Few meals feel as genuinely celebratory as a perfectly seared filet mignon, and this version delivers that steakhouse experience entirely from your own kitchen. The technique here is classic and precise — a screaming-hot cast iron sear followed by a quick oven finish — which builds a deep, caramelized crust while keeping the center tender and rosy. What makes this recipe especially smart is the herb butter, which swaps conventional dairy butter for softened ghee, keeping everything compliant without sacrificing any of that rich, melting finish you want pooling over a rested steak. Fresh parsley, thyme, rosemary, garlic, and a hint of lemon zest make that compound butter genuinely fragrant and bright, not just a workaround. Avocado oil handles the high-heat sear without issue, and every other ingredient on the list is clean and straightforward — no hidden additives, no label-reading required. The resting step is non-negotiable and the recipe respects that, giving the juices time to redistribute so every slice is as good as the first. This is the kind of dish that makes a reset feel less like a restriction and more like an upgrade.

Preheat the oven to 425°F (220°C). Remove the steaks from the refrigerator 20–30 minutes before cooking and pat them completely dry with paper towels. Season all sides evenly with the kosher salt and black pepper.
In a small bowl, combine the softened ghee, parsley, thyme, rosemary, garlic, flaky sea salt, and lemon zest, if using. Stir until evenly mixed, then set aside at room temperature.
