1 tablespoon dried thyme

1 teaspoon dried rosemary

1 1/2 tablespoons kosher salt

1 tablespoon olive oil

For the Onion Gravy:

1/4 cup flour

2 tablespoons honey Dijon mustard

1/2 cup white cooking wine (or chicken broth)

3 cups chicken broth

Salt and pepper, to taste

Instructions

Prep the lamb: Let lamb rest at room temp. Slice garlic and insert into small cuts all over the lamb.

Make the rub: Blend garlic, oregano, thyme, rosemary, salt, pepper, mustard, and olive oil into a paste. Rub over the entire lamb.

Prepare roasting pan: Layer onions, carrots, and garlic in the pan. Toss with olive oil, salt, and pepper.

Place lamb on a roasting rack over the vegetables. Let sit with rub for 15–60 minutes.

Preheat oven to 500°F (260°C). Place lamb in the oven for 10 minutes.

Without opening the door, reduce oven to 400°F (204°C). Roast for an additional 1 hr 10–25 mins until desired internal temperature (see Notes).

Remove lamb and rest for 20 minutes, tented with foil.

Make the gravy: Use pan drippings and onion mixture. Whisk in flour, then mustard, wine, and broth gradually. Simmer until thickened.

Slice lamb: Follow bone contours for clean slices. Serve with roasted carrots and onion gravy.

Notes

Onion Choice: Red onions add subtle sweetness, but white or yellow onions work too.
