Made this for my elderly parents' anniversary. The slow-simmered depth made the soup feel luxurious, and the basil really brightened it up. They haven't stopped raving about it!

This soup transformed my dinner table! The heirloom tomatoes gave it such a deep, sweet flavor, and the fresh basil was a perfect finishing touch. My kids even asked for it as a side with their grilled cheese.
- ★★★★☆
Loved the recipe overall, but the simmering time was longer than expected (took 2.5 hours instead of 1.5). Next time I'll reduce the heat to avoid overcooking the tomatoes.
