Testing outdoor gear usually involves a lot of heavy lifting and a trunk full of propane tanks, but the Ninja Woodfire series turned my deck into a high-end steakhouse with nothing more than a standard extension cord. I’ve spent the last several months rotating between the Ninja OG301 and the Ninja OG321, putting everything from 9-lb briskets to delicate air-fried asparagus through the wringer.
While most people see these as identical twins, there is a subtle but significant shift in how they handle “side dish” duty. These aren’t just grills; they are essentially outdoor convection ovens that happen to have a built-in smoke box. If you’re trying to decide if the extra settings on the OG321 are worth the countertop real estate, or if the OG301’s straightforward approach is enough for your weekend cookouts, here is my honest take from the grease-stained perspective of someone who has cooked over 100 meals on these machines.
The Key Difference: Ninja Woodfire OG301 vs. OG321 Electric Grill
The “chassis” of these two units is identical – same 1760 watts of power, same 141-square-inch cooking surface. The divergence is purely in the internal programming.
- The Ninja OG321 (The 6-in-1 Versatile): This model is the true “all-rounder.” It includes dedicated Air Fry and Broil While the OG301 can bake and roast, the OG321 is specifically tuned for high-velocity air circulation, allowing you to get that deep-fried crunch on wings or a high-heat sear on top of your dishes.
- The Ninja OG301 (The 4-in-1 Specialist): This is the focused version of the Woodfire family. It handles the “Big Four” – Grill, Smoke, Bake, and Roast. It lacks the specific Air Fry button, meaning it’s designed primarily for those who use their outdoor grill for traditional proteins and roasts rather than frozen snacks or crispy sides.

My Take: A Detailed Comparative Review
Design: Compact Powerhouses
The first thing I noticed when unboxing the OG301 was how dense it feels. At roughly 29 pounds, it’s not a toy. It feels like a piece of commercial kitchen equipment that has been weatherized. The footprint is small enough that I can fit it on a small balcony table, which is a massive win for apartment dwellers.
When I moved over to the OG321, I realized the design language is carbon-copied. Both have that satisfying “thud” when you close the lid and the same integrated side-mounted pellet smoker box. One design feature I’ve come to appreciate on both is the heat-resistant handle. Even when I was running a high-heat grill session at 500°F, I could lift the lid without reaching for a glove. The stainless steel and high-impact plastic build on both units has survived several surprise thunderstorms on my deck without showing a speck of rust.

Ease of Use: The “No-Flame” Factor
I’ve used propane grills for twenty years, and there’s always that split-second of anxiety when you’re clicking the igniter. With the OG301 and OG321, that’s gone. You plug them in, turn the dial, and you’re cooking.
The OG321 actually feels more intuitive for someone who is used to an indoor air fryer. Because it has the dedicated “Air Fry” button, I found myself using it for lunch more often – tossing in some frozen fries with a bit of “Woodfire” smoke turned them into something you’d get at a high-end gastro-pub. The OG301 is just as easy to operate, but it feels more like a dedicated “dinner” machine. You decide what you’re smoking or grilling, and you let it do its thing.
Both units feature a “Woodfire Flavor” button that you can toggle on or off. I’ve accidentally left it on for a cake once (not recommended), but for meat, it’s the most effortless way to add a smoke ring I’ve ever seen. You just dump a scoop of pellets in – no soaking, no timing, just pure flavor.
Functions: The Air Fryer Paradox
This is where the rubber meets the road. During my time with the OG301, I found myself “faking” an air fry session using the Roast function. It works okay because the fan is powerful, but it’s not quite the same. The Roast setting is designed for slower heat penetration, whereas Air Fry is about surface-level blast.
Using the OG321, the difference in the wings was undeniable. The dedicated Air Fry mode moves air at a higher velocity. I did a side-by-side test with 3 lbs of wings in each. The OG321 wings were noticeably crunchier and had rendered the fat more effectively in 20 minutes than the OG301 did on its Bake/Roast settings.
The Broil function on the OG321 is also a sneaky hero. If you’re doing a BBQ-sauced rack of ribs, you can use the smoker function for two hours, then hit “Broil” for the last three minutes to caramelize that sugar into a sticky, professional bark. You just can’t get that same top-down intensity on the 4-in-1 model.
Maintenance: Living with the Smoke
One thing no one tells you about pellet-infused electric grills is that smoke creates residue. After a few weeks with the OG301, the inside of the lid started to develop a “seasoning” – a dark patina of smoke and grease. This is normal, but you have to stay on top of it.
I found that the nonstick grill grates on both models are phenomenal. I’ve burnt honey-garlic marinade onto the OG321 grate until it looked like carbon, and it still wiped off after a 10-minute soak in the sink. The grease tray at the back is small, so you have to empty it every 2-3 cooks, or you’ll end up with a mess on your deck. Pro tip: Always use the disposable liners; cleaning that tiny tray by hand is the only part of this experience I didn’t enjoy.

Conclusion: Which Woodfire Wins the Weekend?
After living with both, the decision comes down to how you plan to use your outdoor space.
I recommend the Ninja OG301 if:
You already have a great air fryer in your kitchen and you just want an outdoor machine that can sear a steak and smoke a brisket. If you are a traditional “meat and potatoes” griller, the OG301 provides the core Woodfire experience without the extra cost for features you might not use. It is a robust, effective tool that does exactly what it says on the box.
I recommend the Ninja OG321 if:
You want to move your entire cooking operation outside during the summer. If you want to cook wings, fries, and jalapeño poppers while your main protein smokes, the OG321 is the superior choice. The Air Fry and Broil functions turn this from a “grill” into a “complete outdoor cooking system.” For me, the crispier wings and the ability to broil a crust onto my BBQ are well worth the extra investment.
My Personal Choice: I go with the Ninja OG321 every time. Being able to air fry a batch of smoky fries while I’m lounging on the deck is a luxury I didn’t realize I needed. It makes the machine feel like a more complete replacement for my indoor stove.
Frequently Asked Questions
Does the OG321 cook faster than the OG301?
In Grill and Smoke modes, they are identical. However, for things like wings or roasted potatoes, the OG321’s Air Fry mode is faster and more efficient at crisping than the OG301’s Bake or Roast modes.
Can I use liquid smoke instead of pellets?
You could, but you shouldn’t. The magic of the Ninja Woodfire is the combustion of real wood. Liquid smoke often has a chemical aftertaste. The 1/2 cup of pellets used in these machines provides a far more authentic BBQ flavor.
Do these grills produce a lot of smoke?
In “Smoker” mode, yes – it creates a significant, visible cloud of smoke for the first 10-15 minutes. In “Grill” mode with Woodfire tech on, it’s a lighter, more consistent stream. If you have very sensitive neighbors, keep the grill at least 10 feet away from their windows.
Can I use the OG301’s Roast setting to Air Fry?
Technically, yes, because both use a fan to move hot air. However, the fan speed on the OG321’s Air Fry setting is higher, meaning you get a much crispier exterior on your food compared to the Roast setting on the OG301.
Is the stainless steel version (OG321) harder to clean?
The outer material doesn’t affect the internal cleaning. Both have the same nonstick internal coating. A quick wipe with a microfiber cloth on the exterior keeps both looking sharp.
