Slow Cooker (or oven) Vegetarian Greek Lentil Casserole
Slow Cooker Vegetarian Greek Lentil Casserole is an easy and delicious casserole that can be a side dish or a meatless main dish. I love all the Greek flavors in this low-glycemic and gluten-free casserole with lentils, tomatoes, peppers, and Feta.
On my slow cooker site I’m doing a feature where we spotlight recipes suitable for the new slow cooker that’s shaped like a casserole dish (affiliate link) and it just might be causing me to become obsessed with the new Crock-Pot Casserole Crock Slow Cooker. So when I decided to update this favorite recipe for Slow Cooker Vegetarian Greek Lentil Casserole I couldn’t resist trying it in the Casserole Crock, and it was definitely a winner!
But what if you don’t have the casserole crock and don’t want to buy one? You can definitely make this updated recipe in any large oval 6 Quart slow cooker as well, it just won’t look quite as pretty. Or use the recipe for Original Oven-Baked Vegetarian Greek Lentil Casserole to bake a smaller size in the oven or toaster oven if you prefer. If you like lentils and Greek flavors this is definitely a winner.
How to Make Slow Cooker Vegetarian Greek Lentil Casserole:
(Scroll down for complete printable recipe, including nutritional information.)
- Combine lentils, chopped onion, minced garlic, vegetable broth, bay leaves, black pepper, Greek oregano, and Greek seasoning in the slow cooker and cook on HIGH for 3 – 3 1/2 hours.
- Drain the tomatoes when the lentils are nearly soft.
- Chop up a large red bell pepper and a large green bell pepper and add the peppers and drained tomatoes to the slow cooker, stir, and cook 30 minutes more.
- Then add 1 cup of crumbled Feta cheese, stir gently to combine, and cook 15-20 minutes more.
- We sprinkled over another 1/2 cup of crumbled Feta and baked it 20 minutes in a 400F oven, but the extra cheese and the final cooking in the oven is definitely optional.
- Serve hot, with some thinly sliced green onions for garnish if desired.
Make it a Meal:
Of course you can eat this Slow Cooker Vegetarian Greek Lentil Casserole for a meatless dinner, but I think it would make a fun side dish for Very Greek Grilled Chicken as well, and using the casserole crock will keep your kitchen cool!

- 2 cups brown lentils, picked over and rinsed if needed (see notes)
- 1 onion, chopped small
- 1 T minced garlic (or more)
- 3 cups vegetable stock or broth (see notes)
- 2 bay leaves
- 1 tsp. fresh ground black pepper
- 1 tsp. Greek oregano
- 1 tsp. Greek Seasoning, or more
- 1 14.5 oz. can petite-diced or crushed tomatoes, drained well
- 1 large green bell pepper, seeds removed and finely chopped
- 1 large red bell pepper, seeds removed and finely chopped
- 1 cup + 1/2 cup crumbled Feta cheese (see notes)
- thinly sliced green onions for garnish (optional)
- Spray the slow cooker insert with non-stick spray.
- Combine lentils, chopped onion, minced garlic, vegetable broth, bay leaves, black pepper, Greek oregano, and Greek Seasoning (affiliate link) in the slow cooker and cook on HIGH for 3 – 3 1/2 hours. (Some slow cooker are much hotter than others and older lentils will take a bit longer to cook, but I’d start checking to see when the lentils are getting done after about 2 hours. I heard from a reader who made this in a round slow cooker who said her lentils were done much sooner than 3 hours, so I would especially check sooner if you’re using a different type of slow cooker.)
- When the lentils are nearly soft, drain the tomatoes well in a colander placed in the sink.
- Cut seeds out of the bell peppers and finely chop.
- When the lentils are soft enough that you think they are almost done, stir in the drained tomatoes and finely chopped bell peppers and cook 30 minutes more.
- Then add the 1 cup of crumbled Feta, stir gently, and cook 15-20 minutes more.
- If you want to add more crumbled Feta and brown it in the oven, preheat the oven to 400F/200C.
- Remove the crock from the slow cooker, sprinkle the top with the extra 1/2 cup of crumbled Feta, and bake 20 minutes. (This step is recommended, but it’s completely optional if you don’t have a casserole crock or don’t want that much Feta.)
- Serve hot, garnished with thinly sliced green onions if desired.
I made this in the Crock-Pot Casserole Crock Slow Cooker (affiliate link) but you can use any large oval slow cooker as well.
Lentils that come in a package often don’t need to be rinsed, but if they seem even slightly dusty or gritty, rinse the lentils in a strainer. Canned vegetable broth is fine here. Use 2 cans and just freeze the extra for another recipe. Use more or less Feta Cheese to taste.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Dried beans and lentils are a great low-glycemic food for any phase of the South Beach Diet, but they’re a limited food for Phase One. However, in a dish like this Slow Cooker Vegetarian Greek Lentil Casserole with lots of other vegetables and some cheese you can have a normal-sized serving. Lentils are too high in carbs for low-carb diet plans, but you can make this lower in carbs by using more peppers and cheese and less lentils.
