Preheat the oven to 350. Spray a 9 x 13 baking dish with cooking spray.
Mix seasonings with cream cheese, sour cream, mayo, and half the cheese.
Fold in the broccoli. Spread in the prepared casserole dish. Top with the remaining cheese.
Bake until hot, about 20 min.
Substitutions: You can swap the cheddar cheese for mozzarella or any other cheese that melts well. Cauliflower works well in place of or in addition to the broccoli. Additions: Feel free to add in some crumbled bacon, cooked chicken, cooked turkey, cauliflower rice, other steamed veggies, etc. This base cheese sauce is great on so many things!Frozen Broccoli: In a pinch, you can sub in frozen broccoli. Cook according to the package and drain it well before adding it.Prep Time: Steam the broccoli and put everything in the casserole dish. Set in the fridge until you are ready to bake. To Reheat: You quickly can reheat the leftovers in the microwave for 1 - 2 minutes or until hot. Another option is to warm it in the oven at 350 degrees for 10-15 minutes. Once heated through and the cheese has melted, you can serve. To Freeze: Either freeze the entire batch of broccoli casserole in a large freezer-safe container or in individual servings. It’s best to thaw the broccoli casserole in the fridge before warming up.
