Smoked Bottom Round Roast

Ingredients

• 1.36 kg (3 pounds)beef bottom round roast
• 60 ml (¼ cup)yellow mustard
• 15 ml (1 tablespoon)kosher salt
• 10 ml (2 teaspoons)black pepper
• 15 ml (1 tablespoon)garlic powder
• 15 ml (1 tablespoon)onion powder
• 15 ml (1 tablespoon)brown sugar
• 7.5 ml (½ tablespoon)chilli powder
• 7.5 ml (½ tablespoon)paprika
• 2.5 ml (½ teaspoon)cayenne pepper

Instructions

1. 1

   Bring to room temperature

   Take the roast out of the fridge 40 minutes before cooking so it can come to room temperature.

2. 2

   Season the roast

   Whisk the black pepper, garlic powder, onion powder, brown sugar, paprika, chilli powder, cayenne pepper and kosher salt together in a bowl. Coat the whole roast with the yellow mustard, then press the dry rub into the mustard all over. Set it aside while you preheat the smoker.

3. 3

   Preheat the smoker

   Heat the smoker to 107°C (225°F).

4. 4

   Smoke the beef

   Put the beef in the smoker and close the lid. Smoke for about 2 hours, until its internal temperature reaches 49°C (120°F) for rare, 52°C (125°F) for medium-rare or 54°C (130°F) for medium.

5. 5

   Rest and raise heat

   Take the roast out of the smoker and tent it with foil. Let it rest while you raise the smoker temperature to 218°C (425°F); you can also use an oven for this step.

6. 6

   Sear to finish

   When the smoker reaches temperature, return the roast to the rack and sear it for about 5–15 minutes, according to your preferred doneness. The target internal temperatures are 54°C (130°F) for rare, 57°C (135°F) for medium-rare and 60°C (140°F) for medium.

7. 7

   Rest and slice

   Transfer the roast to a cutting board and leave it to rest for 15 minutes before slicing it thinly.

8. 8

   Serve the roast

   Enjoy!

What is smoked bottom round roast?

Bottom round is a lean cut of beef from the hindquarter, cooked here low and slow in a smoker before a final high-heat sear. This American-style barbecue approach builds smoky flavour while the finishing step adds a browned exterior.

Mustard helps the seasoning cling to the surface, and the mix of savoury spices, brown sugar and cayenne gives the outside a balance of warmth and mild sweetness.

Nutrition and macros by portion

The nutrition label shows one serving as written: 436 calories, 45g protein, 6g carbs, 27g fat.

The beef supplies most of the protein and fat, while the brown sugar and small amount of mustard contribute most of the carbohydrates. Pair a portion with vegetables or salad, and add potatoes or bread if you want a more filling plate.

Why mustard and a dry rub work

Mustard coating: Spread it over the entire roast so the seasoning has an even surface to stick to. Its role here is to help the rub adhere.

Spice blend: Salt, pepper, garlic and onion powders provide the savoury base, while paprika, chilli and cayenne bring colour and heat. Brown sugar adds a touch of sweetness to the rub.

Getting the doneness right

Temperature checks: Use a meat thermometer to check the centre of the roast rather than relying on the clock alone. The recipe gives a smoking-stage target and a higher final target after searing for each doneness.

Carryover cooking: Keep the roast's resting time in mind when checking temperatures, as the recipe includes a rest after smoking and another 15-minute rest after searing.

The two-stage cooking method

Low-temperature smoke: Cooking at 107°C (225°F) gives the roast time to take on smoke before the final sear. The stated smoking time is about 2 hours, but use the internal temperature as the cue.

Hot finish: Raising the smoker to 218°C (425°F) creates a shorter, hotter sear. Keep a close eye on the roast during the 5–15-minute finish, since the time varies with the desired doneness.

Resting and slicing

First rest: After smoking, tent the roast with foil while the smoker heats up. This is the pause built into the method before searing.

Thin slices: After the final 15-minute rest, slice the beef thinly across the grain where you can identify its direction. Thin cuts make this lean roast easier to portion and serve.

What to serve alongside it

Fresh sides: A crisp green salad, slaw or steamed green vegetables can bring freshness to the plate. These also pair well with the roast's smoky, peppery crust.

Hearty sides: Serve it with potatoes, bread or grilled vegetables for a more substantial meal. Keep any sauces on the side so the seasoning on the beef remains prominent.

Recipe notes & tips

• Take the roast out of the fridge 40 minutes before cooking, as directed, to bring it towards room temperature.
• Coat the entire surface with mustard so the dry rub can stick evenly.
• Use a thermometer to check the internal temperature at both the smoking and searing stages.
• Stay nearby during the final sear, as it may take anywhere from 5 to 15 minutes.
• Rest the roast for the full 15 minutes after searing before slicing.
• Slice thinly for serving, cutting across the grain where its direction is clear.

Variations

• Adjust the heat: Reduce the cayenne for a milder crust or increase it slightly for more kick.
• Use an oven finish: Follow the recipe's option to sear in an oven once it has reached 218°C (425°F).
• Change the smoke: Use a different smoking wood suited to your smoker for a different smoky character.
• Make sandwiches: Serve thin slices in bread or rolls with salad or slaw.
• Serve with sauce: Offer barbecue sauce at the table rather than changing the seasoning on the roast.

Common mistakes to avoid

• Skipping the thermometer: The cooking time is approximate, so check the roast's internal temperature for the stated doneness cues.
• Uneven seasoning: Coat the whole roast with mustard and press the rub over all its surfaces.
• Rushing the sear: Let the smoker reach 218°C (425°F) before returning the roast to the rack.
• Over-searing: Check the temperature during the 5–15-minute finish so the roast reaches your chosen target without overshooting it.
• Slicing too soon: Leave the roast to rest for 15 minutes after searing before cutting.
• Thick slices: Slice the roast thinly for serving, cutting across the grain where possible.

How to store

Refrigerate leftover beef in a covered container within 2 hours and use within 3–4 days. Reheat gently until hot, taking care not to cook the lean slices for longer than necessary.
