How to Make Garlic Butter Chicken Meatballs Stuffed in Spaghetti Squash Recipe

Roast the Spaghetti Squash

I start by cutting the squash in half and removing the seeds. Then I season it with salt, pepper, and a sprinkle of Parmesan. Roasting brings out the natural sweetness while softening it for stuffing.

Prepare the Cheese Sauce

While the squash roasts, I mix mozzarella, provolone, fontina, milk, chopped spinach, and sun-dried tomatoes. This creamy sauce is the heart of the dish, adding richness and texture.

Make the Chicken Meatballs

I combine ground chicken, Italian seasoning, Dijon, and Parmesan, then roll them into bite-sized meatballs. Using ground chicken keeps them tender, and the seasoning ensures each bite is flavorful.

Bake Everything Together

Once the squash has started roasting, I place the meatballs on the sheet pan. Everything bakes together until the meatballs are cooked and the squash is tender. This step infuses the flavors beautifully.

Add Garlic Butter and Finish

Finally, I chop the roasted garlic and mix it with butter and fresh herbs. I drizzle it over the meatballs and squash, then sprinkle extra cheese on top. A quick bake melts the cheese for the perfect finishing touch.

Additional Tips for Making This Recipe Better

Here are some tips from my own kitchen experiments:

I like to use a mix of fresh cheeses rather than pre-shredded for better melting
Roasting the garlic in its skin makes it sweeter and less harsh
Don’t overmix the meatballs or they can become dense
I scrape the squash with a fork while it’s hot to combine flavors well
Let the dish rest 5 minutes before serving to let the sauce set

How to Serve Garlic Butter Chicken Meatballs Stuffed in Spaghetti Squash

Serving is where the magic happens. I scoop the squash into bowls, nestle the meatballs on top, and drizzle any remaining garlic butter over everything. Fresh herbs or a sprinkle of Parmesan make it look gourmet. I love adding a side salad for color and crunch.

Make Ahead and Storage

Storing

I store leftovers in an airtight container in the fridge. They stay fresh for up to 3 days. It’s great for quick lunches or dinner.

Freezing

This dish freezes well. I let it cool completely, wrap tightly, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

I reheat in the oven at 350°F for 10–15 minutes. Microwaving works, but the oven keeps the squash texture intact and meatballs juicy.
