Chicken breast: Cooking and shredding the chicken yourself lets you control the texture and flavor; leftovers work great too.
Spaghetti squash: This is your low-carb noodle substitute and a fantastic vessel for all those buffalo flavors.
Celery: Adds a fresh crunch that contrasts nicely with the softness of the squash and chicken.
Green onions: Offer a subtle bite without overpowering the other ingredients.
Red bell pepper: Brings a touch of sweetness and vibrant color to the dish.
Buffalo sauce: This is the star spice, so pick one that suits your heat tolerance; homemade also works beautifully.
Ranch dressing: Creamy and cooling, it helps tone down the heat if you like a milder bite.
Blue cheese: Optional but highly recommended for that authentic tangy kick that complements buffalo flavors perfectly.

Extra Veggies: Throw in some sautéed mushrooms or spinach to add more color and nutrition.
Protein Swap: Try shredded rotisserie chicken for a super quick prep.

Step-by-Step: How I Make Buffalo Chicken Stuffed Spaghetti Squash Recipe

The image shows two halves of a yellow spaghetti squash filled with a mixed orange and white cheesy pasta layer speckled with small chunks of red bell pepper and green herbs. On top, there is a drizzle of white sauce and scattered crumbles of light blue cheese with specks of black pepper. A woman's hand is holding a silver fork lifting a cheesy bite with stringy melted cheese and bits of vegetables from one half. The squash rests on a slightly worn silver baking tray, all set on a white marbled surface. In the background, there is a blurred wooden bowl and a bottle. Photo taken with an iphone --ar 2:3 --v 7

Step 1: Roast the Spaghetti Squash Until Tender

I start by halving the squash and scooping out the seeds. To get perfectly tender strands, roast it face-down on a baking sheet at 400°F (200°C) for about 35 to 40 minutes. You’ll know it’s done when a fork slides easily through the flesh. This step locks in a lovely roasted flavor and makes shredding a breeze.

Step 2: Prepare the Buffalo Chicken Mixture

While the squash roasts, shred your cooked chicken breast with two forks—I find shredding by hand gives better texture than a food processor here. Then toss the chicken with buffalo sauce, sliced celery, green onions, and diced red bell pepper. If you want that creamy touch, stir in ranch dressing here. Don’t skip tasting as you go; it helps balance the heat and tang just right.

Step 3: Combine and Stuff

Once your squash is cool enough to handle, use a fork to fluff the strands and mix them gently into your buffalo chicken. Scoop that filling back into the squash shells—it makes for a beautiful presentation and keeps everything cozy while you finish baking.

Step 4: Bake to Melt and Marry Flavors

Pop the stuffed halves into the oven at 375°F (190°C) for about 10 minutes. This finishes melding the flavors and warms the dish through. If you’re using blue cheese, sprinkle it on top before this bake so it gets delightfully melty and slightly golden.

Top Tip

From my experience, handling the spaghetti squash with care and seasoning the chicken mixture well are game-changers for this recipe. Here are some insights I’ve picked up along the way to help you nail it every time.

Roasting Tip: Roast the squash face-down; it steams the flesh perfectly for that tender, noodle-like texture.
Shredding Chicken: Cool the chicken before shredding so it doesn’t get mushy and you maintain a nice texture in the final dish.
Sauce Balance: Taste the buffalo chicken mixture before stuffing—adding a splash of ranch if it’s too spicy really rounds out the flavors.
Don’t Overbake: The final bake is just to meld and warm up the filling; keep it short to avoid drying out the chicken.

How to Serve Buffalo Chicken Stuffed Spaghetti Squash Recipe

Buffalo Chicken Spaghetti Squash - Serving Suggestion

Garnishes

I love adding a sprinkle of extra blue cheese crumbs and chopped fresh parsley on top—that pop of color and flavor really elevates the dish. Sometimes a drizzle of ranch or a few celery sticks on the side completes the buffalo experience just right.

Side Dishes

This recipe pairs beautifully with simple sides like a crisp garden salad, roasted cauliflower, or even some crunchy carrot sticks to keep things light and fresh alongside the bold buffalo flavors.

Creative Ways to Present

For special get-togethers, I’ve hollowed out small spaghetti squash halves and baked the filling inside them individually — it looks lovely on a plate and makes serving easy. Adding a side of blue cheese or ranch dipping sauce in mini bowls looks great too and lets guests customize each bite.

Make Ahead and Storage

Storing Leftovers

Once cooled, I store leftovers in an airtight container in the fridge for up to 3 days. The flavors actually deepen overnight, making it an excellent next-day lunch or quick dinner.

Freezing

I sometimes freeze this dish by wrapping the stuffed squash halves tightly in foil and then placing them in a freezer-safe container. It freezes well for about 2 months. Just thaw in the fridge overnight before reheating.

Reheating

To reheat, I pop it in the oven at 350°F (175°C) for about 15 minutes or until warmed through. This method keeps the squash tender and prevents the chicken from drying out like microwaving sometimes does.

Frequently Asked Questions:

Can I use frozen chicken for this recipe?

Absolutely! Using cooked frozen chicken is a great shortcut. Just make sure it’s fully thawed before shredding and mixing with the buffalo sauce.

How spicy is the Buffalo Chicken Stuffed Spaghetti Squash Recipe?

The spice level depends on the buffalo sauce you use. If you prefer mild, pick a low-heat buffalo sauce or balance it with extra ranch dressing. You can always adjust the spice to suit your taste.

Can I make this recipe dairy-free?

Yes! Simply omit the blue cheese and use a dairy-free ranch dressing or avocado-based dressing to keep things creamy and buffalo-flavored without dairy.

What's the best way to cook spaghetti squash?

Roasting the spaghetti squash face down on a baking sheet at 400°F until tender is my go-to method—it’s simple and results in perfectly separated strands. You can also microwave it for a quicker option but roasting enhances flavor.
