TIPS FOR MAKING CHEESY GARLIC BROCCOLI CASSEROLE

  • Prep: To start the recipe off, preheat your oven and spray the casserole dish with cooking spray. If you don’t have a nonstick spray, brush melted butter over the dish. The key is to have some kind of coating so the broccoli doesn’t bake and get stuck to the dish. You should also chop your broccoli into florets if it’s not already in small enough pieces.
  • Sauce: Add 4 tablespoons of butter to your saucepan and turn the heat on to melt it. As soon as the butter melts, stir in the flour, salt, and pepper. Mix the ingredients together and cook until it’s bubbly and the flour isn’t raw. It should only take about 1 minute. Pour the milk in slowly and whisk as you go until the mixture is smooth. Cook and stir the milk until it’s thick and bubbly. Then you can mix in the garlic, cheddar cheese, and parmesan. Continue stirring until the cheese melts into the sauce. Add in the broccoli pieces and mix until the sauce coats all the florets. Transfer broccoli and sauce to the casserole dish. Use your mixing spoon to spread it out evenly across the dish.
  • Breadcrumbs: Put another saucepan over medium-high heat. Add the remaining butter and the bread crumbs. Stir until the melted butter coats the lightly toasted breadcrumbs. 
  • Bake: Sprinkle the breadcrumbs evenly over the casserole and bake for 30 minutes. You want the cheese sauce to be nice and bubbly before you take it out of the oven.

VARIATIONS ON CHEESY GARLIC BROCCOLI CASSEROLE

  • Main dish: To make this casserole into a more filling main dish recipe, try adding some cooked rice or cooked quinoa. You can also add protein with cooked chicken. If you have any leftover baked chicken, just cut it into pieces to mix in with the broccoli. 
  • Add-ins: For some more add-ins try chopping up onion, zucchini, or cauliflower to cook along with the broccoli. You can also add slivered almonds in with the breadcrumb topping for some extra flavor and crunch. 
  • Breadcrumbs: Instead of panko bread crumbs, you can break any regular kind of bread into pieces and leave it out overnight to dry out. You can also crumble crackers over the top of your casserole in place of breadcrumbs. 
  • Seasoning: For extra flavor try adding oregano, basil, Italian seasoning, cayenne pepper, or onion powder. 
  • Cheese: There’s nothing wrong with a little extra cheese! Swiss, gouda, Pepper Jack, Munster, provolone, or Mozzarella Cheese would all make lovely additions to the casserole.
