Try to use this code in your controller. It's for specific product. If you want to add multiple products. Then, you need to save multiple product collection in $product variable. 

protected $formKey;
protected $_productFactory;
protected $_cart;
protected $messageManager;
protected $_url;

public function __construct(
    \Magento\Framework\App\Action\Context $context,
    \Magento\Framework\Data\Form\FormKey $formKey,
    \Magento\Framework\UrlInterface $url,
    \Magento\Framework\Message\ManagerInterface $managerInterface,
    \Magento\Catalog\Model\ProductFactory $productFactory,
    \Magento\Checkout\Model\Cart $cart
) {
    parent::__construct($context);
    $this->formKey = $formKey;
    $this->_url = $url;
    $this->messageManager = $managerInterface;
    $this->_productFactory = $productFactory;
    $this->_cart = $cart;
}

public function execute()
{
    $product = $this->_productFactory->create()->load($productID);
    if ($product) {
        foreach ($product as $key => $value) {
            $custom_option_value = '';
            if (isset($value['super_attribute']) || !empty($value['super_attribute'])) {
                $custom_option_value = $value['super_attribute'];
            }
            $this->addCartProduct($value['id'], $value['qty'], $custom_option_value,$product);
        }
        $this->_cart->save();
    }
    $this->messageManager->addSuccess('Shopping cart updated succesfully.');
}

public function addCartProduct($productID, $productQty, $custom_option_val,$product)
{
    $info = new \Magento\Framework\DataObject(
        [
            'form_key' => $this->formKey->getFormKey(),
            'product_id' => $productID,
            'qty' => $productQty,
            'super_attribute' => $custom_option_val
        ]
    );
    return $this->_cart->addProduct($product, $info);
}

Hope, It will helpful for you.
