    Instructions
    Step 1: Prepare the Chicken

Thaw chicken thighs safely in the refrigerator. Pat them dry with paper towels.

Season with Italian seasoning, paprika, salt, and black pepper.

Step 2: Prepare the Slow Cooker

Lightly grease the inside of a 6-quart slow cooker.

Arrange the seasoned chicken thighs in a single layer as much as possible.

Step 3: Add the Garlic and Broth

Sprinkle minced garlic and garlic powder over the chicken.

Pour chicken broth around the chicken.

Add onion powder, dried parsley, and optional red pepper flakes.

Step 4: Slow Cook the Chicken

Cover and cook:

  • LOW: 4–5 hours
  • HIGH: 3–4 hours
    Cooking times vary with chicken size and slow cooker model. Cook until the thickest part reaches at least 165°F (74°C).

Step 5: Prepare the Creamy Sauce

About 20–30 minutes before serving, whisk together heavy cream, softened cream cheese, and Parmesan cheese in a bowl.

Stir until smooth.

Step 6: Add the Creamy Mixture

Pour the cream mixture into the slow cooker.

Gently stir the sauce around the chicken without breaking the thighs apart.

Cover and cook on HIGH for another 20–30 minutes until the sauce is hot and creamy.

Step 7: Thicken the Sauce (Optional)

If you prefer a thicker sauce, mix cornstarch with cold water until smooth.

Stir into the slow cooker and cook for another 10–15 minutes until thickened.

Step 8: Garnish and Serve

Sprinkle with fresh parsley, extra Parmesan cheese, and cracked black pepper.

Serve the tender chicken thighs with plenty of creamy garlic Parmesan sauce!

    Frequently Asked Questions (Q&A)
    Q1: Can I put frozen chicken thighs directly into the slow cooker?

No. Frozen raw chicken should not go directly into a slow cooker because it heats too slowly. Thaw it safely in the refrigerator before cooking.

Q2: Can I use bone-in chicken thighs?

Yes! Bone-in thighs work well, but they may require additional cooking time. Always check that the thickest part reaches 165°F (74°C).

Q3: Can I use chicken breasts instead?

Absolutely! Chicken breasts are a leaner alternative. Monitor their temperature carefully to avoid drying them out.

Q4: Can I use milk instead of heavy cream?

Yes, but the sauce will be thinner and less rich. Heavy cream gives the best creamy texture.

Q5: How do I make the sauce thicker?

Mix 1 tablespoon cornstarch with 2 tablespoons cold water and stir into the sauce. Cook until thickened.

Q6: Can I add broccoli or spinach?

Yes! Add broccoli during the final 30–40 minutes or spinach during the final 10–15 minutes.

Q7: Can I prepare this recipe ahead of time?

Yes. Thaw the chicken in the refrigerator and prepare the seasoning mixture ahead. Keep refrigerated until ready to cook.

Q8: Is this recipe keto-friendly?

Yes, it is relatively low in carbohydrates and can fit into many keto-style meal plans.

Q9: Can I make this recipe without cream cheese?

Yes. Increase the heavy cream slightly and add a little extra Parmesan. The sauce will have a different consistency.

Q10: How long do leftovers last?

Store leftovers in the refrigerator for 3–4 days in an airtight container.

Q11: Can I freeze creamy garlic Parmesan chicken?

Yes, although dairy sauces may separate slightly after thawing. Reheat gently while stirring.

Mashed potatoes, steamed broccoli, roasted asparagus, cauliflower rice, pasta, or garlic green beans are excellent choices.
