Quinoa Casserole
I thought it was time to publish a recipe with quinoa on my blog. Until today, I’ve created some tasty vegan recipes with rice, potatoes, and pasta. However, in my opinion, quinoa deserves to be used more often. This pseudo-grain is very healthy, delicious and protein-rich, furthermore, it’s not a real grain.
Quinoa is also gluten-free and can, therefore, be eaten by people suffering from celiac disease. I also love the fact that quinoa contains plenty of healthy, plant-based protein. Read more about the health benefits of quinoa in this amazing article.
Since I adore casseroles, I decided to make a broccoli quinoa casserole with vegan cheese. This savory broccoli soufflĂ© can be prepared in less than 45 minutes and it tastes amazing. Especially in the evening, when you want to enjoy a hearty comfort meal, there is nothing better than a cheesy broccoli casserole. Don’t you think so?
Quinoa Or Rice?
Of course, you can also prepare this easy broccoli casserole with rice instead of quinoa. So if you don’t have quinoa in your pantry or doesn’t like the taste of it, no problem! You can just cook rice and use it instead of quinoa in the recipe.
I am sure a broccoli rice casserole will taste delicious as well! Another alternative would be to use potatoes to enjoy a delicious broccoli potato gratin!
Ingredients Of This Healthy Broccoli Casserole
Instead of cheddar, I used my easy vegan cheese sauce because it only takes 3 minutes to prepare it. Of course, you can also use store-bought cheese from the supermarket. You can make this quinoa broccoli casserole with any kind of plant-based milk.
For example, you could use almond milk, oat milk, cashew milk, coconut milk, etc., depending on your taste. The higher the fat content of the milk, the better the casserole will taste!
In addition, I also added chickpeas, because they are another great source of plant-based protein and taste very delicious!
I topped the broccoli quinoa bake with homemade “breadcrumbs“. The ingredients are oats, nutritional yeast flakes, and a few spices. In my opinion, breadcrumbs make a gratin even more delicious.
How To Make A Broccoli Quinoa Casserole?
It really isn’t complicated to make this cheesy broccoli casserole. First, prepare the quinoa by rinsing it under running water for about a minute. Then cook the quinoa in salted water or vegetable broth for about 15 to 20 minutes. Meanwhile, you can already roast the broccoli in the oven.
Once both quinoa and broccoli are done, mix the quinoa with plant-based milk, chickpeas, vegan cheese, and spices. Pour the quinoa mixture into a greased casserole dish, add the roasted broccoli. Finally, put vegan cheese and breadcrumbs on top of the broccoli, and bake the gratin in the oven for about 20 minutes.
How To Store Leftovers?
This broccoli bake tastes best when it’s still warm. You can put leftovers in the refrigerator and enjoy them either cold the next day, or reheat in the microwave or in the oven.
It is also possible to freeze leftovers in zip-lock bags. Simply defrost at room temperature or in the fridge and reheat either in the oven or in the microwave.

Hi! is the quinoa listed in the recipe calculated as cooked or uncooked weight? Thank you!
Hi, that’s the uncooked weight. 🙂
Just made this today turned out very good. I added some roasted kale I roasted the broccoli and kale in my air fryer eliminating the oil. Will definitely be making again.
Sounds great! Happy you liked it, Judy. 🙂
Yum!!! We loved this! I didn’t have any quinoa, so I used a mixture of quick cook brown rice and white rice. That worked fine Also used some pepper jack vegan cheese in place of the cheese sauce. I made a double batch, and put it in a huge lasagna pan. This one is a keeper!
