Let’s Get to Baking (No Fancy Titles Needed)

- Mix the filling: In a large bowl, mix squash strands, shredded chicken, softened cream cheese, garlic powder, onion powder, half the mozzarella, and a handful of grated Parmesan. Taste for salt—adjust if needed.
- Assemble and bake: Spoon the mixture into a greased 9×13 dish. Top with remaining mozzarella and Parmesan. Bake at 375°F for 20–25 minutes until bubbly and golden brown on top.
- Garnish and serve: Let it cool for a few minutes, then top with fresh basil ribbons. Slice, serve, and watch it disappear.
Little Pro Tricks

Over two decades of home-cooking later, here’s what I’ve learned about making this bake hit all the right notes:
Use parchment under your roasted squash halves—less mess, easier cleanup. Let the squash sit face-up for 5 minutes after roasting. It lets excess steam out, so you’re not baking a soggy mess. If you’re feeling spicy, add a pinch of crushed red pepper to the filling—gives it a grown-up kick that balances the cheese. And if you’ve got leftovers? It reheats beautifully in a skillet with a splash of broth or cream. Breakfast-for-dinner moment?
Serving It Up Right

This bake plays well with others. Pair it with a crisp arugula salad, roasted broccoli, or even a spoonful of sweet-savory meatballs. Got guests? Serve it as a side next to a big roast or grilled sausage. This one’s flexible like a Southern gal in cowboy boots looks delicate, handles heavy lifting.
