Heat a grill pan over high heat. Sprinkle steak evenly with salt and pepper. Lightly coat the steak with cooking spray. Add steak to pan; grill for 5 minutes on each side or until desired degree of doneness. Let stand 3 minutes.
Heat a small skillet over medium-high heat. Add oil to pan; swirl to coat. Add garlic; cook for 30 seconds or until fragrant. Add soy sauce, mustard, and sugar; cook 1 minute or until bubbly. Remove pan from heat. Stir in cream and 1 tablespoon cilantro. Cut steak diagonally across grain into thin slices. Sprinkle with remaining 1 tablespoon cilantro. Serve sauce with steak.
We seldom eat flank steak as it can be tough, but this recipe, along with an overnight marinade, kept that from happening. I marinated the flank steak in red wine and soy sauce (using a marinade from this site) overnight, dried it thoroughly so that it would sear properly, and grilled it 5 minutes a side in a heated grill pan. It was perfectly pink in the middle, cut easily and was tender and tasty. The soy/mustard sauce was delicious (I doubled the recipe) and easy to make in advance, adding the cream at the last minute. The whole family raved. I'm sure leftovers (my flank steak was 1.6 lbs- there is no such thing as a 1-lb flank steak) would have been great, but there weren't any! Highly recommended.
The sauce was amazing. I would definitely double it next time! The only change I made was to replace the heavy whipping cream with 1/2&1/2. Grilled the flank steak on the barbecue rather than the stove. Will be making this one again.
this recipe is wonderful! It pleased not only my teenagers, my eleven year old son, and my husband. Which is nearly impossible. Just absolutely a cinch to make and just delicious. I grilled it and served with mashed potatoes and balsamic roasted vegetables.
Pleasantly surprised by this! As mentioned, It is salty. Between the soy and dijon and the added on the steak, it can get salty. We used low sodium too. Paired it with roasted potatoes, red bell pepper and onion and a Caesar salad. (another salt bomb) Had sour cream on the roasted veggies and it was awesome mixed with the sauce (we doubled the sauce). Licked our plates. Will not add the salt to the steak next time. Yes! There will be a next time. And soon. try it.
Absolutely wonderful and easy! Pay attention to the reviews that stress using low-sodium soy sauce. I love salty things but this was too salty, even for me, with full salt soy sauce. Not too mustardy as I was afraid it would be. I would not recommend "garlicky asparagus" and "garlic mashed potatoes." Enough is enough. I served it with broccoli with toasted pine nuts with red pepper flakes and lemon, and corn on the cob.
