BBQ Crockpot Pork Tenderloin with Low Calorie Mac and Cheese

I’ve made lots of low calorie mac and cheese recipes because, well, duh. But smothering juicy, tender bbq crockpot pork tenderloin in mac and cheese and baking with a layer of melted cheddar on top really takes things to another level. 

At first glance, this recipe may look a bit longer than my typical fare. An impasta, if you will.

Have no fear, though, it’s really two recipes in one. They’re both super simple on their own and customizable as always.

Ingredients for BBQ Crockpot Pork Tenderloin

If I had to describe this BBQ sauce, it would be my Carolina BBQ Crockpot Shredded Chicken recipe combined with a bit of Memphis-style BBQ flavor. There’s added sweetness and the tomato-based sauce you’d expect.

Here’s a look at what you’ll need aside from two pounds of pork tenderloin:

  • reduced sugar ketchup
  • yellow mustard
  • apple cider vinegar
  • worcestershire sauce
  • peeled garlic

And a handful of dry ingredients:

  • Swerve Brown (or light brown sugar – you could also skip this ingredient) 
  • salt, pepper, paprika, and crushed red pepper (also optional)

The BBQ pork tenderloin itself is crazy simple. Just mix everything together and throw in a slow cooker for about two hours. Then pull, shred, or chop (my choice for this recipe) and add it to some mac and cheese. You’ll be flyin’ high! 

Ingredients for Low Calorie Mac and Cheese

I mentioned that I’ve made tons of mac and cheese recipes, but I’m 95% positive this is the best one to date. Here’s what you’ll need: 

  • Banza elbows (or your choice of higher protein pasta)
  • fat free cream cheese
  • fat free Greek yogurt
  • shredded mozzarella
  • light butter

And to make it extra cheesy:

  • cheddar powder (optional)
  • shredded cheddar (if you’re making a mac and cheese bake)

What is cheddar powder? 

Cheddar powder is essentially dehydrated cheddar cheese that can be reconstituted to make cheese sauces like you see with the cheese dipping sauce or used as a dry seasoning on popcorn or fries (like my nacho fries).

Since there are technically two recipes here, you may want to mix and match. I’ve included the nutrition facts for both individual recipes in the recipe card below.

Final Recipe Notes

I think that’s about it! Keep in mind, the crockpot pork tenderloin is difficult to mess up. Feel free to tweak the sauce ingredients and as long as you don’t overcook it, you’ll be fine.

The mac and cheese might be a little more difficult to tweak but if you’re looking for other options, I’ll link a few additional recipes below the recipe card.

  • Super easy recipe that combines two of my favorite things! I used G. Hughes Sugar Free BBQ sauce (for convenience) and paired the bake with your protein coleslaw for some crunch. Will most definitely be making this again!

  • We subbed the meat for some pulled pork we had frozen from the smoker, worked out perfect. This recipe was spot on. I was super nervous about the cheeses but loved the combination!! Can’t wait to try more.

  • Doubled the pork recipe and we ate the pork on top of spicy tomato rice cake chips by the pool. It was an insanely fun and guilt free snack.

    We prepped the mac n cheese for the week and skipped the oven step. Gave it the final cook on a serving at dinner in the air fryer on some foil for 15 min or so. Doesn’t get any better than this.

  • I subbed for pulled bbq pork! Not sure how this is low calorie but I’m not mad! I had brought this for lunch one day at work, they had catered in and I felt bad for everyone else knowing my food tasted 10000X better.

  • I think this is my #1 all time favorite Mason recipe. The mac and cheese pairs amazingly with the BBQ pork. I did cook the pork in the Instant Pot rather than the crockpot. I ate this everyday for lunch throughout the week and it reheated really well. My husband is not a “leftover” eater but he ate this with me for a few days too. For the cheddar powder I use King Arthurs Vermont White Cheddar.

  • Loved the combination of BBQ chicken with mac and cheese and never would have thought to do it! The mac and cheese is so good by itself if you’re looking for a side dish option just make that without the BBQ chicken. I would probably use a different BBQ chicken recipe with this in the future because the BBQ chicken in this recipe was sweeter than I prefer.

  • This recipe was great! I added garlic and onion powder and more black pepper and cayenne pepper to the cheese sauce but it’s definitely a hit!

  • I have never made the BBQ with this recipe, just the mac & cheese. The mac & cheese is so good! My daughter wants me to make it all the time and she tells me it taste like Chick-Fil-A’s Mac & Cheese!!!
