Cover & marinate for 12-36 hours. Shake the bag a few times as it's marinating to make sure the beef is evenly coated.
Spread the meat in a single layer, shaking off any excess marinade, on the dehydrator trays.
Dry at 145F/62C for 4-6 hours, occasionally blotting off any fat droplets that appear on the surface. Test using a cooled piece. Properly dried jerky, when bent, should crack but not break.
Use tongs to transfer the jerky to a baking sheet so that they are not touching or overlapping one another. Heat them in a preheated 275°F oven for 10 minutes.
Cool, then package jerky in an air-tight container or vacuum seal (*see storage notes below). Store in a cool, dark & dry place.
Notes
Note 1: Some of our favorite cuts for beef jerky are top round, eye of round, top sirloin, and London broil.Note 2: Partially freezing the meat makes it easier to slice. Cut with the grain for chewier jerky & cut against the grain for tender but more brittle pieces.Storage: Properly dried and packaged jerky will keep for up to a month at room temperature in an airtight container, 3-6 months in an airtight container in the fridge, and up to a year if vacuum sealed and stored in the freezer.Source: OSU Extension Service/Pacific Northwest Extension (8/2020).
