Ingredients
- For the base:
- 3 cups cooked chicken, shredded or chopped (rotisserie works great)
- 4 cups broccoli florets, fresh or thawed from frozen (bite-sized)
- For the sauce:
- 1 cup plain Greek yogurt (nonfat or low-fat)
- 1/2 cup low-sodium chicken broth
- 1 cup shredded low-fat cheddar cheese
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 tablespoon Dijon mustard
- 1 tablespoon olive oil
- 1 teaspoon lemon juice (optional, brightens flavor)
- 1/2 teaspoon salt and 1/4 teaspoon black pepper (adjust to taste)
- For the topping:
- 3/4 cup whole-wheat breadcrumbs or panko
- 2 tablespoons grated Parmesan cheese
- 1 tablespoon olive oil or melted butter (unsalted)
- Notes:
- Use unsalted butter or olive oil to control sodium.
- If using frozen broccoli, thaw and squeeze out excess water first.
How to Make Healthier Broccoli Chicken Casserole:
- Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
- Mini-tip: Preheating ensures even browning of the topping.
- Steam or blanch the broccoli for 3–4 minutes until bright green and just tender. Drain and cool slightly.
- Why this step matters: Slightly undercooked broccoli holds texture in the bake.
- In a skillet, heat 1 tablespoon olive oil over medium heat. Add the chopped onion and cook 4–5 minutes until soft and fragrant. Add garlic and cook 30 seconds.
- Mini-tip: Cooking the onion first deepens the savory flavor of the sauce.
- Stir in the Greek yogurt, chicken broth, Dijon mustard, lemon juice, salt, and pepper. Heat gently until warm and smooth — do not boil. Remove from heat and stir in 3/4 cup shredded cheddar.
- Why this step matters: Warming melts the cheese into the yogurt for a creamy sauce without curdling.
- In a large bowl, combine the shredded chicken, steamed broccoli, and the warm sauce. Mix until everything is evenly coated. Taste and adjust seasoning.
- Pour the mixture into the prepared baking dish and spread it evenly. Sprinkle the remaining 1/4 cup cheddar over the top.
- In a small bowl, mix breadcrumbs, Parmesan, and 1 tablespoon olive oil or melted butter. Sprinkle this mixture evenly over the casserole.
- Mini-tip: For extra crunch, toast breadcrumbs in a pan for 2 minutes before topping.
- Bake uncovered for 20–25 minutes until the top is golden and the edges bubble. Let rest 5–10 minutes before serving.
- Why this step matters: Resting helps the casserole set so it slices neatly.
How to Serve Healthier Broccoli Chicken Casserole
- Serve warm straight from the oven with a fork-tender scoop and a sprinkle of fresh parsley.
- Pair it with a crisp green salad or steamed carrots for color and crunch.
- For a heartier meal, serve alongside creamy pasta like our creamy chicken broccoli fettuccine alfredo for a full comfort-food spread.
How to Store Healthier Broccoli Chicken Casserole
- Fridge: Cool to room temperature, cover tightly with foil or transfer to an airtight container. Keep 3–4 days.
- Freezer: Freeze in a freezer-safe container for up to 3 months. Thaw overnight in the fridge before reheating.
- Reheat: Warm individual servings in the microwave for 1–2 minutes, stirring halfway. Reheat a larger portion covered in a 350°F (175°C) oven for 15–20 minutes until heated through.
Tips to Make Healthier Broccoli Chicken Casserole
- Use rotisserie chicken to save time and add flavor.
- Don’t overcook broccoli before baking — it should stay slightly firm.
- Swap Greek yogurt for light sour cream if you prefer a milder tang.
- Toast breadcrumbs for extra crunch and nuttier flavor.
- Taste the sauce before baking to adjust salt and lemon.
Variation
- Vegetarian: Replace chicken with cooked chickpeas or cubed tofu and use vegetable broth.
- Gluten-free: Use gluten-free breadcrumbs or crushed gluten-free crackers and ensure broth is gluten-free.
Can I use frozen broccoli instead of fresh?
Yes. Thaw the broccoli and drain well, then pat dry to remove excess water. This prevents a soggy casserole.
Can I make this ahead of time?
You can assemble the casserole up to a day ahead, cover, and keep it in the fridge. Add the breadcrumb topping just before baking for best texture.
How do I keep the topping crispy after reheating?
Reheat uncovered in a 350°F (175°C) oven for 10–15 minutes. A quick 2–3 minute broil at the end will re-crisp the top if needed.
