Slow Cooker Beef and Lentil Soup is the perfect way to make a healthy and delicious one-pot meal the whole family is sure to love. In addition to beef stew meat and a heap of lentils, you’ll only need a few veggies and staple seasonings.

If you’re looking for a meatless option, you’ll enjoy my traditional Slow Cooker Lentil Soup.

Being part of the legume family, lentils are wonderful cooked up in the crockpot. I have found that one of the best ways to add flavor to lentils is to use stock (or broth) and the perfect amount of fresh herbs. This recipe brings in the flavors thanks to stew meat, beef stock, vegetables, and seasonings like chili flakes and fresh herbs.

This soup can be enjoyed any time of the year and is super easy to make. The prep time is quick and the cooking time can be as short as 4 hours when the crock pot is used on the high setting. The next time you’re looking for a quick and delicious meal, go for a pot of this beef and lentil soup! You may also like my slow cooker sausage lentil soup recipe.

Recipe Ingredients

• Beef Stew Meat: You can purchase this meat pre-diced or a chuck roast and cut it into small cubes.
• Dried Lentils: Make sure these are rinsed to remove the small rocks. Green lentils or brown lentils can be used.
• Vegetables: Carrots, celery, white onion, and kale (stems removed).
• Beef Stock: I prefer to use low-sodium but you can use regular beef stock or beef broth for this recipe. You can also use chicken broth or vegetable broth.
• Seasonings: Olive oil, garlic, fresh thyme, fresh rosemary, bay leaves, chili flakes (to taste), and salt.
