Why You’ll Love this Rotisserie Prime Rib with Beef Tallow Injection

The thing that really knocks this prime rib out of the park is South Chicago Packing Company’s Wagyu Beef Tallow. Whether you get choice grade or prime, you have to add a ton of flavor to the meat with the injection. That Wagyu Beef Tallow makes this meal more juicy, more flavorful and more delicious.

Rotisserie Prime Rib and Beef Tallow

If you are curious about the health benefits, wagyu beef tallow has balancing levels of Omega-3 and Omega-6 essential fatty acids. Not that you needed another excuse to drench your steak in it!

This beef tallow can take even the lesser cuts of meat and make that delicious. The reason is: fat is flavor. That beef tallow is rendered fat off wagyu steaks. Add that to just about any cut of beef and you have instantly made it prime grade meat.

What is Wagyu Beef Tallow?

Beef tallow is rendered beef fat, so it usually has more of a buttery consistency. Typically used as cooking oil to prepare steak and fries and enhance the flavor of the dish.

It remains solid at room temperature but melts when put into a cooking pan. And like I mentioned above, beef tallow has balancing levels of Omega-3 and Omega-6 essential fatty acids.

Rotisserie Prime Rib with Beef Tallow Injection Instructions

Let’s begin by heating up the wagyu beef tallow so it can be injected into the Prime Rib easier. Once warm, add it to your injector and inject throughout the whole prime rib. In my opinion, you cannot add too much of the beef tallow just add about 1 cup.

Next, use any leftover beef tallow to lather the outside of the prime rib as your binder. This will create an amazing outside crust as the fat will render from the coals and caramelize really nicely.

Adding the beef tallow

Mix together your salt, pepper, garlic powder and chipotle powder for your seasoning. I like to use finely ground seasonings as I believe they make the best bark on meat, but you can also use whatever rub you like. Use your favorite beef rub on the recipe as it will only make it taste better to you!

Seasoning the Rotisserie Prime Rib

Finally, we can skewer the prime rib with the rotisserie skewer. Try to make it through the thickest part of the meat and secure it as best as possible. From here, we will set the Rotisserie Prime Rib to the side and get the grill started.

Beginning Stages of Cooking

I like to give my grill about 20-30 minutes to truly warm up to temperature. I’m adding some lump charcoal to a kettle style grill making sure the heat gets to about 325F; however, use whatever you prefer. I want to cook this Rotisserie Prime Rib slowly, but still have some heat to get a nice outside crust. 

Adding the Rotisserie Prime Rib to the Grill

With your grill, try using a two zone cooking method. This means that you have one half of the grill with coals/heat and the other half empty. I will add my Rotisserie Prime Rib to the empty side of the grill so that it cooks evenly and does not create a ton of flare ups.

Add your Rotisserie Prime Rib to the grill and then begin cooking. Cover the grill with a lid and cook for about 2ish hours until the steaks are 120F internal.

Make sure to check on the steak every 15-20 minutes to make sure it’s not burning or causing any problems. Once the Rotisserie Prime Rib is done, pull it off, cover it and let it rest for 20 minutes.

Making the Bourbon Mushroom Cream Sauce

For the sauce, we will rearrange the grill for direct cooking at a medium-high heat. Add a cast iron skillet to the grill then begin “sweating” your mushrooms in hot Beef Tallow.

What is “sweating” mushrooms? Mushrooms have a lot of moisture, so if we do not cook them by themselves they will become soggy and add too much water to the sauce. We will cook out the water so all we are left with is a powerful flavor punch of mushrooms.

Letting the Mushrooms "sweat"

Once they are “sweated” out, we can caramelize some garlic paste and then deglaze with bourbon. You want to be careful with the deglazing part as the skillet might catch on fire! This is totally normal, and the fire will go out once all the alcohol in the bourbon has burned off.

Finish the sauce by then adding the beef broth, heavy cream, salt and pepper. Let that sauce simmer over a little lower heat until fully thickened. Once you have a nice thick & creamy sauce, you can pull the sauce off and keep it warm.

Serving the Rotisserie Prime Rib with Beef Tallow Injection

When everything is done cooking, slice your steaks up and serve with the Bourbon Mushroom Cream Sauce on the side or other the top!

I like to garnish with a little chopped parsley for some color, but serve with whatever you like. I think some mashed potatoes and green beans would go perfectly for this meal; however, choose whatever you enjoy!

How to Store Rotisserie Prime Rib with Beef Tallow Injection

If you find yourself with some leftovers, then lucky you. You can store them in an airtight container in the fridge for 3-5 days!

To reheat, just pull them out, place them on a baking sheet and stick them in the oven to reheat for about 10-15 minutes until hot.

There’s nothing like a prime rib, thanks to our beef tallow courtesy of South Chicago Packing Company.

Ingredients 

Steak:

  • 3 Bone Prime Rib Roast
  • 2 tbsp Kosher Salt
  • 2 tbsp Black Pepper
  • 1.5 tbsp Garlic Powder
  • 1.5 tbsp Chipotle Powder
  • 1 cup South Chicago Packing Wagyu Beef Tallow melted

Bourbon Mushroom Cream Sauce:

  • 1 tbsp South Chicago Packing Wagyu Beef Tallow
  • 2 cup Sliced Mushrooms
  • ¼ cup Beef Broth
  • ¼ cup Heavy Cream
  • 1.5 tbsp Garlic Paste
  • 2 tsp Black Pepper
  • 2 oz Bourbon
  • Kosher Salt to taste

Instructions 

  • Begin by injecting the Prime Rib with the warmed South Chicago Wagyu Beef Tallow all over. Next, lather the outside with any leftover beef tallow as a binder. In a bowl, mix the salt, pepper, garlic and chipotle powder. Season your prime rib thoroughly, then carefully add your rotisserie skewer and secure it. Set to the side to set up your grill.
  • Preheat your grill to a medium heat temperature (about 325F). For fewer flare-ups, try using a two-zone rotisserie method where there is one side with the heat and the other with the rotisserie. Additionally, keep adding wood or charcoal to maintain temperature as needed.
  • Add your skewered prime rib to the grill and turn on your rotisserie. Cook for about 2 hours or until the internal temperature reaches 120F internal for medium rare. Once the prime rib is done, pull it off and let it rest for 20 minutes.
  • Reset your grill for direct cooking at 375F. Add a cast iron skillet and melt your South Chicago Wagyu Beef Tallow. Add your sliced mushrooms and cook for 5-7 minutes until they are golden brown. Next, add your garlic paste and cook for 1-2 minutes, then deglaze with your bourbon. Add your beef broth and let simmer for 3-4 minutes. Finally, add your heavy cream and bring the fire down to 300F. Let simmer until the sauce has thickened (about 10 minutes) over a low simmer. Make sure to stir frequently. Once done, pull off the heat and keep warm.
  • Slice your prime rib, top with the mushroom bourbon cream sauce and chopped parsley. Serve and enjoy!
