Heat the oven to 400°F. Halve the squash lengthwise on a stable board, remove seeds and place halves cut-side up on a baking tray.
02 -
Brush all four cut surfaces with the two tablespoons of oil in total. Season and roast, first checking at 25 minutes; continue until the thick flesh is readily pierced. Larger halves can need substantially longer.
03 -
Heat the separate tablespoon of oil in a skillet, wilt the spinach and drain any excess liquid.
04 -
Mix softened cream cheese with spinach, Parmesan, cooked chopped bacon and fresh thyme.
05 -
Scoop some tender squash flesh into the filling, leaving a stable shell about half an inch thick. Fill the halves without precarious mounds; place surplus in a separate suitable dish.
06 -
Return to the oven until the filling is hot throughout, using 165°F as the casserole endpoint, and the surface is lightly colored. Begin checking after about ten minutes and continue as necessary.
