This version of Tomato Soup Gratinée, takes the American classic Tomato Soup and Grilled Cheese combo to a whole new level. Creamy tomato soup topped with grilled baguette and mozzarella - gratinéed in the oven like a French Onion Soup Gratinée. The best of both worlds that you need to try now. The cheese pull is incredible.
Few things are as comforting as a rich tomato soup on a rainy day. Adding basil pesto (or fresh basil if it is in season) to the soup at the last minute brings a brightness to the dish that harkens Provence.
You will find this soup quick and easy to throw together and the cooking skill required for this recipe is very minimal. For me, Tomato Soup is a quick meal so while I appreciate the effort involved, I rarely roast the tomatoes in advance and prefer to use canned crushed tomatoes, especially if it is not tomato season. This soup can be ready in under 30 minutes.
Tips for making Simple Tomato Pesto Soup
- Allow your onions and garlic to soften in the olive oil at medium heat with the thyme. This will add a delicious richness to the soup
- I like to add a couple carrots for extra nutrients ( a habit formed while feeding a toddler!) They also bring a little sweetness to the soup.
- Add the cream and the basil at the very end, just before mixing.
- For the baguette slices, rub both sides with garlic before browning, it brings so much more flavor to each bite.
- Make as many baguette slices as you can fit in your pan - they are highly addictive!
Equipment Needed:
Soup Pot or Dutch Oven with at least 8 QT capacity (I love my Le Creuset Stock Pot or Dutch Oven for this soup)
Immersion blender (like this one by Kitchen Aid) or else a blender that you can pour the soup into.
French Onion Soup crocks. I like the traditional lion head bowls like you find in a French Bistro these but also a hearty handled version would be practical too. These white handled bowls would be easier to handle and are so cute.
Stainless Steel Sizzling Platters are so much easier to handle than a cookie sheet when making Tomato Soup Gratinée. You can fit 2 Soup Crocks at a time and the platters don't bend or warp like a cookie sheet can. A warped cookie sheet can be very dangerous when you have 4 bowls of steaming Tomato Soup on it! I use my sizzling platters for everything from finishing a steak in the oven to making grilled cheese to reheating a croissant.
How to Serve:
I like to serve my Tomato Soup Gratinée piping hot, especially on a rainy day! You will also make a double batch of the soup and freeze the leftovers. This soup can be kept for months in the freezer, ready for you to heat up whenever the inspiration strikes.
FAQ
This recipe is wonderfully fast — ready in under 30 minutes. Using good-quality canned tomatoes gives you deep, bright flavor without needing to roast fresh tomatoes. It’s the perfect comforting weeknight dinner.
Absolutely. Simply swap the chicken stock for vegetable stock. The soup remains rich with tomatoes, basil, garlic, onions, and carrots, and the cheesy gratinée topping still delivers all the indulgence.
Tomato Soup Gratinée elevates the classic tomato-soup-and-grilled-cheese pairing with a touch of French elegance. A creamy tomato-basil soup is topped with garlic-rubbed baguette slices and a generous layer of melted mozzarella, then broiled until golden and bubbling. Cozy, rustic, and oh-so-satisfying.
