Ingredients

Gather your ingredients, and let’s get cooking! Here’s everything you need to create this scrumptious dish.
Full List of Ingredients
- 1 medium spaghetti squash
- 2 cups shredded sharp cheddar cheese
- 1 cup grated Parmesan cheese
- 1 cup heavy cream
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- Salt and pepper to taste
- 1 cup breadcrumbs (for topping)
- 2 tablespoons olive oil
- Fresh parsley for garnish (optional)
Step-by-Step Instructions
Step 1: Prepare the Spaghetti Squash
First things first, we need to prepare the star of the show—the spaghetti squash! Preheat your oven to 400°F (200°C). Carefully cut the spaghetti squash in half lengthwise, and scoop out the seeds using a spoon. Drizzle a little olive oil on the cut sides, and sprinkle with salt and pepper. Place the squash cut-side down on a baking sheet lined with parchment paper. Roast for about 30-40 minutes or until the flesh is tender and can be easily shredded with a fork. The aroma of the roasting squash fills the kitchen, and trust me, you’ll be eager to get started!
Step 2: Make the Cheese Mixture
While the squash is roasting, let’s whip up a creamy cheese mixture. In a mixing bowl, combine the heavy cream, garlic powder, onion powder, and a generous pinch of salt and pepper. Then, fold in 1 cup of shredded cheddar cheese and ½ cup of Parmesan cheese. This mixture will be the heart of your gratin, giving it that rich, cheesy goodness we all crave. Stir until well combined, and set it aside for now.
Step 3: Shred the Squash
Once the spaghetti squash is out of the oven and cooled slightly, grab a fork and start scraping the flesh. You’ll notice it separates into spaghetti-like strands—this is where the magic happens! Place the shredded squash into a large mixing bowl, and let it cool down a bit more. This step is crucial because it prevents the cheese mixture from clumping together when you combine everything later.
Step 4: Combine Everything
Now it’s time to combine our ingredients! Pour the creamy cheese mixture over the shredded squash, and mix gently until everything is evenly coated. This is where you can taste and adjust seasoning if needed. It should smell divine, with that creamy cheese mingling with the sweetness of the squash. If you’re feeling adventurous, feel free to add some sautéed onions or cooked bacon for extra flavor!
Step 5: Prepare the Topping
In a small bowl, mix the breadcrumbs with the remaining ½ cup of Parmesan cheese and 2 tablespoons of olive oil. This will create a crunchy topping that contrasts beautifully with the creamy squash below. The golden color of the breadcrumbs will add a delightful visual appeal, making it even more tempting to dig in!
Step 6: Assemble the Dish
Now that we have all our components ready, let’s assemble the gratin! Transfer the cheesy spaghetti squash mixture into a greased baking dish, spreading it out evenly. Then, sprinkle the breadcrumb mixture generously on top. This step not only adds flavor but also creates that satisfying crunch we all love in a gratin.
Step 7: Bake to Perfection
Pop the baking dish into the oven and let it bake for about 25-30 minutes. You’ll know it’s done when the top is golden brown and bubbly. Keep an eye on it towards the end, as ovens can vary, and you want to achieve that perfect crispy topping. As it bakes, your kitchen will fill with an irresistible aroma that will have everyone asking what’s for dinner!
Step 8: Garnish and Serve
Once it’s out of the oven, let it cool for a few minutes. Then, drizzle a bit of fresh parsley on top for a pop of color and freshness. Serve warm and watch as your family and friends dive into this deliciously cheesy dish. It’s truly a showstopper!
What to Serve with This Recipe
Suggested Pairings
While the Spaghetti Squash Au Gratin can stand alone, it pairs beautifully with a variety of side dishes. Consider serving it alongside:
- A fresh garden salad with a light vinaigrette
- Grilled chicken or shrimp for added protein
- Roasted vegetables to enhance the healthy vibe
- Crusty garlic bread for that classic comfort feel
Variations and Substitutions
Vegetarian Version
If you’re looking for a vegetarian option, simply skip the bacon or any meat additions. You can also add more veggies, like sautéed spinach, mushrooms, or bell peppers, for extra flavor and nutrition.
Different Cheeses
Feel free to experiment with different types of cheese. Gouda, mozzarella, or even a spicy pepper jack could elevate the flavor profile. Just keep in mind that stronger cheeses may alter the dish’s overall taste.
Gluten-Free Option
To make this dish gluten-free, substitute regular breadcrumbs with gluten-free breadcrumbs or crushed gluten-free crackers. The texture remains crunchy, and you won’t miss a beat!
Storage Instructions
Refrigeration
If you have leftovers (which is rare because it’s so delicious!), store them in an airtight container in the refrigerator. It will keep well for about 3-4 days. When reheating, add a splash of cream to bring back the creaminess.
Freezing
You can also freeze the assembled dish before baking. Just cover it tightly with plastic wrap and aluminum foil. When you’re ready to bake, thaw it in the fridge overnight and then bake as directed. This is perfect for meal prep!
