How To Cook Filet Mignon In The Oven

ByLily

Oven-roasting filet mignon produces even cooking throughout, particularly when you sear it first and finish it at moderate heat. If you want to know how to cook filet mignon in the oven, the method below keeps the meat tender and juicy every time.

Filet mignon is a lean cut, so it dries out fast if you overdo it. The trick is a hot sear for color, then a gentle oven finish to your target temperature.

This guide covers prep, seasoning, searing, roasting, resting, and the temperatures that matter most.

What You Need Before You Start

Gather your tools and ingredients first. That way the cooking moves fast and nothing burns while you search for a pan.

  • Two filet mignon steaks, about 6 to 8 ounces each, 1.5 to 2 inches thick
  • Kosher salt and coarse black pepper
  • 1 tablespoon of high-smoke oil, such as canola or grapeseed
  • 1 tablespoon of butter, plus optional garlic and thyme
  • Oven-safe skillet, cast iron works best
  • Instant-read meat thermometer
  • Aluminum foil and a cutting board for resting

Let the steaks sit at room temperature for 30 to 40 minutes. Cold meat cooks unevenly in the center.

How To Cook Filet Mignon In The Oven

Follow these steps in order. The whole process takes about 20 to 25 minutes from a hot pan to a rested steak.

Step 1: Preheat The Oven And Dry The Meat

Set your oven to 400 degrees Fahrenheit. Pat the steaks completely dry with paper towels. Moisture on the surface steams the meat instead of browning it.

Step 2: Season Generously

Sprinkle salt and pepper on all sides. Use more salt than feels normal, since a thick cut needs it. Let the seasoned steaks rest for 10 minutes while the oven finishes heating.

Step 3: Sear In A Hot Skillet

Heat the oil in your skillet over medium-high heat until it shimmers. Place the steaks in the pan away from you to avoid splatter.

  1. Sear for 2 minutes without moving them.
  2. Flip and sear the other side for 2 minutes.
  3. Hold each steak with tongs and press the edges down for 15 seconds per side.
  4. Add butter, garlic, and thyme, then spoon the melted butter over the tops.

You want a deep brown crust, not a burnt one. Lower the heat slightly if the pan starts smoking hard.

Step 4: Move The Skillet To The Oven

Transfer the whole oven-safe skillet to the middle rack. Roast for 4 to 6 minutes for medium-rare, depending on thickness.

Start checking at 4 minutes. A thermometer is the only reliable way to judge doneness.

Step 5: Pull At The Right Temperature

Remove the steaks when they hit 5 degrees below your target. Carryover cooking raises the internal temp while they rest.

  • Rare: pull at 120 F, finish at 125 F
  • Medium-rare: pull at 130 F, finish at 135 F
  • Medium: pull at 140 F, finish at 145 F
  • Medium-well: pull at 150 F, finish at 155 F

Medium-rare is the sweet spot for filet mignon. Going past medium dries out this lean cut quickly.

Step 6: Rest Before Slicing

Place the steaks on a board and tent them loosely with foil. Rest for 5 to 10 minutes. This lets the juices redistribute instead of running onto the plate.

Slice against the grain if you cut them at all. Many people serve filet mignon whole.

Common Mistakes To Avoid

Small errors ruin an expensive cut. Watch out for these.

  • Skipping the dry-off step, which prevents a good crust
  • Cooking from cold, which causes a raw center and gray band
  • Using olive oil at high heat, since it burns and turns bitter
  • Trusting time over a thermometer
  • Cutting too early and losing all the juice

If your steaks are thinner than 1.5 inches, shorten the oven time to 3 to 4 minutes. Thicker cuts may need 7 to 8 minutes.

Pan Sauce And Serving Ideas

The skillet holds a lot of flavor after roasting. Pour off most of the fat, then add a splash of beef broth or red wine over medium heat.

Scrape the browned bits, simmer for 2 minutes, and stir in a small piece of cold butter. Spoon it over the steaks.

Serve with roasted potatoes, green beans, or a simple salad. Keep the sides light so the steak stays the focus.

Make-Ahead And Reheating Tips

You can sear the steaks up to a day ahead and chill them. Finish in a 400 F oven for 6 to 8 minutes when guests arrive.

To reheat leftovers, warm them gently at 250 F for 8 to 10 minutes. High heat toughens the meat a second time.

Raw seasoned steaks keep in the fridge for up to 24 hours. Bring them back to room temp before cooking.

Final Thoughts

Oven roasting gives you control and consistency, which matters with a cut this pricey. Sear hard, roast gently, and pull early.

With a thermometer and a short rest, you will get a tender, evenly pink filet mignon every single time you make it.
