Crock Pot Chicken Pasta Recipe: Creamy Garlic Parmesan Sauce

This slow cooker method delivers creamy pasta with minimal effort. The chicken cooks tenderly while the sauce develops rich, garlic-infused flavor throughout the day.

By combining simple ingredients in the crock pot, you achieve restaurant-quality results without constant supervision. The parmesan melts into every bite, creating a velvety texture that coats each noodle perfectly.

The beauty lies in its simplicity: dump, cook, and serve. No pre-cooking required, just layer the ingredients and let the appliance do the work.

What emerges is a comforting, satisfying meal that tastes like it simmered for hours. The garlic and parmesan create a sauce so smooth it feels indulgent.

Ingredients for Crock Pot Chicken Pasta

Simple ingredients transform into a velvety, garlic-infused pasta dish with tender chicken in hours.

The chicken quality matters—opt for thick-cut, even-sized breasts from a trusted butcher or Whole Foods. Pounding to consistent thickness ensures uniform cooking. For the Parmesan, Parmigiano-Reggiano is non-negotiable; pre-grated versions contain anti-caking agents that disrupt the melt. The heavy cream should be full-fat (36-40%) for the creamiest sauce. Most grocery stores carry suitable options in the dairy aisle.

No heavy cream? Half-and-half plus a splash of milk works in a pinch, though the sauce will be thinner. Swap penne for any short pasta—rigatoni or farfalle hold sauce well. For a gluten-free version, brown rice pasta is ideal. The broth can be vegetable if preferred, but chicken adds depth. Better Than Bouillon paste yields superior flavor to canned broths.

Store uncooked chicken in the fridge for up to 2 days or freeze for 9 months. The Parmesan wedge keeps for weeks wrapped in parchment. Leftovers reheat beautifully—add a splash of broth to revive the sauce. Best consumed within 4 days refrigerated.

Step-by-Step Instructions for Crock Pot Chicken Pasta

Here’s the method. Straightforward, tested, works every time.

Step 1: Sear and Season the Chicken

First, pat the 1.5 lb boneless skinless chicken breasts dry and pound them to an even thickness. Season both sides with 1 tsp salt, 0.5 tsp black pepper, and 2 tsp dried Italian seasoning. This ensures even cooking and maximum flavor penetration.

Heat a skillet over medium-high heat with 2 tablespoons of the 0.5 cup unsalted butter. Sear the chicken for 3-4 minutes per side until golden brown. This step locks in juices and adds depth to the sauce. Transfer to the crock pot.

Step 2: Build the Sauce Base

In the same skillet, melt the remaining unsalted butter over medium heat. Add the finely diced yellow onion and cook for 3-4 minutes until translucent. Stir in the 6 cloves minced garlic cloves and cook for 30 seconds until fragrant.

Whisk in the 0.25 cup all-purpose flour and cook for 1 minute to remove the raw taste. Slowly pour in the 1.5 cups chicken broth and 2 cups heavy cream, whisking constantly to avoid lumps. Transfer this mixture to the crock pot over the chicken.

Step 3: Slow Cook to Perfection

Cover and cook on low for 3-4 hours or high for 2 hours. The chicken is done when it reaches 165°F internally and shreds easily with a fork. Remove the chicken, shred it with two forks, and return it to the crock pot.

Stir in the 1.5 cups freshly grated Parmesan cheese until fully melted and combined. The sauce should be creamy and smooth. If it’s too thick, add a splash of chicken broth to reach your desired consistency.

Step 4: Cook and Serve the Pasta

Cook the 12 oz penne pasta separately according to package instructions until al dente. Drain well and add it to the crock pot, stirring to coat evenly with the sauce. Let it sit for 5-10 minutes to absorb the flavors.

Garnish with the 0.25 cup chopped fresh parsley before serving. The parsley adds a pop of color and freshness that cuts through the richness of the dish. Serve immediately while hot.

Dietary Considerations for These Flavors

Gluten-Free Option

Swap 12 oz penne pasta for brown rice pasta or gluten-free penne from Barilla. These hold up well to slow cooking and absorb the creamy sauce beautifully. I’ve tested both with equal success. 🌾

Dairy-Free Adaptation

Replace 2 cups heavy cream with full-fat coconut milk from Thai Kitchen. Use dairy-free parmesan like Violife—it melts surprisingly well. The flavor will be subtly different but still rich and satisfying.

Lower-Calorie Version

Cut calories by using chicken tenderloins instead of breasts and swapping heavy cream for half-and-half. Reduce the butter to ¼ cup and use low-fat parmesan. The dish stays creamy with about 30% fewer calories per serving.

Lactose-Free Adjustments

Use lactose-free heavy cream from Organic Valley and lactose-free parmesan. The texture and taste remain identical to the original. I serve this version to lactose-intolerant friends without anyone noticing the difference.

Vegetarian Alternative

Replace the chicken with 1.5 lb chopped mushrooms or chickpeas. Sauté the mushrooms first to remove moisture, then add to the crock pot with the sauce. The dish stays hearty and flavorful. 💪

Keto Modification

Swap penne pasta for zucchini noodles or shirataki noodles. Use xanthan gum (½ tsp) instead of flour to thicken the sauce. This reduces carbs significantly while keeping the dish creamy and delicious.
