• 1 can (14.5 oz) diced tomatoes, undrained
• 1 cup beef broth
• 1 medium onion, sliced into thin strips
• Optional seasonings:
  • Salt and black pepper
  • Garlic powder (½ tsp)
  • Dried thyme or rosemary (¼ tsp)

🔪 Equipment Needed

• Large skillet or sauté pan
• Mixing spoon or spatula

• Aluminum foil
• Measuring cups and spoons

👩‍🍳 Step-by-Step Instructions

Step 1: Cook the Ground Beef and Onions

1. Preheat your oven to 350°F (175°C) .
2. In a large skillet over medium heat, cook the ground beef until browned and cooked through, breaking it apart with a spoon as it cooks.
3. Add the sliced onion and cook until softened and lightly caramelized — about 5–7 minutes.
4. Drain any excess fat from the skillet.

Step 2: Stir in Rice and Seasonings

1. Add the rice to the skillet and stir to coat it in the beef and onion mixture.
2. Season with salt, pepper, garlic powder, and any other desired spices.
3. Cook for 2–3 minutes to toast the rice slightly — this enhances its nutty flavor.

Step 3: Combine Wet Ingredients

1. Stir in the diced tomatoes (undrained) and beef broth .
2. Pour in the French onion soup , stirring well to combine everything into a thick, hearty mixture.

Tip: The soup adds both moisture and incredible flavor — no need for extra cream of mushroom or cheese sauces here!

Step 4: Transfer to Baking Dish

Pour the entire mixture into a greased 9×13-inch baking dish . Spread it out evenly with a spatula.

Step 5: Bake Until Golden and Tender

Cover the dish with aluminum foil and bake for 30 minutes . Then remove the foil and bake for another 10–15 minutes , or until the top is golden and the rice is fully cooked and fluffy.

Pro Tip: If you want a bit of crispy texture on top, place the dish under the broiler for the last 2–3 minutes (watch closely to avoid burning).

Step 6: Let Rest and Serve

Let the casserole rest for 5–10 minutes before serving. This allows it to set and makes it easier to slice or scoop.

Serve warm as a main dish, or pair it with a side salad or crusty bread for a complete meal.

🧀 Optional Toppings & Variations

• Cheesy Crust: Sprinkle shredded mozzarella or Gruyère cheese on top during the last 5 minutes of baking.
• Bacon Bits: Add crispy bacon for extra smoky flavor.
• Fresh Herbs: Garnish with chopped parsley or chives before serving.
• Vegetarian Option: Omit the beef and use lentils or mushrooms instead.

🥡 Storage & Reheating Tips

• Refrigerator: Store leftovers in an airtight container for up to 4 days .
• Freezer: Freeze individual portions for up to 3 months . Thaw overnight in the fridge before reheating.
• Reheating: Warm in the microwave (cover with a damp paper towel), or reheat in the oven at 300°F (150°C) for a crispier texture.

✅ Expert Tips for Success

• Use long-grain rice for the best texture — it stays fluffy without getting mushy.
• Don’t skip toasting the rice — it enhances flavor and helps prevent sogginess.
• If the mixture seems dry before baking, add ¼ cup more beef broth or water.
• For a richer version, mix in a splash of Worcestershire sauce or red wine.
• Always let it rest after baking — this helps the flavors meld and makes it easier to serve.
