Ingredients
Broccoli Casserole Ingredients
- 1 (10.5-ounce) can cream of mushroom soup
- 1 cup mayonnaise
- 1 tablespoon Dijon mustard
- ½ small yellow onion, grated
- 2 teaspoons onion powder
- 2 large eggs, beaten
- 6 cups broccoli florets (from 2 large crowns)
- 1½ cups grated sharp cheddar cheese
- 1 cup panko breadcrumbs
- 1 tablespoon extra-virgin olive oil
Instructions
- Preheat the oven: Set your oven to 375°F and arrange the oven rack in the center position to ensure even baking.
- Prepare the creamy mixture: In a large mixing bowl, combine the cream of mushroom soup, mayonnaise, Dijon mustard, grated yellow onion, onion powder, and beaten eggs. Mix thoroughly to blend all the flavors.
- Combine broccoli and mixture: Add the broccoli florets and 1 cup of grated sharp cheddar cheese to the baking dish, then pour in the prepared creamy mixture. Stir gently within the dish to distribute ingredients evenly.
- Prepare topping: In a small bowl, mix the panko breadcrumbs with the extra-virgin olive oil to coat the crumbs. Sprinkle the remaining ½ cup of cheddar cheese evenly over the broccoli mixture, then top with the oiled panko breadcrumbs for a crunchy finish.
- Bake covered: Cover the casserole dish with foil and bake in the preheated oven for 15 minutes to allow the ingredients to meld and broccoli to soften slightly.
- Bake uncovered: Remove the foil and continue baking for approximately 30 more minutes, or until the casserole is golden brown on top and bubbling around the edges.
- Rest and serve: Remove the casserole from the oven and let it rest for a few minutes before serving to allow it to set and cool slightly for best texture and flavor.
Notes
- Make sure to grate the yellow onion finely to blend well without large chunks.
- Using fresh broccoli crowns ensures tender florets that bake evenly.
- You can substitute cream of mushroom soup with cream of chicken soup for a different flavor profile.
- For extra crispiness, toast the panko lightly in a skillet before adding olive oil and topping the casserole.
- This casserole can be prepared a few hours ahead and baked before serving.
- Leftovers keep well and can be reheated in the oven or microwave.
