Ingredients:
- 2 filet mignon steaks (200g each, 1.5 to 2 inches thick)
- 15g unsalted butter
- 15ml avocado oil
- 120ml heavy cream
- 30g Dijon mustard
- 40g freshly grated Parmesan cheese
- 1 small shallot, finely minced
- 2 cloves garlic, minced
- 5g fresh thyme, chopped
- 0.5 tsp coarse sea salt
- 0.25 tsp freshly cracked black pepper
Instructions:
- Remove steaks from refrigeration 30 minutes prior to cooking to reach room temperature (tempering).
- Pat steaks completely dry with paper towels. Season aggressively with sea salt and black pepper on all sides and edges.
- Heat oil in a heavy-bottomed skillet over medium-high heat until shimmering. Sear steaks for 3-4 minutes without moving them to develop a mahogany crust.
- Flip the steaks, add butter to the pan, and baste the steaks with the foaming butter for an additional 3 minutes until internal temperature reaches 54°C (130°F).
- Remove steaks to a warm plate to rest. Reduce pan heat to medium and sauté minced shallots and garlic in the remaining fat for 1 minute.
- Whisk heavy cream and Dijon mustard together, then pour into the skillet to deglaze the fond. Simmer for 2 minutes until thickened.
- Stir in grated Parmesan and fresh herbs until the sauce is glossy. Serve immediately over the rested steaks.
