Cuban Stuffed Rice: A Savory, Golden-Baked Rice Casserole

Cuban stuffed rice is a layered, oven-baked casserole of seasoned rice, tender chicken, mayonnaise, and melted cheese, with olives adding a briny accent. This home-style version is inspired by Cuban arroz imperial; family recipes vary, but the layers make a comforting main dish that can be assembled with straightforward ingredients.

Ingredients

1½ lb boneless, skinless chicken thighs (680 g)
4 cups water (950 ml), for poaching the chicken
1 bay leaf (about 0.2 g)
1 tsp fine salt (6 g), divided, plus more as needed
2 cups long-grain white rice (370 g), rinsed until the water runs mostly clear
3 cups reserved chicken cooking liquid or low-sodium chicken broth (710 ml)
1 tbsp neutral oil or olive oil (15 ml)
1 medium yellow onion, finely chopped (about 150 g)
1 medium green bell pepper, finely chopped (about 150 g)
3 garlic cloves, minced (about 9 g)
½ cup plain tomato sauce (120 ml)
1 tsp ground cumin (2 g)
1 tsp dried oregano (1 g)
½ tsp ground annatto, also called achiote (1 g), optional
¼ tsp ground black pepper (0.5 g)
⅓ cup sliced pimiento-stuffed green olives, drained (50 g), optional
½ cup mayonnaise (115 g)
2 cups shredded mild cheddar, Monterey Jack, or a mix (200 g)
2 tbsp chopped fresh parsley (8 g), optional, for serving

Instructions

Poach the chicken. Put the chicken thighs, water, bay leaf, and ½ teaspoon of the salt in a medium saucepan. Bring the water to a gentle boil, then lower the heat, cover partly, and simmer for 18–22 minutes, until the thickest piece reaches 165°F (74°C) on a food thermometer. USDA FSIS sets 165°F (74°C) as the safe minimum internal temperature for poultry. Transfer the chicken to a plate and let it cool enough to handle. Strain the cooking liquid and measure out 3 cups (710 ml) for the rice; add broth or water if you have less.
Cook the rice. Put the rinsed rice and measured cooking liquid in a saucepan with the remaining ½ teaspoon salt. Bring to a boil, stir once, then cover and turn the heat to low. Cook for 16–18 minutes, or until the liquid is absorbed and the grains are tender. Take the pan off the heat and leave it covered for 5 minutes, then fluff the rice gently with a fork. If your rice package gives a different liquid ratio or cooking time, follow its directions and use the poaching liquid as part of the measured liquid.
Make the chicken filling. While the rice cooks, heat the oil in a large skillet over medium heat. Add the onion and bell pepper and cook for 5–6 minutes, stirring now and then, until softened. Stir in the garlic, cumin, oregano, annatto if using, and black pepper; cook for 30 seconds. Add the tomato sauce and cook for 2 minutes, stirring, until the mixture looks cohesive rather than watery. Shred the cooled chicken with two forks, add it to the skillet, and stir to coat. Fold in the olives if using, taste, and adjust the salt.
Heat the oven and prepare the pan. While the filling finishes, heat the oven to 350°F (175°C). Lightly grease a 9-by-13-inch (23-by-33-cm) baking dish. The rice and filling should be warm, not steaming hot, when you layer them; this makes the mayonnaise easier to spread and helps the casserole bake evenly.
Build the layers. Spread about half of the rice evenly in the dish. Spoon half of the mayonnaise over it in small dollops and spread gently into a thin layer. Add all of the chicken mixture, then scatter over about half of the shredded cheese. Cover with the remaining rice, spread the rest of the mayonnaise over the top, and finish with the remaining cheese. A thin, even top layer browns more consistently than a thick mound of cheese.
Bake and rest. Bake uncovered for 20 minutes, until hot throughout and the cheese has melted. If you want a more deeply browned top, broil for 1–2 minutes at the end, watching closely so the cheese does not scorch. Let the casserole rest for 10 minutes before cutting; this gives the layers time to settle and makes portions easier to lift out.
Serve. Cut into eight portions and add chopped parsley if desired. Serve hot, making sure each portion includes rice, chicken, and some of the cheesy top.

Tips

Rinse the rice and measure the liquid. Rinsing removes loose surface starch, which helps keep the cooked grains distinct in the casserole. Measure the reserved poaching liquid after cooking the chicken; adding too much can leave the rice wet and make the layers slump.
Keep the filling moist, not soupy. The tomato sauce should season and bind the chicken, not pool in the skillet. If the mixture looks watery, simmer it for another minute or two before layering. If it seems dry, stir in a tablespoon or two of reserved broth.
Choose a practical cheese substitute. Monterey Jack melts smoothly; mild cheddar gives a more pronounced flavor. A combination works well. For a dairy-free version, use a plant-based melting cheese, though it may brown or melt differently. Annatto is optional and mainly contributes a warm yellow-orange color; if you cannot find it, leave it out rather than adding extra spices.
Make the layers neat without pressing them down. Spread the rice gently with the back of a spoon. Packing it tightly can make the casserole dense. Let the finished dish rest for 10 minutes before serving, and cool leftovers promptly rather than leaving the pan on the counter.

Serving Suggestions

This casserole is filling enough to serve as the main course. Pair it with a crisp green salad dressed with lime, or serve sliced avocado, cucumber, or ripe tomato alongside it to balance the rich cheese and mayonnaise. Black beans make a natural companion if you want a larger Cuban-inspired meal; keep them in a separate bowl so their liquid does not soften the rice layers.

For a simple table, offer lime wedges and a little extra parsley. A sharp, lightly dressed slaw also adds crunch. If you are serving guests, cut the casserole at the table after its resting time and use a broad spatula to lift each portion. The first serving may be less tidy than later slices, but the flavor and texture will be the same.

Variations

Use leftover cooked chicken. Replace the raw thighs with about 3 cups (420 g) shredded cooked chicken. Skip the poaching step and use 3 cups (710 ml) chicken broth to cook the rice. Fold the chicken into the sautéed onion, pepper, and tomato mixture, warming it until hot before assembling.

Make it with turkey. Shredded cooked turkey works in the same quantity as cooked chicken and is especially useful after a holiday meal. If starting with raw turkey, cook it thoroughly and verify the appropriate safe temperature with a thermometer before shredding; poultry must reach 165°F (74°C).

Add vegetables or a little heat. Stir ½ cup (75 g) drained corn or ½ cup (75 g) finely diced, sautéed red pepper into the filling. For gentle heat, add a pinch of red pepper flakes with the garlic. These additions change the texture and flavor but do not require changing the rice cooking method.

Adjust the topping. Use all Monterey Jack for a mild, stretchy finish, or mix it with cheddar for more savory flavor. You can reduce the mayonnaise to ⅓ cup (75 g) if you prefer a less rich casserole; spread it thinly so it does not disappear into the rice. A plant-based mayonnaise is another option, though the finished top may brown differently.

Storage and Reheating

Refrigerate the casserole within 2 hours of cooking. For faster cooling, divide it into shallow airtight containers rather than putting a deep, hot pan straight into the refrigerator. Properly refrigerated leftovers keep for 3–4 days. Rice should not be left at room temperature for an extended period, so return serving dishes to the refrigerator promptly.

To reheat a single portion, cover it loosely and microwave until steaming hot, turning or rearranging it midway through heating. For a larger amount, cover the baking dish with foil and heat at 325°F (165°C) until the center is hot. Check with a food thermometer: USDA FSIS recommends reheating leftovers to 165°F (74°C). Add a teaspoon of water or broth to a portion if the rice seems dry. You can freeze individual portions in airtight, freezer-safe containers for up to 2 months for best quality; thaw overnight in the refrigerator and reheat to 165°F (74°C).

Frequently Asked Questions

Is Cuban stuffed rice the same as arroz imperial? This recipe is a home-style version inspired by arroz imperial, a Cuban layered rice dish commonly made with rice, chicken, mayonnaise, and cheese. Recipes vary by household, including how the rice is seasoned and whether the chicken filling includes olives or other additions, so there is no single set of layers for every version.

Can I prepare it ahead of time? Yes. Cook the rice and chicken filling, cool them promptly, and refrigerate them separately for up to 1 day. Assemble the casserole shortly before baking. You can also assemble it and refrigerate it covered for up to 24 hours, but let the cold dish sit out only while the oven heats; it may need a few extra minutes in the oven, and the center should reach 165°F (74°C) when reheated.

Why did my casserole turn out mushy? The most common causes are excess liquid in the rice, a wet chicken filling, or pressing the layers firmly into the dish. Measure the rice liquid, cook the rice until it has absorbed it, and simmer the filling briefly if sauce collects in the skillet. Rinsing the rice and allowing the casserole to rest before cutting also help the portions hold together.

Can I use brown rice? You can, but brown rice needs more liquid and a longer cooking time than white rice. Cook it separately according to the package directions, using chicken broth for part or all of its liquid, then assemble the casserole as written. Because brown rice varies by brand, do not rely on the white-rice timing in this recipe.

Can I leave out the mayonnaise? You can omit it, but the layers will be less creamy and may not hold together as readily. For a similar creamy layer, use a thick dairy-free mayonnaise or a small amount of plain Greek yogurt, knowing that yogurt tastes tangier and can separate if overheated. Spread whichever option you choose thinly and evenly.
