Preheat oven to 350°. Line 16 muffin cups with paper liners.
In the bowl of a stand mixer fitted with the whisk attachment, beat eggs and sugar at high speed for 30 seconds. Gradually add oil, beating until combined. Gradually add milk, beating to combine. With mixer on low speed, add sage, orange zest and juice, and vanilla, beating until combined.
In a small bowl, whisk together flour, baking powder, and salt. Gradually add flour mixture to egg mixture, beating until combined, stopping to scrape sides of bowl. Spoon batter into prepared muffin cups.
Bake until a wooden pick inserted in center comes out clean, 30 to 33 minutes. Let cool in pans for 5 minutes.
For glaze: In a small bowl, whisk together confectioners’ sugar and orange zest and juice until smooth. Spoon glaze over muffins. Remove from pan. Garnish with Candied Sage, if desired. Serve warm.
