A dinner soup needs enough in the bowl to count as dinner. This tomato-and-bean pot uses canned beans so the cooking time is clear; dry beans need their own preparation and cannot simply replace canned beans in a short simmer.
Make one pot for about four bowls
Gather one diced onion, two chopped carrots, one 14-ounce can of diced tomatoes, two drained and rinsed 15-ounce cans of beans, and three cups of water or broth. A little oil, salt and pepper are optional. In a pot, soften the onion and carrot in oil over medium heat for about five minutes. If you are skipping oil, add a splash of water and stir so the vegetables do not catch. Add tomatoes and water or broth; simmer until the carrots are tender. Stir in the canned beans and simmer until hot throughout. Taste before adding salt, especially if the cans or broth are already seasoned.
For a thicker soup, mash some beans against the side of the pot. For a brighter finish, add a little vinegar or lemon if it is already in the kitchen. Bread, cooked rice or a simple salad can make a small bowl a larger meal. Do not call a thin vegetable broth a full dinner for four without checking what else is being served.
Cut the carrots into similar pieces so they become tender together. If the onion begins to stick, reduce the heat and add a little water rather than scorching it to meet the five-minute estimate. Taste a carrot before declaring the pot ready. Canned beans are already cooked, but they still need to be heated through in the soup. Stir the bottom as the soup thickens so mashed beans do not catch.
For a family of four with large appetites, four bowls may be small. Plan bread, rice or another side before shopping, or increase the pot size. For two people, portion the next meal before serving seconds. The recipe gives a starting yield so you can adjust, not a guarantee that one can per two diners suits every household.
Red lentils when the beans are gone
If you have dry red lentils instead of canned beans, make a separate pot rather than dropping them into the recipe above. Rinse one cup of red lentils, then simmer them with a diced onion, two chopped carrots, a 14-ounce can of tomatoes and about four cups of water or broth. Stir and check the liquid as they soften; add more water if the bottom begins to catch. Follow the lentil package for cooking time and cook until the lentils are tender. This makes roughly four bowls, depending on how thick you serve it. Taste at the end, especially if the broth contains salt. Bread or rice can stretch the meal.
Red lentils tend to soften into the liquid, so this version will be smoother than the bean pot. If you want distinct pieces, add some vegetables later in the simmer after the lentils have begun to soften. A thicker soup may need extra water when reheated. Do not substitute an unfamiliar dry bean for the lentils and keep the same time; dry beans vary and some need special preparation for safety.
Use leftovers deliberately
If the pot makes more than you need, ladle the extra into shallow containers and refrigerate it promptly. USDA advises keeping cooked leftovers three to four days in the refrigerator and reheating them to 165°F (74°C). Freeze a portion sooner if it will not be eaten in that window. A big pot left on the stove to cool overnight is unsafe; smell cannot tell you whether a leftover is safe.
Next time, change the vegetable or seasoning according to what is available. Cabbage works in place of carrots, and a spoon of tomato paste can deepen a plain broth. Keep the canned-bean method as the known starting point; if you switch to dry beans, follow their package directions and allow the extra cooking time. That is a different recipe, even if the finished bowl looks similar.
Before changing several ingredients at once, make the basic pot once and note what it needs in your kitchen: more vegetable, a different bean, less liquid or a side. Check labels for sodium if that matters to your household. A can of tomatoes, two cans of beans and a few vegetables can be a dependable pantry dinner, but its value comes from being cooked safely and sized for the people eating.
For packed lunch, keep the chilled soup cold until reheating. A container that seals well avoids a spill but does not replace temperature control. Reheat until hot throughout and to the leftover target cited above. Label the date so a second serving does not become a mystery bowl at the back of the refrigerator.
Adjust thickness after the beans are tender
Wait until the main ingredients have finished cooking before deciding that the soup is too thick or thin. Beans, lentils and pasta continue to absorb liquid, especially during storage. Add a small measured amount of liquid, stir and let the pot return to an even temperature before changing it again.
Write down the pot size, canned or cooked bean amount and final yield. On the next batch, that note helps you scale the liquid without relying on the fill line of a different pot. When reheating a thick portion, stir carefully and check the center because the edges can become hot first.
