How to Make Quick Meals with the Foodi SP351

The Ninja Foodi SP351 excels at preparing fast meals, especially when time is tight. Here are some practical ways to speed up your cooking:

Air Fry Frozen Food

Frozen foods like fries, chicken nuggets, and fish sticks cook evenly and quickly in the Foodi SP351. The air fryer function crisps the outside while keeping the inside tender.

Preheat the oven using the Air Fry setting.
Place frozen items on the included air fryer basket or tray.
Cook at the recommended temperature and time, usually 15-20 minutes for fries.
Shake or flip halfway through for even crisping.

Reheat Leftovers Without Drying

Reheating in the Foodi SP351 keeps food moist and tasty, unlike microwaves that can dry out meals.

Use the Reheat function or set the oven to 350°F.
Place leftovers on a baking tray.
Heat for 5-10 minutes depending on the portion size.
Use the built-in thermometer to check internal temperature for food safety.

Bake and Roast in Minutes

The convection fan circulates hot air, reducing cooking times for baked goods and roasted vegetables.

Use the Bake or Roast function.
Preheat the oven for best results.
Monitor cooking progress with the oven light and thermometer.

Making Perfect Fries with Less Oil

One of the most popular uses of the Ninja Foodi SP351 is making crispy fries with less oil. Traditional deep frying uses a lot of oil, but air frying cuts that down significantly.

Toss cut potatoes or frozen fries with 1-2 teaspoons of oil.
Spread fries in a single layer on the air fryer basket.
Cook at 400°F for 15-20 minutes.
Flip or shake halfway to ensure even cooking.

The result is fries that are crispy on the outside and soft inside, with up to 75% less oil than deep frying.

Using the Built-in Thermometer for Perfect Results

The Foodi SP351 includes a built-in thermometer that helps you cook meat and other dishes to the right temperature. This feature takes the guesswork out of cooking and improves food safety.

Insert the thermometer probe into the thickest part of the meat.
Set your desired internal temperature on the control panel.
The oven will alert you when the food reaches that temperature.

This is especially useful for roasting chicken, steak, or pork, ensuring juicy and perfectly cooked meals every time.

Exploring the Flip Away Oven Design

The Flip Away Oven design is a clever space-saving feature unique to the Ninja Foodi SP351. When you’re done cooking, the oven flips up and out of the way, freeing up valuable counter space.

Flip the oven up to store it compactly.
Flip it down to use the oven or air fryer functions.
The design makes cleaning easier since the interior is accessible from multiple angles.

This feature is ideal for small kitchens or anyone who wants to keep their countertop clear.

Dehydrate Snacks and More

Beyond frying and baking, the Foodi SP351 can dehydrate fruits, vegetables, and herbs. This function lets you make healthy snacks like dried apple chips or beef jerky at home.
