FAQ's
Yes, this casserole is covered with foil while it bakes. This helps to prevent the cheese from browning too much. Just be sure to remove the foil for the last few minutes of baking so that the cheese can get nice and bubbly.
You can assemble this casserole and place it in the fridge for up to 24 hours and then bake it when you are ready to serve.

Deb's tips
Make sure that you boil the noodles to al dente. This will help to prevent them from getting mushy when they are baked in the casserole.
- Soften the cream cheese before trying to mix it with the remaining ingredients. It will creamy and mix well if softened first.
- Half and half is equal parts milk and cream. You can also use all milk or all cream in this recipe. The higher the fat content, the richer the sauce will be.

Variations
- I recommend full-fat cream cheese. It makes the richest sauce.
- Mozzarella cheese is my favorite in this dish, but you could also use cheddar cheese or pepper jack.
- I've started adding bacon to this dish. Eight strips of cooked, bacon crumbled. Oh boy, does that bring the flavor!
- Parmesan cheese is used for both flavor and texture in this dish. If you don’t have it on hand, you could use another hard-grating cheese like Romano.
- A crunchy topping would be terrific as well. Crushed Ritz crackers is super tasty.

I thought 1 tsp of garlic powder made it way too garlicky (and I like garlic). I just thought it ruined the dish.
