@TdeV, I don’t have a panini press nor an Anova oven but I routinely cook a whole package of bacon in my regular oven, arrange the cooked slices on paper towels, roll it up, pop in a ziplock bag and store in the freezer.
Slightly unrelated, I’ve been doing something similar with uncooked bacon: I lay the strips out on parchment paper, freeze that flat, then cover with another sheet of parchment, roll and store as above. This method is quite handy if I want just one strip (or even half a strip - cooking for one here) for a recipe where it’s mostly used for flavoring or as a garnish. I can easily use a scissors snip a frozen slice right into the pan in little strips, squares or even triangles and brown them up.
Of course, you can always just crumble a cooked slice but sometimes it’s nice to have it freshly cooked.
Edited to add that the kitchn uses an accordion fold so you don’t need to freeze flat. See here for that.
