- Preheat oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease a baking dish.
- Mix the base: In a large bowl, combine ground beef, egg, milk, breadcrumbs, onion, garlic, salt, pepper, paprika, and oregano.
- Add flavor and cheese: Gently mix in shredded cheese and ketchup, being careful not to overwork the meat.
- Shape the patties: Form the mixture into flat, round patties and place them on the prepared baking sheet.
- Lightly brush the tops with olive oil.
- Bake uncovered for 20 minutes.
- Optional finish: Sprinkle additional cheese over the patties and return to the oven for 5 minutes, until melted and the patties are cooked through.
- Rest and serve: Let the patties rest for 5 minutes before serving.
Delicious with roasted vegetables, a fresh green salad, or served on buns for an easy cheesy burger-style meal.
