Made completely from scratch, this Broccoli Cheese Rice Casserole leaves out the processed cheese and condensed soup to deliver a casserole that is delicious enough for the holidays yet easy enough for weeknight dinners!
Preheat oven to 350℉/175℃. Grease a 2-quart casserole dish with butter or spray with nonstick spray.
In a large saucepan, melt 2 tablespoons unsalted butter over medium-low heat on the stove. Once the butter is melted, whisk 2 tablespoons all purpose flour and cook for 1-2 minutes, whisking constantly.
Slowly whisk in 1 cup low-sodium chicken stock or vegetable broth, allowing the liquid to fully combine into the flour mixture. Once combined, whisk in 1 cup milk and season with 1 teaspoon onion powder, ½ teaspoon garlic powder, ½ teaspoon kosher salt, and ¼ teaspoon black pepper. Continue cooking over medium heat until thick and bubbly, whisking constantly. ~2-3 minutes.
Once the sauce is thick enough to coat the back of the spoon, remove it from the heat. Add in 1 cup shredded cheddar cheese and stir to melt. Add in 1 cup shredded cheddar cheese and 4 cups lightly steamed broccoli and and stir to combine.
Pour the broccoli rice mixture into the greased casserole dish and top with remaining 1 cup shredded cheddar cheese and ¼ cup grated parmesan cheese.
Bake, uncovered, for 30-35 minutes, or until lightly browned and warmed through.
