This hearty slow cooker vegetable stew is ideal for chilly fall and winter days. It combines root vegetables and savory aromatics for a warming, nutritious meal that’s easy to prepare and perfect for meal prep.
With just a few minutes of chopping, you can combine the ingredients in a slow cooker and let them simmer until tender. The long, gentle cooking time develops deep, comforting flavors while the vegetables become melt-in-your-mouth soft.

The flavor is savory with a subtle sweetness from winter squash and root vegetables. This low-fat, nutrient-dense stew is full of fiber, vitamins and satisfying texture. It’s excellent for batch cooking — keep it in the refrigerator for up to five days or freeze portions for longer storage.
Make it as a main dish or serve it alongside grains, crusty bread or a green salad. For a heartier option, stir in cooked lentils or beans at the end of cooking. Leftovers taste even better after a day, when the flavors have had time to meld.

How to Make this Stovetop
Although this recipe is designed for the slow cooker so you can set it and forget it, you can easily adapt it to the stovetop. Combine the same ingredients in a large pot, bring to a gentle simmer, cover and cook for roughly 45–60 minutes until the vegetables are tender. If you want the same thickened finish, mix cornstarch or flour with a little water to make a slurry and stir it in during the last 5–10 minutes of cooking. Remove bay leaves before serving.
