A fresh and seasonal method to enhance the sweetness and complexity of flank steak? We suggest preparing an additional batch of the tomato vinaigrette and storing it in the refrigerator. It is ideal for fish, poultry, or even spaghetti.

Flank steak was a staple in my upbringing, maybe our most frequently consumed red meat. The flavor is delightful, however quite lean; hence, I considered this dish an effective means to introduce richness and achieve balance with a sweet and acidic tomato sauce. Roasting the cherry tomatoes and shallots enhances their sweetness, which balances the acidity of the sherry vinegar in the sauce. The tomato vinaigrette complements any grilled meat, and I also serve the flank steak atop truffled polenta or mashed potatoes. This recipe yields sufficient vinaigrette for a steak exceeding 1 to 2 pounds.
Ingredients
For the cherry tomato vinaigrette
1 pint of cherry tomatoes
Two large shallots, cut.
1 tablespoon of extra-virgin olive oil
Two tablespoons of sherry vinegar
Two clove of garlic, finely minced.
One egg yolk
1/2 teaspoon of kosher salt
1/2 teaspoon of pepper
1/2 cup of extra-virgin olive oil
One teaspoon of Dijon mustard
For the flank steak
one 1 to 2 pound grass-fed flank steak
Two tablespoons of balsamic vinegar
Two cloves of garlic, finely chopped.
Two tablespoons of honey
Two tablespoons of Worcestershire sauce
1 tablespoon of Dijon mustard
1/2 cup of extra-virgin olive oil
Instructions
For the cherry tomato vinaigrette.
Preheat the oven to 425 degrees Fahrenheit. Arrange the tomatoes, shallots, and 1 tablespoon of oil on a baking sheet. Season with salt and pepper, mix thoroughly, and separate the small shallot rings.
Roast for approximately 10 minutes. Rotate, activate the broiler, and cook for an additional 1 to 2 minutes, or until the tomatoes blister and rupture. Allow it to cool.
Combine the egg yolk, garlic, Dijon mustard, vinegar, salt, and pepper. Incorporate the olive oil using a whisk.
Once the tomato-shallot mixture has cooled from hot to warm, combine it with the vinaigrette. It will become marginally denser.
Frank steak
Combine balsamic vinegar, one clove of garlic, honey, Worcestershire sauce, Dijon mustard, and half a cup of olive oil in a plastic bag. Include flank steak. Allow to marinate for 4 to 6 hours in the refrigerator.
Preheat the grill to medium-high temperature. Grill the steak for 4 to 5 minutes on each side to achieve medium rare doneness. Allow to rest for 10 minutes, then slice the steak thinly across the grain.
Present the steak piece atop polenta or potatoes, with the tomato sauce drizzled over it.
