Hearty Vegetable Lentil Stew with Potato Puree

Hearty Vegetable Lentil Stew with Potato Puree

Fall is in full swing now in the northern hemisphere and the temperatures are dropping. As the weather gets cooler we naturally begin to crave more hearty feeling and heavy foods. And this recipe for a vegetable lentil stew is perfect for a cool or cold night. Making you feel warm from the inside.

Cooking vegetable lentil stew

This vegetable lentil stew is super simple to make. The ingredients are basic and likely items you stock in your cabinet on a regular basis. Lentils cook much faster than other forms of legumes so this dinner won’t take any longer than one hour to prepare, most of it is cooking time allowing you to step away for a bit to do other tasks.

Save some time

Making vegetable lentil stew definitely takes no more than one hour to prepare from start to finish. But it’s also the perfect dish for a slow cooker or to meal prep.

Slow cooker

One of my favorite kitchen tools for saving time is the slow cooker and using the slow cooker is a great way to prepare this vegetable lentil stew. The total time to prep and get the items into the slow cooker is about 15-20 minutes.

To get started simply saute the vegetables in step one. Then add all the lentils, diced tomato and lentils as indicated in step two. Plus throw in the thyme and marjoram and program your slow cooker for two and a half hours to three hours.

When you are ready to serve up the dish, add the kale, salt and pepper and cook just long enough to wilt the kale, about 10 minutes.

Make the stew ahead

Lentil vegetable stew is also perfectly to making ahead when you have some free time. I recommend cooking the entire stew but wait to add the kale until the point when you reheat the dish for service. The kale loses more of its green color when it sits and is reheated.

If possible, make the potatoes at the time you want to serve. I think they are just better that way. But if you are really pressed for time and want to make ahead, you will need to add some milk or water to the potatoes to reheat.
