Keto Buffalo Chicken Stuffed Zucchini Boats – Spicy, Saucy, and Low-Carb
If you love bold flavor but want to keep things light and low-carb, these Keto Buffalo Chicken Stuffed Zucchini Boats hit the spot. They’re juicy, cheesy, and loaded with that classic buffalo kick—without the breading or extra carbs. The base is tender zucchini, which holds everything together without getting soggy.
It’s an easy weeknight dinner that feels fun and satisfying. Plus, you can prep most of it ahead, so getting it on the table is a breeze.
Ingredients
Method
- Prep the oven and pan. Heat the oven to 400°F (200°C). Line a baking sheet or shallow baking dish with parchment for easier cleanup.
- Hollow the zucchini. Slice each zucchini lengthwise. Use a spoon to scoop out the seeds and some flesh, leaving a 1/4-inch shell. Don’t toss the flesh—chop about 1/2 cup of it to add to the filling for extra moisture.
- Soften the shells. Brush zucchini boats with olive oil and a pinch of salt. Place cut-side up on the pan and bake for 8–10 minutes to soften slightly. This helps them bake evenly once stuffed.
- Mix the buffalo base. In a bowl, stir together cream cheese, sour cream, melted butter, buffalo sauce, garlic powder, onion powder, smoked paprika, pepper, and a pinch of salt. Mix until smooth and creamy.
- Add chicken and zucchini bits. Fold in the shredded chicken, the chopped zucchini flesh, and half the green onions. Taste and adjust heat with more buffalo sauce if you like it spicier.
- Stuff the boats. Spoon the buffalo chicken mixture evenly into each pre-baked zucchini shell, mounding slightly.
- Top with cheese. Sprinkle mozzarella (or Monterey Jack) over the stuffed zucchini. Add crumbled blue cheese if using.
- Bake. Return to the oven and bake for 12–15 minutes, until the zucchini is tender and the cheese is melted and lightly golden.
- Finish and serve. Let rest 5 minutes. Drizzle with ranch or blue cheese dressing, sprinkle with remaining green onions and parsley or celery leaves. Serve warm.
What Makes This Special
This recipe brings together three wins: high protein, low carbs, and big flavor. The zucchini softens in the oven and acts like a built-in bowl, so there’s no need for tortillas or buns.
The buffalo sauce gives you that addictive heat, while a creamy component balances it out. Topping it with melted cheese and a drizzle of ranch makes it taste like game-day food, but smarter.
It’s also flexible. You can use rotisserie chicken, leftover grilled chicken, or even canned chicken in a pinch.
And if you’re cooking for different spice tolerances, it’s easy to make one batch mild and another hot.

Keeping It Fresh
These hold up well for meal prep. Store leftovers in an airtight container in the fridge for up to 3–4 days.
Reheat in a 350°F (175°C) oven for 10–12 minutes, or microwave gently in 30-second bursts to avoid overcooking the zucchini.
If you want to freeze, it’s best to freeze the filling only. Zucchini releases water after freezing and can turn mushy. Portion the buffalo chicken mixture in freezer bags or containers for up to 2 months, then stuff fresh zucchini when you’re ready to bake.
Health Benefits
- Low in carbs: Zucchini is naturally low-carb and high in water, making it a great base for keto meals.
- High protein: Chicken boosts satiety and helps maintain muscle while cutting carbs.
- Healthy fats: Full-fat dairy and butter support ketosis and help absorb fat-soluble vitamins.
- Micronutrients: Zucchini offers vitamin C, potassium, and antioxidants, while green onions add flavor with minimal carbs.
- Customizable sodium and spice: You control the buffalo sauce and cheese amounts to fit your goals.
Common Mistakes to Avoid
- Scooping too thin: Leave some structure in the zucchini shell so it doesn’t collapse during baking.
- Skipping pre-bake: Raw zucchini can stay too firm while the filling overcooks.
A quick pre-bake keeps textures balanced.
- Overloading sauce: Too much buffalo sauce thins the filling and can make the boats watery. Start with the listed amount and adjust slowly.
- High heat rush: Blasting at a higher temp can split the dairy. Stick to the recommended temperature for a creamy finish.
- Forgetting to rest: A 5-minute rest helps the filling set and makes serving cleaner.
Recipe Variations
- Extra creamy: Add 1/4 cup shredded cheddar to the filling for richer texture.
- Mild version: Use a mild buffalo sauce or cut it with more sour cream.
Finish with a heavier ranch drizzle.
- Veggie boost: Stir in finely diced celery or bell pepper for crunch. Sauté briefly if you prefer softer veggies.
- Bacon upgrade: Crumble crisp bacon over the top after baking for smoky flavor.
- Dairy-light: Swap cream cheese for neufchâtel and use a lighter ranch. Keep an eye on carbs in store-bought dressings.
- Spice lovers: Add a pinch of cayenne or a dash of hot sauce to the filling and finish with sliced jalapeños.
- Different proteins: Use shredded turkey, leftover grilled thighs, or canned chicken for speed.
- Air fryer option: Pre-bake shells at 375°F (190°C) for 5–6 minutes, stuff, then air-fry 6–8 more minutes until cheese melts and edges brown.
FAQ
How do I keep the zucchini from getting watery?
Pre-bake the shells, don’t over-scoop, and avoid adding too much buffalo sauce.
You can also lightly salt the cut sides and let them sit for 10 minutes, then pat dry before baking to draw out extra moisture.
Can I make this ahead?
Yes. Mix the filling up to 2 days ahead and store it in the fridge. Stuff and bake when ready.
For best texture, don’t assemble the boats until just before baking.
What buffalo sauce should I use?
Choose a zero-sugar buffalo wing sauce to keep it keto. Frank’s-style sauces are classic, but any brand you like will work. Check the label for added sugars.
Is blue cheese necessary?
No.
Blue cheese adds that traditional buffalo flavor, but you can skip it or replace it with extra mozzarella, Monterey Jack, or a sprinkle of cheddar.
How spicy is this?
Moderate, as written. To go milder, reduce buffalo sauce and add more sour cream. To go hotter, add cayenne, hot sauce, or choose an extra-spicy wing sauce.
Can I use raw chicken?
Use cooked chicken for safety and speed.
If starting with raw chicken breasts or thighs, cook and shred them first—poaching, baking, or pressure-cooking are all good methods.
What can I serve with it?
Keep it simple with a crisp side salad, celery sticks with ranch, or roasted broccoli. If you’re not strict keto, a small serving of cauliflower rice works too.
How do I scale the recipe?
Double the filling for 6–8 zucchini. Use two sheet pans or bake in batches to avoid crowding, which can trap steam and soften the boats too much.
