In a large mixing bowl, combine the sausage meat, breadcrumbs, chopped onion, minced garlic, sage, thyme, and the beaten egg. Season with salt and pepper. Mix until all ingredients are well combined.

On a piece of parchment paper or a clean surface, shape half of the sausage mixture into a rectangular or square shape, about 1-inch thick.

Place the black pudding log in the center of the sausage layer.

Cover the black pudding with the remaining sausage mixture, ensuring it's fully encased. Shape the mixture around the black pudding to form a compact loaf.

To create a more square loaf, use your hands or a square baking tin lined with parchment paper. Press the sausage mixture firmly into the square shape, ensuring the black pudding is centered.

Preheat your oven to 180°C (350°F).

Place the square sausage loaf on a baking tray lined with parchment paper or in a greased square loaf tin.

Bake in the preheated oven for 45-55 minutes, or until the sausage meat is cooked through and the top is golden brown. The internal temperature should reach 70°C (160°F).

Allow the loaf to rest for about 10 minutes before slicing. This helps it hold its shape.

Slice the loaf to reveal the black pudding center, and serve with your favorite sides, such as mashed potatoes, gravy, or vegetables.
