Preheat your oven to 400°F (200°C). This ensures that the bagels will bake evenly and become crispy.

Slice the bagels in half horizontally. This will create a base for your toppings.

Place the bagel halves on a baking sheet lined with parchment paper. This prevents sticking and makes cleanup easier.

Spread about 2 tablespoons of marinara sauce on each bagel half. This will be the base layer of flavor.

Sprinkle shredded mozzarella cheese generously over the sauce. This will melt and create a delicious cheesy topping.

Add pepperoni slices on top of the cheese. Feel free to customize with other toppings like bell peppers or mushrooms.

Sprinkle dried oregano over the top for added flavor. This gives a classic pizza taste.

Drizzle a little olive oil over the assembled bagels to help them brown and add richness.

Place the baking sheet in the preheated oven and bake for 12-15 minutes, or until the cheese is melted and bubbly, and the bagels are golden brown.

Remove from the oven and let cool for a few minutes before serving. This helps the cheese set slightly and makes them easier to handle.
