Spiralize the zucchini into thin noodles and pat them thoroughly with paper towels to remove excess moisture.
In a small bowl, whisk the egg and grated parmesan cheese together until well combined and set aside.
Dice the bacon and cook in a large skillet over medium heat until crispy, then remove the bacon bits and drain on a paper towel.
Add the olive oil to the same skillet and sauté the chicken breast pieces until golden brown and cooked through.
Add the minced garlic to the skillet and sauté for 30 seconds until fragrant.
Add the zucchini noodles to the skillet and toss for 1-2 minutes until they are just tender but still have a slight crunch.
Turn off the heat and remove the skillet from the burner to prevent the eggs from scrambling.
Quickly pour the egg and cheese mixture over the noodles, tossing constantly to create a smooth, creamy sauce.
Fold in the crispy bacon, season with sea salt and black pepper, and serve immediately while warm.
