Cajun Grass-fed Burgers With Carmelized Onions Recipe

Recipe Author: Sean Coonce | Pastured Kitchen

Summertime is grilling time and burgers are a summertime staple. Don’t be afraid to change up your recipe from time to time. Burgers are so flexible, you can add a seasoned rub or blend your seasonings into the ground meat before forming patties. Try these cajun burgers to mix things up.

In this recipe, Sean Coonce of Pastured Kitchen, uses a cajun rub he’s developed which gives the burgers a nice crust. This also helps keep the juiciness and flavor hidden away inside the burger.

Grass-fed ground beef has amazing flavor. Grass-fed meats are also leaner and require less time on heat. Watch your burgers and check internal temperatures to get the desired doneness. Take your burgers off the heat before they’re completely done. Remember, they’ll continue to cook after taking them off the grill or skillet.

Minimum recommended safe internal temperature for burgers is 160 deg F. See the temperatures below for cooking burgers.
Rare = 120 – 125 deg F
Med Rare = 130 – 135 deg F
Medium = 140 – 145 deg F
Med Well = 150 – 155 deg F
Well Done = 160 – 165 deg F
