High-Protein Chicken and Rice Casserole (Freezer-Friendly)

This is the kind of dinner that solves two problems at once: something everyone at the table will actually eat, and something you can double and freeze for a night when cooking isn’t happening. Greek yogurt stands in for the usual cream-of-something soup, which quietly pushes the protein up without changing how it tastes.

Why this casserole works

The recipe card below keeps the exact ingredient list and baking method in one place. The useful trick is the Greek yogurt: it gives the casserole a creamy texture without making it taste tangy or heavy.

Cooked chicken and cooked rice make this a practical weeknight bake instead of a long project. Rotisserie chicken is the easiest shortcut, and frozen vegetables can go straight in.

Ingredients Method Notes

Ingredients

  

• 3 cups cooked, shredded chicken breast about 1.5 lbs / 680g — rotisserie chicken works great here
• 2 cups cooked brown rice
• 1 cup plain Greek yogurt
• 1 cup shredded cheddar cheese divided
• 1 cup frozen mixed vegetables peas and carrots work well
• 1/2 cup chicken broth
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• salt and pepper to taste
• 1/2 cup panko breadcrumbs optional, for topping

Method

 

1. Preheat the oven to 375°F. Lightly grease a 9×13-inch baking dish.
2. In a large bowl, combine the shredded chicken, cooked rice, Greek yogurt, half the cheddar cheese, frozen vegetables, chicken broth, garlic powder, onion powder, salt, and pepper. Mix until evenly combined.
3. Spread the mixture into the prepared dish. Top with the remaining cheddar cheese and panko, if using.
4. Bake for 25-30 minutes, until bubbly and golden on top.
5. Let rest 5 minutes before serving.

Notes

Freezer-friendly: assemble unbaked, cover tightly, and freeze for up to 3 months. Bake from frozen at 375°F with about 20 extra minutes, or thaw overnight first for a normal bake time.

Make-ahead and swap tips

For freezer planning, assemble the casserole unbaked in a freezer-safe dish, cover it tightly, and freeze for up to 3 months. Bake from frozen with extra time, or thaw overnight for a normal bake. For more make-ahead planning, see Cook Once, Eat Twice.

White rice or cauliflower rice both work as swaps for brown rice. Prefer bowls over a baked casserole? Try the Chicken and Rice Meal Prep Bowls instead. Similar meal-prep idea, different protein: Ground Turkey Meal Prep.

How much protein is actually in this

About 43 grams of protein per serving — roughly 35g from the chicken, plus contributions from the Greek yogurt and cheddar cheese. The Greek yogurt swap for cream soup is most of what makes this higher-protein than a typical casserole.

Frequently Asked Questions

Can I make this ahead for the week?
Yes — it reheats well and portions easily into glass meal-prep containers for lunches or quick dinners.

Can I freeze it after baking instead of before?
Yes, either works. Baked leftovers freeze fine too — the texture softens slightly on reheating, but it’s still good.

Is this kid-friendly?
Yes — mild flavor, cheesy, familiar comfort-food format. One of the easier ways to get a genuinely high-protein dinner past picky eaters.
