This 5-ingredient slow cooker garlic Parmesan chicken pasta is my weeknight ace-in-the-hole when I need to feed a hungry crowd without hovering over the stove. Boneless chicken simmers low and slow in a creamy, garlicky Parmesan sauce, then gets tossed with delicate angel hair pasta so every strand is glossy and well-coated. While it’s a very American, budget-friendly spin on Alfredo-style pasta, the technique borrows from classic Italian approaches: cook the protein gently, enrich the sauce with cheese and starch, and let the pasta finish in the sauce so it drinks up all that flavor.
Serve this rich, creamy chicken pasta with something crisp and fresh to balance it out: a simple green salad with a sharp vinaigrette or some steamed broccoli tossed with lemon juice works beautifully. Warm garlic bread or a crusty baguette helps scoop up the extra sauce from the slow cooker. If you enjoy wine, a light, zippy white such as Pinot Grigio or Sauvignon Blanc cuts through the richness nicely, while sparkling water with lemon keeps things family-friendly and refreshing.
5-Ingredient Slow Cooker Garlic Parmesan Chicken Angel HairServings: 6
Ingredients
2 pounds boneless, skinless chicken breasts (or thighs)
1 (22–24 ounce) jar garlic Parmesan pasta sauce
1 cup low-sodium chicken broth
12 ounces angel hair pasta, dry
1 cup grated Parmesan cheese, plus extra for serving
Directions
Add the chicken: Place the boneless, skinless chicken breasts (or thighs) in the bottom of a 5- to 6-quart slow cooker in an even layer so they cook at the same rate.
Build the base sauce: Pour the jar of garlic Parmesan pasta sauce evenly over the chicken. Add the chicken broth around the sides and gently shake or stir just enough so the liquids mingle without completely uncovering the chicken.
Slow cook the chicken: Cover and cook on LOW for 3 1/2 to 4 1/2 hours, or on HIGH for 2 to 3 hours, until the chicken is very tender and easily shreds with a fork. Slow cookers vary, so start checking toward the earlier end of the range.
Shred the chicken: Once the chicken is done, use two forks to shred it directly in the slow cooker into bite-size pieces, stirring to coat it thoroughly in the creamy garlic Parmesan sauce.
Prepare the angel hair: About 10 minutes before you’re ready to serve, break the angel hair pasta in half so the strands fit comfortably in the slow cooker and are easier to toss and serve.
Cook the pasta in the slow cooker: Turn the slow cooker to HIGH if it isn’t already. Stir the broken angel hair into the hot sauce and shredded chicken, pressing the pasta down so it’s mostly submerged in the sauce. Cover and cook for 10 to 15 minutes, stirring once or twice, just until the angel hair is al dente and has absorbed some of the sauce. The mixture should look glossy and a bit loose—remember, the pasta will keep absorbing as it sits.
Finish with Parmesan: Turn off the slow cooker. Sprinkle the grated Parmesan cheese over the pasta and toss gently but thoroughly until the cheese melts and the sauce clings to every strand in a rich, pale coating. If the mixture seems too thick, stir in a splash of hot water or additional warm broth, a tablespoon at a time, until the strands pull apart easily and remain glossy.
Rest and serve: Let the pasta rest, covered, for 3 to 5 minutes so the sauce settles and thickens slightly. Give it one last toss, then serve straight from the slow cooker, twirling generous scoops into bowls and topping with extra Parmesan if you like.
Variations & Tips
For extra vegetables without adding much prep time, stir in a 10- to 12-ounce bag of frozen peas, broccoli florets, or mixed vegetables during the last 15 to 20 minutes of cooking, before adding the pasta, so they heat through. If you prefer a bit of heat, add a pinch of red pepper flakes to the sauce before cooking the chicken. To lighten things up, use reduced-fat garlic Parmesan sauce and cut the Parmesan cheese back to 3/4 cup, adding a splash more broth if needed to keep the pasta glossy. You can also swap in whole-wheat angel hair for more fiber; just know it can take a few extra minutes to soften in the slow cooker. For a slightly more indulgent version (and if you don’t mind a sixth ingredient), finish with a tablespoon or two of butter at the end for an even silkier sauce. Food safety tips: Always start with fully thawed chicken; frozen chicken can stay too long in the temperature “danger zone” in a slow cooker. Use a thermometer if you’re unsure—chicken should reach 165°F in the thickest part. Keep the slow cooker covered while cooking to maintain a safe, steady temperature, and refrigerate leftovers within 2 hours in shallow containers. Leftovers reheat well; add a splash of water or broth before reheating to loosen the sauce and restore that glossy texture.
