Italian Quinoa Casserole is a comforting vegetarian casserole that’s full of protein and vegetables!
Crispy, cheesy quinoa might be my best friend.
This quinoa casserole is based on my wildly popular Crispy Quinoa Bake. It’s just as crispy and even more comforting with its warm Italian flavors. There are tons of hearty vegetables like zucchini, eggplant, and red bell pepper, not to mention my favorite vegetable – CHEESE.
I originally shared this recipe about four years ago, but wanted to update it with fresh photos and video for you! The video will show you just how easy this is to throw together, especially if you have leftover quinoa sitting around.
If quinoa is a new-to-you food, I wrote a whole post on how to cook quinoa!
This Italian Quinoa Casserole can be easily customized! Here are a few ideas to get you started:
- You can alter the amount of quinoa to be more or less depending on what you have on hand
- Use whatever veggies you have on hand such as cooked broccoli or frozen spinach
- Swap spices and veggies to create totally different flavors, like in my Crispy Quinoa Bake
- Leave out the cheese to make it vegan
- Assemble the whole thing ahead of time and refrigerate or freeze, adding a few extra minutes of cook time if cooking it cold
- Spread thin on a rimmed baking sheet instead of using a 9×13 pan for extra crispy quinoa

Italian Quinoa Casserole
Ingredients
- 1 cup uncooked quinoa
- Olive oil
- 2 cups vegetable stock
- 1 eggplant,, peeled and cut into 1 inch cubes
- Coarse kosher salt and freshly ground black pepper
- 1 medium onion,, diced
- 1 red bell pepper,, diced
- 1 zucchini,, cubed
- 2 cloves garlic
- 28 ounces canned diced tomatoes, drained
- 15 ounces canned great northern beans, rinsed and drained
- 1/4 cup parsley,, finely chopped
- 1/2 teaspoon dried thyme
- 1/2 teaspoon dried rosemary
- 3/4 teaspoon dried oregano
- 1/8 teaspoon crushed red pepper
- 2 cups Italian cheese blend
- 1/2 cup freshly grated Parmesan cheese
Instructions
- Preheat the oven to broil on high and place an oven rack in the highest position. Spray a 9×13 baking dish with cooking spray. Set aside.
- Arrange eggplant in a single layer on a large baking sheet. Toss with a drizzle of olive oil and sprinkle with salt and pepper. Broil in the oven until soft and beginning to brown, stirring once or twice, about 5-10 minutes. Keep a close eye on them as oven temperatures may vary, you don’t want them to burn. After removing the eggplant, lower the rack to the middle position and turn the oven to bake at 375ºF.
- Place the quinoa in a fine mesh strainer and rinse throughly with cool water for at least two minutes. Drain. In a medium saucepan, heat 2 teaspoons olive oil over medium-high heat. Add the quinoa and cook, stirring, for about one minute. The quinoa should begin to dry out and pop a bit. Add the vegetable stock. Stir and bring to a boil. Turn the heat down to low and cook, covered, for 15 minutes. Remove the pan from the heat and let stand, covered, for 5 minutes.
- Meanwhile, in a large skillet, heat 1 tablespoon olive oil over medium heat. Add onions and peppers and cook, stirring occasionally until soft, about 7 minutes. Add garlic and zucchini and cook 3 more minutes.
- Fluff the quinoa with a fork and place it in a large bowl. Add onion mixture, eggplant, tomatoes, beans, parsley, thyme, rosemary, oregano, crushed red pepper, 1 cup of Italian cheese blend, and salt to taste. Mix thoroughly and transfer to prepared baking dish. Bake 30 minutes, top with remaining cheese, and bake 10 minutes more or until melted and just beginning to brown.

Made this and substituted spinach and mushrooms for eggplant that I didn’t have, and also black beans was all I had.
Came out absolutely delish! Great recipe 🙂

Great recipe! love it thanks for sharing. I love Italian food I always wanted to make some but due to lack of time I couldn’t therefore I have to go to the Italian restaurants. I remember one restaurant in Oakland called “Belotti” pretty great restaurant love their food.
Lindsay Moe says
I also have a love for Italian restaurants! I’m so glad you enjoyed this recipe!

Found your recipe on Pinterest. I made it last night with leftover roasted veggies I had already (zucchini, cauliflower, broccoli, & carrots). And I don’t like chunks of tomatoes, so I used marinara sauce instead. It was DELICIOUS! And I’m now eating the leftovers that I heated in a skillet liked you recommended on the Mexican version. Also delicious! Thanks for the inspiration.
Lindsay Moe says
I’m so glad you enjoyed it! Thanks for sharing your swaps. The skillet leftovers are the BEST PART!!

I found your site by googling the ingredients I needed to use up in my frig and would not have thought of doing it quite this way but I was very happy with the result. I omitted the beans and upped the zucchini to 4 small ones…all veg roasted first. The flavor and texture of the roasted veggies provides a satisfying texture which can be hard to find in vegetarian dishes (especially when trying to please our family carnivores!). Thanks!

I’m so glad you enjoyed it and were able to use up the ingredients in your fridge!

I made the Italian quinoa casserole last night, yummy! I didn’t have eggplant so doubled the zucchini and just sprinkled some Parmesan on top since I try to avoid dairy but my husband likes it. It makes a lot so I put some in the freezer for another day. I might add some marinara sauce to the leftovers to hold it together since the cheese was omitted without compromising the yummy spice blend.

I’m looking forward to trying this recipe! I was wondering what would be a good substitute for the tomatoes as I can not eat them? I’m assuming they are there to provide extra moisture?
Thanks!
Lindsay Moe says
You would actually want to remove as much moisture as possible from the tomatoes before cooking, so I think it would be fine to leave them out entirely or replace them with a soft or cooked vegetable of your choice. Enjoy!
Shari says
This sounds delish! Can this recipe be put together the day before, refrigerated and then baked the next day to serve? This is what I always do with my baked ziti (and it allows the flavors to all blend together in a very delicious way) but didn’t know if it would work just as well with quinoa.
Lindsay Moe says
Absolutely! I have also frozen it to cook later and it comes out great.
