Start by preheating your oven to 400°F (200°C). Place butter in an oven-safe dish and let it melt inside the oven for about 3–5 minutes. This step ensures the pancake doesn’t stick and gives it crispy edges.
In a mixing bowl, beat the eggs until smooth and slightly frothy. Add milk, flour, and salt, then whisk until you get a lump-free batter. Make sure not to overmix, as it can affect the texture.
Carefully remove the hot dish with melted butter from the oven. Immediately pour the batter into the hot pan, which helps the pancake puff up properly. The sizzling butter gives it a rich flavor.
Place the dish back into the oven and bake for about 25 minutes. You’ll notice the edges rising dramatically while the center sets. Bake until the pancake is golden brown and firm in the middle.
Remove from the oven and serve right away. The pancake will deflate slightly as it cools, which is completely normal. Add your favorite toppings and enjoy while warm.
