Ingredients + Substitutions
- Chicken – To add some animal protein. I opted for skinless chicken breasts, but chicken thighs will also work, see the notes section of the recipe card for details.
- Rice – To add some complex carbohydrates. I used long-grain white rice, but brown rice will also work, see the notes section of the recipe card for details.
- Broccoli – To add some fiber and micronutrients. You can use fresh or frozen broccoli florets. Cauliflower rice is not recommended as the liquid ratios will not work and it will end up mushy.
- Onion + Garlic – To add flavor and fragrance. The recipe calls for a whole onion and garlic cloves, but you can use onion and garlic powder if preferred. See the notes section of the recipe card for details.
- Thyme – While optional, it adds some flavor. The recipe calls for dried thyme, but you can use fresh thyme if preferred, see the notes section of the recipe card for details.
- Milk – To add a bit more protein and ensure the casserole is rich and creamy.
- Broth – To cook the rice and add some flavor. The recipe calls for chicken broth, but vegetable broth, mushroom broth, and water will also work.
- Cheese – To add some healthy fats and a bit more protein. The recipe calls for sharp cheddar cheese, but mozzarella, Gruyere, or Gouda cheese will also work well.
- Salt and Pepper – To season.
Dietary Adaptions
To Make it Gluten-Free: Use certified gluten-free broth.
