1Cook the elbow macaroni according to the package instructions. Drain and set aside.
In a large saucepan, melt the butter over medium heat.
Add the flour to the melted butter and whisk continuously for about 1-2 minutes until it forms a smooth paste.
Gradually add the milk to the saucepan, whisking constantly to avoid lumps. Continue to cook and whisk until the mixture thickens, about 3-5 minutes.
Add the shredded cheddar cheese to the saucepan and stir until the cheese is completely melted and the sauce is smooth.
Season the cheese sauce with salt and black pepper.
Add the cooked macaroni and broccoli florets to the cheese sauce. Stir until everything is well combined and the broccoli is heated through.
Serve the Cheesy Mac with Broccoli hot and enjoy!
