Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

2 filet mignons
Salt and ground black pepper, to taste (season generously)
1 tablespoon oil
2 tablespoons unsalted butter
5 cloves garlic, peeled
4 sprigs fresh rosemary

Directions

Remove the filet mignons from the refrigerator 30 to 60 minutes before cooking. Unwrap, season generously with salt and black pepper, and let them rest on a plate at room temperature.
Preheat the oven to 360°F. Place a medium cast iron skillet over high heat for 3 to 5 minutes until very hot.
Add the oil carefully to the hot skillet. Sear the filet mignons for 2 to 3 minutes per side (or 1 to 2 minutes for smaller cuts) until a rich brown crust forms. Remove the skillet from heat.
Add the butter, garlic, and rosemary to the skillet. Transfer the skillet to the oven and bake for 2 to 8 minutes depending on your desired doneness.
Remove the steaks from the oven when the internal temperature is about 5 to 10°F below your target doneness. As a general guide:
- 2 minutes for rare
- 3 to 4 minutes for medium-rare
- 5 minutes for medium
- 6 to 7 minutes for medium-well
- 8 minutes for well-done
Transfer the steaks to a plate, tent loosely with foil, and let rest for 5 to 10 minutes before serving. Spoon the garlic butter and softened garlic cloves over the top.

Variations

You can customize this filet mignon recipe in several ways. Add thyme instead of rosemary for a slightly different herbal note. For a richer finish, include a splash of heavy cream or a spoonful of Dijon mustard to the pan sauce. You can also top the steak with blue cheese or a pat of compound butter for added indulgence. If you prefer a smoky flavor, finish the steak on a grill instead of in the oven.

Storage/Reheating

Store leftover filet mignon in an airtight container in the refrigerator for up to 3 days. To reheat, place the steak in a low oven at about 275°F until warmed through. Avoid microwaving if possible, as it can overcook the meat and make it tough. Leftovers can also be sliced thin and used in sandwiches, salads, or wraps.

FAQs

What cut of meat is filet mignon?

Filet mignon is cut from the tenderloin, which is one of the most tender parts of the cow.

Why should I bring the steak to room temperature first?

This helps the steak cook more evenly, resulting in a better texture and more consistent doneness.

Do I need a cast iron skillet?

A cast iron skillet is ideal because it retains heat well, but any heavy oven-safe pan will work.

How do I get a good crust on the steak?

Make sure the pan is very hot and avoid moving the steak too much while it sears.

Can I use dried rosemary instead of fresh?

Yes, but fresh rosemary provides a more aromatic and vibrant flavor.

How do I check the doneness of the steak?

Using a meat thermometer is the most reliable method to achieve your preferred doneness.

Why do I rest the steak after cooking?

Resting allows the juices to redistribute throughout the meat, keeping it juicy and tender.

Can I cook this without an oven?

Yes, you can continue cooking on the stovetop by lowering the heat and basting with butter until done.

What oil is best for searing steak?

Use a high smoke point oil such as vegetable oil, canola oil, or avocado oil.

Can I add more seasoning?

Absolutely, you can add spices like paprika, garlic powder, or even a steak seasoning blend for extra flavor.

Conclusion

Perfect filet mignon is all about technique and simplicity. With a hot sear, a gentle oven finish, and a proper resting period, you can achieve a tender, flavorful steak that rivals any restaurant. This recipe makes it easy to cook an impressive meal that feels special every time.
