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.2
When ready to cook, start the Traeger according to grill instructions. Set grill to 500F (Or High). Preheat (keep instructions from original recipe post).3
Cook for 3 minutes on each side for Medium Rare, 4 minutes on each side for Medium. Remove from heat when internal temp reaches 125F.4
The last few minutes of cooking, add provolone slices to burgers and place buns on grill to toast.
