BBQ Chicken Mac and Cheese Ingredients
You’ll only need 5 things to make this recipe:
- pulled bbq chicken
- pasta shells
- milk
- shredded cheese
- salt, pepper, and optional seasoning
Below, you’ll find details on everything we used and how to make substitutions to make this bbq chicken mac and cheese your own.
The Pulled BBQ Chicken

As you’ll see in the recipe card at the bottom of the post, I used my slow cooker bbq chicken recipe. My Instant Pot bbq chicken, Dutch oven shredded chicken, and smoked chicken thighs are also great options.
Both recipes work with boneless skinless chicken thighs or chicken breast and are perfect for preparing in bulk to use in recipes like this mac and cheese, bbq chicken sliders, or loaded bbq chicken nachos.
If you don’t want to take the time to prep your own chicken, you could use some shredded rotisserie chicken mixed with your favorite bbq sauce. You’ll need a pound of cooked chicken for this recipe, so I’ll leave it up to you to decide how much sauce you want for that amount of chicken.
For red meat lovers, check out my pressure cooker pulled pork or slow cooker beef shoulder roast recipes.
The Pasta and Cheese Sauce

For the pasta, we used Banza chickpea pasta shells like in our breakfast mac and cheese. Though any pasta will get the job done here. Just be sure to save some of the water after cooking the pasta. You want the starch in the pasta water for making a smooth cheese sauce that sticks to the pasta.
You should be able to use any milk, but using real milk with a little fat (say 2% or whole) will work best. And for the cheese, we used a blend of cheddar, Monterey jack, and mozzarella. For best results, shred your cheese fresh off the block instead of buying pre-shredded.
Assembling the BBQ Chicken Mac and Cheese

Once you have your bbq chicken and mac ‘n’ cheese sorted, it’s time to assemble. We used a 13×8 baking dish, but an oven safe skillet would work fine as well.

You can either mix everything together in the original pot or in the baking dish, it doesn’t really matter!

One note you’ll see in the recipe card is about reducing the cheese on top (and in the sauce) to reduce the fat and calorie content. You can get an idea of what 2 oz of shredded cheese looks like in the photo above. It’s a good amount of coverage, but you could get by without it.
If you wanted to reduce, or even omit altogether, I would still pop your bbq chicken mac and cheese in the oven to thicken the cheese sauce, warm any bbq sauce drizzle, and get some crispy bits on the chicken.
Another topping option might be a crispy breadcrumb topping like from our green chile chicken mac and cheese or ultimate protein mac n cheese recipes.
Side note: You could also make this recipe entirely in the Ninja Foodi or Instant Pot Duo Crisp. Check out my Ninja Foodi mac and cheese for an example. You’d just stir in the bbq chicken, top with cheese, and broil for 8-10 minutes.

Okay, that should cover it. In case you’re in need of some veggie sides, check out my air fryer brussels sprouts, air fried green beans, or balsamic roasted carrots. Or this post on the best sides to serve with mac and cheese.

BBQ Chicken Mac and Cheese
Ingredients
- 16 oz Pulled BBQ Chicken*
- 8 oz Banza Pasta Shells
- 1 C Pasta Water
- 1 C Milk
- 10 oz Shredded Cheese Blend, divided
Instructions
- Preheat an oven to 400ºF and bring a pot of salted water to a boil for the pasta.
- Cook the pasta for 8-9 minutes until tender. Reserve 1 cup of pasta water before draining the pasta. Set aside.
- Set the burner to its lowest setting and add the drained pasta back to the pot with the cup of pasta water and milk. Stir to fully incorporate.
- Gradually fold in 8 oz of shredded cheese 1-2 oz at a time until you have a smooth sauce. (Don’t worry if the sauce is slightly runny, it will thicken in the oven once the chicken is added.) Salt and pepper to taste.
- Transfer the mac and cheese to a baking dish or oven safe skillet and stir in the pulled chicken. Top with 2 oz of shredded cheese and drizzle with BBQ sauce (optional). Bake for 8-10 minutes until the cheese is melted and bubbly.
Notes
Nutrition Facts Notes
- Each serving has 10 WW SmartPoints (blue).
- To reduce the fat/calorie content, you can reduce the milk to 1/2 C and cheese to 4-6 oz in the pasta. You can also top with 1 oz instead of 2 oz. And the slow cooker chicken we used is with chicken thighs. Using chicken breast will reduce the fat/calories as well.





We made this Sunday and it was so delicious! I had my nieces over who have bad memories of aunties past cooking so they were clearly skeptical! However, it was a hit! We also used banza pasta, a rotisserie chicken from Costco (they’re so big they make 2 suppers easily) and FRESH CHEESE! It’s seriously the KEY! We buy ours from a local farmer and it’s amazing. You don’t get that stringy Mac and cheese mess. Ya’ll will love this! Update bc this didn’t even post (I think)- shredding that much cheese isn’t for the faint of heart. I wish I had one of those block graters that stand.
I followed the recipe exactly and it came out perfect. I added some hot pepper flakes after. I love how the recipes have the ingredients with grams because I do weigh everything.
Yes yes and more yes. This recipe HIT THE SPOT! So good and you’d never know it was near effortless! I used some leftover chicken I had and it was *chef’s kiss* delicious!
Tastes like you’re indulging but the ingredients allowed me to easy fit this recipe into my macros for the day! We made with unsweetened almond milk, but next time will definitely use real milk with a little fat like suggested in the recipe – I think that will up the richness and cheesy-ness!
Delicious! We make this during these shoulder season months in the DC area. Kinda hot during the day, but rainy and windy cold during the evening. It’s the perfect meal to get a good amount of protein, but feel like you’re “cheating” a bit.
We made this casserole tonight and it was really good – although I think next time I’ll use full fat milk 😉 and cheese. I count my macros and used low fat cheese & oat milk. It was still really yummy but the consistency was off. We also used a mustard based bbq sauce and loved the flavor!
Mac n cheese is my favorite meal ever so I am
Always nervous about making a lower macros option. This did not let me down and every bite was delicious!
Very easy to follow for amazing results! My fiancé and I cook this minimum once a week and it is hard to save any leftovers! So much flavor for such good macros!
Honestly I’m dairy free but I bit the bullet just so I could have this (yes I know I could’ve made substitutions but it’s never the same) & guys IT WAS SO GOOD!!
Highly recommend adding smoked cheddar for even more flavor!! 10/10
Nice touch with the smoked cheddar. And we’ll still be awaiting your dairy free version in the Facebook group!
Honestly this was worth making with full dairy. I’m typically a substituter in most recipes but I just wanted to go for it in this one and let’s be real it was worth it! Use smoked cheddar!! So good!!!
