Looking for the ultimate comfort food? Rich and creamy, this low FODMAP macaroni and cheese will hit the spot!
Preheat your oven to 350 degrees and coat a 9 x 13" baking dish with cooking spray. Then, prepare your pasta according to the package instructions and drain.
In a small bowl, whisk the flour, salt and pepper, and the half and half until it's smooth. Melt the butter in a large saucepan over medium heat. Stir in the mustard until it's dissolved. Then stir in the milk mixture and the regular milk. Bring the mixture to a low boil, stirring constantly.
Once the mixture has reached a boil, remove the pan from the burner and add the cheese, stirring until the cheese has melted. Stir in your pasta and transfer the mixture to your prepared baking dish. If you're using the optional toppings, pop them on now and sprinkle with cheese. Bake uncovered for 25-30 minutes.
Heat up your butter in a large frying pan over medium-high heat. Add your leeks and cook until tender (about 3-5 minutes). Add your bread crumbs and cook for another 2 minutes. Then, sprinkle the bread crumbs over the pasta and top with cheese.
