The “Cheesiest” Spaghetti Squash Bowls

Thank you Brit + Co for the recipe!

Ingredients

  • 2 spaghetti squashes (sliced in half lengthwise and seeds scraped out)

  • ½ cup vegan butter 

  • ½ cup sliced shallot

  • ½ cup all-purpose flour

  • 3 + ½ cups cashew milk 

  • 4 oz. vegan smoked provolone 

  • 4 oz. vegan shredded mozzarella

  • ½ tsp kosher salt

  • Freshly cracked black pepper

  • 4 oz. vegan fresh mozzarella

  • ¼ cup panko bread crumbs

  • Crushed red pepper flakes

Instructions

  1. Preheat the oven to 350°F and line a sheet tray with parchment paper. 

  2. Place the squash cut-side down on a sheet tray and roast it in the oven for about 1 hour. 

  3. While the squash roasts, prepare the vegan cheese sauce. In a large saucepan over medium heat, sauté the shallots in the butter with a pinch of salt for about 5-7 minutes, stirring constantly. Add the flour and stir until combined. Continue to stir for about 3 minutes to cook the raw flavor out of the flour. Switch to a whisk and slowly incorporate the cashew milk into the mixture by pouring it in little by little. Whisk in the smoked provolone and the shredded mozzarella. Add the salt and pepper to the sauce and remove the mixture from the heat. 

  4. Carefully turn the squash halves over. Using a fork, scrape the flesh away from the sides to create spaghetti strands, making sure to leave about a ⅛-inch border of squash flesh. Place the strand in a medium stainless steel bowl. Keep the squash shells on the same sheet tray. 

  5. Mix about half of the cheese sauce mixture into the removed strands of squash. Once the squash strands are sufficiently sauced, refill the squash shells and dot the tops with the fresh mozzarella, about 1 tablespoon of panko bread crumbs per squash half, if using, and a light sprinkling of crushed red pepper flakes. 

  6. Place the squash back into the oven for about 1 hour. Switch the oven to high broil and brown the tops for about 3-5 minutes, keeping a close eye on them to ensure they don’t burn. 

  7. Remove from the oven and carefully transfer them to a plate. Serve hot.
