This creamy baked macaroni dish is a comforting classic with a crispy topping for added texture.
Cook the macaroni in a large pot of salted boiling water until just underdone, then drain.
Undercooking the pasta ensures it doesn't become mushy during baking.
In a double boiler, melt the butter and whisk in the flour, ground mustard, salt, and pepper until smooth.
Whisk continuously to prevent lumps from forming.
Gradually add the milk to the roux, stirring constantly until the mixture thickens and becomes creamy.
Adding the milk slowly helps achieve a smooth sauce.
Stir in the grated cheddar cheese until fully melted and the sauce is smooth.
Use freshly grated cheese for the best melting consistency.
Combine the cooked macaroni and finely chopped onion in a casserole dish, then pour the cheese sauce over and mix well.
Ensure the macaroni is evenly coated with the sauce.
Mix the bread crumbs with melted butter and sprinkle over the macaroni mixture.
Panko bread crumbs provide a crispier texture.
Bake the casserole uncovered in a preheated oven at 400°F for 20 minutes until golden and bubbly.
Place the dish on a baking sheet to catch any drips.
Let the casserole cool slightly before serving. Enjoy your creamy baked macaroni with crispy topping!
Allowing the dish to rest helps it set and makes serving easier.
