This Baked Broccoli Mac and Cheese is creamy, cheesy, and pure homemade comfort food. Packed with tender broccoli and simple cheese sauce, it’s a family-friendly favorite that works as a hearty main or cozy side.
Preheat oven to 375°F and lightly grease a 9x13 casserole dish with nonstick cooking spray.
In a large pot of salted boiling water, cook pasta one minute less than package directions for al dente.
In a large deep skillet, melt butter over medium-high heat. Then sprinkle in all purpose flour, salt and black pepper to make the roux. Let it cook for about 1 minute or so whisking it a few times.
Slowly and gradually pour in the milk while whisking constantly. Let the sauce come up to a bubble and cook until it coats the back of spoon. This takes about 4-5 minutes.
Once the sauce has thickened, add a handful of shredded cheese at a time and whisk it well until it has melted. Repeat until all the cheese is added and melted. Then remove sauce from heat.
Add the drained cooked pasta and frozen broccoli to the cheese sauce. Stir it together until everything is coated in sauce and evenly combined.
Add the mac and cheese to prepared baking dish and spread it out into and layer.
Bake for 25-30 minutes until bubbly and the top is slightly golden brown.
