Ingredients and Measurements

• 6 medium to large zucchini, all about the same size
• salt and pepper, to taste
• 1 cup low sodium chicken stock
• ¾ cup plain couscous
• 1 tbsp olive oil
• 1 lb Italian sausage
• 2 cloves garlic, minced
• 15 oz can petite diced tomatoes with garlic and oregano (undrained)
• ¼ cup fresh parsley, chopped
• 1 cup shredded mozzarella cheese
• freshly grated Parmesan, for serving
• freshly chopped basil, for garnish

Prep and Baking Steps

1. Preheat oven to 425°F and spray a 9×13-inch baking dish with nonstick spray.
2. Slice each zucchini lengthwise in half.
3. Use a spoon or melon baller to scoop out and discard seeds; scoop out flesh, chop it finely, and set aside.
4. Place hollowed zucchini halves cut side up in the prepared baking dish and season inside with salt and pepper.
5. Bring chicken stock to a boil in a small pot, remove from heat, stir in couscous, cover and let sit 5 minutes, then fluff with a fork.
6. Heat olive oil in a medium skillet over medium-high heat, add Italian sausage and chopped zucchini flesh, breaking up the sausage as it cooks until browned and zucchini is soft, about 4 minutes.
7. Stir in minced garlic and cook 30 seconds until fragrant, season with salt and pepper, then drain any excess grease.
8. Combine the cooked sausage mixture, cooked couscous, undrained diced tomatoes, and chopped parsley in a large bowl and stir to mix.
9. Spoon the filling evenly into each zucchini shell, allowing some filling to spill into the pan if necessary.
10. Top each stuffed zucchini with shredded mozzarella cheese.

11. Bake for about 25 minutes or until zucchini is tender and cheese is golden and bubbly.
12. Sprinkle with freshly grated Parmesan and chopped basil before serving.

Helpful Tips and Tweaks

• Use gentle scraping: A small spoon or melon baller works best to scoop out zucchini seeds and flesh without breaking the sides.
• Don’t over-scoop: Remove enough zucchini flesh so it cooks well, but keep the shells sturdy so they hold the filling without collapsing.
• Love bacon? Try swapping the sausage for cooked, crumbled bacon or use both for extra flavor.
• Vegetarian twist: Leave out the sausage and sauté chopped mushrooms and bell peppers with the reserved zucchini flesh for a meatless option.
• Feeling adventurous? Spice it up with taco seasoning and swap the tomatoes for salsa for a tasty Mexican version.

Easy Swaps and Variations

Want to mix things up or work with what you have? Here are some easy ways to change up this stuffed zucchini recipe:

• Make it gluten-free: Swap couscous for cooked quinoa in a 1:1 ratio — just cook the quinoa according to package directions.
• Go vegetarian: Skip the sausage and sauté your favorite mushrooms and bell peppers with the reserved zucchini flesh for a tasty plant-based filling.
• Try other meats: Use cooked, crumbled bacon or ground turkey or chicken instead of Italian sausage for different flavors.
• Mexican-style: Add taco seasoning to the filling, replace the tomatoes with salsa, and top with cheddar or Monterey Jack cheese.
• Swap the cheese: Use provolone, fontina, or mix mozzarella and Parmesan for different melty textures and tastes.
• Smaller bites: Make mini zucchini boats or halve baby zucchinis for tasty appetizers or party snacks.
• Drain the tomatoes: If your canned tomatoes are extra juicy, drain some of the liquid before mixing so your stuffing isn’t soggy.

Storage and Reheating Tips

Heads up—stuffed zucchini doesn’t freeze well. When thawed, zucchini can get watery and mushy, which just isn’t very appetizing. But don’t worry, leftovers can still shine!

Once they’ve cooled, store any extra stuffed zucchini in an airtight container in the fridge for up to 3 days. After that, the cheese can start to get a little slimy. You can keep them individually packed for meal prep or together in a casserole dish.

To reheat, pop the zucchini in an oven-safe dish and warm in a 350°F oven for about 20 minutes or until they’re heated through and the cheese is melty again.

Common Questions Answered

1. Can I make this vegetarian?

   Absolutely! Just skip the sausage and sauté the reserved zucchini flesh with chopped mushrooms and bell peppers (or other vegetables you like) as directed, then mix with couscous and tomatoes.

2. Is there a gluten-free option?

   Yes, swap the couscous for cooked quinoa or another gluten-free grain. Quinoa cooks differently, so follow package directions and fold it into your filling once it’s done.

3. Can I prepare these ahead of time?

   Yes, you can assemble the stuffed zucchini in your baking dish, cover it with foil, and keep it in the fridge for a few hours before baking. Just add extra bake time if you bake it cold from the fridge.

4. Do these freeze well?

   No, freezing isn’t recommended. Zucchini releases water as it thaws, which makes the dish mushy. Instead, store leftovers in the fridge for up to 3 days and reheat in the oven to keep things tasty.

5. How do I know when the zucchini is done?

   It’s done when it’s tender enough to easily pierce with a fork and the cheese on top is melted and golden. That usually takes about 25 minutes at 425°F.

6. How can I prevent soggy zucchini boats?

   Make sure not to scoop out too much flesh so the shells keep their shape. Also, if your canned tomatoes are very juicy, drain some of the liquid before mixing to keep the filling from being too wet.

7. How many does this recipe serve, and what are the cook times?

   This recipe makes about 12 zucchini halves. Prep time is about 15 minutes and cooking takes roughly 35 minutes, so total time is around 50 minutes.
