Method
Preparation
- In a cold large cast iron skillet, add bacon. Turn heat to medium and cook until crisp, about 25 minutes.
- Remove bacon and set aside. Pour bacon drippings into a jar for later use and return 4 tablespoons to the pan.
- Add mushrooms, onion, and garlic to the skillet and cook until browned, about 5 minutes.
- Add 2 tablespoons of bacon drippings, flour, salt, pepper, and red pepper flakes. Stir until flour dissolves; cook for 1 minute.
- Add milk and stir to combine. Remove from heat and add cheese a handful at a time, stirring until melted.
- Mix in green beans and half of the cooked bacon. Return to medium heat and cook until heated through and sauce thickens, about 3 to 5 minutes.
- Top with remaining bacon.
Notes
To store in the fridge, let the casserole cool to room temperature. It will keep for 3 to 4 days in an airtight container. You can also freeze it for up to 2 months.
