This recipe is inspired by broccoli rice casserole, but it's not your typical super creamy casserole.

However adding flax eggs to the mix helps achieve more of a creamy consistency. (See notes below.)

Author: Kaitlin - The Garden Grazer

Course: Main Dish

Cuisine: Gluten-Free, Vegan

Servings: 8 medium bowls

Ingredients

1 1/2 cups white quinoa (uncooked)
1/2 yellow onion
2-3 cloves garlic
1 large head broccoli (or 3-4 cups broccoli florets)
8 oz. mushrooms (I use cremini)
1 1/2 cups vegan cheddar shreds (plus more for topping if desired)
1 tsp. smoked paprika
Salt/pepper to taste
1-2 flax eggs* (optional)

Instructions

Rinse quinoa well. Simmer covered in 3 cups water (or veggie broth for more flavor) for 15-20 minutes or until liquid is absorbed.
Meanwhile, dice onion and mushrooms. Mince garlic. Chop broccoli florets.
Preheat oven to 375°F (190°C).
Sauté onion and mushrooms over medium-high heat for about 5-7 minutes or until slightly softened. Remove any extra liquid from the mushrooms.
Steam broccoli for 2-3 minutes. (Or simply sauté in the skillet you cooked the onion and mushrooms in.)
In a large bowl, combine all ingredients with the cooked quinoa (and flax egg if using). Mix well.
Add mixture to a 9x13" baking dish (lightly sprayed if desired). Spread out evenly and lightly press down. Sprinkle additional cheese on top if desired.
Bake for about 15-20 minutes.

Notes

*To make a flax egg: mix 1 Tbsp. flax with 3 Tbsp. water. Let sit for a few minutes to thicken.

Freezing instructions: You can freeze this before or after baking. If freezing after baking, let it cool completely before freezing. Then place in a freezer & oven safe container. Cover tightly with plastic wrap, then foil. Before serving, it's best to thaw casserole in the refrigerator overnight if possible. If not, be sure to leave extra time for baking.

To reheat after freezing: heat in a 375 degree oven for 20 minutes or until center is hot. Add additional time if casserole isn't thawed completely before baking, checking every 10-15 minutes. If the top is browning too quickly, cover with foil and continue baking until heated through. Tip: you can also freeze smaller portions in individual containers to reheat a single serving or a couple servings at a time.

Made this a regular dinner addition. Delicious! I use one regular egg instead of the flax egg. I actually like this better than the rice version.

I was looking for a quinoa recipe using stuff I had. I didn't have mushrooms so left them out. I used Gouda in it and Parmesan on top cause it's what I had. I added red pepper flakes for spice. It was great. I think it can work with most cheeses.

I made this recipe this weekend & loved it! I didnt pay attention, & boiled the quinoa in more than 3 cups of water. I drained the excess, but my quinoa was still fairly saturated with water. The result was incredibly creamy, more like the traditional rice casserole, but so much healthier. Thank you for this recipe!

Hi, I only have red quinoa on hand. Would you happen to know if I could use the red instead of the white? And if so, what adjustments should I make? Thank you!

  Red quinoa has a "nuttier" flavor but should work as well. No need to make any adjustments! Hope you enjoy.

Can I use millet instead of quinoa? I just have too much millet.

  I've never tried that but it's certainly worth a try! Millet and quinoa can often be used interchangeably I think. Let me know if you end up trying it - would love to hear how it turns out!

Any suggestions for an alternative to mushrooms? I hate mushrooms, but love every other ingredient in this recipe!

- Kaitlin | The Garden Grazer

  You could just omit the mushrooms without a replacement. They aren't a necessary component to this dish, though I do enjoy the texture and added nutrition.
