The beauty of this stew lies in its simplicity – tender chicken thighs that practically fall apart, earthy lentils that provide substance and protein, and a medley of vegetables that make this a complete meal in one pot. Unlike many slow cooker recipes that require extensive prep work, this one truly lives up to its "easy" promise. On Sunday evenings, I spend about 15 minutes throwing everything into the slow cooker, set it on low, and wake up Monday morning to several days' worth of lunches and dinners. The leftovers taste even better as the flavors meld together, making this a meal prepper's dream.

Ingredients You'll Need
This stew relies on humble ingredients that transform into something extraordinary through slow cooking. Let's break down each component so you can shop with confidence and understand why each ingredient matters.
Chicken Thighs (2 pounds): I always use boneless, skinless chicken thighs because they stay incredibly tender during the long cooking process. Unlike chicken breasts, thighs won't dry out, even after 8 hours in the slow cooker. If you prefer, you can use bone-in thighs – just remove the bones before serving and add an extra 30 minutes to the cooking time. For a vegetarian version, substitute with 2 cans of chickpeas or white beans.
Brown or Green Lentils (1½ cups): These varieties hold their shape beautifully during cooking, unlike red lentils which would turn to mush. Lentils are nutritional powerhouses – packed with fiber, protein, and essential minerals. They don't require pre-soaking, making this recipe even simpler. If you're new to lentils, look for them in the dried beans section of your grocery store.
Mirepoix Mixture (2 cups): The classic combination of onions, carrots, and celery creates the aromatic base of this stew. I like to buy pre-diced vegetables when I'm really pressed for time, but cutting them yourself takes only about 5 minutes. Keep the pieces roughly the same size so they cook evenly.
Garlic (4 cloves): Fresh garlic adds a wonderful depth of flavor. I know it's tempting to use pre-minced garlic, but fresh really does make a difference here. If you must use jarred, reduce the amount by half as it's typically more potent.
Chicken Broth (6 cups): Low-sodium broth lets you control the salt level. Homemade broth would be amazing here, but store-bought works perfectly. For a vegetarian version, simply substitute with vegetable broth.
Diced Tomatoes (28 oz can): Fire-roasted tomatoes add an extra layer of smoky flavor, but regular diced tomatoes work wonderfully too. Don't drain them – the juice adds body to the stew.
Herbs and Spices: A blend of thyme, rosemary, and bay leaves gives this stew its signature flavor. These herbs complement the earthiness of the lentils without overwhelming the dish. Fresh herbs would be lovely, but dried are more practical for slow cooking.
How to Make Easy Slow Cooker Chicken and Lentil Stew
Prep Your Slow Cooker
Start by giving your slow cooker insert a quick spray with non-stick cooking spray or lightly coat with olive oil. This prevents sticking and makes cleanup a breeze. If your slow cooker has a removable insert, you can actually prep this the night before, cover it, and store it in the refrigerator until morning.
Layer the Vegetables
Add your diced onions, carrots, and celery to the bottom of the slow cooker. These vegetables create a natural base for the chicken and help prevent the lentils from sticking to the bottom. Season them with a pinch of salt and pepper – this builds flavor from the very beginning.
Add Lentils and Garlic
Rinse your lentils under cold water in a fine-mesh strainer, checking for any small stones or debris. Add the rinsed lentils and minced garlic on top of the vegetables. Don't stir yet – we're building layers of flavor. The lentils should stay above the liquid line for now to prevent them from becoming mushy.
Season the Chicken
Pat your chicken thighs dry with paper towels – this helps them brown slightly even in the slow cooker. Season both sides generously with salt, pepper, and half of your herbs. Don't be shy with the seasoning; the long cooking process can dull flavors, so we're building them up from the start.
Add Broth and Tomatoes
Pour in the chicken broth and add the entire can of diced tomatoes (with juice). The liquid should just cover all the ingredients – if it doesn't, add a bit more broth or water. At this point, you can gently press down on the ingredients to submerge them, but don't stir vigorously as we want to maintain those layers.
Add Final Seasonings
Sprinkle the remaining herbs and your bay leaves on top. Add a splash of Worcestershire sauce if using – it adds incredible depth without being detectable. Give everything one gentle stir around the edges, being careful not to disturb the bottom layer too much.
Set and Forget
Cover with the lid and cook on LOW for 7-8 hours or HIGH for 4-5 hours. Resist the urge to lift the lid during cooking – every time you do, you add 15-20 minutes to the cooking time. The stew is done when the chicken shreds easily with a fork and the lentils are tender but not mushy.
Final Adjustments
Once done, remove the bay leaves and taste for seasoning. The stew might need more salt depending on your broth. For a thicker consistency, remove the lid and cook on HIGH for 30 minutes. For a thinner stew, simply add more broth. Serve hot with crusty bread and garnish with fresh parsley if desired.
Expert Tips
Timing is Everything
Start with dried lentils, not canned or pre-cooked. Canned lentils will turn to mush during the long cooking process. If you must use canned, add them only in the last 30 minutes of cooking.
Temperature Matters
Always cook on LOW if possible. The gentle heat allows flavors to develop more fully and ensures the chicken stays incredibly tender. HIGH works in a pinch, but LOW is worth the wait.
Liquid Gold
If your stew is too thin, mix 2 tablespoons of flour with 1/4 cup of cold water and stir it in during the last 30 minutes. For a gluten-free option, use cornstarch instead.
Make-Ahead Magic
Prep everything the night before and store the insert in the fridge. In the morning, simply set it in the base and turn it on. This is a game-changer for busy weekdays!
Size Matters
Cut your vegetables into roughly 1/2-inch pieces. Too small and they'll disappear into the stew; too large and they won't cook through properly.
Flavor Boosters
Add a parmesan rind during cooking for incredible depth, or stir in a handful of spinach at the end for extra nutrition and color.
Variations to Try
Mediterranean Style
Swap the herbs for oregano and basil, add kalamata olives and sun-dried tomatoes. Finish with a squeeze of lemon and crumbled feta cheese.
Vegetarian OptionSpicy Southwest
Add 2 chipotle peppers in adobo sauce, swap the herbs for cumin and coriander. Stir in corn and black beans, top with avocado and cilantro.
Spicy Level: MediumAutumn Harvest
Add diced butternut squash or sweet potatoes, swap chicken for turkey. Season with sage and thyme for a cozy fall flavor profile.
Seasonal FavoriteCreamy Comfort
Stir in 1/2 cup of heavy cream or coconut milk during the last 30 minutes. Add mushrooms for extra umami and a luxurious texture.
Rich & CreamyStorage Tips
This stew is a meal prep champion! Here's everything you need to know about storing and reheating:
Refrigerator Storage
Store cooled stew in airtight containers in the refrigerator for up to 5 days. The flavors actually improve after the first day as the ingredients meld together. I like to portion it into individual containers for easy grab-and-go lunches.
Freezer Instructions
This stew freezes beautifully for up to 3 months. Cool completely, then portion into freezer-safe containers, leaving about an inch of space for expansion. Thaw overnight in the refrigerator before reheating. Pro tip: freeze in quart-sized freezer bags laid flat for space-saving storage.
Reheating Methods
Microwave: Reheat individual portions for 2-3 minutes, stirring halfway through. Add a splash of broth if needed.
Stovetop: Warm over medium heat, stirring occasionally. Add broth to thin if necessary.
Slow Cooker: Perfect for reheating large batches. Cook on LOW for 1-2 hours until heated through.
