How to make Bone Marrow Oklahoma Smash Burgers

Prepare and smoking the bone marrow

In a large bowl, add 4 cups of warm water and 1/4 cup of kosher salt. Mix until completely combined, then add in a tray of ice cubes to cool the water down. Add the bone marrow to the bowl and let it soak overnight (12-24 hours) to remove any excess blood. If you do not have this extra time, try to let it soak for at least 2 hours.

Remove the bone marrow from the salt water, then pat them dry with a paper towel. Spray them with some avocado oil, then season them with salt, black pepper and garlic powder.

Place them on the Ninja Kitchen Woodfire ProConnect XL Outdoor Grill and Smoker and smoke them at 250° F for 30 minutes. I smoked these with an all-purpose blend of pellets that provide bright, sweet smoke flavor to the bone marrow.

Burger and topping prep

Next, prepare the burgers by forming ¼ pound balls – these are the perfect size patties when doing smash burgers. You don’t want them to be too thick because you’re going for thin, crispy patties that will be double stacked. If you are not going to do these as smash burger, form up 1/3 pound burger patties then season the meat with your favorite burger seasoning.

Prepare the onions by thinly slicing it with a mandolin. You want to make sure you have plenty of onions to smash down into the meat for this cook. You can use white onions for stronger flavor or yellow onions for more of a sweet flavor.

Put together your burger sauce in a small bowl by combining mayo, ketchup, mustard and smoked paprika. Mix thoroughly then place in the fridge until it’s time to serve.

Once the bone marrow begins to render down and looks smoked, remove it from the smoker.

Grilling up the Bone Marrow Oklahoma Smash Burgers

Increase the grill to high heat. It’s very important to let it get to temperature because you want great sear on the meat when it’s smashed down.

Place the burger ball down on the hot grill, add a handful of sliced onion to each ball then smash them down with a burger press. Season the smashed patty with your favorite burger rub and let it cook for 3-4 minutes. Be sure to not touch it, this will help form the crust on the meat.

Flip the burger then top each patty with some American cheese and let it cook for another 3 minutes. You can use whatever kind of cheese you want for this.

Remove the burgers from the grill then assemble by double stacking them on a toasted brioche bun, and topping them with the onions, smoked bone marrow and burger sauce.
