Grilled Cajun Chicken Sandwich Recipe

A picture says a thousand words, so you probably already know what to expect from these grilled Cajun chicken sandwiches just by what you see here, but in case you'd like a few more words on the matter, take it from chef and recipe developer Susan Olayinka of The Flexible Fridge, who says, "They tasted so good! We are chicken breast fans in our house and we're also huge spice fans so this recipe was a great match."

And in more good news, these tasty sandwiches are hardly a challenge. "This is definitely easy," Olayinka tells us, adding, "You just season the meat, [and] Cajun season is a blend of seasonings which makes it much easier, too. And then all that's left is to put it on the BBQ." (Don't have handy access to a grill? You can cook the chicken in a cast iron pan or even just roast it in the oven — the texture may be a bit different but the taste will remain intact.)

Ready for a savory sandwich the whole family will enjoy? Let's dig in!

Gather your ingredients

This recipe is pretty simple in terms of prep and ingredients. All you need is chicken breasts, Cajun seasoning, olive oil, salt, a tomato (a beefsteak tomato works best), a head of romaine lettuce, and four brioche buns (assuming you're making four sandwiches).

Want to add some Louisiana hot sauce to the recipe? Well that's a fine idea: you can drip some onto the buns or drench the chicken in it before grilling. Want to add some cheese? Well don't — that's overdoing it. Less is more here.

Season and grill the chicken

Begin the recipe by slicing the two chicken breast into halves, cutting along the long side of each breast, as if you were going to butterfly them (but slice them all the way through). This will make them thinner. Then put them into a mixing bowl. Add to said mixing bowl the Cajun seasoning and salt, both sprinkled over the meat, and the olive oil, drizzled on. Use a spoon or your hands to toss the chicken and ensure it gets coated in the spices.

Now place the chicken onto a grill going at a medium heat and grill it on one side for 10 minutes. You will know when it's ready to be turned over once the chicken stops sticking to the grill — pulling it away will be very easy. Use a metal spatula to turn it over (or tongs, but be gentle) and grill the other side. After eight to 10 minutes on this second side, the chicken should be cooked, but you might want to check to make sure the internal temperature is 165 F. You can set it aside for a moment.

Prep your toppings and buns

Once the chicken is cooked and off the grill (or while it's cooking, if you're the multitasking type), slice the tomato to produce four thick discs, each about ¼-inch thick. Now slice the romaine into halves and remove the bottom section of the lettuce. You can use one, two, or three leaves per sandwich, depending on one's preference.

Finally, slice the buns in half if they're not pre-cut and set the halves beside one another.

Assemble the sandwiches

To assemble the sandwich, start with the bottom half of a bun and place one slice of tomato down onto it, then add a piece of grilled chicken, then finally place the lettuce leaves on the chicken and then close the sandwich. And then enjoy!

Note that a toothpick or little skewer can help prevent the sandwiches from falling apart before they're eaten. And for serving ideas, "Fries/chips would be great," Olayinka suggests, adding: "Sweet potato fries would be even better or even some mashed potato, or perhaps a salad."
