Easiest Tomato Soup Recipe – Creamy 30-Minute Comfort

This easiest tomato soup starts with canned whole tomatoes and finishes in 30 minutes flat. You get a silky, bright bowl that tastes like it simmered all afternoon.

The trick is butter and a real char on the onion. Both build body without cream, so the soup stays tomato-forward instead of tasting like a milkshake.

Blend it smooth or leave it rustic. Either way, taste for salt at the end, because canned tomatoes vary wildly in sodium. Get the pan hot and trust the process.

About the Ingredients

4 tablespoons (56g) unsalted butter

Butter builds the silky body here. Swap in olive oil for a dairy-free version, but add 1 extra tablespoon since oil lacks butter's emulsifiers.

1 large yellow onion (about 300g), thinly sliced

Yellow onion gives sweetness without bite. Sweet onions work but need 1 less minute of sautéing; skip red onion, it turns the soup purple and sharp.

4 garlic cloves, smashed and peeled

Smashed cloves release flavor without burning. Use 1 teaspoon garlic paste if you are out, added off the heat so it does not scorch.

2 tablespoons (30g) tomato paste

Tomato paste is the umami anchor. Buy it in a tube, not a can, so you can use 2 tablespoons and not waste the rest.

2 cans (28 oz / 800g each) whole peeled tomatoes, with juice

Whole peeled San Marzano-style tomatoes crush into a thicker soup than diced. If you only have diced, simmer 8 extra minutes to concentrate them.

2 cups (480ml) low-sodium chicken or vegetable broth

Low-sodium broth keeps you in control of salt. Water plus 1 teaspoon Better Than Bouillon is a solid backup.

1 teaspoon kosher salt, plus more to taste

Kosher salt dissolves evenly and seasons gradually. If using fine table salt, start with 3/4 teaspoon; it is much denser.

1/2 teaspoon black pepper

Fresh-cracked pepper blooms in the butter. Pre-ground works but add it with the tomatoes instead, since it needs heat to open up.

1 teaspoon granulated sugar

Sugar balances acidic canned tomatoes. Taste first, then add; ripe summer tomatoes may need none at all.

1/4 cup (10g) fresh basil leaves, plus more to serve

Basil goes in off the heat so it stays green and fragrant. Dried basil is a fine swap: use 1 teaspoon with the tomatoes.

1/4 cup (60ml) heavy cream, optional

Cream is optional but rounds out the acidity. For dairy-free, stir in 2 tablespoons coconut cream at the end.

Tips & Tricks

• Do not boil after blending. High heat after pureeing breaks the emulsion and turns the soup grainy; keep it at a bare simmer.
• Vent the blender lid. Hot soup in a sealed blender builds pressure and pops the top; remove the center cap and cover it with a folded towel.
• Salt at the end, not the start. Canned tomatoes carry hidden sodium, so taste after blending and adjust then.
• Crush the tomatoes by hand. Squeezing them through your fingers gives better texture than a machine and lets you spot any tough cores.

Step-by-Step Instructions

1. Melt the butter

Melt the butter in a heavy Dutch oven over medium heat until it foams but does not brown, about 2 minutes at 300F (150C).

2. Brown the onion

Add the sliced onion and cook 8 to 10 minutes at 325F (165C) equivalent medium-low heat, stirring every 2 minutes, until the edges are golden brown and the onion slumps. Do not let it blacken; burnt edges turn the whole pot bitter.

3. Bloom the garlic and paste

Add the garlic and tomato paste and cook 60 to 90 seconds, until the paste darkens to brick red and smells sweet rather than raw.

4. Add tomatoes and broth

Crush the tomatoes by hand into the pot, add their juice, the broth, salt, pepper, and sugar. Bring to a simmer, 200F (93C) at the surface, with small bubbles at the edges.

5. Simmer to concentrate

Simmer uncovered 20 minutes at 200F (93C), stirring occasionally, until the liquid reduces by about a quarter and the soup coats the back of a spoon.

6. Blend until silky

Off the heat, add the basil, then blend with an immersion blender 60 to 90 seconds until completely smooth. If using a countertop blender, fill it halfway and vent the lid.

7. Finish and season

Stir in the cream if using, then taste and adjust salt. The soup should taste bright first, then sweet, with no raw tomato edge.

8. Serve hot

Ladle into bowls at 165F (74C) or hotter, top with torn basil, and serve with grilled cheese.

Delicious Variations

Roasted Red Pepper

Blend in 1 cup of jarred roasted red peppers with the basil for a smoky, sweeter bowl.

Spicy Vodka Style

Add 1/4 teaspoon red pepper flakes with the garlic and 2 tablespoons vodka with the tomatoes.

Creamy Basil Pesto

Skip the cream and swirl 2 tablespoons of pesto into each bowl at serving.
