The Instant Omni Plus 19QT is the largest and most capable countertop oven in the Instant lineup. Designed for families, batch cooking, or those who want to replace their traditional oven, it offers exceptional interior space paired with Instant’s signature EvenCrisp™ technology. Whether you’re roasting a whole chicken, cooking two pizzas, or air frying large batches of food, this unit feels built for serious home cooks.
Massive Capacity (10/10)
If capacity is a priority, this is one of the best models you can buy. It fits:
- 2× 12-inch pizzas
- A whole chicken (rotisserie included)
- 6–9 slices of toast
- Large baking sheets
This makes it ideal for meal prep, large families, and entertaining.
Cooking Performance
The Omni Plus uses Instant’s EvenCrisp™ technology, delivering consistent air circulation that produces crispy, evenly cooked results. Compared to standard convection ovens, the airflow here is stronger and more targeted.
In real-world use, it performs extremely well with:
- Fries and frozen snacks
- Whole rotisserie chicken
- Baked desserts
- Roasted vegetables
- Pizzas and flatbreads
Built-in Rotisserie
This is one of the Omni Plus’s best features. Rotisserie chicken comes out juicy with perfectly crispy skin, and the included rotisserie spit is easy to mount and remove. Very few air fryer ovens at this price offer a rotisserie, and Instant’s implementation is one of the better ones.
