Flap Steak with Garlic Yoghurt and Crispy Potatoes

Flap steak and skirt steak are not the same cut. Flap steak comes from the bottom sirloin, known in France as bavette d'aloyau, in the UK as flap meat, and in the US as sirloin flap. This pan-seared flap steak with garlic yoghurt brings out its bold, beefy flavor with a creamy, cooling sauce alongside golden crispy potatoes.

Bavette is one of those cuts that rewards a little attention. It has a distinct grain, a rich beefy flavor, and enough marbling to stay juicy through a hard sear. As a pan-seared steak, it performs well above its price. One whole bavette comfortably feeds four. If you are cooking for two, cut it in half before searing and save the rest for another day.

Before the steak goes into the pan, pat it completely dry with kitchen paper. Moisture on the surface prevents browning. Season with salt and black pepper just before it hits the pan, not in advance. A stainless steel or cast iron skillet over high heat is what you need. The pan has to be very hot before the bavette goes in.

The flap steak cooks for 5 to 6 minutes total, depending on thickness, for a medium-rare result. Flip it every minute rather than leaving it on one side. That technique builds an even crust across the entire surface while keeping the center pink and juicy. Once done, transfer the steak to a cutting board and let it rest for 5 minutes. Resting keeps the juices inside the meat where they belong.

Slicing bavette correctly makes a noticeable difference. Cut with the grain first to divide the steak into manageable sections. Then turn each section and slice against the grain into thin strips. That direction gives you tender, clean slices rather than chewy ones. A sprinkle of sea salt flakes over the sliced steak finishes it well.

The garlic yoghurt sauce is simple and effective. Greek yoghurt keeps it thick and creamy. Minced garlic gives it a sharp, savory edge. Finely chopped chives add freshness without taking over. A squeeze of lemon juice lifts the whole sauce. If you prefer a firmer consistency, use lemon zest instead. It gives the same citrus brightness without adding liquid, so the yoghurt stays thick enough to spoon cleanly alongside the steak.

The crispy potatoes complete the plate. Parboiling them first for 15 minutes is what makes the difference. The surface roughens slightly when drained, giving the oil something to grip. Seasoned with paprika powder, salt, and black pepper, they cook in a frying pan for about 20 minutes, turned occasionally, until golden on the outside. The paprika adds a warm color and a mild smoky note that sits well next to the garlic and yoghurt.

Together, the pan-seared flap steak, garlic yoghurt, and crispy potatoes make for an affordable and satisfying dinner. The cut is accessible, the technique is straightforward, and the plate needs nothing else. It works well as a relaxed weeknight meal and just as well as a proper date night dinner for two.

This recipe used a similar pan-seared technique as our Flat Iron Steak recipe, which is worth trying if your butcher ran out of flap steak.
