Slow And Low Does The Trick

While the Instant Pot is a convenient tool (and we provide Instant Pot instructions for this recipe in the notes below), there is something comforting about using the slow cooker. I love being able to throw a big beef roast in the slow cooker and let it cook all day. The slow cooker not only breaks down the roast into tender and fall apart pieces, it also fills your house with the delicious smells of BBQ beef. Can anyone else smell it right now?

An Easy Whole30 BBQ Sauce

I’ve tried a few variations of homemade BBQ sauce, and I think this one is the best yet! It has just a hint of sweetness from the coconut aminos and some savory and tangy notes from smoked paprika, mustard and vinegar. The best part is, making the sauce for this slow cooker BBQ beef is so simple and easy. Just whisk the ingredients together in a jar or bowl, no blending or processing required!

Slow Cooker BBQ Beef (Paleo + Whole30)

This Paleo and Whole30 slow cooker BBQ beef is easy to prep and oh so delicious thanks to a tangy and tantalising Whole30 compliant BBQ sauce! Serve it with anything and it’s a perfect freezer meal for meal prep. 


  • 4 lb chuck roast
  • 2 tbsp ghee, (or coconut oil for dairy free)
  • 1 onion, diced
  • Sea salt and pepper

For the sauce:

  • 1 cup coconut aminos
  • 1/2 cup tomato paste
  • 1/4 cup white vinegar
  • 2 tbsp mustard
  • 1 tbsp garlic powder
  • 1 tbsp onion powder
  • 1 tbsp chili powder
  • 1 tbsp smoked paprika


  • Cut roast into 4 pieces and season each piece lightly with salt and pepper. Chop onion as noted and place it in the slow cooker
  • To make the BBQ sauce, place all of the sauce ingredients in a mixing bowl and whisk well to incorporate. Place 1/2 of the sauce in a container and refrigerate, you'll use after the beef is cooked. 
  • Heat a large skillet over medium heat and add ghee. Once hot, add the roast pieces and sear on both the main sides for 4-5 minutes. After the main 2 sides are seared, turn the roast and quickly sear the other 4 sides for 1 minute each. Depending on the shape of the roast some ends might be hard to sear. Just do the best you can to sear all sides. 
  • Place the beef on top of the onions in the slow cooker. Pour the remaining half of the BBQ sauce over everything.
  • Place the lid on the slow cooker and cook on low for 8-10 hours. 
  • When the beef is finished, shred it with 2 forks (either transfer to a cutting board or do it in the slow cooker). Mix it in well with the onions and juices/sauce from the slow cooker. Serve topped with additional BBQ sauce as desired.

To make this in an Instant Pot, cut the roast into smaller pieces, about 2×2 inch cubes. Sear for 2-3 minutes on each side (either in the instant pot or skillet). Add in the onions and sauce and toss to coat.
Secure the lid on the instant pot and close the pressure valve. Press the “manual” button (or “pressure cook” button) and set the time to cook for 30 minutes at high pressure. Once the time is up, let the pressure naturally release on its own for 20 minutes. Manually release any remaining pressure and remove the lid. Shred the beef with two forks.
