This vibrant root vegetable tagine is a celebration of Moroccan-inspired flavours, bringing together the natural sweetness of carrots and sweet potatoes with the earthy depth of turnips. A homemade spice blend of toasted cumin, coriander and caraway seeds provides a punchy, aromatic base, while sun-dried tomatoes and green olives add a salty, umami kick.

How to make Root Vegetable Tagine with Sweet Potatoes, Carrots, Turnips, and Spice-Roasted Chickpeas
Toast coriander, cumin, and caraway seeds in small skillet over medium heat until beginning to brown, about 2 minutes. Cool. Transfer to spice mill; process until finely ground. Transfer to small bowl. Add red pepper, turmeric, and 1/2 teaspoons salt.
Mix lemon slices, lemon juice, and 4 teaspoons coarse salt in small skillet. Bring to boil. Reduce heat, cover, and simmer until lemon slices are almost tender, about 10 minutes. Cool preserved lemon. Drain and chop. DO AHEAD: Spice blend and preserved lemon can be made 1 week ahead. Store spice blend airtight at room temperature. Transfer preserved lemon to small bowl; cover and chill.
Heat olive oil in heavy large pot over medium-high heat. Add onion; sprinkle with salt and sauté until beginning to soften, about 5 minutes. Add toasted spice blend, garlic, and tomato paste; stir 1 minute. Add carrots and celery; stir 2 minutes. Add chopped preserved lemon, 950ml water, sweet potatoes, turnips, olives, and sun-dried tomatoes. Simmer with lid ajar until vegetables are tender, stirring occasionally, about 35 minutes. Stir in parsley, coriander, and mint. Season to taste with salt and pepper. Remove from heat and let stand 10 minutes to allow flavours to blend.
Spoon couscous into large bowl, spreading out to edges and leaving well in centre. Spoon vegetable tagine into well in centre. Sprinkle Spice-Roasted Chickpeas over and serve.
