CosmoGrill Outdoor XL Smoker Barbecue Review & Best UK Price (2026)

Design: A Barrel of Fun

The CosmoGrill Outdoor XL Smoker Barbecue mimics the classic "oil drum" silhouette of competition smokers. It features a main chamber for grilling/smoking and a separate side firebox for that authentic offset smoking experience.

It looks the part. The matte black finish and chunky wheels give it a rugged, pitmaster vibe. It’s not built from the thickest steel in the world (you’d need to pay triple for that), but for the price, it’s a surprisingly competent entry-level rig.

Performance: Low & Slow

This grill is a dual-threat. You can grill burgers directly over coals in the main chamber, OR you can build a fire in the side box and channel smoke across the food for hours.

Capacity: It is XL by name and nature. You can easily fit 3 whole chickens or a massive brisket in the main chamber.
Temperature Control: The chimney damper and side events allow you to regulate airflow, though it takes a bit of practice to master (which is half the fun).
Versatility: Use charcoal for high heat or wood chunks for smoke flavour. The warming rack is handy for buns or resting meat.

Assembly

Prepare for a bit of a project. It comes flat-packed with quite a few components. Give yourself 2 hours and a clear workspace. The instructions are decent, but having a second pair of hands helps when attaching the legs and firebox.
