Ingredients 

  • 1 pound lean ground beef
  • 3 large bell peppers, diced (any color)
  • 1 yellow onion, diced
  • 3 cloves garlic, minced
  • 3 tablespoons Worcestershire sauce
  • 1 teaspoon smoked paprika
  • 1 teaspoon salt
  • ½ teaspoon ground black pepper
  • 1 teaspoon Italian seasoning
  • 2 ½ cups beef broth
  • 15 ounce can fire-roasted tomatoes, undrained
  • 1 cup uncooked long grain rice, rinsed
  • 2 cups shredded cheddar cheese

Instructions

  • Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with oil or cooking spray.
  • In a large skillet or Dutch oven, cook the ground beef, bell peppers, and onion over medium-high heat until the beef is browned and the vegetables begin to soften, about 7–9 minutes.
  • Add the garlic, Worcestershire sauce, smoked paprika, salt, pepper, and Italian seasoning. Stir and cook for another 1 minute, until fragrant.
  • Stir in the beef broth, fire-roasted tomatoes (with juices), and rinsed rice. Mix well to combine.
  • Transfer the mixture to the prepared baking dish and spread evenly. Sprinkle the cheddar cheese over the top.
  • Cover tightly with foil and bake for 1 hour, or until the rice is tender and most of the liquid has been absorbed.
  • Remove from the oven and let rest for 5–10 minutes before serving.

Notes

  • You can swap the ground beef for ground turkey or sausage.
  • Make it spicy by adding red pepper flakes or diced jalapeños.
  • For extra veggies, add chopped zucchini, mushrooms, or spinach with the peppers and onions.
  •  You can use any other cheese that you like or have on hand. Pepper jack would be really good on this!
  • If you can’t find the fire-roasted tomatoes, regular diced tomatoes work, but the fire-roasted variety makes a noticeable difference.
