Homemade Mac and Cheese

I am always changing and adding to this recipe but here is the basic recipe that I use...Most of the time ;)

Ingredients:
- 1 box Elbow Noodles
- 2 cups Milk
- 1/4 cup stick butter (1/2 stick)
- 1 chopped onion
- 1 tsp. garlic powder or freshly minced garlic
- Salt and Pepper to taste
- 1/4 Cup Flour 
- 1/4 cup Velvetta Cheese (cubed)
- 1/2 cup Mild Cheddar (shredded)
- 1/2 cup Colby-Jack (shredded)
- 1/4 cup Swiss (shredded)
- Panko Bread crumbs

Directions:
- Cook elbow noodles according to the directions, set aside
- Melt butter, saute onions and garlic in saucepan.
- Add milk and bring to a boil.
- Whisk in flour slowly into the milk mixture. Whisking will create a nice rue (think milk base) to add your cheese.
- Once a creamy, thick consistency add cheeses. Slowly mix them into milk mixture and allow the cheese to melt.
- In a bowl mix noodles and sauce together.
- Transfer to a baking dish of your choosing and top with bread crumbs and extra cheese
- Bake at 350 degrees for 25-30 minutes. Enjoy!
