How Long to Dehydrate Beef Jerky at 145°F?

Beef jerky is a delicious and protein-packed snack that has been enjoyed for centuries. Making your own beef jerky at home is not only fun but also allows you to control the ingredients, flavors, and texture. One of the most common questions when making beef jerky is how long it takes to dehydrate at a temperature of 145°F.

Dehydrating Beef Jerky at 145°F

Dehydrating beef jerky at 145°F typically takes 4 to 6 hours. However, the exact drying time depends on several factors, including the thickness of the meat slices, the humidity level in your area, and the type of dehydrator or oven you are using. It’s important to check the jerky regularly to ensure it reaches the perfect level of dryness without over-drying or under-drying.

Factors That Affect Dehydration Time

Meat Thickness

• The thickness of the beef slices plays a big role in how long it takes to dehydrate. Thin slices (around 1/8 inch) dry faster, usually within 4 hours, while thicker slices (around 1/4 inch) may take closer to 6 hours.

Humidity Levels

• High humidity can slow down the drying process, while low humidity speeds it up. If you live in a humid climate, your jerky might take longer to dry.

Type of Dehydrator

• Some dehydrators have stronger airflow and better temperature control, leading to faster and more even drying. Others may take a bit longer, so always follow the manufacturer’s instructions.

Air Circulation

• Good airflow ensures even drying. If using an oven, keep the door slightly open to let moisture escape. In a dehydrator, make sure the trays are properly spaced for air to circulate around the jerky.

How to Know When Your Jerky Is Done

To check if your jerky is fully dehydrated:

• Bend Test: Take a piece and bend it slightly. It should be firm and leathery but not brittle. If it breaks in half, it is over-dried.
• Texture Check: The surface should feel dry and not sticky. If it still feels soft or moist, it needs more drying time.
• Use a Meat Thermometer: The internal temperature of the jerky should reach 160°F for safety. This ensures that all bacteria have been killed during the dehydration process.

Steps to Make Beef Jerky at 145°F

1. Prepare the Meat

• Choose a lean cut of beef like top round, bottom round, or sirloin.
• Trim off any fat because fat can make jerky spoil faster.
• Slice the meat into thin, even strips (1/8 to 1/4 inch thick).

2. Marinate the Meat

• Marinating enhances flavor and helps preserve the jerky.
• Common marinade ingredients include soy sauce, Worcestershire sauce, salt, pepper, garlic powder, onion powder, and honey.
• Let the meat marinate in the fridge for at least 6 to 24 hours for best flavor.

3. Arrange on Dehydrator Trays

• Lay the marinated beef strips in a single layer on the dehydrator trays.
• Make sure the pieces do not overlap so they dry evenly.

4. Set the Temperature to 145°F

• Turn on the dehydrator and set it to 145°F.
• Let the jerky dry for 4 to 6 hours, checking occasionally.

5. Check for Doneness

• After about 4 hours, start checking the jerky using the bend test and texture check.
• If it is still soft or sticky, continue drying for another 1 to 2 hours.
• Once fully dry, remove the jerky from the dehydrator and let it cool.

Storage Tips for Homemade Jerky

Proper storage ensures that your beef jerky stays fresh and safe to eat for a long time.

• Short-Term Storage: Store in an airtight container or zip-lock bag at room temperature for up to 2 weeks.
• Refrigeration: If you want to keep it fresh longer, store it in the fridge for up to 3 months.
• Freezing: For long-term storage, freeze jerky in a vacuum-sealed bag for up to 6 months.

Common Mistakes to Avoid

Cutting Meat Too Thick

• Thicker slices take longer to dry and may not dehydrate evenly. Aim for consistent thickness.

Not Using Enough Airflow

• If the air cannot circulate properly, the jerky may dry unevenly. Always space out the pieces.

Skipping the Temperature Check

• Always ensure the jerky reaches an internal temperature of 160°F to prevent bacteria growth.

Not Storing Properly

• Exposure to air and moisture can cause jerky to spoil faster. Use airtight containers.

Final Thoughts:

Dehydrating beef jerky at 145°F takes 4 to 6 hours, depending on the thickness of the slices, humidity levels, and airflow. Always check for proper dryness before storing. Making jerky at home is rewarding and allows you to create a healthy, protein-packed snack with your favorite seasonings. By following these steps, you can ensure your jerky turns out perfect every time!
