Add the beef to a large bowl, and let it sit for about 10-20 minutes at room temperature.
Add the salt, pepper, Worcestershire sauce, paprika, garlic, onion, eggs and almond flour.
Mix well with your hands just until combined and all the ingredients are distributed evenly throughout the mixture.
Divide the mixture into 6 balls that are exactly the same size. Use a burger press to form the burgers into a patty shape, or use your hands to pack the burgers into evenly shaped patties. Place a small divot in the middle of one side of each of the burgers to prevent them from shrinking while grilling.
Chill the patties in the fridge for about 30 minutes before placing them on the grill.
Grill over medium-high heat (or fry in a frying pan over medium-high heat) for about 5-6 minutes per side, or until the internal temperature of the burgers reach 160 degrees Fahrenheit (71 Celsius) measured with an instant read thermometer.
Remove the burgers from the heat and let them sit for about 5 minutes before serving. This helps them stay juicy and prevents them from falling apart.
