  • 1 medium onion, diced
  • 3 cloves garlic, minced
  • 1 red bell pepper, diced
  • 1 medium zucchini, diced
  • 1 cup broccoli florets
  • 1 cup sliced mushrooms
  • 1 cup frozen corn kernels
  • 1 cup shredded vegan cheese (optional)
  • 1 cup plant-based milk (unsweetened)
  • 2 tablespoons all-purpose flour or gluten-free flour
  • 1 teaspoon dried thyme
  • 1 teaspoon smoked paprika
  • Salt and black pepper to taste
  • Fresh parsley or basil for garnish (optional)

Equipment

  • Large saucepan or pot (for cooking rice)
  • Large skillet or frying pan
  • Mixing bowl
  • Whisk (for sauce)
  • 9×13 inch casserole dish
  • Measuring cups and spoons
  • Spatula or wooden spoon

Instructions

  1. Cook the rice: In a saucepan, bring 2 cups vegetable broth to a boil. Add 1 cup rice, cover, and reduce heat to low. Simmer for 15-20 minutes until rice is tender and liquid is absorbed. Set aside.
  2. Prepare the veggies: While the rice cooks, heat 1 tablespoon olive oil in a large skillet over medium heat. Add diced onion and sauté for 3-4 minutes until translucent.
  3. Add garlic and vegetables: Stir in minced garlic, diced red bell pepper, zucchini, broccoli florets, mushrooms, and corn. Cook, stirring occasionally, for 6-8 minutes until vegetables are tender but still vibrant.
  4. Make the creamy sauce: In a small bowl, whisk together 2 tablespoons flour and 1 cup plant-based milk until smooth. Pour this mixture into the skillet with veggies, stirring constantly. Add thyme, smoked paprika, salt, and pepper. Cook for 3-4 minutes until sauce thickens.
  5. Combine rice and veggies: Gently fold the cooked rice into the skillet mixture until everything is well coated with the sauce.
  6. Transfer to casserole dish: Pour the rice and veggie mixture into a greased 9×13 inch casserole dish. Spread evenly.
  7. Add cheese (optional): Sprinkle shredded vegan cheese evenly over the top for a melty, golden crust.
  8. Bake: Preheat your oven to 375°F (190°C). Bake the casserole uncovered for 20-25 minutes until the top is golden and bubbly.
  9. Garnish and serve: Remove from oven and let cool for 5 minutes. Garnish with fresh parsley or basil if desired. Serve warm.

Tips & Variations

“Feel free to swap veggies based on what’s fresh or in your fridge — carrots, peas, green beans, or spinach make excellent additions.”

  • Use brown rice: For a nuttier flavor and extra fiber, substitute brown rice. Increase cooking time slightly.
  • Gluten-free option: Use gluten-free flour or cornstarch to thicken the sauce.
  • Make it spicy: Add a pinch of cayenne pepper or a dash of your favorite chili powder for extra heat. Check out this Chilli Powder Recipe Vegan: Easy Homemade Spice Blend for inspiration.
