Start by preheating your oven to 400°F (200°C) and lining a baking sheet with parchment paper or lightly greasing it.
Split English muffins in half and place them cut-side up on the prepared baking sheet.
Spread pizza sauce or marinara sauce evenly over each English muffin half.
Top the sauce with shredded mozzarella cheese and your favorite pizza toppings such as pepperoni, sliced bell peppers, onions, olives, or mushrooms.
Bake the English muffin pizzas in the preheated oven for about 10-12 minutes or until the cheese is melted and bubbly, and the edges of the muffins are golden brown.
Remove the pizzas from the oven, let them cool slightly, and then enjoy your quick and delicious homemade English muffin pizzas.
