Tomato soup
A thick, mild tomato soup with carrot, onion and potato, made with no-salt-added canned tomatoes and water, with no salt or ready-made stock. Blend it thick enough to load a spoon, with soft carrot sticks or toast strips to dip.

Ingredients
- 2 cans (400 g / 14 oz each)chopped tomatoesno salt added; check the label for added salt or sugar
- 2 mediumcarrots
- 1 mediumpotatoabout 200 g (7 oz); it thickens the soup
- 1onionfinely chopped
- 1 clovegarlicfinely minced, optional
- 4–5fresh basil leavesoptional, finely chopped
- 300 ml (1¼ cups)wateror homemade stock made without salt, with every bone piece strained out; not ready-made stock, which is usually salty
- 1 tbspolive or vegetable oil
Steps
- 1Wash your hands. Scrub the carrots under running water and peel them. Cut one lengthwise into sticks about 6–8 cm long and 2 cm wide (2½–3 × ¾ in), never round coins, for your baby to dip, and chop the other. Scrub the potato under running water, peel it, cut away any green, damaged or sprouting parts, and cut it into cubes about 2 cm (¾ in). Rinse and peel the onion, then chop it finely. If you use basil, rinse it under running water, pick the leaves off the stems and chop them finely.
- 2Heat the oil in a large pan over medium-low heat and cook the onion and chopped carrot gently for about 10 minutes, stirring, until soft. Add the garlic for the last minute, without letting it brown.
- 3Add the tomatoes, potato, carrot sticks and water. Bring to a boil, then cover and simmer gently for 20 to 25 minutes, until the potato and carrot fall apart when you press them with a spoon. Stir in the basil for the last 2 minutes. Don't add salt or stock. Before you blend, lift out the carrot sticks with a slotted spoon and squash one between your thumb and finger: it should flatten easily.
- 4Blend until completely smooth; for a baby of 9 months or older who manages lumps, you can scoop their portion out before blending and mash it instead. Take your baby's portion out now, before any salt or seasoning goes in. It should be thick enough to stay on a spoon when you tip it; if it's runny, simmer it uncovered for a few minutes.
- 5Spread your baby's portion in a shallow bowl to cool, stirring. Soup holds heat, so stir it well and check the temperature in the middle before serving: it should feel only just warm, never hot.
- 6For toast strips (once wheat has been introduced on its own), check the bread label. At every age, choose plain bread with no whole seeds, nut pieces or whole grain kernels; before 12 months, also check there's no honey (not safe under 12 months). Toast it lightly and cut it into strips about the size of an adult finger, roughly 6–8 cm long and 2 cm wide (2½–3 × ¾ in).
How to serve it by age
6 months+
Serve the soup thick, on a pre-loaded spoon your baby can hold, or let them scoop it up with their fingers. Offer the soft carrot sticks you set aside to dip, or toast strips once wheat has been introduced.
9 months+
Serve it thick, or mash some of the soft potato and carrot instead of blending, leaving soft lumps no bigger than about 1 cm (just under ½ inch). Chop the soft carrot sticks into pieces that size, not round coins, to stir in or pick up, and offer toast strips to dip.
12 months+
Serve it from the unsalted family pot in a bowl with a spoon, with toast strips or soft bread on the side. Keep it warm, not hot. Skip seeded crackers and chips: the CDC lists them as choking hazards for young children.
Where US and UK guidance differ on this recipe
United States(AAP and CDC)Your setting
The AAP says fresh baby food should be cooked with no added salt or seasoning, and that most vegetables should be cooked until soft for babies. It doesn't give an age for herbs or garlic. If you'd rather follow that closely, leave out the garlic and basil, or ask your pediatrician.
United Kingdom(NHS)Your setting
The NHS says not to add salt, stock cubes or gravy to your baby's food or cooking water, and not to give honey before 1 year. Its general salt advice suggests herbs, spices and garlic to add flavor instead of salt. If you use them, keep them finely chopped, cooked in and unsalted.

Leftovers and the rest of the family
Storing it
Cool leftovers quickly in shallow containers and keep them covered in the fridge for 3 to 4 days, or freeze them in small portions for 2 to 3 months. Don't keep leftover tomatoes in an opened can: move them to a covered container in the fridge. Thaw frozen soup in the fridge and eat it within 24 hours of thawing. Reheat only the portion you need, and only once, until steaming hot, 165°F (74°C), or bring it to a rolling boil, stirring so there are no hot or cold spots. Let it cool and check the temperature before serving. Throw away anything left in your baby's bowl, and any soup left out at room temperature for more than 2 hours (1 hour if it's hotter than 90°F / 32°C).

For the grown-ups
Take your baby's portion out first, then season the rest with salt, black pepper and a pinch of chili flakes for the adults, or stir in a splash of cream. Serve with grilled cheese sandwiches or crusty bread.
