A popular technique to mimic the grill can be done in your very own oven — think of your oven's broiler as a kind of upside-down grill. Using intense, direct heat to char and cook things quickly, proper use of a broiler can lead to a tantalizing, caramelized crust, very similar to outdoor grilling.
A few things to keep in mind when broiling:
Preheat the broiler pan as close to the top of the oven as you can as the best results come from broiling your food only a few inches away from the broiler itself.
Keep the oven door open slightly to let the air flow and avoid trapping the hot air and baking your food
Don't walk away – it's important to keep a close eye when broiling, as foods can quickly go from perfect to burnt due to the high heat (and there's a fire danger with the door open).
