Step 1 Cook the Chicken Base - Place the chicken breasts in the bottom of your slow cooker. Sprinkle the salt, black pepper, Italian seasoning, and garlic powder evenly over the chicken. Take a moment to gently rub the seasoning in so every bite gets flavor.
Step 2 Add the Creamy Sauce Ingredients - Pour in the chicken broth and heavy cream. Add the chopped sun dried tomatoes and red pepper flakes. Give the liquid a gentle stir so everything is evenly distributed around the chicken.
Step 3 Add the Cream Cheese - Scatter the cubed cream cheese over the top of the chicken and sauce. Do not stir yet. It will melt down beautifully as it cooks.
Step 4 Slow Cook Until Tender - Cover and cook on low for 3 to 4 hours, until the chicken is tender and shreds easily with a fork. This is where the magic happens and your kitchen starts smelling like something special.
Step 5 Shred and Return the Chicken - Remove the chicken from the slow cooker and shred it using two forks. Return the shredded chicken to the slow cooker and stir it into the sauce.
Step 6 Add the Ravioli and Parmesan - Stir in the frozen cheese ravioli and shredded Parmesan cheese. Gently fold everything together so the ravioli are coated in that creamy sauce.
Step 7 Finish Cooking the Ravioli - Cover and cook for another 30 to 40 minutes, until the ravioli are tender and heated through. Give it a final gentle stir and let it rest for a few minutes so the sauce can thicken.
