher salt
- Freshly ground black pepper
- 4 sprigs fresh thyme
- 2 tablespoons balsamic vinegar
- ¾ cup mayonnaise
- 2 tablespoons sriracha sauce
- 1 pound ground boneless beef short ribs
- 1 pound ground skirt steak or tri-tip
- Vegetable oil
- 6 gluten free Kaiser rolls or hamburger buns
- 3 tablespoons melted butter
- 6 lettuce leaves
- 6 slices tomato
- Cut onions in half and slice thinly. Heat butter and oil together in a large skillet over medium low heat. Add the sliced onions, ½ teaspoon salt, ¼ teaspoon pepper, and thyme. Cook the onions slowly, stirring occasionally, until deeply browned and caramelized, about 45 minutes. Remove the thyme sprigs, raise heat to high, and add the balsamic vinegar. Cook, stirring, until all the vinegar has evaporated. Can be made several days ahead, store in a covered container in the refrigerator. Reheat in microwave or on stove-top before using.
- Mix the mayonnaise and sriracha together until fully combined. Refrigerate until ready to serve.
- Prepare the grill for direct heat. Combine the ground meats. Divide into 6 equal portions and shape into patties about ¾-inch thick. Make a deep depression in the center of the patties. Brush both sides of the patties with oil and season with salt and pepper. Grill for 4 minutes, flip the burgers and grill for another 4 – 5 minutes for medium-rare.
- Cut the Kaiser rolls in half, spread the cut surfaces with melted butter and grill for 1 – 2 minutes.
- To serve, spread the bottom roll with some of the mayonnaise mixture, top with lettuce, a tomato slice, burger patty, and some caramelized onions.
