Ingredients for Chicken Parmesan Spaghetti Squash

Gathering these ingredients is the first step to making a delicious spaghetti squash chicken parmesan. You’ll need:

1 medium spaghetti squash (about 2 to 3 lb) – this is our noodle base!
2 tablespoons olive oil, divided – helps roast the squash and adds richness
1 pound cooked boneless skinless chicken breasts, shredded or cubed – rotisserie chicken is a fantastic shortcut here
2 cups marinara sauce (homemade or store-bought) – choose a good quality sauce for the best flavor
2 cups shredded mozzarella cheese, divided – for that classic cheesy pull
1/2 cup grated Parmesan cheese, plus extra for sprinkling – adds a salty, nutty depth
1/4 cup panko breadcrumbs (optional for topping) – for a delightful crunchy finish
2 cloves garlic, minced – essential for aromatic flavor
1 teaspoon Italian seasoning – a blend of herbs that screams Italian comfort
Salt and freshly ground black pepper, to taste – to enhance all the other flavors
Fresh basil or parsley, chopped, for garnish – adds a pop of color and freshness

How to Make Chicken Parmesan Spaghetti Squash

Step 1: First things first, let’s get that oven preheated to 400°F (200°C). Slice your spaghetti squash right down the middle, then scoop out all those seeds. Give the cut sides a good drizzle of 1 tablespoon of olive oil, then season them with salt and pepper. Place the squash cut-side down on a baking sheet. Roasting it this way for about 35 to 45 minutes will make the flesh super tender and easy to shred with a fork.
Step 2: While your squash is doing its thing in the oven, it’s time to whip up the filling. In a medium bowl, combine the 1 pound of cooked shredded chicken with the 2 cups of marinara sauce. Stir in the 2 cloves of minced garlic, 1 teaspoon of Italian seasoning, and a little pinch of salt and pepper. Now, mix in 1/2 cup of the mozzarella and 1/4 cup of the Parmesan. This is where the magic starts to happen!
Step 3: Once the spaghetti squash is tender and cool enough to handle, use a fork to gently scrape out the strands. Try to get them into a large bowl, leaving the skins behind. Toss these beautiful squash strands with the remaining 1 tablespoon of olive oil and give them a taste. Adjust the salt and pepper if needed. This simple step makes the strands even more delicious.
Step 4: Now for the assembly! Grab a greased 9×13-inch baking dish. Layer about half of your spaghetti squash strands in the bottom. Then, spread that flavorful chicken-marinara mixture evenly over the squash. Top it off with the remaining spaghetti squash. Sprinkle the rest of the mozzarella and Parmesan cheese over everything. If you’re going for that extra crunch, mix the 1/4 cup of panko breadcrumbs with a tiny bit of olive oil and sprinkle them over the cheese. This makes for a truly delightful baked chicken parmesan spaghetti squash.
Step 5: Pop the dish back into the oven, but lower the temperature to 375°F (190°C). Bake for about 20 to 25 minutes, or until everything is heated through and that cheese is gloriously melted and bubbly. For an extra golden-brown topping, you can switch the oven to broil for the last 1 to 3 minutes, but keep a close eye on it so it doesn’t burn! This makes for a perfect baked chicken parmesan spaghetti squash. Let it rest for 5 minutes before garnishing with fresh basil or parsley.

Pro Tips for the Best Chicken Parmesan Spaghetti Squash

Here are a few tricks I’ve learned to make this dish absolutely perfect:

Don’t skip salting the squash: Before roasting, sprinkle salt on the cut sides of the spaghetti squash and let it sit for about 10 minutes. Dab away the moisture with a paper towel. This helps prevent a watery dish and concentrates the flavor.
Use good quality marinara: Since the sauce is a key flavor component, opt for a marinara you genuinely enjoy. A homemade sauce is fantastic, but a good store-bought one works wonders too.
Shredded vs. Cubed Chicken: Either works, but shredded chicken tends to distribute more evenly throughout the sauce, creating a more consistent bite in every forkful.
Watch the broiler closely: That final broil for golden cheese is amazing, but it can go from golden to burnt in seconds. Stay right by the oven and keep an eye on it!

What’s the secret to perfect Chicken Parmesan Spaghetti Squash?

The real secret to a perfect, healthy chicken parmesan spaghetti squash lies in properly preparing the squash – salting and roasting it cut-side down helps it cook evenly and prevents excess water. Also, don’t overcook the chicken; it should be tender and moist.

Can I make Chicken Parmesan Spaghetti Squash ahead of time?

Yes, you absolutely can! Assemble the entire casserole, cover it tightly with foil, and refrigerate it for up to 24 hours before baking. You might need to add a few extra minutes to the baking time if it’s cold.

How do I avoid common mistakes with Chicken Parmesan Spaghetti Squash?

A common pitfall is a watery casserole; this is usually due to not salting the squash beforehand. Also, resist the urge to overmix the ingredients, which can make the texture less appealing. Lastly, be mindful of the cooking times to ensure the squash is tender but not mushy.

Best Ways to Serve Chicken Parmesan Spaghetti Squash

This delicious dish is hearty enough to stand on its own, but serving it with a few simple sides really elevates the meal. For a truly satisfying experience, consider pairing it with a crisp Caesar salad or some crusty garlic bread to soak up any extra sauce. If you’re looking for more inspiration, think about serving it alongside roasted asparagus or a simple green bean almondine. It’s a versatile dish that fits perfectly into many meal plans, and it’s a wonderful alternative when you’re craving a spaghetti squash parmesan chicken casserole recipe but want something lighter.
