Ingredients to make Chicken and Rice Casserole

Here are the ingredients to gather to make this recipe today:

  • boneless skinless chicken breast – you could also use boneless, skinless chicken thighs
  • uncooked rice – we recommend basmati, jasmine, or long-grain white rice
  • frozen California vegetable blend – we call for a bag of “California” blend frozen veggies, which is common at all grocery stores and includes a mix of frozen broccoli, cauliflower, and carrots
  • onion – use a small yellow or white onion
  • butter
  • all-purpose flour – may use regular unbleached all-purpose flour or gluten-free flour. For gluten-free flour, we always reach for Bob’s Red Mill Gluten Free 1-to-1 Baking Flour. If you don’t need casserole that is gluten free, you can use an equal amount of unbleached all-purpose flour. We’ve tested this recipe with both, and both flours achieve great results
  • broth – use chicken or vegetable broth
  • milk – you can use any dairy or non-dairy milk of choice; we used 2% cow’s milk
  • pantry spices – you’ll need garlic powder, paprika, fine salt, and black pepper
  • Dijon mustard
  • Shredded cheddar cheese

Frequently Asked Questions
