Ok, here we go! Once a month cooking is a great way to plan ahead and make use of cheaper cuts of meat and weekly specials. Basically you spend a day cooking up big and chuck it all in the freezer. "Once a month" is a bit of a misnomer, because I really don't think there are too many people who literally cook once a month. Probably more that not, people do a big cook up once a week or once a fortnight. Whether you can actually cook only once a month depends on your level of organisation, experience and how big your freezer is. Also, some sites and books talk about freezing every meal for a month - including breakfast (things like pancakes, muffins, breads, etc) but its probably best to start with dinner.

Personally I have never done a full OAMC cook up because I don't have a chest freezer, but that's going to change V-E-R-Y soon

Basics

This site gives you a basic overview of the process. The idea is to plan, plan and plan again. If you need chopped onions for 5 recipies, don't chop the onions 5 times. Chop all you need at once.

Aussie Cooking OAMC

Here is a free OAMC guide: 30 day cafe guide

Ellen's Kitchen blog gives a comprehensive how-to list

Freezing food

Since OAMC relies heavily on the freezer, you need to know how to safely freeze food. The "Taste" website in Australia gives some good hints, but really any of the major Australian cooking sites will give you the basics. I really recommend you check one of these out before starting, just to make sure you have appropriate containers and have an idea of how to chill food properly so you get the best results.

Recipes

The only Australia site I have found (so far) which is any good is Planning with Kids (I love this site generally, though).

Unfortunately OAMC seems to be a real American thing - not that I have anything against Americans LOL but many of the recipes you will find on the web give measurements in pounds and ounces. (Plus a lot of the food doesn't seem to be to Australian "taste", IYKWIM? Really, you could use any old freezable recipe.

Here are some US websites with recipe ideas:

Real food starter recipes

A good book might be useful too. I have "Don't Panic--Dinner's In The Freezer: Great-Tasting Meals You Can Make Ahead" by Martinez and Howell but it is a US book and all the recipes need converting.

"The Frugal Mom's guide to Once a Month Cooking" by Candace Anderson seems to be popular too.

So there is a start - get planning
