Make the Steak Marinade

I like to make this first thing so it can be getting good and happy while the steak is getting cut up.

This recipe is enough to marinade about 3-4 cut up steaks. If you are doing more than that, just double the recipe so you'll have plenty.

Jeff's Fantastic Steak Marinade

  • ¾ cup lemon lime soda (Sprite, 7-Up, Sierra Mist, etc.)
  • ¼ cup soy sauce
  • 3 TBS apple cider vinegar
  • 2 TBS Worcestershire sauce
  • 2 TBS Jeff's original rub

Place all of the ingredients into a mixing bowl and stir well to combine.

Cut the Steak into Pieces

My 4 medium sized steaks were a little over ½ inch thick.


I didn't measure or stress.. I just cut them into about 3 strips each and then further into pieces about 1-inch wide.


Put the steak into a zip top bag for the marinating process.

Marinate the Steak for 4+ Hours

This is where the marinade does it's magic with the steak and I recommend you allow at least 4 hours for this but overnight would be even better.

Pour that delicious marinade over the top of the steak pieces and seal up the bag pressing the air out of the top of the bag as you go.


Place the bag of marinating meat into the fridge.

About once per hour, move the meat around in the bag to unsettle the ingredients inside the bag and to make sure that everything is getting equal time.

Prepare the Vegetables

You can do this when the marinating process is almost complete.

Peel and quarter the onions then further separate them into stacks of about 3-4 layers as shown.


Cut the squash in half length-wise then into pieces about ½ inch thick.

Put the squash pieces in a bowl and coat thoroughly with my Texas style rub .

Place the Meat and Vegetables on Sticks

Once the meat is finished marinating, take it out of the fridge and pour off the marinade.

The marinade can be discarded.

Pour the steak pieces onto a plate or bowl.


Thread the meat and vegetables onto long wooden skewers in a random pattern or you can do them all the same like I did.


I did meat, tomato, meat, onion, green squash, meat, yellow squash, meat, onion, tomato, meat, meat

You can use any combination you like but this worked well for me.

As the shish kabobs where finished, I placed them on a grill pan.

Smoke the Shish Kabobs

Setup your smoker for cooking at about 230°F (110°C) with indirect heat as usual.

I recommend oak or pecan smoking wood if you have it available or any good smoking wood will work well.

If your smoker utilizes a water pan, I recommend using it to create a moist cooking environment.

Once the smoker is ready, place the skewers of meat and vegetables on the smoker grate and close the door.

Keep a light smoke going for about 20 to 30 minutes. After that it can be finished with heat only.

Total cooking time should be between 45-60 minutes.

Watch the meat carefully and once it reaches a good medium rare or about 130°F (54°C), it is finished and should be removed from the heat right away.


Serve these smoked sirloin shish kabobs right away while they are still warm for the best results.


You can serve warmed barbecue sauce on the side for those who like to dip.

  1. Jeff,
    Hi, I am the guy that talked to you several months ago about Costco Prime Brisket. I know you remember.
    My Costco in Clermont, Florida (about !0 Miles From me now) is opening next month Nov. 14th. We are really happy about it and so are all of Clermont and surrounding communities!
    Just curious to know the next time you go to your Costco if you are still getting prime brisket? I don’t mean to be a pain! Thanks in advance and still using your recipes!!! (Only, I do need to lose some weight!!) John Winner PS Haven’t tried the shish kabobs yet …sounds good!

    I always marinate my steaks using a marinade recipe I’ve developed over the last 30 years or so. I might offer a shortcut and save some clean-up: Pour all of your marinade ingredients straight into the zipper bag (liquids first), close it up with some air in it and shake the bag to mix the ingredients, then leave it until you’re ready to use it. No bowl or mixing utensil to clean! It also helps to evacuate all the air you can from the bag after you add the steak to make sure all of the meat is contacted by the marinade. I can usually fit 4 good sized ribeye in a gallon sized bag. I also tend to marinate the vegetables for a bit in a soy, oil and spiced mixture in a separate bag. Cheers!

    1. You can definitely lay these right on the smoker grates if you want to. I often use pans and racks to help keep my smoker grates a little cleaner and/or to make them easy to move from kitchen to smoker but it’s not something you have to do.

  3. Jeff – I purchased your book, and it has been fantastic so far. Great guidance and recipes! I am curious, is your original rub recipe similar to the Big Bald Rub? That was fantastic on some St. Louis style ribs!
