Preheat your oven to 375°F (190°C).

Using a sharp knife, slice off the top of the sourdough loaf to create a lid and hollow out the inside.

In a mixing bowl, combine softened cream cheese with shrimp, crab meat, garlic powder, lemon juice, and herbs. Mix until smooth.

Fold in the shredded cheddar cheese until the mixture is combined.

Spoon the filling into the hollowed sourdough loaf, packing it in gently.

Place the stuffed bread bowl on a baking sheet and bake for 25-30 minutes until golden brown and bubbly.

Remove from the oven, let cool for a few minutes, then slice or serve whole with vegetables or crackers.
