Brown your bacon. The longer you cook the bacon the crispier it will be.
Once the bacon has cooked, remove and allow to drain on a paper towel.
Leave the bacon grease in the pan and sautee your onions for about 3 minutes until they are soft and translucent.
Next, add in your broccoli and garlic. Allow to cook for 3-5 minutes until the broccoli is vibrant in color and is tender.
Reduce your heat to low and pour in the heavy cream. Simmer for 3-5 minutes, until the sauce has thickened.
Add in the cooked bacon.
Top with the shredded mozzarella cheese. Allow the cheese to melt for a few minutes. If you prefer, you could stick the skillit in the oven under the broiler to melt the cheese to a light golden brown.
Optional to top with crushed red pepper flakes.
