In large saucepan, heat oil over medium heat. Sauté shallots for 2 to 3 minutes. Add stock along with potatoes, parsnips, pear, and thyme. Bring to a boil, then simmer until potatoes and parsnips are fork tender, about 30 minutes. Remove from heat and purée with an immersion blender or in batches in a blender.
Return to saucepan over medium heat; stir in mustard and smoked gouda until combined. Serve immediately.
