Ingredients Used to make Root Vegetable Lentil Stew

This recipe uses frozen vegetables and pre-cooked lentils, making it incredibly easy to prepare.

  • Olive oil – you can also use other plant oils like canola, sunflower, or coconut oil.
  • Onion and Garlic – sautéed for that perfect base of savory flavor with a touch of sweetness.
  • Vegetable broth + water – I added water instead of using pure broth to keep the stew from getting too salty as it reduces and thickens.
  • Tomato paste – gives the dish an appetizing color and a rich umami taste.
  • Herbs – I used thyme for its sharp, almost minty flavor to brighten up the dish and bay leaf to provide a layer of herbal, slightly floral aroma and taste. You can use other herbs like basil, oregano or sage. This rustic soup does not need too much though, a combination of two should be more than enough.

  • Frozen root veggies –  you can use a pack of assorted ones or chop some carrots, beets, potatoes, turnips, and radishes instead.
  • Other veggies – we also used frozen peas, celery and lentils to bulk it up. Feel free to add any other vegetables that you like. Cabbage, zucchini, cauliflower, broccoli, mushrooms, corn and green beans are great options!
  • Salt and pepper –  for seasoning.

Optional ingredients

  • Garlic powder, to taste
  • Cumin, to taste

Tips when Making Root Vegetable and Lentil Stew

  • Make it thicker. Use an immersion blender or stab mixer and blitz the mixture after simmering to make a thicker soup.
  • Keep the proportions the same.  If you are using fresh veggies, cut them all the same size.  This will ensure that they cook evenly and in around the same length of time.
  • Dice into small pieces. Getting every single ingredient into one spoonful is the best way to enjoy this dish.
  • Simmer using low heat. Do not let the mixture come to a boil or you will risk overcooking the vegetables and ending up with mushy veggies.
  • Add some kick! A pinch of red pepper flakes will give this vegan stew a touch of spiciness.

Make-ahead and Storage Notes

  • Make-Ahead. The flavors in this recipe develop over time, and it reheats beautifully! Double the recipe and store half of the stew divided into individual serving sizes to enjoy for the next few days! You can refrigerate it in an airtight container for up to 7 days.
  • In the freezer. This Root Vegetable Lentil Stew can be frozen for up to 3 months. Make sure to place it in a freezer-friendly bag or container and tag it with the storage date.
  • To Reheat. If frozen, thaw it overnight in the refrigerator before reheating in a saucepan over medium heat.  If it is too thick, add a splash of broth or water.  You can use salt or pepper to season it if needed.

Frequently Asked Questions

  • What type of lentils should I use? – I used green lentils in this recipe. However, you can also use brown or red lentils for this stew. If you’ve never made lentils before, this Guide to Lentils may be helpful!
  • Can I make this Root Vegetable and Lentil Stew in an Instant Pot? Absolutely! After sautéing, add the rest of the ingredients to the pot and press Manual or Pressure Cook and set the timer to 8 minutes on high pressure.
  • Can I make this stew creamy? If you prefer a creamier soup, then you can replace the water with coconut milk instead. Or you can just add a dollop of vegan sour cream or vegan yogurt before serving.
  • What’s the difference between stew and soup?  Soup is any liquid-cooked mixture of ingredients. Stew refers to any dish barely submerged in just enough liquid to cook the ingredients thoroughly at a low simmer in a covered pot for an extended period of time. So it’s just a matter of the amount of liquid you use that makes a difference.
