What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Scoop out the zucchini flesh carefully, leaving a 1/4-inch thick shell so the boats hold their shape during baking.
- 2Be sure to salt the zucchini shells and let them rest 10 minutes before stuffing to draw out excess moisture and prevent a soggy bottom.
- 3Cook the lentils until just tender—overcooking will make them mushy and the filling less textured.
- 4For the best flavor, sauté the tomato paste with the aromatics until it darkens slightly before adding the tomatoes.
- 5Pack the lentil filling gently but firmly into each shell to prevent the boats from falling apart as they bake.
- 6Leftover stuffed zucchini boats keep well in the fridge for up to 3 days; reheat in a 350°F oven to crisp the tops.
