The grilled cheese and tomato soup combination is arguably the most perfect food pairing ever created. There's something almost magical about dunking a crispy, golden, oozing grilled cheese into a bowl of warm, velvety tomato soup.
This recipe elevates both components beyond the basics β a three-cheese blend on sourdough with caramelized onions, paired with a rich roasted tomato soup that's leagues ahead of anything from a can.

The Three-Cheese Blend
Sharp cheddar for flavor, GruyΓ¨re for nuttiness and stretch, and fontina for supreme meltability. This combination delivers maximum flavor with maximum ooze. Ask at your deli counter for thinly sliced cheese β it melts more evenly than thick slices.
The Low-and-Slow Method
The biggest mistake people make is cooking grilled cheese over too-high heat β you get burnt bread and cold cheese. Medium-low heat, patience, and a lid or foil cover are the secrets. The lid traps steam, ensuring the cheese melts before the bread burns.
The Perfect Dipping Soup
Our regular tomato basil soup is the ideal companion. Make it slightly thicker for better sandwich-dunking consistency by reducing liquid slightly or adding less broth.
