How to make Healthy Spaghetti Squash Au Gratin

Making Healthy Spaghetti Squash Au Gratin is simple and rewarding. You will enjoy every step of preparing this warm and cheesy dish. Below are the ingredients and directions to whisk you through the process smoothly.

Ingredients

1 medium spaghetti squash
1 cup shredded cheese (cheddar or your choice)
1/2 cup heavy cream or a low-carb alternative
1/4 cup grated Parmesan cheese
2 cloves garlic, minced
Salt and pepper to taste
Chopped parsley for garnish

Directions

Preheat the oven: Start by preheating your oven to 400°F (200°C). This ensures that it reaches the right temperature when you’re ready to bake your dish.
Prepare the squash: Cut the spaghetti squash in half lengthwise, then scoop out the seeds. This can be the trickiest part, but with a sharp knife and a spoon, it should be easy. Place the halves cut-side down on a baking sheet and roast them in the preheated oven for 30-40 minutes. You want them to be tender, so check them around the 30-minute mark.
Sauté garlic: While the squash bakes, heat a pan over medium heat. Add a bit of oil if you like, then sauté the minced garlic until fragrant, about 2-3 minutes. Be careful not to burn it!
Mix the sauce: In a mixing bowl, combine the heavy cream, shredded cheese, sautéed garlic, salt, and pepper. Stir everything together until well mixed and creamy.
Prepare the squash strands: Once the spaghetti squash is cooked, use a fork to scrape out the strands from the skin. This is where the fun begins! Toss the squash strands into the bowl with the cheese mixture, ensuring everything is well coated.
Combine and bake: Pour the cheesy spaghetti squash mix back into the squash shells or transfer it to a baking dish. Sprinkle the top with grated Parmesan cheese. Bake in the oven for another 10-15 minutes, or until it is bubbly and golden brown on top.
Garnish: Before serving, sprinkle some chopped parsley for a fresh touch and color.
