Choosing The Right Filet Mignon
Filet mignon is a tender and lean cut of beef. Choosing the right piece affects taste and cooking time.
For a 6 oz filet mignon cooked in a cast iron pan without an oven, select a cut that cooks evenly.
Selecting A Quality Cut
Look for a filet mignon with a bright red color and fine texture. Avoid cuts with brown spots or dryness.
Choose a steak about 1.5 to 2 inches thick. This thickness cooks well in a cast iron pan without drying out.
- Bright red color means fresh meat
- Fine grain texture is more tender
- Even thickness helps with uniform cooking
- Fat marbling adds flavor and juiciness
Preparing The Steak
Remove the filet mignon from the fridge 30 minutes before cooking. This helps it cook evenly.
Pat the steak dry with paper towels. Season both sides with salt and pepper for simple flavor.
- Let steak reach room temperature
- Dry surface improves searing
- Use coarse salt and fresh pepper
- Season just before cooking

Preparing Your Cast Iron Skillet
Cooking a 6 oz filet mignon in a cast iron skillet without an oven needs the right prep. Getting the skillet ready helps you cook evenly and get a good sear.
A well-prepared skillet stops the steak from sticking. It also makes cleaning easier after cooking.
Seasoning The Pan
Seasoning means coating your cast iron with oil and heating it. This process creates a smooth, non-stick surface on the skillet.
Good seasoning improves flavor and protects the pan from rust. You can season your pan at home before cooking your steak.
- Wash the pan with warm water and dry it well.
- Apply a thin layer of vegetable oil or flaxseed oil all over the pan.
- Heat the pan on medium heat for 10 minutes or until it smokes slightly.
- Turn off the heat and let the pan cool before storing.
Preheating Tips
Preheating the cast iron skillet is key to a perfect sear on your filet mignon. It helps cook the steak evenly without sticking.
Start heating the pan on medium heat for 5 to 7 minutes. The pan should be hot but not smoking.
- Test heat by sprinkling a few drops of water on the pan. They should dance and evaporate quickly.
- Use a little oil with a high smoke point, like canola or grapeseed oil.
- Spread the oil evenly and let it heat until it shimmers before adding the steak.
Searing Without An Oven
Cooking a 6 oz filet mignon in a cast iron pan can be done without an oven. Searing the steak properly locks in flavor and juices.
This method focuses on using the stovetop alone to get a perfect crust and tender inside.
Ideal Heat Settings
Set the stove to medium-high heat to start. This heat helps create a good sear without burning the meat.
After the initial sear, lower the heat to medium. This cooks the steak evenly inside without overcooking the outside.
- Start with medium-high heat for searing
- Reduce to medium heat to cook through
- Use a cast iron pan for even heat distribution
Searing Techniques
Dry the steak with paper towels before cooking. This helps get a better crust on the meat.
Place the steak in the hot pan without moving it. Let it cook for about 3-4 minutes on each side.
- Preheat the cast iron pan well
- Pat the steak dry to remove moisture
- Do not move the steak while searing
- Sear each side for 3 to 4 minutes
- Use tongs to flip the steak gently

Importance Of Resting
Resting a filet mignon after cooking is very important. It helps the juices stay inside the meat instead of spilling out.
Resting also makes the steak more tender and flavorful. Let the steak rest for about 5 minutes on a warm plate.
