Description

A hearty and flavorful stuffed pepper casserole that combines tender sautéed bell peppers, lean ground beef, aromatic spices, and fluffy rice, topped with melted cheese for a comforting one-pot meal.


Ingredients

Scale

Vegetables

  • 1 medium yellow onion, small diced
  • 2 green bell peppers, small diced
  • 2 red bell peppers, small diced
  • 4 garlic cloves, minced

Meat

  • 1 pound lean ground beef

Pantry

  • 2 teaspoons extra virgin olive oil, divided
  • 1 teaspoon kosher salt, divided
  • 2 tablespoons tomato paste
  • 1 teaspoon smoked paprika powder
  • 1 ½ cups beef stock
  • 2 teaspoons Worcestershire sauce
  • ¾ cup long-grain white rice
  • ¾ cup shredded cheese of choice


Instructions

  1. Cook Vegetables: In a large (5- or 6-quart) pot or Dutch oven with a tight fitting lid, heat 1 teaspoon of olive oil over medium-high heat. Add the diced onion and bell peppers along with ¼ teaspoon of kosher salt, and cook until just beginning to soften, about 4 minutes, stirring occasionally.
  2. Brown Ground Beef: Add the remaining 1 teaspoon olive oil, ground beef, and ¼ teaspoon salt to the pot. Stir to break the beef into small pieces and cook until browned and just cooked through, about 5 minutes, stirring occasionally.
  3. Add Aromatics: Stir in the minced garlic, tomato paste, and smoked paprika. Cook for about 1 minute until fragrant, stirring constantly to avoid burning.
  4. Add Liquids and Rice: Pour in the beef stock and Worcestershire sauce and bring the mixture to a rapid boil. Add the long-grain white rice and the remaining ½ teaspoon salt, stirring well to combine all ingredients.
  5. Simmer the Casserole: Cover the pot with a tight-fitting lid, reduce the heat to low, and simmer for 18 minutes or until the rice is just tender and liquid is absorbed.
  6. Finish with Cheese: Remove the pot from heat. Fluff the rice gently with a fork, sprinkle the shredded cheese on top, and cover again. Let sit for 7 minutes to allow the cheese to melt and the rice to become tender.
  7. Serve: Optionally garnish with chopped parsley. Serve warm, optionally topped with sour cream for extra richness.

Notes

  • Use a large pot or Dutch oven with a tight fitting lid to ensure even cooking of the rice.
  • Long-grain white rice is essential; do not use instant or par-boiled rice for best texture.
  • For a gluten-free version, choose a gluten-free Worcestershire sauce.
  • Many serve this casserole topped with sour cream, which adds a nice tangy contrast.
  • Feel free to swap out the shredded cheese for your favorite variety, such as cheddar, mozzarella, or Monterey Jack.
