PIN Cajun burger with sweet potato bun

After 4 years of blogging, in the eyes of Mr. FFF I finally reached the "VIP champion of kitchen status".

As I told you in the Cajun Cauliflower Casserole and the Cajun Cauliflower Tater Tots Casserole, Mr. FFF is obsessed with Cajun food and ALWAYS asks me to prepare recipes with a Cajun flavor.

When I do that, I make them from ALL vegetables and it doesn't make him so happy, except that I made it Cajun Instant Pot Chili once.

I don't think he imagined cauliflower when he suggested these things to me.

BUT, since he graduated – and lived – from the nurse anesthetist school, I've decided to surprise him with CAJUN + BEEF.AKA: The tune to which his fun-loving Cajun food-addicted heart beats.

I mean, let's ignore the fact that all I had to do was sneak in vegetables in the form of a SWEET POTATO BUNNO (!!!), but can we be mad at it? I mean they're still carbohydrates AND they're about eleven billion times more delicious AND nutritious than a bun. At least this time I made him a "bun" and didn't serve him a burger in a bowl, did I?

No bun? No problem!

I love a good burger. In spring and summer I only want to grill with Mr. FFF and burgers are always a place to go! I am such a fan of all types of burgers and I am also all for creativity to keep my burger game strong! Therefore, I will introduce you to a new type of bun: my sweet potato bun recipe! If you didn't know, sweet potatoes are my jam – whether I cook something Mexican sweet potatoes baked twice or Incorporate into a delicious dessert like Gluten-free sweet potato cake barsI always have them on hand. You won't even miss the bun on these burgers because the sweet potato buns are absolutely delicious.

How to make sweet potato buns from scratch

It's not as difficult to prepare these delicious and unique buns for your burgers as you might think! Sweet potatoes bring the taste and texture of their own accord, with a little help from some olive oil and salt! How it works:


Use a sharp knife to cut 8 slices from the center of your sweet potato. It is the thickest part, the largest and the best Sweet potato bun.


Place your sweet potato slices in a large, microwave-safe bowl and add a splash of water to the bowl. Microwave until the sweet potatoes soften, which should take about 2 minutes. After heating, drain the water and pat each slice dry with a paper towel.


Brush each side of the sweet potato slices and grill until you get nice marks. This should take about 4 minutes. Turn over and cook for another 3-4 minutes or until cooked and soft but not mushy.


Top each sweet potato bun with ketchup, vegetables and a burger and finish with the rest of the sweet potato bun. Devour!

  • 2nd TL Extra virgin olive oil
  • 1/2 Big green pepper, cut thin
  • 1/4 Big onion, cut thin
  • 1/2 Cup Celery, cut thin
  • 1/2 tablespoon Fresh garlic, chopped


  • Preheat your grill to high heat and let it heat up for at least 10 minutes.

  • Heat the olive oil (for the vegetables) in a large pan over medium heat. Add pepper, onion, celery and garlic and cook for 5-7 minutes, stirring frequently, until they are soft and golden brown. Keep warm on low heat.

  • Mix ground beef, cajun spice and salt in a large bowl and mix evenly. Shape into 3 3/4 inch patties. Lightly brush each side with olive oil.

  • Make 8 slices from the center of the sweet potato (it's the largest part) about 1/4 inch thick. Place them in a large, microwave-safe bowl and add a little water. Cover and microwave until they just start to soften, just about 2 minutes. Drain the water and pat the potatoes dry with a paper towel. * *

  • Brush the oil on each side of the potatoes and grill for approx. 4 minutes until nice signs are formed. Turn over and cook and another 3-4 minutes until the fork is soft but not mushy.

  • While the potatoes are cooking, mix all of the ketchup ingredients in a medium bowl.


  • Spread the ketchup over all 8 sweet potato slices. Divide the vegetables into 4 slices and place a burger on each slice covered with vegetables. Cover with the remaining sweet potatoes.

  • Devour!
