Step-by-Step Instructions

Step 1: Prepare the Butternut Squash

  1. Preheat your oven to 375°F (190°C).
  2. Peel the butternut squashes, cut them in half lengthwise, and scoop out the seeds.
  3. Slice the squash into ¼-inch thick pieces.
  4. Toss the slices with olive oil, salt, and pepper, ensuring they are evenly coated.
  5. Arrange the slices in a single layer on a baking sheet and roast for 20–25 minutes, until tender but not fully cooked. Set aside to cool slightly.

Step 2: Make the Creamed Spinach

  1. Melt the butter in a large skillet over medium heat.
  2. Add the onion and sauté for about 5 minutes, until soft and translucent.
  3. Stir in the garlic and cook for another 1 minute.
  4. Gradually add the spinach, stirring until wilted. This may take a few batches depending on the size of your skillet.
  5. Pour in the heavy cream and bring the mixture to a gentle simmer. Let it cook for 5–7 minutes, stirring occasionally, until slightly thickened.
  6. Stir in ½ of the grated Parmesan cheese, the nutmeg, and season with salt and pepper. Remove from heat.

Step 3: Assemble the Gratin

  1. Increase the oven temperature to 400°F (200°C).
  2. Grease a large baking dish with cooking spray or butter.
  3. Layer half of the roasted butternut squash slices in the bottom of the dish.
  4. Spread the creamed spinach mixture evenly over the squash layer.
  5. Top with the remaining squash slices.
  6. Sprinkle the top layer with the remaining Parmesan cheese (or other desired toppings, like breadcrumbs or Gruyère).

Step 4: Bake the Gratin

  1. Cover the baking dish with aluminum foil and bake for 20 minutes.
  2. Remove the foil and continue baking for an additional 15–20 minutes, until the top is golden and bubbly.
  3. For a crispier finish, broil the gratin for 2–3 minutes. Keep a close eye to prevent burning.

Step 5: Rest and Serve

  1. Let the gratin rest for 5–10 minutes before slicing. This helps the layers set and ensures cleaner portions.
  2. Serve warm as a side dish alongside roasted poultry, grilled meats, or enjoy it as a vegetarian main course.

Pro Tips and Variations

  • Cheese Options: Try swapping Parmesan with Gruyère, sharp cheddar, or Pecorino Romano for a different flavor profile.
  • Herb Infusion: Add a sprig of thyme, sage, or rosemary to the cream for added depth.
  • Vegetable Add-Ins: Layer thinly sliced potatoes, sautéed mushrooms, or caramelized onions for extra complexity.
  • Advance Prep: Assemble the gratin a day ahead and refrigerate. Bring to room temperature before baking, or adjust the baking time if cooking directly from the fridge.

It complements roasted chicken, pork tenderloin, or grilled steaks beautifully. It’s also hearty enough to be a vegetarian main course.
