Configure APT to also cache all dependencies of a package?

I want to know if there is a way to configure APT to also download all the dependencies (as deep as the dependency spiral goes) of a package and cache them in /var/cache/apt/archives.

EDIT:
It seems that using apt instead of apt-get causes no caches to be downloaded. Can anybody confirm this please?

WHAT I TRIED:

I tried installing texlive-full with --install-recommends and saw that there are 155 packages to install but APT only cached texlive-full.deb.

Possible solutions:

1. Ask apt to install all those 155 packages which would cause them all to be cached. But this works only for dependencies that are one level deep.




2. Use apt-rdepends:
   
apt-get --print-uris --yes -d --reinstall install "$1" | grep "http://" | awk '{print$1}' | xargs -I'{}' echo {} | tee "$2"

   This spits out the url of all dependencies of given packages ($1) to a file ($2) which can then be input to wget.

Although 2 is the most feasible solution, it costs me bandwidth by having to download packages twice. And I don't want to create a local apt-mirror using apt-mirror.

This is likely the easiest method:

apt download $(apt-rdepends |grep -v "^ ")
