Common Mistakes to Avoid

Using too much liquid: Excess broth or plant milk can make the rice soggy; measure liquids carefully and remember that cooked rice requires less additional moisture than uncooked rice.
Overcooking the broccoli before baking: Very soft broccoli may become mushy in the oven; blanch it briefly or add it raw in small florets.
Using rice that is too wet: If the rice has just been cooked and is excessively moist, the casserole may become sticky; drain or fluff it well before mixing.
Baking uncovered for too long: The surface can dry out before the center is hot; cover loosely with foil if the cheese begins browning too quickly.

Required Equipment

Large baking dish: Holds the rice, vegetables, and sauce evenly for consistent baking.
Medium saucepan: Helps prepare the creamy sauce without scorching it.
Large mixing bowl: Makes combining the rice, broccoli, mushrooms, and sauce easy.
Sharp chef’s knife: Cuts the broccoli, mushrooms, and onion into even pieces.
Cutting board: Provides a stable surface for safe preparation.
Measuring cups and spoons: Keep the rice, broth, and seasonings consistent.
Wooden spoon or silicone spatula: Mixes the casserole without crushing the vegetables.
Aluminum foil: Helps prevent the top from overbrowning before the center heats through.

Storage Instructions

Allow the casserole to cool slightly before portioning it into shallow, airtight containers.

Refrigerator: Store leftovers at 40°F (4°C) or below for 3–4 days.

Freezer: Freeze individual portions in freezer-safe containers for up to 2 months for best texture. The rice may soften slightly after thawing, and the vegan cheese sauce may change texture depending on the brand.

Thawing: Defrost overnight in the refrigerator for more even reheating.

Reheating in the oven: Place a portion in an oven-safe dish, add 1–2 tablespoons of vegetable broth or unsweetened plant milk, cover loosely with foil, and heat at 350°F (175°C) for approximately 15–25 minutes, or until hot throughout.

Reheating in the microwave: Place an individual portion in a microwave-safe container, add a small splash of broth or plant milk, cover loosely, and heat in 1-minute intervals, stirring between intervals where possible.

Food safety: Refrigerate cooked rice promptly, ideally within 1 hour when practical, and never leave the casserole at room temperature for more than 2 hours. Reheat only the portion you plan to eat.

📝 Ingredients

Makes 6 servings

For the rice and vegetables

3 cups cooked rice (approximately 450–500 g)
2 cups broccoli florets (approximately 180 g)
8 oz (225 g) cremini or button mushrooms, sliced
1 medium yellow onion, finely chopped
3 cloves garlic, minced
1 tablespoon olive oil
1/2 teaspoon salt, or to taste
1/2 teaspoon ground black pepper
1 teaspoon dried thyme
1/2 teaspoon paprika

For the creamy vegan cheese sauce

1 tablespoon olive oil or vegan butter
2 tablespoons all-purpose flour
1 1/2 cups (360 ml) unsweetened plant milk
1/2 cup (120 ml) vegetable broth
1 tablespoon nutritional yeast
1 teaspoon Dijon mustard
1 cup (100–120 g) shredded vegan cheese, divided
1/4 teaspoon garlic powder, optional

For the topping

2 tablespoons chopped fresh parsley
2 tablespoons extra shredded vegan cheese, optional if not included in the amount above

Ingredient notes:

Use cooked, cooled rice for this recipe. White or brown rice both work.
Fresh or frozen broccoli can be used; thaw and drain frozen broccoli before adding it.
Choose unsweetened plant milk, preferably soy or oat milk for a creamy sauce.
Check that the vegan cheese, mustard, and broth are suitable for a vegan diet.

Directions

Step 1: Preheat the oven

Preheat the oven to 375°F (190°C). Lightly grease a medium-large baking dish with a little olive oil or vegan butter.

Timing: 5 minutes.

Step 2: Prepare the vegetables

Wash and cut the broccoli into small florets. Slice the mushrooms, finely chop the onion, and mince the garlic.

If using fresh broccoli and you prefer a softer texture, blanch it in boiling water for 2 minutes, then drain well. For firmer broccoli, add it directly to the casserole.

Step 3: Sauté the mushrooms

Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the sliced mushrooms and cook for 5–7 minutes, stirring occasionally, until their moisture evaporates and the edges turn golden.

Add the onion and cook for another 3–4 minutes until softened. Stir in the garlic, thyme, paprika, salt, and black pepper, then cook for 30–60 seconds until fragrant.

Visual cue: The mushrooms should look browned rather than watery.

Step 4: Prepare the creamy sauce

In a saucepan, heat 1 tablespoon olive oil or vegan butter over medium heat. Stir in the flour and cook for 1 minute.

Gradually whisk in the plant milk and vegetable broth to prevent lumps. Add the nutritional yeast, Dijon mustard, and garlic powder if using.

Cook for 3–5 minutes, stirring frequently, until the sauce thickens enough to coat the back of a spoon.

Reduce the heat to low and stir in about 3/4 cup of the shredded vegan cheese until melted. Keep the sauce warm but avoid boiling it vigorously.

Step 5: Combine the ingredients

Place the cooked rice, broccoli, sautéed mushrooms, and onion mixture in a large mixing bowl. Pour the creamy sauce over everything and fold gently until evenly coated.

Texture cue: The mixture should be creamy and moist without pooling with excess liquid. Add a small splash of broth if it seems too dry.

Step 6: Assemble the casserole

Transfer the mixture to the prepared baking dish and spread it evenly. Sprinkle the remaining vegan cheese over the top.

Cover loosely with foil if you want to prevent the cheese from browning too quickly.

Step 7: Bake

Bake at 375°F (190°C) for 20 minutes. Remove the foil and bake for another 8–12 minutes, until the edges bubble and the cheese melts with lightly golden spots.

If you are using refrigerated ingredients, allow a few extra minutes as needed. The center should be piping hot, reaching 165°F (74°C) if measured with a food thermometer.

Step 8: Rest and serve

Remove the casserole from the oven and let it rest for 5 minutes. Sprinkle with chopped parsley and serve warm.

Vegan cooking tip: For extra cheesy flavor, sprinkle a little nutritional yeast over the top just before serving. Add chickpeas, white beans, or crumbled tofu before baking if you want more plant-based protein.
