Cooking Time

• Preparation: 15 minutes

• Resting: 10 minutes

• First Bake: 30 minutes

• Second Bake: 10 minutes

• Total Time: 1 hour 5 minutes

Ingredients

For the Base:

• 3 medium potatoes (about 600 g), peeled and grated

• 1 onion, finely chopped

• 1 carrot, grated

• 2 Tbsp olive oil (for sautéing)

• 2 large eggs

• 1 cup (200 ml) milk

• 80 g (⅔ cup) all-purpose flour

• Salt and freshly ground black pepper, to taste

• 2 Tbsp chopped green onions

• 2–3 Tbsp olive oil (for greasing the baking dish)

For the Topping:

• 2 medium tomatoes, thinly sliced

• 100 g (⅔ cup) grated cheese (cheddar, mozzarella, or your favorite blend)

• Salt, to taste

• Fresh parsley, chopped (for garnish)

Step-by-Step Cooking Directions

1. Prepare the Potatoes: Grate the potatoes into a bowl and cover with cold water. Let rest for 10 minutes to draw out excess starch. Drain and squeeze the potatoes in a clean kitchen towel until almost dry.

2. Sauté the Vegetables: Heat 2 Tbsp olive oil in a skillet over medium heat. Add chopped onion and grated carrot; sauté for 3–4 minutes until softened. Set aside to cool slightly.

3. Mix the Batter: In a large bowl, whisk together eggs, milk, flour, salt, and pepper until smooth. Fold in the drained potatoes, sautéed vegetables, and chopped green onions, stirring until all ingredients are evenly combined.

4. First Bake: Preheat your oven to 200 °C (400 °F). Grease a 20×20 cm (8×8 in) or similar baking dish with 2–3 Tbsp olive oil. Pour in the potato mixture, spreading it into an even layer. Bake for 30 minutes, until the surface is set and lightly golden.

5. Add Topping: Remove the dish from the oven. Arrange tomato slices in a single layer across the top, seasoning lightly with salt. Sprinkle the grated cheese evenly over the tomatoes.

6. Second Bake: Return the casserole to the oven for 10 minutes, or until the cheese is melted, bubbly, and beginning to brown.

7. Garnish & Serve: Let the casserole rest for 5 minutes, then scatter fresh parsley on top. Cut into portions and serve warm.

The Origins and Popularity of the Recipe

Casseroles date back to early 20th-century North America, where home cooks sought one-dish meals that were economical and feeding for large families. Potato-based bakes like the Scandinavian rårakor (potato pancakes) and the British bubble and squeak laid the groundwork. The modern egg-potato casserole evolved from breakfast strata and frittatas, marrying grated potatoes with a custard base. Today, its ease, adaptability, and all-in-one convenience make it a staple in church potlucks, family brunches, and comfort-food menus worldwide.

Common Mistakes to Avoid
