Even if it’s winter or there isn’t a holiday in sight, there’s no reason to stop using the grill! It’s such a great tool for turning the ordinary into dinner party fare. There’s not much you can do in the kitchen that you can’t do on a four-burner TRU-Infrared™ grill.

We’ll walk through the preparation step-by-step, or you can scroll down for the printable version.

Bourbon Glaze Ingredients

Bourbon Glaze Ingredients

Anyone can do standard potatoes with roast beef, but this dish shines with root veggies of other types: a mix of carrots, rutabaga, parsnips and onions. The secret to roasting all these veggies is to cut them into similarly sized pieces. After peeling and cutting all the root veggies, they get tossed in a mix of equal parts molasses and bourbon, then put onto a grill pan and added to one side of the middle grates on the Char-Broil® TRU-Infrared™ grill about an hour before dinner. Preheat the grill about 10 minutes prior to 425°F with the middle burners then turned off.


Roasting Root Veggies

Starting with the marinade, it’s easy to put together. Soy sauce, bourbon and vegetable oil are the main ingredients with a bit of grainy mustard and some salt and pepper. All the ingredients go in a blender for about 30 seconds on high, then go over the roast of choice in a zip-closed bag with a cipriani onion, quartered, and a couple smashed garlic cloves. The bag, once closed, goes in a shallow pan in the fridge for up to 6 hours, turning ever hour to ensure good coverage.

After the veggies are on, take the roast out of the fridge and remove it from the baking dish/shallow pan. Add in one medium to large onion, cut into several pieces, along with 3-4 carrots, 2 celery stalks and 3 smashed garlic cloves. The veggies should all be cleaned and loosely chopped, but they don’t need to be peeled. The roast goes right on top of the bed of aromatics and the marinade is added, along with some salt and pepper. With that, the whole thing goes onto the middle grates of the grill for about 45 minutes or until the roast hits about 130°F internal temperature. The roast needs to rest, under foil, for 15 minutes before slicing.

For Sliced Beef:

About 30 minutes before dinner, put 1/4 cup bourbon and 1/4 cup molasses in a sauce pan over very low heat to slowly reduce by at least half. This is a great glaze for the root veggies, in moderation.

Roast Beef Dinner

For Roast Beef Dinner:

After the roast rests 15 minutes slice it thin, adding a bit of the liquid in the bottom of the dish with a helping of veggies drizzled with the bourbon glaze. For a bit of an extra oomph, I also added some bourbon barrel stave pieces on the hot grates to add smoke flavor, always a welcome addition.
