01 - Bring a large pot of salted water to a boil. Cook pasta according to package directions until al dente, approximately 8-10 minutes. Reserve 1/2 cup of pasta water before draining. Set pasta aside.
02 - Heat a large skillet over medium heat. Add chopped beef bacon and cook until crispy and fat has rendered, about 5-6 minutes. Remove bacon with a slotted spoon and drain on paper towels. Pour off all but 1 tablespoon of bacon fat from the skillet.
03 - Pat diced chicken dry with paper towels. Season evenly with smoked paprika, garlic powder, onion powder, salt, and black pepper, tossing to coat all pieces.
04 - In the same skillet with reserved bacon fat, add butter and seasoned chicken. Sauté over medium-high heat for 4-5 minutes until golden brown and cooked through, reaching an internal temperature of 165°F. Add minced garlic during the last minute of cooking, stirring constantly until fragrant.
05 - Reduce heat to medium-low. Add softened cream cheese and heavy cream to the skillet, whisking continuously until completely smooth and melted. If sauce appears too thick, incorporate reserved pasta water 1 tablespoon at a time until desired consistency is achieved.
06 - Stir in grated sharp cheddar cheese, continuing to mix until fully melted and incorporated into the sauce. The sauce should be glossy and coat the back of a spoon.
07 - Add cooked pasta to the skillet, tossing thoroughly to coat evenly with sauce. Stir in spring onions, half the crispy beef bacon, and half the fresh herbs. Divide among serving plates and top with remaining beef bacon and herbs. Serve immediately while hot.
