There’s something so satisfying about putting a whole roasted chicken on the table, and this keto roasted chicken is no exception! That golden brown skin is irresistible, and because it is brined, the meat is succulent, juicy, and flavored through and through.

What You Need To Make Keto Cajun Chicken

  • A bowl large enough to easily hold the chicken and liquid but still fit in the fridge
  • A roasting pan
  • Butter
  • A big ole whole chicken (about 4-5 pounds) or a similar weight of chicken leg quarters
  • Ingredients for the brine: salt, brown sugar substitute, paprika, oregano, cayenne, garlic powder
  • Ingredients for the dry rub: salt, chili powder, onion powder, cumin, cayenne, thyme, basil, oregano, pepper

How to Make Keto Roasted Cajun Chicken

  1. Mix the salt, brown sugar substitute (I use So Nourished!), paprika, oregano, cayenne and garlic powder in water.
  2. Clean the chicken and submerge it in the brine in a large bowl and refrigerate for about 8 hours or overnight.
  3. Remove the chicken from the brine and pat it dry with paper towels.
  4. Combine the dry rub ingredients and mix it with softened butter, and liberally spread the mixture all over the chicken.
  5. Pop the chicken into a roasting pan and roast until perfect!

Chef Jenn’s Tips for Making Cajun Roasted Chicken

  • Remove the chicken from the brine an hour ahead of baking so it has time to come to room temperature. It’ll cook more evenly this way.
  • Tweak the spices to suit your own preferences! Love the heat? Add a bit more cayenne or smoky chipotle powder.
  • Use the broiler to put a final crispy brown on your chicken for even more flavor!

What To Serve With This Keto Cajun Recipe

There’s sooo much flavor in this keto chicken dish so you want sides that don’t try to steal its thunder. Opt for easy picks like Mashed Turnips or a simple side salad topped with this amazing Ranch Dressing.

Is This Cajun Chicken Recipe Freezer Friendly?

Yes, you can freeze it, but be warned, the chicken skin won’t be crispy after thawing.

To freeze this dish, cool the chicken down completely and then freeze it for up to three months.

To eat, let it thaw and then enjoy it cold on a salad or warm it covered (so it doesn’t dry out) in the oven at 325-F. You can crisp the skin again under the broiler.

How do I make Cajun seasoning?

Cajun seasoning is a blend of spices and a wee bit of sugar! Everyone has their own recipe, but I like a blend of brown sugar, paprika, cayenne (for a bit of heat), thyme, onion powder, chili powder, and oregano, along with salt and pepper of course.

How do I roast chicken?

Chicken can be roasted two ways – either low and slow in an oven or start out at a higher temperature and then drop the heat and cook it low and slow. I like both methods.

What does Cajun seasoning taste like?

Cajun seasoning is a herby blend with a touch of sweetness and smokiness. It is a lovely flavor combination and is hugely versatile.
