Filet mignon deserves careful attention to oven temperature since this premium cut can dry out quickly when overheated. So what temperature do you cook filet mignon in the oven? The short answer is 425°F for a hot sear, then often lowered to 350°F, or a steady 350°F to 375°F for the whole cook depending on your method.
This guide walks you through exact oven temps, internal doneness numbers, and simple steps that work every time.
Why Oven Temperature Matters For Filet Mignon
Filet mignon is lean. It has very little fat marbling compared to ribeye or strip steak.
That means it can go from perfect to dry in just a few minutes. The right oven temp protects the meat while still giving you a nice crust and a tender inside.
Too high for too long equals a tough, gray center. Too low equals a pale steak with no browning.
What Temperature Do You Cook Filet Mignon In The Oven
Here are the temps that work best, based on how you like to cook.
- 425°F – Best for searing first, then finishing at a lower heat
- 400°F – Good for a quick roast when you want a brown crust
- 375°F – A balanced temp for even cooking without burning
- 350°F – Best for slow roasting and more control over doneness
- 275°F to 300°F – Reverse sear method, cooked low then seared on the stove
Most home cooks get great results with 425°F for a short sear in the oven, followed by 350°F until the steak hits your target internal temp.
The Two Most Popular Oven Methods
Method 1: Sear Then Finish
- Preheat oven to 425°F.
- Season steaks and let them sit at room temp for 20 to 30 minutes.
- Heat an oven-safe skillet on high with a little oil.
- Sear each side for 1 to 2 minutes.
- Move the skillet to the oven and cook 4 to 6 minutes.
- Check internal temp with a meat thermometer.
Method 2: Reverse Sear
- Preheat oven to 275°F.
- Place steaks on a wire rack over a baking sheet.
- Bake until internal temp reaches 10°F below your target.
- Heat a skillet on high with oil and butter.
- Sear each side for 45 to 60 seconds.
- Rest and serve.
Internal Temperature Guide For Doneness
Oven temp is only half the story. The internal temp tells you when to pull the steak.
- 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
Always pull the steak 5°F below your target. The temp will rise while it rests.
How Long To Cook Filet Mignon At Each Temperature
Cooking times depend on thickness. A 1.5-inch steak cooks faster than a 2-inch one.
At 425°F
- 1 inch thick: 4 to 5 minutes
- 1.5 inches thick: 6 to 7 minutes
- 2 inches thick: 8 to 10 minutes
At 350°F
- 1 inch thick: 8 to 10 minutes
- 1.5 inches thick: 12 to 15 minutes
- 2 inches thick: 18 to 22 minutes
At 275°F (Reverse Sear)
- 1 inch thick: 20 to 25 minutes
- 1.5 inches thick: 30 to 40 minutes
- 2 inches thick: 45 to 55 minutes
These are estimates. Your oven may run hot or cold. Use a thermometer every time.
Tips For Better Results
- Let the steak sit out for 20 to 30 minutes before cooking.
- Pat the surface dry with a paper towel. Moisture stops browning.
- Use a cast iron skillet. It holds heat better than nonstick.
- Add butter, garlic, and thyme near the end for flavor.
- Rest the steak for 5 to 10 minutes before slicing.
- Slice against the grain for a more tender bite.
Common Mistakes To Avoid
Cooking Straight From The Fridge
A cold center means uneven cooking. The outside overcooks before the inside warms up.
Not Using A Thermometer
Guessing doneness by touch or time alone leads to overcooked steak. A digital thermometer costs little and saves dinner.
Overcrowding The Pan
Steaks need space. If they touch, they steam instead of sear.
Skipping The Rest
Resting lets juices redistribute. Cut too soon and the juice runs onto the plate, leaving dry meat.
Choosing The Right Pan And Rack
For high heat methods, use a cast iron or stainless steel skillet. Both are oven safe to 500°F or higher.
For the reverse sear, use a wire rack on a rimmed baking sheet. Air moves around the steak for even cooking.
Always check that your pan is oven safe. Plastic handles and some nonstick coatings cannot handle 400°F or more.
Seasoning Before And After Cooking
Salt the steak at least 40 minutes before cooking, or right before it hits the pan. Skip the middle window, since salt pulls moisture to the surface.
Black pepper can burn at high heat. Add it after searing, or use coarse pepper and accept a little char.
Finish with flaky salt and a small pat of butter after resting.
Resting And Serving
Rest the steak on a warm plate, loosely covered with foil. Five minutes for thin cuts, up to 10 for thick ones.
Slice into thick pieces, about half an inch. This keeps the meat warm and juicy.
Serve with simple sides like roasted potatoes, sauteed spinach, or a light salad.
Quick Summary
Use 425°F for a fast sear, then finish at 350°F. Or go low at 275°F and sear at the end.
Pull the steak at 5°F below your target doneness. Rest it, then slice against the grain.
With the right oven temp and a good thermometer, filet mignon turns out tender and juicy every time.
