In the fall and winter, I always turn to soups for some warm, soothing meals – and this lentil vegetable soup with tarragon and thyme is delicious! It’s perfect for this time of year and can easily be made with seasonal vegetables and ingredients that you can keep stocked in your pantry, such as canned tomatoes, spices, and lentils. But no meat! This soup is actually vegan, so anybody can enjoy it! It’s great for those when you might otherwise turn to canned chicken noodle soup, but maybe it’s a “meatless Monday,” you want something homemade, or you just want something a little different! This recipe makes 8 servings, so it’s something that can last several meals or you can even freeze leftovers to reheat on another day.

This lentil vegetable soup uses tarragon and thyme to add delicious flavors, and like pretty much any herb, they have been linked to some health benefits. A lot of these benefits are hard to pinpoint to specific herbs, so we aren’t completely sure if they’re true. What we do know is that they make this soup taste delicious! Although the soup takes about 75 minutes to prepare and cook, a lot of the cooking time is just allowing it to simmer, so you have some time to relax or get something else done while it finished cooking. We love making recipes that aren’t totally hands-on!

We have plenty of other hearty soup recipes on our website, too! Some of our favorites include beef and sweet potato chili, corn zucchini chowder, and slow cooker chicken enchilada soup!
