First Step: Preheat Oven and Prepare Bacon
Preheat your oven to 180°C (350°F). Heat a small amount of oil in a skillet over medium-high heat. Add diced bacon (or pre-cooked bacon) and cook until lightly browned but not overly crispy to maintain tenderness. Drain excess fat and allow the bacon to cool.

Second Step: Prepare the Baguette and Filling
Cut the baguette lengthwise almost halfway through or into quarters for easier handling, leaving about a ½-inch (1.5 cm) thick wall to preserve structure. Carefully hollow out the inside bread without puncturing the crust, reserving any excess bread for breadcrumbs if desired.

Third Step: Make the Cheese and Jalapeno Mixture
In a large bowl, combine softened cream cheese, shredded cheddar and mozzarella, finely chopped jalapenos, scallions, cooled bacon, black pepper, and a pinch of salt. Mix until creamy and evenly blended.

Fourth Step: Stuff the Baguette
Fill the hollowed baguette sections evenly with the cheese and bacon mixture, pressing gently to distribute the stuffing. Use a knife or piping bag for easier filling and to prevent spills.

Fifth Step: Make Garlic Butter and Prepare for Baking
Melt softened butter with minced garlic (either in the microwave or on stovetop) and add a pinch of salt. Brush this flavorful garlic butter generously over the top and sides of the stuffed baguette, enhancing aroma and creating a golden crust.

Final Step: Bake and Serve
Carefully close the baguette if sliced lengthwise and cut into ½-inch (1.25 cm) thick slices without cutting all the way through, so the pieces remain connected. Press slices together firmly. Wrap tightly in aluminum foil and place on a baking sheet.
Bake for 15 to 20 minutes until the bread is crusty and the cheese filling is melted and gooey. Unwrap and bake uncovered for an additional 5 minutes if you prefer a crispier crust. Serve warm for best flavor and texture.
