How To Make Hamburger with Double Cheddar Cheese, Grilled Vidalia Onion and Horseradish Mustard?
- Preheat the grill or skillet: Set your grill or a cast-iron skillet to high heat.
- Shape and season the patties: Divide the ground chuck into 8 equal portions (4 ounces each) and shape into patties. Season both sides with salt and black pepper.
- Cook the burgers: Grill or cook in the skillet for 3 to 4 minutes per side for medium-rare. During the last minute, place 2 slices of cheese (1 white and 1 yellow) on each patty, cover, and let melt for about 1 minute.
- Make the horseradish mustard: In a small bowl, whisk together Dijon mustard and horseradish until smooth.
- Grill the Vidalia onions: Brush both sides of the onion slices with olive oil and season with salt and pepper. Grill for 3 to 4 minutes per side until golden brown and tender.
- Assemble the burgers: Place each burger on a bun and top with horseradish mustard, romaine lettuce, grilled Vidalia onions, dill pickles, and ketchup.

Recipe Tips:
- Use high-quality ground beef: Choose 80/20 ground chuck for the best balance of fat and flavor. Lean beef can make the burgers dry.
- Shape the patties gently: Don’t press too hard when forming the patties. A light touch keeps them tender and juicy.
- Let the cheese melt properly: Cover the grill or pan after adding cheese so it melts evenly and gets extra gooey.
- Grill onions until soft and golden: Make sure the onions are cooked until soft and slightly caramelized for the best flavor. If they are undercooked, they will taste too sharp.
- Toast the buns for better texture: Lightly grill or toast the buns so they don’t get soggy from the juices and sauces. It adds a nice crunch too!
How To Store & Reheat Leftovers?
- Refrigerate: Let the burgers cool down first. Then, put them in a sealed container and store them in the fridge for up to 3 days. Keep the buns, onions, and sauce separate so they don’t get soft.
- Freeze: Wrap each burger patty in plastic wrap and place them in a freezer-safe bag. They will stay good for up to 3 months.
- Reheat: Heat a skillet over medium heat. Place the patty in the pan and cook for 2-3 minutes per side until heated through.
