A hearty, all-in-one dinner featuring tender zucchini boats filled with a juicy, seasoned ground beef mixture and topped with melted cheese. The secret to a perfectly moist filling is a simple panade technique using breadcrumbs mixed directly with the beef.
For a gluten-free version, use gluten-free breadcrumbs or rolled oats. Do not skip mixing the breadcrumbs with the raw beef (the panade), as this keeps the filling juicy. Letting the boats rest for 5 minutes after baking makes them easier to serve.
