Step 1: Cook the Pasta

1. In a large pot, bring 4 cups of water to a boil and add 1 tablespoon of salt.
2. Add the macaroni and cook according to the package instructions until al dente, about 8-10 minutes.
3. Drain the pasta and set aside.

Step 2: Make the Cheese Sauce

1. In a separate saucepan, melt 2 tablespoons of butter over medium heat.
2. Once melted, whisk in 2 tablespoons of flour and cook for about 1-2 minutes to create a roux.
3. Gradually add the milk, whisking constantly to prevent lumps. Continue to cook until the mixture thickens, about 5 minutes.
4. Lower the heat and stir in the mozzarella cheese, Parmesan cheese, garlic powder, onion powder, salt, pepper, and Dijon mustard (if using). Stir until the cheese is fully melted and the sauce is smooth and creamy.

Step 3: Combine Pasta and Cheese Sauce

1. Add the drained pasta to the cheese sauce and stir until the macaroni is evenly coated with the sauce.
2. Taste and adjust seasoning if needed, adding more salt or pepper as desired.

Step 4: Serve or Bake

• For Creamy Stovetop Mac and Cheese: Serve immediately while the cheese sauce is creamy and smooth.
• For Baked Mac and Cheese: Transfer the cheesy pasta mixture to a greased baking dish. Sprinkle breadcrumbs over the top for added crunch, and bake at 350°F (175°C) for 15-20 minutes, or until the top is golden brown.
