Ingredients for Making Quinoa and Broccoli Casserole
Butter: I use unsalted butter, so I have better control over the salt.
Flour: I used gluten-free flour; you can use all-purpose flour if you are not gluten-free.
Milk: Use whatever milk you prefer.
Cheese: I like a blend of cheddar cheese and goat cheese. Feel free to play with this to match your family's preferences.
Seasonings: Garlic powder, cayenne pepper, salt, and pepper add just the right complexity of flavors to the dish. If you have little ones or are particularly sensitive to heat, you and omit the cayenne pepper.
Chicken: I use cooked chicken breasts, but chicken thighs would work as well.
Quinoa: The texture of white quinoa is better than that of red quinoa in casserole dishes.
Broccoli: To use fresh broccoli in this quinoa broccoli cheese bake, make sure you steam or blanch it first.
Breadcrumbs: Use gluten-free bread crumbs if necessary.
Tips, Tricks, and Variations
- Add 10 ounces of frozen artichokes, thawed and chopped.
- Saute 1 cup diced onion and 8 ounces sliced mushrooms and add them to the chicken and broccoli mixture
- When you are cooking quinoa for casseroles and want the best texture, you can let it cool on a baking sheet. This helps to prevent it from getting gummy.
- If quinoa isn't your thing, feel free to substitute cooked brown or white rice. Millet, farro, or any other grain of you liking would also work.
- Want to make this a side dish? Just omit the chicken, and you have a delicious quinoa broccoli casserole.
Make it Vegan
To make this recipe vegan, use unsweetened almond milk, vegan butter, and vegan cheese. Substitute cooked and crumbled tempeh for the chicken.

Frequently Asked Questions
Yes, you can make this recipe up to a day ahead and cook it just before you plan on serving.
Let the casserole dish come to room temperature or put it in a cold oven and let the dish heat up with the oven. This will prevent the cold dish from cracking due to heating up too quickly.
Feel free to use whatever kind of bread crumbs you have on hand. Panko, regular, or gluten free all work. (I especially like the crunch from panko breadcrumbs.)
