Ingredients

• 2 medium zucchini, sliced into ¼-inch thick rounds
• 1 cup low-fat cottage cheese
• ¾ cup reduced-fat shredded mozzarella cheese
• ¼ cup freshly grated Parmesan cheese
• ¼ cup plain nonfat Greek yogurt

• 1 large egg
• 2 cloves garlic, finely minced
• 1 tablespoon extra virgin olive oil
• 2 tablespoons fresh parsley, finely chopped
• 1 teaspoon Italian seasoning
• ½ teaspoon onion powder

• ½ teaspoon smoked paprika
• ¼ teaspoon black pepper
• ½ teaspoon sea salt
• ¼ teaspoon crushed red pepper flakes (optional)
• Cooking spray for the baking sheet

Ingredients Notes

• Zucchini
  Choose firm, medium-sized zucchini with smooth, glossy skin. Smaller zucchini contain fewer seeds and less moisture, helping the rounds bake evenly while maintaining their shape.
• Low-Fat Cottage Cheese
  Cottage cheese significantly increases the protein content while creating a creamy filling. Blending it slightly before mixing produces an even smoother texture if desired.
• Reduced-Fat Mozzarella Cheese
  Reduced-fat mozzarella melts beautifully while lowering saturated fat and calories. Freshly shredded cheese also melts more evenly than pre-packaged shredded cheese.
• Parmesan Cheese
  Parmesan adds a rich, nutty flavor that enhances the filling without requiring a large quantity. Freshly grated Parmesan provides the best taste and texture.
• Plain Nonfat Greek Yogurt
  Greek yogurt contributes extra protein while adding moisture and creaminess. It also replaces some of the higher-fat dairy ingredients without sacrificing flavor.

• Egg
  The egg acts as a natural binder, helping the cheese filling remain stable during baking and creating a creamy yet firm texture.
• Fresh Garlic
  Fresh garlic provides bold aromatic flavor that complements the zucchini and cheeses. Finely mincing the garlic ensures even distribution throughout the filling.
• Extra Virgin Olive Oil
  A light coating of olive oil helps the zucchini roast evenly while encouraging the cheese to brown beautifully in the oven.
• Fresh Parsley
  Fresh parsley adds vibrant color and a refreshing herbal finish that balances the richness of the cheeses.
• Italian Seasoning
  Italian seasoning provides a balanced blend of herbs that pairs perfectly with zucchini, garlic, and cheese while enhancing the overall flavor profile.
• Smoked Paprika
  Smoked paprika contributes a subtle smoky flavor and helps create an attractive golden finish after baking.
• Sea Salt and Black Pepper
  These seasonings enhance the natural flavors of every ingredient while keeping the recipe well balanced.

How to Make Diabetic High-Protein Cheesy Baked Zucchini Rounds

• Preheat the oven to 400°F (200°C). Line a large baking sheet with parchment paper or a silicone baking mat and lightly coat it with cooking spray to prevent sticking.
• Wash the zucchini thoroughly under cool running water and pat them completely dry using paper towels. Dry zucchini roast better and release less moisture during baking.
• Slice each zucchini into uniform ¼-inch thick rounds using a sharp chef’s knife. Keeping the slices even ensures consistent cooking and an attractive finished presentation.
• Arrange the zucchini slices in a single layer on the prepared baking sheet. Lightly brush both sides with olive oil and season with a small pinch of sea salt and black pepper.
• Bake the zucchini rounds for 8 to 10 minutes until they begin to soften slightly. Remove them from the oven and allow them to cool for several minutes while preparing the filling.

• In a medium mixing bowl, combine the low-fat cottage cheese, reduced-fat mozzarella, Parmesan cheese, Greek yogurt, egg, minced garlic, Italian seasoning, smoked paprika, onion powder, black pepper, and chopped parsley.
• Stir the mixture thoroughly until all ingredients are evenly combined and the filling becomes creamy and well blended.
• Spoon a generous tablespoon of the cheese mixture onto half of the partially baked zucchini slices. Spread it gently to cover most of the surface without allowing it to spill over the edges.
• Top each filled zucchini slice with another zucchini round to create a sandwich. Press gently so the filling spreads evenly while remaining inside the edges.
• Add another spoonful of the cheese mixture to the top of each zucchini sandwich, spreading it evenly to create a thick, cheesy layer that will become beautifully golden during baking.
• Arrange all assembled zucchini rounds back onto the baking sheet, leaving a small amount of space between each one so the hot air circulates evenly around them.
• Sprinkle a light layer of additional reduced-fat mozzarella and a small amount of Parmesan over each zucchini round for an extra crispy, golden finish.

• Return the assembled zucchini rounds to the preheated oven and bake for an additional 15 to 18 minutes. The cheese filling should become hot and creamy while the zucchini finishes cooking until tender but not mushy.
• During the final 2 to 3 minutes, switch the oven to the broil setting if desired. Watch carefully as the mozzarella and Parmesan develop a beautifully golden, lightly crisp crust without burning.
• Remove the baking sheet from the oven and allow the zucchini rounds to rest for about 5 minutes. This helps the cheese filling set slightly, making the rounds easier to transfer and serve.
• Sprinkle the tops with freshly chopped parsley for added freshness and color. If desired, finish with a light dusting of smoked paprika for extra visual appeal.
• Serve warm as a healthy appetizer, snack, light lunch, or vegetable side dish. Pair with grilled chicken, baked salmon, turkey breast, or a fresh salad for an even higher-protein meal.
• For meal prep, allow the zucchini rounds to cool completely before storing them in airtight containers. Reheat just before serving to restore their creamy texture and crisp cheesy topping.
