Slow Cooker Beef and Lentil Stew

3.5 stars from 20 ratings of Slow Cooker Beef and Lentil Stew

The lowly lentil has had a rise in popularity recently with the introduction of the Slow Carb Diet by Tim Ferriss who wrote the book 4 Hour Body. Tim maintains that a legume should be eaten at every meal (about 30% of the plate) , and lentils are an easy staple. He has tried many diets, and feels this is a good ratio to stick with for maximum weight loss. After reading his book, it is evident that he has basically donated his body to science while still living in it!

Lentils are an often overlooked, very inexpensive ingredient that can be used to stretch a meal. Compared to other dry legumes, lentils cook up quickly, and are very versatile flavor wise. Canned lentils can be substituted for dry, just make sure they are well drained and rinsed.

They are relatively low calorie, but pack a lot of nutrition. Studies show adding fiber to your diet can lower cholesterol, and the folate and magnesium in lentils are heart healthy. They digest slowly, which helps to prevent spikes in blood glucose, and gives the feeling of fullness for a longer period of time. Lentils are about 25% protein, which helps in the building of all body tissue, particularly muscle.

This stew cooks in the slow cooker, and makes the whole house smell wonderful. It can be turned into a soup by adding more beef broth, if that is desired. The dry lentils are added in the last hour of cooking, and can be turned up to high if you find your stew doesn't simmer on low in your crock pot. If no one is available to add the lentils, then substitute with canned lentils and just stir until heated through just before serving.

This meal also freezes well for another day. Goes great with warm crusty bread, of course only if you are not doing the Slow Carb Diet! Enjoy!

        Sunshine625 thank you for looking. Yes, lentils are one of those foods that taste good hot like this stew, or cold in a salad. I love adding more broth to this recipe to turn it into a soup.

        Pstraubie48, I agree, doing the prep ahead of time, and letting the slowcooker work all day is a treat. The whole house smells great too!

        Just Ask Susan, and Peggy W, thank you for kindly pinning this recipe for easy look up. Hope you give it a try.

        Purple Peach, my apologies for the quality of the photos! I need to improve in that area.

        Marilyn Fritz, congratulations on your weight loss. Legumes are getting more press time lately. Dr Joel Fuhrman counts lentils in his supper immunity foods.

        DaphneDL, thank you for looking!

        Oh my goodness! My husband and I love Lentil soup, but this recipe is a winner! I am going to give it a try next week. We have lost weight by consuming legumes often, so we can relate to the importance of having them often. We generally feel healthier, and have more energy. I love how you itemized your information, great writing!
