Make the Rub for the Flank steak, by adding all ingredients to a small mixing bowl, then stir to combine. Store in a plastic storage container or baggie.
You can marinate the steak in the rub overnight or do this step right before cooking. If you want to do this the day before, then drizzle a tsp or so of the olive oil on the steak and rub all the seasoning mixture all over the steak on both sides. Place in a storage container, seal it, and store in the fridge.
Clean the broccoli and cut off 5 cups of florets and top of the stems. I love to use the stems in addition to the florets as they are just as flavorful and have lots of nutrition so why waste them?
You can cut the potatoes a day in advance and store in water in the fridge, but I would not do this more than 1 day ahead. You want to quarter the potatoes to roughly all the same size.
Mince the garlic. Add the Sour Cream, garlic, and chives to a mini food processor. Pulse to blend until the chives are completely blended. Season with salt and pepper to taste. Store in a sealed container in the fridge.
Preheat the oven to 400F degrees. If you stored the cut potatoes in water, drain them and pat them dry with a clean towel.
To a large Sheet pan, add the broccoli and potatoes. Drizzle or Spray with Olive Oil. Go light with the oil and then rub it all around with your hands. Sprinkle with salt and pepper and again rub it all over. Spread out into a single layer.
Place the vegetables in the preheated oven and roast them for 20 minutes.
If you marinated the steak in the rub overnight, pull it out and let it rest at room temperature while the veggies cook. If you did not, then drizzle a tsp or so of the olive oil on the steak and rub all the seasoning mixture all over the steak now on both sides and set aside.
After 20 minutes in the oven, pull the veggies out and using a spatula, push them all out to the outside of the pan, making space in the center for the steak. Place the rubbed steak in the center and put the pan back in the oven for 10 minutes.
After 10 minutes, change the oven setting to broil, move the pan up to the top broiler shelf and cook under the broiler for 5-7 minutes. At 3 minutes, check to make sure the potatoes and broccoli are not burning and if they are, move the pan down a shelf.
Once the steak is done cooking, let the pan sit out at room temperature for 10 minutes to allow the meat to finish cooking and the juices to redistribute. If you cut the meat too soon, all of the good juices will be let out and the meat may be dry.
Serve with the Garlic Chive Crema and Enjoy!
