For the Soup
• Whole Peeled Tomatoes – Use San Marzano for the best flavor and depth in your roasted tomato soup.

• Garlic – Essential for that aromatic taste; fresh garlic is preferred, but garlic powder can work in a pinch.
• Unsalted Butter – Gives richness to the soup; for a vegan option, olive oil is a great substitute.

Step‑by‑Step Instructions for Roasted Tomato Soup with Cheesy Crouton Topper
Step 1: Preheat and Combine
Start by preheating your oven to 425°F (220°C). In a large Dutch oven, mix together the whole peeled tomatoes, chopped yellow onion, minced garlic, fresh thyme, unsalted butter, a drizzle of olive oil, kosher salt, and black pepper. Stir until everything is well combined, and the aroma fills your kitchen, enticing everyone around!
Step 2: Roast the Mixture
Transfer the Dutch oven to the preheated oven and roast uncovered for 40–45 minutes. Watch as the tomatoes soften and bubble, transforming into a rich sauce with caramelized edges. The colors will deepen and the flavors intensify, creating a fragrant base for your Roasted Tomato Soup that’s worth the wait.
Step 3: Prepare Cheesy Croutons
While the tomatoes are roasting, tear sourdough bread into bite-sized pieces for your croutons. Toss the pieces with melted butter and Italian seasoning in a mixing bowl. Spread the seasoned bread on a baking sheet, then bake in the same oven for 13–15 minutes, or until they turn golden brown and crispy, adding delightful texture to your soup.
Step 4: Blend the Soup
Once the tomatoes are perfectly roasted, carefully remove the Dutch oven from the oven and stir in vegetable broth. Allow the soup to simmer on the stovetop for an additional 10 minutes. Using an immersion blender, purée the mixture until it’s incredibly smooth and velvety, transforming it into the comforting Roasted Tomato Soup you crave.
Step 5: Cheese and Broil
Ladle the luscious soup into bowls, then top each serving generously with sharp cheddar cheese and the crispy croutons. Place the bowls under the broiler for about 2 minutes, keeping a close eye on them. Look for the cheese to bubble and begin to turn golden, creating a deliciously gooey topping for your soup.
Step 6: Garnish and Serve
To finish, sprinkle fresh thyme leaves over the top of each bowl for a burst of color and flavor. Serve your hearty Roasted Tomato Soup with Cheesy Crouton Topper alongside a warm, crusty bread for a comforting meal that’s perfect for gathering friends and family around the table.

Roasted Tomato Soup with Cheesy Crouton Topper Recipe FAQs
What type of tomatoes should I choose for my soup?
Absolutely! For the best depth of flavor, I highly recommend using San Marzano whole peeled tomatoes. They’re sweet, juicy, and perfect for roasting, giving your soup that rich taste we all love. If San Marzano tomatoes are not available, look for high-quality canned tomatoes, ideally with no added preservatives.
How should I store leftover Roasted Tomato Soup?
Very simply! Allow your soup to cool completely before transferring it to an airtight container. It will keep well in the fridge for up to 5 days. Just pop it in the fridge and enjoy a warm bowl on a busy weekday!
Can I freeze Roasted Tomato Soup?
Of course! This soup freezes beautifully. I suggest portioning it into freezer-safe bags or containers, leaving a bit of space for expansion. It can stay in the freezer for up to 3 months. When you’re ready to enjoy it, thaw it overnight in the fridge and reheat gently on the stovetop.
What can I do if my soup is too acidic?
If you find that your soup is a bit too tangy for your taste, you can soften the acidity by adding a pinch of sugar or honey. Start with about a teaspoon, stir it in, and taste. Adjust as needed! Also, make sure to season after blending; flavors can change with cooking.
Are there any dietary considerations I should be aware of?
When preparing this Roasted Tomato Soup, always check your ingredients if allergies are a concern. Both the cheese and croutons can be substituted with vegan options for a dairy-free version, and ensure any broth used aligns with your dietary needs too. If serving to pets, remember that garlic and onions, which are safe for humans in small amounts, can be toxic to dogs and cats.
How do I know when my garlic is cooked perfectly?
Keep your eyes on it! You want your garlic to become fragrant and soft, which takes about 5-7 minutes on medium heat. If it starts to brown, reduce the heat immediately! Burnt garlic can introduce an unpleasant bitterness to your delicious Roasted Tomato Soup.
