A capable gas grill does not have to cost a fortune. In the under 100 category, the right propane grill gives you fast preheat, even heat across the cooking surface, and enough room to feed a family on a weeknight. The trick is knowing which specs actually matter so you avoid the flimsy models that warp after a season and burn through fuel.

When shopping in this range, focus on the number of burners, total BTU output, and grate material. More burners let you create separate heat zones for searing and slow cooking at the same time, while cast iron grates retain heat better and produce cleaner sear lines than thin chrome wire. A side burner, sturdy legs, and easy-to-clean grease management round out a grill that will last well beyond its first summer.

Key buying factors

Number of Burners

Burner count determines how much control you have over your cook. A two-burner grill suits couples and small meals, while three or four burners let you run separate heat zones for searing, roasting, and keeping food warm all at once.

Total BTU Output

BTU measures how much heat the grill can produce, with most budget models landing between 24,000 and 38,000. Higher BTU helps the grill recover heat quickly after the lid opens, but pair it with a reasonable cooking area so the heat is concentrated rather than wasted.

Grate Material

Cast iron grates hold heat far better than thin chrome wire and deliver crisp sear marks on steaks and burgers. They do require seasoning and a little extra care, but the cooking results and longevity make them worth it in this price range.

Side Burner

A built-in side burner lets you simmer sauces, saute onions, or boil corn without running back to the kitchen. It is a genuine convenience for full meals and is increasingly common even on affordable multi-burner grills.

Portability and Footprint

Decide whether you want a permanent backyard grill or a portable model for tailgating and camping. Folding legs and compact single-burner designs travel easily, while larger four-burner carts need dedicated patio space.

Build Quality and Materials

Look for stainless steel components, solid legs, and a stable cart or frame that will not wobble in use. Quality construction resists rust and warping, which is what separates a grill that lasts years from one that fails after a season.

Types explained

Multi-Burner Cart Grills

These three and four-burner propane grills mount on a wheeled cart for backyard use and offer the most cooking area and heat-zone flexibility. They typically pair higher BTU output with cast iron grates for serious searing power.

Best for: Families and frequent hosts who want full-size grilling capacity.
Compact Two-Burner Grills

Two-burner models strike a balance between cooking space and a smaller footprint, often adding a side burner for sauces and sides. They suit couples, small patios, and anyone who grills a few times a week.

Best for: Small households and tight outdoor spaces.
Portable Single-Burner Grills

These lightweight, lid-down designs are built to travel for tailgating, camping, and balcony cooking. They sacrifice surface area for true portability and quick setup wherever you go.

Best for: Campers, tailgaters, and apartment dwellers.
Folding Propane Grills

Grills with folding legs or collapsible frames combine respectable burner counts with easy storage and transport. They give you multi-burner cooking that tucks away when the season ends.

Best for: Buyers short on storage who still want multiple burners.

Care & usage tips

Season Cast Iron Grates Before First Use

Coat new cast iron grates with a thin layer of high-smoke-point oil and heat the grill for fifteen to twenty minutes. This builds a protective layer that prevents rust and stops food from sticking, and repeating it occasionally keeps the surface in top shape.

Burn Off and Brush After Every Cook

Run the burners on high for several minutes after grilling to carbonize residue, then scrape the grates with a sturdy brush. This simple habit keeps flavors clean and prevents buildup that can cause flare-ups.

Empty the Grease Tray and Cover the Grill

Clean the grease cup or tray regularly to avoid grease fires and pests, and store the grill under a fitted cover. Protecting it from rain and sun dramatically extends the life of the grates, burners, and frame.

Why this matters

Total BTU is the number buyers fixate on, but BTU per square inch of cooking surface matters far more. A grill with high BTU spread across a large surface can actually struggle to sear, while a more modest BTU rating concentrated over cast iron grates often runs hotter and more evenly where it counts.

Pro tip

Light the grill with the lid open every time, then close it and let it preheat fully so the grates reach searing temperature before food touches them. Preheating on cast iron is the single biggest factor in clean release and good grill marks.

Frequently asked questions

Can you get a good gas grill for under 100?+

Yes. The under 100 range includes capable multi-burner propane grills with cast iron grates and even side burners. The key is matching burner count and BTU to how you cook rather than chasing a single spec.

How many burners do I really need?+

Two burners handle small meals and couples, three burners suit most families with room for heat zones, and four burners are best for large gatherings. More burners give you better temperature control across the surface.

Are cast iron grates better than other materials?+

Cast iron retains heat exceptionally well and produces the cleanest sear marks, which is why it is preferred in this price range. It needs occasional seasoning and care, but the cooking results and durability are worth the small effort.

What size propane tank do these grills use?+

Most full-size and portable propane grills in this category connect to a standard refillable propane tank, and some portable models also accept smaller disposable canisters. Always confirm the connection type and check the hose and regulator for the right fitting before your first cook.

Are budget gas grills safe to use?+

Yes, when assembled correctly and maintained. Check all connections for leaks with soapy water, keep the grease tray clean, light with the lid open, and never leave a lit grill unattended.
