If you want to know what temp do you cook filet mignon in oven, the short answer is 400°F. Filet mignon in the oven typically starts with a stovetop sear, then finishes at 400°F until it hits your target doneness.
This method gives you a dark crust outside and a tender, juicy center. It works every time once you know the right numbers.
What Temp Do You Cook Filet Mignon In Oven
The oven temperature for filet mignon is 400°F. That heat is high enough to finish the meat quickly without drying it out.
Filet mignon is a lean cut. It has very little fat, so it can dry out fast if you cook it low and slow or leave it in too long. A hot oven solves that problem.
You sear the steak in a skillet first. Then you move the whole pan into the oven. The steak finishes in about 5 to 8 minutes, depending on thickness and how done you want it.
Why 400°F Is The Right Oven Temp
Here is why this number works so well:
- It creates a strong finish without overcooking the outside.
- It keeps the inside tender because the cooking time is short.
- It matches the searing heat from the stovetop, so the crust stays crisp.
- It works for both thick and thin cuts with small time adjustments.
Some recipes call for 425°F or 450°F. Those temps work too, but they leave less room for error. At 400°F you get a bit more control, and thats helpful when you are still learning your oven.
Target Internal Temperatures For Each Doneness Level
The oven temp is only half the story. The real test is the internal temperature of the meat. Use a meat thermometer every time.
- Rare: 120°F to 125°F
- Medium rare: 130°F to 135°F
- Medium: 140°F to 145°F
- Medium well: 150°F to 155°F
- Well done: 160°F and above
Pull the steak out of the oven about 5°F before it reaches your target. The temperature will keep rising as the meat rests. This is called carryover cooking, and it is a real thing.
Step By Step: How To Cook Filet Mignon In The Oven
Follow these steps in order. The whole process takes about 20 minutes from start to finish.
- Take the steaks out of the fridge 30 to 40 minutes before cooking. Room temp meat cooks more even.
- Pat the steaks dry with a paper towel. Dry meat sears better.
- Season both sides with salt and black pepper. Be generous with the salt.
- Preheat your oven to 400°F. Place a rack in the middle position.
- Heat a cast iron skillet or oven safe pan over high heat on the stove. Add a tablespoon of oil with a high smoke point.
- Wait until the oil just starts to shimmer. Then place the steaks in the pan.
- Sear for 2 to 3 minutes per side without moving them. You want a deep brown crust.
- Add a knob of butter, a garlic clove, and a sprig of thyme if you like. Spoon the melted butter over the steaks.
- Move the whole pan into the oven. Do not cover it.
- Cook for 5 to 8 minutes. Start checking with your thermometer at the 4 minute mark.
- Pull the steaks when they are 5°F below your target temp.
- Rest them on a cutting board or plate for 5 to 10 minutes. Loose tent with foil if you want, but do not wrap tight.
- Slice against the grain and serve.
How Long To Cook Filet Mignon At 400°F
Time depends on thickness. Here is a simple guide for a 1.5 to 2 inch thick steak after searing:
- Rare: 4 to 5 minutes
- Medium rare: 5 to 6 minutes
- Medium: 6 to 7 minutes
- Medium well: 7 to 8 minutes
- Well done: 9 to 10 minutes
Thinner steaks, around 1 inch, need less time. Check them at 3 minutes. Thicker steaks over 2 inches may need a couple extra minutes. Always trust your thermometer over the clock.
Common Mistakes To Avoid
These small errors can ruin an expensive cut of beef:
- Starting with a cold steak. It cooks uneven.
- Wet meat going into the pan. It steams instead of sears.
- A cold pan. The crust will not form right.
- Walking away during the sear. Two minutes goes by fast.
- Skipping the rest. Cutting early lets all the juice run out.
- Using a dull thermometer or not using one at all.
Tools That Make This Easier
You do not need much, but a few items help a lot:
- An instant read meat thermometer. This is the most important tool.
- A cast iron skillet or heavy oven safe pan.
- Tongs for flipping.
- A cutting board with a groove to catch juices.
Can You Cook Filet Mignon In The Oven Without Searing
Yes, you can. Some people skip the stovetop step and roast the steak at 400°F the whole way. It still tastes good, but the crust will be softer and less flavorful.
If you go this route, roast for about 12 to 15 minutes for medium rare, depending on thickness. Rub the steak with oil and seasoning first. Then check the temp early and often.
The sear adds flavor and texture. It is worth the extra few minutes if you have the time.
Resting And Serving Tips
Resting is not optional. Give the steak at least 5 minutes. Ten is better for thick cuts.
Slice against the grain. For filet mignon the grain is subtle, but you can still spot the lines. Cutting the right way keeps each bite tender.
Serve with simple sides. Roasted potatoes, green beans, or a light salad all work well. Save the pan drippings to spoon over the top.
Now you know the answer. Set your oven to 400°F, sear first, and pull the steak at the right internal temp. Thats the whole game.
