Can You Make Ham Loaf Using Canned Ham?

Yes you can use canned ham, but it may be more economical to buy a small piece of ham, depending on how much ham loaf you want to make. I usually buy at least a 3 pound or larger piece of ham, make it all up in small individual ham loaves, and freeze them. Here is the recipe I use, and we love it.
1 1/2 lb ground ham
1 lb ground pork
2 cups waverly cracker crumbs (same as butter crackers)
2 eggs, beaten
1 cup milk
1 lemon, juice and peel, grated ( many times I just use Real Lemon juice)

Mix together and shape into small individual loaves.
Glaze; 1 cup brown sugar,
1/2 cup water
1/2 cup vinegar
1 tsp dry mustard.
Heat sauce ingredients to dissolve sugar, pour over ham balls
Bake @325 for 1 1/2 hours. Spoon glaze over balls 2-3 times. ( the recipe says uncovered, but I do cover them when baking.)

I make these balls up, freeze, then wrap in saran wrap and put in one large bag in freezer. Take out as many as you need at a time, then make the glaze and pour over to bake. If I only make a few, I cut the glaze recipe in half.
