Chicago Brick Oven: The Honest Wood-Fired Pizza Oven Guide

Brand Background

Chicago Brick Oven — CBO for short — started in a Chicago backyard when the founders wanted a real wood-fired oven for their own family cooking and couldn’t find one at a price point that made sense for residential use. They built one, then built more for neighbors, and eventually turned it into a full manufacturing operation that’s been shipping American-made ovens for over 20 years.

The brand’s ovens are used in restaurants, food trucks, and residential backyards across the country. That commercial-and-residential crossover is a useful signal — CBO ovens are engineered to survive 200+ pizzas a night in a restaurant setting, which means they’re dramatically over-built for the 4-6 pizzas most families cook on a weekend. Residential buyers get the same refractory dome and same hearth material as the professional kitchens.

What separates CBO from the flood of imported pizza ovens that flooded the market in 2020-2022 is genuinely-American manufacturing and refractory formulation tuned for real outdoor use. Cheaper imports use lower-grade refractory that cracks after 100 firing cycles; CBO’s dome is warrantied for 10 years and typically outlives the outdoor kitchen it’s built into.

The Four Residential Models

CBO’s residential line splits into three sizes plus a hybrid heat-source option.

CBO-500 Countertop is the entry model — 27-inch cooking surface, fits one 12-inch pizza plus room for a side, ships fully assembled in your choice of four finishes (Black, Copper, Silver, Stainless Steel). Best for families cooking for 2-4 who want a real wood-fired oven without committing to a permanent build. Sits on any properly-rated counter or CBO stand. Typical price ~$4,700 depending on finish.

CBO-750 Countertop steps up to a 34-inch dome — cooks two 12-inch pizzas simultaneously or one 16-inch. Same fully-assembled countertop drop-in as the 500, same four finishes. This is our most-recommended CBO for buyers who host regularly (6-8 person dinners rather than 2-4). About $6,200 at typical configuration.

CBO-750 Hybrid Built-In Kit uses the same 34-inch dome but ships as a component kit with a natural gas burner integrated alongside the wood chamber. Designed for permanent installation into a masonry outdoor kitchen — dome, hearth, insulation, chimney all install into the surround. Around $8,000 with the gas burner included.

CBO-1000 DIY Kit is the flagship — 42-inch dome, up to three 12-inch pizzas at once, ships as component parts for owner or mason assembly into a permanent structure. About $8,400 for the kit; add mason labor and outdoor kitchen chase costs for the full build. Sized for entertainers and buyers planning to fire the oven 3-4 times per week.

Wood-Fired vs Hybrid: Which Is Right?

The single biggest decision for a CBO buyer is wood-only vs the Hybrid gas-assist option.

Wood-only delivers the authentic wood-fired experience — real fire visible in the dome, real smoke character, real 45-60 minute warm-up from cold. The pizza tastes different because it IS different. Live-fire cooking has a flavor and theater that gas-assist doesn’t replicate. Buy wood-only if the ritual is part of what you’re buying: sourcing hardwood, building the fire, waiting for the dome to blacken then white-out, cooking at the peak of the oven’s temperature curve.

Hybrid (wood + gas) adds a natural gas burner that reaches pizza temperature in 20-25 minutes without wood, and lets you top up heat during a long session so the oven holds steady at 700°F+ through cooking for a crowd. You give up some of the wood-fire theater and a percentage of the wood-smoke flavor, but you gain enormous weeknight flexibility — the oven is ready by the time drinks are poured.

Our recommendation: if you’ll cook 5+ times a month, buy Hybrid — the warm-up time reduction is what will keep you actually using it during the week. If you’ll cook 1-3 times a month and the wood-fire ritual is part of the pleasure, buy wood-only.

Countertop vs Built-In DIY Kit

CBO-500 and CBO-750 Countertop models ship fully assembled — you set them on a rated counter or the CBO steel stand, connect the gas line if Hybrid, done same day. These are the right choice for buyers who don’t want a construction project.

The CBO-750 Hybrid Built-In Kit and CBO-1000 DIY Kit ship as component parts. Refractory dome, refractory hearth, chimney and cap, ceramic insulation blanket, and hardware — you or a mason assemble them into a permanent stucco, brick, or stone outdoor kitchen. Budget 1-2 weekends for a DIY assembly, or 3-5 days for a professional mason. The reward is a permanent oven built into the outdoor kitchen’s aesthetic — nothing looks better than a proper wood-fired dome integrated into a stone or stucco surround.

For most residential buyers, we recommend Countertop unless you’re already doing a full outdoor kitchen build. The construction time and cost of a DIY kit installation typically doubles the effective spend when you factor in surround materials and labor.

Cool Uses Beyond Pizza

Pizza is the highest-profile use, but it’s not the only one — and most CBO owners find themselves cooking a wider range in year two than they expected in year one.

Wood-fired bread is where a CBO shines after pizza. A 500°F oven bakes baguettes, sourdough, focaccia, and pan bread with the crust color and oven spring you can’t replicate in a home kitchen. Bake bread after pizza while the oven is coasting down through the 400-500°F range — the residual heat is free energy already paid for.

Slow-roasted meats use the same residual-heat window. A whole chicken at 400°F for 45 minutes, a pork shoulder at 300°F for 6 hours, a beef roast at 350°F with wood-smoke character — all cook beautifully in the oven after the pizza rush is done. This is where CBO owners start to justify the investment on a weekly basis rather than a monthly one.

Roasted vegetables pick up wood-smoke character that changes them from side dish to feature. Whole heads of garlic, cherry tomatoes on the vine, tri-color peppers, hasselback potatoes, cast-iron corn on the cob — all benefit from the high radiant heat and the smoke.

Cast iron and dutch oven cooking — paella, cassoulet, braises, seared steaks in a cast iron skillet — take on a smoke character that indoor stoves can’t match. The oven becomes a general-purpose high-heat outdoor kitchen tool, not just a pizza oven.

What Makes Chicago Brick Oven Different

Three things separate CBO from the flood of imported pizza ovens that hit the market in the post-2020 outdoor-cooking boom.

American refractory formulation — CBO’s dome and hearth are cast from a refractory mix engineered for outdoor thermal cycling. Ovens that live outside experience daily temperature swings that indoor commercial ovens don’t. Cheaper imported ovens use interior-rated refractory that cracks after a season or two of freeze-thaw cycles. CBO’s formulation is designed for the outdoor environment and warrantied for 10 years accordingly.

Refractory dome thickness. CBO uses a 2-inch-thick refractory dome across the residential line. Many competing ovens use 1-inch or thinner domes to reduce weight and cost. The extra thickness holds heat longer, recovers faster between pizzas, and dramatically extends the oven’s useful cooking window after the fire dies down.

Serviceability. CBO ships replacement parts (refractory patches, chimney sections, gas burners on Hybrid) directly from Chicago. Cheaper imported ovens often become disposable when a component fails — no domestic parts network, no field-repairable joints. A CBO oven bought today is still service-able in year 15.

Honest Downsides

CBO isn’t the cheapest wood-fired oven on the market. Ooni, Gozney, and imported alternatives start at $500 for a small tabletop unit. CBO-500 starts around $4,700. You’re paying for domestic manufacturing, heavier refractory, and 10-year warranty terms — but if your budget is $1,000 for a pizza oven, CBO isn’t the right brand.

Wood-only models require sourcing seasoned hardwood — oak, hickory, cherry, or fruit woods. In most US markets this is easy (local firewood suppliers, home improvement stores in fall/winter), but if you live somewhere where hardwood is expensive or scarce, the Hybrid gas-assist option is a better fit.

The DIY Kits are real construction projects. If you’re not comfortable working with masonry or hiring a mason, don’t buy a DIY Kit — buy the CBO-500 or CBO-750 Countertop instead. We’ve seen buyers underestimate the assembly effort on the CBO-1000 and end up with an unfinished pile of refractory in their yard for a year.

Who Should Buy Which

Buy CBO-500 Countertop if you cook for 2-4, host a few times a month, want the countertop drop-in installation, and don’t need to cook two pizzas simultaneously. Best entry point to the brand.

Buy CBO-750 Countertop if you cook for 4-8, host regularly, want the countertop drop-in installation, and want the option to cook two pizzas at once for family-style dinners. Our most-recommended CBO for most residential buyers.

Buy CBO-750 Hybrid Built-In Kit if you’re already doing a full outdoor kitchen build, you want the permanent integrated look, and you want the weeknight flexibility of gas-assist warm-up. Best for buyers planning to cook 5+ times per month year-round.

Buy CBO-1000 DIY Kit if you’re building the outdoor kitchen of a lifetime, you entertain for 10+ people regularly, and either you or a mason will handle the construction. Overkill for most residential use — but the right pick for the buyers it’s built for.

What to Ask Before You Order

Confirm the finish availability if you’re ordering a CBO-500 or CBO-750 Countertop — the four finishes (Black, Copper, Silver, Stainless) can run different lead times depending on demand cycle. Copper tends to be the longest wait.

If you’re ordering a Hybrid model, confirm your gas type at order (natural gas vs propane) — field conversion is possible but requires a $200-400 conversion kit and licensed gas fitter labor. Getting the fuel right at order saves the effort.

For the DIY Kits, ask about the chimney termination requirements for your specific installation. Local code varies on distance from combustibles, height above roofline, and cap style. Better to know the constraints before you start pouring the hearth than to find out during final inspection.

Register the warranty within 30 days of delivery. The 10-year refractory coverage requires online registration to lock in — a small step that a lot of buyers skip and regret in year eight when a hairline crack starts to grow.
