Grilled Flank Steak With a Warm Feta Sauce

Spread the love

I’m  not sure if this flank steak tasted so good because it’s been so long since I last had a steak or, it was just plain awesome. I’ll be off to Greece in a few days and I will not be eating steak there. I figured I’d get my steak fix now or wait 42 days until I return back to Toronto.

Flank steak is an affordable cut and it’s also known as London Broil. This cut of beef is a flat, long and usually rectangular in shape. It’s ideal for marinating and absolutely should be cooked on your grill…high heat for sure. The flank is the single muscle from the flank region beneath the loin and in front of the back legs. It’s boneless and a small one will feed two very well and a large steak will feed four generously.

Flanks steaks are a more affordable cut but they don’t let up with flavour and if seared over high heat, will remain tender. High heat, no more than two hours in the fridge marinated and grill over high heat to a medium-rare and you’ll be rewarded with a steak that is crisp on the outside and soft, pink and juicy on the inside.

If you’re the type that likes your steak done medium to well-done – don’t bother with this cut, it’s not for you. Pick another cut like a rib eye, which is still remarkably good when well done. The flank steak need only be licked by the high heat of your grill, quickly cooked and marinated.

I think one of the biggest errors people make with flank steak is marinating it for too long. Place in your fridge for two hours or one hour at room temperature. Marinating a flank steak beyond this time fram will break down the meat too much, making it mushy. Less is more.

I stuck with flavours that are familiar to my Greek palate: red wine, garlic, finely minced sun-dried tomatoes, lemon zest, olive oil, wine vinegar, mustard, fresh oregano and marjoram. Mix everything in a zip-lock plastic bag, marinate for no more than a couple of hours in the fridge grill after the meat’s returend to room temperature.

The icing on the steak was this quick and easy Feta sauce I made to accompany the flank steak. Olive oil, some flour for thickening, garlic, milk and crumbled Feta cheese are  that is need here. It’s a mild sauce, I didn’t want anything to interfere with the steak’s flavour, just a piquante complement to your meat. Looks good spooned over the flank steak, tastes a little tart with the rare steak.

This is an easy solution for your backyard entertaining. An affordable cut that doesn’t require much in preparation and it will allow to spend time with your guests, rather than off and away cooking for them. I served up  a packette of BBQ potatoes and some grilled corn, nothing too fussy.

Once again, the Skouras Agiorghitiko (St. George) red was an excellent pairing with this flank steak. This red has made many appearances on my table this year.

1/4 cup red wine

This was excellent the marinade and the warm feta sauce both complimented the steak, the Skouras Agiorghitiko wine was an added touch .


You always give me so many good ideas for using feta. Wish I’d seen this before I ate my steak dinner tonight. Have a great time in Greece. I know you’ll have lots to share with us when you get back.


Mr Minakis, this is too tempting for words…Love the rare steak with all the little caramelized bits on the outside…the sauce is just perfect!! Enjoy your vacation!


I have some flank steak in the freezer (missed it so much I bought a ton, lol) and I think one of the pieces might be getting the kalofagas treatment. Yum!


I grew up eating marinated flanksteak and I love it. Yours is perfectly cooked and that Feta Sauce – WOW!!! Fabulous as usual, Peter!


This just looks absolutely amazing! The sauce just seems like it would complement the steak so well. We’re off to a Greek for the day tomorrow (Kastellorizo) and we will no doubt be enjoying a huge, meaty dish, preferably of the pork variety!
