I love a fancy burger. Ok, I love any burger. I am a burger eatin' girl!! This is a fun way to eat a burger because the cheese is hiding inside the patty instead of on top. We used Swiss but you can totally use any type of cheese you like...we've tried it with Cheddar, Bleu Cheese, Monty Jack, Pepper Jack...go nuts! Burger season has arrived!
1 pound ground beef
3 tablespoons Montreal Steak Seasoning
3 tablespoons A-1 Sauce
1/2 pound Swiss cheese, divided
1 onion, chopped
1 pint of mushrooms, chopped
Extra Virgin Olive Oil (EVOO)
Salt and Pepper
In a medium sized bowl, combine ground beef with steak seasoning and A-1. Divide into four pieces. Take a fourth of your cheese and roll it into a ball. Build each burger portion around the cheese (so that the cheese is in the middle). Flatten out your patties to a burger shape. You should get four burgers.
On a preheated outdoor grill or indoor grill pan, cook burgers over medium-high heat about 5 minutes per side (longer if you like your burgers more well done).
Meanwhile, in a large skillet over medium-high heat, saute your onion and mushrooms in a few tablespoons of EVOO. Do not salt and pepper them until the mushrooms have completely browned. Salting mushrooms too early draws out their water and it takes them way longer to brown up. Saute about 15 minutes or until onions and mushrooms have caramelized and browned up nicely. Now, season with salt and pepper.
Take each burger bun and top it with one patty. Then top each patty with your onions and mushrooms. When you bite into your burger, you'll get a nice, gooey, Swiss cheesy center. Delish!
