• Worcestershire Sauce
• Soy Sauce
• Olive Oil
• Mustard - I used Dijon

Directions for Marinade

Combine everything together in a large bowl, stir to combine using a stainless steel whisk. I like to use my glass batter bowl that comes with a lid.

Once everything is combined, you can taste the marinade to see if you need to add salt, however, the salt in the soy sauce should be enough.

Add the steak to a casserole dish with lid. If your's doesn't have a lid, you can cover with plastic wrap. Pour the marinade on top, cover the casserole dish and refrigerate for at least 2 hours.

How long can you marinate steak in the refrigerator?

According to the USDA, you can safely leave marinated steak in the refrigerator for up to 3 days, however, I have never done that and really don't recommend it. If you leave steak marinading for too long, it can change the texture and even flavor.

How to Cook Steak in a Cast Iron Grill Pan

Remove the steak from the refrigerator and let it sit on the counter, covered, for at least 30 minutes so it comes to room temperature.

Over medium-high heat, add a tablespoon of oil to the bottom of a heavy cast iron skillet or grill pan. Allow the pan to preheat for about two to three minutes.

Remove the steaks from the marinade and lightly dab them dry using a paper towel. You don't want the steaks to boil in the marinade as they cook.

Allow the steaks to cook for one to two minutes before gently flipping. After another minute or two of cooking on top of the stove, place the cast iron grill pan in a preheated 450 degree oven.

Continue cooking until the desired degree of doneness. You can check out the chart below for guidelines and use a Digital Meat Thermometer to check the internal temperature. Remove the steaks from the grill pan as they will continue to cook!

Place the cooked steaks on a warm platter or cutting board. Cover loosely with aluminum foil for about 10 minutes before slicing and serving. If you cut into the steaks now, the juices will run out all over the cutting board. Be patient and wait.

How do I know when Steak is done?

This has always been a challenge for me until I purchased my digital meat thermometer. Follow this chart below when cooking steak to your favorite desired temperature:

• Rare: 125 degrees
• Medium Rare: 135 degrees
• Medium Well: 150 degrees
• Well Done: 160 degrees

Tips for Cooking in Cast Iron Skillet

• Have the steaks at room temperature before cooking.
