How to Make Spaghetti Squash Pizza Casserole

Step 1: Preheat the Oven

First things first, preheat your oven to 375°F (190°C). Preheating is crucial because it ensures even cooking. If you skip this step, your casserole might end up unevenly baked. Trust me, you want that cheese to melt perfectly and bubble up beautifully!

Step 2: Prepare the Spaghetti Squash

Now, let’s tackle the spaghetti squash. Carefully cut it in half lengthwise using a sharp knife. This can be tricky, so take your time and use a sturdy cutting board. Once halved, scoop out the seeds with a spoon. You want to create a nice, clean bowl for your casserole. The strands of squash will mimic pasta, making this a fantastic low-carb pizza casserole. If you’re short on time, you can even buy pre-cooked spaghetti squash at the store!

Step 3: Layer the Ingredients

Next, it’s time to layer! Start by placing the spaghetti squash strands in a baking dish. Spread them out evenly to create a solid base. Pour your favorite pasta sauce over the squash, making sure to cover it well. This adds moisture and flavor. Now, sprinkle a generous amount of mozzarella cheese on top. If you’re feeling adventurous, add your favorite toppings like pepperoni or bell peppers. This keto spaghetti squash casserole is all about customization, so make it your own!

Step 4: Bake the Casserole

Finally, pop your casserole in the oven and bake for 25-30 minutes. Keep an eye on it! You’ll know it’s done when the cheese is bubbly and golden brown. Let it cool for a few minutes before serving. This healthy pizza casserole is sure to be a hit!
