Drain and mash with melted Irish butter, half-and-half, and beaten egg until smooth and creamy. Stir in 1/4 cup of the grated Irish white cheddar cheese. Season with salt and pepper to taste.

Stir in the all-purpose flour to coat the vegetables. Gradually whisk in the vegetable broth and 1/2 cup half-and-half. Simmer for 6-8 minutes, whisking frequently, until the mixture is slightly thickened. Season to taste with salt and pepper.
