Blanc said: "Our intention will be to win the match, the same as usual.
"We will not prepare for the match looking for a draw, that is the best way to lose."
Midfielder Samir Nasri agreed, adding: "We have done half the job. It was important to win, and we did that. Now we must concentrate on the final game.
"If we go for a draw, we could fall into a trap, we have to play our game. Bosnia like to play football, so there will be more space, and the 3-0 win gives us confidence."
Florent Malouda and Loic Remy put Blanc's men in control before half-time, and substitute Anthony Reveillere rounded off the win in the second half to boost France's confidence ahead of their final game.
Blanc praised the way his midfield controlled the game.
"We used the ball well even if the final ball was sometimes lacking," Blanc told the French Football Federation's official website.
"The midfielders were very good, (Samir) Nasri, (Yann) Mvila and (Yohan) Cabaye. These three players controlled the game well and when they had the ball, the team and staff were relaxed.
"I am satisfied, it was good preparation (for Tuesday) but we have had problems in terms of injuries. Patrice Evra and Adil Rami felt pain at the back of their thighs, Yohan Cabaye tried to start the second half but his ankle was no good.
"So things happened which forced us to change the strategy for the second half. We will have to see how the injuries develop and how they react."
Marseille striker Remy, who played off main frontman Bafetimbi Gomis in what Blanc described as "a flexible 4-4-2 formation", said: "You could see how this set-up works, with Bafe as the focal point while I like to play deeper, with Yohan Cabaye and Samir Nasri providing good passes.
"The team is in good form, we are on an unbeaten run, but we know Bosnia are just behind and they also want to qualify. We are in a strong position, it is up to us to make it happen and to not slacken off."
