This stew is savory, hearty and comforting with a hint of sweetness. It’s absolutely perfect after a long day, especially a cold one! It’s can be made ahead and kept in the fridge for up to 5 days, it can be frozen and it makes a great packed, plant-based lunch too.

The vegetables are cooked until perfectly soft and ready to melt-in-your-mouth with every bite. Best part? It’s so easy to make: just a few minutes of chopping, toss it all in the slow cooker and dinner will be ready in a few hours. I love the flavour of the slightly sweet butternut squash and parsnips with the carrots, rutabaga, onion and garlic.

Health Benefits of Root Vegetables

Butternut squash isn’t actually a root vegetable but parsnips, carrots and rutabaga are. Root vegetables are some of the most nutrient-dense foods in the world. They each have their own set healthy benefits but they also share some common ground, so to speak. Root vegetables are all high in antioxidants, vitamin C, B, A and iron and high in fiber with healthy carbohydrates making them a great source of energy

How to Make this Stovetop

The benefit for cooking this in a slow cooker is not having to worry about it for around 5-6 hours, plus giving it extra time for the flavours to come together and vegetables to cook to tender perfection. However, you can also make it on the stovetop.

I’d probably let it slightly simmer for about 45 minutes to an hour until everything is soft. Once it’s cooked, stir in the cornstarch or flour mixture, remove from heat and let it thicken up. Either way it will be delicious. I prefer the slow cooker method for this dish though.

Vegetable Options

You can go ahead and customize the vegetables in this stew. Still use the onion and garlic but the other vegetables can be mixed and matched with any of the following, up to 12 cups total:

  • sweet potato (regular, white or garnet)
  • yam
  • rutabaga
  • turnip
  • potato (any variety)
  • carrot
  • butternut squash
  • acorn squash

This hearty, filling stew is easy to make in a slow cooker with any combination of root vegetables. Use 12 cups total cubed veggies to customize to your liking. This stew is great for meal prep as the flavors only improve the next day. Freezes well too!


  • 1 28 oz can diced tomatoes, with their juices
  • 2 rutabagas, peeled and cubed (approx. 4 cups)
  • 1/2 a butternut squash, peeled and cubed (approx. 4 cups)
  • 3 carrots, peeled and chopped (approx. 2 cups)
  • 3 parsnips, peeled and chopped (approx. 2 cups)
  • 1 large or 2 small white onions, diced (approx. 2 cups)
  • 4 cloves garlic, minced
  • 1 cup vegetable stock
  • 1 tsp ground thyme
  • 2 bay leaves
  • 2 tbsp cornstarch or flour mixed with 2 tbsp of water
  • 1 tbsp pure maple syrup
  • salt and pepper, to taste


  1. Add all ingredients except for the cornstarch/flour to a slow cooker and give it a good stir to mix thoroughly.
  2. Cook for approximately 3-4 hours on high or 4-6 hours on low. When there’s about an hour left, combine the cornstarch or flour with a little water in a small bowl to form a paste then stir into the stew.
  3. Let simmer lightly on low for another hour or so. There’s no real set time for this, once the vegetables are soft and tender and it’s thickened up, it’s ready!
  4. Season with salt and pepper and serve right away or store in the fridge up to 5 days or freezer up to 3 months.


For the vegetables, you can use up to 12 cups of any combination the following: butternut squash, acorn squash, sweet potato or yam, potato (any variety), turnip, rutabaga, carrot.

This makes 5 large meal-sized servings of about 500 grams each. It could serve 6-7 in smaller portions but since it’s so low calorie, I like a large serving of this. Alternatively, you can mix in up to 2 cups of cooked lentils for a more substantial meal.
