Ingredients for Making Flank Steak
- Butter: I recommend using unsalted butter to control the salt levels better.
- Fresh Herbs: While I used parsley and basil, you can use your favorite fresh herbs. Rosemary and thyme are great options.
- Lemon Juice: Freshly squeezed lemon juice is best.
- Salt and Pepper: Adjust the salt to your liking.
- Flank Steak: In this recipe, anything between 1 ½ to 2 ½ pounds will work.
- Oil: I like avocado oil for high heat cooking, but you can use your favorite heat-safe oil. If you use olive oil, ensure that it is not extra-virgin due to the low smoke point.
- Soy Sauce: If you are gluten-free, use either gluten-free tamari or coconut aminos. Coconut aminos are the best option if you are keto.
- Seasonings: Garlic powder, oregano, and salt add just the right punch of flavor to this flank steak recipe.
Tips & Tricks
- Use an instant-read meat thermometer to ensure that the flank steak is cooked to your liking.
- If you are cooking flank steak on the Blackstone griddle, I recommend using an infrared thermometer to ensure that the griddle is at the proper temperature.
Frequently Asked Questions
Flank steak is a lean, flavorful cut of beef that is ideal for grilling, griddling, or pan-frying.
The steak comes from the cow's flank, or lower abdominal area, and is usually fairly lean but does have some marbling of fat. This fat gives the steak its rich flavor and also helps to keep it moist during cooking.
One option is skirt steak. Skirt steak is thinner than flank steak, so it tends to cook more quickly. It also has a bit more fat, which means it's extra juicy and flavorful.
Plus, skirt steak is typically less expensive than flank steak, so it's a great option if you're on a budget.
Another good alternative is hanger steak. Hanger steak is often overlooked, but it's very similar to flank steak in flavor and texture.
The main difference is that hanger steak is tougher, so it's best to marinate it for several hours before cooking. But if you do that, you'll be rewarded with a juicy, delicious steak full of flavor.
Sirloin, New York strip steaks, ribeye, and filet mignon are all good alternatives to flank steak.
There are a few things to keep in mind regarding how to make tender flank steak.
First, you should marinate flank steak before cooking to add flavor and help to tenderize the steak.
The best way to cook this cut is to grill it, griddle it, or cook flank steak on the stove over medium-high to high heat. This will help to sear in the natural juices, and it will also create a flavorful crust on the outside of the meat.
Lastly, ensure that you do not overcook flank steak. Most people agree that this steak cut is best served medium-rare.
