Kale and Spaghetti Squash Gratin Recipe

It’s fully sweater weather. Which I’m excited about, and not only because its arrival gave me an excuse to gift myself a couple of new cold-weather wardrobe items. I’m so ready for some food with heft. I’m talking about food that comforts – warms you from the inside out. Just like this gratin.

A delightful and comforting winter gratin.
Recipe Type: Gratin, Main
  • 1 small spaghetti squash, one that weighs ~2 lbs
  • 2 Tbsp butter
  • 2 Tbsp olive oil
  • 1 large onion, cut into ½ inch dice
  • 4 cups baby kale (or 1 large bunch kale of your choice)
  • 2 Tbsp flour
  • 1¼ cups half and half, maybe a bit more
  • ½ cup Parmigiano-Reggiano, freshly grated
  • Salt
  • Black pepper
  • Cayenne pepper
  1. Preheat the oven to 375ºF
  2. Cut the spaghetti squash in half, place each half, cut side down, on a parchment lined baking tray. Bake for 30 minutes.
  3. Remove from oven and allow to cool until you can handle it.
  4. Use a spoon to remove the seeds from the squash. Then, using a fork, scrape back and forth, creating long strands of 'spaghetti.'
  5. Once each half has been scraped clean, discard the skins and set the bowl of spaghetti squash aside.
  6. Gently warm the half and half in a small pot on a back burner, keeping an eye on it to be sure it doesn't boil over.
  7. In a wide pan, sauté the diced onions in the butter and oil over medium-low heat, until they begin to brown - around 15 minutes.
  8. Add the kale to the onions and season with salt, pepper and cayenne. Stir to incorporate.
  9. Once the kale has wilted, sprinkle with the flour and stir well - until the flour is transluscent and sticks to the veggies.
  10. Using a whisk, slowly incorporate the warm half and half, until it thickens to a sauce.
  11. Bring to a simmer, stir and if the sauce is gloppy and too thick, add a bit more half and half until it is thinned - it should coat the back of a spoon.
  12. Add half of the cheese, stir to melt it and turn off the heat.
  13. Add the squash to this mixture. Stir well to coat and transfer the entire mixture to a baking dish.
  14. Top with the remaining cheese and place under the broiler for 8-10 minutes, until the cheese is golden brown.
