Tender, golden-crusted sirloin bites tossed in a fragrant garlic-herb ghee — this is the kind of dish that makes eating clean feel genuinely indulgent. The cast iron sear is everything here: patting the steak dry and cooking in a screaming-hot skillet builds that deep, caramelized crust without any sugar, starch, or inflammatory oils in sight. Avocado oil handles the high heat beautifully, while ghee brings rich, buttery depth that works perfectly for those avoiding conventional dairy. Fresh rosemary, thyme, and garlic bloom in the pan drippings, creating a sauce that coats every bite with serious flavor. A bright finish of lemon juice and parsley keeps the whole dish feeling light and vibrant rather than heavy. This recipe checks every box — no grains, no added sugars, no questionable ingredients — just clean, whole-food cooking that genuinely satisfies. Serve it straight from the skillet with extra lemon wedges and it's the kind of meal you'll want on repeat.

Pat the steak cubes thoroughly dry with paper towels, then season all over with the salt and black pepper.
Heat the avocado oil in a 12-inch cast iron skillet over high heat until the oil just begins to smoke. Add the steak cubes in a single layer, working in two batches if needed to avoid crowding, and sear undisturbed for 2 minutes until a deep brown crust forms on the underside. Flip and sear for 1–2 minutes more, until the steak reaches 145°F (63°C) on an instant-read thermometer for medium. Transfer to a plate and tent loosely with foil.
