Prepare the garlic bread shell

• Slice the garlic bread loaf in half lengthwise and hollow out the inside, keeping the crust as a shell.
• Mix the softened butter with the minced garlic to make garlic butter.
• Brush the garlic butter all over the interior walls of the bread shell.
• Flip the bread and coat the exterior walls with garlic butter too.

Add Parmesan

• Sprinkle grated Parmesan over the outside of the garlic bread.
• Add a little Parmesan on the inside as well.

Build the brisket lasagna

• Place the garlic bread shell in the baking dish.
• Lay a thick slice of brisket inside the garlic bread.
• Pour barbecue sauce over the brisket.
• Add a layer of pre-cooked lasagna sheets.
• Top with slices of matured cheddar.
• Repeat with another slice of brisket, more lasagna sheets and barbecue sauce.
• Finish with a last layer of lasagna sheets, making sure everything is covered in sauce.

Top and bake

• Add a little more barbecue sauce on top.
• Scatter shredded mozzarella over the top, using the excess from the tray.
• Bake in the oven until the cheese is melted and golden, about 15 minutes.
