Fillet Steak Recipes: Pan-Seared Steak with Herb Butter

This pan-seared fillet steak is a tender beef steak with a deeply browned crust, finished with garlic, herbs, and melting butter. The method uses a skillet and a brief oven finish, making it a straightforward special-occasion dinner that also works on a weeknight when you want a reliable steak without a grill.

Ingredients

4 beef fillet steaks, about 1½ inches (4 cm) thick and 6 ounces (170 g) each
1 teaspoon fine sea salt (6 g)
½ teaspoon freshly ground black pepper (1 g)
1 tablespoon neutral high-heat oil, such as canola or grapeseed (15 ml)
3 tablespoons unsalted butter (42 g), cut into 3 pieces
2 garlic cloves (about 6 g), lightly crushed and peeled
1 teaspoon finely chopped fresh rosemary (about 1 g)
1 teaspoon fresh thyme leaves (about 1 g)

Instructions

Season and take the chill off. Pat the steaks dry on all sides with paper towels; a dry surface browns more effectively than a damp one. Trim away any large, loose pieces of silverskin, but leave a thin outer edge of fat in place if there is one. Season all over with the salt and pepper. Set the steaks on a plate or small rack at room temperature for 20 minutes while you prepare the pan and heat the oven. Do not leave raw meat out longer than 2 hours total, and keep it away from ready-to-eat foods.
Heat the oven and skillet. About 10 minutes before cooking, heat the oven to 400°F (204°C). Set a heavy, oven-safe skillet, preferably cast iron or stainless steel, over medium-high heat. Let it heat for several minutes until thoroughly hot. Turn on the exhaust fan if needed; a little smoke is possible once the oil goes in, but the oil should not be burning heavily.
Sear the steaks. Add the oil and swirl to coat the pan. Lay the steaks in the skillet with space between them. They should make a clear, lively sizzle. Leave them undisturbed for 2 minutes, then turn with tongs and sear the second side for 2 minutes. Use the tongs to briefly sear the narrow edges, about 30 seconds per edge where practical. Avoid pressing down on the steaks, which squeezes out juices and does not improve browning.
Add the butter and aromatics. Lower the burner to medium. Add the butter, garlic, rosemary, and thyme. When the butter has melted and begun to foam, tilt the skillet carefully and spoon the foaming butter over the steaks for about 30 seconds. This adds flavor, but it is not a substitute for checking the center temperature. If the butter starts to turn very dark or smell acrid, move the pan off the burner briefly.
Finish in the oven and check doneness. Transfer the oven-safe skillet to the preheated oven. Roast for about 6 to 9 minutes, checking the thickest steak after 6 minutes. Insert an instant-read food thermometer horizontally into the center from the side, avoiding contact with the pan. For food safety, the USDA FSIS safe minimum for whole cuts of beef is 145°F (63°C), followed by a 3-minute rest; return the steaks to the oven in short intervals if they have not reached that temperature. Thickness, starting temperature, and pan heat all affect the timing, so use the thermometer rather than relying on minutes alone.
Rest and serve. Move the steaks to a warm plate or cutting board and rest for 5 minutes before serving. The rest gives the juices time to settle and exceeds the required 3-minute safety rest. Spoon a little of the herb butter over each steak. Do not pour very hot pan fat over the resting meat if it has begun to scorch; instead, use the clean, fragrant butter and herbs from the pan.

Tips

Choose steaks of similar thickness. Four steaks that are close to 1½ inches thick will finish at roughly the same time. If one is much thinner, check it earlier and remove it as soon as it reaches the safe minimum temperature. A digital instant-read thermometer is the most dependable way to avoid guessing.
Dry the surface and give the pan room. Moisture creates steam, which slows browning. If your skillet is too small to hold all four steaks without crowding, sear them in two batches. Keep the first batch warm on a plate while the second sears, then put the steaks in the oven together if your pan and timing allow.
Use oil for the first sear and butter near the end. Butter can burn during a long, very hot sear. A neutral oil handles the initial heat better, while adding butter after the crust forms gives the steaks a rich finish without leaving the garlic and herbs in the pan for the entire cooking time.
Adjust salt to the kind you have. This recipe specifies fine sea salt. If using a coarse kosher salt, the same teaspoon can weigh less and season differently, so measure by weight if possible or use a little less at first. You can add a small pinch at the table, but you cannot take excess salt back out.

Serving Suggestions

For a classic plate, serve each steak with mashed potatoes or crisp roasted potatoes and a green vegetable such as asparagus, green beans, or broccoli. The potatoes catch the garlic-herb butter, while a simply dressed salad adds a fresh contrast to the richness of the beef. For a lighter side, try sautéed mushrooms and spinach, or serve sliced steak over a bowl of peppery greens with a lemony vinaigrette.

To make the meal feel more complete, put any extra pan juices in a small warm dish for spooning at the table. A sauce is optional: fillet is naturally tender and does not need a complicated topping. If serving guests, bring the steaks to the table whole and slice them just before eating, or slice across the grain into thick pieces and arrange them on a warm platter. Use clean serving utensils rather than the ones that handled the raw steaks.

Variations

Peppercorn finish: Increase the black pepper to 1 teaspoon (2 g) and, after removing the steaks, stir 1 teaspoon (5 g) Dijon mustard and ½ cup (120 ml) beef stock into the pan. Simmer briefly, scraping up browned bits, then stir in 2 tablespoons (30 ml) cream. The sauce will be thinner than a traditional long-simmered peppercorn sauce, but it gives the plate a savory, peppery finish. Keep the pan off high heat when adding cream so it does not split.

Blue cheese butter: Leave out the rosemary and thyme. Mash 2 tablespoons (28 g) softened butter with 1 ounce (28 g) crumbled blue cheese and a pinch of black pepper, then place a little on each hot steak after resting. This is a quick alternative to the skillet butter and has a stronger, tangier flavor; use less salt on the meat if the cheese is salty.

Simple red-wine pan sauce: After transferring the steaks to rest, carefully pour off excess fat, leaving the browned bits in the skillet. Add ½ cup (120 ml) beef stock and ¼ cup (60 ml) dry red wine, simmer until reduced by about half, then whisk in 1 tablespoon (14 g) cold butter. Wine is optional; use an additional ¼ cup (60 ml) stock instead for an alcohol-free version, though the sauce will taste less fruity. Never add liquid to a smoking-hot pan all at once; lower the heat and pour carefully.

Grill option: The same seasoning and herb butter work on a preheated grill. Sear over direct heat, turning as needed for browning, then move the steaks to a cooler area to finish. The exact time varies with grill temperature and steak thickness, so check the center with a food thermometer and follow the same USDA safe minimum and rest guidance. The grill gives the outside a lightly smoky flavor compared with the skillet method.

Storage and Reheating

Refrigerate cooked steak within 2 hours of cooking, in a shallow airtight container. It keeps for 3 to 4 days in the refrigerator. Store any sauce separately if convenient, and do not leave cooked steak at room temperature while serving for an extended period. For longer storage, freeze it in a well-sealed, freezer-safe container; for best texture, use within 2 to 3 months. Thaw frozen portions in the refrigerator rather than on the counter.

Reheating can make lean fillet less tender, so warm only the portion you plan to eat. For the gentlest result, place steak in a covered oven-safe dish with a spoonful of stock or water and heat in a 250°F (121°C) oven until warmed through, checking the center with a thermometer. USDA FSIS guidance is to reheat leftovers to 165°F (74°C). You can also slice cold leftover steak thinly and add it to a hot dish near the end of cooking, but the finished leftovers still need to reach 165°F (74°C). Avoid repeatedly cooling and reheating the same portion.

Frequently Asked Questions

What is fillet steak?

Fillet steak is cut from the tenderloin, a long, relatively lean muscle along the back of the animal. It is valued for its tender texture and mild beef flavor. Names and exact cuts vary by country and butcher; filet mignon commonly refers to a thick steak portion from the smaller end of the tenderloin.

Can I cook fillet steak entirely on the stovetop?

Yes, especially if the steaks are thinner than the 1½-inch pieces in this recipe. Sear them in a hot skillet, then lower the heat and continue turning them until the center reaches the USDA safe minimum temperature of 145°F (63°C), followed by a 3-minute rest. With thick steaks, the oven finish makes it easier to brown the outside without leaving the center underheated.

How do I know when the steak is done?

Check the thickest steak with an instant-read thermometer inserted into the center from the side. Color and firmness can be misleading, particularly with a thick cut, and cooking times change with the stove, pan, and starting temperature. The USDA FSIS safe minimum for a whole cut of beef is 145°F (63°C) with a 3-minute rest, so use that as the safety benchmark.

Can I use a nonstick skillet?

A heavy cast-iron or stainless-steel pan is preferable because it holds heat well and can usually go straight into the oven. If using nonstick, first check the manufacturer’s maximum oven temperature and whether the handle is oven-safe. Some nonstick pans are not suitable for high-heat searing or oven finishing; in that case, sear in the pan and transfer the steaks to a preheated oven-safe dish.

Can I prepare the steaks ahead?

You can season the steaks and refrigerate them, uncovered on a rack over a tray, for several hours; this helps keep the surface dry. Keep raw beef refrigerated at 40°F (4°C) or below, and bring it out only for the short 20-minute tempering period in the recipe. Pat away any surface moisture before searing, and do not leave raw steak at room temperature for more than 2 hours total.

What can I do with leftover fillet steak?

Slice cold leftovers thinly for a sandwich, salad, or grain bowl, or stir slices into a hot pan of vegetables just before serving. For a warm leftover meal, reheat safely to 165°F (74°C), knowing that the texture will be firmer than freshly cooked steak. Keep leftovers refrigerated for 3 to 4 days and discard them if they have been left out longer than 2 hours.
