Best Stainless Steel Griddles

The Onlyfire 12.5-by-16-inch griddle is the best stainless steel grill-top insert for most outdoor cooks because it fits more grills than a large plate, provides over 200 square inches of cooking area, and includes raised walls and a grease trough. Choose the wider Stanbroil when your grill has room, or the Bull Pro 97020 when you own a compatible Bull grill and want a heavy slide-in plate.

These are outdoor griddle inserts, not indoor stovetop pans or complete flat-top grills. Search results for an indoor “stainless steel griddle” often describe a stainless housing around a coated or cast-iron cooking surface. Every pick below has a stainless cooking surface, but you still need to confirm its dimensions against your grill before ordering.

Best stainless steel griddles at a glance

Pick	Best for	Listed dimensions	Fit
Onlyfire universal	Most outdoor cooks	16 by 12.5 inches	Many gas and charcoal grills
Stanbroil universal	A wider surface	18 by 12.5 inches	Grills with enough grate clearance
Bull Pro 97020	Compatible Bull grills	30 by 18 inches	Bull 30-, 38-, and 46-inch grills

Measure usable grate width and depth with the lid closed. Leave room for airflow, handles, warming racks, and any fixed burners or flavorizer bars identified in the grill manual.

1. Best overall: Onlyfire 12.5-by-16-inch universal griddle

Onlyfire is the most practical starting point because its compact footprint is easier to fit than a full-width plate. The exact Amazon record lists a 16-by-12.5-inch surface, 2.7-inch height, stainless construction, raised sidewalls, and a grease trough. The maker says it provides more than 200 square inches of cooking area.

The smaller surface leaves part of a typical grill grate open. That can be useful when you want a griddle zone for onions, eggs, or sandwiches and a grate zone beside it. It also limits batch size, so the Stanbroil is a better fit for cooks who routinely cover a wider grill.

Customer feedback in the retailer snapshot was mixed on warping, heat distribution, and cleanup. Preheat gradually, avoid creating a severe hot spot under an empty plate, and follow the grill and griddle instructions rather than treating stainless construction as a guarantee against distortion.

2. Best wider insert: Stanbroil 18-by-12.5-inch griddle

Stanbroil adds roughly two inches of width while keeping the same listed depth as the Onlyfire. Its cross-braced underside is intended to support the wider plate, and the raised sides include ventilation openings. A grease well collects runoff at the front.

The added width gives pancakes, chopped vegetables, or several sandwiches more breathing room. It also narrows the set of grills that can hold it with proper clearance. Measure the actual 18-by-12.5-inch footprint and the 2.7-inch height, including the space beneath a warming rack.

Retailer feedback was mixed on durability and cleaning, with reports of first-use warping among the negative comments. That makes gradual heating and correct burner coverage important. Do not assume the cross bracing makes the plate immune to thermal stress.

3. Best Bull grill upgrade: Bull Pro 97020

The Bull Pro 97020 is a different proposition from the universal inserts. It is a 30-by-18-inch, 20-pound slide-in plate designed for Bull’s 30-, 38-, and 46-inch grills. Bull lists 304 stainless steel and a large grease trough.

That model-specific fit is its strength. A compatible grill gets a broad, substantial flat surface instead of a small accessory sitting on the grate. It is a poor speculative purchase for another grill brand because the dimensions, supports, clearances, and grease path may not align.

The exact-ASIN snapshot showed limited stock and far fewer ratings than the universal picks. Confirm model compatibility in Bull’s current documentation before buying, and plan for safe handling and storage of a 20-pound plate.

How we chose

This roundup covers removable outdoor grill-top griddles with a stainless cooking surface. We excluded indoor products whose “stainless” description referred only to the housing, and we excluded coated and cast-iron plates because they answer a different material query.

Bright Data supplied exact-ASIN Amazon records on July 11, 2026. We used those records for current availability, dimensions, rating snapshots, review counts, feature claims, and primary image candidates. We did not conduct hands-on testing, display scraped prices, or treat retailer ratings as controlled performance tests.

Fit came first, followed by usable area, grease management, honest durability signals, and whether the product served a distinct buyer. All three primary image URLs returned JPEG image bytes during publication checks. The cards retain a visible text-and-button fallback if a third-party image later fails.

How to choose a grill-top griddle

Start with fit. Measure the clear grate area, then compare width, depth, and height with the grill lid closed. Check the grill manual for required airflow and whether a plate may sit over every burner. “Universal” means broad compatibility, not guaranteed compatibility.

Choose enough surface for the food you cook without automatically covering the whole grill. A smaller insert preserves a direct-grate zone and is easier to store. A wide insert handles larger batches but weighs more, traps more heat, and needs a broader, more even heat source.

Bare stainless steel is not naturally nonstick. Preheat moderately, add oil, and give food time to release. The same temperature cues used to keep stainless steel pans from sticking apply, but your grill manual controls burner setup and safety.

Stainless steel griddle questions

Can you use these stainless steel griddles indoors?

No. These picks are outdoor grill accessories. They are not intended to bridge indoor stovetop burners, and using an outdoor grill indoors creates a deadly carbon-monoxide hazard. For indoor cooking, choose a pan designed for your cooktop.

Will a stainless steel griddle warp?

Any broad metal plate can distort under uneven thermal stress. Customer feedback for the universal picks includes some warping reports. Correct fit, gradual preheating, appropriate burner settings, and avoiding a concentrated hot spot under an empty plate can reduce stress but cannot guarantee that warping will never occur.

Does a grill-top griddle work on induction?

Not as intended. These products are outdoor grill inserts, even if a particular stainless alloy responds to a magnet. For cookware designed around electromagnetic heating, use our induction-compatible stainless cookware guide.

For indoor searing and shallow cooking, compare the best stainless steel frying pans. If you need a complete kitchen collection instead of an outdoor insert, start with our recommended stainless steel cookware sets. The cookware buying guide explains how construction, vessel shape, and cooktop fit change the decision.
