This Old Fashioned Baked Mac and Cheese is the cozy, cheesy comfort food your whole family will devour! Made from scratch with real cheese and no shortcuts, but easy to make.
Preheat oven to 350°F. Butter a 9x13-inch baking dish, or lightly spray with cooking spray.
Cook macaroni in salted water according to package directions until al dente (about 2 minutes less than fully cooked). Drain and set aside. 1 pound elbow macaroni.
In a large saucepan or Dutch oven, melt butter over medium heat. Add flour and whisk constantly for 2 minutes to make a roux. 1/2 cup butter,1/2 cup all-purpose flour.
Gradually whisk in warmed milk, a little at a time, stirring constantly to prevent lumps. Cook the sauce, stirring frequently, until it thickens and can coat the back of a spoon, about 5–7 minutes. 4 1/4 cups whole milk.
Remove from heat and stir in dry mustard, onion powder, salt, and pepper. 1 teaspoon dry mustard powder,1/2 teaspoon onion powder,3/4 teaspoon salt,1/4 teaspoon black pepper.
Add 2 cups of the cheddar cheese, all of the Colby-Jack, American cheese, and Parmesan. Stir until completely melted and smooth. 3 1/2 cups sharp cheddar cheese,1 cup Colby-Jack cheese,10 slices American cheese,1/4 cup Parmesan cheese.
Fold in the cooked macaroni until well coated with cheese sauce.
Pour the mixture into the prepared baking dish and spread evenly. Sprinkle the remaining 1 1/2 cups of cheddar cheese over the top.
Bake uncovered for 20–25 minutes, or until bubbly and lightly golden on top. Let stand for 10 minutes before serving.
Notes
Pro Tip:
For best results, shred your own cheese instead of using pre-shredded cheese. It melts smoother and gives the creamy sauce a richer texture.
