2. Ingredients for Slow Cooker Cheesy Chicken Alfredo
This recipe uses simple ingredients to create a rich, creamy dish:
- 1 1/2 lbs boneless, skinless chicken breasts (about 2-3 breasts)
- 4 cups chicken broth (low-sodium recommended)
- 1 cup heavy cream
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1/2 cup cream cheese (cubed, for extra creaminess)
- 3 cloves garlic, minced
- 8 oz fettuccine pasta (or any pasta of choice)
- Salt and pepper to taste
- Chopped fresh parsley (for garnish, optional)

3. Step-by-Step Instructions for Making Cheesy Chicken Alfredo
Step 1: Prepare the Slow Cooker and Add Ingredients
- In the slow cooker, place the chicken breasts and season with salt and pepper.
- Add the chicken broth and minced garlic. Stir gently to combine.
Step 2: Slow Cook the Chicken
- Cover and cook on LOW for 4-5 hours or HIGH for 2-3 hours, until the chicken is tender and fully cooked.
Step 3: Shred the Chicken
- Remove the chicken from the slow cooker and shred it with two forks. Return the shredded chicken to the slow cooker.
Step 4: Add the Cheeses and Cream
- Add the heavy cream, mozzarella cheese, Parmesan cheese, and cream cheese to the slow cooker.
- Stir well to combine and allow the cheeses to melt into the sauce.
Step 5: Add the Pasta
- Break the fettuccine pasta in half and add it to the slow cooker. Stir to make sure the pasta is submerged in the sauce.
Step 6: Continue Cooking
- Cover and cook on HIGH for 20-30 minutes, stirring halfway through, until the pasta is tender and cooked through. Check the pasta after 15 minutes to ensure it doesn’t overcook, as different slow cookers can vary.
Step 7: Serve and Garnish
- Once the pasta is cooked, stir everything well to coat the pasta in the creamy sauce. Serve warm, garnished with fresh parsley if desired.
4. Tips for the Perfect Cheesy Chicken Alfredo
Using the Right Pasta
Long pasta, like fettuccine, works well, but you can also use penne or rotini for a more bite-sized pasta. Be sure to stir halfway through to prevent the pasta from sticking together.
Adjusting Creaminess
For an extra creamy sauce, add more cream cheese or heavy cream. If you prefer a lighter sauce, use half-and-half instead of heavy cream.
Preventing Overcooked Pasta
Add pasta toward the end of the cooking time and check for doneness frequently, as pasta can cook quickly in the slow cooker.
Adding Vegetables
Feel free to add fresh or frozen spinach, steamed broccoli, or peas during the last 15 minutes for extra flavor and nutrition.

5. Variations to Try
Spicy Chicken Alfredo
Add 1/4 tsp red pepper flakes and a dash of hot sauce for a spicy twist. Pepper jack cheese is also a delicious substitute for mozzarella if you like extra heat.
Garlic Parmesan Shrimp Alfredo
Swap the chicken for shrimp, adding them during the last 20 minutes of cooking. Shrimp cook quickly and pair beautifully with the garlic-Parmesan Alfredo sauce.
Bacon and Mushroom Alfredo
Add 1/2 cup cooked, crumbled bacon and sautéed mushrooms during the last 15 minutes of cooking for a rich, earthy flavor.
Italian Herb Alfredo
Add a teaspoon of Italian seasoning or fresh basil to the sauce for an Italian-inspired twist that adds aromatic flavor.
6. Serving Suggestions
Cheesy Chicken Alfredo is hearty on its own, but here are a few ideas to complete your meal:
- Garlic Bread: Serve with crusty garlic bread or breadsticks to scoop up the creamy sauce.
- Caesar Salad: A crisp Caesar salad with romaine, croutons, and Parmesan adds a refreshing contrast.
- Roasted Vegetables: Roasted asparagus, zucchini, or bell peppers make a light, healthy side dish.
- Simple Green Salad: A salad with mixed greens, tomatoes, and a light vinaigrette balances the richness of the Alfredo.

FAQs
1. Can I use pre-cooked chicken for this recipe?
Yes! If using pre-cooked chicken, add it to the slow cooker in the last hour so it doesn’t overcook.

Absolutely. Substitute with about 2 cups of jarred Alfredo sauce to save time, adding it along with the cheeses and cream.
3. Can I make this recipe gluten-free?
Yes! Use gluten-free pasta and ensure your chicken broth is gluten-free.
