Herb-Crusted Rack of Lamb with Greens

Jump to Recipe

Rack of lamb looks like a project. It’s not.

The cut is naturally tender and cooks fast. A simple crust of fresh herbs, garlic, and breadcrumbs, bound with Dijon mustard, does most of the work for you. You press it on, roast it hot, and rest it briefly. That’s the whole thing.

I add a quick pan of wilted greens, spinach or Swiss chard, to keep it balanced. The lamb is rich. The greens cut right through that.

This works for a weeknight dinner where you want to put in some effort, or for a small dinner party where you want the plate to look like you really tried. Either way, it’s real food doing its thing.

• Dijon mustard crust seals in juices naturally
• One pan for the lamb, one skillet for the greens
• Impressive plating with minimal actual effort

Ingredient Notes

• Rack of lamb (frenched): Ask your butcher to french the bones, which means scraping the rib bones clean. It makes carving cleaner and presentation sharper. Two racks of 8 ribs each will serve four comfortably.
• Dijon mustard: Acts as the glue that holds the herb crust to the lamb. Whole-grain mustard works too and adds a slightly coarser texture.
• Fresh breadcrumbs: Pulse day-old sourdough or white bread in a food processor. Fresh crumbs stick better and brown more evenly than dried. Panko works in a pinch but gives a slightly airier crust.
• Fresh rosemary and thyme: Fresh herbs give the crust a brighter flavor. Dried herbs can substitute at half the quantity if that’s what you have.
• Garlic: Finely mince or grate the garlic so it blends into the crust without burning in the oven. Garlic powder can stand in, use about half a teaspoon.
• Greens (spinach or Swiss chard): Both wilt quickly in a hot pan with olive oil and garlic. Baby spinach is fastest. Swiss chard has more body and a slightly earthier flavor.

Ingredients

  

For the herb crust

• 60 g fresh breadcrumbs from about 2 slices day-old sourdough
• 1 tbsp fresh rosemary, finely chopped
• 1 tbsp fresh thyme leaves
• 2 garlic cloves, finely minced
• 2 tbsp flat-leaf parsley, finely chopped
• 2 tbsp olive oil
• 0.5 tsp fine sea salt
• 0.25 tsp black pepper

For the lamb

• 2 frenched racks of lamb (8 ribs each) about 700-750 g each
• 2 tbsp Dijon mustard
• 1 tbsp olive oil for searing
• 1 tsp fine sea salt
• 0.5 tsp black pepper

For the wilted greens

• 300 g baby spinach or Swiss chard, roughly chopped
• 2 garlic cloves, thinly sliced
• 1 tbsp olive oil
• 1 tbsp lemon juice
• 0.25 tsp fine sea salt
• 1 pinch red pepper flakes optional

Method

 

Prepare the lamb and oven

1. Heat the oven to 220 C / 430 F. Take the lamb racks out of the fridge 20 minutes before cooking and pat them completely dry with paper towels.
2. Season the lamb generously on all sides with salt and black pepper.

Make the herb crust

1. Combine the breadcrumbs, rosemary, thyme, parsley, garlic, olive oil, salt, and pepper in a small bowl. Stir until the breadcrumbs are evenly coated in oil and the herbs are well distributed.

Sear the lamb

1. Heat 1 tbsp olive oil in a 10-inch oven-safe cast iron skillet over high heat until the oil just begins to smoke.
2. Place the lamb racks fat-side down in the skillet. Sear for 2 to 3 minutes until deep golden brown, then sear the other sides briefly, about 1 minute each, to build color.
3. Remove the skillet from the heat. Transfer the lamb racks to a wire rack set over a baking sheet, bone-side down.

Crust and roast

1. Brush the fat side of each rack with 1 tbsp of Dijon mustard, covering the top and sides evenly.
2. Press the herb breadcrumb mixture firmly onto the mustard-coated surface of each rack, creating an even layer.
3. Roast in the preheated oven for 18 to 20 minutes, until the crust is deep golden and an instant-read thermometer inserted into the thickest part reads 57 C / 135 F for medium-rare.
4. Transfer the racks to a cutting board and rest for 8 minutes without cutting.

Wilt the greens

1. While the lamb rests, heat 1 tbsp olive oil in the same cast iron skillet over medium heat. Add the sliced garlic and cook for 30 seconds until fragrant but not browned.
2. Add the spinach or chard and toss with tongs for 1 to 2 minutes until wilted and bright green.
3. Add the lemon juice, salt, and a pinch of red pepper flakes if using. Toss once more and remove from heat.

Carve and serve

1. Slice between the bones to separate the rack into individual chops. Arrange 2 to 3 chops per plate alongside a portion of the wilted greens. Spoon any pan juices over the lamb before serving.

Notes

If your lamb racks are smaller (6 ribs), reduce roasting time to 14 to 16 minutes and start checking the temperature at the 13-minute mark.

Tips for Success

• Pat the lamb racks completely dry before searing to get a proper brown crust on the outside.
• Sear the lamb fat-side down in a hot oven-safe skillet for 2 to 3 minutes before adding the herb crust.
• Press the breadcrumb mixture firmly onto the mustard-coated lamb so the crust adheres through roasting.
• Use an instant-read thermometer and pull the lamb at 57 C / 135 F for a rosy medium-rare center.
• Rest the lamb on a cutting board for at least 8 minutes before slicing between the bones.

Variations

• Swap breadcrumbs for finely ground pistachios to make a nut-crusted rack with a richer, slightly sweet finish.
• Add lemon zest and fresh mint to the herb mix for a brighter, more Mediterranean-leaning crust profile.
• Replace wilted greens with roasted cherry tomatoes and white beans for a heartier one-pan side.

Storage and Reheating

Store leftover lamb chops in an airtight container in the fridge for up to 3 days. Keep the greens separate so they don’t make the crust soggy.

To reheat, place the lamb on a wire rack over a baking sheet in a 150 C / 300 F oven for 10 to 12 minutes. Avoid the microwave as it makes the crust soft and the meat rubbery.

The greens reheat fine in a hot skillet with a splash of water or olive oil for about 2 minutes.

Serving Suggestions

Slice the rack between the bones into individual chops and arrange them leaning against each other on the plate. Pile the wilted greens alongside. A spoonful of pan juices over the top is all the sauce you need.

For a fuller spread, add roasted garlic herb potatoes or a simple lemon-dressed grain like farro or couscous. Both sit well next to the richness of the lamb, much like a hearty roasted squash farro bowl would on a larger spread.

A glass of Syrah or Côtes du Rhône works with the herb crust. If you want something lighter, a dry rosé from Provence holds up fine too.

FAQ

How do I know when herb-crusted rack of lamb is done without cutting into it?

Use an instant-read thermometer inserted into the thickest part of the meat, avoiding the bone. Pull it at 57 C / 135 F for medium-rare. The crust should be deep golden and the meat will feel slightly springy when pressed.

Can I use dried herbs instead of fresh for the breadcrumb crust on rack of lamb?

Yes, but reduce the quantity by about half since dried herbs are more concentrated. The crust texture will be similar but the flavor slightly less bright and grassy.

Can I apply the herb crust to the lamb the night before?

You can press the crust on up to 4 hours ahead and keep the rack uncovered in the fridge. Any longer and the moisture from the mustard softens the breadcrumbs. Sear just before roasting.

What greens pair best with herb-crusted rack of lamb?

Baby spinach wilts fastest and has a mild flavor that doesn’t compete with the herb crust. Swiss chard, cavolo nero, or even blanched broccolini all work and add more texture to the plate.

Is rack of lamb gluten-free if I skip the breadcrumbs?

The lamb and greens themselves are naturally gluten-free. To keep the crust, swap regular breadcrumbs for certified gluten-free breadcrumbs or finely ground almond flour. The texture will be slightly denser but still holds.

What is the difference between a frenched rack of lamb and a regular rack?

Frenching means the rib bones are scraped clean of meat and fat, which gives a cleaner presentation and prevents the exposed bone from burning in the oven. Most butchers will do this for you on request at no extra cost.
