FAQs
Can I prepare this dish ahead of time?
Yes, you can assemble the casserole and keep it covered in the refrigerator for up to 24 hours before baking. Baking time may need slight adjustment if the casserole is cold from the fridge.
How do I cook the spaghetti squash?
You can roast the spaghetti squash in the oven at 400°F (200°C) for about 40 minutes, or microwave it until tender. Once cooked, let it cool, then scrape out the flesh with a fork to create the “spaghetti” strands.
