Easy Slow Cooker Olive Garden Chicken Alfredo Pasta (Copycat Recipe)

I love a recipe that creates a restaurant-quality meal right at home; where I can simply set it and forget it and make enough to feed my entire family. That’s why this copycat version of Olive Garden’s signature chicken alfredo is proof that the easiest recipes can be the best ones.

The chicken is so juicy and tender from simmering in the slow cooker and our homemade alfredo sauce is creamy and savory. And when the flavorful rich sauce and penne are combined with the zesty shredded chicken, it makes a family favorite meal for a fraction of the price of a plate of this restaurant’s famous pasta. 

While Chicken Alfredo may be the most popular dish at Olive Garden, mostly because of its cheesy sauce, it’s no wonder that the homemade version has taken over the internet and gone viral on TikTok. Not only is my homemade Alfredo deliciously flavorful, with just the right amount of garlic and Parmesan, but I also know that it contains no artificial ingredients, so I know exactly what I am feeding my family.

Easy-to-make comfort food can be so much more than an imitation pasta meal smothered with a substitute-of-a-sauce!

How to Make the Slow Cooker Olive Garden Chicken Alfredo Pasta

This Slow Cooker copycat version of Olive Garden’s Chicken Alfredo Pasta tastes just as rich and delicious as the original restaurant recipe, but can easily be made at home. It takes only 15 minutes of prep and the crock pot will do the rest of the work.

  1. Add chicken to your slow cooker and sprinkle with salt, pepper, and Italian dressing mix. Pour chicken broth into the slow cooker, cover, and let it cook for 4 hours.
  2. Remove cooked chicken and shred it on a cutting board using 2 forks. Discard all but 1 cup of remaining liquid from the slow cooker. Place shredded chicken back in the slow cooker and add the seasoned cooking liquid. Turn your crockpot to WARM while you cook your pasta and make your sauce.
  3. Melt butter in a saucepan and whisk in the flour. Add garlic, dried parsley, salt, and black pepper to the saucepan and whisk with the butter and flour.
  4. Slowly add the half & half and heavy cream. Cook your cream mixture until it starts to bubble and thicken, whisking often.
    Pro Tip: It is very important to whisk the entire time to avoid any lumps in your final Alfredo sauce.
  5. Once cream mixture has thickened, turn off the heat and stir in parmesan cheese.
    Pro Tip: To help make your sauce extra creamy, allow your cheese to come to room temperature before adding it to the sauce.
  6. Add cooked and drained pasta to the shredded chicken. Pour Alfredo sauce over pasta and chicken and stir to combine.
    Pro Tip: Alfredo sauce thickens while standing and thickens even more when added to the cooked pasta. If it seems too thin, resist the urge to thicken it as it will thicken once mixed with your pasta.
  7. Top with chopped parsley if desired. Serve and enjoy!
    Pro Tip: You can keep your crock pot on warm for 30 minutes before the pasta gets too soft and absorbs excess moisture.

Tips From Our Recipe Developer

  • I love using crock pot liners because they make clean-up so easy!
  • If you want to make this a very easy meal, you can substitute the homemade sauce for a good quality jarred alfredo sauce. I would recommend at least 2 (24-36-ounce) jars for this amount of pasta and chicken.
  • If you prefer dark meat, you can use 2 pounds of skinless boneless chicken thighs in place of the boneless skinless chicken breasts. It will be equally as easy and delicious. 
  • You can use any short, sturdy pasta for this dish. I do not recommend elbow noodles or spaghetti noodles because they are not sturdy enough to hold up to this rich and creamy sauce.

Storage Tips

  • To Store: You can store any leftovers in a covered container in the refrigerator for up to 3 days. 
  • To Freeze: I do not recommend freezing this dish since pasta and dairy does not thaw well.
  • To Reheat: Reheat any leftovers in the microwave or stovetop. You can add a splash of water if it’s too thick.

Frequently Asked Questions

What should I serve with my Olive Garden Chicken Alfredo and Pasta?

This is a hearty, filling meal, so I like to serve this with a simple side salad. I think a green salad balances the cream sauce perfectly. You can also serve this with roasted or steamed veggies for an easy and light side dish. You may also want to serve some garlic bread or a nice loaf of bread to soak up the extra sauce!

Can I make this Chicken Alfredo without pasta?

If you prefer to have just the chicken and sauce without the pasta, you can absolutely leave the pasta out.

Can I cook my pasta in the slow cooker?

I’ve tried several slow cooker recipes with pasta and have never been satisfied with the texture. It just turns into a mushy mess. The secret to successful pasta in the slow cooker is to add the pasta at the end. It just doesn’t need to simmer for hours.

What size slow cooker should I use?

I recommend using a 6-quart slow cooker or larger.

Can Alfredo sauce be made ahead of time?

Alfredo sauce is a great make-ahead and freezable sauce to have on hand to make weeknight meals even easier. The sauce can be stored in the fridge for 3-4 days. It can be frozen in an airtight sealed freezer container and used within 6-8 weeks. Frozen Alfredo sauce should be thawed overnight in your fridge before adding it to the chicken and pasta.

This Slow Cooker copycat version of Olive Garden’s Chicken Alfredo Pasta tastes just as creamy, rich, and delicious as the original restaurant recipe, but can easily be made at home. It takes only 15 minutes of prep and the crock pot will do the rest of the work!
Prep Time 15 minutes
Cook Time 4 hours 15 minutes
Total Time 4 hours 30 minutes

Ingredients
  

  • 2 pounds (3-4 pieces) boneless skinless chicken breasts
  • 16 ounce box penne pasta
  • 1 cup low-sodium chicken broth
  • 0.7 ounce packet dry Italian dressing mix
  • 1 tsp kosher salt divided
  • ½ tsp black pepper divided

  • cups grated parmesan cheese
  • ½ cup all-purpose flour
  • 10 tbsp unsalted butter

Instructions
 

  • In the insert of your slow cooker/crockpot, place your boneless skinless chicken breasts. Sprinkle ½ teaspoon kosher salt and ¼ black pepper evenly over the chicken. Sprinkle the entire contents of the dry italian dressing mix evenly over the chicken as well.
  • Pour the chicken broth into the crockpot with the chicken and spices. Cover with the lid and turn on HIGH for 4 hours.
  • Once your chicken is done, remove it and shred it using 2 forks to pull it apart into bite-sized pieces.
  • Pour out all but 1 cup of the excess liquid that is remaining in the pot. Return the shredded chicken back to the crockpot insert and add back the reserved 1 cup of the seasoned cooking liquid.
  • Turn your crockpot to WARM while you cook your pasta and make your sauce.
  • Cook your pasta according to package directions (8-10 minutes) and drain when done.
  • In a medium saucepan, on medium heat, melt your butter. Once your butter is melted, whisk in the flour making sure there are no lumps.
  • Add your grated garlic, dried parsley, remaining ½ teaspoon salt, and ¼ teaspoon black pepper. Whisk to combine. Slowly add the half & half and heavy cream, making sure that you are whisking the entire time. This is very important to avoid any lumps in your final alfredo sauce.
  • Cook your cream mixture for 5-6 minutes, whisking often, until it starts to bubble and thicken. Once your cream mixture has thickened, turn off the heat and add your grated parmesan cheese. Stir to completely combine.
  • Add your cooked and drained pasta to your shredded chicken, then pour your alfredo sauce on top. Stir to combine. You can top your slow cooker Olive Garden chicken alfredo pasta with the fresh chopped parsley at this time if desired.

    Made this tonight… my boys loved it! I needed to make a second box of pasta, it was too saucy for only one box. (Would of been better with a box and a half!).
