Just add another brush resource:
<mah:MetroWindow.Resources>
<SolidColorBrush x:Key="MahApps.Brushes.TopMenuItem.PressedFill"
Color="{StaticResource MahApps.Colors.Accent3}" />
<SolidColorBrush x:Key="MahApps.Brushes.MenuItem.SelectionFill" Color="{StaticResource MahApps.Colors.Accent3}" />
<Style BasedOn="{StaticResource MahApps.Styles.MenuItem}" TargetType="MenuItem" x:Key="MenuStyle">
<Setter Property="Background" Value="{StaticResource MahApps.Brushes.Accent}"/>
<Setter Property="Foreground" Value="{StaticResource MahApps.Brushes.IdealForeground}"/>
</Style>
</mah:MetroWindow.Resources>
