Ingredients

Scale

Main Ingredients

  • 1 lb broccoli florets, chopped
  • 1 (10.5-oz) can unsalted cream of mushroom soup
  • 1 cup refrigerated sour cream-based French onion dip
  • 1½ cups shredded cheddar cheese
  • 1 (6-oz) container French fried onions

Instructions

  1. Preheat oven and prepare dish: Preheat your oven to 350ºF (175ºC) and lightly spray a 9×9-inch baking dish with cooking spray to prevent sticking and ensure easy cleanup.
  2. Mix the casserole ingredients: In a large bowl, combine the chopped broccoli florets, cream of mushroom soup, French onion dip, 1 cup of shredded cheddar cheese, and half of the French fried onions. Stir everything together until evenly mixed and well coated.
  3. Assemble the casserole: Spread the broccoli mixture evenly into the prepared baking dish, spreading it out to create an even layer for consistent cooking.
  4. Bake the casserole: Bake in the preheated oven for 25 minutes, allowing the flavors to meld and the broccoli to soften slightly.
  5. Add toppings and finish baking: Remove the casserole from the oven and sprinkle the remaining ½ cup of shredded cheddar cheese and the rest of the French fried onions over the top. Return to the oven and bake for an additional 5 minutes, or until the cheese is melted and bubbly and the onions are golden and crispy.

Notes

  • For a lower sodium version, opt for low-sodium cream of mushroom soup and reduced-sodium French fried onions.

  • This casserole is best enjoyed warm and can be reheated in the oven or microwave.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
