Step-by-Step Directions

  1. Prep the Oven and Dish: Preheat oven to 350°F. Grease a 3-quart baking dish with olive oil to prevent sticking.
  2. Sauté Veggies: In a large skillet, heat olive oil over medium. Sauté onion, red bell pepper, and green bell pepper until softened (about 3–5 minutes).
  3. Cook the Beef: Add ground beef and break up with a spoon. Cook until browned (6–8 minutes). Drain excess fat if needed.
  4. Flavor Base: Stir in tomato paste, salt, cumin, paprika, black pepper, and garlic. Cook until fragrant (about 1 minute).
  5. Add Veggies: Mix in tomatoes and zucchini. Cook until veggies soften (about 3–5 minutes).
  6. Combine and Layer: Add chicken broth, uncooked rice, parsley/cilantro, Worcestershire sauce, and 1 cup shredded cheese. Mix well, then transfer to prepared casserole dish. Cover tightly with foil.
  7. Bake: Bake covered so the rice steams, about 50–60 minutes, until rice is tender and liquid absorbed.
  8. Finish for Cheesiness: Remove foil, stir, and sprinkle remaining cheese on top. Broil for 2–3 minutes until cheese is bubbling and golden.
  9. Garnish and Serve: Cool for 5 minutes. Garnish with extra parsley or cilantro. Serve hot for ultimate comfort.

Tips, Variations, and Make-Ahead Advice

  • No Pre-Cooking Rice: Add rice uncooked; it bakes with the casserole for ease and ideal texture.
  • Make-Ahead: Although best baked immediately to cook rice perfectly, you can bake ahead, cool, and refrigerate for up to 2 days. Reheat covered in a 350°F oven for 20–30 minutes.
  • Vegetable Options: Substitute other veggies like mushrooms, squash, or spinach if desired.
  • Cheese Choices: Swap pepper jack for cheddar, Monterey Jack, or even mozzarella.
  • Lean Protein: Ground turkey or chicken work well as beef substitutes.
  • Spice It Up: Add diced jalapeños or hot sauce for extra kick.
  • Gluten-Free: Recipe is naturally gluten-free if you use gluten-free Worcestershire sauce.
