I love making baked mac and cheese.
It's practically what we live off of in my house since we can't be bothered to keep up with fresh meat.
I use an assortment of noodles. Bowties and the wheels are my favorites.
Mine: Basic roux (3 tbsp butter, 3 tbsp flour). Heat that on the stove top until it combines. If you have non stick, it should naturally pull away from it. Add one cup whole milk. Stir until you've got a white sauce. depending on how hot your stove is, you may need to add more once combined. You want a sauce consistency. Then about a teaspoon of salt and a teaspoon of paprika. Add pepper to taste. Stir in 1 1/2 cups of shredded extra sharp cheddar cheese. Mix it with the noodles, put it in a deep casserole dish, sprinkle 1/2 cup of the cheddar plus 1/4 cup of shredded parmesan on top. Dash with more paprika. Bake for about 45 minutes at about 320-340 F.
Ugh, so good. And it makes an awesome grilled macaroni and cheese the day after.
