Ingredients
  

  • 4.0 large sweet onions
  • 1.0 cup shredded mozzarella cheese
  • 1.0 cup shredded cheddar cheese
  • 0.5 cup cream cheese
  • 0.25 cup grated Parmesan cheese
  • 2.0 cloves garlic
  • 1.0 tablespoon fresh thyme leaves
  • 1.0 tablespoon fresh parsley
  • 1.0 tablespoon olive oil
  • 1.0 teaspoon salt
  • 0.5 teaspoon black pepper
  • 0.25 teaspoon red pepper flakes
  • None leaves fresh basil for garnish

Instructions
 

  • Preheat your oven to 375°F (190°C).
  • Peel the onions and cut them into 1-inch thick slabs. Aim for 2-3 slabs per onion. You should get at least 8 onion slabs.
  • In a small bowl, mix the olive oil, salt, black pepper, and red pepper flakes if using. Brush both sides of each onion slab with the oil mixture and place them on a parchment-lined baking sheet.
  • In a medium bowl, combine the mozzarella, cheddar, cream cheese, Parmesan, and minced garlic. Add the thyme and parsley and mix until well blended.
  • Take a generous tablespoon of the cheese mixture and spread it on top of each onion slab. Press down lightly to help the cheese adhere.
  • Place the baking sheet in the preheated oven and bake for 25-30 minutes, or until the onions are tender and the cheese is bubbly and golden brown.
  • Once done, remove from the oven and let them cool slightly. Garnish with fresh basil leaves if desired. Serve warm.
