Creamy slow cooker chicken alfredo with broccoli is a set-it-and-forget-it dinner that turns simple pantry staples into a rich, comforting meal the whole family will love.

There's something magical about coming home to a dinner that has basically cooked itself. This slow cooker chicken alfredo with broccoli is exactly that kind of meal. It's rich, creamy, loaded with tender shredded chicken, and studded with bright, tender broccoli, all swimming in a parmesan alfredo sauce that tastes like it took hours of stirring on the stove. It didn't. Your crockpot did all the work.
If you're searching for yummy slow cooker meals that don't skimp on flavor, this one belongs at the top of your list. It's also one of those rare crockpot meals low calorie enough to feel virtuous, but indulgent enough that nobody at the table will believe it.
Before we get cooking, the right tools and ingredients make a real difference here. A good heavy bottomed slow cooker distributes heat evenly so the cream cheese melts smoothly instead of scorching, and a quality block of parmesan (rather than the shelf stable shaker kind) makes the sauce taste like something from an Italian kitchen instead of a packet.
The secret to a truly great chicken broccoli alfredo pasta crockpot dinner is timing. Chicken breasts can turn stringy and dry if they overcook, and broccoli turns to mush if it goes in too early. This recipe solves both problems by:
Chef's Tip: Don't dump cold cream cheese straight from the fridge into the slow cooker. Let it soften at room temperature for about 20 minutes first, it melts into the sauce far more smoothly and helps you avoid little lumps.
One of the best things about this dish is how easily it adapts. If you're following a lower carb lifestyle, this is one of the most satisfying keto chicken broccoli crockpot recipes you can make, since the sauce itself is naturally low in carbohydrates. Simply skip the fettuccine and spoon the creamy chicken and broccoli straight into a bowl, or serve it over cauliflower rice or zucchini noodles for a low carb chicken alfredo crockpot dinner that still feels indulgent.
If you do want pasta, cook it separately while the slow cooker finishes up, then toss it in right before serving so it doesn't get soggy sitting in the sauce for hours.

Creamy slow cooker chicken alfredo with broccoli is a set-it-and-forget-it dinner that turns simple pantry staples into a rich, comforting meal the whole family will love.
Place the chicken breasts in the bottom of a slow cooker. Add minced garlic, Italian seasoning, onion powder, salt, and black pepper.
Pour the chicken broth over the chicken. Cover and cook on low for 6 hours or high for 3 to 4 hours, until the chicken is tender and cooked through.
Remove the chicken and shred it with two forks on a cutting board, then set aside.
Add the cubed cream cheese to the liquid remaining in the slow cooker. Whisk or stir until it melts into a smooth sauce, about 5 to 10 minutes.
Stir in the heavy cream and grated parmesan cheese until the sauce is silky and well combined.
Return the shredded chicken to the slow cooker along with the broccoli florets. Cover and cook on high for an additional 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 directly into the slow cooker or spoon the chicken broccoli alfredo over individual servings of pasta.
Garnish with extra parmesan cheese and serve warm.
This chicken and broccoli alfredo crockpot recipe is hearty enough to stand on its own, but a few sides round it out beautifully:
Leftovers store beautifully in an airtight container in the fridge for up to 4 days. When you're ready to reheat, do it low and slow on the stovetop with a splash of milk or broth stirred in, since the sauce naturally thickens as it chills. Microwaving works in a pinch too, just heat in short bursts and stir often so the sauce doesn't separate.
Chef's Tip: This dish doesn't freeze well because of the cream cheese and heavy cream base, which can turn grainy once thawed. It's best enjoyed fresh within a few days.
However you serve it, this slow cooker chicken alfredo with broccoli is proof that comfort food doesn't have to mean hours at the stove. Set it, forget it, and let dinner come together on its own.
