Why choose between tomato soup and grilled cheese when you can have both in one bowl? This Tomato Cheddar Soup takes the beloved pairing to the next level by melting sharp cheddar directly into rich, velvety tomato soup. It's indulgent, it's comforting, and it's absolutely irresistible. Top it with grilled cheese croutons for the complete experience.
Why This Recipe Works
The key to perfect tomato cheddar soup is achieving that silky, cheesy texture without the cheese becoming stringy or separated. Using sharp cheddar adds tangy depth that pairs beautifully with the acidic tomatoes. The Worcestershire sauce is a secret weapon—it adds umami complexity that makes the soup taste more sophisticated without anyone being able to identify it.
The Art of Cheese Incorporation
Successfully adding cheese to hot soup requires patience and the right technique. First, reduce the heat—cheese that hits boiling liquid will seize up and become rubbery. Add the shredded cheese gradually, a handful at a time, stirring constantly until each addition is completely melted before adding more. Pre-shredded cheese from the store contains anti-caking agents that can affect texture, so shredding your own block cheese yields the smoothest results.
Step-by-Step Guide
Build your flavor base by sautéing onion until soft and sweet, then add the garlic just until fragrant. The tomatoes and broth simmer together to meld flavors before blending to your preferred smoothness. Some people like it completely smooth; others prefer a bit of texture.
The magic happens when you add the cheese. Drop the heat to low, then add the cheddar slowly. Keep stirring—this is not the time to multitask. Once all the cheese is incorporated and silky, finish with cream for extra richness.
Grilled Cheese Croutons
These are the crowning glory of this soup. Simply make your favorite grilled cheese sandwich, then cut it into bite-sized cubes. Float them on top of each bowl just before serving. They add crunch, cheese pull, and make this soup a complete meal. Kids especially love fishing them out.

Frequently Asked Questions
What cheese is best for tomato soup?
Sharp cheddar is the classic choice, offering tangy flavor that complements tomatoes. Extra-sharp adds even more punch. Gruyère, Monterey Jack, or a combination also work beautifully.
How do I prevent the cheese from getting stringy?
The key is low heat and patience. Reduce heat before adding cheese, add it gradually, and stir constantly. Pre-shredding the cheese helps it melt evenly. Never boil once cheese is added.
Can I make tomato cheddar soup ahead of time?
Make the tomato base ahead and refrigerate up to 3 days. Add the cheese when reheating—cheese doesn't reheat as well once it's been incorporated. Use low heat and stir constantly.
What are grilled cheese croutons?
These are small cubes of grilled cheese sandwich cut and served as croutons. Make a regular grilled cheese, then cut into 1-inch squares. They add texture and make the soup a complete meal.
Why add Worcestershire sauce?
Worcestershire adds umami depth that enhances both the tomato and cheese flavors. It's a secret ingredient that makes the soup taste more complex without being identifiable.
