From Ninja’s earliest offerings (AF101) in 2018 to the now trendy Ninja Foodi SP series, the evolution of Ninja air fryers is remarkable. The models have the latest footprints in innovation, versatility, compactness, and enhanced cooking options. The Ninja Sp301 and SP351 are among the newest series and represent a significant milestone in Ninja’s air fryer evolution. They can use a pressure cooker, steam, air fry, grill, slow cook, etc.

Also, the SP351 is a touch control unit, whereas the 301 operates using knobs. Other features include 13 cooking programs, height, accessories, and dual heating technology, which are similar.

The SP351 is another distinctive Ninja Foodi appliance released on December 17, 2021. According to my exposition, it is an SP301 update. The unit has several features that are similar to those of its predecessor and also dissimilar. The similar ones include the 13-in-1 cooking functionalities, dimensions (15.33″ x 20.21″ x 8.15″ (DxWxH)), power (1800W), and dual heating technology. There are more, as the comparison chart above reveals. 

In this SP series, you will find unique features such as a temperature sensor or food probe (detachable). Such an item is a must-have in modern cooking. It eliminates the need to open your oven and check if your food is done and guesswork in cooking, which can cause serious illnesses. In addition, the food thermometer on this Ninja Foodi is digital/smart, meaning that it is customizable for alerts and precise. 

I like the SP351’s stainless steel body and brushed finish. The metallic body spells durability and long life. In addition, the unit is heat resistant, hygienic, and safe for use. It has no plastic emissions, which are toxic whenever you heat the Ninja Foodi. The brushed finish and the stainless-0steel combination are aesthetically appealing and durable.

Lastly, the gadget comes with touch controls. There are no knobs on the SP351, which makes it effortless to operate. Touch control gadgets are advantageous in that there are no moving parts. Damages are minimal, and cleaning up the smooth surface is easy. The unit is modern, sleek, initiative, and precise. Besides, knobs and dials take up space, especially in smaller kitchens or countertops.

Differences Between Ninja SP301 Vs SP351

When buying a Ninja SP series, note the following differences between the 301 and 351; 

  • Thermometer

One difference between the Ninja SP301 and SP351 that you won’t fail to notice is the food probe on the 351. This addition is crucial for measuring the progress of your food without opening the door. Once the food attains a certain temperature, it is certain that it is perfectly done and free from pathogens. Its texture, crustiness, and taste are perfect. So, the thermometer offers precision in cooking. 

  • Material

The two units come in different materials. Ninja SP301 is made of plastic, while the 351 is made of stainless steel. You can bet that the metallic unit is superior to the plastic one. It is durable, heat resistant, and doesn’t have plastic emissions or smell. 

  • Controls

Controls are the link between the user and the gadget. They enhance communication with the unit. For these two units, the sp351’s interface is touch while the 301 is knob controls. Each one of these has its pros and cons. The touch control on the SP351 is effortless to operate, precise, and fast to respond. Conversely, it is sensitive to dirt and moisture and more costly to replace. The knob controls are hardy but require some effort to dial and also harbors dirt on the grooves. 

  • Finish

If you love sleek designs, you will find both appliances worthwhile. However, the finishes are different. The 301 is stainless steel, whereas the 351 is brushed. Besides sleekness, another advantage of stainless steel is that it is easy to clean. A simple wipe leaves it shiny with no marks. The same applies to the brushed finish. It is an easy-to-clean finish that also does not stain or rust.  

Similarities Between Ninja SP301 Vs SP351

There are more similarities between the Ninja SP301 and SP351 than differences. As I said earlier, they are copy designs of each other with only a few contrasts. Have a look;

  • Dual Heat Technology

This heating technology is standard in both ninja appliances. It involves two heating elements on the unit to enhance different temperature settings. The elements work together for rapid heating precision and efficiency.

  • Rapid Cyclonic Heat

In both gadgets, powerful fans circulate hot air around the food. The circulation creates a cyclonic effect, enhancing even heat distribution and efficient cooking. Usually, the air is hot, and the speed is high, which cooks food without oil and crispiness.

  • Flip-And-Away Design

The flip-and-away design is essential for compact storage. Both units have the same design.

  • 1800W

The two SP Ninja Foodi series come with an 1800W power. 

  • Drop-Down Door Design

The most favorable door design in ovens is the drop-down. Its features include a door that opens downwards instead of sideways. The design provides easy access to the cooking chamber area and allows convenient loading and unloading. There are minimal risks of accidental burning or dropping of items.

  • Dimensions

These ovens have similar dimensions and measure 15.33″ x 20.21″ x 8.15″ (DxWxH).

  • 13 Cooking Programs

Each unit has 13 cooking options or programs, hence the 13-in-1 functionality. They include Reheat, Dehydrate, Bagel, Toast, Broil, Air Roast, Griddle, Fresh Pizza, Frozen Pizza, Bake, Rapid Bake, Sear Crisp, and Air Fry. 


There you have it! An ultimate guide between two air fryers with almost similar features, the Ninja SP301 and SP351, but different models. The Ninja SP351 has a temperature gauge, comprises stainless steel material, and has a brushed finish. It also has touch controls.

On the other hand, the Ninja SP301 has no thermometer, consists of plastic material, and has a stainless steel finish. Operations or controls are through knobs on the dashboard.
