I've got this cut of beef that I bought on sale that I'm not sure what to do with. I'm thinking of it for tomorrow's dinner and am looking for suggestions. It's labled Top Round Steak Thick - Beef for London Broil - USDA Choice. It's 3.10 lbs, not very marbled and at it's thickest point about 1.5 inches and thinnest .5 inch. Normally I'd pan sear it and then in the oven for a few minutes but I don't know how that'd work because it's thickness.
I searched the boards and found a lot of recommendations for grilling but the weather isn't cooperating so that's out. I've got time for a marinade and a long cook time isn't a problem. I just don't want to ruin it. Any ideas?
