The best Ninja indoor grill replacement parts are the ones that match your exact model and original part dimensions. For AG-series grates, compare the Swess options; for FG551, consider the Croask or KEESHA grate, while the MOASKER plate is for GR101 and GR100 series grills.

A Ninja model name alone does not identify every compatible part. Start with the label on your grill, then compare the shape, size, and clearance of the replacement with the part you are replacing.

How we chose Ninja indoor grill replacement parts

The most useful replacement part is the one with a clear match for your grill model, dimensions, and part type. We compared the model lists and stated features for these six options, then scored how directly each fits a common replacement need.

Our score weighs specs, features and buyer feedback against what you're shopping for. A broad compatibility list can help, but it does not replace checking your exact model number and lid clearance.

The best Ninja indoor grill replacement parts by model

Match the model first, then choose between a grate, flat plate, or splatter shield. These parts do different jobs, so a strong fit for one grill or need may not suit another.

GWY Stainless Steel Splatter Shield for Ninja: Best for AG-series splatter control

The GWY shield is the pick here for owners of the named AG-series models who need a mesh screen. It measures 8.5 x 8.5 inches and lists AG300, AG300C, AG301, AG301C, AG302, and AG400 compatibility.

GWY Stainless Steel Splatter Shield for Ninja: Best for AG-series splatter control

9.6/10Our score

• 8.5 x 8.5 in mesh screen
• Compatible with AG300, AG300C, AG301, AG301C, AG302 and AG400
• Stainless steel frame and screen
• Dishwasher safe

This mesh shield is made for several AG-series models and is sized at 8.5 x 8.5 inches. It is the pick to consider when you need a splatter shield rather than a cooking grate.

See it on Amazon

Pros

• Covers multiple AG-series models
• Stainless steel mesh
• Dishwasher safe

Cons

• Does not replace a grill grate
• Model and interior fit still need checking

The fine mesh is designed to catch splashes and help keep grease and food particles away from the heating element. The brand also says this can help keep the element clean and prevent smoke from the device.

This is not a replacement cooking grate, so it won't solve a damaged food surface. Measure your grill and confirm the exact model before ordering, especially if your model suffix differs from the listed versions.

Choose it when you need the shield itself and have a listed AG-series model. If smoke control is your main concern, read what smokeless means on an indoor grill to understand how grill design and cooking conditions affect smoke.

Croask Replacement Grill Grate for Ninja Foodi: Best for FG551 replacement

Croask is the clearest fit in this group for a Ninja Foodi FG551 owner replacing a grate. Its stated size is 13.36 x 9.1 x 2.63 inches, and the product is specified for FG551.

2

Croask Replacement Grill Grate for Ninja Foodi: Best for FG551 replacement

9.5/10Our score

• Made for Ninja Foodi FG551
• 13.36 x 9.1 x 2.63 in
• Ceramic-coated nonstick surface
• Double handles

The stated FG551 fit and dimensions make this the clearest match for a buyer replacing that model's grate. Its ceramic-coated surface is described as nonstick and dishwasher safe.

See it on Amazon

Pros

• Names FG551 compatibility
• Dimensions are specified
• Double handles

Cons

• Compatibility is stated for FG551 only
• Not identified for AG-series grills

The grate has a ceramic-coated nonstick surface and double handles. Those handles give you places to grip when removing the grate, but compare the listed dimensions with your original before you buy.

Its stated compatibility is narrower than the Swess AG-series options below. If your model is FG550 or DG551, the KEESHA alternative names those models, so compare that choice too.

Swess Grill Grate Replacement Parts Compatible: Best for a broad model list

Swess names a wide set of AG, IG, LG, EG, and AG21-series model numbers for this replacement grate. Its approximate dimensions are 10.1 x 10 x 3 inches, with raised handles around 3 inches high.

3

Swess Grill Grate Replacement Parts Compatible: Best for a broad model list

9.4/10Our score

• Lists AG, IG, LG and other model numbers
• About 10.1 x 10 x 3 in
• Ceramic-coated surface
• Dishwasher safe

This grate has the broadest compatibility list among these picks, including selected AG, IG and LG models. Compare your exact model number and lid clearance before choosing it.

See it on Amazon

Pros

• Extensive model list
• Ceramic-coated surface
• Lid clearance advice is included

Cons

• The long compatibility list needs careful matching
• Raised handles may affect lid clearance

The wide list is useful only if your exact model appears in it. Swess also advises measuring interior height and lid clearance, since raised handles may stop the grill from closing if there is not enough room.

The grate has a ceramic-coated surface and is described as dishwasher safe. Check your model suffix carefully because Ninja model numbers can look similar while belonging to different grill configurations.

Swess Grill Grate for Ninja Foodi AG301: Best for an AG301 grate set

This Swess option is aimed at several AG-series grills and includes a cleaning brush and 100 sheets of air fryer parchment paper. Its grate measures 10.1 x 10 inches and is made from ceramic-coated aluminum.

4

Swess Grill Grate for Ninja Foodi AG301: Best for an AG301 grate set

9.2/10Our score

• Fits listed AG, IG and LG models
• 10.1 x 10 in grate
• Includes parchment paper and cleaning brush
• Ceramic-coated aluminum

This option pairs an AG-series replacement grate with parchment paper and a cleaning brush. Check your model against its listed fit before ordering.

See it on Amazon

Pros

• Includes a brush and parchment paper
• Lists several AG-series models
• Ceramic-coated aluminum

Cons

• Accessory bundle may be unnecessary if you only need a grate
• Dimensions differ from the FG551 grate

The accessory bundle may be useful if you also want a brush and parchment paper, but the fit is the key point. The stated models include AG300, AG300C, AG301, AG301C, AG302, and AG400, along with selected IG and LG models.

If you already have the extras, a replacement grate without the bundle may suit you better. For add-ons that expand what a Ninja Foodi grill can do, see best Ninja Foodi grill accessories.

MOASKER GR101 Grill Plate Replacement Part: Best for Ninja Sizzle GR101

MOASKER is a flat plate replacement for Ninja Sizzle GR101 and GR100 series grills. The stated plate size is 14 x 10.8 inches, which makes it a different part from the raised AG and FG551 grates above.

5

MOASKER GR101 Grill Plate Replacement Part: Best for Ninja Sizzle GR101

8.9/10Our score

• Made for Ninja GR101 and GR100 series
• 14 x 10.8 in plate
• Steel construction
• Nonstick surface

This flat plate is intended for the Ninja Sizzle GR101 and GR100 series, rather than the AG or FG551 grills. Match the model and plate dimensions before choosing it.

See it on Amazon

Pros

• Names the GR101 and GR100 series
• Dimensions are stated
• Flat plate format

Cons

• Not a raised grill grate
• Fit should be confirmed against the original plate

The plate is described as steel with a nonstick surface. Check your original plate's shape and dimensions, since this option is not identified for the AG-series or Foodi Smart XL models.

Choose it when you need a flat griddle-style surface for a compatible GR-series grill. If you are comparing countertop cooking surfaces more broadly, our guide to how indoor electric grills work explains how the heating surface and removable parts fit into the appliance.

KEESHA FG551 FG550 DG551 Grill Parts Grill: Best for FG550 or DG551 fit

KEESHA names FG550, FG551, and DG551 Smart XL grills, with dimensions of 13.36 x 9.1 x 2.63 inches. That model list makes it worth comparing with the FG551-only Croask option when your label says FG550 or DG551.

6

KEESHA FG551 FG550 DG551 Grill Parts Grill: Best for FG550 or DG551 fit

8.7/10Our score

• Names FG550, FG551 and DG551
• 13.36 x 9.1 x 2.63 in
• Dual handles
• Care instructions call for hand cleaning and oiling

This grate names three Foodi Smart XL models and shares dimensions with the Croask FG551 option. Its care instructions call for hand cleaning, drying and a light coat of oil.

See it on Amazon

Pros

• Includes FG550 and DG551 compatibility
• Dimensions are stated
• Dual handles

Cons

• Care routine differs from dishwasher-safe options
• Seasoning is recommended before first use

The product description identifies a heavy-duty cast iron grate with a ceramic coating and dual handles. Its care directions call for seasoning before first use, then brushing, drying, and applying a thin layer of vegetable oil; they also say not to use a dishwasher.

That care routine differs from dishwasher-safe options, so factor cleanup into your choice. Match the exact model and original size before ordering, even when the dimensions appear close to another replacement.

What should you check before ordering a Ninja grill part?

Check the grill's full model number, the part's dimensions, and whether the replacement has handles or raised edges. Those checks help prevent a grate from being too large, too small, or too tall for the lid to close.

Model labels may include letters after the main number, so compare the whole code rather than just “AG301” or “FG551.” If a model is missing from the compatibility list, confirm fit before buying.

For grates with raised handles, measure the available height inside the grill and compare it with the replacement. The Swess grate with a broad compatibility list specifically notes lid clearance, while the FG551 parts share a larger stated size than the AG-series grates.

Also confirm the part type. A flat GR101 plate, a raised grill grate, and a mesh splatter shield are not interchangeable even if all are sold as indoor grill parts.

Which Ninja replacement grate is right for your model?

Choose by model family and part style: the AG-series options are around 10 inches across, while the FG551 replacements are larger at 13.36 x 9.1 inches. The GR101 option is a flat plate, and the GWY accessory is a splatter shield.

For an AG301 or a listed related model, compare the two Swess grates by included extras and model coverage. For FG551, compare Croask with KEESHA, especially if your grill is FG550 or DG551.

If you also own another countertop appliance, see best Presto electric griddle replacement parts for a separate appliance-specific guide. For this Ninja roundup, the safe decision rule is simple: match the complete model number, then confirm dimensions and clearance before ordering.

Frequently asked questions

How do I find the right Ninja indoor grill replacement part?

Find the model number on your grill and match it to the part's compatibility list. Then compare the replacement's dimensions with your original part and check that handles or raised edges leave enough room for the lid to close.

A similar-looking Ninja part can still fit a different grill.

Are Ninja Foodi AG301 and FG551 grates interchangeable?

Don't assume they are interchangeable. The AG301 grate options here measure about 10.1 x 10 inches, while the FG551 grate is listed at 13.36 x 9.1 x 2.63 inches.

Use the exact model number and dimensions to choose a replacement.

Does a splatter shield replace the grill grate?

No. A splatter shield is a mesh screen, while a grill grate is the cooking surface that holds food.

The GWY shield is listed for several AG-series models and measures 8.5 x 8.5 inches.

Choose the part that matches what is missing or worn.

Can I put a replacement Ninja grill grate in the dishwasher?

Some options here are described as dishwasher safe, including the Croask and Swess grates. The KEESHA instructions instead call for hand cleaning, drying and oiling after use.

Follow the care directions for the specific part you choose.

What if my Ninja model is not listed?

Treat an unlisted model as unconfirmed. Compare the original part's dimensions and shape, then contact the part maker or seller to confirm fit before ordering.

This matters especially when a grate has raised handles, since they can affect whether the grill lid closes.
