Grass-fed beef feed on grass and a mixture of other forage. This produces less marbling, but the fat produced has a greater percentage of healthy Omega 3 fats than Omega 6. The lower fat and the higher percentage of Omega 3s compared to Omega 6s changes the culinary performance of grass-fed beef: it cooks more quickly than corn fed beef and responds very well to high heat cooking.
To make great grass fed burgers on your Traeger:
Divide 2 lbs grass fed beef into four portions. To not to overwork the meat, remove from the package and directly shape into burger patties about 5” across – do not knead the meat. Sprinkle each burger with one teaspoon Kosher salt divided one half on each side.
When ready to cook, start the Traeger according to grill instructions. Set the temperature to 415 degrees F and preheat, lid closed, for 15 minutes.
Lay the hamburgers on the grill grate. Cook for 12 minutes then turn over and cook 12 minutes for a medium rare – the exterior should be nicely browned and a thermometer inserted into the center of the burger should register 130 degrees F.
The last few minutes of cooking, add provolone slices to burgers and place buns on grill to toast.
