Instructions for Buffalo Chicken Spaghetti Squash Casserole
Making this delicious buffalo chicken spaghetti squash casserole is straightforward and perfect for beginners. Follow these simple steps for a satisfying meal.
- Prepare Oven and Dish: Preheat your oven to 400 degrees F (200 degrees C). Lightly spray a 9×13 inch baking dish with cooking spray. This prevents sticking and ensures easy cleanup.
- Cook Squash and Chicken: If your spaghetti squash is not already cooked, prepare it first. Halve the squash, scoop out seeds, brush with olive oil, season, and bake cut-side down until tender (about 30-40 minutes). Let it cool slightly, then scrape out the strands. Ensure your chicken is also cooked and shredded chicken.
- Whisk Wet Ingredients: In a large mixing bowl, combine the large egg, olive oil, onion powder, and garlic powder. Whisk them together until well blended. Add a few shakes of salt and pepper. If you are using plain chicken, you might need more seasoning. Rotisserie chicken usually has enough salt already.
- Add Sauces: Next, stir in the buffalo sauce and Greek yogurt (or your chosen substitute) into the egg mixture. Mix well until everything is smooth and evenly combined. This creates the creamy, tangy base for your buffalo chicken spaghetti squash casserole.
- Fold in Main Ingredients: Gently fold in the cooked spaghetti squash, shredded chicken, and ¼ cup of the shredded cheese with a wooden spoon or spatula. Ensure all ingredients are thoroughly coated with the sauce mixture. Be careful not to mash the squash too much.
- Transfer to Baking Dish: Carefully transfer the entire spaghetti squash mixture into your prepared 9×13 inch baking dish. Spread it out evenly using the back of your spoon.
- Top with Remaining Cheese: Sprinkle the remaining ¼ cup of shredded cheese evenly over the top of the casserole mixture. This will create a beautiful golden, bubbly crust.
- Bake the Casserole: Place the baking dish in the preheated oven. Bake for 20-25 minutes, or until the casserole is hot and bubbly throughout, and the cheese on top is melted and starting to turn golden brown.
- Rest and Serve: Once baked, remove the buffalo chicken spaghetti squash casserole from the oven. Let it cool and rest for about 10 minutes before serving. This allows the casserole to set slightly, making it easier to scoop and ensuring all the flavors meld together perfectly. Enjoy!
Pro Tips & Troubleshooting
- Cooking Spaghetti Squash: Bake the squash until it is just tender, not mushy. Overcooking leads to watery casserole.
- Prevent Watery Casserole: Ensure your spaghetti squash is properly drained after cooking. Squeeze out excess moisture for the best texture.
- Enhance Flavor: Taste your mixture before baking. Adjust salt, pepper, or buffalo sauce to your liking, especially with plain chicken.
- Meal Prep Efficiency: Cook your spaghetti squash and chicken a day or two in advance to save time on busy weeknights.
- Perfect Shredded Chicken: Use a stand mixer with the paddle attachment to effortlessly shred cooked chicken in seconds.
Serving, Storage & Variations
This buffalo chicken spaghetti squash casserole is incredibly versatile!
- Serving Suggestions: Serve this casserole alongside a crisp green salad with a light vinaigrette. A drizzle of ranch dressing or a dollop of blue cheese dressing on top is also a fantastic addition for authentic buffalo flavor.
- Storage: Store any leftover casserole in an airtight container in the refrigerator for 3-4 days. It reheats beautifully.
- Freezing: For longer storage, allow the cooled casserole to freeze in an airtight, freezer-safe container for up to 3 months.
- Reheating: Thaw frozen casserole in the refrigerator overnight. Reheat individual portions in the microwave, or cover and bake in the oven at 350°F (175°C) until warm through.
- Protein Boost: Easily add extra shredded chicken or more cheese for an even heartier meal.
- Different Proteins: Experiment with ground turkey, ground beef, or even canned tuna as alternatives to chicken.
- Make it Creamier: Substitute cream cheese for the Greek yogurt for an ultra-creamy texture and tangy flavor.
- Add Vegetables: Stir in finely diced bell peppers, sautéed onions, or steamed broccoli florets for extra nutrients and crunch.
- Non-Squash Base: If you prefer, swap the spaghetti squash for cooked regular pasta for a more traditional casserole feel.
