Chef Croux Koplin isn’t just cooking up a storm at Coachella … he’s cashing in big time!

The private chef tells TMZ he and his tight-knit crew of six — including another chef, an assistant and three helpers — pulled in a sizzling $11K during the first weekend … all while bouncing between luxe desert estates and influencer-packed homes.

Croux says he locked down three separate gigs … starting with a marathon booking to cook for 15 to 17 German influencers from Wednesday through Monday across three different private homes.

But that was just the appetizer.

He also catered a 23-person brunch at a private estate in Indio — with none other than former Disney star Kyle Massey in attendance — serving up fresh-baked fruit tarts, pastry puffs, and steak for the VIP crowd.

Another nearby estate brought in Croux for a 20-person spread, where things got even more decadent … guests feasted on truffle scrambled eggs, goat cheese eggs, French toast, chicken apple sausage, hickory bacon, Mediterranean grilled veggies, and a homemade feta whip dip.

And get this … one of those gigs basically came out of nowhere. Croux says a homeowner saw his crew in action while they were cooking for the German influencers … flagged down one of his team members mid-shift, and locked them in for a booking right then and there.
