Things You'll Need
2 pounds ground beef
1 teaspoon salt
1/4 teaspoon ground black pepper
Instant-read meat thermometer
The Nesco Roaster is a electric roaster oven that functions similarly to a traditional oven, but is small enough to fit comfortably on a tabletop and can be readily transported. If you want to make hamburgers but don't want to use a grill or frying pan, you can use the Nesco Roaster as long as you have access to an electrical outlet. Making hamburgers in a roaster oven can make them more likely to dry out due to the high temperature, but if you use the device correctly, they will cook properly and remain moist.
Plug in your Nesco Roaster and turn the dial to 350 degrees F. Add 2 pounds of ground beef, 1 teaspoon of salt, and 1/4 teaspoon of ground black pepper into a large mixing bowl.

Gently mix the ground beef with your hands until the salt and pepper is evenly distributed throughout the meat. Divide the mixture into four equal pieces for large burgers or six equal pieces for medium burgers. Mold each piece into a gently rounded patty shape.
Remove the roaster lid and transfer the patties directly onto the heating rack. Replace the lid and let the burgers heat undisturbed for three minutes.
Take off the lid and use a spatula to flip the burgers over. Put the lid back on and cook the burgers for another three minutes.
Transfer the burgers with a spatula onto a platter. Insert an instant-read meat thermometer into the center of a burger and ensure the thermometer measures at least 160 degrees F. If not, heat the burgers for another one to two minutes per side or until they reach160 degrees. Ttransfer them onto buns and serve.
Stir in 1/4 cup of chopped onions into the ground beef mixture before cooking to add extra flavor to the hamburgers.
If you want to make cheeseburgers, cover each burger with a slice of cheese during the last one to two minutes of cooking so it can melt slightly without overcooking.
Never consume ground beef that is not cooked to an internal temperature of at least 160 degrees F. It could contain dangerous, illness-causing bacteria, according to the United States Department of Agriculture.
