How to Make Creamy Spaghetti Squash Au Gratin
Step 1: Prepare Your Spaghetti Squash
Start by cooking your spaghetti squash. You can roast it in the oven or microwave it until tender. Pull apart the strands with a fork once it’s cool enough to handle. This step is crucial because perfectly cooked spaghetti squash provides that lovely texture you’ll want in every bite!
Step 2: Mix the Creamy Base
In a mixing bowl, combine your cooked spaghetti squash, eggs, mozzarella, Greek yogurt, minced garlic, thyme, salt, and pepper. Mix everything together until well combined. This mixture is where all that creamy goodness comes from! Make sure every strand of squash gets coated for maximum flavor.
Step 3: Transfer to Baking Dish
Pour your creamy mixture into a greased baking dish. Spread it out evenly so every bite bakes up beautifully golden brown on top. This step helps achieve that perfect au gratin finish that everyone loves!
Step 4: Top with Parmesan and Bake
Sprinkle grated parmesan generously over the top of your mixture before placing it in the oven at 350°F (175°C). Bake for about 30 minutes or until it’s bubbly and golden brown. Watching it bake is half the fun as your kitchen fills with delicious aromas!
Step 5: Serve & Enjoy!
Once baked, let it cool slightly before serving. Dig into this creamy delight with family and friends! You’ll find that each bite is satisfying and full of flavor, making this dish one you’ll cherish for years to come.

Pro Tips for Making Creamy Spaghetti Squash Au Gratin
Creating the perfect Creamy Spaghetti Squash Au Gratin is a breeze if you follow these helpful tips!
- Choose the right squash: Opt for a medium-sized spaghetti squash as it yields a good amount of strands without being too watery, ensuring a creamy texture in your dish.
- Thoroughly cook the squash: Make sure to cook the spaghetti squash until tender before pulling it apart. This step enhances its flavor and makes it easier to mix with the other ingredients.
- Mix well: When combining the eggs, yogurt, and cheeses, ensure everything is thoroughly mixed to create a smooth and creamy consistency. This will prevent any clumps and make every bite delightful.
- Adjust seasoning to taste: Don’t be shy about tasting your mixture before baking! Adding salt and pepper according to your preference will elevate the flavors and make the dish more enjoyable.
- Broil for extra crispiness: For that perfect golden-brown top, consider broiling the dish for a few minutes at the end of cooking. Just keep an eye on it to avoid burning!
