Mix all the ingredients for the burger patties (ground beef through salt and pepper) in a medium bowl until everything is well mixed. Form the meat mixture into four hamburger patties or 8 smaller patties for sliders.
Step 2
Heat oil in a large skillet over medium-high heat. Gently place the patties in the skillet. Cook patties until cooked to desired doneness, 8–10 minutes, flipping once half way through. This may need to be done in batches. If desired, top patties with cheese and allow to melt before serving.
Step 3
Serve on buns with lettuce, tomato, onion, ketchup, mustard, and mayonnaise as desired.
