Every summer, when my mom's garden is overflowing with zucchini, these stuffed zucchini boats are one of the first recipes we make. Tender zucchini is filled with a savory mixture of lean ground turkey, marinara, herbs, and melty mozzarella, creating a dinner that's hearty enough to satisfy but still feels light and fresh. Best of all, each serving packs an impressive 38 grams of protein, making it an easy way to get a healthy, satisfying meal on the table.
This is one of those weeknight recipes you'll come back to again and again. The filling comes together in a single skillet, the zucchini bakes until perfectly tender, and leftovers taste just as good the next day. If you're looking for more protein-packed dinners, be sure to try my quinoa fried rice with garlic butter chicken is another one worth bookmarking, and you'll find more like it in my high-protein dinner recipes roundup.

Why You'll Love This Recipe
This isn't just a lighter spin on stuffed peppers - it earns its own spot in the weeknight rotation.
- High-protein, not heavy. Bison and quinoa together pack a serious protein hit without the greasy finish you get from ground beef.
- Bison is leaner than beef. Same hearty, savory flavor, with a lot less fat left behind in the pan.
- One skillet, one dish. The filling comes together in a single pan before it goes into the oven - minimal cleanup.
- Freezer-friendly. Double the filling and freeze half for a night you don't feel like cooking at all.
- Kid-approved. Melted cheese on top hides a lot of vegetables.
How to Make Stuffed Zucchini Boats
Seven steps, and most of them are hands-off while the skillet or the oven does the work.
Sauté the Aromatics
Preheat your oven to 375°F so it's ready when the zucchini go in. Meanwhile, in a large skillet over medium heat, sauté the onion and garlic until softened, about 3-4 minutes.
Brown the Bison
Add the ground bison, season with salt and pepper, and cook until browned, breaking it up as it cooks, about 6-8 minutes.
Build the Sauce
Stir in the tomato paste and beef stock, then simmer for 15-20 minutes.
Fold in the Quinoa and Cheese
Fold the cooked quinoa into the skillet along with half of the mozzarella and parmesan.
Stuff the Zucchini
Stuff the mixture into the hollowed zucchini and arrange them in a baking dish. Top with the remaining cheese.
Bake
Cover with foil and bake for 25-30 minutes, then uncover and bake 5-10 minutes more, until the zucchini is tender and the cheese is golden.
Garnish and Serve
Garnish with fresh parsley or cilantro before serving.
Substitutions
A few easy swaps if you're working with what's already in your kitchen.
- Ground beef or ground turkey instead of bison - either works, just drain off excess fat if you use beef.
- Rice instead of quinoa - cooked white or brown rice subs in at the same amount.
- Dairy-free cheese instead of mozzarella and parmesan - look for a shredded blend that melts well.
- Chicken stock instead of beef stock, if that's what you have on hand.
Variations
Once you've made this a couple of times, here's where you can start to play with it.
- Bell peppers instead of zucchini. This filling actually started as a stuffed pepper recipe - swap in 4 bell peppers, tops removed and seeded, if that's what you've got. They're thicker-walled than zucchini, so give them closer to 35-40 minutes covered before uncovering to finish.
- Spicy version. Stir a spoonful of chipotle in adobo or a pinch of red pepper flakes into the filling.
- Tex-Mex style. Swap the parmesan for pepper jack and top the baked boats with sour cream and diced avocado.
- Lower-carb. Skip the quinoa altogether and add an extra half pound of bison in its place.
Equipment
Nothing complicated here - just the basics that make browning, hollowing, and baking easier, plus a couple of upgrade picks worth the money.
- Large Stainless Steel Skillet (Premium) - A wide, heavy-bottomed 12-inch skillet browns the bison evenly instead of steaming it in its own liquid.
- Tramontina Tri-Ply Skillet (Budget) - A non-toxic stainless option that performs almost as well for a fraction of the price.
- 9x13 Ceramic Baking Dish (Premium) - Holds heat evenly so the zucchini bakes through without drying out at the edges.
- Pyrex 9x13 Glass Baking Dish (Budget) - Simple, oven-safe, and easy to clean - does the job every time.
- Melon Baller (Premium) - Makes quick, clean work of hollowing the zucchini without tearing through the shell.
- Stainless Steel Spoon Set (Budget) - A sturdy spoon works fine for hollowing if you go slow and steady.
- Stainless Steel Mixing Bowl Set (Premium) - Non-toxic and roomy enough to fold the quinoa and cheese into the filling without spilling.
- Glass Mixing Bowl Set (Budget) - Just as non-reactive and budget-friendly.
- Instant-Read Meat Thermometer (Premium) - The fastest way to confirm the bison hit a safe internal temperature without cutting into it.
- ThermoPro Digital Thermometer (Budget) - Reliable, inexpensive, and plenty accurate for weeknight cooking.
Storage
These reheat beautifully, so don't be shy about making extra.
Store leftover stuffed zucchini boats in an airtight container in the refrigerator for up to 4 days. Reheat in a 350°F oven for 10-15 minutes, or microwave individual portions until warmed through - leftovers should reach 165°F when reheated. The bison filling itself is cooked to a safe 160°F internal temperature during browning, so reheating is just about getting it hot again, not about food safety. To freeze, wrap cooled zucchini boats individually and freeze up to 2 months. Thaw overnight in the fridge before reheating - zucchini turns watery if you try to bake it straight from frozen.
Top Tip
Salt the hollowed zucchini shells and let them sit cut-side up for about 10 minutes before stuffing, then blot them dry with a paper towel. Zucchini holds a lot of water, and skipping this step is the number one reason stuffed zucchini turns watery instead of tender. Go slow when you hollow them out, too - leave about a quarter-inch wall so the shell holds its shape in the oven instead of collapsing.
FAQ
Here's what people ask me most about this recipe.
Yes - either works. Ground beef gives you a richer, fattier bite, while ground turkey keeps it extra lean. Drain off any excess fat after browning if you swap in beef.
No. The zucchini bakes right alongside the filling, which is what keeps it tender instead of mushy. Just hollow it out enough that the walls aren't too thick to cook through in the bake time.
Yes. Make the filling up to 2 days ahead and store it in the fridge, then hollow the zucchini and stuff them right before baking. You can also fully assemble the unbaked boats a few hours ahead and refrigerate, covered, until you're ready to bake.
Salt the hollowed shells and let them drain for about 10 minutes before stuffing, then pat them dry. It pulls out extra moisture so the zucchini roasts instead of steams.

Originally developed as a stuffed pepper recipe - swap in 4 bell peppers, tops removed and seeded, for a heartier, sweeter version. Peppers are thicker-walled than zucchini, so add about 10 extra minutes to the covered bake time.
