In some Indigenous communities, corn, beans and squash are known together as the Three Sisters, a name rooted in companion planting. This is a contemporary home soup, not a single prescribed Indigenous recipe: versions differ, and no one bowl represents every community. Here, butternut squash softens into the thyme broth while corn and kidney beans stay distinct for a hearty spoonful.

Step 1Wash the produce under cool running water. Dice the onion, carrots and celery; mince the garlic. Peel and seed the squash, then cut it into even 2–2.5 cm cubes.
Step 2Drain the canned kidney beans in a colander and rinse them under running water. Weigh 500 g after draining; use fully cooked canned beans, not raw or partly cooked beans.
Step 3Warm the canola oil in a large heavy pot over medium heat. Add the diced onion and cook for 2–3 minutes, stirring, until it begins to turn translucent.
Step 4Add the carrots and celery. Cook for 5–6 minutes, stirring often, until the vegetables begin to soften but still hold their shape.
Step 5Stir in the minced garlic and cook for about 30 seconds, just until fragrant; do not let it brown or scorch.
Step 6Pour in the vegetable broth and add the squash, dried thyme and bay leaf. Raise the heat and bring the liquid to a boil.
Step 7Cover the pot, reduce the heat to a gentle simmer and cook for 12–15 minutes. The squash should be easily pierced with a fork, while the carrots remain intact.
Step 8Press a few soft squash cubes against the side of the pot with a fork or masher, then stir them into the broth to give it a little body without puréeing the soup.
Step 9Add the frozen corn and rinsed kidney beans. Simmer uncovered for 5–7 minutes, stirring occasionally, until the corn and beans are piping hot.
Step 10Remove and discard the bay leaf. Stir in the measured salt and pepper, taste, and adjust only with the seasonings already listed; broth brands differ in saltiness.
Step 11Ladle the soup into eight bowls and serve hot. Keep the corn, beans and squash visible so the three main ingredients remain easy to recognize.
Step 12Refrigerate leftovers in shallow containers within 2 hours and keep them at or below 4°C; use within 2–3 days or freeze. Reheat soup to a full rolling boil while stirring, and check a portion reaches 74°C before serving.
Choose a firm squash that feels heavy for its size, and use low-sodium broth so the measured salt remains useful. Frozen corn and canned beans make this soup practical year-round; drain and rinse the beans before weighing. For a thicker bowl, mash a little more squash in the pot rather than adding flour or cream. The recipe is naturally plant-based when made with vegetable broth. Refrigerate leftovers within 2 hours in shallow containers, keep at or below 4°C, and use within 2–3 days or freeze.
Approximate ingredient-based estimate for one eighth of the batch, using reduced-sodium vegetable broth and drained, rinsed canned kidney beans. Brands, drained bean weight, produce size and salt retention vary; this is not laboratory analysis.
Celery is an ingredient. No priority allergen is intentionally added in the base recipe, but packaged broth and beans vary; check labels for gluten, soy and ingredients relevant to your allergies. Use clean equipment and prevent cross-contact.
Yes. Use the same measured weight of kernels cut from a cooked cob, or use drained canned corn. Stir it in with the beans and heat the soup until piping hot; label and sodium content can vary by product.
