Today I’m sharing how to reverse sear filet mignon for a cozy, romantic dinner. Topped with a silky brandy peppercorn sauce, this recipe feels elevated yet remains simple to prepare — perfect for date night at home or an elegant dinner with friends. Pour a glass of wine and treat yourself to a restaurant-quality steak without leaving the kitchen.
When I want to celebrate or simply indulge, steak is my go-to. I have many favorite dishes, but a perfectly cooked steak is always near the top of the list. Filet mignon holds a special place — tender, rich, and inherently romantic. Paired with a creamy peppercorn sauce, it becomes an unforgettable meal.
I learned the reverse sear method in culinary school, and it changed the way I cook steak. Low-and-slow roasting followed by a quick hot sear yields the most consistent, tender results. Here are a few reasons to try this recipe:
- The filet mignon is rich, buttery, and remarkably tender.
- Reverse searing ensures even cooking and predictable, repeatable results.
- The brandy peppercorn sauce adds a luxurious, creamy finish.
- Ideal for date nights, special occasions, or dinner parties.
Beef tenderloin vs filet mignon
Filet mignon is often confused with beef tenderloin because they come from the same area of the animal, but they are not identical. The tenderloin is a long, whole muscle cut from the rear back near the sirloin; filet mignon is a small, prized portion taken from the narrow end of that tenderloin. Filets are prized for their tenderness and buttery texture.
For the best results, choose filets that are bright red with light marbling and little to no silver skin. Trim away any large pieces of fat or connective tissue so every bite is tender and not chewy.
When selecting steaks, look for consistent thickness so they cook evenly. If you see chunks of fat or silverskin, trim them before cooking for the best texture.
Brine & roast the steaks
Cook the filets low and slow (about 225°F / 107°C) to gently bring the internal temperature up without overcooking the exterior. This method produces a tender, evenly cooked steak with a melt-in-your-mouth texture. If the oven heat is too high, the meat can dry out.

Temperature guide
Temperature control is the key to a perfect steak. Use a reliable meat thermometer and follow this guide for oven and final searing temperatures:
| Doneness | Oven Internal Temp | Searing Internal Temp |
| Rare | 105–110°F | 120–125°F |
| Medium Rare | 110–115°F | 130–135°F |
| Medium | 120–125°F | 140–145°F |
| Medium Well | 130–135°F | 150°F |
| Well Done | 140–145°F | 160°F |
For tender, juicy filet mignon, avoid cooking past medium. Medium rare yields the best texture and flavor.
I recommend using a meat thermometer — it’s the most reliable way to ensure your steaks are cooked exactly how you like them. If you don’t have one, err on the side of undercooking; you can always sear longer to increase the internal temperature.
Store & reheat leftovers
Store leftover steak in an airtight container in the refrigerator for up to 3–4 days. Reheat gently in a low oven: set the oven to 225°F and warm the steaks for about 20 minutes or until heated through. This method helps retain moisture better than microwaving.
Filet mignon is best enjoyed fresh. Because it’s a premium cut, plan to cook it right before serving to preserve the texture and flavor.

Reverse Sear Filet Mignon with Peppercorn Sauce
Ingredients
Reverse Seared Filet Mignon
- 4 filet mignon steaks (6–8 ounces each / 168–225 grams each)
- Kosher salt and freshly ground black pepper to taste
- 1 Tablespoon neutral oil (canola or avocado; 14 milliliters)
- 1 Tablespoon unsalted butter (14 grams)
Brandy Peppercorn Sauce
- 1/4 cup minced shallots (35 grams / 1 small shallot)
- 2 teaspoons minced garlic (2 large cloves)
- 1 Tablespoon all-purpose flour (8 grams)
- 1/4 cup brandy (55 milliliters)
- 3/4 cup low-sodium beef broth (170 milliliters)
- 1/2 cup heavy whipping cream (130 milliliters)
- 1 Tablespoon Dijon mustard (15 grams)
- 2 teaspoons coarsely ground black peppercorns
Equipment
-
Sheet pan
-
Tinfoil or parchment paper
-
Cast iron skillet
-
Meat thermometer
Instructions
-
Line a sheet pan with tinfoil or parchment and place a wire cooling rack on top. Generously season the steaks with kosher salt and set them on the rack. Let the steaks sit uncovered at room temperature for 1 hour, or refrigerate uncovered overnight for a dry brine. If chilled, bring the steaks to room temperature for 30 minutes before cooking.
-
Preheat the oven to 225°F (107°C). Pat the steaks dry, season both sides with freshly ground black pepper, and place them directly on the prepared pan. Roast until an instant-read thermometer inserted into the thickest part registers 110–115°F (43–46°C) for medium-rare, about 25–28 minutes. Begin checking at 20 minutes. Transfer steaks to a plate and rest 5–8 minutes.
-
Heat a cast iron skillet over medium-high. Add the butter and oil and swirl to coat. When the fat is very hot and shimmering, sear the steaks 2 minutes per side, flipping every 30 seconds, until a deep brown crust forms. Transfer steaks to a clean plate and rest 5–8 minutes while you make the sauce.
Brandy Peppercorn Sauce
-
Using the same skillet, pour off all but 1 tablespoon of pan drippings and return the pan to medium heat. Add shallots and cook until softened, about 2–3 minutes. Add garlic and cook 30 seconds until fragrant.
-
Stir in the flour and cook 1 minute to remove the raw taste. Deglaze with brandy, scraping up browned bits, and simmer until the brandy reduces by about half, roughly 2 minutes.
-
Add beef broth and simmer until slightly reduced, about 2–3 minutes. Stir in the cream, Dijon mustard, and coarsely ground peppercorns. Simmer for 2 minutes until the sauce thickens slightly and coats the back of a spoon. Taste and adjust seasoning if needed. Spoon the warm sauce over the steaks and serve.
Notes
Season generously with kosher salt; meat handles more salt than you might expect and proper seasoning brings out deeper flavor.
A meat thermometer is the most reliable way to hit your desired doneness. If unsure, undercook slightly — you can always sear longer to raise the temperature.
Do not overcrowd the pan when searing. Give each steak space to brown properly; sear in batches if necessary.
For a darker sauce appearance, a small dash (about 1/4 teaspoon) of browning sauce can be added for color only; this is optional.
