A cozy and creamy pumpkin butter overnight French toast casserole perfect for fall breakfasts. This easy make-ahead dish combines the richness of pumpkin butter with warm spices and custardy bread for a comforting seasonal treat.
Use brioche or challah bread for best texture. For dairy-free, substitute milk with oat, almond, or coconut milk and butter with coconut oil. Avoid over-soaking bread more than 24 hours to prevent sogginess. Tent with foil if top browns too fast. Pumpkin butter adds richness and spice that pumpkin puree lacks. Leftovers keep well refrigerated for 3 days or frozen for up to 2 months.
