Ranch Chicken Stuffed Shells

My love for pasta runs deep. You all know that I have a soft spot in my heart for all of the carbs, but especially stuffed shells. My Lasagna Stuffed Shells are made on the regular here in the One Sweet Appetite home but this chicken ranch version may slide into our #1 spot.

It has EVERYTHING. Cooked chicken is shredded and tossed with cheddar cheese, spinach, green onion and stuffed into cooked pasta shells. A homemade ranch Alfredo is poured over the top and everything is sprinkled with bacon pieces. The only way I can even begin to describe it?

SO GOOD. Like, get in my belly right this second delicious. I could eat the sauce on anything and everything. Pin this recipe, print it out, and add it to your must-make list!

How to make a ranch Alfredo sauce:

It is no surprise that the star of the show is the Alfredo. Cream, rich, and a slight ranch flavor. It kicks this pasta dish up a notch and makes it drool worthy. Let’s dive into the secret of how to make Alfredo sauce.

  1. Start by gathering all of the ingredients. The key components are butter, flour, milk, and cheese. Stick with Parmesan if you want that classic Alfredo flavor.
  2. Melt butter in a medium saucepan. Whisk in equal amounts of flour. Cook 1-2 minutes or until bubbly. Make sure you whisk it consistently.
  3. Slowly stir in the milk. Simmer 1-2 minutes or until it is just slightly thickened. Make sure you keep whisking to keep it from burning on the bottom.
  4. Remove the sauce from the heat. Stir in the Parmesan cheese and ranch dressing mix.
  5. Serve with your favorite pasta!

Do NOT skip the bacon. I know, I know. I technically said it is optional. But guys… Bacon makes everything SO delicious!

I made these last night, they were time consuming to make but 110% worth the effort. I used bacon grease vs butter, I also used heavy whipping cream vs whole milk. It made the sauce thicker but I thinned it out with 2% before baking. I would add more bacon- DON'T SKIP THE BACON! Family loved it!

Hi Abbie. This recipe can be a tad time consuming, I agree. But it is well worth it. I will have to try it with cream!


Monday 7th of December 2020

We don’t ever use whole milk at my house. Do you think the sauce would be fine using 2%?


Monday 7th of December 2020

You can use 2%. It just won't be quite as creamy, but it's not a huge difference. I wouldn't use anything under 2%.


Sunday 29th of November 2020

For a lot of recipes using frozen spinach, you are supposed to squeeze as much water out of it as this a necessary step for this recipe??


Monday 30th of November 2020

Yes. Thanks for catching that. I will add that into the recipe instructions.

Any "make ahead" tips? I wondered if I could prep & fill the shells the night before & then make the sauce & bake just before serving.


Tuesday 6th of October 2020

We've done this before! I just suggest waiting until the day of to make the sauce. When it sits in the fridge it tends to thicken and doesn't give you that thinner (seriously looking for a better word) consistency you need. We have even made the entire thing the day before and tossed it in the oven. It is just a smidge dryer than I like when we do it this way, but gets rave reviews from my husband and kid.
