Kate Hudson’s rustic tomato soup is made by roasting halved Roma tomatoes, then simmering them with softened onion and broth before puréeing until smooth. The Kitchn’s review describes the method and quantities; its suggested oven temperature—375°F—is a reviewer recommendation, not a temperature specified by Hudson’s TikTok tutorial.
What goes into Kate Hudson’s tomato soup?
The Kitchn’s January 20, 2025 review describes a simple base of eight Roma tomatoes, one diced onion, and about one cup of chicken or vegetable broth. Olive oil and flaky sea salt are also used in preparing the tomatoes and onion. Fresh basil and a drizzle of olive oil are optional finishing touches.
The “4-ingredient” label needs a little context: the review presents the core ingredients alongside oil and salt used in the method, with basil and finishing oil as garnish. It does not establish an independently verified yield. The Kitchn’s review links to Hudson’s TikTok tutorial.
How to make the soup
- Roast the tomatoes. Halve eight Roma tomatoes and arrange them on an oiled baking sheet. Brush them with olive oil and season generously with flaky sea salt. The Kitchn reviewer recommends roasting at 375°F for about an hour, until the tomatoes burst and their edges caramelize; the review says the tutorial itself does not specify a temperature.
- Soften the onion. Dice one onion and sauté it in olive oil until soft and translucent.
- Combine and crush. Add the roasted tomatoes to the onion and cook for a few more minutes. Gently crush the mixture with a potato masher.
- Add broth and simmer. Pour in about one cup of chicken or vegetable broth, then bring the soup to a gentle simmer.
- Purée until smooth. Blend with an immersion blender, or transfer the soup to a regular blender and purée it smooth. Finish with fresh basil and a drizzle of olive oil if desired.
How long does it take?
The Kitchn reviewer estimates less than three minutes of initial preparation, about an hour to roast the tomatoes, and another five to ten minutes for cooking, mashing, and blending. Treat these as the review’s estimates rather than guaranteed timings; roasting time can depend on the tomatoes and oven.

Do you need a blender?
Yes, if you want the smooth texture described in the review. An immersion blender lets you purée the soup in the pot; a regular blender is also given as an alternative. A potato masher helps crush the tomatoes before blending but does not replace the blender for a smooth finish.
Serving ideas and optional variations
The review notes that Hudson serves the soup with grilled cheese. For the basic version, basil and a little olive oil are suggested as toppings. The Kitchn also lists optional additions such as chili crisp, Parmesan, oregano, cayenne, za’atar, rosemary, cream or coconut milk, and lemon juice. These are variations, not part of the basic method.
