Homemade Sugar-Free Beef Jerky with Macadamia Nuts

Why This Works for Intermittent Fasting

Beef jerky is one of the most portable, shelf-stable protein sources available — but commercial versions almost always contain hidden sugar. This version uses tamari and spices for deep savoury flavour with zero glucose spike. Paired with macadamia nuts (the highest-fat, lowest-carb nut available), this snack delivers a sustained fat-and-protein combination that supports a 16- to 20-hour fasting window without craving or hunger rebound.

Ingredients

For the beef jerky:

• 500g beef top round or sirloin, sliced 3–4mm thin against the grain
• 3 tbsp tamari (gluten-free soy sauce — no added sugar)
• 1 tsp garlic powder
• 1 tsp onion powder
• 1 tsp smoked paprika
• ½ tsp black pepper, freshly ground
• ½ tsp sea salt
• ¼ tsp cayenne pepper (optional, for heat)
• ½ tsp dried thyme

For serving:

• 180g raw macadamia nuts (30g per serving)

Instructions

1. Slice the beef. Place the beef in the freezer for 30–45 minutes until firm but not frozen — this makes clean, even slicing much easier. Slice 3–4mm thin, cutting against the grain for a tender chew.

2. Make the marinade. Whisk together tamari, garlic powder, onion powder, smoked paprika, black pepper, sea salt, cayenne (if using), and thyme in a bowl large enough to hold the beef.

3. Marinate. Add the beef slices to the marinade and toss to coat evenly. Cover and refrigerate for a minimum of 2 hours, or overnight for deeper flavour.

4. Preheat and prepare. Preheat your oven to 93°C (200°F). Line two large baking trays with wire racks. This keeps airflow around the meat and prevents steaming.

5. Lay out the beef. Remove the beef from the marinade, shaking off excess liquid. Lay slices in a single layer on the wire racks — they should not overlap.

6. Dry in the oven. Bake for 3–4 hours, rotating the trays halfway through. The jerky is ready when it is dry to the touch, bends without snapping, and tears cleanly. Thicker slices may need up to 4 hours.

7. Cool completely. Allow the jerky to cool on the racks for at least 20 minutes before storing. It will firm up further as it cools.

8. Serve. Portion into 6 servings of approximately 45g jerky and 30g macadamia nuts each. Store remaining jerky in an airtight container at room temperature for up to 2 weeks, or refrigerate for up to a month.

Fasting Compatibility

This snack fits naturally into any intermittent fasting protocol — 16:8, 18:6, or OMAD. It works particularly well as a pre-window snack eaten 15–20 minutes before the eating window closes, giving the body a slow-release protein and fat source that reduces hunger deep into the next fasting window. The near-zero carb content means no insulin spike, making it one of the cleanest ways to end your eating window.
