Best 27 Inch Microwave Ovens Review
Café 1.5 Cu. Ft. Convection Microwave
ADVANTAGES
LIMITATIONS
This sleek, smart-enabled microwave redefines what a 27-inch countertop oven can do, blending high-end design with cutting-edge connectivity and convection cooking power. With 1,000 watts of cooking performance, a generous 1.5 cu. ft. cavity, and true convection roasting and broiling, it handles everything from reheating leftovers to baking crispy chicken skins with precision. The WiFi-enabled Scan-to-Cook feature lets you scan barcodes on frozen meals for instant, optimized settings—perfect for tech-savvy households tired of guessing cook times. It’s a game-changer for modern kitchens where convenience, consistency, and smart integration matter most.
In real-world testing, the Café unit delivers even browning and consistent sensor-based results, thanks to its humidity-sensing auto-cook technology that adjusts power and time on the fly. The convection mode runs 25% hotter and faster than standard microwaves, making it ideal for roasting vegetables or reheating pizza without sogginess. However, the turntable limits usable space for larger dishes, and the matte black finish shows fingerprints easily. While it excels in precision cooking and smart control, it’s not the most powerful in the lineup—its 1,000W output lags behind rivals, making it less ideal for rapid boiling or heavy-duty tasks.
Compared to the Summit built-in model, this Café unit trades raw power and space for smart features and countertop flexibility—and it wins hands-down for users who value voice control, app connectivity, and automated cooking. It’s not built for full integration into cabinetry, but its built-in capable design means you can upgrade later with a trim kit. Perfect for young professionals, smart homes, or minimalist kitchens where aesthetics and automation take center stage. It doesn’t match the Summit’s 1200W muscle, but it offers smarter functionality in a more compact, design-forward package.
GE 1.6 Cu. Ft. Over-the-Range Microwave
ADVANTAGES
LIMITATIONS
Don’t let the modest price tag fool you—this workhorse over-the-range microwave packs serious value into a compact 27-inch footprint, making it a top pick for budget-conscious kitchens without sacrificing core functionality. Boasting a spacious 1.6 cu. ft. interior and 1,000 watts of power, it handles everything from steaming veggies to reheating lasagna with reliable consistency. The over-the-range design frees up counter space, while the built-in ventilation system tackles smoke and odors—ideal for studio apartments or small kitchens where every inch counts. It’s the no-frills hero for renters and first-time homeowners who want performance without the premium.
During testing, the GE proved surprisingly responsive, with intuitive controls and a turntable that ensures even heating across most dishes. The pre-programmed settings for popcorn, potatoes, and beverages deliver accurate results, and the 30-second add-on button is a small but life-saving convenience. However, the interior lighting is dim, making it hard to monitor food, and the fan noise under ventilation mode is noticeably loud. While it lacks convection or smart features, it holds its own in basic and reheating tasks, though it struggles with browning or crisping compared to higher-end models.
When stacked against the Café and Summit models, this GE unit is the clear value champion—it doesn’t dazzle with features, but it delivers essential performance at a fraction of the cost. It’s not as powerful or spacious as the Summit, nor as smart as the Café, but for those prioritizing affordability, space-saving design, and reliability, it’s unmatched. It’s the go-to for students, small households, or secondary kitchens where simplicity and savings matter most. It may lack bells and whistles, but it outperforms its price point with rock-solid basics.
Summit 27″ Built-In Microwave Oven
ADVANTAGES
LIMITATIONS
If you’re after maximum cooking power and seamless kitchen integration, this beast of a built-in microwave sets the gold standard for 27-inch models, combining massive 2.2 cu. ft. capacity with 1,200 watts of output—a rare combo that dominates both family meals and gourmet prep. The stainless steel finish and full trim kit allow it to vanish into cabinetry, creating a high-end, built-in look that elevates any modern kitchen. With one-touch presets for pizza, popcorn, and frozen dinners, plus a large glass turntable and digital precision controls, it’s engineered for users who want restaurant-level performance without the bulk of a full oven.
In real-world use, the Summit shines when cooking multiple dishes or large casseroles, thanks to its cavernous interior—nearly 50% larger than most countertop models. The 1,200W power level heats liquids noticeably faster, and the convection-like performance (though not labeled as such) delivers crisp edges and even browning on baked goods. However, the digital panel can be slow to respond, and the installation process demands precision—this isn’t a plug-and-play option. It’s overkill for singles or minimalists, but for families or frequent entertainers, it’s a game-changing upgrade.
Against the Café and GE models, the Summit wins on raw capacity and power, outclassing both in cooking volume and speed. It lacks smart features, but makes up for it with professional-grade utility and seamless design. It’s the ideal centerpiece for remodeled kitchens, open-concept homes, or serious home cooks who refuse to compromise on space or performance. While it costs more than the GE and overlaps with the Café in footprint, it delivers unmatched interior volume and wattage in the 27-inch class.
Choosing the Right 27-Inch Microwave Oven
Capacity & Interior Space
The size of the microwave interior, measured in cubic feet, is a primary consideration. A larger capacity (like the 1.6 cu. ft. GE model) accommodates bigger dishes and allows for more versatile cooking. Smaller capacities (like the 1.5 cu. ft. Café model) are suitable for individuals or smaller households. Think about the types of meals you typically cook or reheat. Do you frequently use large casserole dishes or cook whole chickens? If so, prioritize a larger capacity. Conversely, if you mostly reheat leftovers or cook single servings, a smaller model will suffice.
Installation Type & Dimensions
27-inch microwaves come in built-in and over-the-range styles. Built-in models (like the Summit) require a dedicated cutout in your cabinetry, offering a seamless, integrated look. Over-the-range models (like the GE) are installed above your stovetop, saving counter space and often including ventilation features. Carefully measure your available space before purchasing. Note the specific cutout dimensions required for built-in models and ensure they match your existing cabinetry. Also, consider the overall height, width, and depth to ensure a proper fit.
Power & Cooking Features
Microwave wattage (typically around 1000-1200W) determines cooking speed and efficiency. Higher wattage generally means faster cooking times. Beyond wattage, consider the cooking features offered. Sensor cooking (Café model) automatically adjusts cooking time and power levels based on food type and moisture content, preventing overcooking or undercooking. Convection cooking (Café model) combines microwave energy with a heating element for more even cooking and browning, similar to a conventional oven. One-touch cooking options (Summit) simplify common tasks like popping popcorn or reheating leftovers.
Smart Features & Connectivity
For tech-savvy cooks, smart features can add convenience. WiFi connectivity (Café model) allows you to control the microwave remotely via a smartphone app or voice commands. This can be useful for starting or stopping the microwave while you’re busy with other tasks.
Other features to consider: Turntable size. Control panel type (digital vs. dial). Defrost settings and options. Interior lighting. Ease of cleaning (stainless steel interiors are generally easier to clean). Availability of trim kits (especially for built-in models). Warranty information.
