- 12 oz medium pasta shells (uncooked)
Creamy Garlic Parmesan Sauce
- 2 cups low-sodium chicken broth
- 1½ cups heavy cream
- 1 cup freshly grated Parmesan cheese
- 4–5 cloves roasted or minced garlic
- 1 teaspoon Italian seasoning
- ½ teaspoon salt (adjust to taste)
- ½ teaspoon black pepper
Optional Garnishes
- Fresh parsley, chopped
- Extra grated Parmesan cheese
Kitchen Equipment Needed
- Slow cooker (6-quart recommended)
- Mixing bowl
- Whisk
- Tongs or forks (for shredding chicken)
- Measuring cups and spoons
Instructions
Step 1: Prepare the Sauce
In a mixing bowl, whisk together the chicken broth, heavy cream, Parmesan cheese, garlic, Italian seasoning, salt, and black pepper until well combined.
Step 2: Layer the Chicken
Place the chicken breasts in the bottom of the slow cooker in a single layer.
Step 3: Add Pasta and Sauce
Add the uncooked pasta shells over the chicken. Pour the garlic Parmesan sauce mixture evenly over the pasta and chicken.
Make sure the pasta is mostly covered with liquid so it cooks properly.
Step 4: Slow Cook
Cover and cook:
- LOW for 3–4 hours, or
- HIGH for 1½–2 hours
The chicken should be tender and the pasta soft.
Step 5: Shred the Chicken
Remove the chicken from the slow cooker and shred it using two forks. Return the shredded chicken to the slow cooker and stir gently so everything is coated in the creamy sauce.
Step 6: Serve
Let the dish rest for about 5 minutes to allow the sauce to thicken slightly. Garnish with fresh parsley and extra Parmesan before serving.
Storage
Refrigerator:
Store leftovers in an airtight container for up to 4 days.
Freezer:
Freeze portions for up to 2 months.
Reheating:
Warm on the stovetop or microwave with a small splash of milk or broth to loosen the sauce.
Frequently Asked Questions
Can I use chicken thighs instead of chicken breasts?
Yes. Chicken thighs work very well and provide extra richness and tenderness.
Can I use another type of pasta?
Medium pasta shells work best, but penne or rotini can also be used. Avoid very large pasta shapes that may not cook evenly.
Can I add vegetables?
Absolutely. Spinach, mushrooms, or broccoli are great additions.
How can I make it lighter?
Use half-and-half instead of heavy cream and reduce the Parmesan slightly.
Conclusion
Slow Cooker Creamy Garlic Parmesan Chicken Shells is the perfect comfort meal for busy days. With tender chicken, perfectly cooked pasta, and a rich garlic Parmesan sauce, this dish delivers restaurant-style flavor with minimal effort.
