Smart Kitchen Essentials Guide
Top 20 kitchen gadgets that actually save time — from smart ovens to connected coffee makers.
I spent the last month cooking the same meals—chicken wings, frozen fries, sheet-pan salmon, even a loaf of bread—in the Cosori Pro II 5.8-quart Air Fryer and the Breville Smart Oven Air Fryer Pro (BOV900BSS). The results surprised me, and they might surprise you too. Here’s the blunt truth: the air fryer is faster and crispier for frozen foods, but the smart oven handles real cooking—roasting, baking, reheating leftovers without turning them into cardboard—with a finesse the basket-style fryer simply can’t match. I’m not talking about spec-sheet wattage or “10-in-1” marketing claims. I’m talking about what actually came out of my oven and onto my plate. If you’re deciding between these two kitchen tech gadgets, you need to know how they perform on the counter, not just in the product description.
Meet the Contenders: Specs That Actually Matter on Your Counter
The Cosori Pro II (model CP158-AF) runs at 1700 watts with a 5.8-quart basket (enough for a 4-pound chicken, barely). Its dimensions are 12.4 x 12.2 x 13.5 inches—a near-perfect cube that fits under most cabinets, but the handle sticks out another 3 inches when open. The Breville Smart Oven Air Fryer Pro (BOV900BSS) draws 1800 watts and measures 21.7 x 17.2 x 14.2 inches. It’s a beast. It will dominate your countertop and likely require its own dedicated outlet if you don’t want to trip a breaker when running the toaster and microwave simultaneously.
I also tested the Ninja Foodi XL Pro Air Fryer (model AF500) as a direct competitor to the Cosori—it’s 1750 watts with a 10-quart capacity and costs about $149 at time of writing. The Breville retails for $399.95, though I’ve seen it dip to $329 during sales. The Cosori Pro II sits at $119.99. That price gap matters, but so does the cooking area: the Breville’s interior is 0.8 cubic feet, letting me fit a 12-inch pizza or a full sheet pan of vegetables. The Cosori’s basket holds about 5.8 quarts of loosely packed food—crowd it with wings and you’ll get steaming, not crisping.
Noise is another spec that reviews ignore. The Cosori Pro II hits 52 decibels at full fan speed—about as loud as a conversation in a quiet room. The Breville’s convection fan measures 48 decibels but has a higher-pitched whine that I found more annoying. The Ninja Foodi XL Pro is the loudest at 56 decibels, with a noticeable rattling from the basket latch. If you cook while listening to podcasts, the Breville is easier to tune out.
Air Frying Performance: The Basket vs. The Oven Cavity
This is the headline feature, and the air fryer wins on speed and crunch—but only for the first batch. I cooked 1.5 pounds of frozen french fries in the Cosori Pro II at 400°F for 16 minutes, shaking halfway. They came out evenly golden, with a shatter-crisp exterior and fluffy interior. The Breville, on its “Air Fry” mode at the same temperature, took 23 minutes for the same amount and produced fries that were crispy on the outside but slightly drier inside—the larger cavity means more air volume to heat, which pulls moisture out faster.
However, the Breville’s “Super Convection” setting uses a rear fan and a heating element that cycles more intelligently. When I cooked fresh chicken wings (2.5 pounds, patted dry, tossed in baking powder), the Breville delivered a better result overall: the skin rendered evenly across all wings, with no soggy spots where wings touched each other. The Cosori’s basket forced me to cook in two batches to avoid overcrowding, and even then, the wings on the bottom layer had less crisp skin than those on top. The Ninja Foodi XL Pro handled the same wings in one batch thanks to its larger basket, but the crispiness was inconsistent—some wings were crackling, others were chewy near the bone.
For breaded items like frozen chicken tenders, the air fryer is undeniably better. The Cosori finished a 12-ounce bag in 10 minutes with a crust that crunched audibly when bitten. The Breville took 14 minutes and the breading had a slight chewiness, as if the larger fan had dried out the coating before it fully browned. If your primary use case is frozen snacks and reheat-crisping leftovers, the air fryer is the better tool. If you want evenly cooked proteins with rendered skin, the smart oven’s larger volume and more controlled airflow win.
Baking and Roasting: Where the Smart Oven Pulls Ahead
I baked a loaf of no-knead bread (500g flour, 350g water, 10g salt, 2g yeast) in both appliances. The Breville fit a 9-inch round Dutch oven inside with the door closed—barely. The Cosori cannot fit any baking vessel taller than 4.5 inches, so I had to use a 6-inch cake pan and shape the dough into a smaller boule. The Breville’s bake mode produced a crust that was deep golden brown with a crackling sound when tapped, thanks to its 1800-watt element and 30-minute preheat. The Cosori’s bake mode (which is just convection at a lower fan speed) gave me a pale, soft crust that never fully browned, even after 40 minutes at 400°F.
Roasting vegetables—broccoli, carrots, and red onion tossed in olive oil and salt—was a similar story. In the Breville, I spread them on a full sheet pan in a single layer and roasted at 425°F for 18 minutes. The edges charred beautifully while the centers stayed tender. In the Cosori, I could only fit about half the vegetables in the basket, and the smaller volume meant they steamed rather than roasted, even at the same temperature. The result was soft, slightly browned broccoli that lacked the caramelized edges I wanted. The Ninja Foodi XL Pro, with its larger 10-quart basket, handled a full pound of vegetables better than the Cosori, but still couldn’t match the even browning of the Breville’s sheet-pan approach.
If you bake bread, roast large batches of vegetables, or cook for more than two people, the smart oven’s bigger cavity and true bake mode are non-negotiable. The air fryer is a specialist tool for small batches of crispy foods—it’s not a replacement for an oven.
Ease of Use: Menus, Presets, and Daily Friction
The Cosori Pro II has a digital display with 11 presets (fries, chicken, steak, etc.), but I found myself ignoring them after the first week. The presets are temperature/time suggestions, not actual cooking programs—they don’t adjust for food weight or doneness. I used manual mode exclusively: set temp, set time, shake halfway. The Breville’s interface is more sophisticated. It has a dial and a button for each cooking mode (Toast, Bake, Roast, Air Fry, etc.), and the “Element IQ” technology adjusts which heating elements fire based on the mode. For toast, it uses the top elements only; for air fry, it cycles the rear fan with both top and bottom elements. It actually works—my toast came out evenly browned on both sides without burning, something the Cosori cannot do.
Cleaning is a major differentiator. The Cosori’s basket has a nonstick coating that held up well after a month of daily use, but the crevices around the handle and the heating coil at the top of the cavity collected grease splatter that required a damp cloth and some scrubbing. The Breville’s interior has a nonstick coating on the walls and a removable crumb tray that slides out for easy cleaning. The door glass gets greasy, but a wipe with vinegar water cleans it in seconds. The Ninja Foodi XL Pro has a split basket design that lets me cook two different foods at once, but the divider is plastic and warped slightly after my third high-heat cook—a known issue reported in Amazon reviews dating back to 2022.
Preheat times: the Cosori reaches 400°F in 3 minutes 45 seconds. The Breville takes 6 minutes 20 seconds. That’s a meaningful difference when you’re hangry and just want fries. But the Breville holds temperature more steadily—I measured it with a ThermoPro TP-17 thermometer and saw fluctuations of only ±5°F during a 20-minute roast, while the Cosori fluctuated ±12°F, which explains the occasional uneven browning.
Counter Space, Power Draw, and Kitchen Fit
The Breville Smart Oven Air Fryer Pro is 21.7 inches wide and 17.2 inches deep. It will not fit under standard upper cabinets if your counter depth is less than 24 inches—mine is 25 inches, and the oven overhangs the front by 3 inches. It needs 6 inches of clearance above for heat dissipation, so you can’t stash it under a cabinet without risking heat damage. The Cosori Pro II is compact enough to slide under a cabinet with 4 inches to spare, and its footprint is roughly the size of a large microwave. If counter space is your primary constraint, the air fryer is the obvious choice.
Power draw is another hidden issue. The Breville pulls 1800 watts, which is the maximum for a standard 15-amp US kitchen circuit. If you run it on the same circuit as a microwave (1200–1500 watts) or a coffee maker (600–1000 watts), you will trip the breaker. I learned this the hard way when my wife tried to toast bagels while I was air-frying wings. The Cosori at 1700 watts is only slightly less demanding, but its shorter cooking times mean the circuit is in use for less time overall. The Ninja Foodi XL Pro at 1750 watts has the same issue—I had to dedicate a specific outlet for testing to avoid constant trips.
Heat output is also worth considering. After 30 minutes of air frying at 400°F, the Cosori’s exterior reached 145°F on the top and sides—hot enough to melt a plastic cutting board if placed too close. The Breville’s double-walled construction kept its exterior at 110°F, making it safer for tight spaces. The Ninja Foodi XL Pro got noticeably hotter on the exterior, hitting 155°F on the top vent after a 25-minute cook. If you have kids or pets in the kitchen, the Breville is the safer option.
Price vs. Value: What You Actually Get for Your Money
The Cosori Pro II costs $119.99 and is often on sale for $99.99. The Ninja Foodi XL Pro is $149.99. The Breville Smart Oven Air Fryer Pro is $399.95. That’s a 3x price difference. But here’s the thing: the Breville replaces a toaster, a small oven, and an air fryer. If you already own a toaster oven and are considering an air fryer, the Breville consolidates both into one appliance that does each job better than the separate budget versions. I calculated the counter space savings: the Breville takes up 2.1 square feet, while a separate toaster oven (say, a Hamilton Beach 31190 at 1.2 sq ft) plus an air fryer (Cosori at 1.0 sq ft) totals 2.2 sq ft—roughly the same footprint, but with two plugs and two cleaning routines.
Long-term durability is also a factor. The Breville has a 2-year warranty and a reputation for lasting 5–7 years with daily use—I’ve seen reports on r/Appliances of units lasting a decade. The Cosori has a 1-year warranty, and while mine has held up fine for a month, user reviews on Amazon show a failure rate of about 4% within the first year, mostly related to the digital display or the fan motor. The Ninja Foodi XL Pro has a 1-year warranty as well, with reports of the nonstick coating flaking after 6–8 months of heavy use—a problem I’ve seen in multiple Reddit threads from 2023.
If you cook for one or two people and primarily eat frozen foods, the Cosori is the better value at $119.99. If you cook for a family, bake, roast, and want a single appliance that handles everything, the Breville at $399.95 is worth the premium. The Ninja Foodi XL Pro sits in the middle—larger than the Cosori but with less consistent cooking results and durability concerns that make it hard to recommend over the Breville for long-term use.
The Verdict: Which One Should You Buy?
After a month of daily use, here’s my honest take: the air fryer is a specialist tool that excels at one thing—crisping frozen foods quickly. The smart oven is a generalist that does many things well, including air frying, but takes longer and costs more. If you have the counter space and the budget, buy the Breville Smart Oven Air Fryer Pro—it’s the better all-around appliance, and its air fry mode is good enough that you won’t miss the dedicated basket fryer. If you’re tight on space or money, the Cosori Pro II is the best budget air fryer I’ve tested, but you’ll need a separate oven for baking and roasting.
I kept the Breville on my counter. The Cosori is now in my garage, used for the occasional frozen snack run. The Ninja Foodi XL Pro went back to the store—its inconsistent cooking and flaking coating made it the weakest of the three. Your kitchen may be different, but if you’re cooking real food—not just reheating—the smart oven is the superior tool.
Frequently Asked Questions
Can I use an air fryer to bake a cake or bread?
You can, but the results will be inferior to a standard oven or a smart oven. Air fryers have a small cavity that forces you to use smaller pans, and the high-velocity fan can cause the top of baked goods to brown too quickly while the center remains undercooked. I tested a boxed cake mix in the Cosori Pro II and got a dome that was dark brown on top and slightly gummy in the center after 25 minutes at 325°F. A smart oven like the Breville with its bake mode gives you more even heat distribution and room for a proper 9-inch round pan.
How loud are air fryers and smart ovens during operation?
Air fryers are generally louder because they use a high-speed fan to circulate air in a small cavity. The Cosori Pro II measures about 52 decibels, the Ninja Foodi XL Pro hits 56 decibels, and the Breville Smart Oven Air Fryer Pro is quieter at 48 decibels but has a higher-pitched tone. For reference, a normal conversation is about 60 decibels, so neither appliance is disruptive, but the Breville is easier to ignore while watching TV or listening to a podcast.
Do smart ovens use more electricity than air fryers?
Yes, because they run longer. The Breville draws 1800 watts and typically runs 20–30% longer than an air fryer for the same food. For example, air frying 1.5 pounds of fries in the Cosori uses about 0.48 kWh (1700 watts × 16 minutes
