Cooking roast beef on an Auspit is one of the easiest ways to get that proper fire cooked flavour without overcomplicating the process. With a little olive oil, your favourite seasoning, hot charcoal and enough time for the rotisserie to do its job, you can serve tender roast beef with crispy roasted potatoes straight from the fire.

This guide walks through the same method shown in our Auspit roast beef video, turning it into a clear step by step process you can follow at home, at camp or wherever you fire up your Auspit.

Quick Answer: How Long Does Roast Beef Take On An Auspit?

Roast beef on an Auspit generally takes around 2 to 3 hours over hot charcoal, depending on the size of the cut, heat level and how you like your beef cooked. For the potatoes, parboil them first, coat with oil and seasoning, then cook them in the Spitmate for around 45 minutes to 1 hour.

Why Roast Beef Works So Well On An Auspit

The Auspit is built for simple, effective rotisserie cooking over charcoal. As the beef slowly turns, the heat works evenly across the outside while the juices continue moving through the meat.

That gentle rotation helps create a beautiful outer crust while keeping the inside tender. The charcoal adds the flavour you just do not get from a standard oven, especially when the roast has enough time to slowly develop colour over the fire.

It is also a great cook for weekends, camping trips or relaxed backyard meals because once the beef is secured properly, the Auspit does most of the work for you.

Step-by-Step Instructions

1. Prepare The Roast Beef

Start by lightly coating the beef with olive oil. This helps the seasoning stick and encourages a nice crust as the beef cooks over the charcoal.

Once coated, season the roast generously with your favourite beef seasoning. Keep it simple if you like, or use a bolder BBQ rub if you want a stronger flavour.

2. Secure The Beef To The Auspit Skewer

Slide the beef onto the Auspit skewer and position it so the weight is balanced as evenly as possible.

Use the prongs to secure the roast firmly in place. This step matters because a loose roast can shift while spinning, which affects the cook and puts unnecessary strain on the setup.

Give the skewer a quick turn by hand before placing it over the charcoal to make sure everything feels steady.

3. Set Up Your Charcoal

Light your charcoal and let it build into a hot, steady coal bed. You want enough heat to roast the beef properly, but not so much flame that the outside burns before the inside cooks through.

Position the roast over the heat and let the Auspit slowly rotate the beef.

4. Roast For 2 To 3 Hours

Allow the beef to roast for around 2 to 3 hours over hot charcoal. The exact cooking time will depend on the size of the roast and how hot your charcoal is running.

Keep an eye on the fire and top up charcoal if needed. The goal is steady heat throughout the cook, not sudden bursts of flame.

5. Prepare The Potatoes

While the beef is cooking, parboil your potatoes until they just start to soften. Drain them, coat with oil and season well.

Place the potatoes inside the Spitmate and roast them over the charcoal for around 45 minutes to 1 hour. This gives them time to crisp up on the outside while staying soft in the middle.

The Spitmate is a great addition here because it lets you cook your side dish while the main roast continues spinning.

6. Rest & Slice The Beef

Once the roast beef is cooked to your liking, remove it from the skewer and let it rest before slicing. Resting helps keep the juices in the meat rather than losing them all on the board.

After resting, slice the beef across the grain and serve it with the roasted potatoes.

7. Serve & Enjoy

Serve the roast beef hot with the charcoal-roasted potatoes and your favourite sides. Gravy, mustard, horseradish, salad or roasted vegetables all work well.

This is simple, satisfying fire cooking that shows how easy roast beef can be on an Auspit.

Tips For Better Auspit Roast Beef

Balance the meat properly on the skewer before cooking so it rotates smoothly.
Use enough prongs to keep the roast secure from start to finish.
Keep your charcoal hot and steady rather than letting flames hit the meat directly.
Parboil potatoes first so they cook through properly in the Spitmate.
Always rest the beef before slicing for a better final result.
