How to make Leftover Broccoli Casserole

To prepare the broccoli casserole, start by preheating the oven to 375°F (190°C). This ensures even baking. If the leftover broccoli is too large, chop it into smaller pieces.

In a large mixing bowl, combine dairy-free mushroom soup and non-dairy sour cream to create a creamy base. Add garlic powder, cayenne pepper, onion powder, and a pinch of salt to the mixture, and stir well to evenly distribute the spices. Then, add the chopped broccoli and vegan bacon bites to the bowl, gently stirring to coat the broccoli evenly.

Transfer the mixture to a greased baking dish, spreading it out evenly and topping it with shredded vegan cheddar cheese. Place the casserole in the preheated oven and bake for 25-30 minutes, until the top is golden and bubbly. Once baked, remove the casserole and let it cool for a few minutes before serving. This delicious casserole makes a perfect standalone dish or a complement to your favorite main course.

Tips and Variations for this Leftover Broccoli Casserole

  • Add Crunch: Top the casserole with crushed vegan crackers or breadcrumbs before baking for an extra crunchy layer.
  • Extra Veggies: Feel free to add other leftover vegetables like carrots, peas, or cauliflower to the mix.
  • Spice Level: Adjust the cayenne pepper according to your spice preference. A little more can add an extra kick, while less will keep it milder.
