    Smoked Rump Roast

    Jump to Recipe Print Recipe

    Learn step by step how to make a smoked rump roast on ANY grill or smoker!

    Whether you're smoking your rump roast on a Traeger or Pit Boss pellet grill, a Weber Kettle, or a Masterbuilt electric smoker, we've got you covered.

    a sliced medium rare rump roast

    A rump roast is a simple, lean beef roast, sometimes labeled as a bottom round roast, although technically is a little different.

    While both cuts come from the hindquarters of the steer, the rump experiences slightly less use than the round, and therefore has more intramuscular fat.

    This makes the rump roast perfect for the smoking low and slow without as much risk of drying out, although we will still need to watch our temperatures closely!

    Unlike our super fatty beef brisket and beef ribs, we are going to smoke and then reverse sear this rump roast more like a steak, or traditional beef roast to a perfect medium rare.

    We are going to cover:

    • How to prep your rump roast for the smoker
    • How to set up different grills and smokers for a smoked rump roast
    • What temperature to smoke your rump roast
    • The best wood choices for a smoked rump roast
    • How to know precisely when your smoked rump roast is finished
    • How to rest, slice, and serve your perfectly smoked rump roast.

    Wow, that's a lot...so let's get smokin'!

    Prepare the Rump Roast for the Smoker

    Thankfully you won't need to do much of anything to your rump roast other than take it out of the package and season it before you smoke it.

    a raw rump roast

    There isn't usually too much exterior fat to trim off a rump roast, but if there is, you can certainly cut off the excess so that the seasoning penetrates the meat a little better.

    Make sure to always use a good boning knife like this one from Mercer so you don't tear up your beautiful beef roast while trying to trim the fat.

    Once the excess fat is trimmed, give it a rub down with a good high smoke point oil so that if you decide to sear it later, the oil doesn't burn.

    We are big fans of flaxseed or avocado oil for searing beef roasts like smoked rump roast.

    Top Seasonings for Beef Rump Roasts

    When it comes to a smoked rump roast, or most beef roasts for that matter such as ribeye roast, you want to keep the seasonings simple and savory.

    a seasoned raw rump roast

    Save the sugary BBQ rubs for your ribs and pork butts, especially since we will be searing this roast later and you'll just end up burning all that sugar.

    If you REALLY want to use a sugary BBQ rub like Blues Hog, one of our favorites for low and slow cooking, then skip the searing step at the end.

    For our recipe below, we use a mixture of kosher salt, black pepper, paprika, onion powder, cayenne, and fresh minced garlic to form our exterior bark.

    If you want a quick store bought rub with NO sugar, then try Bad Byron's Butt Rub.  If you read our recipes often, you will see we recommend this one often for sugar free seasoning.

    We also really like Meat Church's Holy Cow Rub for rump roast. It contains no sugar as well.

    We oil up and season the rump roast for at least 2 hours, preferably overnight, wrapped in plastic wrap in the refrigerator, before placing it on the smoker.

    This gives the salt loads of time to penetrate the meat and really flavor it all the way through.

    Best Smoking Wood Choices for Rump Roast

    For a big piece of beef like a smoked rump roast, go with something like hickory, alder, or pecan that will compliment the beef well.

    If you want to keep it simple and straightforward, choose a lighter smoking wood like oak, apple, or peach.

    Just know that these lighter fruitwoods may not impart as much smoky flavor into the beef as they might with chicken or fish.

    When in doubt, you can always mix and match your choices together.

    Make sure you are using hardwood pellets in a pellet grill, wood chips in an electric smoker, and wood chunks when smoking on a charcoal grill.

    Best Times and Temperatures for Smoking a Rump Roast

    You will need to watch both your cooking temperature and internal temperatures carefully when smoking the rump roast.

    Smoker Temperature

    We recommend setting up the grill or smoker to cook at 225-250°F INDIRECTLY.

    The rump roast is still somewhat lean compared to a lot of traditional BBQ meats, and will cook relatively quickly compared to a big fatty brisket or Boston butt for pulled pork.

    So we are keeping the temperature low to not only keep the meat moist but to also impart as much smoke flavor in the brief time it takes to cook as we can.

    Target Internal Temperature

    You HAVE to use a good instant read meat thermometer to know where the internal temperature is of your smoked rump roast.

    putting a raw rump roast on a smoker with a temperature probe

    Ideally you want a good leave in probe thermometer like the ThermoPro as well as a second instant read to spot check different depths and areas on the roast.

    ThermoPro TP08 300FT Wireless Meat Thermometer with Dual Probe

    While we have used and recommended ThermoPro for years, lately we have also become big fans of the MEATER leave in thermometer.

    It is extremely accurate and has an incredible 165 foot Bluetooth range and works right with your smartphone so you don't need to carry a separate controller around with you like many other remote thermometers require.

    It's got a great free app that is constantly being updated and even has an algorithm to predict how much longer your type of meat will take to cook based on cooking temperature, target temperature, current internal temperature.

    It's like a GPS for your meat!

    We are going to slowly bring the internal temperature up to about 125°F, then sear it as hot as we can for about 2 minutes on every side until the internal temperature hits about 131°F and then remove it from the grill or smoker.

    You can't do all this without accurate thermometers.  There is very little room for error when smoking a beef roast like a rump roast.

    For spot checking throughout the cook, we are particular fans of this one from ThermoPro because of its durability and affordable price.

    Everyone from beginner smokers to competition cooks need to use instant thermometers to consistently make great food.

    So keep them handy and use them often.

    Cooking Time

    A general guide is that most beef roasts take about 25-30 minutes per pound to smoke at 225°F.

    So plan on a 5 lb rump roast to take about 2 to 2.5 hours to cook to medium rare.

    Then add in your searing time and about 30 minutes to let it rest after cooking it before slicing.

    Unless you want all those delicious juices running all over your cutting board instead of staying in the meat where you want them, you need to set aside time for the smoked rump roast to rest.

    Reverse Searing Smoked Rump Roast

    "Reverse Searing" is just a fancy term for searing your meat at the very end, once it is pretty much all the way cooked through, in order to get a nice crispy exterior crust that you sometimes just can't get from low and slow smoking alone.

    Once the internal temperature of the smoked rump roast reaches about 125°F, you are going to move it with a good pair of long handled BBQ tongs to the hot part of the grill, some Grill Grates on a pellet grill, or even just a hot cast iron skillet or griddle.

    Check Price on Amazon

    You will need to keep turning the smoked rump roast to get each side seared evenly.

    The hands down BEST way to sear meat on a pellet grill, especially an older model that may not have a built in searing feature like the newest Pit Boss Pro Series and Traeger Ironwood Series, is to use a Grill Grate.

    These handy aftermarket pellet grill accessories use the ambient heat of a pellet grill to create a searing hot surface on which to finish your meat hot and fast.

    We love them for finishing smoked pork chops, steaks, and hamburgers on a pellet grill such as a Pit Boss, a Traeger, or a Camp Chef.

    Make sure to measure and choose the right size for your specific pellet grill.

    Resting and Slicing a Rump Roast

    You will then remove the smoked rump roast from the hot grill, Grill Grate, or skillet and let it rest on a cutting board.

    Do not cover, wrap, or tent with foil when you let medium rare beef rest or it will continue to steam and over cook!

    Let the smoked rump roast rest for about 20-30 minutes before slicing.

    Make sure to use a good meat slicing knife if you want those ultra thin deli style slices for the best roast beef ever.

    We particularly like this meat slicing knife from Mairico.

    • IMPECCABLE PERFORMANCE: The long, ultra sharp blade is engineered to deliver highly precise cuts with minimal effort.
    • PROFESSIONAL DESIGN, SUPERB QUALITY: Most desirable length by professionals. Sharp blade with premium stainless steel engineered to excel on all cuts of meats, including big roasts. It is also designed to last.
    Check Price on Amazon

    The outside slices will be more done than the very center if you have people in your house who prefer various levels of doneness to their beef.

    If you are serving your smoked rump roast as a dinner, go ahead and slice thicker ¼" slices to serve with a jus, horseradish, or maybe a rosemary cream sauce.

    Make sure to only slice what you plan to eat immediately in order to keep the beef roast as moist as possible.

    Serving Suggestions

    You can't go wrong with a flavorful jus to make a smoked French dip or a traditional horseradish cream to cut through the richness of the smoked rump roast beef.

    For sides, we especially like asparagus, our yummy smoked carrots, or sticky smoked sweet potatoes.

    Hope you enjoy!

      Made this for Memorial Day weekend '24. Turned out delicious; my wife and our friend really, really liked it! I will definitely come back to this recipe for future smoked rump roasts too. Guidance on temperature and the reverse seer were spot on. I did not follow the instructions for making the au jus correctly but it turned out well enough and was a great sauce for the roast. The next time I do this I will definitely follow the instructions for making the au jus more carefully and the one other thing I would experiment with will be to reduce the amount of salt used to season the roast by half. I smoked a 3lbs roast instead of a 5lbs one referenced in the recipe. I cut the quantities in half to suit the cut size I was working with. I have used plenty of salt and pepper in other smoked beef recipes too and they all seem to use more salt for tenderizing that ends up in the bark after smoking. I know salt is important for the tenderizing process but I think for my taste I'll try cutting the quantity in half and still use the other spices in quantity as spec'd out

      Thanks,
      pjg
