Lightly butter or oil the crock pot insert
Sprinkle in the minced onions and garlic
Separate or "crumble" the raw meat as you put it in the crockpot (if you don't separate it, it will cook in a huge block and be a pain to deal with)
Pour the beef broth over the top
Cover and cook on low for 6 to 8 hours (or overnight if you'd like to save some time and/or are prepping for freezer meals and meal planning)
When done cooking allow the meat to cool and pour off the grease/broth mixture.
Transfer 4 or 5 equal portions (you'll use the same number of freezer bags as you cooked of pounds of meat) to freezer safe canisters or bags, label, and freeze. Date with date cooked and/or a "use by" date. This make-ahead ground beef is freezer safe for 6 to 8 weeks.
