FAQs

Can I make this casserole ahead of time?

Yes, assemble it ahead and refrigerate for up to 24 hours before baking.

What type of quinoa works best?

White quinoa has a milder taste and works well, but red or tri-color quinoa also adds texture and color.

Do I need to pre-cook the broccoli?

Lightly steaming or sautéing helps ensure it’s tender, especially if you’re using fresh broccoli.

Can I use canned chicken?

Yes, though fresh or rotisserie chicken gives better texture and flavor.

Is it okay to skip the cheese?

You can, but the cheese adds to the creaminess and flavor—use a dairy-free option if needed.

Can I add other vegetables?

Absolutely. Peas, carrots, spinach, or bell peppers are all great additions.

How can I make this vegetarian?

Omit the chicken and add chickpeas, white beans, or extra veggies for a protein boost.

Can I use a different type of cheese?

Yes! Monterey Jack, mozzarella, or even a sharp white cheddar all work well.

Will the quinoa get mushy?

Not if it’s cooked just until tender before being added. Avoid overcooking the quinoa.

Can I use a different grain instead of quinoa?

Yes, brown rice, couscous, or even orzo can work, but adjust cooking times as needed.
