“Roasting removes excess water before the tomatoes ever meet the pot.”
Canned tomato soup is cheap and tastes like it. Roasting real tomatoes first drives off the water that makes them taste raw and thin, and chickpeas give the pot enough body that no cream is needed. It runs about an hour, most of it unattended while the oven works.
Preheating the pan is the difference between roasted and stewed. Tomatoes laid cut side down on already-hot metal sear where they touch instead of sitting in their released juice for the first ten minutes. If yours come out pale and swimming at 425°F (220°C), the pan went in cold. Scrape every sticky brown patch into the pot.
🍅 The promise: roasted-tomato depth out of an hour that is mostly oven time, thickened by chickpeas rather than cream.


Every sticky brown patch left on the sheet pan is concentrated tomato, so scrape the pan into the pot rather than rinsing it.
Balsamic and torn basil go in with the heat off, and four minutes of resting is what lets the vinegar settle into the tomato instead of sitting on top.
Heat the oven to 425°F (220°C) with a rimmed metal sheet pan inside for 8 minutes. The tomatoes need contact with hot metal to caramelize instead of stewing in their own juice.

Toss 2 lb (907 g) quartered ripe Roma tomatoes, 1 yellow onion (180 g) in wedges, and 6 peeled garlic cloves (30 g) with 2 tablespoons (30 ml) olive oil, ¾ teaspoon (4.5 g) kosher salt, and ½ teaspoon (1 g) black pepper. Roast cut side down 28 to 32 minutes, until browned and collapsed.

Meanwhile simmer 2 cans (425 g each) rinsed chickpeas with 3 cups (720 ml) low-sodium vegetable broth, 1 teaspoon (1 g) dried oregano, the remaining 1 tablespoon (15 ml) olive oil, and the remaining salt in a soup pot for 10 minutes.

Scrape the roasted vegetables and every drop of their juices into the pot, since the sticky brown patches on the pan carry most of the flavor. Blend until mostly smooth, leaving a few chickpea flecks for body.

Simmer uncovered 5 to 8 minutes, stirring frequently so the thick base does not catch on the bottom. It is ready when the soup coats the back of a spoon and a finger leaves a clean stripe.

Take the pot off the heat, stir in 1 tablespoon (15 ml) balsamic vinegar, and tear ¼ cup (15 g) fresh basil into it. Rest 4 minutes before tasting, letting the vinegar settle into the tomato.

The tomatoes taste sweet rather than raw, the chickpea skins have vanished into the body, and the soup leaves a clean trail on a spoon. If the soup tastes thin rather than sweet, the answer is more time in the uncovered simmer, not more salt.
Lay every tomato cut face flat against the preheated metal so its sugars brown; pieces resting on skin will only stew.
