A delightful and easy-to-make cheesy broccoli casserole that is perfect for any meal.
Preheat your oven to 350°F (175°C).
Ensure the oven is fully preheated before placing the dish inside for even cooking.
In a mixing bowl, combine the frozen broccoli, garlic powder, and ground black pepper.
Toss the broccoli well to evenly coat it with the seasonings.
Transfer the seasoned broccoli into a casserole dish.
Spread the broccoli evenly to ensure uniform baking.
In the same mixing bowl, mix the shredded cheddar cheese, mayonnaise, and Dijon mustard until well combined.
Mix thoroughly to create a smooth and creamy topping.
Spread the cheese mixture evenly over the broccoli in the casserole dish.
Ensure the topping covers all the broccoli for a consistent flavor.
Bake the casserole in the preheated oven for 20 minutes, or until the cheese is bubbly and golden.
Check the casserole halfway through to ensure it doesn't overcook.
Remove from the oven and let it cool slightly before serving.
Allowing the casserole to cool helps the flavors meld together.
