This is no ordinary Stuffed Flank Steak, it is oozing with flavor! First, you get mushrooms, onions, and garlic sauteed together. Then they are mixed with fresh parsley and basil, then parmesan, and goat cheese! Roll it all up in Flank Steak and roast for an amazing dinner.
Rough chop the parsley and Basil. Finely dice the onion. Mince the garlic.
If whole, quarter or rough chop the mushrooms and add in batches to a mini food processor or all to a large processor. Pulse until rice or pea size.
To a preheated large skillet, add the onions and cook for 4-5 minutes, stirring so that they don't burn.
Then add the mushrooms, salt, and pepper. Stir to combine and cook down until all liquid that comes from the mushrooms cooks off and the mixture starts to turn a darker color. Remove from heat and let cool.
Once the mushroom mixture is cooled, add the garlic, parmesan cheese, parsley, basil, crumbled goat cheese, and egg white. Mix thoroughly.
Lay the flank steak out flat and rub both sides of the meat with extra virgin olive oil, salt, and pepper.
Next, spread the mushroom cheese stuffing over the steak in an even layer, but not covering the very end where you will start rolling.
Starting at the end without the stuffing, roll the flank steak over the stuffing as tight as possible without squeezing all of the filling out the sides.
Continue rolling gently until completely rolled. Then using 3 pieces of cooking string, tie the flank steak roll tight, but not so tight that the stuffing squeezes out the sides. If any does come out, just push it back in.
Line a shallow baking sheet with aluminum foil and then transfer the flank steak to the pan. Trim the string ties as needed.
Place the flank steak on the center rack in the oven and turn the broiler on high for 10 minutes. Then turn the oven to bake 350 F degrees and roast for 30 minutes. Finally after the 30 minutes is up, turn the oven down to 300 and roast for a final 10 minutes. (Total cooking time = 50 minutes for medium rare).
Remove the flank steak from the oven and wrap the aluminum foil around it to cover. Let sit for 10 minutes so the juices can settle back into the meat and it finishes cooking and stays nice and moist.
Slice, serve, and enjoy!
You can get about five 1-inch slices from the flank steak roll, which is about 4-5 servings.
