Ingredients
Method
- Prep the oven and pan: Preheat to 400°F (200°C). Lightly grease a large baking dish with 1 teaspoon olive oil.
- Hollow the zucchini: Trim ends and slice each zucchini lengthwise. Use a spoon to scoop out the centers, leaving a 1/4-inch border to form “boats.” Finely chop the scooped zucchini flesh and set aside.
- Season the boats: Brush cut sides with 1 tablespoon olive oil. Sprinkle with salt and pepper. Place in the baking dish, cut side up.
- Sauté aromatics: Heat the remaining olive oil in a skillet over medium. Add onion and cook 3–4 minutes until translucent. Stir in garlic and the chopped zucchini flesh; cook 2–3 minutes until most moisture evaporates.
- Make the filling: Reduce heat to low. Stir in shredded chicken, cream cheese, sour cream, Italian seasoning, smoked paprika, red pepper flakes, salt, and pepper. Mix until creamy and warmed through. If using marinara, fold it in now. Stir in half the Parmesan and half the mozzarella.
- Fill the boats: Spoon the chicken mixture into each zucchini, packing it evenly. Top with remaining mozzarella and Parmesan.
- Bake: Cover loosely with foil and bake 15 minutes. Remove foil and bake another 10–12 minutes until zucchini is tender and cheese is bubbly and golden at the edges.
- Finish and serve: Rest 5 minutes. Sprinkle with fresh parsley or basil. Taste and adjust seasoning if needed. Serve warm.
Why This Recipe Works
- Balanced texture: The zucchini softens in the oven but still holds its shape, while the filling stays rich and moist.
- Big flavor, simple steps: A few pantry staples—garlic, herbs, and cheese—turn basic chicken into a savory, satisfying filling.
- Low-carb and filling: High-protein chicken paired with fiber-rich zucchini keeps you full without the carb crash.
- Flexible: You can use rotisserie chicken, leftover grilled chicken, or even canned chicken in a pinch.
- Great for meal prep: They store well and reheat nicely, so make extra for easy lunches.

How to Make It
- Prep the oven and pan: Preheat to 400°F (200°C). Lightly grease a large baking dish with 1 teaspoon olive oil.
- Hollow the zucchini: Trim ends and slice each zucchini lengthwise.
Use a spoon to scoop out the centers, leaving a 1/4-inch border to form “boats.” Finely chop the scooped zucchini flesh and set aside.
- Season the boats: Brush cut sides with 1 tablespoon olive oil. Sprinkle with salt and pepper. Place in the baking dish, cut side up.
- Sauté aromatics: Heat the remaining olive oil in a skillet over medium.
Add onion and cook 3–4 minutes until translucent. Stir in garlic and the chopped zucchini flesh; cook 2–3 minutes until most moisture evaporates.
- Make the filling: Reduce heat to low. Stir in shredded chicken, cream cheese, sour cream, Italian seasoning, smoked paprika, red pepper flakes, salt, and pepper.
Mix until creamy and warmed through. If using marinara, fold it in now. Stir in half the Parmesan and half the mozzarella.
- Fill the boats: Spoon the chicken mixture into each zucchini, packing it evenly.
Top with remaining mozzarella and Parmesan.
- Bake: Cover loosely with foil and bake 15 minutes. Remove foil and bake another 10–12 minutes until zucchini is tender and cheese is bubbly and golden at the edges.
- Finish and serve: Rest 5 minutes. Sprinkle with fresh parsley or basil.
Taste and adjust seasoning if needed. Serve warm.
Keeping It Fresh
- Storage: Cool completely, then store in an airtight container in the fridge for up to 4 days.
- Reheating: For best texture, reheat in a 350°F (175°C) oven for 10–12 minutes. Microwave works in a pinch—cover and heat in 45-second bursts until hot.
- Freezing: Freeze after baking.
Wrap tightly and store up to 2 months. Thaw overnight in the fridge, then reheat in the oven until warmed through.
- Make-ahead: Assemble up to 24 hours in advance, cover, and refrigerate. Bake just before serving, adding 5–8 minutes if going straight from the fridge.
Benefits of This Recipe
- Keto-friendly macros: Low in carbs, high in protein and fat to support satiety and steady energy.
- Vegetable-forward: Zucchini adds hydration and fiber, helping balance the richness.
- One-pan convenience: Bake in a single dish for quick cleanup.
- Kid- and crowd-friendly: Mild flavors and cheesy topping win over picky eaters.
- Versatile base: Adjust spices and mix-ins to match what you have on hand.
What Not to Do
- Don’t skip salting the zucchini: A light sprinkle helps draw out moisture and keeps the boats from getting watery.
- Don’t overcook: Mushy zucchini collapses.
Bake just until tender when pierced with a fork.
- Don’t use low-fat dairy: It can turn grainy and lacks the richness that makes this satisfying.
- Don’t add too much sauce: A heavy hand with marinara can increase carbs and make the filling runny.
- Don’t forget to taste: Season the filling before stuffing so the flavors pop.
Variations You Can Try
- Buffalo chicken: Swap marinara for 2–3 tablespoons buffalo sauce. Add blue cheese crumbles and green onions.
- Spinach-artichoke: Stir in chopped spinach and artichoke hearts with extra Parmesan and garlic.
- Pesto chicken: Fold in 2 tablespoons basil pesto and top with fresh tomatoes after baking.
- Mushroom and thyme: Sauté mushrooms with the onion and garlic. Add fresh thyme and Gruyère.
- Bacon ranch: Mix in crumbled bacon and a teaspoon of ranch seasoning.
Finish with chives.
- Mexican-inspired: Season with cumin and chili powder; top with pepper jack and finish with cilantro and a squeeze of lime.
FAQ
Can I use raw chicken?
Yes, but cook it first. Sauté small pieces until fully cooked, then proceed with the recipe. Using pre-cooked or rotisserie chicken saves time and keeps the texture tender.
How do I keep the zucchini from getting soggy?
Scoop a sturdy 1/4-inch shell, lightly salt, and prebake covered for 10 minutes if your zucchini are extra watery.
Also, cook moisture out of the filling veggies before mixing.
Is there a dairy-free option?
Use a thick dairy-free cream cheese and a melty dairy-free cheese. Add a spoon of mayo or coconut cream for richness, and season a bit more to boost flavor.
What can I substitute for zucchini?
Try halved bell peppers, hollowed eggplant, or large portobello caps. Adjust bake time so the vegetable is tender but not mushy.
How many carbs are in this?
Exact macros vary by brands and sauce.
A typical serving (one stuffed half) lands around 6–9 net carbs when using low-sugar marinara or no sauce at all.
Can I make this without the tomato sauce?
Absolutely. Skip the marinara for ultra-low-carb and rely on the cream cheese, herbs, and spices for a rich, savory filling.
What cheese melts best here?
Mozzarella gives you the classic stretch, while provolone or Monterey Jack add a bit more flavor. Parmesan on top brings a crisp, golden finish.
How do I scale this for a crowd?
Double the filling and use a rimmed sheet pan.
Bake in batches or use two pans so the boats aren’t crowded, which helps them roast evenly.
