Bring a large pot of well-salted water to a boil. Cook the fettuccine until al dente according to package instructions. Reserve 1/2 cup of the pasta water, then drain and return pasta to the pot.
While the pasta cooks, heat a large skillet over medium heat. Add the chopped turkey bacon and cook until crisp, about 5 minutes.
Add the garlic to the skillet and cook for 30 seconds to 1 minute, until fragrant. Transfer the bacon and garlic to a bowl and discard excess fat, leaving a thin layer in the pan.
Increase heat to medium-high and add the chicken strips to the skillet. Season generously with salt and pepper. Cook, turning once, until cooked through and lightly golden, about 8 to 10 minutes.
Reduce heat to low. Return the turkey bacon mixture to the skillet, then add the cooked pasta. Toss gently to combine.
In a bowl, whisk together the eggs, Parmesan cheese, and parsley. Season lightly with salt and pepper.
Remove the skillet from direct heat. Pour the egg mixture over the pasta and toss quickly to coat.
Add reserved pasta water a tablespoon at a time, tossing constantly, until the sauce becomes creamy and glossy.
Taste and adjust seasoning if needed.
Serve immediately, garnished with extra Parmesan and parsley.
