Our Buying Assessment
The Ninja FlexFlame PG301BK is an unusually versatile outdoor cooking system that combines propane grilling with electric-powered convection and smoke infusion. That makes it particularly interesting for households that want several cooking methods without owning several separate appliances.
Its biggest compromises are its premium positioning, dependence on electricity, audible convection fan and the fact that independent testing has found its smoking function less convincing than its grilling and roasting performance.
Who it's for:
- Outdoor cooks who want one system for grilling, roasting, smoking, griddling and pizza.
- Families who regularly cook larger meals outdoors.
- Buyers who value precise temperature control and convection-style cooking.
- People who would rather consolidate several outdoor cooking appliances.
Who should skip it:
- Traditionalists who want a simple propane grill that works without electricity.
- Dedicated barbecue enthusiasts primarily interested in deep, sustained smoke flavor.
- Buyers who want a particularly quiet outdoor cooking appliance.
- Anyone shopping strictly on initial price rather than versatility.

What Is the Ninja FlexFlame PG301BK?
The FlexFlame is Ninja's attempt to combine several outdoor cooking technologies into one full-size cooking station. The PG301BK provides five advertised cooking functions: grill, smoke, roast, griddle and pizza.
Unlike a conventional propane barbecue, it uses both liquid propane and electricity. Propane supplies the primary cooking heat while electricity powers the digital controls and high-velocity convection system.
Ninja specifies a 20-pound propane tank and an outdoor-rated three-prong extension cord. These are not included with the grill.
The result is a different cooking experience from a traditional gas grill: instead of relying only on burner heat, the FlexFlame circulates heated air around the food to promote faster and more even cooking.

The Big Idea: Why FlexFlame Is Different
Most outdoor cooking appliances force you to choose a specialization. A traditional gas grill is excellent for grilling. A pellet grill emphasizes wood-fired cooking and smoking. A dedicated griddle provides a large flat cooking surface. A pizza oven is optimized around very high heat.
The FlexFlame takes a different approach: combine several cooking environments into one machine.
Its electric-powered convection fan continuously circulates heated air through the cooking chamber. Ninja describes this technology as Cyclonic Heat IQ. The combination is intended to create faster cooking, more even browning and more consistent heat circulation than a conventional gas grill alone.
Grilling Performance: The FlexFlame's Strongest Case
If you are buying the FlexFlame primarily as a grill, the proposition becomes easier to understand.
Ninja specifies 424 square inches of primary cooking space and says the grill can accommodate up to 18 four-ounce burgers, three seven-pound chickens, four racks of ribs or 14 ten-ounce steaks.
Independent testing by Serious Eats found that the FlexFlame heated rapidly and produced nicely browned and charred food, including sausages, burgers and corn. Food & Wine likewise reported strong grilling performance and highlighted the combination of high heat, digital temperature control and convection airflow.
The important distinction is that the FlexFlame is not merely trying to produce a hot flame. It is using airflow to distribute that heat throughout the cooking chamber.
What That Means for Everyday Cooking
- Burgers: Plenty of surface area for family-sized batches.
- Steaks: The 600°F upper limit provides substantial high-heat capability.
- Chicken: Convection airflow can assist with browning and more even cooking.
- Ribs: The capacity is large enough for multiple racks.
- Vegetables: Air circulation makes the system useful beyond conventional grilling.
Smoking: The Feature You Should Examine Closely
This is where prospective buyers need to separate "can add smoke flavor" from "is a dedicated smoker."
The FlexFlame uses a dedicated pellet compartment to add Ninja Woodfire smoke flavor while propane remains the primary heat source. Ninja describes the system as introducing smoke through its airflow system rather than using pellets as the grill's main fuel.
Food & Wine found the smoke effect noticeable but relatively subtle. Serious Eats also reported issues with pellets catching fire during its testing, producing an acrid flavor rather than the controlled low-and-slow smoking experience expected from a dedicated smoker.
Roasting & Convection Cooking
This may actually be one of the FlexFlame's more interesting capabilities.
Because the fan continuously circulates heated air, the appliance behaves partly like a powerful outdoor convection oven. Food & Wine reported strong results from roasting chicken, duck breast, pork tenderloin, vegetables and cornbread, with some foods reportedly cooking significantly faster than in a conventional oven.
That makes the FlexFlame more useful for outdoor entertaining than a conventional grill alone.
Griddle Cooking
The FlexFlame can also be configured for griddle cooking, allowing you to prepare foods such as smash burgers, breakfast foods and other dishes that do not naturally belong on open grill grates.
However, buyers should pay close attention to the exact Amazon configuration. Ninja lists certain half and full griddle accessories separately, meaning the basic PG301BK configuration should not automatically be assumed to include every optional cooking accessory.
Pizza: A Surprisingly Serious Capability
With the appropriate pizza accessory, the FlexFlame can operate within the 450°F–600°F range used for pizza cooking. Food & Wine specifically tested the system with a 16-inch pizza stone and reported strong results, including crisp crust and effective browning.
This is another example of where the FlexFlame's convection system becomes useful: the pizza benefits not only from heat underneath but also from circulating hot air around the cooking chamber.
FlexFlame vs. Two Major Alternatives
The important question isn't simply whether the FlexFlame is good. It's what kind of outdoor cooking system you actually need.
| Feature | Ninja FlexFlame PG301BK | Weber Genesis E-325 | Traeger Woodridge Pro |
|---|---|---|---|
| Primary concept | Multi-function propane/electric outdoor cooking | Traditional premium gas grilling | Wood-pellet grilling and smoking |
| Cooking methods | Grill, smoke, roast, griddle, pizza | Grill, roast, bake, low & slow; accessories vary | Grill, smoke, bake, roast, braise, BBQ |
| Fuel | Propane + electricity + smoke pellets | Propane or natural gas depending on model | Wood pellets + electricity |
| Temperature / maximum | 200°F–600°F | Gas-grill system with dedicated sear capability | Up to 500°F |
| Cooking area | 424 sq. in. main / 544 sq. in. total | 513 sq. in. primary / 641 sq. in. total | 970 sq. in. |
| Smoke emphasis | Smoke infusion | Not the primary purpose | Dedicated wood-fired smoking system |
| Smart control | Digital onboard controls | Varies by configuration | WiFIRE app connectivity |
| Best fit | Versatility | Conventional gas grilling | Wood-fired cooking & smoking |
Specifications and configurations can vary by market, model and package. Verify the exact Amazon listing before purchasing.
What Independent Testing Reveals
This is where the FlexFlame review becomes more useful than a manufacturer feature list.
Serious Eats
Testing over an extended period found that the FlexFlame grilled effectively and heated rapidly, while also identifying drawbacks involving the convection fan, ignition experience and smoking performance.
Food & Wine
Testing reported strong results across grilling, roasting, griddling and pizza cooking, while describing the smoke flavor as relatively subtle and noting the requirement for electrical power.
The pattern is useful: the FlexFlame appears strongest as a versatile grill and outdoor convection cooker with additional cooking modes rather than as a dedicated smoker.
How We Evaluated the FlexFlame
We evaluate products for The Superstacks using a buyer-risk framework rather than simply repeating manufacturer marketing claims.
- Versatility: How many genuinely useful cooking functions does the appliance provide?
- Temperature control: Does the control system offer meaningful precision?
- Capacity: Is the cooking area appropriate for families and entertaining?
- Performance evidence: What do independent testers report after actual cooking?
- Convenience: How much setup, power and accessory management is involved?
- Long-term ownership: Warranty, replacement parts, accessories and maintenance matter.
- Hidden costs: Propane, pellets, extension equipment, griddles, pizza accessories and covers can change the real purchase cost.
- Buyer fit: Does the product solve the buyer's actual outdoor cooking problem?
Hidden Costs Buyers Should Know About
The advertised grill price is not necessarily the final cost of ownership.
- 20-lb propane tank: Not included.
- Outdoor extension cord: Required for electrical operation and not included.
- Pizza stone: Listed as an accessory.
- Griddle: Half and full griddle accessories may be sold separately.
- Cover: Worth considering if the grill will remain outdoors.
- Wood pellets: Required when using the smoke function.
- Assembly: The unit is large and heavy enough that two-person assembly is sensible.
Is the FlexFlame Good Value?
Value here should not be measured simply by dividing the purchase price by square inches of cooking area.
Suppose a household spends approximately $1,000 on the grill and uses it twice per week for five years. That would represent approximately:
This is only an illustrative calculation. It excludes propane, pellets, electricity, accessories, maintenance and the time value of money. But it demonstrates why a premium multifunctional appliance can make more practical sense for a frequent outdoor cook than for someone who grills only a few times each summer.
Pros & Cons
What We Like
- Five cooking modes in one outdoor system.
- Wide 200°F–600°F temperature range.
- Strong grilling performance reported by independent testers.
- Convection airflow can assist with roasting and browning.
- Large enough for family meals and entertaining.
- Pizza capability with the appropriate accessory.
- 10-year limited warranty from Ninja, subject to applicable terms.
- More versatile than a conventional gas grill.
What Could Be Better
- Electricity is required in addition to propane.
- The convection fan can be noticeably loud.
- Smoking performance is less compelling than a dedicated smoker experience.
- Some desirable accessories cost extra.
- Large footprint and approximately 130-lb weight reduce portability.
- Premium purchase price makes it excessive for basic grilling.
- Assembly requires substantial time and space.
Who Should Buy the Ninja FlexFlame?
Buy it if versatility is the priority.
The FlexFlame makes the most sense for someone who wants one substantial outdoor cooking station capable of handling burgers on Friday, roast chicken on Saturday, pizza on Sunday and occasional smoked foods without purchasing four different appliances.
It is particularly interesting for outdoor entertainers who value the ability to change cooking styles rather than simply maximizing smoking performance.
Who Should Not Buy It?
Skip it if simplicity is your priority.
If all you want is a propane grill that lights, heats and cooks without an electrical connection, a conventional gas grill is inherently simpler.
Likewise, if your main objective is serious low-and-slow barbecue with deep wood-fired smoke, a dedicated pellet smoker may be a better match for that specific cooking goal.
FlexFlame vs. a Traditional Weber Gas Grill
The Weber Genesis E-325 illustrates the fundamental trade-off.
The Genesis E-325 provides a substantial primary cooking area and dedicated high-heat searing capability. Its conventional gas-grill architecture also avoids the same always-on electrical dependence associated with the FlexFlame's convection system.
So the decision is less about which machine has more features and more about whether you actually want those additional cooking modes.

Is the Ninja FlexFlame a good smoker?
It can add smoke flavor, but buyers should understand the distinction between smoke infusion and a dedicated smoker. Independent testing has found the grill and roasting functions stronger than its smoking performance.
Does the FlexFlame come with a pizza stone?
Do not assume that it does. Ninja lists the 16-inch pizza stone as an accessory, so verify the exact Amazon package before ordering.
Does the FlexFlame need electricity to work?
Yes. Electricity powers the FlexFlame's electronic technology and convection system. This is one of the biggest differences between it and a basic propane grill.
Is the Ninja FlexFlame good for large families?
Its 424 sq. in. main cooking surface and 544 sq. in. total cooking area make it suitable for family meals and entertaining, although larger dedicated grills can provide substantially more total cooking space.
Does Ninja offer a warranty?
Ninja lists a 10-year limited warranty for the FlexFlame PG301 series. Always confirm the warranty terms applicable to your exact purchase region and configuration.
How heavy is the Ninja FlexFlame?
Ninja lists the PG301BK at approximately 130 lb. Because of its size and weight, plan the installation location before delivery and consider having another person available during assembly and positioning.
Final Verdict: Is the Ninja FlexFlame PG301BK Worth Considering?
The Ninja FlexFlame PG301BK is an ambitious outdoor cooking system that makes the most sense when you genuinely want multiple cooking methods in one machine.
Its strongest proposition is not that it replaces the world's best dedicated grill, smoker, griddle and pizza oven individually. Its proposition is that it brings several of those experiences together in one substantial outdoor appliance, with digital temperature control and convection airflow adding something a conventional propane grill does not.
The trade-off is equally clear: you pay for that versatility. You also accept electrical dependence, a relatively loud fan and a smoking system that independent testing suggests is less impressive than the FlexFlame's grilling and roasting capabilities.
