Here is a recipe I adapted from one I got from Martha Stewart for Mac and Cheese. Very yummy and way better than the kind from a box.
To make this Easy Mac and Cheese you will need:
2/3 stick REAL butter
1/3 cup finely chopped onion
1/3 cup flour
3 cups whole milk
1 cup heavy whipping cream
1 pound cheddar (I prefer extra sharp or white)
1 pound elbow macaroni
water to cook macaroni with
salt to taste
Start by melting your butter in a large pot.
Then add your chopped onions.
When your onions are soft and translucent, add the flour.
The flour is what helps thicken the sauce.
Stir this on a low flame for about 2-3 min.
Now it is time to add the milk and cream.
Whisk thoroughly to get rid of any flour lumps.
Add your salt and choice of seasonings
(I sometimes add some garlic powder or use garlic salt)
Do not use too much salt because there is plenty in the cheese and you don't want to over do it!
At this point do two things: shred your cheese if it is not ready now...
...and cook your macaroni according to the instructions on the package.
Between everything you are doing whisk your sauce often. If you don't you will end up with lumps. The sauce will thicken as it boils. When the sauce coats the back of a spoon its ready. This is knows as "nape."
At this point, congrats you have made a "roux." Turn off the flame.
When your macaroni is ready drain it and put it to the side for now.
Shake well to remove any excess water.
In three parts gradually add your shredded cheese. Whisk after every addition.
Season if needed and add your cooked macaroni.
Stir it and you are done!
