How to Make Taco Rice Casserole
Step 1: Preheat the oven
Preheat your oven to 375°F. Spray a 9×13-inch baking dish with cooking spray to prevent sticking.
Step 2: Cook the beef and onion
In a large skillet, cook the lean ground beef and diced onion over medium-high heat. Stir occasionally for about 7-8 minutes until the beef is thoroughly cooked through. Drain any excess grease.
Step 3: Add garlic
Add the minced garlic to the skillet and cook for 30 seconds. Stir constantly to prevent the garlic from burning.
Step 4: Spice it up
Sprinkle the chili powder, ground cumin, smoked paprika, dried oregano, salt, and black pepper into the skillet. Cook for 1 minute until the spices become fragrant and well combined.
Step 5: Mix in rice and liquids
Stir in the uncooked long-grain rice, diced tomatoes, chopped green chilies, and beef broth. Ensure everything is evenly mixed together in the skillet.
Step 6: Transfer to baking dish
Pour the combined mixture into the prepared baking dish. Cover the dish tightly with foil and bake for 45-50 minutes, or until the rice is tender and cooked through.
Step 7: Add cheese
Remove the foil, fluff the rice with a fork, and sprinkle shredded cheese evenly over the top. Bake uncovered for an additional 8-10 minutes, or until the cheese is completely melted.
Step 8: Serve
Allow the casserole to stand for 5 minutes before serving. This helps the flavors settle and makes it easier to serve.

Pro Tips from My Kitchen
✓ Use Fresh Ingredients – Opt for fresh garlic and high-quality ground beef for the best flavor. Fresh ingredients can significantly impact the overall taste of your casserole.
✓ Experiment with Cheese – While Colby Jack is delicious, try using different cheese blends like sharp cheddar or a Mexican cheese mix for added flavor complexity.
✓ Adjust Spice Levels – If you prefer more heat, add extra chili powder or some jalapeños. For milder flavors, reduce the amount of chili powder in the recipe.
✓ Allow It to Rest – Let the casserole sit for a few minutes before serving. This resting time helps the flavors meld together and makes serving easier.
✓ Keep it Covered Until Serving – If preparing ahead of time, keep the casserole covered in the fridge until ready to bake. This helps maintain moisture and flavor during cooking.
Serving Ideas and Variations
- Pair your Taco Rice Casserole with a fresh side salad for a crunchy contrast. A simple green salad with lime dressing works wonderfully.
- For a Mexican twist, serve it with tortilla chips on the side, allowing guests to scoop out their portions or enjoy them as a crunchy topping.
- Try adding black beans or corn to the mixture for added fiber and texture. This not only enhances the nutritional value but also gives it a delightful taste.
- If you want a little more heat, top the casserole with sliced jalapeños before serving. This adds both spice and a beautiful garnish to your meal.
Frequently Asked Questions About Taco Rice Casserole
