Step‑by‑Step Instructions for Roasted Tomato Soup with Cheesy Crouton Topper
Step 1: Prepare Tomatoes
Preheat your oven to 425°F (220°C). In a large Dutch oven, mix together the whole peeled tomatoes, diced yellow onion, minced garlic, fresh thyme, unsalted butter, olive oil, kosher salt, and black pepper. Stir well until all the ingredients are evenly combined and the tomatoes are coated; this will create a flavorful base for your roasted tomato soup.
Step 2: Roast
Place the Dutch oven in the preheated oven and roast uncovered for 40–45 minutes. Keep an eye on the mixture as it cooks; the tomatoes should soften, bubble, and caramelize slightly. You’ll know it’s ready when the onions are translucent and the whole mixture is aromatic and deliciously fragrant, filling your kitchen with warmth.
Step 3: Make Croutons
While the tomatoes are roasting, tear the sourdough bread into bite-sized pieces. In a small bowl, toss the torn bread with melted butter and Italian seasoning until evenly coated. Spread the croutons out on a baking sheet and bake in the oven for 13–15 minutes, or until they are golden brown and crispy. These cheesy croutons will be the perfect topping for your soup.
Step 4: Blend Soup
Once the tomatoes and onions have roasted to perfection, carefully remove the pot from the oven. Stir in vegetable broth and bring the mixture to a simmer over medium heat for about 10 minutes. After simmering, use an immersion blender to purée the soup until it is completely smooth. This process will enhance the creamy texture of your Roasted Tomato Soup.
Step 5: Broil
Ladle the blended soup into bowls and generously top each serving with shredded sharp cheddar cheese and your crispy croutons. Sprinkle a little grated Parmesan on top for extra flavor, then place the bowls under the broiler for about 2 minutes. Keep a close watch; the cheese should melt and begin to bubble, adding a delightful layer of yumminess.
Step 6: Garnish
Before serving, garnish your Roasted Tomato Soup with a sprinkle of fresh thyme leaves for an added touch of freshness and color. This final step will elevate the dish, bringing a delightful herbaceous note to your comforting bowl of soup, ready to be savored on a chilly night.
Expert Tips for Roasted Tomato Soup
Perfect Tomatoes: Always use high-quality, whole peeled tomatoes like San Marzano for the richest flavor in your Roasted Tomato Soup.
Adjust Seasoning: Taste your soup before serving; the acidity of canned tomatoes can vary, so be ready to adjust salt and pepper as needed.
Garlic Perfection: For the best flavor, ensure your garlic becomes soft and fragrant during roasting. Avoid burning, as it can turn bitter.
Blend with Care: When puréeing hot soup, let it cool slightly to prevent splatters. An immersion blender is safer and easier for this step!
Crispy Croutons: Keep an eye on your croutons while they bake—oven temperatures can vary, and you want them golden, not burnt.
Add a Twist: Experiment with different cheeses for the topping; substituting Gruyère can give your Roasted Tomato Soup a more intense flavor.
How to Store and Freeze Roasted Tomato Soup
Fridge: Store leftovers in an airtight container for up to 5 days; this will help maintain the flavor and freshness of your delicious roasted tomato soup.
Freezer: If you want to save your soup for later, freeze it in airtight containers or freezer bags for up to 3 months. Allow soup to cool completely before freezing.
Reheating: For a quick meal, reheat on the stovetop over medium heat until warmed through, or microwave in short intervals, stirring to prevent hot spots.
Airtight Storage: Always ensure your container is airtight to avoid freezer burn and preserve the creamy texture of your soup after freezing.
