Essential Ingredients for Your Cheesy Casserole

Creating this magnificent broccoli and cauliflower casserole requires a handful of simple, readily available ingredients. Each component plays a crucial role in building the dish’s incredible flavor and texture:

Ingredients List:

• Large Head Cauliflower: The foundation of our casserole. Choose a firm, white head, and cut it into small, uniform florets for even cooking.
• Large Head Broccoli: Adds vibrant color and a slightly different texture and flavor profile. Like the cauliflower, cut it into small, consistent florets. If you have extra, consider making an Easy Broccoli Salad!
• Cooked Chicken Breast: Provides a lean protein boost, making this a complete meal. Diced chicken breast works perfectly, or use any boneless, skinless chicken part you prefer. This recipe is also excellent for utilizing leftover roasted or grilled chicken.
• Cream Cheese: Softened to room temperature, cream cheese is key to achieving that incredibly smooth and rich sauce. You can opt for reduced-fat cream cheese if desired.
• Half-and-Half Cream: This gives the sauce its luxurious consistency and velvety mouthfeel, balancing richness without being too heavy.
• Shredded Mozzarella Cheese: Known for its superior melting qualities, mozzarella creates that irresistible gooey top. Be sure to save some for sprinkling over the casserole before baking. Feel free to experiment with other good melting cheeses like Gouda, sharp cheddar, or Gruyère for different flavor notes.
• Simple Seasoning: A blend of garlic powder, onion powder, salt, and freshly ground black pepper enhances the overall savory depth of the casserole. You can use fresh minced garlic cloves if you prefer.

Note: You’ll notice this recipe doesn’t call for chicken broth, or copious amounts of melted or unsalted butter. We rely on the natural flavors of the ingredients and the richness of the cream and cheeses for a truly delightful outcome.

Step-by-Step Instructions: How to Make This Creamy Casserole

Preparing this cheesy broccoli and cauliflower casserole is straightforward. Follow these simple steps for a perfect dish every time:

Detailed Instructions:

1. Preheat Oven and Prepare Steamer: Position your oven rack in the middle, then preheat your oven to a warm 425°F (220°C). While the oven preheats, set up your steaming apparatus. Fill a large pot with approximately 2 cups of water and place a steamer basket inside. Ensure the water level is below the basket.
2. Steam the Vegetables: Bring the water in the pot to a rapid boil. Once boiling, carefully add the cauliflower and broccoli florets into the steamer basket. Cover the pot tightly and steam the vegetables for about 5 minutes. The goal is tender-crisp florets – they should be softened but still have a slight bite, as they will continue to cook in the oven.
3. Prepare the Creamy Cheese Mixture: While your vegetables are steaming, in a large mixing bowl, combine the half-and-half cream, softened cream cheese, diced cooked chicken, 1½ cups of the shredded mozzarella cheese (reserving ½ cup for topping), garlic powder, onion powder, salt, and freshly ground black pepper. Mix everything thoroughly with a spoon or spatula until all ingredients are well combined and a smooth, creamy sauce forms.
4. Combine Vegetables with Sauce: Once steamed, carefully remove the hot cauliflower and broccoli florets from the steamer basket and immediately transfer them into the bowl with the creamy cheese and chicken mixture. There’s no need to cool the vegetables; their warmth will help the cream cheese melt even more smoothly into the sauce. Gently fold the vegetables into the mixture until they are evenly coated.
5. Assemble and Bake the Casserole: Lightly grease a medium-sized baking dish with cooking spray to prevent sticking. Spoon the entire broccoli, cauliflower, and chicken mixture into the prepared casserole dish, spreading it out evenly. Sprinkle the remaining ½ cup of shredded mozzarella cheese over the top.
6. Bake Until Golden and Bubbly: Place the uncovered casserole dish into the preheated oven. Bake for 10-15 minutes, or until the cheese on top is beautifully melted, bubbly, and lightly golden. For an extra golden-brown, slightly crispy cheese topping, you can turn on the broiler for the final 2-3 minutes. Keep a very close eye on it during broiling, as cheese can go from perfectly golden to burnt in a matter of seconds!

Serve your Cheesy Broccoli and Cauliflower Casserole hot and enjoy this comforting, veggie-packed meal!

Make Ahead and Storage Tips

This broccoli and cauliflower casserole is fantastic for meal prepping, offering flexibility for busy schedules. You can prepare it ahead of time in two convenient ways:

Option 1: Partial Prep Ahead

You can steam your broccoli and cauliflower and cook your chicken in advance. Once cooled, store the cooked vegetables and chicken in separate airtight containers in the refrigerator for up to 3-4 days. When you’re ready to assemble, simply combine them with the cheese mixture and bake as directed. This significantly cuts down on active prep time right before dinner.

Option 2: Full Casserole Assembly Ahead

You can assemble the entire casserole, including the cheese mixture, vegetables, and chicken, in your baking dish. Cover it tightly with plastic wrap or foil and refrigerate for up to 24 hours before baking. When ready to bake, you might need to add an extra 5-10 minutes to the baking time since it will be going into the oven cold. Ensure it’s heated through to a safe internal temperature.

Storing and Reheating Leftovers:

• Refrigeration: Once baked and cooled, wrap any leftover casserole tightly with plastic wrap or transfer it to an airtight container. It will keep well in the refrigerator for up to 3 days.
• Reheating in the Oven: For best results, reheat individual portions or the entire casserole in the oven. Preheat your oven to 350°F (175°C). Cover the casserole with aluminum foil to prevent the top from drying out and bake for 15-25 minutes, or until thoroughly heated through. The foil helps maintain moisture and prevents excessive browning.
• Reheating in the Microwave: Individual portions can be quickly reheated in the microwave. Place a serving on a microwave-safe plate, cover loosely, and heat for 1-2 minutes, stirring halfway through, until hot. Be careful not to overheat, which can make the vegetables mushy.
• Freezing: This casserole freezes beautifully! Allow the baked casserole to cool completely. Wrap it tightly in several layers of plastic wrap, then an outer layer of aluminum foil. You can freeze individual portions or the entire dish. It will keep in the freezer for up to 3 months. Thaw overnight in the refrigerator before reheating as instructed above.

This easy and cheesy Broccoli and Cauliflower Casserole Recipe is so simple to make and is the perfect dish for any meal! Made without condensed soup, loaded with vegetables, and made in under 30 minutes, this creamy and cheesy casserole will become a household favorite.

Ingredients

• 1 large head cauliflower cut in small florets
• 1 large head broccoli cut in small florets
• 2 cups cooked chicken breast diced (any boneless, skinless chicken can be used)
• 8 oz cream cheese softened to room temperature
• ½ cup half-and-half cream
• 2 cups mozzarella shredded (save ½ cup for topping)
• ½ tsp garlic powder
• ½ tsp onion powder
• Salt and freshly ground black pepper to taste

Instructions

• Adjust the oven rack to the middle position, and preheat oven to 425°F (220°C). Prepare a steamer by filling a large pot with about 2 cups of water and placing a steamer basket in the bottom.
• Bring the water to a boil. Add the cauliflower and broccoli florets into the steamer basket. Cover the pot and steam for about 5 minutes, until tender-crisp.
• Meanwhile, in a large bowl, combine cooked chicken, cream cheese, half-and-half cream, 1½ cups of mozzarella, garlic powder, onion powder, salt, and freshly ground black pepper. Mix until well combined to form the creamy cheese sauce.
• Remove the steamed cauliflower and broccoli from the heat and transfer them directly into the cream cheese mixture bowl. Gently fold the vegetables into the mixture. Their warmth will help melt the cheese further.
• Grease a casserole dish with cooking spray. Spoon the combined cauliflower, broccoli, and chicken mixture into the oiled casserole dish and spread evenly. Top with the remaining ½ cup of shredded mozzarella cheese.
• Bake uncovered for 10-15 minutes, or until the cheese is melted and bubbly. For a golden-brown top, broil for the final 2-3 minutes, watching carefully to prevent burning. Serve hot.

Recipe Notes

• Any boneless, skinless chicken can be used; this is a great way to use up leftover chicken.
• For a golden-brown cheese topping, broil the casserole for a couple of minutes, keeping a close eye on it.
• Shredding cheese from a block typically yields a smoother, meltier consistency compared to pre-shredded cheese.
• To Store: Once cooled, tightly wrap the casserole or transfer to an airtight container and refrigerate for up to 3 days.
• To Reheat: Reheat in the oven at 350°F (175°C) until warmed through (covered with foil). Can also be reheated in the microwave for individual servings.
• To Freeze: Cool completely, wrap tightly in plastic wrap and foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
