# Expert tips:

01 -
  • Everything cooks in one skillet before baking, so you have minimal cleanup while still getting those perfect caramelized flavors
  • The combination of sweet roasted squash and savory Italian sausage creates this incredible sweet and salty balance that keeps everyone coming back for seconds
02 -
  • Cutting butternut squash can be tricky and dangerous if your knife is not sharp. A sharp knife is actually safer because it requires less force and is less likely to slip.
  • The casserole needs those 5 minutes of resting time, or it will be too loose and runny when you try to serve it. I learned this the hard way when I served it immediately and ended up with a delicious mess on plates.
03 -
  • Buy pre-cut butternut squash from the store to save time and effort. It costs a bit more but absolutely worth it on busy weeknights.
  • Grate your own cheese from blocks instead of buying pre-shredded. The difference in melting quality and flavor is noticeable.
