Features & Benefits of the Leonardo 3-Burner

Cast Iron Grates for Superior Grilling Results

The cast iron grill grates form the beating heart of this Boretti barbecue. Cast iron heats evenly and retains heat excellently, which creates those characteristic grill marks and optimal Maillard reaction on your meat. Unlike cheaper enamelled or chrome-plated grates, cast iron develops a natural non-stick coating (seasoning) over time that only gets better. The material is moreover practically indestructible and will last a lifetime with proper maintenance.

Three Main Burners plus Side Burner for Maximum Flexibility

The three independently adjustable gas burners give you complete control over temperature zones. For example, you can set one side to high temperature for searing steaks, whilst the other side at lower power is suitable for poultry or fish. The extra side burner on the side of the barbecue has its own cooking grate where pots and pans fit. This way you can prepare rice, vegetables or casseroles whilst the main course is on the grill – ideal for complete outdoor meals.

Robust Stainless Steel and Aluminium Frame with Wheels

The Leonardo's frame combines stainless steel with aluminium for durable construction that withstands all weather conditions. The barbecue is easy to move thanks to sturdy wheels, allowing you to effortlessly manoeuvre it to your desired garden location or store it temporarily. The two spacious side tables provide ample work space for chopping boards, plates and grilling tools, whilst the three tool hooks ensure your tongs, fork and spatula are always within reach.

Suitable for Direct and Indirect Grilling

Thanks to the three independent burners, with the Leonardo you can grill both directly and indirectly. With direct heat you prepare thin cuts of meat, burgers, sausages and vegetables quickly at high temperature. For indirect grilling, you turn off the middle burner and use the two outer burners, creating an oven effect. This method is perfect for large cuts of meat, spare ribs, whole chickens or even pizzas. The flexibility makes this barbecue suitable for any grilling recipe.

Uses

Perfect Steaks with Restaurant-Quality Grill Marks

The cast iron grates reach high temperatures and retain heat excellently, which is essential for perfectly seared steaks. Preheat the barbecue to maximum power, place your entrecote or ribeye on the hottest part of the grate and turn it a quarter turn for diamond-shaped grill marks. The natural seasoning of the cast iron prevents sticking and enhances flavour. With the large grilling surface you can prepare eight to ten steaks simultaneously – perfect for a barbecue evening with friends.

Healthy Summer Meals with Fish and Vegetables

The side burner opens up a world of possibilities for complete, healthy meals. Grill salmon, sea bream or sea bass on the main grates whilst preparing rice, potatoes or a Mediterranean vegetable sauce on the side burner. The cast iron grates are also ideal for vegetables: peppers, courgettes, aubergines and asparagus get beautiful grill marks and retain their bite. Thanks to the two temperature zones you can place delicate ingredients on the cooler side and robust items on high heat.

Slow Cooking and Smoking for Advanced Users

For slow-cooked barbecue enthusiasts, the Leonardo with its indirect grilling options delivers excellent results. Prepare pulled pork, beef brisket or spare ribs by using only the outer burners and placing the meat in the middle. Add a smoke box with wood chips to one of the active burners for extra smoky flavour. The stable temperature control of the gas burners makes it easier than with a charcoal barbecue to maintain a constant temperature of 110-130°C for hours on end.

Assembly & Use

The Boretti Leonardo is delivered in robust packaging with clear assembly instructions. Assembly takes approximately one to one and a half hours and is straightforward for two people using standard tools. Start by assembling the frame and wheels, then attach the housing and install the gas burners according to the instructions. Thoroughly check all gas connections with soapy water to exclude leaks before lighting the barbecue for the first time. Take your time with careful assembly – this is the foundation for years of grilling enjoyment.

Before preparing your first meal, it is important to season the cast iron grates. Preheat the barbecue to maximum power for approximately 15 minutes to burn off any manufacturing residues. Let the grates cool, brush them clean and rub them in with a thin layer of vegetable oil. Heat the barbecue again for 10 minutes – this process establishes the foundation for the natural non-stick coating. Repeat this seasoning process after every thorough cleaning and your grates will remain in top condition for decades.

For daily maintenance it is sufficient to preheat the grates and clean them with a stainless steel grill brush. After finishing your grilling season, thoroughly clean the barbecue: remove the grates, clean the interior of the hood and the grease catch pan, and check the burners for blockages. Preferably store the barbecue under cover or use a suitable protective cover. The ten-year warranty from Boretti gives you the assurance that this investment will last for years, provided you maintain the barbecue properly.

Frequently Asked Questions

Which gas bottles can I use with the Leonardo?

The Boretti Leonardo works standard with propane or butane gas bottles, with a 10 kg bottle being most common. You connect the bottle via the supplied pressure regulator and gas hose. Ensure the pressure regulator is suitable for Dutch gas bottles (30 mbar for propane). A full 10 kg gas bottle is sufficient for approximately 20 to 25 hours of grilling, depending on usage.

Can I put the cast iron grates in the dishwasher?

No, cast iron grates absolutely do not belong in the dishwasher. Aggressive cleaning agents and high temperatures damage the protective seasoning layer that protects the material against rust. Clean the grates manually with a grill brush while they are still warm, and for heavy soiling rub them in with coarse salt and oil. This method keeps the grates in optimal condition.

How much space do I need for this barbecue?

Allow for a total width of approximately 140 cm including the extended side tables and a depth of approximately 120 cm including the handles. Keep at least 50 cm of clear space at the back for ventilation and safety, and do not place the barbecue under flammable materials such as an awning or pergola. The mobile construction makes it simple to move the barbecue when needed.

Is this barbecue suitable for beginners?

Absolutely. Gas barbecues are generally more user-friendly than charcoal barbecues because the temperature is easily adjustable with dials. The Leonardo starts with electronic ignition, heats up quickly and provides direct heat control. The ten-year warranty and solid construction make it a safe investment for both beginners and experienced grillers who appreciate quality.

What makes Boretti different from other barbecue brands?

Boretti distinguishes itself through the combination of Dutch product management with Italian design and high-quality materials such as cast iron grates. The brand has become well-known through appearances in programmes such as The Great Garden Renovation and is synonymous with durability and reliability. Whilst many brands use cheaper enamelled grates, Boretti deliberately chooses cast iron – the material that professional kitchens and Michelin-starred restaurants also use for superior grilling results.
