1-First Step: Mise en place and oven prep Preheat the oven to 350°F and line a baking sheet with parchment paper. Gather all ingredients so you can move through the steps without stopping. If using raw tenderloins, pat the chicken dry with paper towels to help the seasoning stick.

2-Second Step: Season and cook the chicken Drizzle the chicken with 1 tablespoon olive oil and rub or coat evenly with 3 tablespoons Cajun seasoning. Heat a skillet over medium heat with 2 tablespoons olive oil. Add the seasoned chicken and cook for 4-5 minutes on the first side. Reduce heat to low for the second side and cook an additional 3-4 minutes, until the chicken is cooked through and reaches a safe internal temperature. Remove from the skillet and let rest for a few minutes before slicing into bite-sized pieces. If you are using rotisserie chicken, shred or chop 2 cups and toss briefly in the hot skillet with a splash of olive oil and a pinch of Cajun seasoning to warm and flavor the meat.

3-Third Step: Make the Cajun Alfredo sauce Using the same skillet helps keep flavor from the chicken. Melt 2 tablespoons softened butter over medium-low heat. Add 3 minced garlic cloves and sauté until fragrant, about 30-45 seconds. Pour in 1.5 cups heavy cream and add 2 teaspoons Cajun seasoning. Bring the cream to a low simmer and let it cook for 5 minutes until slightly thickened, stirring occasionally. Stir in 1/2 cup grated or shredded Parmesan cheese until it melts into a smooth sauce. Season with salt and pepper to taste. Remove from heat and set aside.

4-Fourth Step: Prepare the garlic butter and toast the bread Combine 5 tablespoons softened butter, 3 minced garlic cloves, 1 teaspoon red pepper flakes (if using), and 2 teaspoons minced fresh parsley in a small bowl. Microwave 5-10 seconds or stir until the mixture is spreadable. Slice the loaf of bread lengthwise and spread the garlic butter evenly across both halves. Place the halves on the prepared baking sheet and bake at 350°F for 5-10 minutes until the bread is lightly toasted and the edges begin to turn golden. This pre-toast step helps prevent sogginess once you add toppings.

5-Fifth Step: Assemble the Alfredo Chicken Bread* Place the toasted bread halves on the baking sheet, cut sides up.* Layer each half with 1 cup shredded Parmesan cheese (half of the 2 cups total), spreading evenly.* Scatter the sliced or shredded chicken over the cheese layer.* Top the chicken with the remaining 1 cup shredded Parmesan.* Drizzle about 1/3 cup of the Alfredo sauce over each bread half, distributing it so each bite has a creamy hit.

6-Final Step: Bake, broil if desired, slice, and serve Bake the assembled bread at 350°F for 5-10 minutes, or until the cheese is melted and the edges of the bread are golden. If you want a bubbly, slightly charred top, switch the oven to broil and broil 1-2 minutes while watching closely to avoid burning. Remove from oven and let rest 2-3 minutes to set, then slice into 2-inch pieces and serve with the remaining Alfredo sauce for dipping.
