Preparation Phase & Tools to Use
Before diving into your cooking adventure, it’s essential to prepare your kitchen and gather the necessary tools. Start by preheating your oven to 375°F (190°C). This ensures a perfectly baked casserole. You’ll need a large pot for boiling the gnocchi and an oven-safe skillet for the final stage of the recipe.
To get the most out of your dish, consider using a non-stick skillet to sauté the gnocchi until they turn golden brown—this adds texture and flavor. Make sure to have a wooden spoon or spatula for stirring and mixing ingredients effectively. If you wish to enhance the toppings, a grater will come in handy for shredding your mozzarella cheese or grating Parmesan right before using it for a fresher flavor.

Ingredients
- 1 lb (450g) potato gnocchi
- 2 cups marinara sauce
- 1 ½ cups shredded mozzarella cheese
- ¼ cup grated Parmesan cheese
- 12–15 pepperoni slices
- ½ cup sliced black olives
- 1 tablespoon olive oil
- ½ teaspoon dried oregano
- ¼ teaspoon garlic powder
- ¼ teaspoon red pepper flakes (optional, for spice)
- Fresh basil leaves (for garnish)
Instructions
Step 1: Preheat & Prep
Start by preheating your oven to 375°F (190°C) to create the perfect conditions for baking your casserole. While your oven warms up, gather your ingredients so everything is at your fingertips when you need it. This helps streamline the cooking process.
Step 2: Cook the Gnocchi
In a large pot, bring salted water to a rolling boil. Carefully add the potato gnocchi and follow the package instructions for cooking time—usually just a few minutes until they float to the surface. Once cooked, drain them well in a colander and set aside, ensuring they are ready for the sautéing process.
Step 3: Sauté the Gnocchi
Heat 1 tablespoon of olive oil in an oven-safe skillet over medium heat. Add the cooked gnocchi to the hot skillet and sauté them for about 2 to 3 minutes. This step is crucial as it gives the gnocchi a lovely golden color and adds a bit of crunch. Keep an eye on them and stir occasionally to prevent sticking.
Step 4: Add Marinara & Cheese
Once the gnocchi are perfectly sautéed, pour in the 2 cups of marinara sauce, stirring gently to ensure all of the gnocchi are well-coated. This not only enhances the flavor but creates a delicious base. After that, generously sprinkle half of the mozzarella cheese and the entire amount of Parmesan cheese over the top, allowing for a rich, cheesy layer.
Step 5: Layer the Toppings
Now it’s time to get creative with your toppings! Arrange the pepperoni slices and sliced black olives in an even layer over the cheese. Top it off by sprinkling the rest of the mozzarella cheese evenly over the entire casserole, so it melts beautifully in the oven.
Step 6: Season & Bake
To elevate the flavors even further, sprinkle dried oregano, garlic powder, and red pepper flakes over the dish. This blend of seasoning not only adds depth but also a little kick if you choose to add the red pepper flakes. Carefully move the skillet to the preheated oven and bake for 15 to 20 minutes, or until the cheese is bubbly and golden brown, creating that irresistible melted cheese crust.
Step 7: Garnish & Serve
Once baked, remove the skillet from the oven using oven mitts—it’s going to be hot! Garnish your casserole with fresh basil leaves for a pop of color and flavor. Serve hot and watch everyone dive in eagerly!
