Mac and Cheese Pizza

Tried my hand at mac 'n cheese pizza for the first time last week. It came out ok but I would definitely use less onion (and Bob said less garlic) next time, Also less mozarella and more cheddar. Here's what I did.

• Saute 1/2 medium onion (maybe 1/4 next time) and 1 1/2 teaspoon garlic (cut to 1?) in a little olive oil. Then remove from pan and set aside. {To be honest I follow a couple different recipes I read online, I thought this step would add depth of flavor much more than it did. I might just try cutting it next time.}
• Melt 4 tablespoons butter and whisk in 3 tablespoon flour. Then whisk in approx. 1 cup milk and cook until thickened.
• Add in onion, garlic and aprrox. 2 1/2 cups cheese (I used half mozzarella and half sharp cheddar, but need to play with different combinations more). Stir until melted and even combined.
• Add to 2 cups cooked macaroni and spread over pizza crust. (I didn't use all of it.) Top with additional cheese and bake at 400 until golden brown.

As I said this was a first effort. I'll report on tweaks when I try it again.
