Heat oven to 375 - 400 degrees (F)
Cut acorn squash in half & scoop the seeds out (I use a spoon or my hand)
Add 1 tbsp of butter, 1 tsp of maple syrup, 1 tbsp of brown sugar, salt and pepper in the hole of each scooped out half
Spray Pyrex baking dish with cooking spray (one that can fit both halves of the squash without touching – you can use really any baking dish)
Place upright in baking dish
Roast for 1 hour (you should be able to pierce the skin with a sharp knife)
Once cooked sprinkle with just a pinch of rosemary or thyme (these are strong spices so it is just to make it look pretty not for flavor)
