This slow cooker 3-ingredient creamy chicken pasta is the kind of weeknight trick my aunt swears by: you literally dump three things into the pot, walk away, and come back to a rich, glossy sauce clinging to every tender noodle. It leans on the convenience foods many of us grew up with in the Midwest—bottled Alfredo sauce and dry pasta—but uses the slow cooker’s gentle heat to turn boneless chicken into juicy shreds that melt into the sauce. If you’re juggling work, kids, or a long commute, this is the sort of hands-off, comfort-heavy dinner that quietly does its job in the background while you get on with your day.
Serve this creamy chicken pasta straight from the slow cooker or mounded onto warm plates, where the steam and glossy sauce really shine. A simple green salad with a sharp vinaigrette or some steamed broccoli helps cut the richness nicely. If you have time, warm up a loaf of crusty bread or garlic toast to swipe through any extra sauce. A crisp white wine, like Pinot Grigio, or even sparkling water with lemon balances the creamy texture. Leftovers reheat well with a splash of water or milk, making an easy lunch the next day.
Slow Cooker 3-Ingredient Creamy Chicken PastaServings: 6
Ingredients
1 1/2 pounds boneless, skinless chicken breasts (about 3 medium pieces)
2 jars (15 ounces each) creamy Alfredo sauce
12 ounces dry penne pasta
Directions
Lightly coat the inside of a 5- to 6-quart slow cooker with nonstick spray or a thin film of oil to help prevent sticking.
Place the boneless, skinless chicken breasts in a single layer on the bottom of the slow cooker.
Pour both jars of Alfredo sauce evenly over the chicken, turning the chicken once with a spoon or tongs so it’s well coated in sauce. Make sure the chicken is mostly submerged.
Cover the slow cooker with the lid and cook on LOW for 3 1/2 to 4 hours, or on HIGH for about 2 to 2 1/2 hours, until the chicken is cooked through and easily shreds with a fork.
Once the chicken is tender, use two forks to shred it directly in the slow cooker, stirring to mix the shredded chicken thoroughly into the hot Alfredo sauce. The sauce should look smooth, thick, and glossy.
Add the dry penne pasta straight into the slow cooker, stirring well so all the noodles are coated and submerged in the creamy chicken sauce as much as possible. Scrape down any dry pasta from the sides so it sits in the sauce.
Cover again and cook on HIGH for 20 to 30 minutes, stirring once halfway through, until the pasta is tender but still has a bit of bite. The sauce will thicken further as the pasta releases starch and absorbs some of the liquid.
When the pasta is cooked to your liking, give everything a final stir so the creamy sauce fully coats the penne and shredded chicken. If it seems too thick, you can briefly cover and let it sit 5 minutes; the trapped steam will loosen it slightly while keeping it glossy and creamy.
Serve the creamy chicken pasta hot, spooned onto plates or into shallow bowls. You should see steam rising and a thick, white, glossy sauce clinging to each piece of penne and strand of chicken.
Variations & Tips
Because this recipe is built on just three ingredients, each one does a lot of heavy lifting. Use a good-quality Alfredo sauce you already like the taste of; some are thicker or saltier than others, so you may find you prefer one brand after trying a couple. If you want a looser sauce, stir in a splash of milk, cream, or even a bit of pasta cooking water (if you parboil the pasta first) at the end—but keep in mind that technically adds a fourth ingredient. For a slightly firmer noodle, check the pasta at the 20-minute mark; slow cookers run at different temperatures, and overcooking can make the penne too soft. You can also swap penne for another short pasta like rotini or rigatoni, which hold the creamy sauce well. To stretch the meal or add a bit of color without changing the core three-ingredient concept, serve it over a bed of steamed vegetables instead of stirring them in. If you have leftovers that seem thick the next day, stir in a tablespoon or two of water before reheating to bring the sauce back to a glossy, creamy consistency.
