I don't own a food dehydrator but I've been dying to make my own jerky for some time now. I've found that you can make it in the oven and it turns out pretty damn tasty. The problem with most store-bought jerky is that they often add sugar, soy, coloring and additives to the meat. Here's a pretty simple beef jerky recipe that you can make in the oven that avoids all of that nonsense.
1.5 lbs of London broil
1/4 cup coconut aminos
1 tbsp coconut oil
2 tsp garlic powder
1/2 tsp minced onion powder
1/4 tsp ginger
1/4 tsp turmeric
1/4 tsp oregano
1 pinch sea salt
Place the London broil in the freezer long enough for it start to harden a little but not long enough that it freezes (about 35-45 minutes). This will make the meat easier to slice.
Then take the London broil and turn it on its side length-wise and cut against the grain in slices. This can be a little challenging once the meat starts to thin out.
Place the slices into a bowl and set aside.
Add all of the other jerky seasoning ingredients into a small pot, bring to a quick boil and stir together. Pour the jerky seasoning over the meat and toss thoroughly. You can choose to let this sit overnight in the refrigerator and marinade or bake it right away. I baked it right away and the meat was flavorful and tender.
Set your oven to the lowest possible temperature setting, usually 150 degrees or Warm. Place the meat on metal racks or baking sheets (racks are preferable) and places those racks onto the racks in the oven. The 1.5 lbs of London took up two racks. Also, place an additional baking sheet at the very bottom of the oven to catch any drippings from the jerky. Close the oven door and let it bake for 6-8 hours. When the meat is done it will be a dark brownish color. The meat will bend and crack but not snap. If it snaps easily and is brittle, then it's over cooked.
Allow the jerky to cool and then store it in a ziploc bag or other airtight container.
