How to make Hamburger Helper faster (and better)
Instead of cooking everything in one skillet, cook the pasta in a separate pot of boiling water. For most varieties of HH it will only take 6 to 8 minutes, depending on the type of pasta included in the box. And since you'll no longer need all that extra liquid in the sauce to cook the pasta, you can reduce it down to just 1 cup of milk and 1/4 cup of water. The sauce will be done, and at the perfect thickness, just as soon as it starts boiling, which only takes a minute or two (no need to cover it with a lid). Then drain the pasta, mix it into the sauce/meat mixture and you're done.
If you cook it according to the instructions on the box, it calls for, for most varieties, 11 or 12 minutes, and then when you take the lid off it's still way too watery, so you'll have to boil it down under high heat, constantly stirring, for another 5 minutes or so. And by that time the pasta has been cooking for 16 or 17 minutes, and is way overdone/soggy.
The same idea works for Tuna Helper. 1 cup of milk and 1/4 cup of water is the right amount for all varieties of TH and HH that I've tried.
Also, this is a matter of preference, but 1 pound of ground beef is too much for the amount of sauce and pasta that's included in a box of Hamburger Helper. I use 1/2 pound instead. As for Tuna Helper, it always used to call for 1 can of tuna, but for the past 15 years or so, it's called for 2 cans. 1 can is still the right amount IMO, because tuna has a very strong flavor and 2 cans overpowers it.
