There's no shortage of holiday cheer in the Shelton-Stefani household.

"I've already got my turkey bought. I got two turkeys put away in case there's a shortage for some reason. We can do our whatever weird one we come up with, and then Gwen can make the [traditional recipe]," Blake Shelton — whose latest single "Texas" became the most-added new song on country radio after its release — tells PEOPLE exclusively about celebrating the upcoming holiday with wife Gwen Stefani.

Over the years, the couple have headed to Oklahoma with their extended families for a Thanksgiving extravaganza.

"We go all out for Thanksgiving. We've got a huge family, so we feel good about making a bunch of food. Normally, it's like, 'Oh damn, we're already out of stuffing? How can that possibly be?'" says Shelton, 48. "We're excited about it."

While gathering loved ones under one roof can be chaotic, the country superstar says they only follow one rule: "Never say no to any kind of food. Whatever you want to try, I'll try it. Just bring it on."

And though it's rare to have any food left at the end of the night, Shelton says he and Stefani get creative when it comes to repurposing their sides.

"I heard a guy on the radio a couple of years ago talk about if you have leftover stuffing, the next morning put it in your waffle iron and make those stuffing waffles," he says. "Now I do that. Now I make enough that I know there'll be some leftover."

Shelton and Stefani have both been busy promoting new music, but the star says he's looking forward to getting some downtime with loved ones.

"I love the fall. I love watching football. I'm still a huge Arizona Cardinals fan, and that's my perfect day," he says. "Last Sunday I told Gwen, 'I'm having the best day.' We had family over, cooked a good meal. My team won. It was like, 'I want to have this day every day for the rest of my life.' Just laid-back family and watching football."
