How to Make It
Preheat oven to 375°F. Stir together flour, sugar, beer, and 4 tablespoons of the butter until mostly smooth; spoon batter into a lightly greased 9- x 5-inch loaf pan. Drizzle remaining 2 tablespoons butter over batter. Bake in preheated oven until golden brown, 45 to 50 minutes. Cool in pan 5 minutes. Remove bread from pan; transfer to a wire rack to cool at least 20 minutes before cutting into 1/2-inch-thick slices.
Heat olive oil in a Dutch oven over medium-high. Add onion; cook, stirring occasionally, until tender, about 4 minutes. Stir in garlic and dill; cook until fragrant, about 30 seconds. Add vegetable soup mix, chicken stock, tomatoes, pepper, and, if desired, Parmesan rind. Bring to a simmer; reduce heat to medium-low, and cook, stirring occasionally, until vegetables are tender, 10 to 15 minutes. Remove Parmesan rind, if used, and divide soup among 6 bowls. Top each with 1 tablespoon pesto; serve with bread.
