How to Make Creamy Spaghetti Squash Au Gratin
Step 1: Prepare the Spaghetti Squash
Start by cooking your spaghetti squash until it’s tender. You can roast it in the oven, microwave it, or even use an Instant Pot. Once cooked, carefully pull apart the strands with a fork. This step is essential as it gives you those lovely spaghetti-like strands that make this dish so special!
Step 2: Mix the Ingredients
In a large bowl, combine the pulled spaghetti squash with eggs, mozzarella, Greek yogurt, minced garlic, thyme, salt, and pepper. Mixing these ingredients well is key to achieving that creamy consistency throughout the dish. Don’t be afraid to get your hands in there — it’s part of the fun!
Step 3: Add Cheese Topping
Transfer the mixture into a greased baking dish and sprinkle grated parmesan on top. The parmesan will create a beautiful golden crust while baking. It adds an extra layer of flavor that’s hard to resist.
Step 4: Bake and Enjoy!
Bake in a preheated oven at 350°F (175°C) for about 30 minutes until bubbly and golden. Keep an eye on it during the last few minutes to ensure it doesn’t over-brown. The aroma wafting through your kitchen will be heavenly! Let it cool slightly before serving so that each scoop holds together nicely.
And there you have it — a delicious Creamy Spaghetti Squash Au Gratin that’s sure to become a staple in your home! Enjoy every cheesy bite!
