Gluten Free London Broil with Balsamic Onion Marmalade Recipe

Some friends were in town this week visiting from Australia and the only chance we had to get together over a meal was on a week day. So I invited them for dinner and employed one of my favorite workday entertaining ploys.

I tossed together a quick gluten-free marinade in the morning, threw in a London Broil and fancied the cooked meat up with a sinfully lovely, gluten-free balsamic onion marmalade I had languishing in the fridge. With the addition of some roasted sweet potatoes, a fresh salad and some gluten-free Country Strawberry Shortcakes, we had ourselves a stress-free dinner party right smack dab in the middle of the week.

London Broil is economical, flavorful and lean. And super easy to prepare. It is a staple in our house since I can cook once and eat at least twice. I always have some left over which I turn into a main course salad or make steak sandwiches on gluten-free bread the next day.

Well known “secrets” to great London Broil are to marinate it and cut it across the grain. Marinating imparts flavor and correct carving yields tender slices. My secret is to glam it up with Balsamic Onion Marinade which can be made a week ahead, is good warm, room temp or cold and has dozens of uses. A favorite of mine is to put some on a gluten-free cracker, crumble on some goat cheese and top with a light sprinkle of fresh thyme.
