Reasons to Love this Rack of Lamb in Oven Recipe
Because sometimes chicken just won't cut it.
Your great-grandmother didn't serve boneless, skinless chicken breasts at Sunday dinner, so why should you?
Rack of lamb is tender, juicy (when cooked right), and downright show-stopping with way less effort than it looks.
You'll look like you spent all day in the kitchen (when really, you didn't).
This is the kind of recipe that once you taste it, you'll wonder why lamb isn't already on your regular meal rotation.
Ingredients for Roasted Rack of Lamb
- Rack of lamb - you'll want 3 pounds of lamb, about 2 racks, frenched. Ask your butcher for frenched racks (cleaned bones) for the best presentation and easy carving.
- Olive oil - this helps the herb mixture to stick to the lamb and keeps it juicy as it roasts.
- Aromatics - fresh garlic is best for bold flavor but all the fresh herbs, like parsley, thyme, and rosemary balance out the fat content. A touch of citrus in lemon zest and juice brightens the dish.
- Seasonings - a simple blend of sea salt and black pepper is enough to bring out all the flavors.
Make it Ancestral
Lamb is almost always grass-fed since sheep naturally graze, making it one of the most nutrient-dense meats you can choose. Rich in protein, B12, zinc, and healthy fats, it's an elegant cut that stays tru to ancestral eating.

Step 1. Mix
In a small bowl, mix together olive oil with minced garlic, parsley, rosemary, thyme, lemon zest, and sea salt until a paste forms.
Step 2. Spread
Place the lamb in a baking pan, fat side up. Spread the herb garlic mixture generously over all over the lamb rack but keep the focus on top.
Step 3. Roast
Roast the rack of lamb in the preheated oven for 20-25 minutes for medium-rare. Tent loosely with foil and rest for 10 minutes before slicing.
Step 4. Carve
Carve between the bones to create chops. Serve warm.
Helpful Tips
- Start with frenched racks - look for lamb racks that are "frenched" meaning the rib bones are cleaned of meat and fat for a more elegant presentation and easier slicing. Most butchers will do this for you if you ask.
- Bring to room temperature - pull the lamb out of the fridge 30-60 minutes before roasting to ensure even cooking.
- Use a meat thermometer - for medium-rare, remove the lamb when the internal temp hits 125–130°F. It will continue to rise with residual heat.
- Fat side up - Always roast with the fat side facing up so the fat bastes the meat as it cooks.
Troubleshooting
- Herb paste slides off? This happens and is totally okay but you do want to make sure the lamb is patted completely dry with paper towels before applying the olive oil herb mixture.
