The first time I tested the Ninja Speedi and the Ninja Combi side-by-side, I wasn’t expecting such a dramatic difference between two appliances that promise nearly the same thing — fast, complete meals in a single machine. But after cooking everything from quick chicken-and-pasta dinners to slow-cooked stews and crispy snacks, the contrast became impossible to ignore. Both deliver speed, both deliver convenience, but they are built for very different types of kitchens and cooking habits.
The Speedi feels like a compact, fast little powerhouse designed for everyday meals for two to four people. The Combi, on the other hand, is a full-blown mini-oven + multicooker hybrid that leans heavily toward versatility, large capacity, and all-in-one functionality. If you’re torn between them, I’ll walk you through exactly how each model performed in my kitchen so you can clearly see which one fits YOUR cooking lifestyle.
Main Difference Between Ninja Speedi vs Ninja Combi Multicooker
The Ninja Speedi is designed for quick, one-touch meals in 15 minutes, making it ideal for small families and fast weeknight cooking.
The Ninja Combi is built for larger portions, more cooking functions (14 vs 10), and true all-in-one oven + multicooker performance, perfect for bigger families or anyone who wants one machine to replace multiple appliances.

Detailed Comparative Review
Before diving into each category, here’s a quick context, sweetheart — both units promise complete meals in 15 minutes, but they achieve it in different ways. The Speedi feels like a fast multi-tasker, while the Combi behaves like a countertop oven with smart steam infusion. Cooking the same dish in both was surprisingly revealing.
Design
Ninja Speedi
The Speedi has a compact, boxy design that fits comfortably on my counter without dominating it. Even though it carries a 6-quart capacity, it still feels manageable, especially when I’m working in a smaller kitchen setup.
The control panel is straightforward — everything sits neatly in a vertical layout, and switching between Rapid Cooker mode and Air Fry mode feels natural. The lid opens like a traditional air fryer, and the interior is deeper rather than wider. If you prefer appliances that don’t take up your entire workspace, the Speedi definitely scores points.
Ninja Combi
The Combi looks more like a mini-oven than a cooker. It’s wider, taller, and significantly heavier. The stainless steel finish gives it a premium presence, but you will need space for it.
Inside, the layout is flat and spacious — perfect for trays, large pieces of protein, or even a whole 6-lb chicken. The included Combi Pan, bake tray, and crisper tray make it feel like you’re working with an actual oven setup, but with steam and air circulation built in.
If you want something sleek and compact, the Speedi wins. If you want something impressive and substantial, the Combi stands out.

Ease of Use
Using the Ninja Speedi
Using the Speedi feels very “set it and forget it.” I literally pick my base (rice, pasta, veggies), place my protein, choose Speedi Meals mode, and it takes over. The SmartSwitch that toggles between Rapid Cooker and Air Fry modes eliminates guesswork.
For quick weeknight meals, this thing is a blessing. I found myself using the Speedi far more often on busy days because it’s fast and requires minimal thought.
Using the Ninja Combi
The Combi has more options, more trays, and more flexibility, but that also means a slightly steeper learning curve.
Functions like Combi Bake, Proof, Pizza, Toast, Rice/Pasta, and even Sous Vide make it feel like a true all-purpose machine. But you do need to familiarize yourself with when to use which tray and how different modes interact.
Once I got used to it, it felt incredibly powerful. But it’s not as grab-and-go as the Speedi.
For absolute simplicity, the Speedi takes the lead.
For advanced cooking options, the Combi is superior.

Functions & Performance
Speed and 15-Minute Meals
Both promise full meals in 15 minutes, so I tested identical dishes:
Chicken breast + pasta + broccoli
- Speedi: Finished in about 16 minutes. Moist chicken, steamed pasta, crisp topping.
- Combi: Finished in about 17 minutes. More even cooking, slightly juicier protein, better browning on top.
The Speedi is slightly faster.
The Combi is slightly better.

When cooking larger dinners (like roast chicken + veggies), the Combi is unquestionably better.

Conclusion & Recommendation:
After cooking with both models for a good amount of time, I realized that the right choice depends entirely on your household size and cooking style, not the raw features on paper.
If you want fast meals, simple operation, compact size, and everyday convenience, the Ninja Speedi is absolutely the better choice. I found myself reaching for it constantly when I needed something quick without thinking too much.
But if you want maximum versatility, a true all-in-one oven replacement, dishwasher-safe accessories, and larger capacity, then the Ninja Combi is the clear winner. It handled bigger meals, more complex recipes, and more cooking styles with ease.
My Personal Recommendation
- Choose the Ninja Speedi if you cook for 1–4 people and want fast meals with minimal effort.
- Choose the Ninja Combi if you cook for 4–8 people or want one appliance to replace several others.
Both are excellent — but they shine in very different kitchens.
