Frequently Asked Questions
Q: Can I substitute heavy cream with a lighter option?
A: Yes, you can substitute heavy cream with half-and-half, whole milk, or a non-dairy alternative like coconut milk or cashew cream. Keep in mind that using a lighter option may slightly change the soup's richness and creaminess.
Q: What if I don't have an immersion blender?
A: If you don’t have an immersion blender, you can carefully transfer the soup in batches to a regular blender. Be sure to let it cool slightly and avoid overfilling the blender to prevent splattering. Blend until smooth and return to the pot to reheat.
Q: Can I use fresh tomatoes instead of canned crushed tomatoes?
A: Yes, you can use fresh tomatoes. Substitute with about 6-7 medium fresh tomatoes, chopped. You may need to simmer the soup a bit longer to ensure the fresh tomatoes break down completely, or blanch and peel them beforehand for a smoother texture.
Q: How do I prevent my grilled cheese croutons from becoming soggy?
A: To keep the croutons crisp, add them to the soup just before serving. Alternatively, you can serve them on the side and let each person add them to their soup as they eat.
Q: Can I make the soup and grilled cheese croutons ahead of time?
A: Yes, the soup can be made up to 3 days in advance and stored in an airtight container in the refrigerator. Reheat on the stovetop over medium heat, stirring occasionally. For the grilled cheese croutons, it's best to prepare them fresh, but you can make the sandwiches ahead, refrigerate them, and reheat in the oven or skillet before cutting into croutons.
Q: What are some variations for this recipe?
A: You can add roasted red peppers or a pinch of smoked paprika for a smoky flavor, or stir in some fresh spinach or kale for added nutrients. For the grilled cheese, try experimenting with different cheeses like gouda, mozzarella, or pepper jack, or add a thin slice of tomato or a sprinkle of herbs for extra flavor.
Q: Can I freeze the soup?
A: Yes, the soup freezes well. Allow it to cool completely, then transfer to a freezer-safe container or bag. It can be frozen for up to 3 months. When reheating, thaw in the refrigerator overnight and warm on the stovetop. Note that the cream may separate slightly upon reheating, but stirring well can help re-incorporate it.
