These No-Bun Cajun Burgers use grilled sweet potato buns instead of bread! They’re a healthy, whole30, gluten-free and dairy-free summer meal with a taste of the South!
I told you in the Cajun Cauliflower Casserole and Cajun Cauliflower Tater Tots Casserole, my husband is OBSESSED with Cajun food, and he ALWAYS asks me to make Cajun flavored recipes.
Then, when I do, I make them out of ALL of the vegetables and it makes him not so happy, except that one time I made him Cajun Instant Pot Chili.
I guess he wasn’t picturing cauliflower when he suggests these things to me.
I recently decided to surprise him with Cajun + beef.
I just had to sneak vegetables in there, In the form of a SWEET POTATO bun but can we be mad at that? While they’re still carbs AND they’re about eleventy billion times more delicious AND nutritious than a bun. At least I made him a “bun” this time and didn’t serve him a burger salad right?
Are Burger Buns Healthy
I LOVE a good burger but burger buns are not typically considered to be healthy. Most burger buns are made from refined wheat flour, which is low in fiber and nutrients and can cause a rapid spike in blood sugar levels. They also often contain added sugars, preservatives, and other additives, which can contribute to a number of health issues.
That’s why I had to come up with healthier options. Let me to introduce you to a new kind of bun: my Sweet Potato Bun! If you didn’t know already, sweet potatoes are my jam, whether I’m cooking up some Twice-Baked Mexican Sweet Potatoes or incorporating them into a tasty dessert like Gluten-Free Sweet Potato Pie Bars, I always have them on hand. You’re not even going to miss the bun on these burgers because the sweet potato buns are absolutely DELISH.
How do you make Sweet Potato Buns from scratch?
Making these delicious and unique buns for your burgers isn’t as difficult as you might think! Sweet Potatoes bring the flavor and texture all on their own, with just a bit of help from some olive oil and salt! Here’s how to do it:
Using a sharp knife, cut 8 slices out of the middle of your sweet potato. It is the thickest part, so it makes for the biggest and best sweet potato buns.
Place your sweet potato slices into a large, microwave-safe bowl and add a splash of water to the bowl. Microwave on high just until the sweet potatoes start to soften, which should take about 2 minutes. Once heated, drain the water and pat each slice dry with a paper towel.
Brush each side of the slices of sweet potato and grill them until nice char marks form. This should take about 4 minutes. Flip and cook an additional 3-4 minutes or until they’re cooked and softened but not mushy.
Top each sweet potato bun with ketchup, veggies, and a burger, then finish it off with the remaining sweet potato bun. DEVOUR!
Ok, so now that I’ve shown you how EASY and DELICIOUS it is to make potato hamburger buns, let’s move on to the list of ingredients you’ll need to make these incredible burgers! Here you have it:
For the Veggies
- olive oil
- green pepper
- fresh garlic
For the Burgers
- 92% grass-fed beef
- Cajun seasoning
- sea salt
- olive oil
I also recommend making some low-carb sugar-free BBQ sauce to slather on!
How to Grill Burgers
Grilling your own burgers might seem intimidating, but fear not! It’s actually not scary but rather super simple and the flavor!? It can’t be beat! Here’s how:
- Set your grill to high heat.
- Once the grill is fully heated, place the burgers on the grill. Cook for 4 minutes.
- Flip the burgers and cook an additional 3-4 minutes or until they reach desires doneness. VOILA! Then, let them rest on a plate, covered in tin foil until ready to assemble and DEVOUR!
I recommend serving them with a side of my keto french fries for extra veggie goodness!
How long can I store Potato Buns for?
Sweet Potato buns can be stored in the fridge until you’re ready to use them, or if you have leftovers. They are best fresh off the grill, however if you want to store them in the fridge, they will keep for 2-3 days.
No-Bun Burger Variations
Here are a few ways to jazz up a hamburger:
- It’s all about the beef. Try using a mix of ground beef and ground pork or lamb for added depth of flavor. Or, if you’re on a health kick, you can substitute ground turkey, chicken, or plant-based meat substitutes.
- Experiment with herbs and spices. Try mixing in chopped fresh herbs, such as parsley, oregano, or thyme, or dried herbs, such as cumin, paprika, or garlic powder, for added flavor.
- Top the burger with flavorful condiments and toppings. Sky’s the limit here. Avocado, roasted red peppers, sautéed mushrooms, caramelized onions, or a fried egg would all complement the burger.
- Add cheese. I could have mentioned cheese in the previous point but I think it deserves its own. Blue cheese, Gorgonzola, or feta — or a mix of cheeses — add depth of flavor and a nice, creamy texture.
- If you want that smoky flavor, grill or cook the burger on a stovetop griddle or cast-iron skillet. This will help to sear the outside of the burger and create a crispy, caramelized crust.
