I’ve always found the journal Leaven worth checking out. It’s published quarterly by the Religion Division at Pepperdine University, and ‘exists to help fellow Christians think together about the challenges of ministry’.
The current issue is devoted to the story of Joseph in Genesis 37-50, and contains the following articles (available from here):
The Role of Genesis 37:1-11 in the Joseph Novella

The Biblical Testimony of Joseph: the Immanuel Perspective
“God Has Made Me Ruler over Egypt”: Joseph and Moses as Royalty
Joseph’s Unjust Economic Policies in Genesis 47:13-26
What About Judah?
A Good Leader is Hard to Find
