Try this delicious and healthy Mediterranean-style quinoa casserole!

Quinoa is awesome, right? I am obsessed!  Between my quinoa berry breakfast bowl, my fave Thai quinoa salad, and this quinoa crust pizza, I could probably eat quinoa for every meal all week long and be as happy as can be. Now, we all have that one person in our lives, that makes faces and unimpressed noises whenever we reach for that bag of super seeds. And this is where this quinoa casserole comes in. Because let me tell you, it might just cure that last quinoa skeptic in your life, too!

This Vegetarian Quinoa Casserole with Feta, Mozzarella, Basil and Sun-Dried Tomato Pesto is perfect for summer. I mean, look at it, with its Italian color scheme! So appetizing! It’s light, yet filling at the same time, which I love. Healthy and fresh, with just the right about of saltiness and tang from the feta cheese. Let me tell you, this is a vegetarian recipe for everyone.

The addition of all the Mediterranean flavors (especially the pesto,  feta cheese, and mozzarella) in this quinoa bake makes this casserole truly exciting and special enough to serve to guests.

I could easily have this as a main or side dish. However, it also makes a great side for steak, grilled chicken, fish, shrimp, you name it. Does this work for meal prep? Absolutely! Quinoa tastes delicious hot or just slightly warm, making it perfect for taking to work in a container as a healthy lunch.

Customize it!

As for the ingredients, I went with the classic cheese and pesto combo and only added some fresh onions to up the umami a bit. But this does not mean you cannot play around with it. This is actually a pretty flexible recipe so add whatever fresh herbs, or seasonal grilled vegetables you have on hand! Sliced roasted bell peppers, white beans, sauteed spinach, corn – all of those would taste amazing in here.

How to make Quinoa Casserole:

Prep: Preheat oven to 360F/180C.

Cook the quinoa first. To rinse, pour the quinoa into a fine mesh colander. Rinse under running cold water for about 30 seconds to a minute. Drain it well. This step is important as it removes any bitterness on the outside of the quinoa.

In a medium saucepan, add quinoa and cover with 3 cups of water. Bring to a boil. Once boiling, reduce to a simmer on low heat and cover for 15 minutes or until the water has been absorbed.

Step 1 – Transfer the quinoa in a large baking dish.

Step 2 – Top with sun-dried tomato pesto, Greek yogurt, 3/4 cup mozzarella, 1/2 cup feta, spinach, sun-dried tomatoes, onion, Italian seasoning and vegetable stock (or water).

Step 3 – Mix thoroughly to combine everything together, making sure all the ingredients are all evenly distributed. The mixture should look a bit wet – if it looks a bit too compact to you, add a bit more stock, just a little at a time. At this point, taste and add some salt if needed (keeping in mind that we will add more mozzarella and feta as toppings).

Step 4 & 5 -Sprinkle with remaining 1/2 cup mozzarella, cover tightly with foil. Bake for 30 minutes.

Step 6 -Remove from the oven and sprinkle with 1/4 cup feta, 2 tablespoons of sun-dried tomatoes, and basil. Serve immediately.

What can I use instead of feta?

If you need to swap feta for a different cheese, try goat cheese or halloumi.

Tips & Variations:

  • In the summer, add some roasted or grilled zucchini, bell pepper, or some cherry tomatoes. Don’t go too crazy with tomatoes as they might make the bake soggy. Grilled veggies work best.
  • In the fall and winter, give this a seasonal spin by adding a mix of squash and roasted root vegetables. This is a great recipe for using up leftover veggies.
  • You can make this with freshly cooked quinoa but it also works great with pre-cooked day-old quinoa.
  • Store leftovers in the fridge for up to 4 days.
