Okay, this sounds weird. But your nose knows. Raw lamb has a distinct, grassy, slightly funky smell. As it cooks, that smell changes.
When it’s perfectly cooked, the aroma should be savory, nutty, and a little sweet. If you smell a strong, gamey, or metallic scent, you might have overcooked it. Or burnt the fat. Neither is a good look.
If it smells like a cozy campfire but also a little bit like a flower? You’re on the money.
The Broken Clock Method
Finally, here’s a lazy trick. For lamb chops about 1-inch thick, give them 3-4 minutes per side on high heat. Then immediately poke them with the finger test. If your brain says “hmm, maybe another minute,” stop. Take them off. You are probably right the first time.
When in doubt, undercook it slightly. You can always throw it back on the heat for an extra 30 seconds. You cannot un-cook a piece of shoe leather. Literally, you cannot. I’ve tried.
So go forth. Be brave. Poke that meat. Trust your hand. And for the love of all things fluffy, let the poor lamb rest before you serve it. You got this.
