How to Make a Memorable Roast Dinner
Step 1: Roast the Garlic
Preheat oven to 400°F (205°C). Place peeled garlic cloves and 1½ tablespoons olive oil with a pinch of salt in a foil pouch. Roast for about 30 minutes until fork-tender and golden. Mash the garlic to a paste.

Step 2: Prep the Herb Paste
Mash together the roasted garlic, remaining olive oil, minced tarragon, thyme, chives, salt, and pepper until you have a thick, fragrant paste.
Step 3: Season the Lamb
Let the lamb racks sit at room temperature for 30 minutes. Pat dry, season with salt and pepper, then rub the garlic-herb paste all over.

Step 4: Roast the Lamb
Increase oven to 425°F (220°C). Place lamb racks, fat side up, on a roasting pan or rimmed baking sheet. Roast for 5 minutes, then lower oven to 375°F (190°C).
Continue roasting until the internal temperature is:
- 130°F (54°C) for medium-rare (about 10–12 minutes)
- 135–140°F (57–60°C) for medium (about 14–16 minutes)
Remove from oven, tent with foil, and let rest for 10 minutes before slicing.
Step 5: Slice and Serve
Cut lamb into individual chops or double chops. Serve with mashed potatoes, green beans, and your favorite sides.


Tips for the Best Roast Dinner
- Roast garlic ahead: This step can be done days in advance and stored in the fridge.
- Let the meat rest: This ensures juicy, tender lamb.
- Use a thermometer: Doneness is all about temperature, not just time.
- Serve with classic sides: Mashed potatoes, roasted veggies, buttered green beans, or a crisp salad.

Storage & Reheating
- Leftover lamb: Store in an airtight container in the fridge up to 3 days.
- To reheat: Warm gently in the oven, covered with foil, or slice cold for sandwiches and salads.
Serving Ideas
- Creamy mashed potatoes, buttered green beans, roasted potatoes, asparagus, or broccolini.
- Add a simple pan sauce or a drizzle of olive oil and lemon.
- For a festive touch, serve with cranberry chutney or mint jelly.
