Wash and dry the potatoes. Cut into French fry shapes or any other shape you like. Shake the raw French fries in a little vegetable oil or olive oil [and optional seasoning] Then bake on a jelly roll or cookie sheet. (sprayed with a little Pam) until just done.
Cool, leaving them on the sheet they were baked on, put them into your freezer, and freeze, making sure none are stuck together. Once frozen, put the potatoes into containers or bags and return to the freezer until you need them.
There is a little trick I do. I line the baking pan with heavy duty foil and spray and bake. I freeze and then bundle the freezer wraparound fries. and keep in freezer. When ready to reheat., I just open the foil and set on baking sheet. or put into oven directly without a tray.
When reheating in oven, make sure the oven is preheated first to 425 degrees F before putting in the fries, otherwise they defrost while oven is heating and become soggy. Bake until crisp, stirring potatoes once or twice to get all sides brown.
I like to make a variety of shapes:. steak size, shoestring, criss cross -- check out your frozen food section for ideas for shapes and for different flavors and seasonings. For jojos, dip in a texmex seasoned batter and bake or fry, then freeze. You can to this with sweet potatoes and zucchini. I love malted vinegar on mine, ketchup, tartar sauce, or buttermilk dressing. For a little more protein you can melt grated cheese on top of fries.
They make great snacks. I like to serve the heated fries, along with assorted dipping vegetables such as baby carrots and celery sticks and/ or chicken or fish nuggets. On the side is ranch or savory buttermilk dressing. The kids tdip away and have a ball. I also make a large serving platters this way and put in a variety of fried nuggets and every one helps themselves. It is a hit!
