What Are Zucchini Boats?
If you’ve never made stuffed zucchini, you’re in for a treat.
Zucchini boats are simply:
- Large zucchinis sliced in half lengthwise
- The center scooped out (a melon baller works perfectly!)
- Then filled with a delicious mixture like this chicken fajita stuffing
They’re one of the easiest ways to turn vegetables into a complete meal—and a great alternative to zucchini noodles or pasta.
Zucchini is the king of all vegetables in my opinion when summer comes. It’s so easy to create fabulous low carb recipes without much work in the kitchen. This recipe is the perfect example!
Pro Tips for the Best Zucchini Boats
These simple tips will take this great recipe to the next level:
Prevent Excess Moisture
Zucchini naturally holds water, so:
- Don’t over-scoop the center
- Pre-baking helps reduce excess moisture
- You can lightly salt the zucchini before baking to draw out water
Use the Right Size Zucchini
- Choose large zucchinis for sturdy boats
- Avoid overly large ones with tough zucchini skin
Sheet Pan Success
- Spread chicken and veggies evenly on the baking sheet
- Don’t overcrowd—this helps everything roast instead of steam
Easy Swaps and Variations
This recipe is incredibly flexible depending on your preferences or what you have on hand.
Protein Swaps
- Use ground chicken or ground turkey
- Try ground beef for a richer flavor
- Use leftover chicken or rotisserie chicken for a faster version
Dairy-Free Option
- Skip the cheese or use dairy-free alternatives
- Replace sour cream with dairy-free options
Add More Flavor
- Add tomato sauce or pasta sauce for a saucier filling
- Toss in black olives or jalapeños for extra kick
For the Family
If your kids aren’t into zucchini:
- Serve the filling in traditional tacos by the brand Siete
- Use my cheesy taco shells or these wraps for the kids
This makes it a win-win meal for everyone at the dinner table. Here’s my own homemade taco seasoning to make ahead and have on hand whenever you want fajitas or tacos!
If you need an even quicker recipe that doesn’t include zucchini, these are my sheet pan chicken fajitas will be perfect! Or maybe my chicken taco soup is what you’re feeling like.
