This easy taco casserole is a one-dish dinner made with taco-seasoned ground beef, black beans, and rice baked in a zesty salsa sauce, then topped with melted cheese. It’s simple for busy weeknights, feeds a family, reheats well, and delivers roughly 25 grams of protein per serving (an estimate, based on 6 servings).
What Makes This Taco Casserole Great?
The rice bakes right in the seasoned salsa and broth, so it tastes like taco night instead of plain rice under taco meat. A homemade taco seasoning keeps the flavor bold without the salt overload of packets, and a squeeze of lime at the end keeps it fresh.
- Stretches one pound of beef to feed 6 people, thanks to the rice and beans.
- Works for meal prep, since it reheats well and tastes just as good on day three.
- Easy to adjust for different spice levels, keep the casserole mild and let everyone add hot sauce or jalapeños at the table.
- Built mostly from pantry staples like canned beans, salsa, rice, and spices.
- Freezer-friendly, so you can bake one now and have a backup dinner later.
The Taco Meat
Ground beef is the savory base here. Using 85% lean gives you enough fat for flavor, and you drain the extra so the casserole doesn’t turn greasy. Onion and bell pepper cook right alongside it for a little sweetness.
Cooking the spices in the skillet matters more than you’d think. A minute in the hot pan wakes them up, and the kitchen starts smelling like a taco truck. So good.
What You’ll Need for the Taco Meat
- 1 lb 85% lean ground beef, has enough fat for flavor and is easy to drain.
- 1 medium yellow onion, diced, adds sweetness as it softens.
- 1 medium green bell pepper, diced, brings a fresh, slightly grassy flavor that suits tacos.
- 3 cloves garlic, minced, gives the meat a rounder, savory flavor.
- 1 1/2 tablespoons chili powder, the main taco flavor in the dish.
- 2 teaspoons ground cumin, adds warm, earthy depth.
- 1 teaspoon smoked paprika, brings gentle smokiness without much heat.
- 1/2 teaspoon onion powder, rounds out the seasoning.
- 1/2 teaspoon dried oregano, adds a light herby note that balances the cumin.
- 3/4 teaspoon salt, seasons the beef and rice.
- 1/4 teaspoon black pepper, adds a little background bite.
The Rice and Salsa Sauce
Long-grain white rice works best because it stays fluffy and separate instead of turning sticky. It soaks up the broth, salsa, and tomato sauce as it bakes, and that’s where most of the flavor comes from.
Salsa is the secret taco shortcut here. It brings tomato, onion, and a little heat in one jar. Trust me on using a salsa you’d happily eat with chips, since the flavor carries through.
What You’ll Need for the Rice and Salsa Sauce
- 1 1/4 cups uncooked long-grain white rice, stays fluffy and absorbs the liquid well. Do not rinse it, the surface starch helps hold the casserole together.
- 2 1/2 cups low-sodium beef broth, cooks the rice and adds savory depth.
- 1 cup medium salsa, adds tomato flavor, tang, and mild heat.
- 1 can (8 oz) tomato sauce, gives the sauce body so it coats the rice.
- 1 can (4 oz) chopped green chiles, adds gentle tangy heat without making it spicy.
- 1 can (15 oz) black beans, drained and rinsed, adds protein, fiber, and a soft, creamy bite.
The Cheese Topping
The cheese goes on at the end so it melts into a golden, bubbly layer without turning rubbery. Cheddar and pepper jack together give you a sharp, classic taste with a gentle kick. Shredding it from a block makes a noticeable difference, since packaged shreds don’t melt as smoothly.
What You’ll Need for the Cheese Topping
- 3/4 cup shredded sharp cheddar, melts well and adds a tangy, familiar flavor.
- 3/4 cup shredded pepper jack, adds creaminess and a mild spicy kick.
How to Make Taco Casserole
Prep the Oven and Dish
Preheat the oven to 375°F and lightly grease a 9×13-inch baking dish with cooking spray. Keep a sheet of foil nearby, because the rice goes in quickly once the sauce is ready.
Brown the Taco Meat
Heat a large, deep skillet over medium-high heat and add the ground beef, onion, and bell pepper.
Cook for 7 to 8 minutes, breaking up the beef with a spoon, until no pink remains and the vegetables are soft. The beef should reach 160°F. Tilt the pan and spoon out the extra grease, leaving a little behind for flavor.
Toast the Taco Spices
Lower the heat to medium and stir in the garlic. Cook for 30 seconds, then add the chili powder, cumin, smoked paprika, onion powder, oregano, salt, and pepper. Stir constantly for about 1 minute, until everything smells fragrant.
Simmer the Sauce
Pour in the broth, salsa, tomato sauce, and green chiles. Scrape up any browned bits from the bottom of the pan, then bring the mixture to a gentle simmer for about 2 minutes. This warms the liquid so the rice cooks evenly in the oven.
Add the Rice and Beans
Stir in the uncooked rice and drained black beans until everything is evenly mixed. Pour the mixture into the prepared baking dish and spread it flat. Make sure the rice is fully submerged in the liquid, since any grains poking out may stay crunchy.
Bake Covered
Cover the dish very tightly with foil so the steam stays trapped. Bake for 45 to 50 minutes, until the rice is tender and has absorbed nearly all the liquid. If it still looks soupy, re-cover it and bake for another 5 minutes.
Melt the Cheese
Remove the foil and fluff the rice gently with a fork. Sprinkle the cheddar and pepper jack evenly over the top and bake uncovered for 8 to 10 minutes, until the cheese is melted and bubbling at the edges.
Let it rest for 5 minutes before serving, so it holds together when scooped.
Variations and Customizations
This taco casserole is flexible, so you can swap things based on what’s in your kitchen. Keep the rice and liquid amounts the same, since that ratio is what makes the rice cook properly. Everything else can change with a little thought.
- Use ground turkey or chicken instead of beef, and add 1 teaspoon of oil when browning since they are leaner.
- Swap the black beans for pinto beans or kidney beans.
- Replace the beef broth with chicken broth for a milder flavor.
- Stir in 1 cup of frozen corn with the rice for extra sweetness and texture.
- Use 2 teaspoons of chili powder for a mild, kid-friendly version, or 2 tablespoons for more heat.
- Go vegetarian by skipping the beef, using vegetable broth, and adding a second can of beans.
- Use Monterey Jack, a Mexican cheese blend, or all cheddar if that’s what you have.
Storing, Reheating, and Meal Prep
Let the casserole cool for no more than 2 hours at room temperature, then move leftovers to an airtight container. It keeps in the refrigerator for up to 4 days. For meal prep, portion it into individual containers and keep fresh toppings like lettuce, avocado, and cilantro separate until you’re ready to eat.
To freeze, cool the casserole completely, then pack it into airtight containers or wrap the whole dish tightly in plastic wrap and foil. It freezes well for up to 3 months. Thaw it overnight in the refrigerator, then reheat individual portions in the microwave for about 2 minutes, stirring halfway, or in a skillet with a splash of broth or water to keep the rice from drying out. A whole casserole can be covered with foil and baked at 350°F for 30 to 40 minutes. Either way, make sure it reaches 165°F in the center before serving.
