Do you grill zucchini with the skin on?
Yes. The only reason to peel the skin is if the zucchini is waxed to preserve shelf life.
The skin can be bitter on larger and older zucchini so look for zucchini that is about 4-6 inches long (10-15cm).
How long does it take to cook zucchini on the grill?
Zucchini (sliced lengthwise, with skin on) takes from 10-15 minutes to cook on the grill, depending on the heat level.
How do you make stuffed zucchini or zucchini boats?
- Preheat your grill to 375°F (190°c). This is a medium heat. Wash and dry the zucchini.
- Cut off the ends of the zucchini and use a small spoon to scrape out the seeds. This creates a nice groove in the center of the zucchini where you can place tasty fillings. Try not to scrape out the section at both ends of the zucchini. That way, the fillings won’t spill out the ends. (Image 2)
- Brush the cut side of the zucchini with olive oil and place skin side up on the grill to cook for 10-12 minutes. Test with a fork or sharp knife for tenderness. When the knife goes in easily, they are cooked.
- While the zucchini is cooking, prepare the fillings. Grab some pesto (store-bought or homemade), mozzarella (sliced or shredded) and shredded parmesan cheese. Slice the grape tomatoes in half and snip some fresh basil leaves. Have your toppings assembled and ready to place into the zucchini wells.
- Turn over the zucchini when it’s cooked (10-12 minutes) and place it on a grill safe pan or onto foil to avoid the toppings falling into the grill. Spread the pesto equally along each zucchini. Add the cheeses and tomatoes on top of the pesto and grill until the cheese is melted and gooey (3-4 minutes). The other way to finish this dish is to remove the cooked zucchini onto a plate and add the toppings there. Place the zucchini with toppings back onto the grill (onto foil) or onto the hot plate (without foil), if your barbecue has one to finish cooking. Sprinkle the zucchini boats with slivers of basil.
Cooking tips and tricks for Grilled Caprese Stuffed Zucchini Boats
- You can place zucchini on a grill safe pan or foil before adding toppings to keep the cheese from dripping into the grill
- Alternatively, remove cooked zucchini to a plate and add toppings there. Place back on the grill (using grill safe pan or foil) or place zucchini onto a hot plate if your barbecue has one. This avoids having to worry about using foil as any drips can be easily cleaned up on a hot plate.
- How to cook in the oven – place zucchini with seeds scooped out onto a baking tray lined with parchment paper. Add the toppings and bake, uncovered at 350°F (175°c) for 25-30 minutes or until zucchini is tender.
- Zucchini boats can be cooked on a grill pan on the stovetop – cook on high heat for 5-10 minutes or until zucchini is soft when you stick a fork into it. Flip and add topping ingredients and continue to cook until melted.
- Zucchini boats can be easily customized to suit your tastes or individuals in your family. Anything goes really, as long as you have some cheese to melt. Think olives, bell peppers, thinly sliced mushrooms etc. While this is a vegetarian version, cooked meat could also be added eg. cooked ground beef, ham, turkey, pepperoni. Anything you would add to a pizza works well.
