Easy Steak Burger with Cheddar Sauce and Maple Ketchup
This steak burger layers tender slices of seared beef with warm cheddar sauce and a tangy maple ketchup inside toasted buns. The ketchup is cooked until glossy, the steak is finished gently in the oven, and the cheese sauce stays smooth because it never boils. The main mistake to avoid is relying on time alone for the beef; a thermometer gives a much more dependable result.
This is closer to a steak sandwich than a conventional hamburger. Instead of shaping ground beef into patties, a thick whole steak is seared, roasted, rested and sliced across the grain. It is a rich, protein-forward burger that works for a weekend lunch, a casual supper or any time you want something more substantial than a standard cheeseburger.
This recipe is based on my YouTube video, with a few adjustments since publication. I reduced the garlic in the ketchup, added clearer liquid measurements, stabilized the cheddar sauce and replaced the fixed steak cooking time with a temperature-based method. The spirit of the original recipe stays the same, but the result is easier to reproduce in different kitchens.

What Makes This Steak Burger Different
The first difference is the beef. A regular cheeseburger is built around a ground beef patty, while this one uses slices of whole-muscle steak. That gives the sandwich a firmer bite and a more pronounced steak flavour. It also means the meat must be sliced thinly and against the grain. Thick slices cut in the wrong direction can make even a tender steak seem chewy.
I make it this way because the steak can develop a deeply browned exterior while remaining juicy inside. Searing first gives it colour, then the lower oven temperature finishes the centre more gently. The Montreal steak seasoning goes on after the initial sear so the garlic, pepper and other spices are less likely to burn in the hot pan.
This version is also different from my classic cheeseburger with maple ketchup, which uses ground beef and melted cheese directly on the patty. It is also distinct from my mushroom steak burger with Dijon sauce, where mushrooms and mustard provide most of the character. Here, the defining elements are sliced steak, homemade ketchup and a separate pourable cheddar sauce.
The burger is undeniably rich, but the ketchup contributes enough acidity and sweetness to keep the beef and cheese from tasting flat. Toasting the buns is important too. An untoasted bun absorbs the sauces quickly and can become soggy before the burger reaches the table.
Ingredients You Need
For the steak burgers
Use one thick top sirloin, strip steak or another tender grilling steak weighing about 12 ounces. A thickness of approximately 1½ inches is ideal because it gives you enough time to brown the exterior without immediately overcooking the centre.
You will also need two burger buns, duck fat or neutral cooking oil and Montreal steak seasoning. Duck fat adds a savoury flavour, but the recipe still works with a high-heat oil.
For the maple ketchup
The ketchup starts with tomato paste rather than bottled ketchup. Tomato paste provides concentrated tomato flavour, but it must be loosened with enough water before simmering. The adjusted recipe uses apple cider vinegar, maple syrup, onion powder, garlic powder, salt and Worcestershire sauce.
The original video used a generous amount of garlic powder. I prefer to reduce it because too much can become harsh after simmering. What I look for here is a smooth, spoonable ketchup that leaves a visible trail when a spatula is drawn across the bottom of the pan.
This quantity makes more ketchup than two burgers require. Keep the remainder refrigerated for fries, sandwiches or another batch of burgers.
For the cheddar sauce
Use finely grated aged cheddar and 15% cooking cream or half-and-half. A small amount of cornstarch helps prevent the cheese from separating and gives the sauce a smoother texture.
Grate the cheese yourself when possible. Pre-shredded cheese is usually coated with anti-caking ingredients that can make a sauce grainy. The cheddar should be added gradually over low heat, and the sauce should never reach a rolling boil.
Step-by-Step Instructions
1. Cook the maple ketchup
Place the tomato paste, water, apple cider vinegar, maple syrup, onion powder, garlic powder and salt in a small saucepan. Whisk until no dry pockets of tomato paste remain.
Bring the mixture to a gentle simmer over medium heat, then immediately reduce the heat to low. Cook for 12 to 18 minutes, stirring frequently and scraping the corners of the saucepan.
At first, the mixture will look loose and slightly dull. As it cooks, it should become darker, smoother and glossier. It is ready when it resembles bottled ketchup but is still soft enough to spread. Do not reduce it until it becomes a stiff paste because it will continue to thicken as it cools.
Remove it from the heat and stir in the Worcestershire sauce. Taste once it has cooled slightly. Add a teaspoon of water if it becomes too thick.
2. Sear the steak
Preheat the oven to 300°F. Pat the steak dry with paper towel. A dry surface browns much more effectively than a damp one.
Heat a heavy oven-safe skillet over medium-high to high heat. Add the duck fat or oil. When the fat is shimmering, place the steak in the pan.
Sear the broad sides for approximately 1½ to 2 minutes per side, until a dark brown crust develops. Briefly sear the edges as well. The meat should release from the pan without much resistance once a proper crust has formed.
3. Season and finish the beef in the oven
Remove the skillet from the heat. Coat the steak lightly with Montreal steak seasoning, pressing it onto the broad sides and edges.
Transfer the skillet to the oven. Begin checking the internal temperature after approximately 8 minutes. The precise time depends on the steak’s thickness, starting temperature and the performance of the oven.
For a dependable published recipe, cook whole-muscle beef to an internal temperature of 145°F, followed by a rest. Insert the thermometer into the thickest part from the side so the tip reaches the centre.
The mistake to avoid is leaving the steak in the oven for a fixed 25 or 30 minutes without checking it. A thinner steak may be done much sooner.
4. Rest and slice the steak
Transfer the steak to a cutting board and let it rest for 8 to 10 minutes. Resting allows the temperature to settle and reduces the amount of juice lost during slicing.
Cut the steak into thin slices across the grain. Look at the direction of the muscle fibres and position the knife perpendicular to them. The slices should bend easily and remain visibly moist.
For another way to serve beef in a handheld meal, my quick bavette steak pitas use thinner meat and a faster stovetop method.
5. Make the cheddar sauce
While the steak rests, toss the finely grated cheddar with the cornstarch. Pour the cream into a small saucepan and warm it over medium-low heat until steaming. Do not let it boil.
Reduce the heat to its lowest setting. Add the cheddar a small handful at a time, stirring until each addition melts before adding more. Finish with black pepper.
The finished sauce should pour from a spoon in a thick ribbon. If it is too thick, stir in one tablespoon of warm cream or milk. If oil begins collecting around the edges, the pan is too hot. Remove it from the burner and stir gently until the sauce comes back together.
The same attention to temperature is useful in other rich beef recipes, including steak with creamy garlic cheese sauce and pan-seared steak with three-cheese sauce.
6. Toast and assemble the burgers
Split the buns and toast the cut surfaces in a dry skillet or under the broiler. They should be lightly golden and feel dry at the surface without becoming hard.
Spread maple ketchup over the bottom half of each bun. Divide the sliced steak between the buns, folding the slices rather than pressing them into a compact layer. Spoon the warm cheddar sauce over the beef and close with the top buns.
Serve immediately while the sauce is fluid and the bread is still crisp at the edges.
Chef’s Notes for a Better Result
A very lean steak can still work, but it needs careful cooking. Top sirloin is a practical choice because it has more beef flavour than tenderloin and is easier to slice into a burger.
Do not pour cold cream into melted cheese or add all the cheese at once. Either mistake can shock the sauce and create clumps. Warm cream and gradual additions give the cheese time to melt evenly.
The ketchup should taste slightly sharper on its own than you expect. Once it is combined with sweet bread, beef and cheddar, that acidity becomes less noticeable and helps balance the whole sandwich.
This is not intended to replace a classic ground beef burger. For that texture, try a cheese-filled Juicy Lucy burger or a gourmet burger with bacon and aged cheddar.
Substitutions
Top sirloin can be replaced with strip steak or ribeye. Ribeye provides more fat and a softer bite, while strip steak has a firmer texture and stronger beef flavour. Tenderloin is exceptionally tender but milder.
Duck fat can be replaced with beef tallow, avocado oil or another neutral high-heat cooking oil. Butter can be used for flavour, but it burns more quickly during the initial sear.
Aged cheddar can be replaced with medium cheddar, Monterey Jack or raclette. Very aged, crumbly cheddar may require a little more cream to become smooth.
Apple cider vinegar can be replaced with red wine vinegar or white wine vinegar. Avoid strongly flavoured balsamic vinegar because it changes the colour and sweetness of the ketchup.
Regular hamburger buns work well, but brioche buns make the finished sandwich sweeter and richer. Add sliced pickles or thinly sliced onions when you want more acidity and crunch.
FAQ
Is this made with ground beef?
No. This recipe uses a whole steak that is seared, roasted, rested and sliced. Ground beef requires a different cooking method and should not be cooked according to the steak instructions.
Why is the steak finished in the oven?
The oven heats the centre more gently than leaving the steak over direct stovetop heat. This is especially useful for a thick steak because the exterior can brown without becoming excessively dark before the centre is cooked.
Can I prepare the ketchup ahead of time?
Yes. Prepare it in advance, cool it completely and refrigerate it in a covered container. It will become thicker when cold, so stir in a small amount of water if needed before serving.
Why did my cheddar sauce become grainy?
The heat was probably too high, the sauce boiled after the cheese was added or the cheese was incorporated too quickly. Use finely grated cheese, low heat and gradual additions.
Can the cheddar sauce be reheated?
Reheat it gently over low heat while stirring. Add a small splash of milk or cream to restore its pourable consistency. Avoid reheating it at a full boil.
How do I keep the burger bun from becoming soggy?
Toast the cut sides and assemble the burgers immediately before serving. Put the thicker ketchup on the bottom bun, then the steak and cheese sauce. The toasted surface creates a temporary barrier against moisture.
What can I do with the remaining maple ketchup?
Serve it with fries, roasted potatoes, grilled meat or another sandwich. It also works well with a raclette patty melt and creamy cognac-style sauce.
What to Serve With This Burger
For a classic burger plate, serve it with crisp Belgian-style fries or thin homemade shoestring potatoes. Both give the plate the crunch that the soft steak and cheese sauce need.
For something more substantial, try a loaded potato gratin with steak and bacon. It is a much heavier pairing, so serve smaller burger portions.
For more handheld meal ideas, browse these homemade sandwiches and wraps. A juicy chicken burger with Dijon sauce is a useful alternative when you want a lighter protein, while a chicken, bacon and pickle grilled cheese keeps the same rich, toasted-sandwich feeling.
