Twice-baked spaghetti squash with artichokes, spinach, four kinds of cheese, and plenty of garlic is an incredibly easy way to enjoy roasted spaghetti squash.

Serve it as a main dish alongside Chopped Greek Salad with Avocado or as a side. It’s cheesy, tender, and stuffed with so much goodness.

Roasted Spaghetti Squash

Roasted spaghetti squash is one of those secret vegetables that, when cooked, it has the texture and appearance of spaghetti strands. So you can do so much with it.

I personally love to roast it; stuff it with artichokes, spinach, garlic, and cheeses; and then roast it again.

I use a combination of ricotta, mozzarella, Parmesan, and provolone cheese. All this cheese, combined with plenty of garlic, is seriously a match made in heaven.

What is the Easiest Way to Cut Spaghetti Squash?

The easiest way to cut a spaghetti squash is to first nuke it. It slightly softens, making slicing a little easier. Simply place the spaghetti squash into a microwave and cook on high for 3 minutes.

You can place the squash directly into the microwave or on a plate. Remove from the microwave and cool just enough to handle. Using a very sharp knife, slice through from the top to bottom lengthwise. Use a spoon to scoop out the seeds and then prepare the squash as needed.

How to Cook Spaghetti Squash in Oven Cut in Half

Roasting spaghetti squash in the oven is incredibly easy to do. You’ll need one (3 pound) spaghetti squash, olive oil, salt, and pepper. Also, a rimmed baking sheet lined with parchment paper or aluminum foil.

  • Place the spaghetti squash halves cut-side up onto a flat surface, such as a cutting board or directly onto the prepared baking sheet.
  • Drizzle the insides of each squash half with a little olive oil and rub it all over the inside. Sprinkle the inside with salt and pepper lightly, then place them cut-side down on the baking sheet.
  • Bake for 30 to 40 minutes, until the cut sides are turning golden and the interiors easily shred with a fork. 
  • Remove from the oven and let it cool just enough to handle. After cooled, flip the spaghetti squash back to cut-side up and, using a fork, scrape the inside into spaghetti strands, leaving the strands inside the squash cavities.

How to Make Twice-Baked Spaghetti Squash

After you have roasted the spaghetti squash and shredded the insides into spaghetti strands, you’ll want to make the filling to stuff the squash and roast the second time around. 

  • Step 1: In a mixing bowl, combine artichokes, spinach, ricotta, mozzarella, parmesan, mayo, garlic, oregano, and basil. Season the mixture with salt and pepper, to taste.
  • Step 2: Top each roasted spaghetti squash half with two slices of provolone cheese and artichoke spinach mixture, dividing evenly among both halves. Top with two more slices of provolone cheese.
  • Step 3: Bake for 10 minutes or until heated through and the cheese has melted. 
  • Step 4: Serve sprinkled with red pepper flakes and fresh basil.

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 (3 lbs.) spaghetti squash
  • 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. mayo
  • 3 garlic cloves, minced
  • 1 tsp. oregano
  • 1/4 cup fresh basil, cut into ribbons, plus more for garnish
  • 8 slices of 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 little olive oil, 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.
  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 half 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 mixture and bake for 10 minutes or until the cheese is melted and heated through. Broil for 1-2 minutes or until golden.
  7. Serve with a sprinkle of red pepper flakes and more basil.

Notes

  1. 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 cool slightly before handling.
