- Total Time: 55 minutes
Yield
Serves 6 generous portions.
Difficulty Level
Easy – perfect for home cooks of all skill levels.
Ingredients
- 3 cups cooked leftover rice, chilled
- 1 cup shredded sharp cheddar cheese
- 1 cup chopped cooked chicken breast (optional)
- 1 cup diced bell peppers (mixed colors)
- 1/2 cup finely chopped onion
- 2 cloves garlic, minced
- 1 1/2 cups whole milk
- 1/2 cup sour cream or Greek yogurt
- 2 tbsp all-purpose flour
- 2 tbsp unsalted butter
- 1 tsp dried thyme
- 1/2 tsp smoked paprika
- Salt and freshly ground black pepper to taste
- Fresh parsley, chopped, for garnish
Instructions
- Preheat the oven to 375°F (190°C). Lightly grease a 9×13 inch casserole dish with butter or nonstick spray.
- Make the creamy sauce: In a medium saucepan over medium heat, melt the butter. Add the chopped onion and sauté until translucent, about 3-4 minutes. Stir in the minced garlic and cook for another 1 minute until fragrant.
- Whisk in the flour and cook for 1-2 minutes, stirring constantly to avoid lumps. Gradually whisk in the milk until smooth and simmer gently until thickened, about 5 minutes.
- Remove from heat and fold in the sour cream, dried thyme, smoked paprika, salt, and pepper. Adjust seasoning as needed.
- Combine the base: In a large mixing bowl, gently toss the leftover rice with the diced bell peppers, cooked chicken (if using), and half of the shredded cheese.
- Pour the sauce over the rice mixture and stir until everything is evenly coated.
- Transfer the mixture to the prepared casserole dish and smooth the top with a spatula. Sprinkle the remaining cheese evenly over the surface.
- Bake uncovered in the preheated oven for 30-35 minutes, or until the casserole is bubbly and the cheese is melted and golden.
- Let cool for 5 minutes before serving. Garnish with fresh chopped parsley for a bright, herbaceous finish.
Tips for Success
- Choosing your rice: Long grain rice works well, but jasmine or basmati add a fragrant twist. Make sure rice is cold to prevent clumping.
- Protein swap: Substitute chicken with cooked sausage, ground beef, or skip meat entirely for a vegetarian option.
- Dairy alternatives: Use coconut milk and vegan cheese to make it dairy-free without losing creaminess.
- Make-ahead magic: Assemble the casserole a day before and refrigerate. Add 5-10 minutes to baking time if baking straight from the fridge.
- Add texture: Top with breadcrumbs mixed with melted butter for a golden, crunchy crust.
Serving Suggestions
Serve this rice casserole as a satisfying main dish alongside a crisp green salad or steamed seasonal vegetables. For extra brightness, squeeze fresh lemon over each serving or drizzle with hot sauce to add a spicy kick. Garnish with freshly chopped herbs like parsley or chives for both color and flavor contrast.

Q&A
Q&A: Transform Leftover Rice Into a Delicious Casserole Dish
Q1: Why is leftover rice perfect for making a casserole?
A1: Leftover rice is already cooked and slightly dried out, making it an excellent base that readily absorbs flavors and binds well with other ingredients. This prevents the casserole from becoming too mushy and helps create a delightful texture contrast.
Q2: What ingredients pair best with leftover rice in a casserole?
A2: The beauty of rice casseroles lies in their versatility. You can mix in vegetables like peas, bell peppers, and mushrooms; proteins such as shredded chicken, ground beef, or tofu; and a creamy binder like cheese, cream of mushroom soup, or béchamel sauce. Herbs and spices add the final flavor punch.
Q3: How can I make the casserole rich and creamy without it becoming soggy?
A3: To keep it creamy yet firm, use just enough sauce to coat the rice and other ingredients without saturating. Incorporate ingredients that hold moisture well, like cream cheese or yogurt, and bake uncovered or loosely covered to allow excess moisture to evaporate.
Q4: Can I prepare this casserole ahead of time with leftover rice?
A4: Absolutely! This dish is a perfect make-ahead meal. Assemble your casserole in advance, cover it tightly, and refrigerate for up to two days. When ready, bake it until bubbling and golden – it tastes like homemade comfort food fresh out of the oven.
Q5: What’s a simple tip to add a crunchy topping to the casserole?
A5: Sprinkle a mixture of breadcrumbs, grated Parmesan, and a drizzle of olive oil or melted butter over your casserole before baking. This creates a golden, crispy crust that adds a delightful contrast to the creamy, tender rice beneath.
Q6: Is this casserole recipe suitable for special diets?
A6: Definitely! With a few tweaks, you can make it gluten-free by using gluten-free breadcrumbs or omit them entirely. Use dairy-free cheese and plant-based cream alternatives for a vegan version. Just switch up the protein and veggies to suit your preferences.
Q7: What’s the best way to reheat leftover rice casserole?
A7: To preserve its texture and flavor, reheat gently in an oven at 350°F (175°C) covered with foil to avoid drying out. Alternatively, microwave portions covered with a damp paper towel, stirring halfway through, ensures even heating.
