Step 1: Create a block file

namespace {custom namespace}\Block;

class BestSeller extends \Magento\Framework\View\Element\Template
{

    protected $_collectionFactory;
   public function __construct(
       \Magento\Backend\Block\Template\Context $context,
      \Magento\Sales\Model\ResourceModel\Report\Bestsellers\CollectionFactory $collectionFactory,
               array $data = []
   ) {

       $this->_collectionFactory = $collectionFactory;
             parent::__construct($context, $data);
   }


public function getBestSellerData(){

$bestSellerProdcutCollection = $this->_collectionFactory->create()
                    ->setModel('Magento\Catalog\Model\Product')
                    ->setPeriod('month') //you can add period daily,yearly
                   ;

       return $bestSellerProdcutCollection;
   }
}

Getting collection in phtml file from block.

        $bestSeller =  $block->getBestSellerData(); ?>

        <ul>
            <?php foreach ($bestSeller as $product) {
                ?>
