Ribs take forever and a day on the grill, but ribs from the oven lack a certain smokiness. Michael Chiarello combines the two techniques for killer flavor and party-day efficiency. The trick is cooking the ribs all the way through in the oven, before anybody arrives, and then, at the last minute, searing them hard on a hot grill. "That way, in like 10 minutes of work, you're pulling fall-apart-tender ribs off the grill and passing them around, and everybody thinks you're a hero," says Chiarello, who got the idea for this pork-infused rib seasoning during a trip to Italy. But don't pull them off the grill too soon: "I think those little charred bits – those sort of burnt ends on the bones or those nasty bits that fall apart in your mouth – are really important."

• 4 full racks baby back pork ribs

For the Milanese Rub
• 3/4 cup coarsely chopped garlic
• 5 tbsp chopped lemon zest
• 3/4 cup kosher salt
• 1 cup loosely packed fresh sage leaves, stemmed
• 1 cup fresh rosemary leaves
• 1 1/2 cups finely minced pancetta
Tip: Put pancetta in a freezer for a half-hour, but not longer, before mincing, to stiffen it up and make it easy to cut.)
• 2 tbsp freshly ground black pepper

Step one
Make the dry rub. Put garlic and lemon zest in a food processor and pulse to combine. Add salt and blend until smooth. Add sage and rosemary; pulse again. Finally, add pancetta and pepper, and process until the mixture looks like a very coarse, moist salt rub. (Don't overprocess, or it will turn gummy.)

Step two
Preheat oven to 300 degrees.

Step three
Sprinkle the rub all over rib racks and press it into the meat with your fingers. (Tip: Leave rub on for 30 minutes or so before cooking.) Stack the racks, one on top of the other, on a roasting pan or baking sheet and put in the oven. While they cook, rotate the stack every 15 minutes by taking them out of the oven and moving the bottom rack of ribs to the top of the pile.

Step four
After one hour, check doneness with what Chiarello calls a "shake test." Using tongs or a kitchen towel, pick up a rack by one end and give it a shake – if it curls over and wiggles, the ribs are cooked; if it remains stiff, put back in the oven and try another shake test in 15 minutes.

Step five
Remove ribs from the oven and let cool to room temperature.

Step six
Place ribs on hottest part of the grill for five minutes per side. Remove from grill, cut into individual ribs, pile on a platter, serve immediately.
