Scale
Main Ingredients:
- 4 cups broccoli florets
- 1 cup shredded sharp cheddar cheese
- 1 (10.5 oz) can condensed French onion soup
Supporting Ingredients:
- ½ cup sour cream
- 1 ½ cups crispy fried onions
Seasoning Ingredients:
- 1 tablespoon all-purpose flour
- ¼ teaspoon garlic powder
- ¼ teaspoon black pepper
- ½ teaspoon dried thyme
- Pinch of salt
Instructions
- Warm your oven to precisely 350°F (175°C) and thoroughly coat a 9×13-inch baking dish with cooking spray or butter.
- Steam 4 cups of broccoli florets for 3-4 minutes until bright green and tender, then drain completely.
- Whisk 1 can (10.5 oz) condensed French onion soup with ½ cup sour cream in a large mixing bowl until smooth.
- Sprinkle ¼ teaspoon garlic powder, ¼ teaspoon black pepper, and a small pinch of salt into the soup mixture.
- Fold 1 cup shredded sharp cheddar cheese and 1 cup crispy fried onions into the creamy base until evenly distributed.
- Gently incorporate the steamed broccoli florets into the mixture, ensuring each piece gets coated.
- Transfer the entire mixture to your prepared baking dish, spreading it evenly with a spatula.
- Slide the casserole into the preheated oven and bake uncovered for exactly 20 minutes.
- Scatter the remaining ½ cup crispy fried onions across the top of the casserole.
- Return to the oven for an additional 5-7 minutes until the onions turn golden brown and the edges bubble.
- Remove from the oven and let the casserole rest for 5 minutes before serving to allow flavors to settle.
Notes
- Steam broccoli just until bright green and crisp-tender to prevent mushiness in the final casserole.
- Drain excess liquid from broccoli completely to keep the casserole from becoming watery and losing its creamy texture.
- Use sharp cheddar cheese for maximum flavor depth, which helps enhance the French onion soup’s rich profile.
- For a gluten-free version, swap regular flour with cornstarch or use a gluten-free all-purpose flour blend to maintain the casserole’s thickness.
