Ninja Foodi Smart XL Grill Review — Indoor Grill + Air Fryer

Intro

The Ninja Foodi Smart XL Grill (model FG551) markets itself as an all-in-one indoor grill and air fryer that sears, roasts, bakes, broils, dehydrates and air-crisps. On paper it’s a heavy-duty countertop appliance: stainless-steel body, 1,760 watts (110 V), a 500°F max temperature and an included Foodi Smart Thermometer that the listing says continuously monitors food and automatically shuts the unit off when your target temperature is reached. Owners report it delivers fast, well-seared results for steaks, burgers and air-fried sides, but buyer experiences also surface a few real-world caveats you’ll want to weigh before gifting.

What it is / first look

The FG551 is the Ninja Foodi Smart XL: an indoor electric grill and air fryer combo described in the listing as a 6-in-1 appliance. Key listed specs are stainless-steel construction, 1,760 watts of output, a maximum temperature setting of 500°F, and a compact footprint of roughly 15.75" deep x 16.54" wide x 11.1" high. The unit weighs about 22.4 pounds and is sold in a Black & Silver finish.

The thing ships with a handful of practical parts: a 9" x 12" high-density grill grate (nonstick, listed as PTFE/PTFOA-Free, ceramic coating), a 4-quart cooking pot with a nonstick ceramic coating (listed PTFE/PFOA-free), a 4-quart crisper basket (same nonstick claim), a cleaning brush, recipe guide and the Foodi Smart Thermometer. The listing also calls out dishwasher-safe parts and a 1-year limited warranty.

Functionally the listing emphasizes a few headline features: Ninja’s cyclonic air flow for “surround searing” and char marks at up to 500°F, a Smart Cook System with four protein presets and nine doneness levels, and a smoke-control system made of a splatter shield, a cool-air zone and a temperature-controlled grill grate. Ninja claims the 4-qt crisper basket can air-fry with up to 75% less fat than deep frying (tested against hand-cut, deep-fried French fries), and that the XL grate fits up to six steaks or 24 hot dogs—enough to serve a family in one batch.

Who this is a good gift for

This is a practical countertop upgrade — not a novelty — so the match matters. Below are the recipient types who get the most value from this model and the assumptions that must be true for it to be a good fit.

1) Apartment dwellers who want grill flavor without outdoor space

Why it fits: The listing positions the grill as an indoor, virtually smoke-free option with a smoke-control system and a splatter shield, and owners praise its ability to produce charred sear marks and juicy steaks without an outdoor setup. Assumption: the recipient will follow the manufacturer’s instructions (owners note oil quantity and cleaning the smoke screen are important for minimizing smoke).

2) Busy families who want bigger batch cooking

Why it fits: The XL grate is listed to fit up to six steaks or 24 hot dogs and the 4-quart basket lets you air-fry up to 2 lbs of fries at once. If you’re buying for a household that wants fewer oven cycles and quicker dinners, the extra capacity and multi-function modes (grill, air fry, roast, bake, broil, dehydrate) make this a practical main-gift. Assumption: the recipient has counter space (dimensions and the unit’s 22.4 lb weight are non-trivial).

3) A novice cook who struggles with meat doneness

Why it fits: The Smart Cook System plus the Foodi Smart Thermometer is designed to remove guesswork by letting you pick protein and doneness level; the listing says the thermometer monitors and automatically shuts the grill off when the target temp is reached. Owners frequently report reliably juicy steaks and properly cooked chicken when they use the thermometer and presets. Assumption: the recipient will accept preset-driven cooking and trust the auto-shutoff instead of manual monitoring.

4) The one who wants to replace multiple devices

Why it fits: If a person is short on storage and already owns an air fryer and a separate electric grill or toaster oven, this unit’s 6-in-1 claims and included accessories make it a good consolidation gift. Assumption: the recipient will use multiple modes (not just one) and is comfortable with the slightly larger footprint on the counter.

5) A tailgating organiser (indoors or in covered spaces)

Why it fits: The listing explicitly suggests it “now you can tailgate indoors,” meaning it’s intended for quick high-heat grilling in places where an outdoor grill isn’t feasible. Assumption: organizers will keep the appliance under an exhaust hood or well-ventilated area and will clean the smoke screen regularly.

In daily use

Owners’ repeated praise centers on speed, sear quality and convenience. The 500°F cyclonic air flow and the high-density grill grate are listed as the mechanics that create strong sear marks and quick cooks: owners report steaks done in ~10 minutes, bone-in chicken in around 20 minutes, and much faster bake/air-fry cycles compared with a conventional oven. Users describe it as intuitive thanks to the touch controls and Smart Cook presets.

Cooking performance and timing

The listing’s Smart Cook System and thermometer presets simplify steak and poultry: pick protein, choose doneness and the grill “does the rest,” according to the listing. Owner feedback supports this in practice — many reviews say the presets plus thermometer deliver juicy, evenly cooked meats without a lot of fiddling. Several owners do note a consistent pattern: the Foodi cooks faster than a conventional oven or package directions imply, so times usually need to be reduced and temps treated conservatively (one owner specifically says lower temp + shorter time than package instructions).

Crispiness, air frying and health claims

The 4-qt crisper basket is listed for air-frying with up to 75% less fat vs deep frying (listing tests referenced). Owners report satisfying crisp results on fries, potato wedges and frozen items when they use recommended temps and avoid heavy oiling. The listing warns not to assume the outcome of deep frying will be identical—this is an air-crisp method that reduces oil usage.

Cleaning and maintenance

The listing states parts are dishwasher safe (the basket, cooking pot and grill grate are described as nonstick and dishwasher-safe). Owners consistently point out the necessity of cleaning the top circular smoke screen after use for a low-smoke experience; one owner called that screen “hard enough to clean” after a single use and noted replacement screens are sold separately. The included cleaning brush is called out by owners as much easier to use on the grate than a sponge. Expect routine rinsing/soaking or loading the removable pieces into the dishwasher; the outer unit will still need wiping.

Noise and preheat behavior

Several owners mention the preheat fan’s “siren whine” during warm-up, which settles after the unit starts. It’s loud enough that one owner checked for an external noise source. Plan for some fan noise and hot air exhaust during preheat and operation.

Materials & build quality

The listing describes the FG551 body as stainless steel. The removable cooking pot, crisper basket and grill grate are described as having a nonstick ceramic coating (listing language: PTFE/PFOA-free, ceramic coating). Dimensions and weight are given — 15.75" D x 16.54" W x 11.1" H and about 22.4 pounds — which makes this a sturdy, counter-capable unit rather than a featherweight travel appliance.

Owners generally praise the build and finish: common positive themes are that the machine looks solid, preheats quickly and is “well made” with nothing easy to chip. A few owners compared its durability favorably to prior Ninja grills, saying older models lasted a long time. The included stainless appearance and heavy weight contribute to a perception of quality.

That said, there are a few durability caveats in owner notes: one buyer reported an electrical failure described as a fuse blow on first trial (a single severe complaint among many positives), and several owners caution that greasy meats produce more smoke and therefore require more frequent cleaning of the smoke-control components. If you expect heavy, sloppy frying, the plating and vent elements may need regular maintenance to preserve performance.

Safety considerations

The listing states the unit has an Automatic Shut-Off and that the Foodi Smart Thermometer continuously monitors food temperature and will automatically shut the grill off when the target temperature is reached — two useful safety features for distracted cooks. The maximum listed temperature is 500°F, so the grill reaches high heat quickly and should be treated like any high-temperature appliance.

Owner feedback highlights three practical safety items to pass along with the gift:

• Thermometer reliability — mixed reports: while the listing centers the Smart Thermometer as a convenience and safety feature, owner comments on the thermometer are mixed. Several reviewers praise it for consistently producing well-cooked meat and an automatic shut-off; one group of comments warns that some buyers experienced thermometer problems. Frame the thermometer as a strong feature that some owners advise pairing with common sense (and an accurate kitchen thermometer if you’re concerned).
• Smoke and grease management: the listing calls out a smoke-control system (splatter shield, cool-air zone, temperature-controlled grate). Owners repeatedly report that greasy meats or excessive oil lead to increased smoke; the recommended approach in owner notes is to use minimal oil for a smokeless cook and to clean the top circular smoke screen after each use to maintain the low-smoke promise.
• Electrical/operation events: while most owner reports describe normal operation, at least one owner reported a severe electrical failure (a fuse or electrical blast) on first use. That’s an outlier in the available owner notes, but it’s significant enough that you should confirm the unit’s condition on arrival and register the appliance with the manufacturer per the 1-year limited warranty instructions if anything looks amiss.

Additional practical safety advice: treat surfaces as hot, keep children and pets away during operation, and use proper ventilation. The listing’s dishwasher-safe claim applies to removable parts; the main body should be wiped down according to manufacturer instructions.

Who should skip it

• If the gift recipient has very limited counter space or prefers a minimal kitchen footprint, this unit’s 16.5" width and 22.4 lb weight make it a medium-space appliance rather than something tucked away frequently.
• If the recipient needs an absolutely silent appliance: owners note a pronounced fan noise during preheat (a siren-like whine that settles), which can be annoying in noise-sensitive households.
• If the recipient plans to cook very greasy items regularly without routine cleaning—multiple owners warn that heavy grease leads to smoke and requires more maintenance to keep the smoke-control system effective.
• If the recipient wants a pure deep-fryer or is expecting identical results to traditional deep frying: the listing claims up to 75% less fat versus deep frying for fries in the crisper basket, but it’s still an air-crisp method and won’t replicate submerged oil frying exactly.

Verdict

Bottom line: the Ninja Foodi Smart XL Grill (FG551) is a practical, well-specified countertop appliance that actually replaces a couple of devices for many households. The listing-backed combination of 1,760 watts, 500°F cyclonic air, Smart Cook presets and a built-in thermometer makes it a compelling gift for someone who wants real sear marks and faster weeknight cooks without outdoor grilling. Owners consistently praise its cooking speed, sear quality and multi-function versatility, and the included accessories (4-qt crisper and cooking pot, 9" x 12" grill grate, thermometer and cleaning brush) are thoughtful for everyday use.

Gifting risk is moderate: expect a learning curve (reduce times from package directions), plan for routine cleaning of the smoke screen for low-smoke performance, and accept the unit’s footprint and fan noise during preheat. There are a small number of serious-sounding electrical complaints in the owner notes, so inspect on delivery and use the one-year limited warranty path if anything is wrong.

Check before you buy — quick checklist for gift shoppers

• Confirm recipient has ~16.5" of counter width and a place to store a ~22.4 lb unit.
• Make sure the recipient is comfortable with an electric appliance that reaches up to 500°F and uses a fan (some preheat noise).
• Verify whether the recipient prefers hands-off, preset cooking; the Smart Cook System and thermometer are designed for that workflow.
• Plan to include a short note about cleaning the top circular smoke screen and using minimal oil for smokeless results—owners repeatedly point this out.
• Keep the 1-year limited warranty info and registration details handy in case of issues on arrival.

Verdict rating (practical guidance): buy if the recipient has the counter space and wants a multi-function grill/air fryer that sears well and cooks quickly; maybe skip if counter space, noise sensitivity, or heavy-grease cooking and minimal maintenance are concerns.
