Why You’ll Love This Recipe

  • The peppers get a head start while the filling cooks.
  • Cooked rice makes the filling easy to combine without guessing its absorption.
  • Optional chicken livers let you choose the more traditional dirty-rice flavor.

Key Ingredients

  • Cooked long-grain rice: Use cooked, chilled rice as written. Dry rice will not hydrate properly in this casserole.
  • Ground beef and sausage: Brown them for flavor and drain excess grease before adding the vegetables. Chicken livers are optional and need thorough cooking if included.
  • Bell peppers, onion, celery, and garlic: The diced vegetables flavor the filling while larger pepper pieces form the base.
  • Creole seasoning and herbs: Sausage, cheese, and seasoning blends already add salt, so taste the fully cooked filling before adding more.
  • Cheddar and pepper jack: They form the melted topping. Freshly shredded cheese distributes easily across the casserole.

Useful Tools

Use a large skillet, a baking dish, a mixing spoon, foil, and a thermometer. Only use the optional broiler finish if the baking dish is explicitly broiler-safe.

How to Make Dirty Rice Stuffed Bell Pepper Casserole

1. Start the peppers

Heat the oven to 375°F and grease the baking dish. Toss the larger pepper pieces with olive oil and a light coating of Creole seasoning. Bake uncovered for 10 minutes while you begin the filling.

2. Brown the meats

Brown the sausage over medium-high heat for 3–4 minutes, then transfer it to a plate. Cook the ground beef and optional chopped livers, breaking them up, for about 5–7 minutes or until safely cooked. Ground beef must reach 160°F; any chicken livers must reach 165°F. Drain excess grease as directed in the card.

3. Soften and season

Add butter, onion, diced peppers, and celery; cook for 5–6 minutes. Stir in garlic for 30 seconds, then return the sausage and add Worcestershire, Creole seasoning, paprika, garlic powder, onion powder, thyme, pepper, and optional cayenne. Add broth and simmer for 2–3 minutes.

4. Fold in the rice

Fold in the cooked rice, green onions, and parsley. Warm until evenly coated and moist, with no puddle of broth in the bottom. Taste only after the meat is cooked. Spread the filling over the partially roasted peppers.

5. Bake and rest

Top with cheddar and pepper jack. Cover loosely with foil and bake 20 minutes, then uncover for 8–10 minutes until melted and lightly browned. Check that the center reaches 165°F. An optional 1–2-minute broil needs a broiler-safe dish and close attention. Rest 10 minutes before serving; finish with optional garnish.

Pro Tips

  • Use cooked rice, not dry rice, so the filling stays tender.
  • Drain excess grease before adding vegetables to avoid an oily casserole.
  • Let the baked casserole rest 10 minutes so the filling settles before serving.

Ingredients  

  • Dirty Rice Filling
  • 1 pound ground beef
  • 12 ounces smoked sausage or andouille sausage diced
  • 8 ounces chicken livers finely chopped, optional but traditional
  • 1 medium yellow onion diced
  • 1 green bell pepper diced
  • 1 red bell pepper diced
  • 2 celery ribs diced
  • 1 tablespoon minced garlic
  • 2 tablespoons butter
  • 2 tablespoons Worcestershire sauce
  • 1 tablespoon Creole seasoning plus more to taste
  • 1 teaspoon smoked paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon dried thyme
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon cayenne pepper optional
  • 2 cups cooked long-grain white rice preferably chilled
  • 3/4 cup beef or chicken broth
  • 1/2 cup sliced green onions
  • 2 tablespoons chopped fresh parsley
  • Casserole
  • 3 large bell peppers any color
  • 1 tablespoon olive oil
  • Creole seasoning for lightly seasoning the peppers
  • 1 1/2 cups shredded sharp cheddar cheese
  • 1 cup shredded pepper jack cheese
  • Chopped green onions or parsley for garnish

Instructions 

  • Preheat the oven to 375°F. Lightly grease a 9-by-13-inch baking dish.
  • Cut the three large bell peppers into roughly 1-inch pieces and spread them in the prepared baking dish. Drizzle with the olive oil, season lightly with Creole seasoning, and toss to coat. Bake uncovered for 10 minutes while preparing the filling.
  • Heat a large skillet over medium-high heat. Add the diced sausage and cook for 3 to 4 minutes, stirring occasionally, until it begins to brown. Transfer the sausage to a plate.
  • Add the ground beef and chicken livers, if using, to the skillet. Cook for 5 to 7 minutes, breaking the meat apart, until browned and cooked through. Drain excessive grease, leaving about 1 tablespoon in the skillet. Check ground beef reaches 160°F and optional chicken livers reach 165°F.
  • Reduce the heat to medium. Add the butter, onion, diced green and red bell peppers, and celery. Cook for 5 to 6 minutes, stirring occasionally, until the vegetables begin to soften. Add the garlic and cook for another 30 seconds.
  • Return the sausage to the skillet. Stir in the Worcestershire sauce, Creole seasoning, smoked paprika, garlic powder, onion powder, thyme, black pepper, and cayenne, if using.
  • Pour in the broth and simmer for 2 to 3 minutes, scraping up the browned bits from the bottom of the skillet.
  • Fold in the cooked rice, green onions, and parsley. Cook just until the rice is evenly coated and the liquid has been absorbed. Taste and adjust the seasoning. The filling should be moist but not soupy. Remove it from the heat.
  • Remove the baking dish from the oven. Spoon the dirty rice mixture evenly over the partially cooked bell peppers and gently press it into an even layer.
  • Sprinkle the cheddar and pepper jack evenly over the top. Cover the dish loosely with foil and bake for 20 minutes.
  • Remove the foil and bake for another 8 to 10 minutes, or until the cheese is melted and lightly browned around the edges. For a darker top, broil for 1 to 2 minutes while watching closely. Check the center of the casserole reaches 165°F. Broil only if the baking dish is explicitly broiler-safe; otherwise skip broiling.
  • Let the casserole rest for 10 minutes. Garnish with chopped green onions or parsley and serve.

Notes

  • Use cooked rice, not dry rice, so the filling stays tender.
  • Drain excess grease before adding vegetables to avoid an oily casserole.
  • Let the baked casserole rest 10 minutes so the filling settles before serving.

Make-Ahead, Storage and Reheating

Refrigerate leftovers in shallow containers within 2 hours of cooking, or within 1 hour if the room or outdoor temperature is above 90°F. Keep the refrigerator at 40°F or below and use within 3–4 days. Do not leave a pot or skillet on the counter until completely cold. Cool rice promptly in shallow portions; cooked rice needs the same timely refrigeration as the meat.

Portion the cooked dish before freezing for longer storage. Thaw in the refrigerator. Reheat to 165°F throughout, stirring where practical and adding a little broth or water if the rice or gravy has tightened. The casserole can be reheated covered so the cheese does not dry out.

What to Serve With This Recipe

Choose a vegetable or bread to round out the meal; for a larger gathering, add a second side.

Variations and Other Dinner Ideas

Skip the optional chicken livers for a milder filling, or include them for deeper dirty-rice flavor and cook them to 165°F. Smoked sausage and andouille are both listed choices; their heat and salt levels vary. These separate recipes offer other ways to serve a hearty skillet or casserole dinner.

Frequently Asked Questions

Can raw rice cook in the casserole instead?

No. The measured broth and baking method are designed for already-cooked rice. Cook rice separately before starting if you do not have chilled rice ready.

Do the peppers need to be completely soft before layering?

No. The first bake starts softening them; they finish under the filling. Keep the pieces reasonably even so one bite is not much firmer than the next.
