Description

Twice baked spaghetti squash is incredibly easy to make for an easy side or meal! It’s stuffed with garlic, four cheeses, artichokes, and spinach. 


Ingredients

Units Scale
  • 1 spaghetti squash, about 3 lbs.
  • 1 cup canned artichokes, drained + roughly chopped
  • 1 cup fresh baby spinach (lightly packed), chopped
  • 1/2 cup ricotta, part skim or whole milk
  • 1 cup shredded mozzarella cheese
  • 1/4 cup shredded Parmesan cheese
  • 2 Tbsp. mayonnaise
  • 3 garlic cloves, minced
  • 1 tsp. dried oregano
  • 1/4 cup fresh basil, cut into ribbons, plus more for garnish
  • 8 slices of deli Provolone cheese
  • Red pepper flakes, for serving
  • Olive oil
  • Kosher salt and fresh black pepper

Instructions

  1. Preheat the oven to 425 degrees F. Line a rimmed baking sheet with parchment paper.
  2. Using a sharp knife, cut the squash in half lengthwise. Scoop out the seeds and discard them.
  3. Rub the inside of the squash with a little olive oil, about 1-2 teaspoons, and sprinkle with salt and pepper. Place the squash cut side down on the baking sheet and bake for 30-40 minutes or until tender. Bake time will depend on the size of the squash. I used a small squash (about 3 lbs.) and it took about 35 minutes till it was done. When squash is done, cut sides should be golden and the interior easily pierced through with a fork. 
  4. Cool just enough to handle and using a fork, scrape the inside of the squash into long strands.
  5. In a bowl, combine artichokes, spinach, ricotta, mozzarella, parmesan, mayo, garlic, oregano, and basil. Season the mixture with salt and pepper, to taste.
  6. Top each squash halve with two slices of provolone cheese and an equal amount of the artichoke spinach mixture. Add two more slices of the provolone cheese over the artichoke mixture and bake for 10-15 minutes or until the cheese is melted and the filling is heated through. If desired, broil for 1-2 minutes for a golden top.
  7. Serve with a sprinkle of red pepper flakes and more basil.

Notes

  • Prep Tip: If you microwave the spaghetti squash for about 3 minutes it makes it easier to cut and scoop out the seeds. Just make sure to let the squash slightly cool before handling.
  • To Make Ahead: Prepare the recipe as written through step #6 but do not bake the squash.  Cover and refrigerate for up to 2 days. When ready to bake, uncover the squash, place on a baking sheet and bake as directed. After 15 minutes, check the squash to make sure it’s warmed through and if needed add additional bake time. 
  • To Store Leftovers: Scoop out the filling with the strands of spaghetti squash and transfer into a container with a lid. Discard the squash shell. Store leftovers for up to 2 days and reheat on the stovetop or microwave with little liquid.
