Ingredients
- 2 cups cooked chicken, shredded or diced
- 3 cups fresh broccoli florets
- 1 cup cooked brown rice or quinoa
- 1 cup heavy cream
- 1 cup shredded mozzarella cheese
- ½ cup grated parmesan cheese
- 4 cloves garlic, minced
- 1 tablespoon olive oil
- 1 teaspoon dried Italian herbs
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ½ teaspoon crushed red pepper flakes (optional)
- Cooking spray or additional olive oil for greasing
Instructions
Preheat the Oven: Start by preheating your oven to 350°F (175°C). This ensures that the casserole will cook evenly.
Prepare the Baking Dish: Lightly grease a 9×13 inch baking dish with cooking spray or a drizzle of olive oil to prevent sticking.
Cook the Broccoli: In a medium pot, bring water to a boil. Add the broccoli florets and cook for about 3-4 minutes until bright green and tender-crisp. Drain and set aside.
Sauté the Garlic: In a skillet, heat the tablespoon of olive oil over medium heat. Add minced garlic and sauté for about 1 minute until fragrant — be careful not to burn it.
Combine the Cream Sauce: In a separate bowl, mix together the heavy cream, Italian herbs, salt, black pepper, and red pepper flakes (if using). Stir in half of the grated parmesan cheese and set aside.
Combine All Ingredients: In a large mixing bowl, combine the cooked chicken, cooked broccoli, cooked rice or quinoa, sautéed garlic, and the cream sauce. Stir until everything is well coated.
Transfer to Baking Dish: Pour the mixture into the prepared baking dish, spreading it evenly. Top with shredded mozzarella cheese and the remaining parmesan cheese.
Bake the Casserole: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the cheese is melted and bubbly, and the edges are slightly golden.
Serve and Enjoy: Remove the casserole from the oven and let it cool for a few minutes before serving. Garnish with fresh herbs if you desire, and enjoy your delicious Garlic Parmesan Chicken Broccoli Casserole!
Pro Tips for Perfect Results
Use Leftover Chicken: For a quicker prep, use leftover rotisserie chicken or any pre-cooked chicken to speed up the process.
Broccoli Freshness: Ensure your broccoli is fresh for the best flavor and texture. Avoid using frozen broccoli as it may become mushy.
Cheese Choices: Feel free to experiment with different kinds of cheese. Cheddar, Gruyere, or even a blend can add a unique twist to the dish.
Make it Ahead: This casserole can be prepared a day in advance. Just assemble everything in the baking dish, cover it with foil, and refrigerate until you’re ready to bake.
Check for Doneness: If the top isn’t browned to your liking, you can broil it for an additional 2-3 minutes at the end. Keep a close eye to avoid burning.
Variations and Substitutions
- For a Healthier Option: You can substitute heavy cream with Greek yogurt or low-fat sour cream to reduce the calorie content.
- Vegetarian Version: Swap the chicken for chickpeas or grilled mushrooms to create a vegetarian casserole that still packs a protein punch.
- Nut-Free: Ensure the cream base and any additional sauces used are nut-free if allergies are a concern.
- Grain Swap: Instead of rice or quinoa, consider using cauliflower rice for a low-carb option or couscous for a different taste.
Storage and Reheating Tips
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3-4 days. The garlic parmesan flavors will continue to meld and become more delicious over time!
- Freezing: You can freeze the casserole before or after baking. If freezing unbaked, cover tightly with foil and plastic wrap and use within 2-3 months. If already baked, cool completely and freeze, then reheat from frozen by adding an additional 10-15 minutes to the baking time.
- Reheating: To reheat, simply place the casserole in a preheated oven at 350°F (175°C) for about 20-25 minutes or until heated through.
