Cut raw bacon into chunks and fry up in a pan over medium-high heat until thoroughly cooked. Once cooked, remove from heat and drain grease. Allow the bacon to cool on a paper towel; set aside.
Using the same frying pan heat 1-2 tablespoons of olive oil over medium-high heat, then add onion and season with salt and pepper. Cook over heat, stirring occasionally, until caramelized, about 15-20 minutes. Remove from heat and cool.
Finely chop cooled bacon and add to a large mixing bowl.
Add cream cheese, sour cream, Gruyère, thyme and red pepper flakes, Beat until well combined.
Stir in cooled onions, until completely mixed in.
Form the cheese mixture into a ball and wrap in plastic wrap to chill for at least 1 hour.
*TIP* I set the cheese mixture in the center and on top of two pieces of plastic wrap. Then gently pull the plastic wrap together to form a ball. Then using my hand I gently press the plastic wrap to make a ball.
In a small bowl combine chives and French's Crispy Fried Onions, toss to combine.When ready to serve, remove the cheese ball from the fridge and roll it in the fried onion and chive mixture.
Serve with crackers, chips or baguette slices.
