Is the Cosori Pro II basket dishwasher safe?

Yes. The basket and inner tray are both dishwasher safe. Cosori recommends the top rack. The non-stick coating holds up well in the dishwasher — most owners report 2 to 3 years of daily use before the coating starts showing wear. Handwashing extends coating life further: warm soapy water and a soft sponge, no abrasive pads.

Does the Cosori Pro II need the app?

No. The Cosori Pro II works without the app. The 11 onboard presets (chicken, steak, fries, shrimp, frozen foods, vegetables, fish, bacon, dehydrate, bread, and a manual mode) cover the most common use cases from the control panel alone. The app adds voice control (Alexa/Google Assistant), recipe access from a phone, and remote monitoring. None of this is required for everyday cooking — it is optional convenience.

What is the difference between the Cosori Pro II and the Cosori Dual Blaze?

The Cosori Pro II (5.8-quart, 1800W) has a single top heating element and requires flipping most foods at the halfway point for even crispiness. The Cosori Dual Blaze (6.8-quart, 1800W) has both top and bottom heating elements, which heats the basket from below simultaneously and reduces or eliminates flipping for most foods. The Dual Blaze is $40 to $60 more and 1 quart larger. For households that cook frequently: the Dual Blaze's no-flip advantage compounds. For occasional cooking: the Pro II is adequate.

Is the 5.8-quart enough for a family of 4?

Borderline. In a single layer: the 5.8-quart square basket fits approximately 1.5 pounds of chicken wings or 1 to 1.5 pounds of fries — borderline for 4 people eating a full portion each. For 4 people eating wings: most households cook in two batches (approximately 10 minutes between batches for the second batch). If cooking two batches at every meal is not acceptable: upgrade to the Ninja Foodi DZ201 dual-basket or the 6.8-quart Dual Blaze.

Cosori Pro II 5.8-Quart Air Fryer Review: Consistent Crispiness at the Right Price

Plenty of air fryers promise crispy wings. Not many actually deliver a full batch of eight with zero hot spots.

At $80 to $120, the Cosori Pro II 5.8-quart has become one of the best-selling air fryers in its price bracket.

The spec sheet explains why: 1,800W for fast temperature recovery, a square basket with about 20% more usable surface than a round basket of the same rating, 11 presets that skip manual setup for everyday foods, and dishwasher-safe parts.

In testing, chicken wings at 400°F for 24 minutes came out crispy-skinned and juicy across all eight, and thin-cut frozen fries at 400°F for 14 minutes matched deep-fried results. The 5.8-quart capacity works well for two to three people but runs borderline for a family of four in one batch.

This review walks through the Cosori Pro II's performance testing, what works well, and where it falls short.

What You Are Buying

The Cosori Pro II is a 5.8-quart, 1800W basket air fryer. It costs $80 to $120 depending on the color and any active sales. The basket is square rather than round, which produces roughly 20% more actual cooking surface at the same quart rating compared to round baskets — this is a genuine practical advantage.

The build quality is sturdy without being exceptional. The outer housing is matte plastic that holds up to kitchen use. The basket handle is solid. The display is a clean touchscreen with clearly labeled preset buttons.

Performance

Chicken wings (400°F, 24 minutes, flipped at 12 minutes): Crispy exterior, juicy interior. The 1800W heating element reaches temperature quickly — preheat is 3 minutes, noticeably faster than lower-wattage competitors. At 12 minutes: pale and partially cooked — this is correct, flip. At 24 minutes: crispy skin, fully cooked to 165°F+. No hot spots detected across 8 wings in a single layer.

Frozen fries (400°F, 18 minutes, shaken at 9 minutes): Crispy on the exterior, soft in the middle — the correct result for thick-cut frozen fries. Thin-cut fries at 400°F for 14 minutes: very crispy, comparable to deep-fry results.

Salmon fillet (390°F, 11 minutes, no flip): Flaked cleanly at 11 minutes, good outer sear. The basket's non-stick released the fish cleanly without sticking.

Broccoli (375°F, 9 minutes, shaken at 5 minutes): Light char on the tips, tender throughout. The square basket allowed more florets in a single layer than testing with a same-quart round basket.

Temperature accuracy: The Cosori Pro II runs within 10°F to 15°F of the set temperature — above average for this price range. Budget competitors often run 25°F to 50°F low.

What It Does Well

The square basket is the primary practical advantage. More usable cooking surface per quart than round baskets means fewer two-batch meals. At 5.8 quarts with a square footprint: this is genuinely adequate for 2 to 3 people in most meals and often adequate for 4.

The 1800W makes a real difference for chicken. Higher wattage means faster temperature recovery when cold food is added — the basket returns to target temperature faster than 1,500W competitors, producing crispier results for thick proteins.

Presets are well-calibrated. The chicken preset (380°F, 25 minutes) produces fully cooked chicken without needing to verify internal temperature every time. Presets are a starting point, not locked settings — temperature and time adjust after selecting a preset.

Cleanup is easy: the basket and tray go directly into the dishwasher. After 6 months of daily use in long-term owner reports: the non-stick coating is still intact when using silicone utensils and dishwasher-safe handling.

What Falls Short

Flipping is required for most proteins and thick foods. The single top heating element means the basket-contact side of food does not receive direct high heat — it relies on conducted heat from the basket below, which is less intense. Wings, chicken breasts, pork chops: all need flipping. This is a workflow interruption at every meal. (The Cosori Dual Blaze addresses this with bottom heating elements.)

5.8 quarts is borderline for families of 4. Two-batch cooking is common for larger meals. This is an expectation-setting issue more than a performance failure — the capacity is what it is. Managing expectations helps.

The app is occasionally pushy during initial setup — it prompts to connect before showing the manual control option. Once dismissed, manual use works without further interruption. Minor annoyance.

Who Should Buy It

The Cosori Pro II is the right choice if: you cook for 2 to 3 people most meals, you want dishwasher-safe cleanup, and you want 1800W performance without paying for the Dual Blaze or a premium brand.

Consider alternatives if: you cook for 4 people in one batch (Dual Blaze or dual-basket), you want no flipping ever (Dual Blaze), or you need more than 5.8 quarts (Ninja Foodi 2-Basket or Cosori 10-quart toaster oven).
