Just be careful with that Sunday spaghetti if you grow out a Tom Selleck mustache.

“Blue Bloods” may be coming to a natural conclusion, but its epic Sunday dinners don’t have to end — not so long as its fans have internet access, a dining-room table, and all of the cookware required by the one Wahlberg brother who doesn’t act.

On Monday, October 14, “Blue Bloods” star Donnie Wahlberg’s brother Paul Wahlberg — the Wahlburgers restaurant chain’s chef — will share the first of eight family-dinner recipes, each aligned with one of the CBS procedural’s final eight episodes. And the CBS/Wahlburgers collab is going way beyond burgers.

The Friday, October 18 “Blue Bloods” Season 15 premiere will feature Donnie Wahlberg, Tom Selleck’s mustache, and “a hearty roast beef meal with all the trimmings,” according to a Tuesday press release. Four days earlier, Chef Paul will post an instructional video and written recipe for “a delicious corresponding meal of roast beef, roasted potatoes, green beans, and carrots.”

Each of the recipes and instructional videos will be posted on the Wahlburgers Instagram page, the “Blue Bloods” Instagram page, and the “Blue Bloods” YouTube channel.

For the uninitiated (anyone who isn’t your dad), every “Blue Bloods” episode includes a Sunday family dinner at the home of Selleck’s character, Frank Reagan. He’s joined by his father (Len Cariou), his children (played by Donnie Wahlberg, Bridget Moynahan, and Will Estes) and grandchildren, along with Jamie’s (Estes) wife, Eddie (Vanessa Ray). They eat well.

“As a chef and someone who values the importance of family traditions, it’s an incredible honor to celebrate the legacy of ‘Blue Bloods’ with some Wahlburgers magic,” Chef Paul said in a statement. “The Reagan family’s dinners have always been about more than just the food — they’re about the connections we make around the dinner table in the same way my own family did. I’m thrilled to share these recipes with our fans, and I hope they inspire families and friends to come together, just like the Reagans do every week.”

Wahlburgers is owned by Donnie, Paul, and their third brother, a little-known rapper/actor named Mark Wahlberg. We hope that kid catches a break soon.

Mike Benson, the president and chief marketing officer at CBS, said that “by all accounts” the Reagan family dinners “the heart of every episode” of “Blue Bloods.”

“These Sunday meals have really resonated with the shows’ devoted fans through the years — so I couldn’t be more pleased with our ‘Blue Bloods’ recipes partnership with Wahlburgers and Donnie Wahlberg’s brother, Chef Paul, to honor ‘Blue Bloods’ final season,” he continued. “For the first time, fans — and anyone who loves cooking — can get a preview of the Reagans’ meal to cook for a gathering or possibly eat as their own home-cooked ‘TV dinner’ while watching the episode.”

“Blue Bloods” is executive produced by Kevin Wade, Ian Biederman, Siobhan Byrne-O’Connor, and Dan Truly. It is produced by CBS Studios; “Blue Bloods” airs on CBS and streams on Paramount+.
