Description

This Creamy Spaghetti Squash Au Gratin is a delicious low-carb alternative to traditional au gratin dishes, featuring tender spaghetti squash baked in a rich, cheesy sauce made with eggs, Greek yogurt, mozzarella, and Parmesan. Seasoned with garlic and thyme, it offers a comforting, creamy texture with a golden crust, perfect as a nutritious side or vegetarian main dish.


Ingredients

Scale

Spaghetti Squash Mixture

  • 3 cups cooked spaghetti squash, pulled apart
  • 2 eggs
  • 1 cup shredded mozzarella cheese
  • 1/2 cup plain Greek yogurt
  • 2 tablespoons minced garlic
  • 1/2 teaspoon dried thyme
  • Salt, to taste
  • Pepper, to taste

Topping

  • 1/2 cup grated Parmesan cheese


Instructions

  1. Preheat and Prepare. Preheat your oven to 375°F (190°C). While the oven heats, ensure your spaghetti squash is cooked (either roasted or microwaved) and shredded into strands.
  2. Mix Ingredients. In a large bowl, combine the cooked spaghetti squash, eggs, shredded mozzarella, Greek yogurt, minced garlic, dried thyme, salt, and pepper. Stir well until all ingredients are fully incorporated into a creamy mixture.
  3. Transfer to Baking Dish. Lightly grease a baking dish, then spread the spaghetti squash mixture evenly in the dish to create a uniform layer.
  4. Add Parmesan Topping. Sprinkle the grated Parmesan evenly over the top of the squash mixture. This will help form a golden, savory crust during baking.
  5. Bake Until Golden. Place the baking dish in the preheated oven and bake for about 25-30 minutes, or until the top is bubbly and golden brown and the mixture is set when gently shaken.
  6. Cool and Serve. Remove from the oven and allow the dish to rest for 5 minutes before serving. This helps to set the creamy texture for easier slicing and serving.

Notes

  • To cook spaghetti squash, halve and roast it at 400°F for 40 minutes or microwave for 10-12 minutes until tender.
  • Use full-fat Greek yogurt for a creamier texture; low-fat options may produce a less rich dish.
  • Adjust garlic and thyme amounts to suit your taste preferences.
  • This dish reheats well and can be stored in the refrigerator for up to 3 days.
  • For a crispier top, broil for 2-3 minutes at the end of baking, watching carefully to prevent burning.
