Start by preheating your oven to 375°F (190°C). I always line my baking sheet with parchment paper so nothing sticks. Arrange the English muffin halves cut-side up and lightly brush them with olive oil for extra crispiness.
Place a slice of fresh mozzarella on each muffin half. Then layer a few tomato slices on top. Sprinkle with salt and black pepper to bring out the natural flavors of the ingredients.
Slide the baking sheet into the oven and bake for 12–15 minutes. I watch closely during the last few minutes to make sure the cheese is melted and slightly bubbly without browning too much.
Once out of the oven, immediately top each mini pizza with torn basil leaves. Drizzle lightly with balsamic glaze for a glossy, flavorful finish. Serve warm for the best taste.
