The Huskies (2-0) clicked early on offense and had help on special teams, but it was the defense that kept the pressure on throughout. The Grizzlies (1-1) gained just 31 of their 163 total yards on the ground.
Washington didn't make it much easier in the passing game. Leading by 35 late in the third quarter, cornerback Jomon Dotson intercepted Montana quarterback Reese Phillips and zig-zagged to both sides of the field before completing the 68-yard return to extend the lead to 49-7.
The Huskies racked up nine tackles for a loss, four sacks, two interceptions and two fumble recoveries.
Offensively, Browning completed 22 of 26 passes, including five to senior tight end Will Dissly, who hauled in two touchdowns. Freshman Salvon Ahmed led a balanced rushing attack with 54 yards on nine carries and his first career touchdown, a 1-yarder to push the advantage to 56-7 with 10:37 remaining in the game.
Five different Huskies ran for a touchdown.
After throwing for 381 yards and four touchdowns in a season-opening win over Valparaiso, Phillips struggled against a defense that ranked in the top 20 last season. The senior finished 17 of 28 for 123 yards. Montana was just 2-for-17 on third-down conversions.
Washington made amends for last week's sluggish start and raced out to a 35-7 halftime lead.
A 21-point first quarter set the tone, capped by senior return man Dante Pettis' record-setting punt return as time expired. Pettis eluded four would-be tacklers on an electrifying 67-yard touchdown -- the seventh of his career to set a Pac-12 record.
Browning and running back Myles Gaskin added first-quarter scoring runs for the Huskies. Browning needed less than four minutes to put the Huskies ahead 7-0 on a 1-yard touchdown. In contrast, the Huskies needed 26 minutes before taking their first lead in last week's 30-14 win over Rutgers.
Montana allowed 326 total yards in the half. Sophomore safety Josh Sandry supplied the lone highlight, returning a 36-yard interception for a touchdown to tie the game at 7-7 with 4:56 left in the quarter.
The Grizzlies' next-best scoring chance was spoiled on a fumble at the Huskies 35-yard line with 8:10 to play in the half. Washington's defense made three sacks and allowed just three yards rushing.
Browning closed the half with a 20-yard touchdown pass to Dissly inside the final minute.
