Do you need to preheat Ninja Foodi?

The Ninja Foodi is an innovative multi-cooker that can pressure cook, air fry, bake, broil, dehydrate, and more. With so many cooking functions, one common question is whether you need to preheat the Ninja Foodi before cooking.

The short answer is that it depends on what you are cooking and the specific model of Ninja Foodi you have. Some recipes may require preheating while others do not need it. Ninja Foodi models that have air frying capabilities often recommend preheating for best results.

In this article, we’ll provide a detailed look at preheating recommendations for different models of the Ninja Foodi and cooking functions. We’ll also share tips on how to tell if your specific recipe needs preheating or not.

Do You Need to Preheat the Ninja Foodi for Pressure Cooking?

One of the main functions of the Ninja Foodi is pressure cooking. The pressure cooking setting allows food to cook very quickly by building up steam inside the sealed pot.

For pressure cooking, you do not need to preheat the Ninja Foodi. Here are some key points on preheating for pressure cooking:

– The pressure cooking function brings the pot up to temperature very quickly on its own. Preheating is not necessary.

– Ninja Foodi pressure cooking recipes do not recommend preheating the unit. You can add your ingredients and liquid to the pot and start pressure cooking right away.

– Preheating would not significantly speed up pressure cooking or affect the results. The pressurized environment is what cooks food fast, not added heat from preheating.

– Some users report preheating the unit before pressure cooking can cause the pot to pressurize too quickly. It’s better to allow the pot to build pressure gradually after adding your ingredients.

So for pressure cooking, starting the cooking process without preheating is recommended by Ninja and generally not necessary. The pressure cooking function will bring the Ninja Foodi pot up to the right cooking temperature very quickly on its own.

Do You Need to Preheat the Ninja Foodi for Air Frying?

For Ninja Foodi models that have air frying capabilities, preheating is often recommended for best results when air frying. Here are some tips on preheating for air frying in the Ninja Foodi:

– Ninja official air fryer recipes almost always instruct you to preheat the Foodi before adding food for air frying.

– Preheating helps the air frying function mimic a real convection oven. Preheating gets the cooking chamber hot which is important for crisping the exterior of foods.

– A preheated air fryer can help food cook faster and more evenly. The initial blast of hot air seals in moisture.

– If you don’t preheat, food may come out more greasy and less crispy. Preheating dries out the interior of the cooking chamber.

– The time needed to preheat varies based on the amount of food but is usually between 3-5 minutes. Ninja recommends preheating for 5 minutes for optimal heat.

– After preheating, the unit will beep and the heat indicator light will turn off indicating it’s ready for cooking.

So for the air fry function, preheating the Ninja Foodi is strongly recommended for crisper, less greasy, evenly cooked foods. Be sure to consult official Ninja Foodi air fryer recipes for exact preheat times.

Do You Need to Preheat for Other Functions Like Bake/Roast, Broil, or Dehydrate?

In addition to pressure cooking and air frying, some Ninja Foodi models offer other functions like bake/roast, broil, and dehydrate. Here are preheating recommendations for these other cooking functions:


– Preheating is recommended when using the bake/roast function to mimic a traditional oven.

– Preheating helps prevent loss of heat when food is first added. It gets the pot uniformly hot first.

– The Ninja manual states preheating for 5-15 minutes on bake/roast, depending on amount of food.

– After preheating, add food immediately once the unit beeps to prevent heat loss.


– Preheating is required when broiling in the Ninja Foodi.

– The unit must fully preheat before broiling to create the high heat needed to brown/char food.

– Broiling preheat tends to take 10-15 minutes. The manual provides exact times based on food amount.

– Pay attention as broiling preheat times are longer than for other functions.


– You do not need to preheat when using the dehydrate function.

– Adding food right away is recommended as dehydrate relies on air circulation, not preheated heat.

– Preheating could cause faster drying of the exterior before the inside is dehydrated.

So for bake/roast and broil, preheating is recommended by Ninja for best results. For dehydrate, preheating is not needed. Check your model’s user manual for exact preheat times.

How to Tell if Your Specific Recipe Needs Preheating

When reviewing Ninja Foodi recipes, the instructions will specify whether preheating is required for that particular food based on function used and cook time. However, if you are adapting a non-Ninja recipe or creating your own, here are some tips on determining if you should preheat:

– If air frying foods that need a crispy exterior like fries, chicken wings, etc., always preheat to crisp the outside.

– Preheating is not needed for quick pressure cooking recipes under 15 minutes.

– Preheat for meat roasts, whole chickens, breads, and baked goods that require a hotter starting environment.

– Don’t preheat if simmering stocks, boiling water, steaming vegetables, or other liquid-based pressure cooks.

– For broiling, you must always preheat thoroughly before adding food.

– If baking delicate souffles, custards or casseroles, preheating helps prevent the dish from collapsing.

– Preheating is not necessary when slow cooking or braising meats for longer periods.

Getting to know your model’s capabilities and learning what each cooking function requires will help you determine when preheating is recommended or not. Both the Foodi’s cooking ability used and the properties of what you are cooking factor in.

Tips for Preheating the Ninja Foodi

Here are some useful tips for preheating your Ninja Foodi to get ideal results:

– Always preheat with the cook pot or fryer basket in place, not empty.

– Close the lid during preheating. Opening repeatedly lets heat escape.

– For air frying or baking, use cooking spray or oil before preheating for best heat conduction.

– Preheat for the full recommended time in your manual, don’t cut it short.

– Have ingredients ready to load immediately once preheated to minimize heat loss.

– Avoid overcrowding when cooking in a preheated Foodi. This can lower the temperature.

– If preheating multiple batches, allow the Foodi to reheat fully in between.

Following these best practices when preheating the various functions will allow your Ninja Foodi to produce crispy, evenly cooked foods just like a traditional oven.


Knowing whether or not your Ninja Foodi requires preheating depends on several factors like:

– The specific cooking function used – air fry must be preheated, but not pressure cook.

– The recommended preheat times for your particular Ninja Foodi model.

– The type of food being cooked – meats, fried foods, and baked goods need preheat.

– The total cook time – longer cooks may not need preheat.

By consulting your official recipe instructions and manual, you can determine when preheating is required to get the very best results. While not strictly necessary for all functions, preheating helps mimic traditional cooking methods. With the proper preheating, your Ninja Foodi can achieve crispy fried dishes, perfectly browned roasts, and consistent baking.
