Ingredients (Serves 4)
For the Filet Medallions:
- 4 beef tenderloin medallions (1.5 inches thick)
- 2 tbsp olive oil
- 2 tbsp unsalted butter
- 2 garlic cloves, minced
- 1 tsp fresh thyme (or ½ tsp dried)
- ½ tsp kosher salt
- ½ tsp freshly ground black pepper
For the Garlic Butter Pan Sauce:
- ½ cup beef broth
- 1 tbsp balsamic vinegar
- 1 tsp Dijon mustard
- 1 tbsp butter
Optional Garnishes:
- Fresh parsley or rosemary
- Cracked black pepper
Step-by-Step Instructions
1. Bring to Room Temperature
Remove medallions from the fridge 30–40 minutes before cooking to ensure even searing.
2. Season the Steaks
Pat dry with paper towels. Season generously with salt and pepper on both sides.
3. Sear the Medallions
Heat olive oil in a cast iron skillet over medium-high. Once shimmering, add medallions and sear for 3–4 minutes per side until golden-brown crust forms.
4. Baste with Garlic Butter
Lower heat to medium. Add butter, garlic, and thyme. Spoon the melted butter over the medallions for 1–2 minutes for extra flavor.
5. Let Them Rest
Transfer steaks to a plate, tent with foil, and rest for 5–10 minutes to lock in juices.
6. Make the Sauce
Deglaze skillet with beef broth, scraping browned bits. Simmer 5 minutes, then stir in balsamic vinegar and Dijon mustard. Finish with a swirl of butter.
7. Plate and Serve
Serve medallions topped with pan sauce. Garnish with herbs and cracked pepper, if desired.
Optional Marinade for Extra Flavor
Although not necessary, marinating adds depth. Here’s a quick and effective marinade:
Simple Soy-Balsamic Marinade:
- ¼ cup low-sodium soy sauce
- 1 tbsp Worcestershire sauce
- 1 garlic clove, minced
- 1 tbsp olive oil
- 1 tsp brown sugar
Marinate for 2–8 hours. Always pat dry before searing to get that perfect crust.
