Total Time: 1 hour

Servings: 4–6

Ingredients

• 3 cups cooked spaghetti squash (about 1 medium squash)

• 2 large eggs

• 1 cup shredded mozzarella cheese

• ½ cup plain Greek yogurt

• 2 tablespoons minced garlic

• ½ teaspoon dried thyme

• Salt and pepper, to taste

• ½ cup grated Parmesan cheese

• Fresh thyme or parsley, for garnish (optional)

Instructions

Step 1: Prepare the Spaghetti Squash

1. Preheat your oven to 400°F (200°C).

2. Cut the spaghetti squash in half lengthwise. Scoop out the seeds.

3. Drizzle the cut sides with olive oil, sprinkle with a bit of salt and pepper, and place them cut-side down on a baking sheet.

4. Roast for 30–40 minutes, or until the flesh is tender and easily pulled into strands with a fork.

5. Let cool slightly, then scrape the inside of the squash with a fork to create “spaghetti” strands. Measure out 3 cups and set aside.

Tip: You can roast the squash ahead of time and store it in the fridge for up to 3 days.

Step 2: Mix the Filling

1. In a large mixing bowl, whisk together the eggs, Greek yogurt, and minced garlic until smooth.

2. Stir in the shredded mozzarella, dried thyme, salt, and pepper.

3. Add the 3 cups of spaghetti squash and mix everything together until fully combined.

Step 3: Assemble the Gratin

1. Grease a baking dish (9×9 inch or similar size) with butter or cooking spray.

2. Pour the squash mixture into the dish and spread evenly.

3. Sprinkle the grated Parmesan evenly over the top.

Step 4: Bake

1. Reduce oven temperature to 375°F (190°C).

2. Bake for 25–30 minutes, or until the top is bubbly and golden brown.

3. For a more browned top, broil on high for 2–3 minutes at the end — watch closely to avoid burning!
