Introduction

This Vegan Potato Broccoli Casserole is a comforting and creamy dish perfect for family dinners or meal prep. It combines tender potatoes and broccoli with a rich dairy-free sauce, topped with melted vegan cheese for a deliciously satisfying meal.

A wooden spoon is scooping out a portion from the top left corner, showing gooey and creamy textures beneath the top crust. Around the dish on a white marbled surface, there are crispy toasted bread slices, two whole heads of garlic, small wooden bowls with coarse salt and peppercorns, and green herb sprigs adding fresh green highlights.

Ingredients

2.2 lbs potatoes
17.6 oz broccoli

1 cup dairy-free cooking cream
1 tsp dried rosemary

1 tsp dried oregano
1 tsp dried thyme

2 tsp paprika powder
1 clove garlic, pressed
Salt and pepper to taste

3.5 oz vegan butter or margarine
3 tbsp flour
1 cup vegetable broth

6 tbsp nutritional yeast flakes
1 cup vegan grated cheese (optional)

Instructions

Step 1: Preheat your oven to 356 ºF (180 ºC).

Step 2: Peel the potatoes and chop them into bite-sized cubes. Wash the broccoli, separate the florets, and chop them into small pieces.
Step 3: In a large pot, combine the dairy-free cooking cream with rosemary, oregano, thyme, paprika powder, pressed garlic, and a pinch of salt and pepper. Bring this mixture to a boil.
Step 4: Add the potatoes and broccoli to the pot, mix well, cover with a lid, and cook for 2 minutes. Then transfer the mixture to a baking dish.

Step 5: Melt the vegan butter in a saucepan over medium heat. Whisk in the flour and sauté for a few seconds until lightly golden.
Step 6: Pour in the vegetable broth and stir in the nutritional yeast flakes. Bring the sauce to a boil, then simmer for about 2 minutes until it thickens slightly. Season with salt and pepper to taste.
Step 7: Pour the sauce evenly over the potatoes and broccoli in the baking dish and toss to coat everything well.

Step 8: Bake the casserole for 30 minutes. If desired, sprinkle vegan grated cheese on top and bake for another 15 minutes until the cheese melts and the potatoes are tender.
Step 9: Remove from oven and let it cool slightly before serving. Enjoy your comforting casserole!

Tips & Variations

For a nuttier flavor, try adding some toasted breadcrumbs or chopped nuts as a topping before baking.

You can substitute the broccoli with cauliflower or a mix of your favorite vegetables.
If you prefer a spicier dish, add a pinch of chili flakes to the sauce.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm the casserole in the oven at 350 ºF (175 ºC) until heated through, about 15-20 minutes. Avoid microwaving to keep the texture creamy and prevent sogginess.

FAQs

Can I use fresh herbs instead of dried?

Yes, you can substitute dried herbs with fresh ones, but use about three times the amount since fresh herbs are less concentrated in flavor.

Is this casserole suitable for gluten-free diets?

To make this casserole gluten-free, use a gluten-free flour blend instead of regular flour and ensure your vegetable broth and vegan cheese are gluten-free as well.
