# Expert Advice:

01 -
  • The mustard crust gets crispy while the meat stays tender inside, creating a textural contrast that feels indulgent but takes less than an hour.
  • Fresh herbs actually taste like themselves here instead of fading into the background, especially if you chop them just before mixing.
  • It's naturally gluten-free and impressive enough for guests, but casual enough to make on a Tuesday when you want something special.
02 -
  • The lamb will keep cooking slightly after you pull it from the oven, so pull it out a touch early rather than overcooking; a meat thermometer is not optional here, it's your best friend.
  • Pat the meat dry before searing—I learned this the hard way when steam ruined my sear, and I watched the crust refuse to brown properly.
  • The herb crust only sticks well to meat that's still warm from searing; don't let it cool completely before coating.
03 -
  • Let your butcher trim the lamb rack if you ask nicely; they'll make sure the bones are clean and the meat is ready to sear, which saves you time and guarantees better results.
  • Gather all your herbs before you start cooking so you're not frantically chopping while the lamb cools; mise en place matters more here than anywhere else.
  • A meat thermometer removes all the guesswork and anxiety, turning this from a dish you're worried about into one you know will be perfect.
