Step-by-Step Instructions
Brown the Beef
Heat a large skillet over medium heat and add ground beef. Cook while breaking apart with a spatula until mostly browned and developing good color, about 5-7 minutes.
Add Vegetables
Add chopped onions and bell peppers directly to the skillet with the beef. Cook for 5-10 minutes, stirring occasionally, until vegetables begin to soften and become aromatic.
Build Flavor Base
Stir in minced garlic and cook for 1-2 minutes until fragrant. Be careful not to burn the garlic, which would create bitter flavors.
Combine All Elements
Add Worcestershire sauce, Italian seasoning, salt, pepper, beef broth, diced tomatoes, and uncooked rice. Mix thoroughly to ensure even distribution of ingredients and seasonings.
Cook the Rice
Increase heat to bring mixture to a boil, then cover and reduce to a simmer. Cook for 20 minutes, stirring once halfway through. The rice should be tender and have absorbed most of the liquid.
Add First Cheese Layer
Remove lid and stir in half of both the mozzarella and cheddar cheeses until completely melted and incorporated into the mixture.
Finish with Cheese Topping
Sprinkle remaining cheese evenly over the surface. Cover and allow to melt naturally, or if using an oven-safe skillet, place under broiler briefly for quicker melting and browning.
Recipe Notes & Tips
