Ingredients
Vegetables
- 1 cup chopped sweet or yellow onion
- 2 cups sliced mushrooms (about 8 ounces)
- 1 pound fresh broccoli, chopped into larger pieces
Sauce & Seasonings
- Drizzle of olive oil (or broth if you don’t use oil)
- 3 cups vegan Alfredo sauce (or cream sauce of choice)
- ½ teaspoon sea salt (for vegetables)
- ¼ teaspoon ground black pepper
Topping
- ½ cup vegan parmesan
- ½ cup breadcrumbs (gluten-free if needed)
- 2 teaspoons garlic powder
- 2 teaspoons dried parsley
- ½ teaspoon sea salt
Instructions
- Preheat Oven: Preheat your oven to 350 degrees F (175 degrees C) to prepare for baking the casserole later.
- Sauté Onions: In a skillet, heat a drizzle of olive oil or broth over medium heat. Add the chopped onions and sauté for about 5 minutes until they become soft and translucent.
- Add Mushrooms and Season: Add the sliced mushrooms along with ½ teaspoon sea salt and ¼ teaspoon ground black pepper to the pan. Continue to sauté for another 1-2 minutes until mushrooms begin to soften.
- Cook Broccoli: Add the chopped broccoli to the skillet and sauté for about 5 minutes to encourage browning. For a softer texture, cover the skillet and cook to steam the broccoli for an additional 2-3 minutes.
- Stir in Sauce: Remove the skillet from heat and stir in the 3 cups of vegan Alfredo sauce until the vegetables are evenly coated.
- Prepare Topping: In a separate bowl, combine vegan parmesan, breadcrumbs, garlic powder, dried parsley, and ½ teaspoon sea salt. Mix thoroughly to create the casserole topping.
- Assemble Casserole: Pour the vegetable and sauce mixture into a square baking dish. Evenly distribute the topping mixture over the surface of the casserole.
- Bake: Bake the casserole in the preheated oven for 15-20 minutes, or until the sauce is bubbling and the topping has turned a light golden brown.
- Serve: Remove from the oven and serve warm as a hearty main or side dish.
Notes
- For a gluten-free option, use gluten-free breadcrumbs.
- You can substitute olive oil with vegetable broth to reduce fat content.
- The broccoli pieces can be chopped larger or smaller depending on preferred texture.
- Feel free to use any vegan cream sauce in place of Alfredo sauce if desired.
