You can use ActionView::Base to achieve this.

view = ActionView::Base.new(ActionController::Base.view_paths, {})
view.render(file: 'template.html.erb')

The ActionView::Base initialize takes:

1. A context, representing the template search paths
2. An assigns hash, providing the variables for the template

If you would like to include helpers, you can use class_eval to include them:

view.class_eval do
  include ApplicationHelper
  # any other custom helpers can be included here
end
