This easy taco casserole is a one-dish dinner made with seasoned ground beef, black beans, and rice baked in a zesty salsa sauce, then topped with melted cheddar and pepper jack. The rice cooks right in the dish, so it absorbs all the taco flavor. It is simple, filling, and ideal for busy weeknights.
Rest time: The 5-minute rest after baking lets the rice finish absorbing the sauce and keeps the casserole from being runny on the plate.
Spice level: This recipe is mild to medium. Use 2 teaspoons of chili powder for a milder version, or 2 tablespoons for more heat.
Meat swaps: Ground turkey or chicken works well. Add 1 teaspoon of oil when browning, since these meats are leaner.
Rice tip: Do not rinse the rice, and do not stir it again once it is in the baking dish. Keep the foil tightly sealed so the steam cooks it evenly.
Troubleshooting: If the rice is still firm after the covered baking time, add 1/4 cup of hot broth, re-cover the dish, and bake for 5 to 10 more minutes. If the casserole looks greasy, the beef was not drained well enough, so blot the top with a paper towel before serving.
Storage: Cool the casserole within 2 hours of baking. Store leftovers in an airtight container in the refrigerator for up to 4 days.
Freezing: Cool completely, then freeze in airtight containers for up to 3 months. Thaw overnight in the refrigerator.
Reheating: Warm single portions in the microwave for about 2 minutes, stirring halfway, or in a skillet over medium-low heat with a splash of broth or water. Reheat a whole casserole covered with foil at 350°F for 30 to 40 minutes. Always heat leftovers to 165°F in the center before serving.
