Jennifer López‘s personal chef, Kelvin Fernandezknows a thing or two about serving up flavorful dishes.

While the “Jenny From the Block” singer, 53, is known for her healthy diet, Fernandez previously told Us Weekly that he goes all out for her children, 15-year-old twins Max and Emme, whom she shares with ex-husband Mark Anthony. (Lopez has been married to Ben Affleck since July 2022.)

“I have the free reign of what to cook, so in the morning for breakfast I get crazy with the kids,” the chef exclusively told Us in 2020, noting that he whips up “Captain Crunch-crusted French toast and eggs Benedict.”

Lopez, for her part, “is such a hard worker,” Fernandez gushed to Us at the time. “When she puts her mind to something, it’s incredible how much it can be accomplished. When she wants something healthy, she’ll stick to it.”

Now, just in time for summer, the culinary expert is giving Us his tips — and exclusive recipe — for the perfect grilled steak (and a scrumptious-sounding side of parmesan mashed potatoes).

Before getting down to business, Fernandez recommends cleaning and seasoning your grill, as “excess oil will create flare-ups and affect the flavor of your steak,” he tells Us. It’s also imperative to temper the meat — it goes with a 1.5-lb. bone-in ribeye steak — meaning that it sits at room temperature “for no more than an hour” prior to grilling.

In fact, “patience is a virtue” when it comes to grilling the ideal steak, Fernandez notes, explaining that once it hits the grill, try to resist the urge to poke it or move it around.

“Resting does wonders for a steak — no foil tent needed. Fiber relax. Juices spread,” the cook shares. “Colors are recalibrated and flavors are retained.”

Tips for Grilling the Perfect Steak

Temper the Meat
Temper your meat before it hits the grill. Allow it to sit at room temperature for no more than an hour before you start grilling. This will help with even cooking time.

Season with Authority
A little salt and pepper goes a long way. Don’t forget to season all sides of the meat, including the fat side, as well.

Leave the Steak Alone
Once the steak is on the grill, let it be. Don’t poke it, touch it or move it. The key is a beautiful crust.

Let the Meat Rest
Resting does wonders for a steak — no foil tent needed. Fiber relax. Juices spread. Colors are recalibrated and flavors are retained. Remember: Patience is a virtue.
