Creamy slow cooker chicken alfredo with tender broccoli is the ultimate hands off weeknight dinner, packed with rich parmesan sauce and juicy chicken in every bite.

There is something magical about walking into a kitchen that smells like garlic, parmesan, and slow simmered cream sauce after a long day. This slow cooker chicken alfredo with broccoli is exactly the kind of yummy slow cooker meal that makes weeknights feel effortless. You dump everything into the crockpot, walk away, and come back to a rich, restaurant quality dinner that the whole family will fight over.
This recipe has become one of my go to crockpot meals low calorie enough to feel good about, yet indulgent enough that nobody at the table will guess how easy it was. Juicy shredded chicken, a velvety parmesan cream sauce, and tender broccoli come together in one pot with almost no cleanup.
Before we get cooking, the right tools and ingredients make a real difference here. A good quality slow cooker with even heat distribution keeps the chicken from drying out, and freshly grated parmesan melts far more smoothly into the sauce than the pre shredded bagged kind. These are the products that genuinely help this recipe shine:
Unlike stovetop alfredo, which can break or turn grainy if you look away for two minutes, the slow cooker method is nearly foolproof. The chicken gently poaches in broth and garlic until it's fall apart tender, and the cream cheese and parmesan melt into a glossy sauce with almost no babysitting required.
This is also one of the easiest keto chicken alfredo crockpot recipes you'll find, since swapping the pasta for cauliflower rice or zucchini noodles turns it into a genuinely low carb chicken alfredo crockpot dinner without sacrificing flavor.
Chef's Tip: Add the broccoli in the last 20 to 30 minutes only. Tossing it in too early turns it olive drab and mushy, while a short final simmer keeps it bright green and just tender.
A few small details make a big difference in this chicken and broccoli alfredo crockpot recipe.
If you like a thicker sauce, let it sit uncovered on the warm setting for 10 minutes before serving. It will continue to thicken slightly as it cools.
Ready to make it? Here is the full step-by-step recipe:

Creamy slow cooker chicken alfredo with tender broccoli is the ultimate hands off weeknight dinner, packed with rich parmesan sauce and juicy chicken in every bite.
Place the chicken breasts in the bottom of a 6 quart slow cooker.
Add the minced garlic, chicken broth, Italian seasoning, salt, and black pepper over the chicken.
Cover and cook on low for 6 hours or on high for 3 to 4 hours, until the chicken is cooked through and shreds easily.
Remove the chicken to a cutting board and shred it with two forks, then set aside.
Add the cream cheese cubes to the slow cooker and whisk until melted and smooth, about 5 minutes.
Stir in the heavy cream and grated parmesan cheese until the sauce is silky and combined.
Return the shredded chicken to the slow cooker and stir to coat in the sauce.
Add the broccoli florets, cover, and cook on high for 20 to 30 minutes, until the broccoli is tender but still bright green.
Taste the sauce and adjust salt and pepper as needed.
If serving over pasta, toss the cooked fettuccine with the chicken alfredo mixture directly in the slow cooker.
Garnish with extra parmesan and chopped parsley before serving.
This dish is wonderfully flexible. Serve it the classic way over fettuccine for a comforting chicken broccoli alfredo pasta crockpot dinner, or keep things lighter and lower carb by spooning it over rice, mashed cauliflower, or roasted spaghetti squash.
For extra flavor, try stirring in a pinch of red pepper flakes or a squeeze of lemon juice right before serving to brighten the richness of the sauce. Leftover sauce also makes a fantastic base for a next day baked pasta casserole, just toss it with pasta, top with extra mozzarella, and broil until bubbly.
Leftovers keep beautifully in the fridge for up to 4 days in an airtight container. Since cream sauces naturally thicken as they cool, reheat gently over low heat on the stovetop or in the microwave in short bursts, stirring in a splash of chicken broth or milk to bring the sauce back to its original silky consistency.
This crockpot chicken broccoli alfredo has quickly become one of my favorite yummy slow cooker meals for busy weeks, and I have a feeling it's about to become one of yours too. Once you taste how creamy and comforting it is straight from the slow cooker, you'll understand why it belongs in your regular dinner rotation.
