Add 1 Tablespoon minced garlic, ½ cup chopped sun dried tomatoes, 3 Tablespoons tomato paste, 1 1/2 teaspoons onion powder, 1 teaspoon Italian seasoning, ½ teaspoon paprika and 1/8 teaspoon black pepper to a 5-6 quart crock pot.
Pour in 2 (32 ounce) cartons chicken broth and use a whisk to combine.
Cover and set the crockpot to high until it’s boiling (this can take about 2 hours (some will take longer and some will be much faster depending on the type and brand you own.)
Stir in 8 ounces uncooked medium shell pasta and cook until al dente. Approximately 12-25 minutes (again, this will be based on the type and brand of slow cooker you own.) Make sure to replace the lid and stir occasionally.
Stir in 4 teaspoons fresh basil, chopped, 8 ounce block cream cheese, softened and cut into cubes, 1 cup heavy whipping cream, ½ cup shredded parmesan cheese and 2 cups shredded rotisserie chicken. Cover. Be sure to stir occasionally until the cream cheese and parmesan are fully melted, and the chicken is heated through. Approximately 5-10 minutes.
At this point you can turn the slow cooker to a warm setting until you are ready to serve (it can stay on the warm setting for 3-4 hours.) Serve garnished with additional parmesan and fresh chopped basil.
Notes
If you prefer, you can cook the shells separately and skip step 3. Add the cooked pasta to the slow cooker along with the chicken, cream cheese, cream, sun dried tomatoes, etc. Cover and cook. Stir occasionally until the cream cheese is melted and fully incorporated.
See post above (Frequently Asked Question section) for directions on how to make this on the stovetop or how to use fresh chicken instead of rotisserie chicken.
