Preheat oven to 450 degrees.
Carefully cut squash in half and clean out the seeds and strands. Brush inside flesh with olive oil and season with salt and pepper. Flip flesh side down onto a parchment lined baking sheet and bake roughly 45 minutes to 1 hour. Meanwhile combine;
1/2 cup panko crumbs
1 clove grated garlic
3 Tbs olive oil
1/4 cup finely grated parmesan cheese
Flip squash over and rake the flesh with a fork into strands. Tuck in mozzarella cheese in between the squash. Top with panko crumb mixture. Bake 10 minutes until crumbs are toasted and cheese is melted. Top with parmigiana.
