Ingredients You’ll Need
This Butter-Basted Filet Mignon with Rosemary Recipe calls for just a handful of simple, quality ingredients. Each one plays a critical role in building layers of flavor, from the juicy, tender steak to the buttery, herb-infused sauce that finishes the dish beautifully.
- 2 filet mignon steaks: Look for steaks about 1.5 to 2 inches thick for the perfect balance of sear and tender center.
- 4 tablespoons unsalted butter: Essential for basting and adding richness without overpowering the delicate meat.
- 2 sprigs fresh rosemary: Fresh rosemary infuses the butter with an aromatic earthiness that complements the beef perfectly.
- 2 cloves garlic, smashed: Adds a subtle pungent kick and depth of flavor during the basting process.
- Salt to taste: Proper seasoning enhances and brings out the natural flavors of the filet.
- Pepper to taste: Freshly ground black pepper adds just the right amount of heat and complexity.
How to Make Butter-Basted Filet Mignon with Rosemary Recipe
Step 1: Bring Steaks to Room Temperature
Start by removing your filet mignon from the fridge and letting it sit out for about 30 minutes. This step ensures even cooking from edge to center, resulting in a perfectly tender, juicy steak.
Step 2: Season the Filets
Generously season both sides of the steaks with salt and pepper. Don’t be shy here—seasoning is key to flavor, and your meat will soak it all up during cooking.
Step 3: Sear the Steaks
Heat a heavy skillet over high heat until it’s screaming hot. Place your filets in the pan and sear without moving them for about 3 to 4 minutes per side. The goal is a beautiful, brown crust that locks in all those delicious juices.
Step 4: Add Butter, Rosemary, and Garlic
Once your filets are nicely seared, lower the heat to medium. Add the butter, rosemary sprigs, and smashed garlic cloves to the pan. The butter will melt and mingle with the herbs and garlic, creating an aromatic bath for the steak.
Step 5: Butter-Baste to Perfection
Using a spoon, continuously baste the steaks with the melted butter, rosemary, and garlic mixture. This not only enhances flavor but also helps cook the steaks evenly. Continue basting and cooking for an additional 3 to 4 minutes, or until your preferred doneness is reached.
Step 6: Rest Before Serving
Remove the steaks from the skillet and let them rest on a cutting board or plate for at least 5 minutes. Resting allows the juices to redistribute, ensuring every bite is gloriously moist and tender.
How to Serve Butter-Basted Filet Mignon with Rosemary Recipe

Garnishes
Garnish with a small sprig of fresh rosemary or a light sprinkle of flaky sea salt to elevate the presentation and add a subtle flavor touch. A drizzle of the pan-basting butter over the steak right before serving adds a mouthwatering gloss.
Side Dishes
This rich, buttery steak pairs beautifully with creamy mashed potatoes, roasted asparagus, or a crisp green salad. For a heartier meal, caramelized mushrooms or a truffle-infused risotto can make a decadent accompaniment.
Creative Ways to Present
Impress your guests by slicing the filet mignon into medallions and fanning them out on the plate. Drizzle with the rosemary garlic butter and place a wedge of lemon or a colorful vegetable confetti for a pop of brightness. Serving alongside a small ramekin of compound herb butter adds a gourmet touch.
Make Ahead and Storage
Storing Leftovers
If you happen to have any leftovers from this Butter-Basted Filet Mignon with Rosemary Recipe, wrap them tightly in aluminum foil or place in an airtight container and refrigerate. Steak tends to stay delicious for up to 3 days refrigerated.
Freezing
While freezing cooked filet mignon is possible, it’s best enjoyed fresh due to its delicate texture. However, you can freeze uncooked, seasoned steaks wrapped carefully to enjoy later. Thaw in the refrigerator overnight for best results.
Reheating
To reheat leftover steak without drying it out, gently warm it in a skillet over low heat with a splash of beef broth or water, covering it to preserve moisture. Avoid microwave reheating, which can make the meat tough.
FAQs
Can I use other herbs besides rosemary?
Absolutely! While rosemary is classic for this recipe, thyme or sage make wonderful alternatives that complement the richness of the butter and filet perfectly.
How do I know when the steak is done?
Using an instant-read thermometer is the easiest way: 125°F for rare, 135°F for medium-rare, and 145°F for medium. The butter basting will help gently carry the steak to your desired doneness.
Can this recipe be doubled for more servings?
Yes, but be sure to cook the steaks in batches if your skillet isn’t large enough to avoid overcrowding, which can prevent proper searing.
Is butter-basting healthy?
While butter adds richness and flavor, it is calorie-dense, so enjoy this dish as an occasional indulgence or balance with lighter sides for a wholesome meal.
What type of pan works best for searing filet mignon?
A heavy-bottomed skillet such as cast iron is ideal as it maintains high heat evenly, enabling the perfect crust to form quickly on the steaks.

Butter Basting
- 4 tablespoons unsalted butter
- 2 sprigs fresh rosemary
- 2 cloves garlic, smashed
- Salt to taste
- Pepper to taste
Instructions
- Bring steaks to room temperature: Remove the filet mignon steaks from the refrigerator and let them sit uncovered at room temperature for about 30 minutes. This ensures even cooking throughout the steak.
- Season the steaks: Generously season both sides of each filet mignon with salt and freshly ground black pepper to enhance the natural flavors of the beef.
- Sear the steaks: Heat a heavy skillet over high heat until very hot. Place the filet mignon steaks in the skillet and sear without moving for 3-4 minutes on one side until a rich brown crust forms.
- Flip and prepare for basting: Turn the steaks over and sear the other side for 3-4 minutes to develop an even crust.
- Add butter, rosemary, and garlic: Reduce the heat to medium, then add the unsalted butter, fresh rosemary sprigs, and smashed garlic cloves to the pan. Let the butter melt and infuse with the aromatics.
- Baste the steaks: Tilt the pan slightly and use a spoon to continuously baste the steaks with the melted butter mixture. Continue cooking and basting for another 3-4 minutes or until the steaks reach your preferred level of doneness.
- Rest the steaks: Remove the filet mignon from the skillet and transfer to a plate. Let them rest for 5 minutes to allow the juices to redistribute, ensuring a tender and juicy bite.
Notes
- Allowing the steaks to come to room temperature prevents uneven cooking.
- Use a heavy-bottomed skillet (such as cast iron) for better heat retention and searing.
- Basting with butter keeps the meat moist and enhances flavor with garlic and rosemary.
- Letting the steak rest after cooking helps retain juices and prevents dryness.
- Adjust cooking time according to thickness and desired doneness (medium-rare is usually recommended for filet mignon).
