Begin by seasoning your chicken breasts generously with salt and pepper, ensuring each piece is well-coated to enhance flavor. Place the seasoned chicken in the bottom of your crockpot, arranging it in a single layer.

In a medium bowl, combine freshly grated Parmesan cheese, heavy cream (or coconut cream), minced garlic, dried herbs, and chicken broth. Whisk until well blended.

Carefully pour the creamy sauce mixture over the chicken in the crockpot, ensuring to cover all pieces evenly. Sprinkle sun-dried tomatoes on top if using.

Cover the crockpot and cook on low for 4 to 5 hours until the chicken is tender and easily pulls apart.

To thicken the sauce, whisk a small amount of cornstarch with cold water and stir into the sauce during the last 10 to 15 minutes of cooking.

Once cooked, remove the lid and gently stir. Serve warm, garnished with fresh herbs or lemon juice. Pair with risotto or garlic mashed potatoes.
