Ingredient Notes
Rack of Lamb
Ask your butcher for a frenched rack of lamb, which means the rib bones are trimmed clean. This presentation makes slicing easier and creates a beautiful dish when served.
Garlic
Fresh garlic is essential in this garlic roasted rack of lamb recipe. Roasting whole cloves alongside the lamb creates sweet, mellow garlic that adds incredible flavor.
Butter Alternatives
If you want a lighter option, you can replace part of the butter with olive oil. The flavor will still be rich but slightly less heavy.
Stock Powder Substitute
Chicken stock powder enhances the savory flavor of the lamb. If you prefer, you can substitute it with low-sodium vegetable broth powder.
Herb Variations
While thyme is classic for garlic roasted rack of lamb, rosemary or parsley can also be added for additional aroma.
Step-by-Step Instructions
Step 1 – Prepare the Lamb
Remove the rack of lamb from the refrigerator about 20 minutes before cooking. Allowing the meat to come closer to room temperature helps it cook evenly.
Pat the lamb dry with paper towels. This step helps the seasoning stick and allows the meat to roast properly.
Season the rack of lamb generously with kosher salt, black pepper, garlic powder, onion powder, and chicken stock powder. Rub the seasoning evenly over the meat.
Step 2 – Prepare the Roasting Pan
Preheat your oven to 425°F (220°C).
Spread the whole garlic cloves across the bottom of a roasting pan or oven-safe skillet. Place a few sprigs of fresh thyme on top of the garlic.
Position the rack of lamb on top of the garlic and herbs with the fat side facing upward.
Step 3 – Add Butter and Roast
Place the diced butter evenly over the rack of lamb.
Transfer the pan to the oven and roast the garlic roasted rack of lamb for 20–25 minutes.
Cooking times may vary depending on the size of the rack and your preferred doneness:
- Rare: 125°F (52°C)
- Medium-rare: 130–135°F (54–57°C)
- Medium: 140°F (60°C)
Using a meat thermometer is the most reliable way to achieve perfect results.
Step 4 – Rest the Lamb
Once the lamb reaches your desired internal temperature, remove it from the oven.
Let the garlic roasted rack of lamb rest for 10 minutes before slicing. Resting allows the juices to redistribute and keeps the meat tender.
Step 5 – Prepare the Butter Sauce
While the lamb rests, prepare the butter sauce.
In a small bowl, combine:
- Melted butter
- Lemon juice and zest
- Minced garlic
- Dijon mustard
- Chopped parsley
- Chives
- Thyme
- Paprika
- Cayenne pepper
- Salt and black pepper
Whisk everything together until smooth.
Step 6 – Slice and Serve
Place the rested rack of lamb on a cutting board.
Use a sharp knife to cut between the ribs to create individual lamb chops.
Serve the garlic roasted rack of lamb with roasted garlic cloves and drizzle the butter sauce over the top or serve it on the side.
