Step‑by‑Step Instructions for Sardine Margarita Bake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This sets the stage for the Sardine Margarita Bake, ensuring that the dish cooks evenly and the cheese melts to a bubbly perfection. While your oven warms up, gather your ingredients to streamline the cooking process.
Step 2: Prepare the Herbed Tomato Sauce
In a mixing bowl, combine tomato paste, oregano, garlic powder, salt, and pepper to create a vibrant herbed tomato sauce. Stir until smooth, ensuring all the seasonings are well incorporated. This flavorful sauce is the heart of your Sardine Margarita Bake, giving it rich and zesty notes that perfectly complement the fish.
Step 3: Rinse the Sardines
Open your cans of high-quality olive oil-packed sardines and rinse them lightly under cold water, if you prefer a milder taste. This step removes excess oil while preserving the delightful briny flavor. Gently pat them dry with a paper towel, readying them for layering in the next step.
Step 4: Layer the Sardines and Sauce
In the original sardine tin or a small baking dish, lay the sardines side by side, creating an even base. Pour the prepared herbed tomato sauce over the sardines, ensuring they’re generously coated. This layering ensures that each bite of the Sardine Margarita Bake is packed with flavor and moisture.
Step 5: Add the Mozzarella Topping
Evenly sprinkle shredded mozzarella cheese over the top of the sardine and sauce mixture. The cheese not only enhances the flavor but also forms a golden, gooey layer that makes the dish irresistible. Make sure to cover the sardines well for an optimal cheesy finish.
Step 6: Bake to Perfection
Carefully place your assembled dish into the preheated oven and bake for 15 minutes. You’ll know it’s done when the cheese is bubbly and golden brown, creating a beautiful contrast with the sauces below. Enjoy the delightful aroma filling your kitchen as the Sardine Margarita Bake cooks!
Step 7: Serving the Dish
Once baked, remove the dish from the oven and let it sit for a few minutes to cool slightly. Serve the Sardine Margarita Bake warm, ideally alongside crusty bread or crostini for dipping. This hearty Mediterranean appetizer is now ready to impress at your dining table!
