Let's Be Frank includes covers of songs notably performed by Sinatra and also features one original composition.

She was originally approached by producer Don Was following her televised performance at Frank Sinatra's 2015 "100th Birthday" tribute.

In an interview with iHeart Radio, Yearwood explained that her mother was fond of Frank Sinatra and for that reason, she "grew up" listening to him.

Yearwood commented in 2019 that she not want the song to appear on Let's Be Frank because she feared it would disrespect the music of Sinatra.

Stephen Thomas Erlewine of AllMusic called the album not exactly "the kind of comeback most observers would've expected from Trisha Yearwood."

Erlewine went on to call the record a "well-balanced songbook" that included diverse arrangements and song choices.

[7] Kevin John Coyne of Country Universe gave Let's Be Frank four of five possible stars in his review.

Coyne later concluded his review of the album by saying, "Let's Be Frank is a delightful detour, and while it doesn't curb the hunger for more country music from the greatest female artist of the greatest generation of female artists, it is chock full of reminders of how she earned that distinction in the first place.

[10][11] Let's Be Frank marked Yearwood's first solo album since 2007's Heaven, Heartache and the Power of Love and first to chart as well.
