Key Ingredients

These basic ingredients work together to create a juicy, flavorful steak with a rich herb finish.

• 2 filet mignon steaks (6–8 oz each): Soft, tender cuts that cook quickly and stay juicy
• 2 tablespoons olive oil: Helps achieve a golden sear without burning
• 2 teaspoons salt: Enhances natural beef flavor
• 1 teaspoon black pepper: Adds light heat and depth
• 2 tablespoons unsalted butter: Creates a rich, silky finish
• 4 garlic cloves, minced: Adds bold aroma and savory flavor
• 2 sprigs fresh rosemary (or 1 tsp dried): Earthy herbal notes
• 2 sprigs fresh thyme (or 1 tsp dried): Subtle fragrance and warmth

How To Make Oven Filet Mignon

This method combines stovetop searing with oven roasting for the perfect steak texture—crispy outside, tender inside.

1. Preheat oven to 400°F (200°C) so it’s ready when the steaks are seared.
2. Take steaks out of the fridge and let them rest for 25–30 minutes to reach room temperature.
3. Pat steaks dry using paper towels to help form a strong crust.
4. Season both sides generously with salt and black pepper.
5. Heat olive oil in an oven-safe skillet over medium-high heat until hot and shimmering.
6. Place steaks in the pan and sear for 3–4 minutes without moving them.
7. Flip the steaks and reduce slight heat, then add butter, garlic, rosemary, and thyme to the pan.
8. Spoon melted butter over the steaks continuously for 1–2 minutes for extra flavor.
9. Transfer the skillet to the oven and bake for 5–7 minutes (medium-rare target).
10. Remove and let steaks rest for 5 minutes before slicing.
11. Serve warm with pan juices drizzled on top.

Serving Suggestions

• Roasted vegetables like asparagus, zucchini, or carrots for a light summer plate
• Garlic mashed potatoes for a creamy, comforting side
• Fresh green salad with lemon dressing for a refreshing balance
• Warm dinner rolls to soak up the herb butter sauce

Tips For Perfect Filet Mignon

• Always let the steak rest after cooking to keep it juicy
• Use a meat thermometer for accuracy (130°F for medium-rare)
• Don’t overcrowd the pan—each steak needs space to sear properly
• Fresh herbs give stronger flavor, but dried herbs also work well
• Basting with butter is key for restaurant-style richness

How To Store

• Refrigerate leftovers in an airtight container for up to 2 days
• Freeze tightly wrapped steaks for up to 1 month
• Reheat gently in a low oven (250°F) to avoid drying out
• Add a little broth or butter when reheating to restore moisture
