Ingredients

2 cups cooked prime rib, chopped into bite-sized pieces
2 cups cooked white or brown rice
2 cups fresh broccoli florets
1 tablespoon olive oil or butter
1 small onion, finely chopped
2 garlic cloves, minced
1 cup shredded cheddar cheese
½ cup shredded mozzarella cheese
½ cup milk
½ cup chicken or beef broth
1 teaspoon salt
½ teaspoon black pepper
½ teaspoon paprika
½ teaspoon garlic powder
Optional garnish: chopped parsley or green onions

Directions

Prepare your skillet and aromatics
Start by heating a large skillet over medium heat. Choose a heavy-bottomed skillet if possible, as it will distribute heat evenly and help prevent sticking or burning. Add one tablespoon of olive oil or butter, depending on your preference. Allow the oil or butter to warm until it is hot but not smoking—this ensures your ingredients will sauté properly and release their natural flavors. Once the skillet is ready, add the finely chopped onions. Sauté the onions gently, stirring occasionally with a wooden spoon or heat-safe spatula. Cook until they become translucent, soft, and fragrant, which usually takes about 3–4 minutes. The aroma of onions sizzling in butter or oil will fill your kitchen and set the foundation for the rich flavors in this dish.
Incorporate garlic for depth of flavor
Once the onions are perfectly softened, add the minced garlic to the skillet. Garlic cooks very quickly, so be sure to stir constantly and allow it to cook for only 30 seconds to one minute. The goal is to release its aroma without letting it burn, which could create a bitter taste. The combination of sautéed onions and garlic forms the essential base flavor that complements the richness of the prime rib and the creaminess of the cheese in this dish.
Cook the broccoli to perfection
Next, add the fresh broccoli florets to the skillet. Stir them gently to coat with the oil or butter and allow them to mingle with the onions and garlic. Cook the broccoli for 4–5 minutes, stirring occasionally. You want the broccoli to turn a vibrant green and become slightly tender, but it should still retain a little bite, or “al dente,” for the best texture. Overcooked broccoli can become mushy and lose its bright color, so keep a close eye and taste as you go. For added flavor, you can sprinkle a small pinch of salt over the broccoli as it cooks, which helps to draw out moisture and enhance its natural taste.
Add the prime rib
Now it’s time to bring in the star ingredient: the leftover prime rib. Chop your prime rib into bite-sized pieces if you haven’t done so already. Stir the chopped beef into the skillet, making sure it is evenly distributed among the broccoli and onions. Since the prime rib is already cooked, you only need to heat it through gently—this should take about 2–3 minutes. Avoid overcooking at this stage, as the meat is already tender and flavorful. Stir occasionally to prevent the beef from sticking to the bottom of the skillet. This step ensures that every bite has a perfect balance of meat, vegetables, and aromatics.
Incorporate the rice
Next, add the cooked rice to the skillet. It’s best to use day-old rice or rice that has been cooled, as it will absorb the flavors better and maintain a firmer texture. Mix the rice thoroughly with the beef, broccoli, onions, and garlic, breaking up any clumps. Make sure the rice is evenly combined with all ingredients so that every bite has a consistent distribution of meat, vegetables, and rice. Stirring well also helps to prevent the rice from sticking to the skillet and ensures that the dish will cook evenly when the liquids are added.
Add milk and broth for creaminess
Once the rice is evenly combined, pour in ½ cup of milk and ½ cup of chicken or beef broth. Stir the mixture thoroughly to incorporate the liquid into the rice, beef, and vegetables. Allow the skillet to simmer gently for 3–4 minutes. During this time, the liquid will slightly reduce and be absorbed by the rice, creating a creamy base that binds all the ingredients together. Stir occasionally, scraping the bottom of the skillet to lift any flavorful bits that may have stuck. The milk and broth combination creates a silky texture that will be enriched further with the addition of cheese in the next step.
Melt the cheese into the mixture
Sprinkle in the shredded cheddar and mozzarella cheese evenly over the rice, beef, and broccoli. Stir continuously while the cheese melts, making sure it is fully incorporated and coats every piece of rice and vegetable. The mixture should become creamy, rich, and slightly stretchy as the cheeses melt together. Take your time with this step—stirring slowly allows the cheese to melt evenly and prevents clumping. If desired, you can add a little extra cheese at the end for an even cheesier, indulgent finish.
Season to taste
Once the cheese is fully melted and the mixture is creamy, it’s time to season. Add 1 teaspoon of salt, ½ teaspoon of black pepper, ½ teaspoon of paprika, and ½ teaspoon of garlic powder. Stir thoroughly and taste the mixture. Adjust seasoning as needed, keeping in mind that the cheese adds some saltiness and richness. Proper seasoning ensures that the flavors of the beef, broccoli, and cheese are balanced and enhanced. This step allows you to personalize the dish according to your family’s preferences—whether you prefer a slightly smoky note from paprika or a touch more garlic flavor.
Final touches and serving
Remove the skillet from the heat. If desired, garnish the dish with freshly chopped parsley or sliced green onions for a pop of color and added freshness. The final presentation not only makes the dish look appealing but also adds a subtle herbal note that complements the richness of the beef and cheese. Serve immediately while warm, ensuring that the creamy texture and melted cheese remain at their best. This dish is perfect for cozy weeknight dinners, family gatherings, or anytime you want a hearty, comforting meal that comes together in a single skillet.
Optional tips for extra flavor
For additional depth of flavor, consider adding a squeeze of fresh lemon juice over the top before serving to brighten the dish. You can also sprinkle in a few red pepper flakes for a mild heat, or add a handful of roasted nuts or seeds for a little crunch. Every step—from sautéing the aromatics to melting the cheese—can be tailored slightly to create a dish that is uniquely yours. Take your time, taste frequently, and enjoy the process as much as the finished meal.

Why This Recipe Works

The magic of this dish lies in its simplicity and flexibility. Using leftover prime rib means the beef is already cooked to perfection, so the focus is on building flavors with the sautéed onions, garlic, and fresh broccoli. The combination of cheddar and mozzarella provides a rich, creamy texture, while the paprika adds a subtle warmth without overwhelming the flavors. It’s a one-skillet meal that requires minimal cleanup, making it perfect for both weekday dinners and casual family gatherings.

Tips for the Best Hearty & Cheesy Prime Rib Beef & Broccoli Rice

Use day-old rice: Leftover rice works best as it absorbs the cheese and milk without turning mushy.
Customize your cheese: Swap cheddar or mozzarella with gouda or Monterey Jack for a different flavor profile.
Add extra vegetables: Carrots, bell peppers, or mushrooms pair beautifully with the beef and broccoli.
Make it spicy: Add a pinch of red pepper flakes or a drizzle of hot sauce for a mild kick.
Serve with a side: A fresh salad or garlic bread complements this dish perfectly.

Healthier Variations

While this recipe is indulgent, there are ways to make it a bit lighter without sacrificing flavor:

Swap white rice for brown rice or cauliflower rice to boost fiber content.
Use low-fat milk and reduce the amount of cheese slightly to lower calories.
Steam the broccoli instead of sautéing it in oil for a lighter option.

Meal Prep and Storage Tips

This dish is ideal for meal prepping, as it keeps well in the fridge for 3–4 days. Store in an airtight container and reheat in the microwave or on the stovetop.
