Delicious Dinner Ideas: Broccoli Cheddar Casserole

Delicious Dinner Ideas: Broccoli Cheddar Casserole

Recipe By: @athomewithastghik 

I love to pair broccoli with sharp cheddar cheese; they just pair so nicely together! Here I made a cheese sauce and baked it with broccoli. I added some mushrooms and spinach to the casserole to help make it extra nutritious! 

I served it with quinoa, but you may serve it on its own, with rice, or anything else that’s desired. I also pair it with a side of steamed sweet potatoes, diced strawberries, and halved blueberries.


  • 2 tablespoons oil
  • 1/2 large onion, finely diced
  • 2 1/2 pounds of broccoli
  • 4 pieces of Cremini mushrooms, cleaned and finely diced
  • 3 tablespoons unsalted butter
  • 1/4 cup all purpose flour
  • 2 cups whole milk, warmed
  • 1 cup shredded sharp cheddar cheese
  • 1 cup spinach, washed and finely diced
  • 3/4 teaspoon salt, may add more or less
  • 1/4 teaspoon ground pepper
  • 1 cup panko breadcrumbs or may use your favorite breadcrumbs

How to Make Broccoli Casserole: 

  • Preheat oven to 350F
  • Wash the broccoli and cut it into chunks or your preferred size.
  • Bring a pot of water to a boil and add the broccoli. Boil the broccoli for 3 minutes.
  • Transfer to a colander to drain the water. Set it aside.
  • To a pot (I used a 3-quart pot), add the oil and allow it to get hot. Next, add the finely diced onions and mushrooms. Sauté the onions and mushrooms for about 4-5 minutes (stirring occasionally) or until the mushrooms have cooked.
  • Remove from the pot and set it aside with the broccoli.
  • Warm the milk in a saucepan, but don’t bring it to a boil (just enough to warm the milk); This will help prevent the sauce from having any lumps from the flour. Once it has warmed up, turn the heat off and set it aside.
  • To a pot (I used a 3-quart pot), melt the butter and add the flour. Cook it for 3 minutes over medium heat, frequently stirring with a whisk. Next, carefully and slowly add the warm milk while whisking with the other hand. Cook, while constantly mixing with a wooden spoon, until the mixture thickens (about 3 minutes).
Note: you know it has thickened once the mixture coats the back of the spoon.
  • Turn the heat off and add the shredded sharp cheddar cheese. Mix to combine.
  • Add the salt, pepper, and mix. Add the broccoli, spinach, and mushroom mixture.
  • Mix to combine.
  • Transfer to a greased square baking dish.
  • Top with panko bread crumbs, spray the panko breadcrumbs with oil (I used avocado oil-this will help the breadcrumbs to brown).
  • Bake for about 35 minutes or until the sides are bubbling and the top is golden brown.
  • Allow it to cool and serve.
