Ingredients needed

• Lamb: The star of the dish. Rich, tender, and flavorful, it becomes incredibly juicy when slow-roasted and soaks up all of the spices beautifully.
• Red onion – The onion caramelizes into soft, sweet ribbons that balance the savory elements and deepen the dish’s flavor.
• Carrots – Their natural sweetness intensifies in the oven, adding color, texture, and a hint of caramelization.
• 1 large tomato – Juicy and slightly acidic, the tomato breaks down into a rich, savory base that helps tie all the flavors together.
• Salt & pepper – Simple but essential. Salt enhances all the natural flavors, while black pepper adds subtle warmth and depth.
• Other seasonings (Italian seasoning, paprika, oregano) – The perfect trifecta of spices that complements the sweetness of the roasted veggies and the earthiness of the lamb
• Walnuts – Add unexpected crunch and a toasty, nutty flavor that contrasts beautifully with the tender meat and soft vegetables.
• Vegetable stock – Keeps everything moist during baking, creating a light, flavorful broth at the bottom of the pan that’s perfect for spooning over each serving.
• Fresh parsley (for garnish) – For a bright pop of color and a clean, herbal note to finish the dish!

How to make roasted lamb & veggies

You’ll do some of the prep work to start out the dish, then the oven will do the rest for you! Here are the steps to make this delicious meal.

• Cut and season the meat: Rub salt, pepper, Italian seasoning, and paprika on the lamb, and finish off with some olive oil.
• Prepare the veggies: Cut all of the vegetables and then arrange in an oven-safe baking dish in an even layer. Add in the vegetable stock, 1 cup of walnuts, salt, pepper, and oregano.
• Cook the lamb: Heat a pan with olive oil over medium-high heat and cook the meat until browned all over, about 2 minutes on each side.
• Put everything together: Nestle the cooked meat into the baking dish with the veggies. Then cover with aluminum foil and bake in the oven for 90 minutes.

Tips on making this recipe

• Let the lamb come to room temperature — Take the lamb out of the fridge about 30 minutes before cooking. This helps it cook more evenly and prevents toughness.
• Don’t skimp on seasoning —Lamb really shines with bold flavors. Generously coat the meat with the spices and rub it in to create a flavorful crust.
• Cut veggies evenly — Slice carrots and red onion into similar-sized pieces so that they roast evenly. Thicker chunks will hold up better to the long baking time.
• Cover, then uncover —Cover the dish with foil for the first part of baking to lock in moisture, then uncover it near the end to allow the top to brown and caramelize.
