Gas grill vs. Charcoal Grill for Chuck Roast
A gas grill will usually heat up in about 5 to 10 minutes on medium-low, while charcoal grills depend on coals to ash on the outside and turn bright red on the inside.
If you are using one, you will need to place your beef roast 4 to 6 inches from medium-low coals.
Once the grill is ready, remove the roast from the marinating bag and let it reach room temperature (remember you want to cook your chuck roast evenly). It will take anywhere from 40 minutes to 2 hours, once you take it out from the fridge.
You can choose what to do with the leftover marinade. If you discard it, you will miss out on the part where you can baste your roast while it’s grilling and have an extra tender meal.
However make sure you finish up basting the roast well before you take it off the heat – bacteria are still an issue.
Place the chuck roast on the grill, and close the lid to let it cook through. Sear all sides and baste it every 15 minutes to keep it moist while it cooks.
Flip it occasionally and rotate 90 degrees to get the grill mark pattern on the grilled chuck roast.
The internal temperature of the roast should tell you when it’s ready. Use a cooking thermometer to check when it reads 55C / 130 F for medium-rare.
This should take up to 50 min. for a medium-rare chuck roast, depending on the thickness of the roast (you can leave it on for 1 ½ hours or until tender, turning intermittently).
Baste the roast in the last 15 minutes and take it carefully off the grill when it reaches desired doneness.
Wrap it up in aluminium foil and allow it to rest for another 10 minutes before you slice and serve the rich, savoury beef chuck roast packed with flavor!
