Wash and prepare the vegetables. Peel and chop the carrots and onion, and chop the celery. Cube the potatoes, rutebega and cut the garlic head in half horizontally.
Juice the lemon and set aside.
Place all the vegetables with the garlic, onion, salt-free seasoning, lemon juice and Italian seasoning into a large stock pot. Add the water.
Heat stove to high and let stock come to a boil, stirring often. Once boiling, reduce heat to a simmer (low to medium low) and cover.
Let simmer, stirring occasionally for 1 hour.
Once done, strain to remove veggies. Discard the bay leaves, onion and garlic. Discard or set aside vegetables (see notes). Let cool before pouring into freezer proof jars.
If using, refrigerate until use. If freezing let cool completely in the fridge for at least 4 hours or overnight before freezing. Leave 1-1/2 inch on top of each jar to allow for expansion.
