How to Make the Recipe

Step 1

Preheat your oven to 375°F (190°C).

Step 2

In a skillet over medium heat, warm olive oil and sauté the thinly sliced onions until golden and softened.

Step 3

Add ground beef to the skillet. Cook until browned, breaking it apart as it cooks. Drain excess grease if needed.

Step 4

Season the beef mixture with garlic powder, onion powder, dried thyme, salt, and pepper. Stir to combine.

Step 5

In a large casserole dish, combine the uncooked rice, cooked beef and onion mixture, and beef broth. Mix thoroughly.

Step 6

Cover with foil and bake for 40–45 minutes, or until the rice is tender and liquid is absorbed.

Step 7

Remove foil, sprinkle shredded Swiss cheese evenly over the top, and bake uncovered for an additional 10 minutes until cheese is melted.

Step 8

Top with French fried onions and return to the oven for 5 more minutes to crisp up.

Step 9

Garnish with fresh parsley and serve hot.

Tips for Making the Recipe

• Use freshly sliced onions for best flavor—avoid pre-packaged or frozen if possible.
• Don’t overcook the beef; it will continue to cook in the oven.
• Let the casserole rest for 5–10 minutes before serving to allow the flavors to settle.
• If using brown rice, increase the liquid and cooking time.
• Add more broth if the casserole looks dry while baking.

How to Serve

Serve this casserole as a standalone main dish, or pair it with:

• A crisp green salad
• Steamed green beans or broccoli
• Garlic bread or dinner rolls
• A light soup starter like tomato basil

Make Ahead and Storage

Storing Leftovers

Store cooled leftovers in an airtight container in the refrigerator for up to 4 days.

Freezing

Wrap the casserole tightly in foil and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

Reheat individual portions in the microwave, or warm the entire dish in the oven at 350°F (175°C) until heated through.
