Mix all the spices in a small bowl until well combined. If you can smell it already, you’re doing it right.
Pat dry the meat and toss with olive oil. This helps the seasoning cling like a loyal sidekick.
Rub the spice blend all over the meat. Don’t be shy—give it a good massage so every bit is coated.
Marinate for at least 30 minutes, or up to 4 hours for deeper flavor. If you’re in a rush, 15 minutes will still be tasty.
Cook on a hot grill or skillet until the meat is cooked through and nicely charred at the edges. Turn once to get that even finish.
Let rest for a few minutes, then slice thinly for the gyro assembly. Pro tip: rest is the secret to juicy meat.
