How to Make Healthy Spaghetti Squash Au Gratin

This Healthy Spaghetti Squash Au Gratin is surprisingly simple to prepare, proving that healthy eating doesn’t have to sacrifice flavor or satisfaction. You’ll be amazed at how easily the tender spaghetti squash strands meld with a creamy, savory sauce, creating a dish that’s both comforting and incredibly good for you. The whole process, including roasting the squash, takes approximately 60 minutes, making it an ideal option for a busy weeknight.

Step-by-Step Instructions

  1. Prepare the Spaghetti Squash: Preheat your oven to 400°F (200°C). Carefully slice the spaghetti squash in half lengthwise. Scrape out the seeds and pulp from the center of each half using a spoon.
  2. Roast the Spaghetti Squash: Drizzle the cut sides of the squash halves with 1 tablespoon of olive oil and season with a pinch of salt and pepper. Place the squash halves cut-side down on a baking sheet lined with parchment paper. Roast for 40-50 minutes, or until the flesh is tender when pierced with a fork.
  3. Cook the Aromatics: While the squash is roasting, heat 1 tablespoon of olive oil in a large skillet or pot over medium heat. Add the finely chopped yellow onion and sauté until softened and translucent, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant, being careful not to burn it.
  4. Create the Creamy Sauce: Pour in the unsweetened almond milk. Whisk in the nutritional yeast, Dijon mustard, smoked paprika, and nutmeg. Bring the mixture to a gentle simmer, stirring frequently, until it begins to thicken slightly. This will take about 5-8 minutes. Season with salt and freshly ground black pepper to taste.
  5. Shred the Squash: Once the spaghetti squash is roasted and tender, remove it from the oven. Let it cool slightly until it’s comfortable to handle. Use a fork to scrape out the spaghetti-like strands into a bowl.
  6. Combine and Bake: Add the shredded spaghetti squash to the skillet with the creamy sauce. Stir gently to coat all the strands. If using Gruyère cheese, stir it in now until it begins to melt.
  7. Top and Bake: Transfer the mixture to a greased 8×8 inch baking dish or individual ramekins. In a small bowl, combine the panko breadcrumbs with a drizzle of olive oil and a pinch of salt and pepper. Sprinkle the breadcrumbs evenly over the top of the spaghetti squash mixture.
  8. Final Bake: Bake in the preheated oven at 400°F (200°C) for 15-20 minutes, or until the topping is golden brown and the sauce is bubbly.
  9. Serve: Let the Healthy Spaghetti Squash Au Gratin cool for a few minutes before garnishing with fresh chopped parsley. Serve hot.
