Grilled Marinated Flank Steak with Caramelized Onions

I find any time of the year is perfect for grilling. Lucky for me, I have my grill strategically placed so I can get to it anytime of the year. I guess not having access to a grill for many many years while living in NYC, I feel compelled to grill whenever I can.

Check out my Grill Tips for information on grilling and check out my Tools & Gadgets for some great grill tools that are a must for any serious grill master.

Grilling beef over fire goes back a long time and may still be the best way to cook it. Maybe it’s the smoky flavor, or maybe it’s the sound of the sizzle while cooking, but eating a steak right off the grill is definitely one of my favorite ways of preparing beef.

There are many different cuts of beef and each should be prepared in it’s own way to bring out the maximum flavor. Generally, lean steaks should be marinated and cooked quickly so they don’t overcook and become tough.

Very tender cuts like the tenderloin and filet Mignon can be lightly oiled, seasoned with salt and pepper and thrown on the grill. For this recipe, I used a lean flank steak marinated in soy, sherry, and Dijon mustard.

I originally posted this recipe with a mistake. I said to marinate the beef and then use the same marinade later to baste the beef while grilling.

It was brought to my attention that this is not wise because “Surface bacteria, including all the nasty ones, propagate in the marinade. When you smear them back onto the surface of the meat, you re contaminate the meat with bacteria.” So I changed the recipe to as follows.

Reluctant Gourmet’s Tips

Be sure your grill is hot enough before starting.

Grill meat and veggies about 4 inches from heat source.

To add more flavor, try adding pre soaked chunks of natural hardwoods like Hickory.

Make sure grill is clean before cooking.

To prevent sticking, brush or spray a light coating of oil on grid.

If your grill has a top, close it to allow smoke to add it’s flavor.

How To Prepare At Home

Not a lot of prep for this grilled steak and caramelized onions recipe. Just be sure to have all the ingredients on hand and ready to go. Peel and slice the onions and make or defrost the chicken stock.

Marinated Steak

Mix the marinated ingredients together in a large, shallow glass bowl. Remove 1/4 of the marinade and reserve for basting. Gently score the flank steak and add to the marinade, cover, and let sit at room temperature for 1-2 hours or refrigerate if marinating longer. Fire up your grill and when it's ready remove the steak from the marinade and grill for about 5 minutes per side.

Discard the marinade and use the reserve marinade to baste.

Caramelized Onions

Heat the butter and oil in a heavy bottomed pan until they are almost smoking hot. Add the onions and sauté until translucent ...approximately 10 to 15 minutes. Add the brown sugar and stock, season with salt and pepper, reduce heat and simmer until all the liquid is absorbed.

To Serve

Slice steak into 1/4 inch pieces, top with onions and serve. Of course a hearty red wine goes great with this meal as well as side dishes like roasted potatoes and grilled veggies.
