Ingredients
A handful of simple ingredients create this golden, cheesy sardine frittata.
1 can sardines in oil
3 large eggs
½ cup shredded mozzarella
1 tbsp chopped green herbs
Salt and black pepper
1 tbsp oil
Any firm cheese that melts well can replace mozzarella. Fresh parsley, chives, or green onion all work for the herbs. If you prefer milder fish, use canned tuna or mackerel instead of sardines. A splash of milk can be added to the eggs for a slightly softer texture.
Follow these eight simple steps for a perfect cheesy sardine frittata.
Step 1: Prepare the sardines
Open the can of sardines and drain most of the oil if desired. Place the sardines in a mixing bowl, keeping a few whole pieces aside for the top if you like.
Step 2: Add the eggs
Crack the eggs directly into the bowl with the sardines. The yolks and whites will help bind everything into a cohesive mixture.
Step 3: Season and mix
Add a pinch of salt, black pepper, and the chopped green herbs. Use a fork to gently break up the sardines and fully combine them with the eggs.
Step 4: Heat the pan
Warm the oil in a non-stick skillet over medium heat. Swirl the pan so the oil coats the bottom evenly before adding the mixture.
Step 5: Cook the base
Pour the egg and sardine mixture into the hot pan. Let it cook undisturbed until the edges start to set and the bottom turns lightly golden.
Step 6: Add whole sardines
Arrange any reserved whole sardines on top of the partially cooked frittata. This gives a nice visual and extra fish flavor in every slice.
Step 7: Top with cheese
Sprinkle the shredded mozzarella evenly over the surface. Continue cooking until the cheese begins to melt and the center is nearly set.
Step 8: Finish and serve
Slide the finished frittata onto a plate or carefully flip if desired. Let it rest one minute, then slice and serve while the cheese is still stretchy.
Tips & common mistakes
A few small habits help the frittata cook evenly and stay tender.
Use a non-stick pan for easy release every time
Keep the heat at medium to avoid burning the bottom

Here are answers to common questions about this sardine frittata.
Can I use fresh sardines instead of canned?
Yes, but you will need to clean and cook them first. Canned sardines are more convenient and already seasoned for this quick recipe.
How do I know when the frittata is fully cooked?
The edges should be set and lightly golden, and the center should no longer look wet. A gentle shake of the pan will show if the middle is still liquid.
Can I make this dairy-free?
Simply omit the cheese or use a plant-based melting cheese. The sardines and eggs still create a flavorful and satisfying frittata on their own.
How should I store leftovers?
Keep any leftover slices in an airtight container in the refrigerator for up to two days. Reheat gently in a skillet or microwave until warmed through.
