- It’s hands-off comfort food. The slow cooker handles the work while you handle… life.
- Creamy, garlicky, cheesy goodness. It’s basically a warm hug in pasta form.
- Family-friendly. Picky eater? This is one of those “they’ll eat it and ask for seconds” meals.
- Minimal dishes. And honestly, that might be the most beautiful part.
Ingredients You’ll Need
Here’s what goes into your slow cooker to create that rich, creamy magic:
- 1 1/2 pounds boneless, skinless chicken breasts
- 12 ounces medium pasta shells (uncooked, about 3 cups dry)
- 2 cups low-sodium chicken broth
- 1 1/2 cups heavy cream
- 1 cup freshly grated Parmesan cheese, plus more for serving
- 1/4 cup roasted garlic cloves or paste (about 1 small head, mashed)
- 1 teaspoon dried Italian herb blend
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1 teaspoon kosher salt (plus more to taste)
- 1/2 teaspoon freshly ground black pepper
- 2 tablespoons unsalted butter, cut into small pieces
- 2 tablespoons chopped fresh parsley (optional, for garnish)
Little chef note from Mounia: Freshly grated Parmesan melts better and tastes smoother than the pre-shredded kind. Pre-shredded still works if that’s what you’ve got—no pasta police here.
How to Make Slow Cooker Creamy Garlic Parmesan Chicken Shells
1) Prep the slow cooker
Lightly spray the inside of a 6-quart slow cooker with nonstick spray. Future-you will be grateful during cleanup.
2) Add the pasta shells
Scatter the uncooked shells evenly across the bottom. Try for one layer-ish. (It doesn’t have to be perfect—this isn’t a geometry exam.)
3) Place the chicken on top
Lay the raw chicken breasts right on top of the pasta shells. Nestle them down slightly so everything sits in a fairly even layer.
4) Mix the creamy garlic-Parmesan sauce
In a medium bowl (or big measuring cup), whisk together:
- chicken broth
- heavy cream
- Parmesan
- roasted garlic
- Italian herb blend
- garlic powder
- onion powder
- salt and pepper
Whisk until mostly smooth. If the Parmesan makes it a little lumpy, that’s normal—cheese does what it wants.
5) Pour and butter-dot
Pour the sauce evenly over the chicken and pasta. Try to cover the shells as much as you can. Then dot the top with the butter pieces.
6) Slow cook
Cover and cook:
- LOW for 3 1/2 to 4 1/2 hours, or
- HIGH for 2 to 2 1/2 hours
You’re looking for chicken that’s cooked through (165°F) and shells that are tender but not mushy.
Important tip: Try not to lift the lid in the first couple hours. Every peek lets out heat and steam—and pasta is a little dramatic about that.
7) Shred the chicken
Move chicken to a cutting board, shred with two forks, then return it to the slow cooker.
8) Stir and finish
Stir everything well so the shells are coated and the chicken is evenly mixed in. Taste and adjust salt/pepper.
If the sauce feels too thick, splash in 1–2 tablespoons warm broth or cream and stir again.
9) Rest, garnish, serve
Let it sit on WARM for 5–10 minutes to thicken a bit. Top with extra Parmesan and parsley, then serve!
Tips for the Creamiest, Dreamiest Results
- Use roasted garlic for that mellow flavor. It’s rich, sweet, and totally different than sharp raw garlic.
- Don’t overcook the pasta. If your slow cooker runs hot, start checking closer to the early end of the time range.
- Grate your Parmesan fresh if you can. It melts into the sauce better and gives you that restaurant-style creaminess.
- Sauce too thick? Don’t worry—it’s just extra comfort waiting to happen. Add a splash of warm broth or cream and stir.

FAQs About Slow Cooker Creamy Garlic Parmesan Chicken Shells
Can I use chicken thighs instead of chicken breasts?
Absolutely. Boneless, skinless thighs work great and stay extra juicy. Cooking time is similar, but still aim for 165°F.
Can I make this with a lighter cream?
Heavy cream gives the best creamy texture. You can use half-and-half, but the sauce may be thinner. If you do, let it sit on WARM a little longer at the end to thicken.
What if I don’t have roasted garlic?
You can substitute with 2–3 teaspoons garlic paste or 3–4 minced garlic cloves, but roasted garlic is milder and more “cozy.” If using raw garlic, start smaller—you can always add more.
How do I store leftovers?
Store in an airtight container in the fridge for 3–4 days. The sauce thickens as it chills.
How do I reheat it without drying it out?
Reheat gently on the stove or microwave with a splash of broth, cream, or milk. Stir halfway through and you’ll bring that creamy sauce right back to life.
