DIY Argentine Grill Build Guide
Jump to RecipeThere is a reason Argentine asado is considered one of the world's great grilling traditions. It is not just about the meat — though the meat is extraordinary — it is about the fire, the ritual, and the architecture of the grill itself. The parrilla, Argentina's iconic open-fire grill, is fundamentally different from a standard American backyard kettle grill or gas setup. It is designed to use indirect radiant heat from hardwood coals, with a height-adjustable grate that gives the asador complete, nuanced control over the cooking process. If you have been dreaming of bringing that experience to your own backyard, this DIY Argentine grill build guide will walk you through every step of making it happen.
This is an intermediate-level masonry project. You do not need to be a professional stonemason, but you should be comfortable working with mortar, reading a level, and doing some basic metalwork — or have a local welder assist with the steel components. The entire build typically takes one to two weekends of active work, plus curing time. The result is a permanent, beautiful outdoor cooking structure that will last decades and become the absolute centerpiece of every gathering you host.
Understanding the Argentine Parrilla Design
Before you buy a single brick, it is worth understanding what makes an Argentine parrilla different from other grills — because those design differences are not aesthetic, they are functional. A traditional parrilla has three key components: a firebox where coals accumulate, an adjustable-height V-shaped grate made of iron, and a side firewood compartment where hardwood is burned down to coals before being introduced beneath the cooking surface. That last point is critical. In Argentine grilling, you never cook over open flame. You cook over hot, glowing embers with zero visible flame. The wood is burned in a separate chamber, and shovelfuls of mature coals are moved underneath the grate as needed.
The V-shaped grate, called a parrilla in its own right, is angled so that fat drips to the sides and front rather than onto the coals, preventing flare-ups and acrid smoke. The height adjustment mechanism — traditionally a simple ratchet or pulley system — lets you move the grate closer to intense coals for a hard sear or pull it high and away for a long, slow cook on a whole lamb or suckling pig. This is your temperature dial, and mastering it is the heart of Argentine grilling technique.
Materials, Tools, and Planning Your Build
The single most important material choice you will make is your brick. Standard clay bricks will crack and spall when exposed to the repeated thermal shock of fire. You must use fire bricks — also called refractory bricks — for the interior firebox. These are denser, more heat-resistant, and will survive years of intense fires without degrading. Similarly, your mortar for the interior must be refractory mortar, not standard Portland cement-based mortar. For the exterior walls that are not directly exposed to flame, standard masonry mortar is perfectly adequate and much easier to source and work with.
For tools, you will need a masonry trowel, a rubber mallet, a 4-foot level, a square, a tape measure, a bucket mixer or drill with paddle bit, safety glasses, heavy gloves, and an angle grinder for cutting bricks to fit corners and edges. For the steel components — the grate, adjustment rods, and angle iron rails — either source pre-fabricated Argentine parrilla kits (widely available online) or take your measurements to a local metal fabrication shop. The steel work is the most technical part of the build, and having a professional weld the grate adjustment system is money well spent.
The Masonry Build: Step by Step
Site selection is your first decision and it matters enormously. Choose a spot that is level, well away from any combustible structure, and ideally positioned so prevailing winds carry smoke away from your home and seating area. Many Argentine parrilla builds are oriented east-to-west so the asador is not squinting into afternoon sun. Once your site is chosen, excavate 6 inches and fill with compacted coarse sand. This gives you a stable, draining base and allows for minor leveling adjustments. Do a complete dry-lay (no mortar) of your first course before committing to anything — it is far easier to adjust now than after the mortar sets.
Work in courses of no more than four rows before allowing the mortar to begin setting. Keep your joints consistent at 3/8 inch — thicker joints are weaker and look sloppy. At every third course, check for level and plumb in all directions. Small errors compound quickly in masonry, and a parrilla that is visibly out of square will bother you every time you look at it for the next twenty years. Install your steel grate support rails while the brick is still being laid — embedding them in mortar as you go, not drilling in after the fact.
Curing, Seasoning, and Firing Your First Asado
Patience during the curing phase will determine whether your parrilla lasts five years or fifty. Refractory mortar requires both time and graduated heat exposure to fully cure and achieve its maximum strength. After the initial 72-hour air cure, run a series of progressively larger fires over four days. Day one: a small kindling fire for 30 minutes. Day two: a slightly larger fire for one hour. Day three: a proper wood fire for two hours. Day four: a full-heat fire for three hours. After this sequence, your mortar is fully cured and the thermal expansion characteristics of the brick and mortar will be in equilibrium.
Season your grate by rubbing it with flaxseed oil or lard and heating it over a fire for 30 minutes, then letting it cool and repeating twice. This builds a thin polymerized layer that prevents rust and creates a natural non-stick surface. Now you are ready. Build your first fire with hardwood — in Mexico and the American Southwest, mesquite is an excellent substitute for the Argentine quebracho. Let it burn down completely in the side chamber until you have a glowing, ash-gray bed of coals with no visible flame. Shovel a generous layer under the grate, position your grate at medium height, season your meat simply with coarse salt, and lay it on. Step back. Let the fire do the work. You have built something that will gather family and friends around it for generations.
DIY Argentine Grill Build Guide
Ingredients
- 200 fire bricks (standard size 9x4.5x2.5 inches)
- 10 bags of refractory mortar (heat-resistant)
- 1 adjustable V-shaped iron grill grate (24x36 inches minimum)
- 2 steel rods or ratchet mechanism for grate height adjustment
- 1 steel firebox insert or angle iron frame (3/16 inch thick)
- 4 bags of standard masonry mortar for exterior finish
- 50 lbs of coarse sand for foundation base
- Concrete blocks or pavers for base foundation (as needed)
- Steel angle iron for grate support rails (1.5x1.5 inch, 10 ft total)
- High-temperature black paint or sealant for steel components
- Rebar (1/2 inch diameter, 20 ft) for structural reinforcement
- Ash drawer or steel sheet for ash collection (24x12 inches)
Instructions
- Plan and Prepare Your Site
Choose a level outdoor area at least 10 feet from any structure or overhanging branches. Mark out a footprint of approximately 4x3 feet for a standard home parrilla. Excavate 6 inches down and fill with compacted coarse sand to create a stable, level foundation. Allow 24 hours for the sand base to settle before beginning masonry work. Check local building codes for open-fire structures in your area before proceeding.
- Lay the Foundation and First Courses of Brick
Begin by laying a dry run of fire bricks without mortar to confirm your layout. Mix refractory mortar according to package directions and lay your first two courses of brick in a standard running bond pattern. Insert rebar vertically at all four corners, embedding it 12 inches into the sand base. Keep joints at 3/8 inch thickness and check for level constantly. The firebox interior should be approximately 24 inches wide, 30 inches deep, and will rise to about 18 inches from the ground.
- Build the Firebox and Side Walls
Continue laying fire bricks to form the firebox walls, reaching a height of 18-20 inches. At the 12-inch mark, install the steel angle iron support rails flush with the interior walls on both long sides — these will hold the grate adjustment mechanism. Leave a 4-inch gap at the front base course to allow airflow and ash removal. Mortar in the ash drawer runners on both sides of this opening. Allow each 3-4 courses to cure for 30 minutes before continuing upward.
- Install the Grate Adjustment System
The signature feature of an Argentine parrilla is the ability to raise and lower the grill grate to control heat. Weld or bolt two vertical steel rods to the inner side walls, spaced to support your grill grate width. Alternatively, install a ratchet-and-pulley system using steel cable threaded through a central bar above the grill. Attach the V-shaped iron grate (V-grooves face down to drain fat away from coals) to the adjustment mechanism. Test the grate movement through all positions — lowest should sit about 3 inches above coals, highest about 12 inches.
- Build the Upper Walls and Optional Side Shelf
Continue brick courses to bring the total grill height to 36-40 inches from ground level, which is comfortable working height. Build up one side wall an additional 8-12 courses to create a traditional side firewood holder where you will burn hardwood down to coals before shoveling them under the grate. Optionally, cap the opposite side with a concrete or brick slab to create a prep and carving surface. Ensure all walls are plumb using a level throughout.
- Apply Finishing Mortar and Cure the Structure
Once the fire brick interior is complete, apply standard masonry mortar to the exterior walls for a clean, finished look. Smooth with a trowel and allow the entire structure to cure undisturbed for a minimum of 72 hours. After curing, perform a series of small break-in fires over 3-4 days, starting with just a small kindling fire for 30 minutes, then gradually increasing fire size each session. This cures the refractory mortar properly and prevents cracking. Do not cook food until break-in fires are complete.
- Season the Grate and Fire Your First Asado
Before cooking, coat the steel grate with a thin layer of food-grade oil and heat it over a moderate fire for 30 minutes to season and prevent rust. To use your parrilla in true Argentine style, burn hardwood (quebracho, oak, or mesquite) in the side firewood holder until you have a deep bed of glowing coals with no open flame. Shovel coals evenly beneath the grate, position meat on the grate at height, and control temperature by raising or lowering the grate — never by adding raw wood directly under the meat. Welcome to your asado lifestyle.
