In a small bowl, mix garlic powder, onion powder, salt, and pepper. Season chicken on both sides.
In a large skillet heat oil and butter over medium high. Sear chicken on both sides until well browned.
Add Better Than Bouillon to hot water and whisk until combined. Use a small amount to deglaze your skillet scraping up any browned bits.
Whisk remaining bouillon water mixture with cornstarch and pour into slow cooker.
Stir in garlic, Italian seasoning, paprika, salt, pepper, and red pepper flakes.
Add in chicken breasts including any leftover butter/oil/broth mixture from the pan. Top with sun dried tomatoes. Cook on low for 6-8 hours.
Around 30 minutes before chicken is done stir in heavy cream. After chicken is done remove from slow cooker and stir in cheese. Serve chicken with sauce on its own or over rice or pasta. Enjoy!
