Served piping hot with a golden-brown grilled cheese sandwich, classic tomato soup conjures up memories of the crisp fall days of our youth. Most of us probably enjoyed the canned stuff as kids, but making a flavorful tomato soup from scratch isn't much harder than opening a few cans of tomatoes, sautéing some aromatic vegetables, and blending it all together.

Canned Tomatoes Are Best

While fresh ripe summer tomatoes can make a lovely tomato soup, when it comes to mastering classic tomato soup, canned is best. Canned tomatoes provide a consistent soup whether you're making it October or January. You can use whole canned tomatoes or even canned diced tomatoes for making this soup in a pinch, but I've found crushed tomatoes have the right amount of acidity and flavor and don't require as much blending time.

Classic tomato soup also gets a potent dose of concentrated tomato flavor from tomato paste. While the amount is small, you really shouldn't skip or substitute this for any other tomato product. Keep both canned tomatoes and tomato paste on hand for tomato soup anytime.

Blend First, Then Cook

Blending hot soup is a deceptively tricky kitchen task. Whether you're trying to move hot soup into a blender jar or trying to get a smooth soup with an immersion blender, hot soup ends up splattered everywhere. Beyond being a mess, blending hot soup can also be a little dangerous. Instead, blend the tomatoes and sautéed aromatics before cooking. This step might seem unnatural at first, but sautéing the onions and garlic before blending it ensures the bite of those aromatics is cooked out without overcooking the soup.

On Flour

This recipe calls for a bit of flour to thicken the soup, but feel free to skip it if wheat is an issue for you. The soup won't thicken quite as well, but it will still be full of flavor.

What You Need


  • 4 tablespoons

    unsalted butter

  • 1

    large sweet onion, diced

  • 2 cloves

    garlic, coarsely chopped

  • 1/2 teaspoon

    kosher salt

  • 1/4 cup
