Soy-glazed beef eye fillet — whole 1.2kg piece, marinated overnight, browned + slow-roasted in a camp oven. Restaurant-grade beef from a campsite, served thick-sliced with Béarnaise sauce + roast vegetables. The dinner you make when the in-laws are camping with you.

Simple marinade, simple technique, exceptional result. The eye fillet does the work.

• 1 whole beef eye fillet (~1.2kg), trimmed of all sinew + fat
• 3 tbsp soy sauce (light or all-purpose)
• 2 cloves garlic, finely chopped
• 2 tbsp olive oil
• Cracked black pepper (lots — this is the main seasoning)

Optional add-ins: 1 tbsp grated ginger, 1 tsp sesame oil, 1 tbsp Mirin, splash of Worcestershire sauce.

To serve:

• Béarnaise sauce (premade or made from packet — Maille is a quality option)
• Roast vegetables (potatoes, carrots, asparagus)
• OR a simple green salad
• OR mashed potato
• OR creamy mushroom side

1. Trim the fillet. Remove ALL silverskin (the tough membrane) + any visible fat from the eye fillet. The silverskin shrinks during cooking + makes the fillet curl. Worth the 5 minutes with a sharp knife.

2. Make the marinade. In a freezer bag or large zip-lock, combine soy sauce, chopped garlic, olive oil + plenty of cracked pepper. Seal + shake to mix.

3. Marinate. Place the trimmed fillet in the bag with the marinade. Press out the air, seal tight. Massage the marinade around the fillet. Refrigerate AT LEAST 3 hours, ideally overnight (8-12 hours). Flip the bag halfway through to ensure even contact.

4. Pre-heat camp oven over hot coals — really hot. Build a strong coal bed beforehand.

5. Brown the fillet. Remove from marinade (don't discard the marinade — you can reduce it for a sauce). Pat the fillet briefly dry with paper towel.

Place in the hot camp oven, brown all sides — about 2-3 minutes per face. The whole fillet should have a deep mahogany sear all over.

6. Wrap + slow-roast. Wrap the browned fillet in heavy aluminium foil (double layer). Return to the camp oven. Reduce heat to medium (fewer coals).

7. Cook to your preferred doneness:

• Rare: 25 minutes (internal 50°C)
• Medium-rare: 28 minutes (internal 55°C)
• Medium: 32 minutes (internal 60°C)
• Medium-well: 35 minutes (internal 65°C)
• Well-done: 38-40 minutes (internal 70°C+)

8. Rest 10 minutes wrapped in foil before slicing. Critical step — juices redistribute, meat carves cleanly. Slice into 2cm thick slices.

9. Make a quick pan sauce (optional): pour the reserved marinade into a small saucepan with 100ml beef stock + a knob of butter. Reduce by half. Strain. Drizzle over sliced beef.

10. Plate up — 2-3 slices per person, dollop of Béarnaise on top, vegetables alongside, drizzle of pan sauce.

• Bring the fillet to room temp for 30-60 minutes before cooking. Fridge-cold = uneven cook
• Quality beef matters most. Eye fillet is expensive (~$50-80/kg) — buy the best you can. Look for marbling, deep red colour, no grey patches
• Meat thermometer is the secret to perfect — guessing doneness costs you. $20 for a basic instant-read thermometer pays back instantly
• Béarnaise alternatives: red wine jus, mushroom + cream sauce, blue cheese sauce, chimichurri (parsley + garlic + olive oil + chilli)
• Asian variations: add 1 tsp 5-spice + 1 tbsp Mirin to the marinade. Serve with stir-fried Asian greens + jasmine rice
• Without camp oven: works in a Dutch oven on low heat (gas stove), or sear on a hot BBQ + finish wrapped in foil on the cooler side. Or kitchen oven at 200°C for the slow-roast portion
• Leftovers are gold — cold sliced eye fillet on sourdough with horseradish + rocket. Lunch of the trip
• Cheaper cut alternative: a 1.5kg eye-of-rump or topside fillet works for half the cost. Marinate 24+ hours, cook the same way, slice thinner

The "make-the-trip" celebration dinner. Eye fillet + Béarnaise + roast vegetables from a campsite reads like a restaurant menu. With the right meat + a thermometer + 10 minutes of attention, the result is genuinely restaurant-grade.

Marinate at home, transport in the marinade bag, cook at the campsite — under an hour from coal-bed-ready to plates on table. Celebration dinner that doesn't ruin the holiday.
