Ingredients
Method
- Preheat the oven: Set your oven to 400°F (200°C). Line a baking sheet or 9x13-inch baking dish with parchment for easy cleanup.
- Prep the zucchini: Trim the ends, slice each zucchini lengthwise, and use a spoon to scoop out the centers, creating boats. Leave about 1/4-inch border so they hold their shape. Chop the scooped zucchini flesh and set aside.
- Season and par-bake: Brush the zucchini boats with olive oil, sprinkle with salt and pepper, and place them cut side up. Bake for 10–12 minutes to soften slightly.
- Cook the beef: While the zucchini bakes, heat a large skillet over medium-high heat. Add a drizzle of oil, then the onion. Cook 3–4 minutes until softened. Add garlic and cook 30 seconds.
- Brown and season: Add the ground beef. Break it up and cook until browned, 5–7 minutes. Drain excess fat if needed. Stir in taco seasoning and tomato paste. Cook 1 minute to bloom the spices.
- Add moisture and mix-ins: Stir in the chopped zucchini flesh and the fire-roasted tomatoes (drained). Cook 3–4 minutes until most liquid evaporates. Fold in black beans or corn if using. Taste and season with salt and pepper.
- Fill the boats: Remove zucchini from the oven. Spoon the beef mixture into each boat, packing it in. Top with shredded cheese.
- Bake to finish: Return to the oven for 8–10 minutes, until the cheese is melted and the zucchini is tender but not mushy.
- Garnish and serve: Sprinkle with cilantro or green onions. Squeeze fresh lime over the top. Add salsa, avocado, or a dollop of sour cream if you like.

Keeping It Fresh
- Storage: Let leftovers cool, then store in an airtight container for up to 3–4 days.
- Reheating: For best texture, reheat in a 350°F (175°C) oven for 10–12 minutes or until warmed through. The microwave works in a pinch—about 60–90 seconds per piece.
- Make-ahead: Prepare the beef filling up to 3 days in advance.
Stuff and bake when you’re ready to eat.
- Freezing: Freeze the cooked beef filling on its own for up to 2 months. Avoid freezing assembled zucchini, as they release water when thawed.
Benefits of This Recipe
- Vegetable-forward: Zucchini adds volume, fiber, and nutrients while keeping things light.
- High in protein: Ground beef makes it satisfying and keeps you full longer.
- Flexible for diets: Easy to make low-carb or gluten-free. Skip the beans if you’re watching carbs; use low-sodium seasoning if needed.
- Budget-friendly: Uses simple, affordable ingredients with big flavor payoff.
- Kid-approved: Feels like taco night, just in a fun, new form.
What Not to Do
- Don’t skip draining fat: Excess grease makes the filling heavy and soggy.
- Don’t overbake the zucchini: Mushy boats fall apart.
Aim for tender with a little bite.
- Don’t add too much liquid: Drain tomatoes and don’t overdo salsa in the filling. Wet filling leads to watery results.
- Don’t forget to taste: Adjust seasoning after adding tomatoes and zucchini. A pinch of salt and a squeeze of lime brighten the flavors.
- Don’t overpack with cheese: A generous layer is great, but too much can make the top greasy instead of melty.
Alternatives
- Protein swaps: Use ground turkey, chicken, or plant-based crumbles.
Chorizo adds a spicy twist.
- Cheese options: Try Oaxaca, queso quesadilla, or a blend of cheddar and pepper jack. For dairy-free, use your favorite vegan shreds.
- Low-sodium spin: Make homemade taco seasoning and use no-salt-added tomatoes.
- Extra veggies: Add diced bell pepper, mushrooms, or spinach to the filling for more color and nutrients.
- Different bases: Swap zucchini for halved bell peppers or hollowed-out small eggplants. Adjust baking time as needed.
- Spice level: Add chipotle powder, cayenne, or minced jalapeño to the beef for extra heat.
FAQ
Do I have to pre-bake the zucchini?
Par-baking helps the zucchini soften so it’s tender by the time the cheese melts.
If you skip it, the zucchini may be too firm or the filling could dry out while you wait for it to cook.
Can I make this without cheese?
Yes. Skip the cheese or use a dairy-free alternative. For extra richness without dairy, drizzle a little olive oil and finish with avocado and a squeeze of lime.
How do I keep the zucchini from getting watery?
Scoop out the seeds, pre-bake, and make sure the filling isn’t too wet.
Drain tomatoes well and simmer the mixture so excess moisture evaporates.
What’s the best way to serve it?
Serve with a simple side salad, cilantro-lime rice, or cauliflower rice. Add salsa, hot sauce, and lime wedges at the table so everyone can adjust the flavors.
Can I double the recipe?
Absolutely. Use two baking dishes or bake in batches.
Keep the zucchini in a single layer so they cook evenly.
Is this freezer-friendly?
Freeze the cooked beef filling only. Assembled zucchini don’t freeze well—they release water when thawed and can become mushy.
What if my zucchini are huge?
Large zucchini work fine. You may need to bake them a few minutes longer and add more filling.
If they’re extra thick, scoop a deeper channel to help them cook evenly.
Can I use homemade taco seasoning?
Yes. A simple blend is chili powder, cumin, paprika, garlic powder, onion powder, oregano, salt, and pepper. Adjust heat with cayenne or chipotle.
How can I make it lighter?
Use lean ground turkey, reduce the cheese, and load up on fresh toppings like salsa, tomatoes, and shredded lettuce.
Greek yogurt is a great swap for sour cream.
