When it comes to indoor grilling, having a versatile appliance that can sear, air fry, roast, and even dehydrate is a game-changer. I recently had the opportunity to test both the Ninja Foodi IG601 and IG651, and I was impressed by how much they can do in a compact countertop design.
Both models are designed for families or anyone who loves cooking indoors without sacrificing flavor. From juicy steaks to crispy fries and fluffy pancakes, these units promise a lot but what sets them apart? That’s what I wanted to find out.
Key Differences: Ninja IG601 vs IG651 Outdoor Grill
While the IG601 and IG651 share many features, there are a few key differences that influence which model might be right for you:
- Smart Thermometer: The IG651 comes with the Foodi Smart Thermometer, allowing precise control over doneness for proteins, whereas the IG601 does not include this feature.
- Technology & Controls: Both have 7 cooking functions, but the IG651’s smart integration makes temperature and doneness monitoring easier and more accurate.
- Price Point: The IG651 is slightly more expensive due to the added Smart Thermometer and advanced precision features.
- User Experience: With the IG651, I could cook steaks, chicken, and fish to perfection without repeatedly checking internal temperatures, which is a convenience the IG601 doesn’t offer.
In essence, if you value precise cooking and tech-assisted convenience, the IG651 is the clear choice. If you’re after solid performance and versatility at a slightly lower cost, the IG601 is more than capable.

Ninja Foodi IG601 vs IG651 Indoor Grill & Griddle Combo Review
If you’re looking for a powerful indoor grill that can do it all, I had the chance to test both the Ninja Foodi IG601 and IG651, and I want to share my hands-on experience. Both of these units combine a grill, griddle, and air fryer, but there are subtle differences that really affect daily cooking.
Design & Build Quality
From the moment I unboxed both units, I noticed their robust construction. The IG601 feels solid and professional, with a sleek black finish that suits any kitchen. The grill grate and flat-top griddle are thoughtfully designed, and the crisper basket fits perfectly for air frying.
The IG651 shares the same sturdy build but adds a Smart Thermometer, which gives a more modern, tech-forward feel. The control layout is intuitive on both models, and I loved the flexibility of cooking with the hood up or down. Overall, both feel like premium indoor grills, but the IG651 edges out slightly in versatility thanks to the thermometer integration.

Cooking Performance
Using the IG601, I was immediately impressed by the 500°F powered grill grate, which sears steaks beautifully and creates a delicious char without flare-ups. The flat-top griddle worked perfectly for pancakes, sandwiches, and even nachos. The air frying function gave up to 75% less fat while keeping fries and wings perfectly crisp. Cooking was even and consistent, with no cold spots.
With the IG651, I noticed similar performance on the grill and griddle. However, the Smart Thermometer truly elevated my experience. I could cook proteins to the exact doneness I wanted rare, medium, or well without guessing or repeatedly checking. For anyone who values precision, the IG651 delivers a noticeable advantage.
Ease of Use
Both units are straightforward to use. The IG601 is simple, plug-and-play, with clear temperature controls and straightforward settings for grill, air fry, roast, bake, broil, and dehydrate. Cleaning was a breeze; all removable parts are nonstick and dishwasher safe.

The IG651 adds the Smart Thermometer, which makes monitoring your food effortless. I loved not having to open the hood constantly to check internal temperatures. This feature is a game-changer for busy weeknights or entertaining guests. Otherwise, both models are equally user-friendly and don’t require advanced cooking skills to get professional results.
Cooking Functions
Both the IG601 and IG651 offer 7 cooking functions: Grill, BBQ Griddle, Air Crisp, Roast, Bake, Broil, and Dehydrate. This variety means I could prepare entire meals from appetizers to main courses without using multiple appliances.
The IG651’s Smart Thermometer adds 9 customizable doneness levels for proteins, which makes cooking meat more precise than ever. If you frequently cook steaks, chicken, or fish, the IG651 saves both time and stress. That said, for general grilling, air frying, and everyday meals, the IG601 performs excellently and may be all you need.
