For the Lamb Steak
Saffron and Mushroom Sauce
In a small bowl, add the saffron threads to 2 tablespoons of hot water. Let them infuse for 10–15 minutes while you prepare the lamb.
Prepare and sear the lamb
Remove the lamb steaks from the refrigerator 20–30 minutes before cooking and pat them dry with paper towels.
Season both sides generously with salt and pepper.
Heat a heavy-bottomed skillet or cast-iron pan over medium-high heat with olive oil until it is very hot.
Place the lamb steaks in the hot pan and sear for 2–3 minutes per side, until a deep golden-brown crust forms.
Reduce the heat to medium and add 1 tablespoon of butter, the minced garlic, and the rosemary sprig.
Continue cooking, basting the steaks with the flavored butter for another 3–5 minutes until the desired doneness is reached (145°F for medium-rare).
Remove the lamb steaks from the pan, tent loosely with foil, and let them rest for at least 5 minutes. This is crucial for keeping the meat tender and juicy.
Prepare the saffron and mushroom sauce
While the lamb rests, use the same skillet over medium heat. Add the remaining 1 tablespoon of butter.
Sauté the chopped shallots and mushrooms until the mushrooms are tender and have browned, about 5–6 minutes.
Add the minced garlic and cook for another minute until fragrant.
Pour in the white wine or chicken stock to deglaze the pan, scraping up any browned bits from the bottom. Let the liquid simmer for 1–2 minutes to reduce slightly.
Stir in the saffron-infused water and the heavy cream. Let the sauce simmer gently for 2–3 minutes until it has thickened.
Season the sauce with salt and pepper to taste
