Since everyone has complicated their answers with functions and classes, I'll throw in this simplified answer. The \Slim\Http\Response can do it for you like this:

$app = new \Slim\Slim();

$app->get('/something', function () use ($app) {
    $response = $app->response();
    $response['Content-Type'] = 'application/json';
    $response->status(200);
    $response->body(json_encode(['data' => []]));
});

$app->run();

As you're most likely only returning JSON data it might be a good idea to make an appropriate middleware, see http://www.sitepoint.com/best-practices-rest-api-scratch-introduction/.
