Ingredients
Scale
- 1 1/2 cups brown rice, cooked
- 2 tablespoons avocado oil
- 1 1/2 pounds cubed zucchini
- 1 cup sliced green onions
- 1 minced garlic clove
- 1 1/4 teaspoons garlic salt
- 1/2 teaspoon dried basil
- 1/2 teaspoon paprika (hungarian or smoked varieties work well)
- 1/2 teaspoon oregano, dried
- 1 1/2 cups chopped tomatoes
- 1 cup or more shredded daiya cheddar style cheese, separated
Instructions
- Preheat and Prepare: Preheat your oven to 375°F (190°C). This temperature is ideal for achieving a bubbly, golden-brown cheese topping without overcooking the tender vegetables. Ensure your cooked brown rice is ready; using day-old rice that's slightly dry helps prevent a mushy final texture.
- Sauté the Aromatics: Heat the avocado oil in a large oven-safe skillet or Dutch oven over medium-high heat. Add the sliced green onions and minced garlic. Sautéing, which means cooking quickly in fat, should take just 1-2 minutes until fragrant. This foundational step builds the flavor base for the entire casserole.
- Cook the Zucchini: Add the cubed zucchini to the skillet. Cook for 5-7 minutes, stirring occasionally, until the zucchini begins to soften and develop light golden edges. Unlike boiling, this dry-heat method caramelizes the natural sugars, enhancing the vegetable's savory quality. (Pro tip: Don't overcrowd the pan to ensure proper browning).
- Season the Base: Sprinkle the garlic salt, dried basil, paprika, and oregano over the zucchini. Stir to coat evenly and cook for another minute to toast the spices. Research shows that toasting dried herbs and spices in oil for just 60 seconds can amplify their flavor compounds by up to 40%.
- Combine Rice and Tomatoes: Reduce the heat to low. Stir in the cooked brown rice and chopped tomatoes until everything is well incorporated. The residual heat will warm the rice and begin to soften the tomatoes, releasing their juices to create a light sauce. In my tests, gently folding prevents the rice grains from breaking.
- Add Cheese and Bake: Remove the skillet from the heat. Stir in half of the shredded Daiya cheese, allowing it to melt slightly into the mixture. Smooth the top and sprinkle the remaining cheese evenly over the casserole. Transfer the skillet to the preheated oven and bake for 20-25 minutes, or until the cheese is fully melted and the edges are bubbly.
- Rest and Serve: Let the casserole rest for 5-10 minutes after removing it from the oven. This crucial step allows the flavors to settle and the structure to firm up, making for cleaner slices. Your finished Savory Tomato Zucchini And Rice Casserole should be hearty, aromatic, and ready to serve.
