The Ninja Crispi Portable Glass Air Fryer reimagines the air-fryer by replacing the usual basket with a glass tray that also serves as a plate. Designed for people who need a quick, clean cooking solution on the go, it offers a range of settings, including a “recrisp” mode that can revive pizza, noodles, and other leftovers.
Design and Functionality
The core idea behind the Crispi is simple: use a heat-shock-resistant borosilicate glass tray with a ceramic-coated inner layer. The heating element and fan sit in a hat-like unit that clamps onto the glass. When the tray is in place, the air circulates around the food just like a conventional air-fryer, but the glass also doubles as a serving dish.
Key Features
- Glass fryer tray: doubles as a serving plate, reducing cleanup.
- Heat-shock-resistant borosilicate: keeps the tray safe even after rapid temperature changes.
- Ceramic-coated trays: provide a non-stick surface for easy food release.
- Recrisp setting: re-cooks leftovers to a crispy finish.
- Bake setting: handles softer foods such as vegetables.
- Portable design: can be carried in a drawer or backpack if an outlet is nearby.
The heating element’s “fry” mode can reach temperatures that produce a crisp exterior, while the “bake” mode is gentler, making it versatile for a variety of foods.
Performance in Real-World Tests
A reviewer named Matthew Korfhage tested the Crispi in a variety of conditions, including freezing temperatures outside. The results were consistent:
- Crispy fries: achieved a crunchy texture even when cooked outdoors.
- Nuggets: came out golden and firm.
- Leftovers: pizza slices and noodle dishes returned to a nearly fresh state when used with the recrisp setting.

Korfhage noted that the glass tray insulated the food well during cooking, keeping the heat distributed evenly. The device’s temperature range was not as precise as some larger models, but it was adequate for everyday use.
Portability and Convenience
Because the tray is also a serving dish, users only need to wash a single glass piece instead of a full basket. This makes the Crispi a good fit for:
- Office lunches: leave it in a desk drawer and bring leftovers from home.
- Dorm rooms: a small footprint and minimal cleanup.
- Camping trips: as long as there is an outlet nearby, the unit can be used outdoors.
The trade-off is that the glass container is less precise in temperature control compared to larger air-fryers, and users may need to adjust their expectations for the exact cooking time.
Price and Color Options
The Crispi is available in several color families, each with a different price point. Below is a quick comparison:
| Color Family | Price | Size Options | Bundle Price |
|---|---|---|---|
| Cherry Crush, Frosted Lilac, Ginger Snap | $150 | Small, Medium, Large | $190 |
| Sage, Stone, Cyberspace Gray | $160 | Small, Medium, Large | $190 |
| Racing Green Bundle | – | All three sizes | $190 |
The pastel hues are the most affordable, while the more muted shades cost slightly more. The Racing Green Bundle offers all three tray sizes for a single price, which is useful for users who want to experiment with different portion sizes.
