Essex lost their last six wickets for just 39 runs as Northants fought back on the opening day at Wantage Road.
The visitors looked well-placed at 237-4, but the dismissal of New Zealander Jesse Ryder for 87 sparked the collapse as Essex were all out for 276.
Earlier Nick Browne hit 58 before falling to pace bowler Rory Kleinveldt (3-59) while Rob Keogh took 3-35.
Northants began their innings solidly as they finished the day on 43-0 with Stephen Peters and Rob Newton unbeaten.
Ryder made the most of the good batting conditions, surpassing 7,000 career first-class runs before he was caught by Peters off Steven Crook 13 runs short of a 21st first-class century.
Northants bowler Rob Keogh:
"The pitch is quite dry for the first day, probably only going to get worse as the game progresses so hopefully the boys can stick in and we will try and bat once on this wicket.
"I've been working hard on my spin over the last couple of years and to lead the 1/8spin 3/8 attack is always nice and to get a few wickets on day one is also very pleasing.
"Now I've got more of an opportunity to bowl it's nice and hopefully the more bowling I get and the more wickets I take I can keep that tag as spinner."
Essex batsman Jesse Ryder:
"We've been talking about trying to score some runs, bat time and I guess we've come up on a good pitch after a terrible one we played on, so we get bowled out for 270 is quite disappointing really.
"They've got off to a flyer so we're going to have to come back and put in some hard yards to get back in this match.
"It's pretty flat so we're going to have to turn up and bowl the best we can."
