Ingredients

  • 6 cups broccoli florets
  • 5 slices bacon chopped
  • 2 tablespoons butter
  • 1/2 cup onion diced
  • 2 cloves garlic minced
  • 3/4 cup heavy whipping cream
  • 3/4 cup mozzarella cheese
  • 1/4 cup parmesan cheese grated
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 1/4 teaspoon xanthan gum optional

Instructions

  • Steam the broccoli until bright green but still has a bit of crunch to it. About 3 minutes in the microwave in a bowl with 1/4 cup of water and covered tightly with plastic wrap.
  • Fry the bacon in a skillet until crisp. Set the bacon aside and remove all but 1 tbsp of bacon fat.
  • Add the butter, onions, and garlic and sautee until the onion is translucent. About 5 minutes at medium high heat.
  • Add the cream to the skillet and simmer for 2-3 minutes to thicken slightly. Thicken with xanthan gum if you like.
  • Return the bacon to the pan and add the parmesan cheese. Combine well. Add the drained and steamed broccoli and stir to coat. Season with salt and pepper.
  • Put the broccoli and cream mixture into a casserole dish. Top with the mozzarella cheese and bake at 400-F for about 5 minutes until hot and bubbly and the cheese is golden brown. Serve!

Notes

Recipe Card Tips

  • Don't overcook the broccoli, steam it just until bright green with some crunch left.
  • Reserve the bacon fat after frying, and use it along with butter to sautee the onion and garlic for extra flavor.
  • Use xanthan gum sparingly, no more than 1/4 teaspoon, if you want a slightly thicker sauce.
