There are several post on meal planning, freezer meals, and cook a head meals....
For me while DH and I are empty nester, our family has grown a lot, so I still cook and stock the freezer with meals that I can use if they all show up and are hungry which is a lot... I divided up the portions a lot more into more meals for just DH and I...
I make around 100 to 200+ meatballs at a time, I wait until Ground chuck goes on sale, then buy the family size packages, which normally is even less than the standard around 1 pound packages sale price, my grocery store sometimes will have a sale on the family packages that is not in their AD so I always check to see... I make several different types but the 2 recipes I use most are for a Italian style and a Asian inspired... With the holiday approaching I am planning on making some this week... I have enough ground chuck for around 250 give or take a few meatballs, my family prefers the smaller ones so that what I go with. This go round I will make 150 Italian style and 100 Asian inspires.
Both recipes I created for what my family likes...
Italian meatballs- I whisk several eggs together round 3 to 5 depending on what size I have on hand, and how much meat I have, salt, pepper, what ever Italian seasoning I have and lately I have been using Herbs of the Provence in a lot of my cooking lately...minced garlic this is completely to taste - a couple of clove's, and some Worcestershire sauce - few good shakes this is depending on how much ground meat you have, don't go overboard...minced onions again this is to taste - I prefer sweet onions depending on size but normally a whole small one like the size of a lemon or lime.... I use a mixture of plain panko and Italian seasoned bread crumbs. I dump everything in and mix with my hands so I can tell the consistency of the meat - I keep a couple of paper towel next to me, in case I need to add more bread crumbs in... I use a small scoop and hand roll to keep them uniform in size... I bake at 350 until they are done around 30 minutes turning them once. I use a large pans with a baking racks so that the fats run into the bottom of the pan. I spray the racks lightly with some pam to prevent sticking. Cool completely on paper towels, then into freezer bags, don't forget to mark the bag with what's inside and date.
For the Asian inspired meatballs, I start with a couple of egg whisking them together, pepper, I skip the salt as the other components are quite salty again this is to your families taste. I use fresh basil- Thai basil if available, fresh ginger (galangal - Thai ginger) a little goes along was, I do tend to go heavier on the garlic (minced up few cloves), and a lot of chives and green onions, while I don't like lemongrass that much I will use it but again a little goes along way I have in the past use a bit of fresh squeezed lemon like maybe half a very small lemon, when I was out of lemongrass. A couple shakes of soy and teriyaki sauce... again a little goes along way. I sometimes supplement the soy and teriyaki sauce with like a marinade or even a salad dressing/marinades - Kens has Asian Sesame these went over really good when I used it.. It has ginger, soy & teriyaki so you don't need to add into the mixture if you are going this route, depending on how much meat you have I would start with a little and then you can add in more as you go... Have couple of container of Plain Panko on hand, these are wetter that more traditional meatballs.. I let the mixture sit in the frig for about a hour or two and you might have to remix again during the time in the frig... I use a small scoop for this as well, and hand roll, bake the same as the others 350 for around 30 minutes turning once. I use these for over rice with stir fry veggies, but I use them a lot for entertaining, I put them in the crock pot with a BBQ sauce, Hoisin and beer (Kirin or Sapporo) and apricot preservers or orange marmalade, last time I made these I made 300 and they were the first thing gone at the party...
* If you are cooking several sheet tray's at once additional cooking time is needed...
* I dumped everything in and only mix once, don't over mix it will make the meat tough.
* If the meatball seem to be really wet, you can roll them in plain bread crumbs or panko, to help dry them up, and it will create some texture on the outside.
