Ingredients

For the Casserole

1 pound lean ground beef, preferably 90% lean or higher
1 cup uncooked brown rice or long-grain white rice
2 cups low-sodium beef broth
1 tablespoon olive oil
1 small yellow onion, diced
1 bell pepper, diced
2 cloves garlic, minced
1 medium zucchini, diced
1 cup frozen corn
1 can diced tomatoes, about 14.5 ounces, drained
1 can tomato sauce, about 8 ounces
1 teaspoon Italian seasoning
1 teaspoon smoked paprika
½ teaspoon ground cumin
½ teaspoon salt, or to taste
¼ teaspoon black pepper
1 cup shredded reduced-fat cheddar cheese
½ cup shredded mozzarella cheese
Chopped fresh parsley or green onions for garnish

Instructions

1. Cook the Rice

Place the rice and low-sodium beef broth in a medium saucepan. Bring the mixture to a boil, then reduce the heat to low and cover.

Cook according to the package directions until the rice is tender and has absorbed the broth. Brown rice may require approximately 35 to 45 minutes, while white rice will usually cook more quickly.

Remove the rice from the heat and set it aside.

2. Prepare the Oven and Baking Dish

Preheat the oven to 375°F.

Lightly coat a 9-by-13-inch baking dish with nonstick cooking spray or a small amount of olive oil.

3. Brown the Ground Beef

Heat one tablespoon of olive oil in a large skillet over medium heat.

Add the diced onion and bell pepper. Cook for three to four minutes, stirring occasionally, until the vegetables begin to soften.

Add the garlic and cook for approximately 30 seconds, just until fragrant.

Place the lean ground beef in the skillet. Break it apart with a wooden spoon and cook until it is browned and no longer pink. Drain any excess grease when necessary.

4. Add the Vegetables and Seasonings

Add the diced zucchini, corn, drained tomatoes, tomato sauce, Italian seasoning, smoked paprika, cumin, salt, and black pepper.

Stir everything together and allow the mixture to simmer for approximately five minutes. The zucchini should begin to soften, but it does not need to be completely cooked because it will continue cooking in the oven.

5. Combine the Beef and Rice

Add the cooked rice to the skillet and stir until it is evenly mixed with the beef, vegetables, and tomato sauce.

Taste the mixture and adjust the seasonings as needed.

6. Assemble the Casserole

Transfer the beef-and-rice mixture to the prepared baking dish. Spread it into an even layer.

Sprinkle the cheddar and mozzarella cheese evenly over the top.

7. Bake Until Hot and Cheesy

Cover the dish loosely with aluminum foil and bake for 15 minutes.

Remove the foil and bake for another 10 to 15 minutes, or until the casserole is bubbling around the edges and the cheese is completely melted.

For a lightly browned top, place the casserole under the broiler for one or two minutes. Watch it carefully to prevent the cheese from burning.

8. Rest and Serve

Allow the casserole to rest for five to ten minutes before serving. This helps the ingredients settle and makes it easier to divide into portions.

Garnish with chopped parsley or green onions.

What Makes This Casserole Healthier?

A healthy recipe is not defined by one ingredient. It is created through thoughtful choices that improve the overall balance of the meal.

Lean Ground Beef

Using beef that is at least 90% lean provides plenty of protein while reducing the amount of excess fat in the casserole. You can drain the meat after browning it to reduce the fat further.

More Vegetables

Onions, bell peppers, zucchini, tomatoes, and corn add color, flavor, texture, vitamins, minerals, and fiber. They also increase the volume of the meal, helping each serving feel generous and satisfying.

Brown Rice Option

Brown rice contains more fiber than traditional white rice. The additional fiber may help make the meal more filling and support digestive health.

White rice can still be used when that is what you have available. Portion size and the overall balance of the meal matter more than relying on one specific ingredient.

Reduced-Fat Cheese

Reduced-fat cheddar provides the familiar cheesy flavor people expect from a casserole while helping limit saturated fat. Combining cheddar with mozzarella creates a flavorful, melty topping without needing an excessive amount.

Lower-Sodium Ingredients

Using low-sodium broth, no-salt-added tomatoes, and carefully measured seasonings gives you greater control over the casserole’s sodium content.

Healthy Ingredient Substitutions

This recipe can easily be adjusted to match your family’s dietary preferences or the ingredients already in your kitchen.

Ground Turkey or Chicken

Replace the ground beef with lean ground turkey or chicken for an even lighter casserole. Because poultry is milder in flavor, you may want to add a little more smoked paprika, cumin, garlic, or Italian seasoning.

Cauliflower Rice

For a lower-carbohydrate version, replace some or all of the cooked rice with cauliflower rice.

Sauté the cauliflower rice briefly before adding it to the casserole so that excess moisture does not make the dish watery.

Quinoa

Cooked quinoa can replace the rice and provides additional protein and fiber. Its slightly nutty flavor works well with the beef, tomatoes, and cheese.

Additional Vegetables

Try adding:

Chopped spinach
Mushrooms
Broccoli
Green beans
Carrots
Peas
Diced yellow squash
Chopped kale

Spinach and kale should be stirred into the hot beef mixture and allowed to wilt before the casserole is assembled.

Black Beans

Adding a drained and rinsed can of black beans increases the fiber and stretches the casserole into additional servings. You can also reduce the amount of ground beef when adding beans.

Tips for the Best Ground Beef and Rice Casserole

Cook the Rice Before Baking

Using fully cooked rice helps ensure that the casserole has the correct texture. Uncooked rice may absorb too much liquid or remain firm unless the recipe has been specifically designed for it.

Drain the Tomatoes

Draining the diced tomatoes prevents the casserole from becoming overly watery. The tomato sauce provides enough moisture to hold everything together.

Do Not Overcook the Vegetables

The vegetables will continue cooking in the oven. Sauté them only until they begin to soften so that they retain some texture.

Let the Casserole Rest

Allowing the finished casserole to sit for several minutes helps the sauce thicken slightly and prevents the servings from falling apart.

Shred Your Own Cheese

Pre-shredded cheese is convenient, but freshly shredded cheese often melts more smoothly because it does not contain the same anti-caking ingredients.

What to Serve with Cheesy Ground Beef & Rice Casserole

This recipe already contains protein, grains, vegetables, and dairy, so it can be served as a complete meal.

For a little additional freshness, pair it with:

A simple green salad
Steamed broccoli
Roasted asparagus
Green beans with garlic
Sliced tomatoes and cucumbers
Fresh fruit
Roasted Brussels sprouts

A crisp salad with a light vinaigrette provides a refreshing contrast to the warm, cheesy casserole.

Storage Instructions

Allow the casserole to cool before placing leftovers in an airtight container.

Store it in the refrigerator for up to three or four days.

Individual portions can be reheated in the microwave. Add a teaspoon of water or broth before reheating to help prevent the rice from drying out.

To reheat a larger portion in the oven, cover the dish with foil and warm it at 350°F until heated through.

Freezing Instructions

This casserole can also be frozen for future meals.

Allow it to cool completely, then transfer individual portions to freezer-safe containers. Freeze for up to two or three months.

Thaw the casserole in the refrigerator overnight before reheating. You may need to add a small amount of broth, tomato sauce, or water to restore moisture.

For convenient lunches, freeze the casserole in individual portions.

Meal-Preparation Benefits

Cheesy Ground Beef & Rice Casserole is an excellent meal-preparation recipe because it stores well, reheats easily, and provides a complete meal in one container.

Prepare the casserole on the weekend and divide it into portions for several lunches or dinners. Add a side salad, fresh fruit, or steamed vegetables when serving.

Having a homemade meal ready can make it easier to avoid relying on takeout or highly processed convenience foods during a busy week.

Estimated Nutrition

The exact nutritional values will depend on the ingredients, brands, cheese, rice, and serving sizes used.

350 to 450 calories
25 to 30 grams of protein
30 to 40 grams of carbohydrates

Using brown rice, lean beef, reduced-fat cheese, and additional vegetables can improve the casserole’s overall nutritional balance.
