If you are using blocks of cheese shred them and put them to the side.
In a large pot bring the water, vegetable oil, and sea salt to a boil.
In another pot add your milk, evaporated milk, butter, adobo, seasoned salt, onion powder, garlic powder, paprika, and black pepper. Heat over medium heat until the butter is melted and the milk is hot (stir frequently to avoid burning)
Once the pot of water is boiling pour the elbow macaroni in the pot and give a quick stir. Cook according to the instructions of the back for al dente. *You don’t want the pasta to be mushy*
Drain the finished pasta and pour in the baking dish.
Now add one handful of each of the three cheeses, and half of the hot milk and butter mixture to the elbow macaroni in the baking dish and stir to allow the cheese to melt.
Pour the last half of the hot milk and butter mixture in the baking dish, add another handful of cheddar cheese, and the remaining asiago and romano cheeses. *Leave about 1.5-2 cups of mild cheddar cheese on the side (this will be the topping)
Now is the time to taste test the macaroni. If you want to add more seasoning do so now. (I recommend adding small doses of adobo or seasoned salt and black pepper to start if necessary)
Bake for 15 minutes covered with foil and bake for another 10-15 minutes uncovered or until the top starts to crust.
Let it rest for 5-10 minutes and now it’s time to dig in!
