When I think of stuffed burgers, the words juicy, cheesy, and crunchy come to mind, among other things. Everybody loves a cheesy, gooey burger, right? Putting the cheese inside the burger is even better, though. When you bite into an inside-out burger, it’s like a volcanic eruption of cheese (and other various ingredients, for example, I like to use diced bell peppers) in your mouth, gooey and melted and delicious.
Now the first question is, what kind of cheese to stuff inside? Any cheese will taste great, I’ve used many different kinds making these stuffed burgers over time (I’ve used pepper jack, cheddar, white cheddar, Monterey jack, etc.), but nothing comes close to the salty, mouth-watering flavor of feta cheese (at least, for me and my taste preferences).
Tasty and Easy Feta Stuffed Burgers with Caramelized Onions
- 2 medium yellow onion - sliced
- 2 tablespoons olive oil - plus more for brushing
- 2 pounds ground beef (minced beef) - hamburger mince
- 1 teaspoon paprika
- 1 teaspoon cayenne pepper
- 1 ½ teaspoon salt
- 1 ½ teaspoon ground black pepper
- 2 tablespoons green pepper (green capsicum) - diced
- 8 ounces feta cheese - crumbled
- 4 large leaves iceberg lettuce
- 4 large hamburger buns - cut in half
- Start the onions right away so they can caramelize while you’re cooking the burgers. Cut the onions into thick slices, shown below.
- Heat olive oil in a medium skillet to medium-low heat; add onions, salt and pepper. Allow cooking slowly, occasionally stirring, until caramelized, about 25-30 minutes.
- Next, the burgers: mix hamburger meat, paprika, cayenne pepper, salt and pepper (to taste) and chopped green pepper in a large bowl. Form small sections of meat into small, very thin hamburger-sized patties.
- Divide the feta cheese among the patties; try to form the feta into a sort of circle on the top of the patties.
- Cover each with another patty and pinch the edges together so that nothing seeps out the sides. Push down slightly in the middle of each patty so they don’t puff up on the grill/skillet (you should make roughly a ¼ inch indent).
- Heat grill/grill pan/skillet to medium or medium-high heat; brush with olive oil. Grill/cook burgers to desired ‘doneness’ (I like mine medium-rare); it should take roughly 10 minutes on the first side.
- Flip the burgers and finish cooking, about another 10 minutes.
- The caramelized onions should also be done.
- Serve w/ caramelized onions and lettuce on top of the burger. Enjoy!!
