Ninja DZ550 vs DZ401: My Honest Take After Hands-On Testing

When I first looked at the Ninja DZ550 and DZ401, I knew choosing between them wouldn’t be simple. Both have great features and get the job done. Still, each has its own edge. The DZ550 offers smart tools and better control. The DZ401 keeps things simple and is easier on the wallet. 

I’ve tested both in my own kitchen, from fast meals to full dinners. In this review, I’ll walk you through the ups and downs of each. That way, you can pick what fits your needs and cooking style best. 

Is Ninja DZ550 Good?

I’ve been using the Ninja DZ550 every day for over a week, and it’s made cooking much easier. I can cook dinner in less time, with less mess. The two baskets let me make a full meal at once—no waiting, no stress. Food comes out crisp, juicy, and tastes great without much oil.

It has a 10-quart size, 1690 watts of power, and 6 cooking programs that are easy to use. The Smart Finish function helps both baskets finish at the same time. The built-in Smart Thermometer makes sure meat is cooked just right. If you want fast, simple meals with less cleanup, the Ninja DZ550 is a smart choice.

What I Like

After using the Ninja DZ550 every day for over a week, I can say it’s now one of the top tools in my kitchen. Whether it’s dinner for the family or a fast lunch, it’s quick, easy, and makes food taste great. Here’s what I like most:

• Dual Zone technology makes cooking simple. I can cook two foods at once. Chicken goes in one basket, potatoes in the other. No waiting. No need to switch things around.
• Smart Finish function is a time-saver. This feature lets both baskets finish at the same time. Even if they have different foods and cook times. It’s like having someone else help in the kitchen.
• IQ Boost cooks fast and evenly.  I’ve noticed the IQ Boost cooking technology really does speed things up. It gives even results and keeps things from drying out. From frozen fish to roasted veggies, everything comes out crispy outside, soft inside.
• Big capacity without feeling bulky.  With a 10 quart air fryer large capacity, it’s great for our family of four—and even more if we have guests. It doesn’t feel overwhelming on the counter either, which surprised me.
• Dishwasher safe baskets = easy cleanup. The baskets and crisper plates are dishwasher safe. That means no scrubbing. Even cheese wipes off fast.
• Independent 5 qt baskets give you options. Some days I use both baskets; other days just one. Having two separate zones gives me flexibility without waste.
• Perfect for small treats too.  Beyond dinner, I’ve made frozen croissants and even a giant cookie. The bake function works like a charm—flaky, warm, and done in 10 minutes.
• Temperature range is great for everything. I love that I can air fry at 400°F or dehydrate at 105°F. It gives me a wide range to experiment, and it’s helped cut down on oven use.

What Could Be Better

While I’ve really enjoyed using the Ninja DZ550, there are a couple of things that took me some time to get used to. These aren’t deal breakers at all—just little things that could be better with experience or small tweaks. I still highly recommend it!

• Takes a little practice at first. If you’re new to air fryers (like we were), the cooking times might surprise you. Things cook faster, and sometimes need less time than what the package says. But after a few tries, you’ll get the hang of it.
• Thicker foods may need flipping.  When we made chicken with the skin on, we started skin-side down. Halfway through, we flipped it and the skin got much crispier. Just something to remember—placement matters!
• Slight learning curve with baking.  Our first attempt at baking cookie dough was slightly overdone, even after reducing the time. It’s powerful, so I’d recommend starting low and working up.
• A bit bulky for small counters.  The air fryer isn’t huge, but it does take up some counter space. If you have a smaller kitchen, make sure you measure before buying.

Recommendation

If you want fast and simple meals, the Ninja Foodi Max Dual Zone air fryer (DZ550) is a great pick. It works well for busy families or anyone who cooks often. You can make two foods at once, which saves time. The Smart Finish function helps both baskets finish cooking together. 

The built-in Smart Thermometer takes out the guesswork with meat. It has 6 cooking programs, so you can fry, bake, roast, or reheat with ease. Cleanup is quick, and the baskets are easy to wash. It takes up some space, but for what it can do, I think it’s worth it.

Is Ninja DZ401 Good?

The Ninja DZ401 has made my daily cooking much easier. I can cook two foods at once, and both finish at the same time. The food comes out crisp with little oil. Clean-up is fast, which helps a lot after dinner.

This air fryer has two 5-quart baskets, 6 cooking functions, and 1690 watts of power. The DualZone Technology and dual heating element cook food fast and even. It works well for busy people and small kitchens. For me, it saves time and makes meals simple.

What I Like

After using the Ninja DZ401 for several weeks in my own kitchen, I’ve found some clear standouts that make this dual-basket air fryer more than just a countertop gadget. These are the reasons I keep coming back to it meal after meal.

• I Can Cook Two Things at the Same Time
  I put fries in one basket and fish sticks in the other. They both finish together. The Smart Finish button makes it easy.
• Match Cook Makes Big Meals Easy
  I often cook wings in both baskets. With Match Cook, I set it once and both sides cook the same way. It saves me time.
• Even Cooking, Every Time
  Each side has its own heater and fan. That means food cooks well on both sides. Fries come out crisp. Chicken cooks all the way through.
• Easy to Clean Crisper Plates
  The non stick crisper plates and baskets go in the dishwasher. No hard scrubbing. Food slides right off.
• Fast Dinners on Busy Days
  When I’m in a rush, I toss in frozen foods. No preheat needed. Press a few buttons, and dinner is done in 15–20 minutes.
• Built Well and Simple to Use
  It feels strong and works every time. The buttons and dial are clear. Even my partner uses it without asking for help.
• Healthier Than Deep Frying
  I use little to no oil. Food still comes out crisp. I eat better and feel better too.

What Could Be Better

The Ninja DZ401 is great, but it’s not perfect. Here are a few small things that could be better. These are not big issues for me, but good to know.

• Takes Up Space on My Counter
  It’s big. That makes sense—it holds a lot of food. But if your counter is small, check the size first.
• No Safety Lock for Empty Baskets
  You can turn it on with no basket inside. I don’t have kids, so it’s not a problem. But if you do, keep an eye on that.
• Only One Side Reaches 450°F
  The Air Broil mode hits 450°F, but only on one side. It still works well for me, but it’s worth noting.
• Not Many Presets
  I use the manual settings most of the time. Still, more presets for foods like nuggets or veggies would help.

Recommendation

If you want to save time in the kitchen, the Ninja dual-compartment fryer is a great choice. You can cook two foods at once with its DualZone Technology. I like how simple it is to use, even on busy days. 

The 10-quart air fryer holds a lot, so it works well for families. Food comes out crisp, thanks to the dual heating element, and it needs little oil. Clean-up is fast, and both baskets go in the dishwasher. It is a bit big, so check your counter space first. But for me, it’s made dinner easier and faster.
