🥘 Ingredients

*Be sure to see the recipe card below for ingredients, amounts & instructions!*
Flat Iron Steak
- Olive Oil – This will help to sear your steak without any burning! I like to use a standard olive oil or a neutral oil with a high smoke point.
- Flat Iron Steak – Flat iron steak is so versatile and has a delicious marbling that keeps the steaks juicy! You’ll want ½ pound of steak per person.
- Salt & Pepper – Since we’re using a marinade for this steak, we’ll keep the seasoning simple!
- Butter – You’ll add butter to the steak at the end to baste it and coat it in amazing buttery flavor!
Red Wine Marinade
- Dry Red Wine -- Red wine tenderizes the steak and adds a ton of flavor! Steak and wine are a perfect pair, so the flavor is amazing in a marinade (See Tips & Recipe Notes)
- Olive Oil – I like to use extra virgin olive oil (EVOO)here for the flavor and because it’ll help to seal in the juices of the steak.
- Lemon Juice – Fresh lemon juice also helps to tenderize the meat and adds great flavor!
- Minced Garlic – I love the perfect flavor combination of garlic and steak! You can use pre-minced or mince your own?
- Onion Powder – This will add more fantastic flavor to the steaks! You can use onion powder or granulated onion, but not onion salt.
- Sea Salt – Salt is of course necessary when making steak! We want to make sure that the steaks are perfectly seasoned, and the delicious natural flavors are highlighted.
- Black Pepper – I love freshly ground black pepper here to enhance the marinade and the flavors of the steak!
📖 Variations
- Want to add even more flavor to your steaks? You can add some chopped fresh herbs like rosemary or thyme to the steak marinade to make them even more delicious!
- Can’t have red wine, but want to make these amazing steaks? Try using half the amount of pomegranate juice! It has that rich, fruity flavor without the alcohol! It is much sweeter, however—so you should use less! You could also try substituting beef broth with a little red wine vinegar!
🔪 Step-by-Step Instructions
Making an amazing steak has never been easier! The marinade is so simple but so delicious!
Flat Iron Steak Marinade
- Make the Marinade. In a mixing bowl, combine ½ cup dry red wine, ¼ cup of extra virgin olive oil, 1 tablespoon of lemon juice, ½ tablespoon of minced garlic, ½ tablespoon of onion powder, 1 teaspoon of sea salt and 1 teaspoon of ground black pepper. Then, pour the marinade into a Ziploc plastic storage bag.
- Add the Steaks. Add 1 pound of flat iron steaks into the plastic storage bag, press out the extra air, and seal the bag. Marinate in your refrigerator for at least 4 hours, or overnight.
Searing the Flat Iron Steaks
1 2
- Remove Steaks from Marinade. Remove the bagged steaks from the fridge, take out of marinade and then pat dry with a paper towel to remove excess marinade. Allow the steaks to come to room temperature for no more than 1 hour before searing.
- Prep the Pan. In a large skillet or cast-iron pan, heat ½ tablespoon of olive oil over medium high heat. You want the pan to be very hot, and the oil to be shimmering.
- Sear the Steaks. Sprinkle the now room temperature steaks with salt and pepper to taste and add the steaks to the pan. Sear your steaks for 4 to 6 minutes on one side, then turn over and sear for another 3 to 5 minutes until the steaks have reached the desired level of doneness (use an instant-read thermometer to make sure it’s at the perfect temperature).
- Baste with Butter. When the steaks are 2 minutes away from being done, add 1 tablespoon of butter to the pan. Let it melt, then quickly spoon the butter over the steaks to baste them and help the brown further.
- Serve! Remove the steaks from the pan and allow to rest for 5 minutes before serving.
My easy and delicious red-wine marinated Pan Seared Flat Iron Steaks are an incredible main course! They’re perfect for dinner served with hearty sides like mashed potatoes, or even for lunch sliced over a salad with lots of mixed veggies. Enjoy!
💭 Tips & Recipe Notes
I like to use a dry red wine for the marinade – make sure it’s something you’ll drink!
- I recommend using a Cabernet Sauvignon, or another medium-bodied red wine for the marinade that you’d like to drink with the meal.
Ensure a perfect sear by making your pan and oil very hot!
- The pan should be shimmering and very hot when you add the steaks, so that they create a beautiful golden-brown sear on the steaks.
Use an instant-read thermometer probe to make sure your steak comes to your desired temperature!
- Bring the steaks to an internal temperature of 120-125°F (49-52°C) for rare, 125-129°F (52-54°C) for medium rare, 130-139°F (54-59°C) for medium or 140-145°F (60-63°C) for medium well.
- The carryover cooking while the steaks are resting will finish bringing them up to temperature completely!
Make sure to let the steaks rest for at least 5 minutes before serving or slicing into them!
- Dry steaks are never good! If the steaks are allowed to rest, the juices will be able to evenly distribute back into the meat and will keep the steak wonderfully juicy!
🥡 Storing & Reheating
You’ll want to make sure any leftover steak is well-wrapped in plastic cling film or aluminum foil and then it can go in your fridge, where it’ll keep for up to 3 to 4 days!
Did you know you can freeze steaks? Just make sure to put it into a good freezer storage bag, squeeze out the extra air, label, and it’s good to keep it in your freezer for up to 6 months. When ready to reheat, defrost in the refrigerator overnight.
Reheating Pan Seared Flat Iron Steaks
My favorite steak reheat method is to use the oven! Start by preheating your oven to 250°F (121°C). Then place steaks on a baking sheet (use a wire rack if you have it) and bake for about 30 minutes or until the center reaches at least 125°F (52°C).
If desired, you can also sear the leftover steak quickly in a hot skillet to re-brown.
🥩 What To Serve With Flat Iron Steak
❓ FAQ
Basting steaks with butter is a not-so-new food trend, and is a French technique called 'arroser'—and it’s popular for good reason! Butter is of course super flavorful, and it deepens the crust on the outside.
Butter also can help the steak finish cooking more quickly by applying heat to both sides of the steak.
The flat iron steak is a cut that comes from the chuck of the cow! This affordable and delicious cut is marbled nicely with fat, so it keeps the meat tender and moist. It’s also sometimes referred to as a top blade steak!
