Start by heating olive oil in a skillet over medium heat. Add zucchini and garlic, letting them soften for about 4–5 minutes until fragrant. Add the sausage, breaking it apart as it browns. Stir in salt, pepper, fennel, and Italian herbs for flavor. Pour in marinara and stock, then let it simmer for 5 minutes before setting it aside to cool slightly.
Preheat the oven to 400°F and spray your baking sheets with non-stick spray. Arrange the naan breads with space between them. Spread 2 tablespoons of ricotta over each naan to form a smooth, creamy base.
Spoon ⅓ to ½ cup of the sausage mixture onto each naan, spreading it evenly. Sprinkle generously with the shredded cheese blend, covering the sauce fully for that gooey lasagna-like finish.
Bake the pizzas for 11–13 minutes, rotating the trays halfway through. For those crisp, golden cheese edges, broil for one extra minute at the end.
Once baked, transfer the naan pizzas to a board. Scatter fresh parsley on top and cut them into wedges. Serve warm while the cheese is still bubbly and melty.
