You need to embed your response in the callback to the query. Since the call is asynchronous, sending the response earlier will terminate the call stack never waiting for the webapi(Behaviour may vary).

controller.delete = (req, res) => {
    pool.query('DELETE FROM RECIPES WHERE ID = $1', [req.params.id],(err, result) 
     => {
         // error handling can be done accordingly
        return res.redirect('/');
    })

}
