2. In a 2-quart rectangular baking dish, stir together onion, carrot, broth, and garlic. Top with fish fillets, tucking under any thin edges. Spinkle with kosher salt, paprika and pepper. Top with asparagus.
3. Bake, covered, for 15 - 20 minutes or until fish flakes easily when tested with a fork. Serve fish with vegetables.
