Why YOU will love this recipe

Ingredients

Find the full ingredient list, with measurements, in the recipe card below.

• Broccoli + cauliflower florets – You can use either fresh broccoli and fresh cauliflower or frozen.
• Cream cheese – Based on my firsthand experience, this is all you need to create a creamy sauce. Forget the canned soup!
• Shredded cheese – We like using marble cheddar cheese but sharp cheddar cheese, parmesan, gouda, gruyere, and mozzarella cheeses all work well too.
• Garlic powder – This adds a punch of flavor to the sauce. You could also substitute onion powder.
• Fine sea salt – A pinch of salt is essential to bring out the flavors of your ingredients.
• Black pepper – The slightly spicy flavor helps to balance the creaminess.

Equipment

• Saucepan – For steaming the vegetables.
• Mixing bowl – Only one large mixing bowl is needed.
• Spatula or spoon – We love using these little spatulas for stirring. They are one of our favorite and most used kitchen tools.
• Casserole dish – Use an 8×8 or 9×9 ceramic baking dish.

Then, add about 2 inches of water to the large pot, set it over medium-high heat, and bring the water to a quick boil. Once the water is bubbling, add the cauliflower and broccoli florets.

The warm vegetables will create a delicious cheese sauce from the melting cream cheese.
