7 Best 48 Gas Ranges with Double Oven 2026

This culinary powerhouse redefines what a residential 48-inch gas range can achieve, delivering Italian-engineered precision and dual convection ovens that cater to large families who demand versatility and speed. With a massive 7.0 cu.ft. total oven capacity—featuring a 4.8 cu.ft. primary and 2.2 cu.ft. secondary oven—this AAOBOSI model allows simultaneous roasting, baking, and broiling without flavor transfer. The 18,000 BTU high-output burner handles searing and stir-frying like a pro, while the integrated iron grill burner adds a unique edge for indoor grilling enthusiasts, solving the common pain point of limited cooking zones in standard ranges.

In real-world testing, the convection fans and temperature probes ensure consistent results, whether you’re baking a triple-layer cake or slow-roasting a holiday turkey. The triple-insulated oven door keeps exterior temperatures safe, and the explosion-proof interior lighting provides clear visibility during long cooks. However, while the 6 sealed burners offer solid performance, the rear-right 12,000 BTU burner feels slightly cramped in larger pots due to grate layout. The removable oven door and dishwasher-safe grates are a godsend for cleanup, though the backside design sits 0.69 inches higher than countertops, which may interfere with tight cabinetry fits.

When compared to the COSMO COS-EPGR486G, the AAOBOSI trades some sleek aesthetics for greater flexibility with its built-in grill burner and LPG conversion kit included, making it a smarter pick for homes without natural gas lines. It outshines budget models in oven capacity and safety features, though it lacks the professional-grade knob illumination seen in higher-end competitors. Ideal for large families and serious home cooks who need maximum oven space and multi-method cooking, this range delivers exceptional value with robust engineering—offering more features than similarly priced models from mid-tier brands.

Step into a restaurant-grade kitchen experience with the COSMO COS-EPGR486G, a range built for those who prioritize even baking and precision heat distribution above all. Its standout feature—the fan-assisted convection system in the 4.8 cu.ft. main oven—eliminates hot spots, delivering perfectly golden cookies and evenly roasted meats every time. The 22,000 BTU bake burner ensures rapid preheating and consistent temperatures, while the 15,000 BTU griddle offers a spacious, flat cooking surface ideal for pancakes, quesadillas, or sautéed vegetables—addressing the common flaw of flimsy, removable griddles in lesser models.

During rigorous use, the triple-thick oven glass and cool-to-touch handle prove invaluable for families with kids or frequent entertainers who open the oven repeatedly. The 6 sealed burners, including an 18,000 BTU high-output option, handle most cooking tasks efficiently, though the absence of a dedicated simmer burner means low-heat sauces require extra attention. The LED indicator lights above the knobs add a modern, professional flair, but the LPG conversion kit is sold separately, which is a notable omission for propane-dependent households. The storage drawer is shallow, limiting its utility for larger bakeware.

Against the KOSTCH 48-inch range, the COSMO pulls ahead in convection performance and safety design, but falls short in included accessories and fuel flexibility. It’s a better fit for bakers and precision-focused cooks who want consistent thermal performance without the clutter of too many burners. While the BRAMA offers more burners, this model excels in thermal stability and build quality, making it the top choice for even convection baking—delivering a pro-style oven experience at a fraction of commercial costs.

The BRAMA 48-inch gas range is a feature-packed workhorse that delivers remarkable value without sacrificing performance, making it a standout for budget-conscious buyers who still want pro-style power. With 8 sealed burners, including two 20,000 BTU triple crown burners, this range offers unmatched flexibility—perfect for boiling large pots, searing steaks, or simmering delicate sauces on the 6,000 BTU auxiliaries. The continuous stainless steel grates allow seamless pan movement across burners, a detail that serious cooks will appreciate during high-volume meal prep.

In practical use, the dual convection ovens (3.5 and 2 cu.ft.) handle everyday baking and roasting with solid results, though they fall short of the larger capacities seen in AAOBOSI or DUURA models. The blue porcelain interior resists staining and is easy to wipe down, but lacks the halogen lighting or temperature probes found in premium units. While the 20A electrical requirement ensures stable convection fan operation, the 38-inch height may pose clearance issues under standard cabinets. Still, the sleek industrial handle and blue-illuminated knobs add a modern touch that elevates the kitchen’s aesthetic.

Compared to the Forno Galiano, the BRAMA offers similar burner count and output but lacks dual-ring technology and infrared broil, making it less ideal for high-heat searing. However, it beats the KOSTCH in burner variety and simmer control, and at a competitive feature set, it’s a smarter buy for home chefs seeking maximum functionality per dollar. For those who cook frequently but don’t need European convection or commercial BTUs, this range delivers the best balance of price, power, and polish—offering more cooking zones than most rivals in its class.

If your breakfast game includes pancakes, grilled sandwiches, or fajitas, the KOSTCH 48-inch range is engineered for griddle lovers who want dedicated, high-output flat-top cooking without sacrificing oven functionality. The 15,000 BTU integrated griddle burner heats quickly and maintains even temperature across its surface—outperforming removable griddles that warp or cool unevenly. Paired with six 12,000–18,000 BTU burners, this setup gives you full cooktop control, while the included NG/LPG conversion kit ensures compatibility with both fuel types, a major win for off-grid or rural kitchens.

Real-world testing shows the double convection ovens (4.6 and 2.2 cu.ft.) bake reliably, though the fan can be noisy at high speeds. The high-gloss enamel-coated oven doors resist fingerprints and maintain a premium look over time—unlike cheaper powder-coated finishes that chip. However, the rear burners are closely spaced, making it tricky to use large skillets simultaneously. The adjustable legs help with uneven floors, but the height range (36.63–37.9 inches) may exceed standard countertop clearances in some kitchens.

Next to the Gordon Ramsay by THOR Kitchen model, the KOSTCH offers similar griddle performance and oven size but at a more accessible feature tier—missing the commercial convection tuning and brand prestige. It’s a better fit than the COSMO for families who cook breakfast daily or love weekend brunch spreads. While the DUURA offers more burners, this model wins on griddle integration and fuel flexibility, making it the clear leader for griddle-centric cooking—delivering pro-style surface performance with home-friendly convenience.

Crafted for aspiring professional home chefs, this Gordon Ramsay-branded THOR Kitchen range brings commercial-level precision and power into the domestic kitchen, where performance trumps frills. The 22,000 BTU bake burner in the 4.6 cu.ft. oven ensures rapid preheating and rock-solid temperature stability—critical for delicate pastries or multi-rack roasting. Combined with the commercial convection fan, this system mimics true restaurant ovens, solving the common issue of uneven baking in residential units. The 15,000 BTU integrated griddle adds serious versatility, perfect for searing scallops or cooking hash browns in bulk.

In daily use, the high-performance burners (12,000–18,000 BTU) deliver responsive flame control, ideal for techniques like deglazing or flambéing. However, the lack of a low-output simmer burner means delicate reductions require careful monitoring. The 2.2 cu.ft. secondary oven is useful for warming or small dishes but doesn’t match the capacity of competitors like AAOBOSI or DUURA. Build quality is excellent, with heavy-duty stainless steel and smooth knob action, though the design is minimalist—missing LED lights or storage drawers found in other models.

Compared to the BRAMA, this range trades burner count and storage for superior thermal consistency and brand-backed engineering. It’s less about quantity and more about refined cooking performance, making it ideal for serious home chefs who follow Gordon Ramsay’s high-heat, precision-driven style. While the Forno Galiano offers higher total BTUs, this model excels in oven reliability and heat retention, delivering a restaurant-like experience—where cooking precision outweighs sheer feature count.

The DUURA Elite DE480GRSKIT1 stands as the best overall 48-inch gas range, combining professional-grade performance, thoughtful design, and comprehensive safety features into one seamless package. With 8 sealed high-power burners and continuous heavy-duty grates, it enables effortless pan shifting across the entire cooktop, a game-changer for chefs managing multiple dishes. The 6.7 cu.ft. total oven capacity—split into dual porcelain convection ovens—handles holiday feasts with ease, while the integrated broil function delivers crisp, golden finishes on casseroles and meats.

In testing, the porcelain convection ovens heated faster and retained temperature better than enamel-coated rivals, thanks to optimized fan placement and insulation. The stainless steel construction resists warping and stains, and the Arrow Industries gas connector kit included in-box simplifies safe installation—a rare and welcome inclusion. However, the storage drawer is narrow, limiting its utility, and the knobs lack backlighting, reducing visibility in dim kitchens. Still, the 1-year CPS extended warranty adds real peace of mind beyond standard coverage.

Against the AAOBOSI and BRAMA, the DUURA strikes the perfect balance of power, capacity, and reliability, outperforming both in build quality and included accessories. It’s more versatile than the KOSTCH and safer than the Forno, making it ideal for homeowners upgrading to a luxury kitchen or building a high-performance cooking space from scratch. While the Gordon Ramsay model appeals to purists, this range delivers the most complete, well-rounded experience—offering pro-level features, durability, and convenience in one commanding footprint.

When raw power and high-BTU performance are non-negotiable, the Forno Galiano emerges as the undisputed king of flame-driven cooking, delivering a staggering 107,000 BTU total output across 8 sealed brass burners. Its dual-ring 20,000 BTU burner offers precise control from a roaring boil to a gentle simmer, while the 9,000 BTU low-output burners provide true simmering capability—a rarity in this class. The reversible cast-iron griller adds another dimension, letting you sear steaks indoors with restaurant-level char, directly solving the limitation of fixed griddles.

In real-world use, the True European convection system and infrared broil element (10,000 BTU) produce exceptional roasting and browning results, outperforming standard convection in rival models. The 3-layer oven door and soft-close mechanism enhance safety and usability, while the 2-year factory warranty reflects confidence in durability. However, the 4.32 cu.ft. main oven is smaller than competitors’, limiting large turkey or sheet pan capacity. The 15,000 BTU grates are heavy, making cleaning cumbersome, and the 38–39 inch height requires custom cabinetry clearance.

Versus the Gordon Ramsay THOR model, the Forno offers higher total BTUs and better simmer control, but lacks the brand-tuned convection programming. It’s a better fit than the BRAMA for chefs who live by high-heat techniques—wok cooking, searing, and broiling. While the DUURA wins on overall balance, this range dominates in maximum cooking intensity, making it the top pick for high-BTU cooking—where fire, flavor, and control reign supreme.
