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. I like the creamy texture that whole milk brings.
- Cheese: I like a blend of cheddar cheese and goat cheese. Feel free to play with this to match your family's preferences. Parmesan cheese and swiss cheese are also great options.
- 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 florets in this quinoa broccoli cheese bake, make sure you cut them into bite size pieces and steam or blanch them first.
- Breadcrumbs: Use gluten-free breadcrumbs 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 Vegetarian or 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
Can I make this recipe ahead of time?
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.
How do I make gluten free breadcrumbs?
- Start with a loaf of your favorite gluten-free bread. If your bread is fresh, leave it out for a day or two to become slightly stale.
- Preheat your oven to 300°F (150°C).
- Cut the bread into slices, and then into small cubes.
- Spread the bread cubes in a single layer on a baking sheet.
- Bake in the preheated oven for 10-15 minutes, or until the bread cubes are dried out but not browned.
- Allow the bread cubes to cool completely.
- Transfer the cooled bread cubes to a food processor or blender.
- Pulse until the bread is reduced to crumbs. For finer crumbs, pulse for longer. For coarser crumbs, pulse for less time.
- Store your homemade gluten-free breadcrumbs in an airtight container at room temperature for up to a week, or freeze for longer storage.
