Understanding the 13 Functions of the Ninja 13 in 1 Air Fryer
The first step to using any multifunction cooker is knowing what each setting actually does. The ninja 13 in 1 air fryer includes programs for air fry, air roast, bake, whole roast, broil, toast, bagel, dehydrate, reheat, and more. Each function adjusts the fan speed, heating element intensity, and cooking time automatically.
For example, the air fry setting uses high fan speed and top heat to create crispy exteriors. The bake setting turns off the fan and relies on bottom heat, mimicking a traditional oven. If you select whole roast, the machine cycles heat from all sides to cook larger items evenly.
Air Fry
Use this for frozen fries, chicken wings, and breaded items. Set the temperature between 375°F and 400°F. Cook times range from 12 to 20 minutes depending on thickness. Shake the basket halfway through for even browning. The crisper plate allows excess oil to drip away.
Air Roast
This function combines fan and bottom heat for vegetables and meat. It works well for roasted potatoes, broccoli, and chicken thighs. Temperature range is 350°F to 400°F. Roast vegetables for 15 to 25 minutes, flipping once.
Bake
No fan, bottom heat only. Perfect for cookies, brownies, and small casseroles. Use the included sheet pan or a metal baking dish. Preheat for 3 minutes before adding batter. Typical bake time for cookies is 8 to 12 minutes at 350°F.
Whole Roast
Designed for whole chickens, roasts, and large cuts of meat. The machine adjusts heat distribution to cook the center without burning the outside. For a 4-pound chicken, roast at 375°F for 45 to 55 minutes. Let it rest 10 minutes before carving.
Broil
High top heat for melting cheese, browning casseroles, or finishing steaks. Preheat for 2 minutes, then cook for 3 to 6 minutes. Watch closely—broil can burn food quickly.
Toast
Uses top and bottom heat with a timer. Bread toasts in 3 to 5 minutes depending on thickness. The shade selector lets you choose light, medium, or dark.
Bagel
Similar to toast but heats only the top element. This toasts the cut side of the bagel while leaving the outer crust soft. Bagels take 4 to 6 minutes.
Dehydrate
Low heat and continuous fan circulation. Set temperature between 125°F and 165°F. Thinly slice fruits, vegetables, or jerky and arrange in a single layer. Dehydrating time varies from 4 to 12 hours depending on moisture content. Check periodically.
Reheat
Uses moderate heat and fan to warm food without drying it out. Ideal for pizza, fried chicken, and casseroles. Reheat at 300°F for 3 to 8 minutes.
Setting Up Your Ninja 13 in 1 Air Fryer for First Use
Before cooking anything, remove all packaging materials. The appliance ships with a crisper plate, sheet pan, and sometimes a rack depending on the model. Wash these parts in warm soapy water with a non-abrasive sponge. Rinse and dry completely.
Place the unit on a flat, heat-resistant surface with at least 5 inches of clearance on all sides. Do not put it under cabinets or near curtains. The exhaust vent at the back releases hot air and steam.
Run an empty preheat cycle at 400°F for 10 minutes to burn off any manufacturing residues. This is normal—you might smell a light odor. Open a window. After cooling, wipe the interior with a damp cloth.
Choosing the Right Pan and Accessories
The ninja 13 in 1 air fryer works best with metal or silicone accessories. Avoid glass or ceramic pans unless they are specifically labeled oven-safe to 450°F. Sudden temperature changes can crack glass. Use the included crisper plate for air frying, the sheet pan for baking, and a metal rack for roasting.
If you need additional pans, check the dimensions of your model. Most 13-in-1 units have a 10-quart capacity with a cooking area roughly 13 by 13 inches. Round pans should not exceed 10 inches in diameter. For more details on compatible accessories, our The Best Ninja Foodi 9 in 1 Air Fryer of 2026 guide covers the pans and racks that fit multiple Ninja models.
Cooking Techniques for Best Results with the Ninja 13 in 1 Air Fryer
Getting consistent results means understanding how heat and airflow behave inside this appliance. Unlike a full-size oven, the heating elements are close to the food. This means faster cooking but also a higher risk of burning if you walk away.
Always preheat for air frying and baking unless the recipe says otherwise. The preheat cycle typically runs for 3 to 5 minutes. Adding food to a cold machine extends cooking time and can lead to soggy textures.
Air Frying Frozen Foods
Frozen french fries, onion rings, and chicken nuggets cook directly from frozen. Do not thaw. Set the temperature 25°F lower than the package instructions for a conventional oven. Cook for 15 to 20 minutes, shaking the basket every 5 minutes. The ninja 13 in 1 air fryer circulates air so effectively that you often need less oil than traditional methods. A light spray of avocado oil helps browning.
Roasting Vegetables
Cut vegetables into uniform 1-inch pieces. Toss with oil, salt, and pepper. Spread in a single layer on the sheet pan—crowding leads to steaming instead of roasting. Roast at 375°F for 15 to 20 minutes. Broccoli florets take 12 minutes; Brussels sprouts take 18 minutes. Flip halfway through.
Baking and Desserts
Use the bake function for cookies, muffins, and small cakes. Line the sheet pan with parchment. Bake at 325°F to 350°F. Check doneness 2 minutes before the recipe’s suggested time because the smaller cooking chamber transfers heat faster. For brownies, use an 8-inch metal pan placed on the rack.
Cooking Meat and Poultry
For chicken breasts, pound them to even thickness first. Season and air fry at 375°F for 12 to 15 minutes. Use a meat thermometer to confirm an internal temperature of 165°F. For steak, preheat on air fry setting at 400°F, then cook for 8 to 12 minutes depending on desired doneness. Let steak rest 5 minutes before slicing.
For larger roasts, the whole roast function is ideal. Season a 3-pound pork loin and cook at 375°F for 35 to 45 minutes. Allow resting time. The even heat distribution prevents the outside from drying before the center reaches safe temperature.
Dehydrating for Snacks and Cocktail Garnishes
As a mixologist, I use the dehydrate function regularly for citrus wheels, herb garnishes, and fruit chips. Slice oranges or lemons paper-thin, about 1/8 inch. Arrange in a single layer on the crisper plate. Set temperature to 135°F and dehydrate for 6 to 8 hours. The result is a chewy, translucent garnish that adds visual appeal to drinks without diluting them.
For jerky, use lean beef sliced against the grain. Marinate for 4 hours, pat dry, and lay strips without overlapping. Dehydrate at 160°F for 4 to 6 hours. Store in an airtight container.
Cleaning and Maintenance of Your Ninja 13 in 1 Air Fryer
Regular cleaning prevents smoke, off flavors, and bacterial buildup. After every use, allow the appliance to cool completely. Remove the crisper plate and pan. Wash them in hot soapy water with a non-abrasive sponge. The nonstick coating scratches easily—avoid steel wool or harsh scrubbers.
The heating element and interior walls can accumulate grease splatter. Once a week, wipe the interior with a damp microfiber cloth. For stubborn residue, mix a paste of baking soda and water, apply it to the affected area, let it sit for 10 minutes, then wipe clean.
The exterior should be wiped with a soft damp cloth. Do not use abrasive cleaners or spray liquids directly onto the control panel. The exhaust vent at the back can be vacuumed gently with a brush attachment to remove dust.
Deep Cleaning the Heating Element
If you notice smoke during preheating or cooking, grease might be trapped on the heating element. Unplug the machine. Use a cotton swab dipped in rubbing alcohol to gently wipe the exposed coils. Do not bend or damage the element. Allow the alcohol to evaporate completely before using the appliance again.
Replacing the Crisper Plate
With regular use, the nonstick coating on the crisper plate may wear after 18 to 24 months. You can order a replacement directly from Ninja or from authorized retailers. Look for a plate that matches your specific model number, which is printed on the back or bottom of the unit.
Common Mistakes and How to Avoid Them
Even experienced cooks make errors with multifunction air fryers. The most frequent problem is overfilling the basket or pan. Air needs to circulate around every piece of food. If you crowd the pan, you get uneven cooking and soggy results. Cook in batches if necessary.
Another mistake is ignoring the preheat. Many people skip preheating to save time, but this adds 5 to 10 minutes to the total cook time and produces less crispy food. Set a timer for preheat and add food only when the machine signals it is ready.
Using the wrong function for the task also causes issues. For example, using air fry setting for a cake will blow the batter around and create a mess. Stick to bake for baked goods and air fry for crispy items. The The Complete Ninja Foodi 8 Qt Air Fryer Guide includes a function comparison table that applies to the 13-in-1 model as well.
Frequently Asked Questions
Can I use aluminum foil in the ninja 13 in 1 air fryer?
Yes, but with caution. Place foil only on the crisper plate or sheet pan, and ensure it does not touch the heating element. Weigh it down with food so the fan does not blow it around. Do not line the entire basket with foil because it blocks airflow. For best results, use foil only to wrap potatoes or vegetables.
How do I clean the inside of the ninja 13 in 1 air fryer?
After the unit cools, wipe the interior with a damp cloth or sponge. For baked-on grease, use a paste of baking soda and water applied with a soft brush. Never use metal scouring pads or abrasive cleaners that scratch the nonstick surface. The heating element can be gently wiped with a cotton swab dipped in rubbing alcohol if needed.
What is the difference between air fry and air roast on the ninja 13 in 1 air fryer?
Air fry uses high fan speed and top heat for fast, crispy cooking of smaller items like fries and wings. Air roast combines fan circulation with bottom heat, making it better for larger items like vegetables and meat that need more even cooking. Air roast cooks at slightly lower fan speeds and is gentler on delicate foods.
