Ingredients

For the Taco Casserole

• 1 lb (450 g) lean ground beef (90–93% lean) or ground turkey
• 1 tablespoon olive oil
• 1 medium onion, finely chopped
• 1 red bell pepper, diced
• 1 green bell pepper, diced
• 2 garlic cloves, minced
• 1 can (15 oz) black beans, drained and rinsed
• 1 cup sweet corn kernels
• 1 can (14.5 oz) of diced tomatoes, drained
• ¾ cup chunky salsa
• 2 tablespoons taco seasoning
• ½ teaspoon ground cumin
• ½ teaspoon smoked paprika
• ¼ teaspoon black pepper
• Salt, to taste
• 1 cup crushed baked tortilla chips
• 1 cup shredded reduced-fat Mexican cheese blend

For the Toppings

• ½ cup shredded lettuce
• ½ cup diced fresh tomatoes
• ¼ cup chopped green onions
• ¼ cup fresh cilantro
• ½ cup plain Greek yoghurt
• 1 avocado, diced (optional)
• Fresh lime wedges
• Sliced jalapeños (optional)

Optional Additions

• ½ cup cooked brown rice
• ½ cup cauliflower rice
• ¼ cup sliced black olives
• ½ teaspoon chilli flakes
• ¼ cup diced zucchini
• ¼ cup chopped mushrooms

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9×9-inch baking dish with cooking spray or a small amount of olive oil.

Set the dish aside while preparing the taco filling.

Step 2: Prepare the Vegetables

Wash the bell peppers thoroughly.

Remove the seeds and chop them into small, evenly sized pieces.

Finely dice the onion and mince the garlic.

Drain and rinse the black beans.

Drain the canned tomatoes to remove excess liquid.

Properly draining the ingredients helps prevent the casserole from becoming watery.

Step 3: Cook the Ground Beef

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

Add the lean ground beef or ground turkey.

Cook for approximately 6–8 minutes, breaking the meat into small pieces with a wooden spoon.

Continue cooking until the beef is browned and thoroughly cooked.

If using ground turkey, ensure it reaches an internal temperature of 165°F (74°C).

Drain any excess grease if necessary.

Step 4: Add the Onion and Bell Peppers

Add the chopped onion, red bell pepper, and green bell pepper to the skillet.

Cook for approximately 4–5 minutes until the vegetables begin to soften.

Stir occasionally to prevent sticking.

The vegetables add sweetness, texture, and colour to the casserole.

Step 5: Add Garlic and Seasonings

Stir in the minced garlic.

Cook for approximately 30 seconds until fragrant.

Add the taco seasoning, cumin, smoked paprika, and black pepper.

Stir thoroughly to coat the meat and vegetables.

Taste before adding additional salt because some taco seasoning blends already contain salt.

Step 6: Add Beans, Corn, and Tomatoes

Add the drained black beans, sweet corn, and diced tomatoes to the skillet.

Stir until evenly combined.

Black beans contribute fibre and plant-based protein, while corn adds natural sweetness.

Allow the mixture to cook for approximately 2 minutes.

Step 7: Add the Salsa

Pour the chunky salsa into the skillet.

Mix well until all the ingredients are coated.

Simmer for approximately 3–4 minutes.

The mixture should be moist but not excessively watery.

If too much liquid remains, continue simmering uncovered for a few minutes.

Step 8: Prepare the Tortilla Layer

Crush the baked tortilla chips into medium-sized pieces.

Avoid crushing them into fine crumbs.

Spread approximately half the crushed tortilla chips across the bottom of the prepared baking dish.

This creates a lightly crunchy base.

Step 9: Add the Taco Filling

Spoon the seasoned meat and vegetable mixture over the tortilla chips.

Spread evenly using a spatula.

Make sure the filling reaches the corners of the baking dish.

Step 10: Add the Remaining Chips and Cheese

Sprinkle the remaining crushed tortilla chips over the filling.

Top evenly with shredded reduced-fat Mexican cheese.

The cheese will melt during baking and create a delicious golden topping.

Step 11: Bake the Casserole

Place the baking dish in the preheated oven.

Bake uncovered for approximately 15–20 minutes until the cheese is completely melted and the filling is bubbling.

If you prefer a lightly golden cheese topping, broil for 1–2 minutes while watching carefully.

Step 12: Rest Before Serving

Remove the casserole from the oven.

Allow it to rest for approximately 5 minutes.

Resting helps the layers settle and makes serving easier.

Step 13: Add Fresh Toppings

Sprinkle shredded lettuce, diced tomatoes, green onions, and cilantro over the casserole.

Add small spoonfuls of plain Greek yoghurt.

If desired, garnish with diced avocado, sliced jalapeños, and fresh lime juice.

Step 14: Slice and Enjoy

Divide the casserole into six equal portions.

Serve warm with your favourite fresh toppings.

Enjoy this delicious, healthy homemade taco casserole!
