Grass-fed Beef Recipe

Blackened London Broil with Red Onion Marmalade

Blackened Steak


3 large Red onions, peeled and sliced 1/8 inch thick
1/2 cup sugar
1/3 cup balsamic or red wine vinegar
1/2 teaspoon crushed red pepper flakes
Juice of 1 lemon
Salt and ground black pepper, to taste
(1) 1 1/2-pound London broil
2 teaspoons Cajun seasoning


Saute the sliced onions and sugar in a large skillet over high heat, stirring occasionally, for about 10 minutes, until the juices from the onions have evaporated. Reduce heat to medium and cook, stirring constantly, until the onions are golden brown. Add the vinegar, crushed red pepper flakes, lemon juice and salt and pepper to taste and set aside until ready to serve.

Meanwhile, preheat your grill or broiler. Rub the steak with the seasonings and grill over medium-high heat for 5 to 7 minutes per side. Or, broil in the oven 6 inches from the heat about the same amount of time.
