Jamie Vardy scored a second-half penalty double as Leicester condemned West Brom to a disappointing return to the Premier League.
After goalkeeper Sam Johnstone twice came to the home side's rescue with saves to deny Harvey Barnes in the first half, new signing Timothy Castagne broke the deadlock when he nodded home a far-post cross from fellow Belgian Dennis Praet nine minutes after the restart.
Vardy, last season's Premier League top scorer, then got up to score from the spot after being dragged back by Kyle Bartley as he chased into the box to support a move that saw Johnstone deny former Baggies loanee Barnes for a third time.
The 33-year-old repeated the feat 10 minutes later after Dara O'Shea tripped James Justin.
As playmaker James Maddison made a second-half appearance off the bench after recovering from a hip operation that crucially caused him to miss the end of the season, it was a good day for manager Brendan Rodgers and his team, who were winning this particular fixture for the fifth time in a row.
For West Brom, it was a brutal reminder of the task they face merely trying to stay in the top flight.
All three promoted teams lost on the opening weekend and - like Fulham, who were beaten by a similar scoreline against Arsenal on Saturday - there are early question marks over whether they have the quality to survive.
