Macaroni and Cheese the whole family can agree on. Six ingredients come together to make the best version you've ever tasted! Inspired by Macaroni au Gratin of Poole's Diner fame.
In a medium sized sauce pot, bring water to a boil. Add elbow macaroni with several pinches of salt and cook according to package directions until al dente. Drain and set aside.
While pasta is cooking, add heavy cream and salt to a small sauce pot and bring to a boil over high heat. Reduce heat to medium-low, and simmer until reduced by 25%, about 7 to 10 minutes. Final measurements should be 1 ⅛ Cup/9 oz., or 270ml, (Keep an eye on the pot so it doesn't boil over, and stir consistently to avoid scorching).
While pasta is cooking and cream is simmering, shred all three cheeses into a bowl and mix to combine. Divide the cheese mixture into two bowls, approximately 40% in one and 60% in the other.
Preheat broiler on high. Set grate approx. 4-inches from the burner.
Once cream is reduced, remove from the heat and slowly add 60% of the cheese mixture a handful at a time. Stir each addition until melted and smooth. Add the pasta and stir to coat evenly.
Add the pasta and cheese mixture to a 7 x 11-inch casserole dish. Cover with the remaining 40% of the cheese mixture.
Broil for 3 to 5 minutes until cheese is melty and bubbly. Serve warm and garnish with minced parsley and a pinch of flakey salt if desired.
