Ingredients You’ll Need
This Broccoli and Cauliflower Casserole Recipe relies on a few simple, high-quality ingredients that work harmoniously to create layers of flavor and texture. Each one brings something special to the table—whether it’s the mild nuttiness of the cauliflower, the bright freshness of broccoli, or the creamy richness from the cheeses and chicken.
- Cauliflower, large head: Using small florets ensures even steaming and a tender base for the casserole.
- Broccoli head: Just like the cauliflower, small florets keep the texture consistent and add a vibrant green pop.
- Cooked chicken breast, 2 cups diced: Adds a savory protein punch that makes this casserole a hearty meal.
- Cream cheese, 8 oz softened: Gives the casserole its luxuriously creamy foundation and binds everything together.
- Half-half cream, ½ cup: Adds smoothness and richness without being overly heavy.
- Mozzarella cheese, 2 cups shredded (plus extra for topping): Melts beautifully, offering gooey texture and mild flavor that complements the vegetables perfectly.
- Garlic powder, ½ tsp: Brings a warm aromatic note that elevates the whole dish.
- Onion powder, ½ tsp: Adds subtle depth without overpowering the other ingredients.
- Salt and freshly ground black pepper: Essential for seasoning and balancing flavors throughout the casserole.
How to Make Broccoli and Cauliflower Casserole Recipe
Step 1: Preparing Your Oven and Steaming the Veggies
Start by adjusting your oven rack to the center position and preheat your oven to 425°F. While that’s heating up, prepare your vegetables by steaming the cauliflower and broccoli florets. Steaming them until just tender (about five minutes) keeps their texture firm enough to hold up in the casserole while making them perfect partners for the creamy cheese mixture.
Step 2: Mixing the Creamy Chicken and Cheese Base
In a large bowl, combine your diced cooked chicken breast with the softened cream cheese, half-half cream, and shredded mozzarella. Season everything with garlic powder, onion powder, salt, and freshly ground black pepper. This step is where all the flavors start to marry, creating that irresistible creamy base for your broccoli and cauliflower.
Step 3: Combining the Veggies and Chicken Mixture
Right after steaming, add your hot cauliflower and broccoli directly into the cheese and chicken mixture. There’s no need to wait for them to cool since the warmth helps melt the cheese and blend all the ingredients beautifully. Gently fold everything together so the vegetables are evenly coated with that luscious cheesy goodness.
Step 4: Assembling and Baking the Casserole
Oil your casserole dish to prevent sticking, then spoon in the broccoli and cauliflower mixture. Sprinkle the reserved mozzarella cheese generously on top for that irresistible golden, bubbly crust. Bake uncovered for 10 to 15 minutes until the cheese on top is fully melted and your kitchen starts filling with a tantalizing aroma.
Step 5: Optional Broiling for a Beautiful Finish
If you like a slightly browned and crispy cheese topping, switch your oven to broil on high and place the casserole under the broiler for about 3 minutes. Keep a very close eye during this step to avoid burning. This little touch adds a wonderful texture contrast and makes your casserole look spectacular.

Garnishes
While this casserole is fantastic on its own, a sprinkle of freshly chopped parsley or chives can add a lovely burst of color and a mild herbal freshness that brightens every bite. If you’re feeling adventurous, a few red pepper flakes on top will introduce a subtle heat that contrasts beautifully with the creamy cheese.
Side Dishes
This Broccoli and Cauliflower Casserole Recipe pairs great with a variety of sides. Consider serving it alongside a crisp green salad for some refreshing crunch or a light tomato and cucumber salad for acid balance. Roasted potatoes or warm crusty bread also complement the creamy texture of this dish perfectly if you want something more substantial.
Creative Ways to Present
For a fun twist, try serving this casserole in individual ramekins for individual portions that look elegant and inviting. You could also scoop it into bell pepper halves or hollowed zucchini boats for an appetizing presentation that will wow your guests and add some extra vegetable goodness.
Make Ahead and Storage
Storing Leftovers
After enjoying this Broccoli and Cauliflower Casserole Recipe, store any leftovers in an airtight container in the refrigerator. The casserole will stay fresh for up to 3 to 4 days, making it an excellent option for quick lunches or reheating for dinner later in the week.
Freezing
If you want to save a portion for even longer, this casserole freezes beautifully. Portion it out into freezer-safe containers or wrap the entire casserole tightly with plastic wrap and aluminum foil. It will maintain good quality for up to 2 months. When planning ahead, freezing can be a real lifesaver for busy days.
Reheating
To reheat, thaw frozen portions overnight in the fridge if possible, then warm the casserole in the oven at 350°F until heated through and bubbly again. You can also microwave individual servings, though the oven helps retain that delicious baked texture and cheese melt. Reheating is easy and just as comforting as the first time!
FAQs
Can I make this casserole vegetarian?
Absolutely! Simply omit the cooked chicken breast and increase the amount of cheese or add in some sautéed mushrooms for a hearty vegetarian version that’s just as satisfying.
What can I substitute for half-half cream?
If you don’t have half-half cream on hand, whole milk combined with a small amount of melted butter works well to replicate the richness and texture needed in the recipe.
Is it okay to use frozen broccoli and cauliflower?
Yes, you can use frozen florets—just make sure to thaw and drain them thoroughly to avoid extra moisture that could make the casserole watery.
Can I use different types of cheese?
Definitely! Feel free to experiment with cheeses like sharp cheddar, Gruyère, or Monterey Jack for a different flavor profile. Just keep the total amount roughly the same to maintain creaminess.
How long do I need to steam the vegetables?
Steaming for about 5 minutes until the vegetables are tender but still firm is ideal. Over-steaming can make them mushy and affect the texture of your casserole.

Instructions
- Preheat the oven: Adjust the oven rack to the middle position and preheat your oven to 425°F (220°C) to prepare for baking the casserole.
