Cuisinart CMD-108 Melting Dome
At a glance
  • Traps heat under the dome to quickly melt cheese, steam vegetables, and cook food evenly.
  • Retains moisture to intensify flavors by circulating heat and steam over food.
Why we picked it

The Cuisinart 9-inch dome is a go-to choice when you need to cover two or three smash burger patties at once on a flat top grill. Its wide diameter creates an effective heat trap that melts cheese evenly and locks in moisture, preventing patties from drying out during the crucial final seconds of cooking. This concentrated heat is also effective for steaming vegetables or gently warming buns next to the main cook.

Built from heavy-duty stainless steel, the dome is designed to handle repeated high-heat sessions on a Blackstone, Camp Chef, or other outdoor griddle without warping. The rolled edge adds structural integrity, while the integrated handle provides a secure grip for lifting and placement. Its durable construction and versatile size make it a reliable tool for anyone serious about upgrading their flat top grilling results.

Outset Burger Cheese Melting Dome

4.6BBQ Report Score
Outset Burger Cheese Melting Dome
At a glance
  • Creates a mini oven effect to speed up cook times and melt cheese faster.
  • Silicone-wrapped handle provides a safer, secure grip when the dome is hot.
  • 7.5-inch width covers standard and oversized smash burger patties comfortably.
Why we picked it

At 7.5 inches, the Outset dome sits between compact 6-inch and wider 9-inch options, making it a versatile size for a standard or slightly oversized smash burger patty. The key feature is its silicone-wrapped handle, which provides a comfortable, heat-resistant grip that lets you lift and reposition the dome confidently, even when your flat top is running at maximum temperature. This added safety is a significant advantage over all-metal handles that can get dangerously hot.

By creating a mini-oven effect, the dome traps steam and accelerates cook times, ensuring cheese is perfectly melted in seconds. Its sturdy stainless steel construction is compatible with any high-heat cooking surface, including outdoor griddles, stovetop cast iron pans, and traditional grill grates, making it a flexible tool for various cooking methods.

HULISEN Cheese Melting Dome & Smashed Burger Press
At a glance
  • Includes both a 9-inch basting cover and a 6.2-inch flat burger press for the full smash method.
  • The flat press creates a caramelized crust that seals in juices and delivers the classic smash texture.
  • Dome features a heat-resistant silicone handle for safer handling at high griddle temperatures.
Why we picked it

This HULISEN kit provides the two essential tools that define the classic smash burger method: a 6.2-inch flat press for creating a perfect crust and a 9-inch basting cover for the final cheese melt. Using both in sequence is the most efficient way to achieve professionally seared edges and a gooey, perfectly melted top. The press is wide enough to handle standard patties, while the dome can cover two or three burgers at once.

The press's flat, smooth surface ensures uniform thickness and maximum contact with the griddle, which is critical for developing the Maillard reaction's savory crust. Both tools are made from brushed stainless steel that holds up to the repeated pressure and high heat of flat top cooking, and the dome's heat-resistant handle adds a layer of safety during use.

  • Compact 6-inch diameter targets individual smash burger patties for precise, fast cheese melting.
  • 360-degree rolling edge provides a solid structure that resists deformation over time.
  • Helps food retain its original flavor and moisture with a tight heat seal.
Why we picked it

Choosing the right grill topping dome is a simple upgrade for any smash burger enthusiast. Individual patty precision favors a 6-inch dome, while high-volume cooking calls for a 12-inch or rectangular option. The key is trapping heat effectively for a perfect cheese melt and juicy patty. A quality stainless steel dome with a heat-resistant handle makes smash burger results more consistent every time you fire up the griddle.

What toppings do you put on smash burgers?

Classic smash burger toppings lean toward simple, high-contrast flavors that complement the seared, caramelized patty. American cheese is the most popular choice because it melts smoothly under a dome, followed by shredded iceberg lettuce, sliced onion, pickles, and a smear of burger sauce or mayo. Some cooks add crispy bacon, grilled onions, or jalapeños for extra flavor. The key is keeping the topping stack compact so the flavors stay balanced rather than overwhelming the patty.

What is the 5-6-7 rule for burgers?

The 5-6-7 rule is a temperature guide for grilled burgers rather than smash burgers, but it is worth knowing as a general reference. It refers to internal temperatures: 5 minutes per side for medium-rare (140°F), 6 minutes per side for medium (155°F), and 7 minutes per side for well done (165°F). Smash burgers cook much faster because of their thin profile and direct contact with a hot flat top. Most smash patties cook through in 2-3 minutes total, with the cheese melt taking only an additional 20-30 seconds under a dome.

What to put on the griddle before cooking smash burgers?

A light coat of high-smoke-point oil — such as avocado oil, canola oil, or refined coconut oil — applied to a preheated griddle surface is all you need before cooking smash burgers. The goal is a thin, even film rather than a heavy pool. Too much oil will prevent the patty from developing a proper crust on contact with the hot metal surface.

How to get the best crust on a smash burger?

A screaming hot flat top at 400-450°F is the foundation. Place a loosely formed ball of ground beef onto the hot surface, then press it flat immediately with a burger press or heavy spatula. Use an 80/20 fat ratio and hold the press firmly for 10-15 seconds to maximize contact between the meat and the hot griddle. Do not move the patty after smashing it. Let the Maillard reaction do its work — you will see the edges turn brown and crispy before you need to flip. Once flipped, add cheese and place a melting dome over the patty to complete the cook.

What is the secret to a good smash burger?

The most important secret is to smash the patty quickly on a very hot surface. The faster and harder you press, the more surface area contacts the griddle, and the more of that savory crust you get. Using ground beef with an 80/20 lean-to-fat ratio ensures enough fat to baste the patty as it cooks. The second secret is the melting dome. Placing a grill topping dome over the patty immediately after flipping and adding cheese traps heat and steam, delivering a perfectly melted, restaurant-quality finish in seconds. Using the right dome size for your patty — 6 inches for single patties, 9 to 12 inches for doubles — keeps the process efficient and repeatable.
