Ingredients Method

Ingredients

  

• 1 large spaghetti squash (about 3–4 pounds)
• 2 cups cooked, shredded chicken (rotisserie or poached)
• 1/2 cup buffalo sauce (mild, medium, or hot)
• 2 tablespoons unsalted butter (optional, for a richer sauce)
• 1/2 cup plain Greek yogurt or blended cottage cheese (for creaminess and extra protein)
• 1/2 cup shredded mozzarella (melty factor)
• 1/4 cup crumbled blue cheese or 1/4 cup shredded sharp cheddar (choose your vibe)
• 2 tablespoons ranch dressing or blue cheese dressing (for drizzling, optional)
• 2 green onions, thinly sliced
• 1 rib celery, finely diced (classic buffalo pairing, optional)
• 1 clove garlic, minced (optional)
• Salt and black pepper, to taste
• Olive oil or avocado oil, for roasting

Method

 

1. Preheat and prep the squash: Heat the oven to 400°F (205°C). Carefully slice the spaghetti squash in half lengthwise and scoop out the seeds. Brush the cut sides with oil and sprinkle with salt and pepper.
2. Roast until tender: Place squash halves cut side down on a baking sheet lined with parchment. Roast 35–45 minutes, until the flesh strands easily with a fork but isn’t mushy.
3. Shred the chicken: While the squash roasts, pull your cooked chicken into thin shreds. If using rotisserie, remove skin and bones first. Season lightly with salt and pepper.
4. Make the buffalo mix: In a skillet over low heat, warm the buffalo sauce and butter (if using). Stir in garlic for 30 seconds. Remove from heat and whisk in Greek yogurt or blended cottage cheese until smooth and creamy.
5. Combine with chicken: Add the shredded chicken to the sauce, tossing to coat. Stir in diced celery if you like extra crunch.
6. Shred the squash: When the squash is done, flip it cut side up and let it cool for a few minutes. Use a fork to gently pull the flesh into spaghetti-like strands, keeping the strands inside the shells.
7. Mix and fill: Add half of the mozzarella to the chicken mixture. Fold the sauce and chicken into the squash strands right inside each shell until combined and evenly distributed.
8. Top with cheese: Sprinkle the remaining mozzarella and the blue cheese or cheddar over the tops.
9. Back to the oven: Return the filled boats to the oven for 8–10 minutes, until the cheese is melted and bubbling at the edges. For extra color, broil 1–2 minutes—watch closely.
10. Finish and serve: Let rest 5 minutes. Drizzle with ranch or blue cheese dressing if desired, sprinkle with green onions, and add a few grinds of black pepper. Serve hot.

Health Benefits

• High protein for satiety: Chicken and Greek yogurt or cottage cheese deliver a solid protein boost to keep you full longer.
• Lower in refined carbs: Spaghetti squash provides volume and texture with fewer carbs than pasta.
• Micronutrient-rich: Squash offers fiber, vitamin C, manganese, and B vitamins.

  Green onions and celery add extra antioxidants and crunch.

• Customizable fats: Choose how rich you want it—use less butter and lean cheese for lighter macros, or add blue cheese for more flavor and calories.

Pitfalls to Watch Out For

• Overcooking the squash: If it’s too soft, it can turn watery. Roast until just tender, then let it rest before shredding.
• Curdled sauce: Don’t boil the yogurt mixture. Remove the pan from heat before stirring in yogurt or cottage cheese.
• Too salty: Buffalo sauce and cheese are already salty.

  Season the chicken lightly and taste as you go.

• Dry chicken: If your chicken is lean and dry, add a splash of chicken broth to the sauce for moisture.
• Heat level surprises: Sauces vary widely. Start with less buffalo sauce, taste, and adjust to your spice tolerance.

Recipe Variations

• Extra-high protein: Swap Greek yogurt for blended low-fat cottage cheese and add 2–3 tablespoons unflavored collagen or whey isolate to the sauce, whisking until smooth.
• Dairy-light: Skip the blue cheese and use a light sprinkle of mozzarella. Swap Greek yogurt for a dairy-free Greek-style yogurt if needed.
• Veggie-boosted: Stir in sautéed bell peppers, mushrooms, or spinach with the chicken for more volume and fiber.
• Ranch-forward: Mix 1 tablespoon dry ranch seasoning into the sauce and finish with a ranch drizzle.
• BBQ-buffalo mashup: Add 2 tablespoons BBQ sauce to the buffalo mixture for a sweeter, smoky twist.
• Spicier: Add crushed red pepper or a dash of cayenne.

  Top with pickled jalapeños.

• Air fryer finish: After filling, air fry at 375°F (190°C) for 5–7 minutes to brown the cheese quickly.

FAQ

Can I use ground chicken instead of shredded?

Yes. Brown 1.25 pounds of ground chicken with salt, pepper, and garlic, then mix with the buffalo-yogurt sauce. It’s faster and still high in protein.

What’s the best way to cook the chicken for shredding?

Poach chicken breasts in salted simmering water for 12–15 minutes, or use a rotisserie chicken for convenience.

Shred while warm for the best texture.

How can I make this less spicy?

Use a mild buffalo sauce, add the optional butter, and increase the yogurt slightly. A light ranch drizzle also cools the heat.

Can I prep this ahead?

Roast the squash and make the chicken mixture up to 2 days in advance. Store separately, then assemble and bake right before serving.

What cheeses melt best here?

Mozzarella melts smoothly, while cheddar adds sharpness.

A little blue cheese gives that classic buffalo vibe—use it sparingly for balance.

Is there a good dairy-free option?

Use dairy-free yogurt and a dairy-free cheese that melts well. Skip the blue cheese and use a neutral vegan ranch for topping.

How do I prevent watery boats?

Don’t over-roast the squash, let it cool before shredding, and drain excess liquid if needed. Mixing the sauce off heat also helps keep it creamy, not runny.
