Ingredients
Serves 4–6
For the Chicken:
-
1½ lbs (700g) boneless, skinless chicken breasts or thighs
-
1 teaspoon salt
-
½ teaspoon black pepper
-
1 teaspoon Italian seasoning
-
1 tablespoon olive oil (optional, for searing)
For the Creamy Garlic Sauce:
-
4–5 cloves garlic, minced
-
1 small onion, finely chopped
-
1 cup (240ml) chicken broth
-
1 cup (240ml) heavy cream
-
½ cup (120g) cream cheese, softened
-
½ cup (50g) grated Parmesan cheese
-
1 tablespoon cornstarch (optional, for thickening)
For the Pasta:
-
12 oz (340g) medium pasta shells
-
Salt for boiling water
-
Fresh parsley for garnish
Step-by-Step Instructions
1. Optional: Sear the Chicken
For extra flavor, heat olive oil in a skillet over medium-high heat. Season chicken with salt, pepper, and Italian seasoning. Sear for 2–3 minutes per side until lightly golden (no need to cook through).
This step adds depth but can be skipped if you’re short on time.
2. Add Ingredients to Slow Cooker
Place chicken into the slow cooker.
Add garlic, onion, chicken broth, heavy cream, and cream cheese. Cover and cook:
-
Low: 4–5 hours
-
High: 2–3 hours
Chicken should be tender and cooked through.
3. Shred or Slice the Chicken
Remove chicken from the slow cooker and shred with two forks or slice into bite-sized pieces.
Return the chicken to the sauce.
4. Cook the Pasta
About 20 minutes before serving, cook pasta shells in salted boiling water until al dente. Drain and set aside.
5. Finish the Sauce
Stir Parmesan cheese into the slow cooker.
If the sauce needs thickening, mix 1 tablespoon cornstarch with 2 tablespoons cold water and stir into the sauce. Let cook on high for 10–15 minutes until thickened.
Add cooked pasta shells and stir gently to coat evenly.
6. Garnish and Serve
Sprinkle with fresh parsley and extra Parmesan. Serve warm.
Tips for the Creamiest Results
Use full-fat dairy
Heavy cream and full-fat cream cheese give the best texture.
Don’t overcook
Chicken breasts can dry out if left too long. Check at the minimum cooking time.
Salt the pasta water well
It enhances overall flavor.
Let it rest 5 minutes before serving
The sauce thickens slightly as it sits.

Storage & Reheating
