Today we are going to make the most epic of burgers: The Steakhouse Smash Burger. We’re talking a double patty smash burger covered with horseradish mayo, maple bourbon onions and slow smoked prime rib.
Why You’ll Love This Steakhouse Smash Burger
This perfect smash burger is a fun new way to enjoy prime rib and smashed patties! Not only is the cooking process fun, but you can use your favorite toppings to create the best burger that will rival your favorite burger joint!
Get out a large metal spatula and place burgers over medium high heat to create the juicy burger of your dreams. Top with cheese, maple bourbon onions, horseradish mayo, and hamburger buns for the ultimate delicious combo.
I love to make any smashburger recipe out of cubed chuck roast and short rib, although some classic ground beef works just fine too. In this recipe we’re also smoking prime rib, which I flavored with my Tennessee Smoke Seasoning.
I make my own maple bourbon onions with sweet onions, bourbon or whiskey, brown sugar, unsalted butter, my Maple Bourbon Seasoning, and my own horseradish mayo with mayonnaise, prepared horseradish, dijon mustard, hot sauce, and Nashville Hot Seasoning. They are all simple ingredients that combine to create complex flavors.
I finish this recipe with some American cheese and toasted brioche buns for the best smash burgers ever! Although the prep time is only 30 minutes, the cook time is 4 hours long, so keep that in mind. However, it does serve 6 people, so it is well worth your time!
How to Make Steakhouse Smash Burgers
The first step to create our best homemade smash burgers is to grind our own burger meat. Now, you do not need to do this! I usually use a blend of chuck roast and short rib for my own personal burger meat, but classic 80/20 ground beef from your local grocery store will do just the trick to create a delicious beef patty.

That being said, if you do grind your own meat then make sure to keep everything super cold. I like to cube up the meat and add it to the freezer for 10 minutes so that it firms up. This not only helps the grinding process to run more smoothly but also helps to keep unfriendly bacteria away.
Once we have cubed up the chuck and short ribs, add it to your grinder at a medium grind setting. I like to double grind the meat so that it makes it a little smoother and easier for molding. Once ground (or if you have classic ground beef, then start here), we will shape the burger meat into balls about ¼-⅓ lbs in size.
Make enough patties for the whole family to enjoy the Steakhouse Smash Burger, then set them on a tray and place in the fridge until you are ready to grill. Now, let’s move to the next piece!
Prime Rib + Smash Burger
Once the ground meat balls are ready, we will move on to smoking the prime rib. Seasoned with my Tennessee Smoke Seasoning, this prime rib will cook at medium heat (275F) until 120F internal. If you are like me, then you might have a ton of leftover prime rib from the holidays. Feel free to use that instead! Once the prime rib is done, we will pull it off and rest for 30 minutes.
Another key piece to this Steakhouse Smash Burger recipe is making the Maple Bourbon Onions and the Horseradish Mayo. The sliced onions will be slowly cooked over the fire in a cast iron skillet until they are deep brown in color. The maple bourbon seasoning and extra brown sugar will help to give them a sweet and savory flavor that will really compliment the spiciness from the Horseradish Mayo.
We will make the mayo right before serving. Mix together everything in a bowl, cover and place in the fridge. Feel free to increase or decrease the heat level on the sauce depending on your palate.
Let’s Get to Cooking
Next, let’s make the burger patties. Now a word of warning, make sure everything is ready to go for the patties as they will cook really fast. I am speaking from experience. Have your cheese, spatula and gloves ready.
First we will add a bit of oil to our skillet. Next, we add the burger balls and let sear for 30 seconds. Grabbing a large spatula or smash burger press, place a piece of parchment paper over the ball and press the top of the patty down firmly for a good smash. Let cook 1-2 minutes per side.
Once smashed, season each thin patty with salt then repeat with all the other burgers. We will flip the Steakhouse Smash Burgers over and look for that deep brown sear. Add a slice of cheese on top of your thin crispy crust hamburger patty so that the cheese melts. Now we are ready to build our burger!
The Steakhouse Smash Burger
Building the Steakhouse Burger is easy. Start by adding some mayo to the bottom bun, then top that with caramelized onions, 1 or 2 smash patties and thin slices of prime rib. Then, add mayo on the top bun to create that restaurant burger and enjoy!
This is a delicious burger to have with any steak (does not need to be prime rib) or with some leftovers! Cheers!

Steakhouse Smash Burger
- 1-2 lbs Chuck Roast cubed
- 1 lb Short Rib deboned & cubed
- 6-8 slices American Cheese
- 6-8 Toasted Burger Buns
- 2 Bone Prime Rib
- 2 tbsp Tennessee Smoke Seasoning
- 1 tbsp Canola Oil
Maple Bourbon Onions:
- 1.5 medium Sweet Onions thinly sliced
- 1.5 oz Bourbon or Whiskey
- 1 tbsp Brown Sugar
- 1 tbsp Butter unsalted
- 2 tsp Maple Bourbon
- ¼ cup Mayonnaise
- 2 tbsp Prepared Horseradish
- 1 tbsp Dijon Mustard
- 2 tsp Hot Sauce
- 1 tsp Nashville Hot Seasoning
(If grinding your own meat, start here):
- Cube up your short rib & chuck roast meat and then place in a bowl into the freezer for 15 minutes. Keep your meat cold as much as possible in order to prevent contamination. Set up your meat grinder to a medium size grind, and when ready, pull the short rib out of the freezer. It should be cold and firm, but not frozen. If it is frozen, then let it thaw till it is firm.
- Add your meat to the grinder hopper and carefully push it in. Place a cold bowl at the end of the grinder for the meat to fall into. Once the meat is ground, throw it back into the grinder for a second grind. This will help to get it finer and less gritty. Once it is ground the second time, place the meat in a bowl. Grab a handful of meat (around 1/4 lbs… ish) and gently roll it into a ball. Repeat this for 6-8 balls or until you’re out of meat. Place the rolled meat into the fridge until ready to use.
(If you are not grinding your meat, start here):
- Prime Rib: Begin by lathering your prime rib with oil and seasoning with Tennessee Smoke seasoning. Preheat a smoker for indirect cooking at 275F. Add the prime rib to the smoker to cook until it reaches 120F (around 2.5-3 hrs). Once done, let rest for 30-45 minutes. This can also be done with leftover prime rib!
- While the prime rib rests, preheat your fire to a medium high temperature (around 350-375F). Add a small cast iron skillet over the fire about 2 minutes before cooking.
- Maple Bourbon Onions: To the skillet, melt the butter then add the thinly sliced onions and let cook for 10 minutes. Once the onions have begun to brown, add the brown sugar and maple bourbon seasoning. Let caramelize over lower heat for another 5-7 minutes, then deglaze the skillet with the bourbon. Simmer until the bourbon has reduced (about 2-3 minutes), then pull off and keep warm.
- Smash Burgers: Next, kick up the heat on the grill to high heat (around 400F). Add another skillet or large plancha with some oil to the heat. Pull the burger balls out of the fridge and let thaw for 1 minute. Add the ground meat balls to the skillet and season with salt. As the meat sizzles, get out a small piece of parchment paper and a larger spatula/burger smasher. Place the parchment over one ball and then firmly press with the spatula until the burger is “smashed” on the skillet. Repeat this for each burger and let cook for another 1-2 minutes. Carefully flip each burger over and then season the new side with salt. Top each burger with a slice of cheese and let melt for 1-2 minutes. Once melted, pull each burger off and rest.
- Horseradish Mayo: In a bowl, mix together all the ingredients for the Horseradish Mayo until fully mixed.
- Now that everything is ready, let’s start building our burger. Add the Horseradish Mayo to the base burger bun, top that with Maple Bourbon Onions then add a single or double patty burger on top. Thinly slice some of your prime rib and add that next to the burger. Finish with mayo to the top bun. Serve and enjoy!
