Creating the Easy Macaroni and Cheese is a straightforward process. Follow these steps for a delicious result:

1. Cook the Macaroni: In a large pot, bring salted water to a boil. Add the elbow macaroni and cook according to package instructions until al dente. Drain and set aside.
2. Make the Roux: In a medium saucepan, melt the butter over medium heat. Once melted, whisk in the flour and cook for about 1 minute until bubbly.
3. Add the Milk: Gradually whisk in the milk, stirring continuously to avoid lumps. Bring the mixture to a simmer and cook until it thickens, about 3-5 minutes.
4. Incorporate the Cheese: Remove the saucepan from heat. Stir in the shredded cheddar and mozzarella cheese until melted and smooth. Add the salt, pepper, garlic powder, and onion powder, if using. Mix well.
5. Combine Pasta and Sauce: Add the cooked macaroni to the cheese sauce. Stir until the pasta is well coated.
6. Add Parmesan (Optional): For an extra cheesy finish, sprinkle grated Parmesan cheese over the macaroni and cheese, mixing it in.
7. Serve Immediately: This dish is best enjoyed fresh and hot. Serve it up in bowls or on plates.
