Broccoli Quinoa Casserole Recipe
It’s a better broccoli casserole with the substitution of quinoa for rice. This dish has a slightly nutty flavor from the quinoa, a creamy, smooth texture from the cheese, and a fresh crunch from the broccoli. In addition, all the nutrition that quinoa packs make this a winning combo.

What is Quinoa?
Quinoa is a seed, not a grain. However, quinoa is a complete protein, providing all nine essential amino acids, which are rare in a plant product. One cup of cooked quinoa contains 222 calories and 4 grams of fat, 39 grams of carbohydrates, 5 grams of fiber, and 8 grams of protein. It has 15 percent of the daily value for iron and is also a good source of calcium, magnesium, and vitamin E.
Quinoa is also a gluten-free and cholesterol-free whole food. As well as it’s naturally kosher.

What does quinoa taste like?
It has a nutty flavor but a fluffy texture. It easily takes on whatever sauce or flavor you add to it.

It does not tell what temp to bake this. I doubled the broccoli, it was way too much cheese and too little broccoli. It also says to drain the quinoa after cooking with the broccoli, there was nothing to drain, it was not enough liquid, quinoa started to burn. Maybe I did something wrong
