Flat Iron Steak with Red Wine Sauce Recipe by Best Online Steaks

2 (1 lb.) flat iron steaks 

6 tbsp cold unsalted butter 

3-4 tbsp extra-virgin olive oil 

1 tbsp minced garlic 

1 tsp dried oregano 

1/4 cup tomato paste 

1 onion, thinly sliced (red or yellow) 

1 tsp paprika (smoked is an excellent option), plus more to taste 

Salt and fresh ground black pepper to taste 

1. Get the grill started on medium-high heat. Once hot salt and pepper the steaks then drizzle with approximately 3 tablespoons of olive oil. Grill the steaks to your favorite temperature. About 5 minutes per side should bring you to medium-rare.

2. Remove the steaks from the heat to a cutting board and cover with a foil tent. Rest for 10 minutes. 

3. While the steak is resting, in a heavy saucepan melt 2 tablespoons of butter over medium-high heat.

4. Add and sauté the onions for approximately 5 minutes or until they are tender.

5. Season to taste with salt and add in the oregano and garlic continuing to sauté another 30 seconds. 

6. Add in the tomato paste and continuously stir for 2 minutes. Whisk in the cup of wine and simmer occasionally stirring for about 10 minutes or until the sauce reduces by half.

7. Strain the sauce into a small bowl ensuring your press through as much liquid from the solids as possible. Put just the liquid back into the pan and bring to a slow simmer

8. Cut the butter into small chunks of approximately 1/2-inch each and whisk into the sauce a few at a time.

9. Add salt and pepper to taste. 

10. Slice the steaks thinly and across the grain. Plate the desired number of pieces and drizzle the sauce over the steak along with a drizzle of olive oil on each.

You are ready to serve.
