Begin by heating olive oil in a large skillet over medium heat. Add your diced onion and bell pepper, cooking them until soft and fragrant. These veggies create a flavorful base that sets the stage for the bold Cajun spices to shine.

Stir in minced garlic and cook for an additional minute to release its aroma. Add the ground chicken to the skillet, breaking it up as it cooks. Keep stirring until the chicken is no longer pink and is evenly browned. This ensures every piece is tender and infused with flavor.

Once the chicken is cooked, mix in the tomato sauce, ketchup, Worcestershire sauce, Cajun seasoning, smoked paprika, salt, and pepper. Stir everything together, ensuring the sauce completely coats the chicken. Allow it to simmer for about 10 minutes, letting the flavors meld into a rich, irresistible mixture.

While the chicken mixture simmers, lightly toast your hamburger buns. Toasting helps prevent the buns from getting soggy and adds a subtle crunch that pairs perfectly with the saucy filling.

Spoon a generous portion of the Cajun chicken mixture onto the bottom halves of your toasted buns. Add optional toppings like pickles, shredded cheese, or coleslaw for an extra layer of flavor and texture. Top with the other half of the bun, serve immediately, and enjoy!
