Ingredients and Substitutions

• 4 large zucchini (about 6 oz. each), halved lengthwise
• ½ pound lean ground beef or turkey
• ½ cup diced onion (about 1 medium yellow onion)
• ¼ teaspoon kosher salt
• ⅛ teaspoon coarse ground black pepper
• 2 cloves garlic, minced
• 1 cup marinara or spaghetti sauce
• 1 cup ricotta cheese
• 1 large egg, beaten
• ½ cup grated Parmesan cheese
• 2 tablespoons finely minced fresh parsley, plus more for garnish
• 1 tablespoon finely minced fresh basil, plus more for garnish
• ½ teaspoon garlic powder
• ½ teaspoon dried oregano
• ⅛ teaspoon coarse ground black pepper
• 1 cup shredded mozzarella cheese

Assembly and Baking Instructions

1. Preheat oven to 400°F and lightly spray a 9×13-inch baking dish with nonstick spray.
2. Slice 4 large zucchini in half lengthwise.
3. Using a spoon, scoop out the centers of each zucchini half, leaving a 1/4-inch thick shell.
4. Place zucchini cut-side down on paper towels and drain 10–15 minutes; sprinkle insides with a little salt and pat dry to avoid sogginess.
5. In a skillet over medium-high heat, cook 1/2 pound ground beef and 1/2 cup diced onion with 1/4 teaspoon kosher salt and 1/8 teaspoon black pepper, breaking up the meat, until beef is browned and onions are soft.
6. Drain excess grease if needed.
7. Stir in 2 cloves minced garlic and cook 1 minute until fragrant.
8. Stir in 1 cup marinara sauce and remove the skillet from the heat.
9. In a bowl, mix 1 cup ricotta cheese, 1 beaten large egg, 1/2 cup grated Parmesan, 2 tablespoons minced parsley, 1 tablespoon minced basil, 1/2 teaspoon garlic powder, 1/2 teaspoon dried oregano, and 1/8 teaspoon black pepper until creamy.
10. Place the hollowed zucchini halves in the prepared baking dish.
11. Evenly spread the ricotta mixture into the hollowed zucchini halves.
12. Spoon the meat sauce evenly over the ricotta-filled zucchini halves.
13. Cover the baking dish with foil and bake at 400°F for 35 minutes.

14. Remove the foil, top each zucchini boat with 1 cup shredded mozzarella, and bake uncovered 5–10 minutes until cheese is melted and zucchini is tender.

Chef Tips for Success

• Pick medium zucchinis around 8 inches long — smaller ones don’t hold much filling and bigger ones tend to be watery and need longer to cook.
• Once you scoop out the centers, set your zucchini cut side down on paper towels to drain for 10–15 minutes. Sprinkle a little salt on the insides and pat dry to avoid sogginess.
• Don’t toss the scooped-out zucchini flesh! Chop it finely and sauté with your meat or mix it into your ricotta filling for extra flavor and no waste.
• Avoid drowning your boats in sauce to keep them from getting soggy. A moderate spoonful over the cheese is just right.
• Use low-moisture mozzarella or briefly pat shredded cheese dry if it feels wet — this helps with melting and browning without excess water.
• If you use cottage cheese instead of ricotta, drain it well first so your filling stays thick and creamy.
• Cover the dish with foil during the first bake to tenderize zucchini evenly, then uncover at the end to melt and brown cheese beautifully. For even more golden tops, broil for 1–2 minutes but watch carefully.
• Choose no-sugar-added marinara to keep this recipe keto-friendly.
• Add extra veggies by sautéing mushrooms, spinach, or bell peppers with the meat or on their own, then mix them into the sauce or cheese filling for more color and nutrition.
• If you want to prep ahead, assemble the boats but keep them unbaked in the fridge up to 24 hrs. Add about 5 extra minutes to baking time when cooking from chilled.

Flavor Variations and Swaps

• Meats: Swap ground beef for Italian sausage or ground chicken for a taste twist.
• Cheese: Cottage cheese is a great ricotta stand-in if you prefer a lighter texture.
• Vegetarian: These zucchini boats shine without meat, too! Load up the filling with extra ricotta, Parmesan, and sautéed veggies for a fully satisfying meatless meal.

Storing, Freezing, and Reheating

You can make these zucchini lasagna boats ahead by stuffing but not baking. Just cover tightly and refrigerate for up to 24 hours. When you’re ready, pop them in the oven, adding 5 minutes to bake time for a perfectly cooked dish.

Refrigerating leftovers: Store any extras in an airtight container in your fridge for up to 3 days. They taste great cold or reheated the next day.

Reheating tips: Warm them up in the microwave in one-minute bursts to avoid overcooking. Or for better texture, reheat covered in a 350°F oven for 10–15 minutes until heated through, then uncover for a few minutes to refresh the cheese.

Answers to Common Questions

• Can I freeze zucchini boats? Absolutely. Freeze cooked boats for up to 2 months. For best results, leave off the mozzarella before freezing and add fresh cheese when reheating. Thaw overnight in the fridge, then reheat in a 350°F oven until hot all the way through.
• Can I make these vegetarian? Yes! Just ditch the meat and bulk up the filling with sautéed mushrooms, spinach, eggplant, or extra ricotta and Parmesan for a hearty vegetarian meal.
• How do I keep zucchini boats from getting soggy? Drain the zucchini well after scooping, avoid adding too much sauce, use low-moisture cheese, and bake covered at first, uncovering toward the end so extra moisture evaporates.
• Can I use yellow squash or other summer squash? Yes! Yellow squash and pattypan squash work similarly. Just keep an eye on baking times if the squash is much thicker or thinner than zucchini.
• How do I know when they’re done? The zucchini should be tender enough to pierce easily with a fork and the filling hot. After removing the foil, the cheese should be melted and lightly browned.
• Can I double this recipe? Yes, just use a larger baking dish or two pans. A crowded pan might need a few more minutes to bake fully.
• Is there a better way to reheat leftovers than the microwave? I recommend reheating covered in a 350°F oven for 10–15 minutes, then uncovering for a few minutes to revive that melty cheese texture. This keeps the zucchini firmer than the microwave.
• Can I use pre-shredded cheese? You can, but fresh-shredded mozzarella melts smoother because pre-shredded usually has anti-caking additives that can affect how it bakes and tastes.
