Cheese Stuffed Burgers with Onions and Mushrooms is scrumptious, easy and better than your steakhouse! A beef patty stuffed with cheesy cheddar cheese and topped with sautéed mushrooms and sweet caramelized onions!
Start to heat up the grill. Now either use a grill sheet (the perforated ones) with sliced onions and mushrooms, or skewer the onions and mushrooms for grilling. First, toss the onions and mushrooms with seasoning and oil, then grill over medium high heat with lid shut.
For the burgers: Mix all ingredients except cheese and divide the mixture into 4 pieces.
Flatten each piece and add a tablespoon of cheese in the center of each, then enclose the cheese and seal the beef around the edges.
Roll the patty slightly and re-flatten into a disc shape. Grill the patties for 4-6 minutes per side with the grill lid shut. The mushrooms and onions can be grilled side by side and ready at the same time.
If you're using a skillet. you'll need to heat up a non stick skillet and sauté the mushrooms and onions for nearly 8-10 minutes in olive oil after seasoning them. Remove them from the skillet but use the same one to pan fry your burgers in for a but of extra flavor too!
While the patties are cooking/grilling, you can begin spreading the buns with the condiments of your choice. Today I used: Ranch, Sriracha, avocados, arugula, salt and pepper. Extras: Tomatoes, more onions, greens, pickles, etc. Finally once the burger is ready, sprinkle some extra cheddar cheese over the top and it will melt naturally over the hot burger. So stack the cheeseburger over the bun and DIG in!!
