Make fall meals for less

Give your range a break and use this small kitchen appliance to cook your family’s meals. Don’t let the compact size fool you. The double oven has everything you need to make a warm breakfast, lunch, and dinner for a family of two or more.

Not only will this Costco find help you make meals every day of the week, but you can also use it for parties and special occasions. Thanksgiving and Christmas are a few months away. If your current kitchen setup can’t handle the holiday menu prep, this affordable addition can make cooking for a larger group easy.

Whether you want a multi-tasking gadget that does more than just keep food warm or you’re short on space, the 14-in-1 buy is a home chef's helper that won’t break the bank. And unlike other appliances, you won’t have to pay extra for a contractor to hook up this oven.

Price: $199.99

This countertop appliance is much more than a basic toaster oven. The versatile Ninja product has 14 features, allowing you to toast, roast, bake, and more. You can make almost anything in either the top or bottom oven. And bonus, a family-sized capacity can handle a 12-inch pizza, six pounds of chicken wings, or an entire casserole.

The rapid-cook top oven bakes, broils, reheats, toasts, and keeps meals warm. But that’s not all. With this genius product, you won’t need a separate convection oven or air fryer. Air fry, convection bake, air roast, and dehydrate in the bottom oven section.

If space is a concern, you can eliminate an extra air fryer, toaster oven, or dehydrator from your appliance lineup. This all-in-one option easily fits on most kitchen counters and measures 18.6x16.39x13.26 inches.

What’s included?

Cook two completely separate meals, a side, and an entree, or an app and a dessert at the same time, once the Ninja Double Oven’s FlavorSeal Technology stops splashes, sprays, and scents from crossing between compartments.

Don’t worry about coordinating multiple items for one meal. Ninja’s Smart Finish tech syncs both ovens to one convenient cook time.

Each 18,000-watt double oven comes with two sheet pans, an air fryer basket, two wire racks, a roast pan, a Ninja NeverStick Premium nine-inch round cake pan, a Ninja NeverStick Premium eight-inch square cake pan, and a removable crumb tray.

You will also get a handy recipe guide. So, if you’re unsure what to make for dinner, need an ingredient list for a holiday side, or just want a few easy ideas, you won’t need to spend extra on a separate book.

Costco’s deal beats all others

Does the multi-use toaster, pizza maker, convection oven, and air fryer seem like a splurge?

Before you let sticker shock guide your decision-making process, consider what other products cost. Costco sells this Ninja double oven for under $200. Compare the $199.99 price tag to $329.99 at Kohl’s or Target. And don’t assume online prices are better than what you could pay at a brick-and-mortar store. Amazon’s list price for the double-door oven is also $329.99.

Along with saving money at Costco on this item compared to the price tag at other retailers, the combination of products in this Ninja Double Door model makes it an affordable alternative.

You could pay almost $500 for a stainless steel Breville Joule Oven Air Fryer Pro at Williams Sonoma just to get similar features. A Power XL eight-quart air fryer retails for $119 at Walmart. While this is lower than the Ninja’s price, you won’t be able to bake, toast, or roast in the appliance, much less work on two separate meals at the same time.

Bottom line

While you can find serious savings on groceries, baking staples, and frozen foods, the members-only club also has a can’t-beat deal on a Ninja Double Oven to cook these items with.

Costo's price tag will save you money compared to what you could pay for the same appliance at other superstores.
