What type of food is flat iron steak, and what does flat iron steak taste like?

Flat iron steak is a cut of beef from the shoulder blade area of the steer. It was originally referred to as “butler’s-steak” because it was the cut that butchers would keep for themselves since it was more tender and flavorful than other cuts.

When cooked correctly, flat iron steak has an intensely beefy flavor with a tender texture. Its well-marbled nature means that it has plenty of flavors even when cooked medium or medium rare.

The steak can be pan-seared, grilled, broiled or roasted — all methods work great.

When you serve it with a side dish such as mashed potatoes or baked beans, this succulent steak is sure to please any palate!

FAQs on what to serve with flat iron steak

Q1. What’s the best way to cook a flat iron steak?

For the perfect flat iron steak, it’s best to start with a high-quality cut of meat. Make sure that your steak is dry and at room temperature before cooking.

To prepare the steak, season generously with coarse salt and freshly ground black pepper on both sides. If desired, you can also add other herbs or spices for flavor.

Heat a large skillet over a medium-high flame and coat the bottom of the pan lightly with oil. Place steaks in a hot skillet and cook for 3 minutes without moving them or flipping them.

Turn steaks over to the other side and continue cooking for another 2 minutes for medium-rare doneness (or however long you prefer). Once cooked, remove from heat and let rest for 5 minutes before slicing.

Q2. Can you casserole flat iron steak? 

Yes, you can! A flat iron steak casserole is a great way to enjoy the tenderness and flavor of this cut of beef. You can easily make a delicious meal with minimal effort. Start by marinating the steak in olive oil, garlic, herbs, and seasonings.

Then sauté onions and peppers in a skillet until they are soft. Place the steak and vegetables into a greased baking dish, then add your favorite sauce or gravy.

Bake for 25-30 minutes at 375 degrees Fahrenheit or until the internal temperature reaches 145 degrees Fahrenheit. Let it rest before slicing and serving it with your choice of sides, like mashed potatoes or roasted vegetables. Enjoy!

Q3. How many times do you flip flat iron steak?

Flat iron steak is a relatively thick cut, so it should be flipped at least two to three times during cooking. This will ensure that both sides cook evenly and reach the desired texture and temperature. If possible, use a meat thermometer to check for doneness as well.

The internal temperature of flat iron steak should reach 145°F (63°C) for medium-rare and 160°F (71°C) for medium-well. Cooked properly, flat iron steak can be a delicious addition to any meal! Enjoy!

Q4. How much flat iron steak per person?

The amount of flat iron steak per person will vary depending on the size of the serving and whether it is being served as an entree or part of a larger meal. Generally, four to six ounces of steak per person is recommended when preparing a flat iron steak entree. When including the steak as part of a larger meal, two to three ounces per person may be sufficient.

When purchasing your flat iron steaks, make sure to factor in that each one has about 25 percent shrinkage after cooking due to loss of moisture and fat. To ensure you have enough for everyone at your gathering, it’s best to purchase 1/4 pound more than what you anticipate needing. Enjoy!
