Ingredients:
6 medium potatoes
1 teaspoon salt (for boiling potatoes)
1 onion
2 cans (5 oz each) tuna in oil, drained
150 ml (5.3 fl oz) heavy cream (or whipping cream)
Zest of 1/2 lemon
2 cloves garlic, minced
Salt and black pepper, to taste
200 grams (7 oz) mozzarella cheese, shredded
Olive oil
A sprig of fresh rosemary (optional)
Instructions:
1. Boil the Potatoes:
Peel and cut the potatoes into evenly sized pieces.
Place them in a pot, cover with cold water, and add the teaspoon of salt.
Bring to a boil, then reduce heat and simmer until the potatoes are tender when pierced with a fork, about 15-20 minutes.
Drain the potatoes and set them aside to cool slightly.
2. Prepare the Onion and Tuna:
While the potatoes are cooking, slice the onion into thin half-rings.
In a separate bowl, drain the oil from the canned tuna and mash it with a fork.
3. Assemble the Casserole:
Preheat your oven to 200°C (390°F).
Grease a baking dish with olive oil.
4. Layer the Ingredients:
Start by creating a base layer with half of the cooked and sliced potatoes.
Top the potatoes with the sliced onions.
Spread the mashed tuna evenly over the onions.
Sprinkle half of the shredded mozzarella cheese over the tuna layer.
5. Make the Cream Sauce:
In a medium bowl, whisk together the heavy cream, lemon zest, and minced garlic. Season with salt and black pepper to taste.
6. Complete the Layers and Bake:
Pour the cream sauce evenly over the casserole.
Top with the remaining sliced potatoes and sprinkle with the rest of the shredded mozzarella cheese.
If using, add a sprig of fresh rosemary on top for a touch of fragrance (remove before serving).
7. Bake and Serve:
Bake the casserole for 25-30 minutes, or until the cheese is melted and bubbly, and the potatoes are tender throughout.
Remove from the oven and let cool slightly before serving.
More Info:
Feel free to experiment with different types of cheese. Gruyere, parmesan, or a cheddar and mozzarella blend would all work well in this recipe.
Chopped fresh herbs like parsley or dill can be added to the cream sauce for extra flavor.
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through.
