How to Make It
Start creating your burgers with these simple steps.
Mix the Sauce
Combine the mayonnaise, ketchup, mustard, pickled okra, okra brine, vinegar, garlic powder, kosher salt, and black pepper in a bowl. Stir well until smooth and set aside.
Prepare the Beef
In a large bowl, mix the ground beef with kosher salt and black pepper. Make sure not to overwork the meat for a tender burger.
Shape the Patties
Divide the beef mixture into four equal parts, gently forming each portion into a ball. Do not press them too hard; they should remain loose.
Smash the Patties
Preheat your grill or griddle over medium-high heat. Place the beef balls onto the hot surface and smash them with a spatula until about 1/2 inch thick. Sear for 3-4 minutes until a crust forms, then flip.
Add Cheese and Cook Onions
Place a slice of cheese on each patty after flipping. In a separate skillet, add a bit of oil and cook the sliced onions over medium heat until they are caramelized and soft, about 6-8 minutes.
Assemble and Serve
On each brioche bun, spread a generous amount of the sauce, add the cheese burger patty, top with jalapeño rings and caramelized onions, then close the bun. Serve hot.
How to Store It
Fridge: store in an airtight container for up to 3 days.
Freezer: yes, up to 3 months.
Reheat: microwave for 1-2 minutes until warmed through.
Tips for Best Results
- Make sure your grill or skillet is hot before adding the patties for the best sear.
- Allow the patties to rest for a minute after cooking; this keeps them juicy.
- Customize the sauce to your preference by adjusting the pickled okra and spices.
- Use fresh, high-quality ground beef for the best flavor and texture.
Serving Suggestions
- Pair with crispy french fries for a classic combo.
- Serve alongside a fresh garden salad for a lighter option.
