Ingredients Needed
This recipe is made with simple, accessible ingredients that balance flavor and texture perfectly. Here’s what you’ll need:
For the Tomato Soup
- 1 tablespoon olive oil – Helps sauté the onion and garlic, adding a smooth richness to the soup.
- 1 small onion, chopped – Adds sweetness and depth of flavor as it cooks down.
- 2 cloves garlic, minced – Brings aromatic flavor that enhances the tomatoes.
- 1 can (28 oz) crushed tomatoes – The base of the soup. Crushed tomatoes create a smooth yet slightly textured consistency.
- 2 cups vegetable broth – Provides body and flavor while keeping the soup vegetarian.
- 1 teaspoon sugar – Balances the natural acidity of the tomatoes for a smoother taste.
- ¼ cup heavy cream (optional) – Adds creaminess and richness; you can omit for a lighter soup or replace with coconut milk for a dairy-free version.
- Salt and black pepper, to taste – Essential for seasoning and balancing flavors.
For the Grilled Cheese Croutons
- 4 slices bread – White, sourdough, or whole wheat all work. Choose a sturdy bread so the croutons stay crispy.
- 4 slices cheese – Cheddar, American, provolone, or a mix; use what melts well and suits your taste.
- 2 tablespoons butter – Softened, for spreading on the bread to create a golden, crisp crust when grilled.
Step-by-Step Instructions
Follow these detailed steps for the best results:
Step 1: Prepare the Tomato Soup
- Heat the oil – In a large pot, heat 1 tablespoon of olive oil over medium heat.
- Cook onion and garlic – Add the chopped onion and sauté for 4–5 minutes until it softens and turns slightly golden. Add the minced garlic and cook for another 1 minute, stirring to prevent burning.
- Add tomatoes and broth – Stir in the crushed tomatoes and vegetable broth. Mix well to combine.
- Balance flavors – Add 1 teaspoon of sugar to cut acidity, then season lightly with salt and pepper.
- Simmer – Bring the soup to a gentle boil, then reduce heat to low. Simmer uncovered for 15 minutes, stirring occasionally, to allow flavors to meld.
- Blend (optional) – For a smooth soup, use an immersion blender directly in the pot or transfer to a blender in batches. If you prefer a chunkier texture, leave it unblended.
- Add cream – Stir in the heavy cream if using, then taste and adjust seasoning with more salt and pepper if needed.
Step 2: Make the Grilled Cheese Croutons
- Assemble sandwiches – Butter one side of each bread slice. Place a slice of cheese between two bread slices, keeping the buttered sides facing out. Repeat to make two sandwiches.
- Grill sandwiches – Heat a skillet over medium heat. Cook each sandwich for about 2–3 minutes per side, until the bread is golden brown and the cheese has melted.
- Cool and cut – Remove from the skillet, let the sandwiches cool slightly, then cut them into bite-sized cubes to create croutons.
Step 3: Serve the Soup
- Ladle and top – Pour hot tomato soup into bowls.
- Add croutons – Top each bowl with grilled cheese croutons just before serving to keep them crisp.
- Enjoy – Serve immediately while hot.
Tips for Success
- Use high-quality canned tomatoes (San Marzano for the best flavor).
- Add red pepper flakes for a hint of spice.
- Make it vegan by using plant-based butter, cheese, and cream.
- For extra flavor, sprinkle the croutons with garlic powder before grilling.
