For filet mignon, sear in a hot skillet, then roast at 400–450°F until 125–145°F inside, and rest 5 minutes for a tender, even bite.
Filet mignon shines when the crust crackles and the center stays rosy. The most reliable path is quick stove heat for color, then oven heat for control. Below you’ll get clear temps, timing by thickness, and a step-by-step that delivers repeatable results with standard kitchen gear.
Oven Timing After Sear (By Thickness And Doneness)
Use these oven ranges after a strong 1½–2 minute sear per side. Always confirm with an instant-read thermometer inserted from the side into the center.
| Thickness | Pull / Final Temp | Oven Time* |
|---|---|---|
| 1 inch | 120→125°F (rare) | 3–5 min |
| 1 inch | 125→130°F (med-rare) | 5–7 min |
| 1¼ inches | 125→130°F (med-rare) | 6–9 min |
| 1½ inches | 125→130°F (med-rare) | 8–12 min |
| 1½ inches | 130→135°F (medium) | 10–14 min |
| 2 inches | 125→130°F (med-rare) | 12–16 min |
| 2 inches | 130→135°F (medium) | 14–18 min |
*Times assume oven 425°F, heavy oven-safe skillet, room-temp steaks, and a strong sear. Pull temps are 5°F below your final target to account for carryover while resting.
Cooking Filet Mignon Steaks In Oven: Step-By-Step
Prep The Steaks
- Choose 1½–2-inch thick center-cut steaks for a wide rosy band.
- Pat dry all sides until the surface looks matte, not damp.
- Salt early or right before searing: either 40 minutes to overnight, or immediately before the pan. Both give a balanced crust; the middle window is the weak spot for moisture on the surface.
- Bring the steaks out of the fridge 20–30 minutes while you heat the oven.
Heat The Pan And Oven
- Set oven to 425°F (220°C). Place the rack in the center.
- Heat a heavy oven-safe skillet (cast iron or clad steel) over medium-high until it shimmers and a drop of oil moves freely.
- Add a thin film of high-smoke-point oil. You want a lively sizzle on contact.
Sear For Crust
- Lay steaks in the hot pan. Don’t crowd; leave space so steam can escape.
- Sear 1½–2 minutes per side until deep brown. Turn with tongs; press gently for even contact.
- Optional: tilt the pan and spoon foaming butter over the tops with a smashed garlic clove and a thyme sprig. Keep the butter sizzling, not burning.
Roast To Target Temp
- Move the skillet to the oven. Set a timer using the table above as a guide.
- Check early with a thermometer through the side. Aim for the pull temp (about 5°F under final) since carryover heat will finish the job on the board.
Rest, Slice, And Serve
- Transfer to a warm plate or board and rest 5–8 minutes to let the juices settle.
- Serve whole, or slice thick on the bias to show that rosy center.
Cook Filet Mignon In The Oven: Time And Temp Guide
Oven heat gives you control; the skillet gives you flavor. That balance turns a lean cut into a plush bite. Here’s how to pair your aim with your tools.
Pick Your Oven Temperature
- 400–425°F: best blend of crust and control for 1–2-inch steaks.
- 450°F: faster finish once you’re fluent with the method.
- Lower heat (350–375°F): a slower finish; handy if your sear ran darker than planned.
Pull Temperatures And Doneness
- Rare: pull 120°F, serve ~125°F.
- Medium-rare: pull 125°F, serve ~130°F.
- Medium: pull 130°F, serve ~135°F.
- Medium-well: pull 140°F, serve ~145°F.
For food-safety guidance, steaks are considered safe at 145°F after a short rest; use your thermometer and choose the level that matches your table.
Seasoning And Salting That Pay Off
Filet is mild. It loves salt, pepper, and heat. A bare steak with just salt and fresh pepper tastes rich when the crust is right. If you want more lift, add a little garlic, thyme, or a butter finish at the end. Keep sugars and sweet glazes away from the hot sear; add those later so they don’t scorch.
When To Salt
Two windows shine: long in advance or right before the pan. Early salting lets the surface re-dry for a crisp crust; last-minute salting brings a bold surface flavor without pulling out moisture right before heat. Avoid the middle window where the surface stays damp.
Smart Fat Choices
- Sear fat: neutral high-smoke oil (avocado, grapeseed, refined canola).
- Flavor fat: finish with butter in the last minute on the stove or after roasting to melt over the top.
- Pan aromatics: thyme, rosemary, garlic; add near the end so they don’t burn.
Gear And Setup For Even Results
Skillet And Rack
- Pan: 10–12-inch cast iron or thick stainless pan holds heat for a strong sear.
- Rack: keep a wire rack over a sheet pan nearby; it’s a tidy landing zone if you need to pause or rest.
- Tongs: long tongs for clean flips and edge searing.
- Thermometer: instant-read is non-negotiable for precise doneness.
Oil, Smoke, And Ventilation
Preheat until the pan is hot enough that a drop of oil thins out at once. Turn on the vent or crack a window. Brown flavor comes from fast surface drying and the browning reactions that follow; steam is the enemy of crust.
Common Mistakes And Easy Fixes
Pan Not Hot Enough
If the steak goes pale or weeps liquid, your pan is cool. Let it reheat, wipe the moisture, and try again. A good sear lays the flavor base before the oven finish.
Overcooking After A Perfect Sear
Check earlier than you think. Thin steaks finish fast once they hit the oven. Use the table ranges as a starting point and trust your thermometer.
Uneven Doneness
Start with even thickness and let steaks sit out while the oven heats. If one steak is thinner, stagger the oven entry by a minute or two.
Butter Burn
Butter browns fast. Add it late and keep it moving. If it starts to darken too far, tilt the pan to pool the fat and spoon quickly, or finish with butter off the heat.
Why Sear Then Roast Works
The pan dries and browns the surface in minutes, building a crackly crust. The oven then brings the center to temp gently, so the band of doneness stays even from edge to edge. Filet is lean, so control and carryover matter; pulling a few degrees early and resting on a warm plate keeps the center tender.
Quick Variations That Still Keep Control
Herb-Butter Finish
While the steaks rest, whisk softened butter with minced parsley, chives, lemon zest, and a pinch of salt. Dollop on the warm steaks so it melts across the top.
Pan Sauce In Two Minutes
After you pull the pan from the oven, set it on medium heat. Add a splash of stock or dry wine, scrape the browned bits, reduce to a syrup, and swirl in a knob of butter. Spoon over the sliced steak.
Peppercorn Crust
Crack whole peppercorns coarsely and press them lightly onto the salted surface before searing. Keep the pan hot and move quickly; pepper burns if left still.
Second Table: Doneness Targets And Carryover
Use these targets to plan your pull point and resting time.
| Doneness | Pull Temp | Final After Rest |
|---|---|---|
| Rare | 120°F | 125°F |
| Medium-rare | 125°F | 130°F |
| Medium | 130°F | 135°F |
| Medium-well | 140°F | 145°F |
| USDA safe | — | 145°F + 3-min rest |
| Carryover | — | +3–5°F |
| Rest time | — | 5–8 min |
Safety And Sourcing Notes
Use a clean board and tongs for cooked meat, and wash the raw board and knife in hot soapy water. Steaks reach their safe zone at 145°F after a short rest. If you prefer a cooler center, buy fresh, high-quality whole cuts, handle them cold, and sear in a clean pan.
Make The Most Of Leftovers
Chill leftovers fast. Slice cold for steak salads, or rewarm gently: bring to room temp, then give each side a quick kiss in a hot pan with a knob of butter. Stop as soon as the slices feel warm to the touch so they don’t push past your target.
When The Oven Isn’t An Option
If you only have a stove, keep the heat slightly lower after the initial sear and flip often. You can still hit precise temps; the flips help keep the band of doneness even. A probe thermometer with a cable makes this nearly hands-off.

Bottom Line: Repeatable Oven Method
Heat the skillet until it shimmers, sear hard for fast color, then move to a 400–450°F oven and cook by thermometer, not the clock. Pull 5°F shy of your final, rest a few minutes, and finish with a spoon of butter or a quick pan sauce. That’s cooking filet mignon steaks in oven made dependable, weeknight or date night.
