6 Best Toshiba 4-in-1 Microwaves of 2025

This game-changing 4-in-1 powerhouse from Toshiba redefines what a countertop microwave can do. With integrated air fry, convection, and combo cooking modes, it eliminates the need for multiple appliances while delivering crispy, golden results that rival standalone ovens. The 1.5 cu ft cavity and 13.6-inch turntable effortlessly accommodate a whole chicken or 12-inch pizza, making it ideal for families or meal preppers who demand versatility without sacrificing space.

In real-world testing, the air fry function produces impressively crisp textures with minimal oil—think golden fries and juicy wings in under 25 minutes. The convection mode heats evenly, though dense dishes like casseroles benefit from a mid-cycle turn. While the 1000W microwave power reheats efficiently, the combo cooking feature truly shines, slashing total cook time by using microwave energy to speed up convection baking. However, the learning curve for layered cooking programs may frustrate beginners, and the lack of preset air fry menus means more manual input.

Compared to the ML-EM45P(BS), this model offers far more functionality despite a slightly smaller interior. It’s a direct competitor to high-end combos like the Panasonic NN-SN966S, but at a more accessible price point with fewer premium finishes. For users seeking an all-in-one kitchen workhorse that replaces a microwave, toaster oven, and air fryer, the ML-EC42P(BS) delivers unmatched value. It outperforms basic microwaves in texture and versatility, making it the best overall choice for those who cook beyond reheating.

The Toshiba ML-EC42P(SS) brings serious multitasking muscle to compact kitchens with its quadruple-threat functionality: microwave, air fry, convection, and combo cooking. This silver-finished marvel packs 1000W of microwave power and a spacious 1.5 cu ft interior, letting you air fry wings, bake potatoes, or reheat leftovers—all without swapping appliances. What sets it apart is the smart sensor technology, which adjusts cooking time and power based on moisture levels, ensuring food doesn’t dry out.

During daily use, the convection and air fry modes deliver restaurant-quality crispness, especially with frozen foods or marinated proteins. The 13.6-inch position memory turntable stops in the same spot every time, making it safer and easier to handle hot dishes. While the external dimensions are slightly deeper than standard microwaves (21.38” depth), the trade-off is a cavity that fits full-sized baking trays. That said, the lack of preset air fry programs means you’ll need to manually set time and temperature, which can lead to trial-and-error results.

When stacked against the ML-EM45P(BS), this model offers broader cooking capabilities despite a lower wattage than some pure convection ovens. It’s a smarter investment than basic combo microwaves, especially for budget-conscious buyers who still want air frying. While the black interior hides splatters better than stainless, the silver exterior may show fingerprints. For those wanting maximum function without maxing out the budget, this is the best budget 4-in-1 that doesn’t skimp on core performance.

With a massive 1.6 cu ft capacity and 1200W of power, the Toshiba ML-EM45P(BS) is engineered for households that regularly heat large dishes or entertain guests. The 13.6-inch turntable spins smoothly and fits a 13-inch pizza with room to spare—no more awkward plate trimming. Its smart sensor technology excels at reheating leftovers evenly, automatically adjusting power to prevent cold spots or rubbery textures, a common pain point with standard microwaves.

In performance tests, the high wattage translates to faster cooking, boiling water nearly 20% quicker than 1000W models. The position memory turntable is a small but brilliant touch—returning to the same starting point every time—making it safer to remove steaming dishes. While it lacks air fry or convection functions, the one-touch popcorn button and multi-stage cooking add serious convenience for everyday use. However, it struggles slightly with delicate tasks like melting chocolate, where the power levels aren’t fine-tuned enough for precision work.

Compared to the ML-EC42P models, this microwave is simpler but larger, making it ideal for users who prioritize size and speed over multifunctionality. It’s a standout for dorms, break rooms, or secondary kitchens where you need reliable, high-volume heating without the complexity of combo cooking. While it doesn’t offer the texture control of inverter models, it delivers best-in-class capacity at a mid-tier price, making it the best large capacity option for families.

The Toshiba ML-EM45PIT(SS) stands out with its advanced inverter technology, delivering continuous, even heating that eliminates the on-off cycling of traditional microwaves. This means no more half-frozen, half-scalded leftovers—just uniformly reheated meals every time. Backed by 1250W of power and a 1.6 cu ft cavity, it’s built for serious kitchen duty, whether you’re defrosting a roast or reheating a full casserole dish. The smart sensor auto-menus adapt cooking based on humidity, making it nearly foolproof for everyday use.

Real-world testing confirms the inverter’s superiority in delicate tasks: melting butter without splatter, steaming vegetables evenly, and defrosting meat without cooking the edges. The 6 sensor menus handle common foods like pizza and potatoes with consistent results, though more complex dishes still require manual input. While the cavity is spacious, the back wall clearance requirement (1.2 inches) limits tight countertop fits. The lack of backlighting on the control panel is a minor annoyance in dim kitchens.

Against the ML-EM45P(BS), this model trades a sleeker finish for superior cooking precision thanks to inverter tech. It’s not as feature-rich as the 4-in-1 models, but for users who prioritize texture and consistency, it’s unmatched. While heavier at 33 lbs, that weight speaks to its robust build. For those who hate unevenly heated food, this is the best for even cooking, offering professional-grade performance in a home-friendly footprint.

The Toshiba ML-EM09PA(SS) is a compact dynamo tailor-made for dorm rooms, studio apartments, or office kitchens where space is at a premium. Despite its 0.9 cu ft interior, it packs 900W of power and a 10.6-inch turntable, handling everything from oatmeal bowls to frozen burritos with ease. The 6 auto menus—including popcorn, pizza, and potato—take the guesswork out of reheating, while the mute function keeps late-night snacks quiet.

In practical use, the LED lighting illuminates the cavity clearly, and the one-touch start simplifies quick heating. The two-step child lock adds peace of mind for families, though it can be slightly cumbersome for frequent adult users. While it heats efficiently, larger dishes rotate unevenly due to the smaller turntable, and dense foods like baked potatoes take longer than in higher-wattage models. It’s not built for family-sized meals, but that’s not its purpose.

Compared to the EM131A5C-SS, it offers similar features in a smaller body, making it more portable and space-efficient. It lacks the smart humidity sensor and 12 auto menus of mid-range models, but it delivers core functionality reliably. For students or singles who need a no-fuss, space-saving microwave, this is the best for small spaces, offering essential features without clutter.

The Toshiba EM131A5C-SS strikes a perfect balance between size, smarts, and performance, making it the best mid-range microwave for everyday households. Its 1.2 cu ft cavity and 12.4-inch turntable offer enough room for 90% of home cooking tasks, from reheating soup to baking potatoes, without dominating the countertop. The smart humidity sensor is the star—automatically detecting steam levels to prevent overcooking, a game-changer for busy cooks tired of dried-out leftovers.

In testing, the 12 auto menus (including sensor reheat and veggie steam) delivered consistent results with zero guesswork. The 1000W power reheats efficiently, and the ECO mode reduces standby energy, appealing to eco-conscious users. The easy-clean interior resists stains and wipes down quickly, though spills near the turntable base can be tricky to reach. It doesn’t offer air frying or inverter tech, so it won’t match premium models in texture refinement.

Pitted against the ML-EM09PA(SS), this model offers more space and smarter cooking, while avoiding the bulk of 1.6 cu ft units. It’s a direct upgrade from basic microwaves, delivering advanced features without complexity. For users who want smart cooking, reliable performance, and a footprint that fits most kitchens, this is the best mid-range pick, offering more intelligence than budget models without the steep learning curve of combos.
