  • 1 Pound Broccoli Flourets
  • 3 Cups Shredded Cheddar Cheese, divided
  • 1 Cup heavy whipping cream
  • 1 teaspoon Mustard Powder
  • 2 cloves Garlic, minced
  • 1 Pound Bacon, cooked and crumbled
  • Kosher salt and pepper to taste


Cheese Sauce:

  • In a heavy bottom sauce pan, heat your cream over medium heat.
  • Add your mustard powder and minced garlic. Let cook for a few minutes.
  • Add 2 cups of the shredded cheddar cheese to the cream mixture. Turn heat down to low and whisk until melted completely. Remove from the heat and set aside.
  • Salt and pepper to taste.

Assembling the Casserole:

  • Take your broccoli florets and place them in a microwave safe bowl with a little water. Add 1 tsp of salt and place in microwave for about 2 minutes. Just enough to take the crispiness out of the broccoli. Set aside.
  • Preheat your oven to 400F.
  • Spray a 9x13 casserole dish with cooking spray. Add the broccoli to the casserole dish, covering the bottom of the dish. Then add your crumbled bacon, making a layer on top. Leaving some aside for garnish.
  • Pour the cheese sauce evenly on top of the broccoli and bacon. Sprinkly the remaining 1 cup shredded cheddar cheese on top of the casserole. Add your left over bacon on top as garnish.
  • Place the casserole dish in the preheated oven and bake for 20 minutes. Serve.


  • Bacon - I uses a thin bacon that was 50 calories per slice.  
  • How to make this with chicken - I think using a rotisserie chicken and mixing in the the cooked chicken with the broccoli before adding in the cheese sauce would be delicious.  You could also cook 2 chicken breast and shred them for the casserole.
  • Can this be made with frozen broccoli? - This is best with fresh broccoli but frozen can definitely be used.  Let the broccoli thaw, but do not steam it before baking it in the casserole.
