This comforting lentil casserole is a family favourite! Lentils and kidney beans are simmered with diced tomatoes, rosemary, and garlic then topped with shredded cheddar cheese and then put in the oven for a quick broil for this easy weeknight meal you will want to eat on repeat.

Easy Vegetarian Lentil and Bean Casserole (1)

Keeping with the comfort theme this week, I want to share with you one of my most favourite easy vegetarian meals. I've been making this one for YEARS and it's one I come back to time and time again because it is SO simple, totally comforting and absolutely delicious.

One of my favourite things about this recipe (besides the ooey gooey melted cheese) is that is it made from pantry ingredients. This lentil casserole has been a dinner saviour many nights when I hadn't planned a thing and had no idea what to do.

Calling it a casserole might be a bit of a stretch because 95% of the cooking is done stovetop, but 'bean stuff' which is the term I've come to call it by around the house just didn't sound as appealing.

It's kind of like chilli but seasoned with rosemary and garlic in a pot with cheese melted onto it. If cheddar isn't your thing, mozzarella, Monterey Jack or pretty much any other melting cheese would be good here, including your favourite melting vegan cheese.

How to make this quick lentil casserole:

Heat a large pot to medium heat and add the olive oil. When the olive oil is heated add the celery and onion and cook them until they begin to soften then add the diced tomatoes, kidney beans, lentils, garlic and rosemary. Season with salt and pepper, then bring the pot to a boil.

Once the pot is boiling, reduce the heat to a low simmer and allow it to cook for 20 minutes.

When the mixture is cooked, transfer it to an oven-safe dish then top with the grated cheese and broil on high for 2-4 minutes or until the cheese melts.

What to serve with this lentil casserole

When I serve this at home we just grab a plate and dig in but it would be equally as awesome with a side salad or some other form of green veggies.

    This lentil "bean stuff" looks great. I've gotten a better appreciation for lentils over the years, and anything with cheese on top is a winner in my book.

    This looks amazing! Something my whole family can enjoy, and omitting the cheese it's vegan and plant-based!

      Thanks so much! And yes, it would also be great without the cheese - you just don't need to bake it then.

    Made this tonight and the whole family loved it! Made one tweak because I didn't have rosemary and added taco seasoning instead - soooooo delicious!

    Oh my goodness... this was absolutely amazing. I was totally convinced, while making it, that it wouldn't be that great.. I was very wrong. Simple to make, packs a ton of flavor, and very filling. Thank you for sharing!!

    This looks delicious. Do you think I could make it in a crock pot? (except for the cheese).

      Hi Alyssa! I have never cooked it in a crock pot, but I don't see any reason not to try it in there! I'd love to hear how it turned out if you do 🙂

    • Abbie says

      Hi, this looks really nice! Do you think it will freeze well? I was thinking to prep everything and freeze before broiling, then bake it with cheese when I'm ready? Thanks!

      • Courtney says

        Thank you! I have never tried doing that before, but I think that if you prepare it to the point where you add cheese you could easily freeze it. If you do it, I would love to hear how it turns out!

  14. Carrie says

    Does it have to be canned lentils? Wouldn’t raw lentils cook while it simmers?

    Reply

    • Courtney says

      I have never tried it with dried lentils, so I am unsure if there will be enough liquid in the tomatoes to cook them.

      Reply

      • EM Scott says

        what do you bring to a boil as there's no liquid in the list of ingredient's nor the instructions?

      • Courtney says

        There is liquid in the canned tomatoes. You bring the contents of the pot (which is everything but the cheese) to a boil.

  15. Mav says

    Will be making this....will be good ( I’m sure ) topped with mashed potato and cheese. Vegetarian Shepherds pie is always a favourite!

      Green or French lentils would work well.

    My family love this lentil bake, ice cooked it twice during ‘lockdown’ and it’s packed with protein and vegetables and you can add other vegetables if you wish. My kids are 20 and 15 and don’t agree on most foods but love this. Best of all it’s quick and so easy to prepare, no fancy ingredients! Thank you

    Excellent! Juicy, easy to put together, and it was a satisfying option for ‘meatless Monday’ 🙂
    It looks like a chili but is a nice change! I didn’t have Rosemary where I was cooking so I used Italian seasoning and it was very good. I toasted some cheese bread for dipping.

    This was so delicious, maybe better the next day too. I added a heaped teaspoon of vegetable stock powder for extra seasoning. I served it over a bed of baby spinach with a dollop of sour cream and some pickled jalapeños. This is an easy and quick meal.

    Why can't you start out in a big skillet?

      There's no reason why you couldn't. I've been making this since before I had a skillet that could transfer to the oven, so I make it this way out of habit.

    This is a weeknight favorite. I substitute celery for carrots. When I have kale, I'll also add that. But it is SO good! It tastes like pizza with the broiled cheese. This meatless meal won't have you missing meat at all! Thanks for sharing.

    Where do you get 19 ounce cans of lentils and kidney beans? Did a search and only found 19 ounce cans of lentil soup, the rest are mostly 15 oz. Can you give apex weight/grams of the beans?

    Reply

    • Courtney says

      Hi Bill!

      I buy them at any grocery store I have ever shopped at. If for some reason 19 oz cans are not available in your area, the volume of the can drained is about 2 cups. I hope that helps!

      • Bill says

        Thanks. I only buy organic, maybe that's why.

      • Laurie S Darling says

        so if substituing dry lentils, would the measurement be two cups cooked? TIA

    Yummers. Made it for my work week lunch prep. Very tasty. I added a bit more garlic, cause well garlic!

    If I don't have canned beans what's the ratio with dry beans in the bag? Learning how to cook dry beans and I'm still not great at this. Thinking rice was difficult is now a thing of the PAST.

    If I were to use dry lentils vs. canned, what quantity would I cook? A cup? Thank you! So excited to try this.

    This was delicious and very easy to make!
    I made one change. I used fire roasted tomatoes, only because I didn't have plain diced tomatoes. I would do that again. I might add corn to it next time.
    Thanks for sharing your recipe.

    Do I add the liquid in the diced tomatoes ?

    I’m slowly getting my carnivore husband to enjoy plant based meals with me. I doubled the celery, added a chopped bell pepper and used my mini rice cooker to cook a cup of dry lentils (I won’t pay $3.29 for a can of lentils that are tasteless and mushy). This was FANTASTIC! Thanks for sharing!!

    Do you soak the lentils if using from dry and not canned?
