Ingredients Method

Ingredients

  

• 1 pound ground beef (85–90% lean works well)
• 1 small yellow onion, diced
• 1 red bell pepper, diced
• 2 cloves garlic, minced
• 1 cup long-grain white rice, uncooked (jasmine or basmati also work)
• 1 (10-ounce) can diced tomatoes with green chiles (like Rotel), undrained
• 1 3/4 cups low-sodium beef broth (or chicken broth)
• 1 (15-ounce) can black beans, drained and rinsed
• 1 cup frozen corn (or canned, drained)
• 2 tablespoons tomato paste
• 2–3 tablespoons taco seasoning (store-bought or homemade)
• 1/2 teaspoon kosher salt (adjust to taste)
• 1/4 teaspoon black pepper
• 1 1/2 cups shredded cheese (cheddar, Monterey Jack, or a Mexican blend)
• 2 tablespoons chopped cilantro (optional, for garnish)
• Optional toppings: sour cream, avocado, jalapeños, green onions, hot sauce, lime wedges

Method

 

1. Preheat the oven. Set your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish or use an oven-safe skillet for a true one-pan meal.
2. Brown the beef. In a large skillet over medium-high heat, cook the ground beef, breaking it up with a spatula, until no longer pink. Spoon off excess fat if needed.
3. Add aromatics and veggies. Stir in the onion and bell pepper. Cook 4–5 minutes until softened. Add garlic and cook 30 seconds until fragrant.
4. Season it right. Mix in taco seasoning, salt, pepper, and tomato paste. Stir to coat the meat and veggies so the spices bloom and the paste darkens slightly.
5. Add rice and liquids. Pour in the uncooked rice, canned tomatoes with their juices, and broth. Stir well, scraping up any browned bits from the bottom of the pan.
6. Fold in beans and corn. Add black beans and corn. Bring the mixture to a gentle simmer.
7. Transfer and cover. If your skillet isn’t oven-safe, pour the mixture into the prepared baking dish. Cover tightly with foil. This helps the rice steam and cook evenly.
8. Bake until tender. Bake 25–30 minutes, or until the rice is cooked and most of the liquid is absorbed. If the rice still has bite, cover and bake an additional 5–10 minutes.
9. Add cheese and finish. Remove the foil, sprinkle cheese evenly on top, and bake uncovered another 5–8 minutes, until melted and bubbly.
10. Garnish and serve. Let the casserole rest 5 minutes. Sprinkle with cilantro and serve with your favorite toppings. A squeeze of lime wakes up the flavors.

Why This Recipe Works

This casserole blends familiar taco flavors with the comfort of a baked dish, so it feels special without any fuss. Using rice instead of tortillas keeps it budget-friendly and filling.

Canned tomatoes with green chiles add tang and heat while saving time on prep. Everything cooks in one skillet before it hits the oven, so cleanup stays easy. It also reheats well, making it great for meal prep or next-day lunches.

Ingredients

• 1 pound ground beef (85–90% lean works well)
• 1 small yellow onion, diced
• 1 red bell pepper, diced
• 2 cloves garlic, minced
• 1 cup long-grain white rice, uncooked (jasmine or basmati also work)
• 1 (10-ounce) can diced tomatoes with green chiles (like Rotel), undrained
• 1 3/4 cups low-sodium beef broth (or chicken broth)
• 1 (15-ounce) can black beans, drained and rinsed
• 1 cup frozen corn (or canned, drained)
• 2 tablespoons tomato paste
• 2–3 tablespoons taco seasoning (store-bought or homemade)
• 1/2 teaspoon kosher salt (adjust to taste)

How to Make It

1. Preheat the oven. Set your oven to 375°F (190°C).

   Lightly grease a 9×13-inch baking dish or use an oven-safe skillet for a true one-pan meal.

2. Brown the beef. In a large skillet over medium-high heat, cook the ground beef, breaking it up with a spatula, until no longer pink. Spoon off excess fat if needed.
3. Add aromatics and veggies. Stir in the onion and bell pepper. Cook 4–5 minutes until softened.

   Add garlic and cook 30 seconds until fragrant.

4. Season it right. Mix in taco seasoning, salt, pepper, and tomato paste. Stir to coat the meat and veggies so the spices bloom and the paste darkens slightly.
5. Add rice and liquids. Pour in the uncooked rice, canned tomatoes with their juices, and broth. Stir well, scraping up any browned bits from the bottom of the pan.
6. Fold in beans and corn. Add black beans and corn.

   Bring the mixture to a gentle simmer.

7. Transfer and cover. If your skillet isn’t oven-safe, pour the mixture into the prepared baking dish. Cover tightly with foil. This helps the rice steam and cook evenly.
8. Bake until tender. Bake 25–30 minutes, or until the rice is cooked and most of the liquid is absorbed. If the rice still has bite, cover and bake an additional 5–10 minutes.
9. Add cheese and finish. Remove the foil, sprinkle cheese evenly on top, and bake uncovered another 5–8 minutes, until melted and bubbly.
10. Garnish and serve. Let the casserole rest 5 minutes.

    Sprinkle with cilantro and serve with your favorite toppings. A squeeze of lime wakes up the flavors.

How to Store

• Refrigerator: Cool completely, then store in an airtight container for 3–4 days.
• Freezer: Portion into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
• Reheating: Microwave individual portions with a splash of water or broth, covered, until hot.

  For the oven, cover and warm at 325°F (165°C) for 15–20 minutes.

• Meal prep tip: Keep fresh toppings separate so they stay crisp when you reheat.

Why This is Good for You

This casserole balances protein, carbs, and fiber in a satisfying way. Ground beef brings iron, zinc, and B vitamins that support energy and muscle health. Black beans and corn add fiber to keep you full and support digestion. Bell peppers and tomatoes bring vitamin C and antioxidants. You also control the sodium, spice level, and cheese, so it fits your goals without feeling restrictive.

Common Mistakes to Avoid

• Using the wrong rice. Stick to long-grain white rice for predictable cooking. Brown rice needs more liquid and time.
• Skipping the foil. If you don’t cover the dish, the rice can cook unevenly and dry out.
• Not draining grease. Too much fat can make the casserole heavy and greasy.

  Drain if your beef is very fatty.

• Overloading the cheese. Cheese is great, but too much can make the top oily. 1 to 1 1/2 cups is the sweet spot.
• Forgetting to rest. A brief rest helps the rice settle and the juices redistribute, so scoops hold together.

Alternatives

• Protein swaps: Use ground turkey or chicken for a lighter take. For vegetarian, skip the beef and add an extra can of beans or crumbled tofu.
• Rice options: For brown rice, increase broth to about 2 1/4 cups and bake longer (45–55 minutes), checking for tenderness.
• Spice level: Use mild tomatoes without chiles for less heat, or add diced jalapeños and a pinch of cayenne for more kick.
• Cheese choices: Pepper Jack adds heat, Oaxaca melts beautifully, and a blend gives a nice stretch.
• Add-ins: Stir in zucchini, spinach, or diced green chiles. A few tablespoons of salsa or enchilada sauce deepens the flavor.
• Toppings: Shredded lettuce, pico de gallo, pickled onions, or crushed tortilla chips add freshness and crunch.
• Gluten-free note: This recipe is naturally gluten-free if your taco seasoning and broth are certified GF.

FAQ

Can I make this ahead?

Yes.

Assemble through step 7, cool, and refrigerate up to 24 hours. Bake covered for 30–35 minutes, then add cheese and finish. You may need a few extra minutes since it starts cold.

What if my rice isn’t fully cooked?

Add 1/4 cup more hot broth or water, cover tightly, and bake 5–10 more minutes.

Check again and repeat if needed. Every oven runs a little different, so small adjustments help.

Can I use pre-cooked rice?

You can, but reduce the broth to about 1/2 cup, skip the long bake, and simmer the filling on the stove until thick. Fold in cooked rice, top with cheese, and bake uncovered 10 minutes to melt.

How do I make it spicier?

Use hot taco seasoning, fire-roasted tomatoes with hot chiles, and Pepper Jack cheese.

Add minced jalapeño or a dash of chipotle powder for smoky heat.

What sides go well with this?

Keep it simple with a crisp green salad, sautéed zucchini, or a bowl of chopped tomatoes and cucumbers. Chips and guacamole or a quick corn salad also pair nicely.

Can I cook it entirely on the stovetop?

Yes. After adding rice and liquids, cover and simmer on low, stirring occasionally, until the rice is tender.

Sprinkle with cheese, cover, and let it melt off the heat for a few minutes.

Is there a dairy-free option?

Use a dairy-free shredded cheese or skip the cheese and finish with creamy avocado, extra salsa, and a drizzle of cashew crema.

How can I reduce the sodium?

Choose low-sodium broth and beans, and make your own taco seasoning. Taste before salting, since cheese and canned tomatoes also add saltiness.

In Conclusion

Ground Beef Taco Rice Casserole delivers big flavor with minimal effort. It’s flexible, affordable, and perfect for feeding a hungry crew.
