As a result of increased water and salt removal, most diuretics also cause the body to lose potassium. This can be problematic because potassium is important for good health, especially if you have high blood pressure.
Place the dish of eggs in a larger dish and add enough water to reach about halfway up the sides. Place the eggs in the oven. Bake the eggs for 7 minutes for a runny yolk and for 8 to 9 minutes for a firm yolk. Carefully take the eggs out of the oven.
I cooked the eggs for 30 minutes. Meanwhile, I cooked a pot of hard-boiled eggs on the stovetop, so I'd have a comparison for the oven-cooked eggs. Once the 30 minutes were up, I removed the pan from the oven and used tongs to transfer the eggs to an ice bath to cool. I cooked another batch of eggs at 350 degrees, following the same procedure.
