How to Make Zucchini Meatball Subs
-
Preheat your oven to 400°F and prepare two baking sheets with parchment paper. This will set the stage for a delicious and easy cleanup after your scrumptious meal!
-
Slice the ends off the zucchinis and carefully cut them in half lengthwise. Use a spoon to scoop out the seeds and some of the flesh, creating cozy little boats for your meatballs.
-
Brush the hollow zucchinis with olive oil on one of the baking sheets. This step helps them caramelize beautifully, bringing out their natural sweetness as they bake.
-
Mix the Italian sausage, egg, and grated parmesan together in a large bowl with your hands until well combined. Get your hands in there for ultimate mixing—this is where the magic begins!
-
Roll the mixture into 24 small meatballs, ensuring they’re all about the same size for even cooking. Place them neatly on the second prepared baking sheet, ready to bake!
-
Bake both trays in the preheated oven for 16-18 minutes. Check that the meatballs reach an internal temperature of 165°F and that your zucchinis are fork-tender.
-
Heat the spaghetti sauce in a large pan over medium flame. While your meatballs and zucchinis are baking, this will ensure the sauce is warm and ready to embrace your subs!
-
Remove any liquid that gathers in the center of each zucchini boat. This will keep your subs from getting soggy and allows the flavors to shine through.
-
Spoon a generous layer of sauce over each zucchini boat, then nestle 4 meatballs in each one, followed by another drizzle of sauce. Build that flavor, making each bite unforgettable!
-
Top each sub with 2 halves of provolone cheese, layering them evenly for that golden oozy goodness. Repeat this until all ingredients are used up and ready to melt!
-
Bake in the oven again just until the cheese melts to perfection, creating that irresistible bubbly, cheesy finish we all crave.
Optional: Garnish with fresh basil for a burst of flavor and color!

Expert Tips for Preparing Zucchini Meatball Subs
- Choose Fresh Zucchini: Select firm zucchinis for the best texture and taste. Overripe zucchinis can become mushy and spoil your hearty subs.
- Mix with Care: When combining the meatball ingredients, avoid overmixing. This can lead to tough meatballs; you want them light and tender!
- Avoid Soggy Subs: Make sure to scoop out enough flesh from the zucchini and drain any excess liquid before filling. This keeps your Zucchini Meatball Subs perfectly intact.
- Cook Evenly: Try to roll your meatballs to a uniform size. This ensures they cook evenly, resulting in delicious bites every time.
- Melted Cheese Bliss: Broil your subs for the last few minutes instead of baking to achieve that gooey golden top, but watch closely to prevent burning!
How to Store and Freeze Zucchini Meatball Subs
Fridge: Store leftover Zucchini Meatball Subs in an airtight container in the fridge for up to 3 days. Reheat in the microwave or oven for the best flavor.

Reheating: Thaw frozen subs in the fridge overnight before reheating in the oven at 350°F until warmed through, about 20 minutes.
Assembly: If you plan to freeze, consider assembling the subs without the cheese, then adding it right before baking for the freshest flavor.

I’m worried about soggy zucchini. How can I avoid that?
Great question! To prevent sogginess, ensure you scoop out enough of the zucchini’s flesh to create a deep boat while leaving some flesh for stability. Also, drain any liquid that pools in the center before filling with sauce and meatballs. This little step makes a huge difference!
