Open-flame grates against flat-top solid steel
The choice between the Weber Spirit E-310 and the Blackstone 36 Omnivore Griddle comes down to heat transfer physics: convective/radiant flame versus conductive contact searing.
- Weber Spirit E-310 (Gas Grill): Features three stainless steel burners delivering 24,000 BTU under heavy porcelain-enameled cast-iron grates. Grease drippings vaporize on Flavorizer bars to produce classic barbecue aroma and flame char, while the deep lid enables indirect convective roasting.
- Blackstone 36 Omnivore (Flat-Top Griddle): Features four independent burner zones beneath a continuous 36-inch solid carbon steel plate. Because there are no grate openings, foods cook in their rendered juices, enabling breakfast diner cooking, smashburgers with edge-to-edge Maillard crust, fajitas, and fried rice.

| Heat Transfer | Open flame & radiant grates | Direct conductive steel contact |

Cooking capabilities compared
Where the Weber Spirit E-310 wins
- Steak and chop sear marks: Cast-iron grates store heavy thermal mass, creating diamond sear patterns and flame-licked smoky crusts.
- Convective roasting: Lowering the lid turns the Spirit into an outdoor oven. You can roast whole chickens, bake potatoes, or set up two-zone indirect heat for thick pork loins.
- Low maintenance: Porcelain-enameled grates resist moisture and rust with minimal seasoning upkeep.
Where the Blackstone 36 Omnivore wins
- Edge-to-edge Maillard browning: Smashburgers pressed against flat steel develop a continuous crispy crust that is impossible to achieve over open grates.
- Small and delicate foods: Sautéing diced onions, mushrooms, bacon strips, shrimp, scrambled eggs, and pancakes without anything dropping through grates.
- Four distinct heat zones: Keep buns warming on the far left at low heat while searing beef patties on the right at high heat.
Who each one is for
Choose the Weber Spirit E-310 if you want an everyday backyard cooker for traditional burgers, ribeyes, bone-in chicken, and indirect barbecue with minimal maintenance.
Choose the Blackstone 36 Omnivore Griddle if you love hosting large family gatherings, cooking diner breakfasts (pancakes, eggs, bacon), crafting ultra-crispy smashburgers, or whipping up high-heat teppanyaki and fajitas.
Common questions
- Can you bake or roast chicken on a Blackstone griddle?
- You can use melting domes to trap heat over individual items, but the Blackstone is primarily a direct conductive cooking surface. The Weber Spirit E-310 has a deep insulated cookbox designed for convective roasting with the lid down.
- How does cleaning differ between open grates and flat-top steel?
- The Weber uses porcelain-enameled cast iron grates cleaned with a grill brush while hot. The Blackstone uses a solid cold-rolled steel plate that requires scraping, water steaming, and oil seasoning maintenance similar to a cast-iron skillet.
- Which cooker accommodates more food for large parties?
- The Blackstone 36 offers 768 square inches of continuous solid flat-top space, easily cooking 28 smashburgers, dozens of eggs, or mounds of fried rice simultaneously without food falling through grates.
- Do both run on standard 20 lb liquid propane tanks?
- Yes. Both connect directly to standard 20 lb refillable liquid propane tanks using included regulator hoses.
