Garlic, shrimp and white wine are three ingredients that practically beg to be served together. Roast vegetables at high heat and toss them with couscous for a quick, classic dinner.
Cook couscous - (Skip if already made for Tuesday’s meal.) Combine stock, salt and butter in a saucepan. Cover and bring to boil. Remove from heat. Stir in couscous and cover with lid. Let stand for ~5 minutes before fluffing with a fork. (Can be done up to 5 days ahead)
Toss onions, parsnips and sweet potatoes in cooking oil. Season with cumin and some salt and pepper and spread on a sheet pan. Cover tightly with foil and ‘steam’ in oven for 10 minutes. After 10 minutes, remove the foil and continue roasting until golden and tender, 10 to 12 minutes more. (For tips, check out this video on roasting vegetables at high temps.)
Heat a skillet with butter over medium heat. When butter melts, add tomato paste and wine and bring to a simmer.
Add shrimp with marinade and saute in white wine until cooked through, 3 to 5 minutes.
If couscous was made ahead, reheat briefly in the microwave.
Toss couscous with roasted vegetables.
Serve shrimp over couscous with a dollop of yogurt and lemon wedges on the side. Enjoy!
