Recipe Tips

• Use San Marzano tomatoes for the best flavor.
• Always add cream after blending to avoid curdling.
• If using a countertop blender, allow the soup to cool slightly before blending.
• For crispy croutons, let grilled cheese sandwiches rest for a few minutes before cutting.
• Add a pinch of smoked paprika for a deeper, smoky flavor.

Variations

• Vegan Version: Use coconut milk instead of cream and vegan cheese/butter for croutons.
• Roasted Tomato Soup: Roast fresh tomatoes and garlic before blending for a richer flavor.
• Spicy Kick: Add chili flakes, cayenne pepper, or hot sauce.
• Cheese Variations: Try gruyère, brie, or fontina for the grilled cheese.
• Low-Carb Option: Skip the croutons and serve with a side of roasted veggies.

Freezing and Storage

• Storage: Keep soup in an airtight container in the fridge for up to 4 days. Store croutons separately to avoid sogginess.
• Freezing: Freeze soup (without cream) for up to 2 months. Add cream when reheating.
• Reheating: Warm on the stovetop over low heat, stirring occasionally. For croutons, reheat in an oven or toaster for crispiness.

Special Equipment Needed
