Cook the penne pasta in salted water until al dente, according to package instructions, then drain.
In a large skillet, cook the chopped bacon over medium heat until crispy. Remove and set aside.
In the same skillet, add the diced chicken and season with salt and pepper to taste. Cook until browned and fully cooked through, about 6-8 minutes.
Pour in the chicken broth and bring to a simmer, scraping up any browned bits from the bottom of the pan.
Stir in the heavy cream and ranch seasoning mix, mixing thoroughly.
Add the cherry tomatoes and cooked pasta into the skillet, tossing everything gently to combine.
Fold in the shredded cheddar cheese until melted and creamy throughout the dish.
Taste and adjust seasoning as necessary with salt and pepper, then garnish with chopped parsley before serving.
