Step‑by‑Step Instructions for Spaghetti Squash Mac And Cheese
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) while you grease an 8×8 casserole dish with cooking spray or butter. This will ensure that your Spaghetti Squash Mac and Cheese releases easily once baked. The warm oven will help create that golden-brown crust for the topping that everybody loves!
Step 2: Cook the Spaghetti Squash
Next, cook the spaghetti squash using your preferred method—either roast it in the oven for about 40-50 minutes or steam it in an Instant Pot for about 8-10 minutes. Once cooked, allow it to cool slightly before cutting it open and scraping out the strands. Make sure to drain excess moisture to achieve the perfect texture.
Step 3: Mix the Cheese Sauce
In a large mixing bowl, combine the cooked spaghetti squash with sour cream, shredded cheddar cheese, sea salt, garlic powder, and ground black pepper. Stir until everything is well incorporated for a creamy and cheesy mixture. The vibrant colors will indicate it’s well-mixed and ready to be spread in the next step.
Step 4: Transfer to Casserole Dish
Evenly spread the creamy mixture into your prepared casserole dish. Use a spatula to smooth the top flat, ensuring even cooking. This will help your Spaghetti Squash Mac and Cheese cook uniformly and provide a lovely texture throughout, making each bite a delightful experience.
Step 5: Add the Crunchy Topping
Sprinkle bread crumbs or crushed pork rinds evenly over the top of the cheese mixture. This topping will form a delicious crust while baking. For added crispiness, consider using panko breadcrumbs here, as they tend to give an extra crunch that perfectly complements the creamy filling.
Step 6: Bake to Perfection
Bake your dish in the preheated oven for 30-35 minutes. You’ll know it’s done when it’s heated through, bubbling along the edges, and has formed a lovely golden-brown crust on top. Keep an eye on it, as ovens may vary, and you want to avoid over-baking.
Step 7: Broil for Extra Crispiness
For that glorious, extra crispy topping, turn on the broiler for an additional 2-3 minutes after baking, watching closely to avoid burning. This step brings the finishing touch to your Spaghetti Squash Mac and Cheese, making it irresistible with a delightful crunch that contrasts beautifully with the creamy filling.

Spaghetti Squash Mac and Cheese Recipe FAQs
How do I choose the best spaghetti squash?
Absolutely! When selecting spaghetti squash, look for one that is firm and has a smooth, golden-yellow skin. Avoid any with dark spots or soft areas, as these may indicate overripeness. A typical spaghetti squash should feel heavy for its size and have a vibrant color to ensure optimal flavor and texture.
How should I store leftovers of spaghetti squash mac and cheese?
You’ll want to keep it fresh! Store your Spaghetti Squash Mac and Cheese in an airtight container in the refrigerator for up to 3-4 days. This helps maintain the creamy consistency and flavor. Make sure it’s completely cooled before sealing to prevent condensation from making it soggy.

Yes, you can freeze it for future meals! To do this, allow the dish to cool completely, then transfer it into a freezer-safe container. It can be frozen for up to 2 months. When you’re ready to enjoy it, thaw it overnight in the refrigerator, then reheat in the oven at 350°F (175°C) until heated through. For best results, add a splash of milk when reheating to restore some creaminess.
What should I do if my dish turns out too watery?
If your Spaghetti Squash Mac and Cheese ends up watery, it’s usually due to excess moisture in the spaghetti squash. To avoid this, make sure to thoroughly drain the squash after cooking.

Is there a way to make this recipe vegetarian-friendly?
