Ingredients
Rack of Lamb
1 rack of lamb, Frenched, 1½–2 lbs (6–8 ribs), pasture-raised, grass-finished
2 tbsp extra virgin olive oil
1 tsp sea salt, ½ tsp freshly ground black pepper
2 tbsp quality French Dijon mustard (Maille or Fallot)
1 tsp Chinese five-spice powder (cinnamon, fennel, cloves, white pepper, star anise)
1 tbsp fresh rosemary, finely chopped
1 tbsp fresh thyme leaves
Zucchini Pasta
2 medium-large zucchini (about 1½ lbs total), spiralized
1 additional medium zucchini, cut into ¼-inch cubes
2 cups cherry tomatoes, halved (mixed colors if possible)
1 small shallot, finely minced
3 cloves garlic, minced
3 tbsp extra virgin olive oil (divided)
1 tbsp raw apple cider vinegar (or fresh lemon juice)
⅓ cup crumbled goat's milk feta or grated Parmigiano-Reggiano
Sea salt, freshly ground black pepper
Fresh basil or thyme, for garnish
Sub: freshly ground whole five-spice (cinnamon stick, fennel seeds, cloves, white peppercorns, star anise pods) is dramatically better than pre-ground — five-spice loses its volatile oils within weeks once ground.
Method
Remove the rack from the refrigerator 45 minutes before cooking. Room-temperature meat sears evenly; cold meat does not.
Preheat the oven to 400°F.
Season the lamb. Pat the rack completely dry. Combine Dijon, five-spice, rosemary, and thyme in a small bowl. Rub the rack all over with the olive oil, then season with salt and pepper. Spread the Dijon-herb mixture over the meat side only — leave the fat cap unadorned so it can crisp properly. Rest 10 minutes at room temperature.
Render the fat. Heat a heavy oven-safe skillet (cast iron is ideal) over medium heat. Place the rack fat-side down, bones up. This is the critical step and it takes 15 minutes — do not rush it. Do not move the meat. Let the fat render slowly, gradually increasing to medium-high in the final 5 minutes. The rendered fat will puddle around the rack. By 15 minutes the fat cap should be deeply mahogany, crisp, nearly black-brown in places. If still pale, give it 2–3 more minutes at medium-high.
Brief side sears. Turn the rack to sear the meat side (the Dijon side) for about 1 minute, just to set the mustard. Sear the ends 30 seconds each.
Finish in the oven. Transfer the skillet to the 400°F oven. Roast 8 minutes for medium-rare (130°F internal at the thickest part, not touching the bone). 10 minutes for medium (135°F). Use a thermometer — lamb's sweet spot is narrow.
Rest 10 minutes tented loosely with foil. Carryover cooking will bring the temperature up about 5°F.
Make the zucchini pasta while the lamb rests. In a wide skillet, heat 2 tbsp olive oil over medium-high. Add shallot and garlic; cook 30 seconds. Add cherry tomatoes cut-side down and cook undisturbed 2–3 minutes until they begin to blister. Add the cubed zucchini and cook 2–3 minutes more, stirring, until tender-crisp. Season with salt and pepper. Turn off the heat. Add the spiralized zucchini noodles and toss gently with the residual heat — it will soften them just enough without overcooking. Drizzle with the remaining tablespoon of olive oil and the vinegar. Toss.
Carve. Stand the rested rack upright and slice between the bones to separate into chops — one chop per rib, 6–8 total. The meat should be rosy throughout with a deeply crisp fat cap.
Plate. Arrange the zucchini pasta on a platter. Place the chops on top or alongside, bones angled upward. Scatter goat feta or shaved Parmigiano across the zucchini. Add fresh herb sprigs. Finish the lamb with flaky salt and a thread of your best olive oil.
Variations
With provençal herb rub instead of Chinese five-spice: Substitute the five-spice with 1 tsp dried herbes de Provence (rosemary, thyme, savory, marjoram, lavender). Pairs beautifully with the Dijon and feels more traditionally Provençal.
With Middle Eastern spice rub: Substitute the five-spice with 1 tsp ground sumac + ½ tsp ground cumin + ½ tsp ground coriander + ¼ tsp ground cinnamon. Serve with a side of fresh cucumber-mint salad and tahini drizzle.
With lamb chops (instead of a rack): Substitute with 8 single-rib lamb chops. Same Dijon-herb rub and fat-rendering technique. Reduce skillet rendering time to 8 minutes per side; skip the oven finish or oven-finish for 3–4 minutes.
With lamb loin or shoulder roast: Substitute with a 2-lb boneless lamb loin or shoulder roast. Use the same rub. For shoulder, increase oven time to 25–30 minutes at 375°F for medium.
With roasted baby potatoes: Serve the rack over a simple bed of arugula dressed with lemon and olive oil, with roasted baby potatoes in the rendered lamb fat on the side.
Seasonal vegetable swap (zucchini alternatives):
— Spring: asparagus + blanched fresh peas + fresh mint
— Late summer: spiralized yellow squash + roasted eggplant + fresh basil
— Autumn: spiralized butternut squash + sautéed kale + toasted hazelnuts
— Winter: roasted cauliflower florets + roasted parsnip + sage + lemon zest
Make ahead: The rack can be seasoned with the Dijon-herb rub and refrigerated up to 24 hours ahead. Bring to room temperature 45 minutes before cooking. The zucchini side should be made fresh — it doesn't hold well
Sourcing
Rack of lamb. Pasture-raised, grass-finished. D'Artagnan, Crowd Cow, Niman Ranch, Heritage Foods USA, or local farms via Eatwild.com. Ask the butcher to French the rack (cut between the bones, scrape clean, expose the bones). New Zealand and Australian grass-fed lamb is widely available and excellent.
French Dijon mustard. Authentic French Dijon — fermented, made with brown mustard seeds. Maille (the benchmark) or Fallot. Avoid American-style "Dijon" which lacks the fermented depth.
Chinese five-spice powder. Freshly ground whole spices (cinnamon stick, fennel seeds, cloves, white peppercorns, star anise pods) is dramatically better than pre-ground. Grind in a small spice grinder just before use. If buying pre-ground: Penzeys, The Spice House, or specialty Asian grocers.
Fresh rosemary and thyme. From a windowsill pot, farmers' market, or organic produce section.
Zucchini. Firm, glossy zucchini with bright green skin. Smaller zucchini have better flavor and fewer seeds. Italian heirloom varieties (Costata Romanesca) offer more flavor than standard varieties. Always keep the peel on — the lutein and zeaxanthin live there.
Cherry tomatoes. Mixed colors at a farmers' market in peak summer — Sungolds, Chocolate Cherries, Tomberries, or local heirloom varieties.
Goat's milk feta or Parmigiano-Reggiano. Greek PDO feta (sheep + goat milk) or French chèvre feta. For Parmigiano-Reggiano, look for the rind stamp indicating DOP designation (aged 24+ months ideally).
Raw apple cider vinegar. With the mother — Bragg's is the benchmark.
Extra-virgin olive oil. Single-estate, harvest-dated within the last 12 months, in a dark glass bottle. Italian or Spanish single-origin works beautifully.
Sea salt. Baja Gold mineral sea salt for cooking, fleur de sel for finishing.
Nourishment Notes
The fat-rendered rack is the technique that matters here. Grass-finished lamb fat carries fat-soluble vitamins A, D, E, and K2; provides stable saturated fat that supports mitochondrial function; and produces the specific crisp, sweet, almost-caramelized flavor that defines traditional roast lamb. Rendered lamb fat, like rendered duck fat, was historically saved as a cooking medium for other dishes — strain the 3–4 tablespoons of liquid gold that pool in the pan, refrigerate in a small jar, and use for roasting vegetables through the rest of the week. Pasture-raised, grass-finished lamb itself delivers complete protein, heme iron, zinc, B12, selenium, and conjugated linoleic acid in concentrations that exceed most muscle meats — and unlike beef, ground lamb at the supermarket still tends to come from animals raised on grass for most of their lives.
Chinese five-spice powder is worth a proper introduction because most readers have encountered it only in Chinese cooking. The blend — cinnamon, fennel, cloves, white pepper, and star anise — has been formalized in Chinese cuisine for at least 2,000 years, where the original framework was traditional Chinese medicine's wu xing (five-element) theory: each spice corresponds to one of five flavor elements (sweet, bitter, salty, sour, pungent), and the combination produces a balanced effect on the body. Whether or not one accepts the framework, the spices themselves are functionally remarkable: cinnamon (proanthocyanidins, glycemic support), fennel (digestive support, phytoestrogens), cloves (eugenol, one of the most antimicrobial compounds known), white pepper (piperine, enhances absorption of other spices), star anise (shikimic acid, antiviral). Real French Dijon, fermented and made with brown mustard seeds, carries isothiocyanates similar to those in radishes and brassicas — supporting liver phase-two detoxification.
As a seasonal food, lamb belongs to spring — across four thousand years of pastoral history, ewes have lambed in late winter and early spring, and the first young animals are ready to eat as the first warm evenings arrive. The zucchini side carries the late-spring/early-summer companion: zucchini is 95% water, rich in vitamin C, lutein, and zeaxanthin in the peel, low-glycemic, and hydrating — which keeps the rich lamb in balance. Always keep the peel on. Lycopene in cherry tomatoes becomes more bioavailable with brief charring, and the olive oil and goat feta supply the fat necessary for absorption. As a circadian food, lamb is a dense, fat-forward protein best metabolized during peak daylight — midday or early-evening dinners land cleanly while there is still significant light on the table; late-night lamb pushes the body's cooling and melatonin curve back.
Storage
Leftover sliced lamb keeps 2–3 days refrigerated. Cold, thinly sliced, it makes an exceptional next-day lunch over greens with a spoonful of the strained rendered fat warmed back into a quick vinaigrette. Leftover zucchini pasta does not keep well — eat it the day it's made or keep extra plain spiralized zucchini noodles in air-tight glass tupperware for about 2 days.
