Ingredients for Stuffed Zucchini

• 1-2 tbsp olive oil, for cooking
• 1 small white onion, diced
• 1 medium carrot, diced
• 1 teaspoon salt, divided
• 1 teaspoon tomato paste
• 1 teaspoon ground cumin
• 1 teaspoon ground coriander
• ½ teaspoon smoked paprika
• 1 pinch red pepper flakes (optional)
• 1 cup chopped fresh tomatoes (or sub with chopped canned tomatoes)
• ½ cup water
• 1 15 oz can cooked lentils, rinsed and drained
• ¼ cup fresh herbs (such as basil or parsley)
• Freshly cracked black pepper
• 3 medium zucchini
• 1-2 tablespoon vegan parmesan or any other cheese you like such as mozzarella, cheddar, etc. (optional)

Make and Bake the Boats

1. Heat 1–2 tablespoons olive oil in a small pot or skillet over medium heat.
2. Add diced onion, diced carrot, and ½ teaspoon salt; cook 5–6 minutes until the onion is translucent and the carrots soften.
3. Stir in tomato paste, ground cumin, ground coriander, and red pepper flakes (optional); cook 1–2 minutes to bloom the spices.
4. Add chopped tomatoes, smoked paprika, rinsed and drained lentils, remaining salt, freshly cracked black pepper, and ½ cup water; bring to a boil, then reduce heat and simmer about 10 minutes until most liquid is absorbed.
5. Stir in chopped fresh herbs and remove the filling from heat.
6. Preheat oven to 350°F (180°C) and grease or line a baking dish.
7. Slice zucchinis in half lengthwise.
8. Scoop out seeds and some flesh from each zucchini half to create boats.
9. Spoon the lentil-tomato mixture evenly into each zucchini half.
10. Arrange the filled zucchini halves in the prepared baking dish.
11. Bake 25–30 minutes until the zucchinis are tender but still hold a slight bite.

12. In the last 5–10 minutes of baking, sprinkle vegan parmesan or your preferred cheese on top and return to the oven until the cheese melts and turns golden.

Tips for Best Results

• Go for canned lentils. They’re a huge time saver and work perfectly for this recipe.
• Cheese topping is flexible. Pick whatever you like—vegan parmesan, mozzarella, even cheddar works great here.
• Match your zucchinis. Choosing similar-sized zucchinis means they bake evenly and finish at the same time.
• Choose ripe tomatoes. Great tomatoes make a big difference here. If fresh ones aren’t available, canned tomatoes won’t disappoint.

Flavor Swaps and Add-Ins

• Switch up the protein: Try cooked quinoa, chickpeas, bulgur, or farro instead of lentils for a fun change.
• Not vegan? No worries—swap the lentils for cooked ground turkey or beef and top with regular cheese.
• Mediterranean vibes: Stir in chopped olives, capers, and crumble feta cheese instead of vegan parmesan.
• Bring the heat: Add harissa, chipotle in adobo, or more red pepper flakes to spice up the filling.
• Crunch factor: Mix panko breadcrumbs with olive oil and herbs, then sprinkle on top for the last 10 minutes of baking to get a golden crust.
• Feel like mixing veggies? Swap zucchini for yellow squash, hollowed bell peppers, or add diced mushrooms to the filling.
• If you want tomato-free: Replace fresh tomatoes with a small can of diced tomatoes or a few spoonfuls of marinara sauce.

Storage, Freezing, and Reheating

• Fridge: Cool zucchini boats fully, then store them in an airtight container for up to 3 days.
• Freezer: After cooling, layer the boats with parchment paper in between to stop sticking. Freeze for up to 3 months. Thaw overnight in the fridge before reheating.
• Reheat: Warm in a 350ºF (180ºC) oven for about 10 minutes, longer if frozen, until steaming hot all the way through.

Common Questions Answered

• Can I use dried lentils instead of canned? Absolutely! Just cook them fully following package instructions first. This recipe is built for convenience so canned lentils are easier but dried works fine too.
• How do I avoid soggy vegan stuffed zucchini boats? Scoop out seeds and excess flesh well, don’t overfill, and if your zucchinis are watery, salt the scooped shells and let them rest for 10-15 minutes before filling, then pat dry. You can also bake the hollowed shells for 5-8 minutes first to pull out moisture.
• Can I make these ahead or freeze before cooking? Yes, that’s a great idea! You can cook the filling and stuff the boats, then refrigerate for up to 24 hours before baking. For freezing, fully cooked boats freeze well, or freeze assembled unbaked boats and bake from thawed—just add some extra baking time if needed.
• What’s the best way to reheat leftovers? Oven reheating at 350ºF (180ºC) for about 10-15 minutes works great (longer if frozen). Microwaving is fine for a quick single portion, but will soften the zucchini more.
• What size zucchini is best? Medium zucchinis that are close in size will cook evenly and fit well in your baking dish.
• Are these vegan stuffed zucchini boats gluten-free? Yes! The basic recipe is naturally gluten-free. If you add any breadcrumb topping, just use gluten-free panko to keep it safe.
