Mushroom and Feta Stuffed Gourmet Burgers

Yes, you can enjoy gourmet burgers stuffed with mushrooms and feta on a weeknight. With this handy tool, you'll be shaping perfect beef patties in no time.


  • 6 oz white mushrooms
  • 1 tablespoon olive oil, or bacon fat
  • 1 teaspoon Worcestershire sauce
  • 4 oz crumbled feta cheese
  • 1 1/2 lbs ground beef, 80/20
  • 1 teaspoon kosher salt
  • 1 teaspoon black pepper, or favorite burger seasoning or your choice
  • 4 hamburger buns
  • 4 tablespoons butter, or mayo


  • TO MAKE THE FILLING, cut mushrooms into small pieces.
  • Heat a large skillet over medium high heat.
  • Add oil.
  • Once oil is hot, add chopped mushrooms and Worcestershire sauce. Cook until mushrooms nicely browned, 8-10 minutes, stirring occasionally. Remove from heat and cool.
  • Mix cooled mushroom with feta cheese.
  • TO SHAPE THE BURGERS, divide beef into 8 equal parts, 3oz each, and then flatten each one into thin patties, about ¼-inch thick.
  • Place the mushroom and feta filling in the middle of 4 patties. Then top them with the other 4 smaller patties and seal the edges. (To make this process much easier, use this burger press. Read the directions in NOTES 1.)
  • Season the burgers with salt and pepper, or your favorite burger seasoning.
  • Heat the grill to medium heat for at least 5 minutes.
  • TO COOK THE BURGERS, grill the burgers over medium heat until cooked through, about 4 minutes per side. (Aim for 160°F internal temperature.)
  • Meanwhile, butter the buns and toast lightly over low heat until golden brown and crispy.
  • Serve the burgers on prepared toasted buns with other desired toppings and garnishes.


Note 1: If you’re using a burger press, like this one, divide the meat into 4 x 4oz and 4 x 2oz balls. Then place 4oz meat into the bottom of the press, flatten it using the press for stuffed burger, making a well in the middle. Fill with quarter of the filling and then place 2oz meat on top and push with flat press.
