Step 1: Season And Layer The Chicken - Place the chicken breasts in the slow cooker in an even layer. Sprinkle over the salt, pepper, garlic powder, and onion powder. This simple seasoning gives the chicken a good flavor base before the barbecue sauce goes in. Pour over the barbecue sauce and chicken broth, then gently stir around the chicken just enough to blend the sauce. Scatter half the bacon over the top. That bacon starts infusing flavor right from the beginning.
Step 2: Let The Slow Cooker Work - Cover and cook on low for 4 to 6 hours or high for 3 to 4 hours until the chicken is fork tender. This is where the magic happens. The chicken slowly absorbs all that smoky sweet sauce and becomes incredibly juicy. I always say low and slow gives you the best texture if you have the time.
Step 3: Shred The Chicken Into The Sauce - Remove the cooked chicken to a plate and shred it with two forks. It should pull apart easily. Return all that shredded chicken back to the slow cooker and stir it into the sauce so every strand gets coated. At this point it already smells amazing.
Step 4: Add The Tortellini And Cream - Stir in the refrigerated cheese tortellini gently so you do not tear them. Pour in the heavy cream and give it another soft stir. This is where it starts transforming from barbecue chicken into a creamy comforting pasta dinner.
Step 5: Melt In The Cheese - Add 1 cup of the shredded cheddar and stir until melted into the sauce. Cover and cook on high another 20 to 30 minutes until the tortellini is tender and heated through. Keep an eye on it toward the end because you want tender tortellini, not mushy.
Step 6: Finish With Bacon And More Cheese - Let it sit a few minutes to thicken up. Then top with the remaining cheddar and the rest of that crumbled bacon. That final layer makes it feel a little extra special. Scoop it up while it is hot and creamy.
