Step-by-Step Instructions

Step 1: Preheat and Prepare

Preheat your oven to 400 degrees F. Lightly grease a medium baking dish and set it aside.

Step 2: Cook the Vegetables

Heat the olive oil in a large skillet over medium heat. Add the chopped onion and cook for about 3 minutes until softened. Stir in the garlic and bell pepper and cook for another 2 minutes until fragrant.

Step 3: Brown the Beef

Add the ground beef to the skillet. Break it apart with a spoon and cook until fully browned. Drain excess fat if needed.

Step 4: Add Spices and Sauce

Sprinkle the spice mix over the beef and stir well so everything is evenly coated. Add the tomato passata, beans, and jalapeños. Simmer for 5 minutes, allowing the flavors to blend.

Step 5: Assemble the Casserole

Transfer the beef and bean mixture into the prepared baking dish. Spread it evenly, then sprinkle the shredded cheese over the top.

Step 6: Bake

Place the casserole in the oven and bake for 15 to 20 minutes, or until the cheese is melted and bubbling.

Step 7: Rest and Serve

Let the casserole rest for 5 minutes before serving. Garnish with fresh cilantro or your favorite toppings.

Pro Tips for Success

• Use a wide skillet to brown the beef evenly and quickly.
• Taste the mixture before baking and adjust seasoning as needed.
• For extra cheesiness, mix some cheese into the beef mixture before baking.
• Letting the casserole rest helps it set and makes serving easier.
• Double the recipe and freeze one for later.

Flavor Variations

• Add a half teaspoon of chipotle powder for smoky heat.
• Stir in a half cup of corn kernels for sweetness and texture.
• Use taco seasoning if you want an even quicker option.
• Top with crushed tortilla chips before baking for crunch.
• Mix in cooked rice to make it extra filling.
