Method
 

  1. Start by chopping the onions into small pieces and slicing the carrots into thin rounds. Set them aside, ready for sautéing and slow cooking.
  2. Heat a small amount of oil in a skillet over medium heat. Add the diced onions and cook for about 3-4 minutes until they turn translucent and smell sweet, with a slight caramelization around the edges.
  3. Transfer the sautéed onions to the slow cooker. Add in the sliced carrots, chopped celery, zucchini chunks, diced tomatoes with juices, and vegetable broth. Toss in a sprig of thyme and a bay leaf, then season with salt and pepper.
  4. Cover the slow cooker and set it to low. Let everything simmer gently for 6 to 8 hours, until the vegetables are tender and the flavors meld. You’ll notice the broth thickening slightly and the aroma filling your kitchen.
  5. After cooking, remove the bay leaf and thyme sprig. Taste the soup and adjust the seasoning with more salt, pepper, or a squeeze of lemon if desired.
  6. Serve the soup hot in bowls, garnished with fresh herbs if you like. The soup should be thick, vibrant, and filled with tender vegetables—perfect for a cozy, nourishing meal.

Notes

Feel free to add greens like kale or spinach near the end for extra freshness. This soup is very forgiving—toss in whatever vegetables you have on hand.
