In a mixing bowl, combine the ground beef, kosher salt, black pepper, onion powder, garlic powder, smoked paprika and chili.
Gently press the beef mixture into an ungreased glass square 8-inch pan.
Bake until cooked through, 12-15 minutes. A meat thermometer should read 160 degrees F.
If there's a lot of cooking liquid in the pan, you can drain some. I like to keep it and allow some of it to get absorbed back into the burgers as they rest.
Top the cooked meat with the cheese slices, as shown in the video below. Return the pan to the oven and bake just until cheese is melted, 1-2 minutes.
Remove the pan from the oven and allow to rest and set for 5 minutes. Cut into four squares and serve.
You can experiment with different spices. A pinch of thyme is good, and I also like to add a pinch of cumin.Please don't go below a lean-to-fat ratio of 85/15. Any leaner than that and the meat will turn out extremely dry. You can keep the leftovers in the fridge, in a sealed container, for 3-4 days. You can reheat them gently in the microwave at 50% power.
