Ingredients

For the Brown Rice & Broccoli:

• 1 ½ cups uncooked long-grain brown rice, rinsed
• 3 cups vegetable broth (or water)
• 1 large head of broccoli (about 1 lb), cut into small florets
• 1 tbsp olive oil
• ½ tsp salt
• ¼ tsp black pepper

For the Vegan Cheese Sauce:

• 2 tbsp olive oil
• ¼ cup all-purpose flour
• 2 cups unsweetened plain plant-based milk (almond, soy, or oat work well)
• ½ cup nutritional yeast
• 1 tbsp Dijon mustard
• 1 tsp garlic powder
• ½ tsp onion powder
• ¼ tsp turmeric powder (for color, optional)
• ½ tsp salt, or to taste
• ¼ tsp black pepper, or to taste
• Optional: ½ cup vegan shredded cheddar cheese, for topping

Step-by-Step Instructions

1. Cook the Brown Rice: In a medium saucepan, combine the rinsed brown rice and vegetable broth. Bring to a boil, then reduce heat to low, cover, and simmer for 40-45 minutes, or until all liquid is absorbed and rice is tender. Fluff with a fork and set aside. (Alternatively, use 3 cups of pre-cooked brown rice to save time.)
2. Prepare the Broccoli: While the rice cooks, preheat your oven to 375°F (190°C). Toss the broccoli florets with 1 tbsp olive oil, ½ tsp salt, and ¼ tsp black pepper on a baking sheet. Roast for 10-12 minutes, or until tender-crisp and slightly bright green.
3. Make the Vegan Cheese Sauce: In a large saucepan or Dutch oven, heat 2 tbsp olive oil over medium heat. Whisk in the flour and cook for 1-2 minutes, stirring constantly, to create a roux.
4. Whisk in Liquids: Gradually whisk in the plant-based milk, a little at a time, ensuring no lumps form. Continue whisking until the sauce begins to thicken, about 3-5 minutes.
5. Season the Sauce: Remove the saucepan from the heat. Stir in the nutritional yeast, Dijon mustard, garlic powder, onion powder, turmeric (if using), ½ tsp salt, and ¼ tsp black pepper. Taste and adjust seasonings as needed. The sauce should be thick and creamy.
6. Combine Ingredients: Add the cooked brown rice and roasted broccoli florets to the cheese sauce in the large saucepan. Stir gently until everything is evenly coated.
7. Assemble and Bake: Transfer the mixture to a 9×13 inch baking dish. If desired, sprinkle the optional vegan shredded cheddar cheese evenly over the top.
8. Bake to Perfection: Bake for 20-25 minutes, or until the casserole is heated through, bubbly around the edges, and the top is lightly golden.
9. Serve: Let the casserole rest for 5-10 minutes before serving to allow it to set slightly. Enjoy warm!

Pro Tips for Success

• Perfectly Cooked Rice: For the best texture, ensure your brown rice is cooked al dente before adding it to the casserole. Overcooked rice can become mushy when baked further. If using pre-cooked rice, ensure it’s not too wet.
• Don’t Overcook Broccoli: Roasting the broccoli until just tender-crisp prevents it from becoming soggy in the casserole. It will continue to cook slightly in the oven, so aim for a vibrant green and a slight bite.
• Smooth Cheese Sauce: When making the roux, cook the flour for a full minute to remove the raw flour taste. When adding milk, pour it in slowly while continuously whisking to prevent lumps. If lumps do form, a quick blend with an immersion blender can smooth it out.
• Flavor Boost: For an extra layer of flavor, consider adding a pinch of smoked paprika to the cheese sauce. A squeeze of lemon juice at the end can also brighten the flavors.

Variations & Substitutions

• Gluten-Free Option: This recipe is naturally gluten-free if you use a gluten-free all-purpose flour blend for the cheese sauce. Ensure your vegetable broth is also certified gluten-free.
• Other Vegetables: Feel free to swap or add other vegetables. Diced carrots, peas, corn, or sautéed mushrooms would all be delicious additions. Add them to the casserole with the broccoli.
• Spice It Up: For a kick, add a pinch of cayenne pepper or a dash of hot sauce to the cheese sauce. You could also sprinkle red pepper flakes over the top before baking.
• Different Grains: While brown rice offers a hearty texture, you can experiment with other cooked grains like quinoa, farro, or even wild rice for a different flavor profile. Adjust cooking times accordingly.
• Higher Protein: Boost the protein by stirring in a can of drained and rinsed cannellini beans or chickpeas along with the rice and broccoli. You could also add crumbled baked tofu or tempeh.

Serving Suggestions

This Cheesy Baked Broccoli and Brown Rice Casserole is a complete meal on its own, offering a balanced combination of carbohydrates, protein, and vegetables. However, it pairs wonderfully with a simple side salad dressed with a light vinaigrette to add freshness and crunch. A side of crusty bread or garlic knots would also be excellent for scooping up any extra cheesy sauce. It’s perfect for a comforting family dinner, a potluck contribution, or a satisfying weeknight meal.

Storage & Reheating

• Fridge: Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days.
• Freezer: This casserole freezes beautifully! Allow it to cool completely, then transfer individual portions or the entire casserole (if using a freezer-safe dish) to airtight, freezer-safe containers. It will keep in the freezer for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
• Reheating: To reheat, cover the casserole with foil and bake at 350°F (175°C) for 20-30 minutes, or until heated through. For individual portions, microwave until warm, adding a splash of plant milk if it seems dry.

Frequently Asked Questions

Can I use white rice instead of brown rice?

Yes, you can! White rice cooks faster, so adjust your cooking time accordingly. You’ll need about 1.5 cups of uncooked white rice and 3 cups of broth, cooked for about 15-20 minutes. Ensure it’s fully cooked before adding to the casserole.

Can I make this casserole ahead of time?

Absolutely! You can assemble the entire casserole (steps 1-7) and store it covered in the refrigerator for up to 24 hours before baking. Add an extra 10-15 minutes to the baking time if baking from cold.

What if my cheese sauce is too thin or too thick?

If your sauce is too thin, return it to the heat and simmer gently, whisking constantly, until it thickens to your desired consistency. If it’s too thick, whisk in a tablespoon or two of extra plant milk until it reaches the right consistency.
