Ingredients

1 lb ground beef (80/20 for maximum flavor)
1 onion, diced (white or yellow, no one’s judging)
1 bell pepper, diced (red for sweetness, green for crunch)
2 cloves garlic, minced (or 1 tsp pre-minced, we won’t tell)
1 packet taco seasoning (or DIY with chili powder, cumin, paprika)
1 can black beans, drained (because fiber is your friend)
1 can diced tomatoes (fire-roasted for extra drama)
1 cup corn (fresh, frozen, or canned—your call)
2 cups cooked rice (white, brown, or cauliflower for low-carb)
2 cups shredded cheese (cheddar, Monterey Jack, or a mix)
Tortilla chips (for crushing on top, obviously)
Sour cream, cilantro, jalapeños (optional, but highly recommended)

Step-by-Step Instructions

Brown the beef: In a skillet, cook the ground beef over medium heat until no pink remains. Drain excess fat (unless you’re into that).
Sauté the veggies: Add onion, bell pepper, and garlic. Cook until soft, about 5 minutes.
Your kitchen should smell amazing by now.
Season it up: Stir in taco seasoning, black beans, diced tomatoes, and corn. Let it simmer for 3–4 minutes.
Layer the casserole: In a baking dish, spread cooked rice as the base. Top with the beef mixture, then sprinkle cheese like you’re making it rain.
Crunch time: Crush tortilla chips over the top for that irresistible texture.
Bake: Pop it in the oven at 375°F for 15–20 minutes, or until the cheese is bubbly and golden.
Garnish and serve: Add sour cream, cilantro, or jalapeños if you’re feeling fancy.
Dig in.

Storage Instructions

Store leftovers in an airtight container in the fridge for up to 3–4 days. Reheat in the microwave or oven (pro tip: the oven keeps the chips crispy). For longer storage, freeze individual portions for up to 2 months.

Thaw overnight in the fridge before reheating.

Nutrition Stats

Per serving (1/6 of the casserole): ~450 calories, 25g protein, 35g carbs, 22g fat. Numbers vary based on ingredients (e.g., using cauliflower rice slashes carbs). FYI, this isn’t health food, but it’s balanced enough to avoid guilt.

Common Mistakes to Avoid

Overcooking the beef: Dry, crumbly meat is a tragedy.
Stop cooking as soon as the pink disappears.
Skipping the chip topping: Without the crunch, it’s just a sad taco bowl. Don’t do that to yourself.
Using watery tomatoes: Drain them, or your casserole will swim in liquid.
Underseasoning: Taste as you go. Bland food is a crime.

Alternatives

Swap ground beef for ground turkey, chicken, or plant-based crumbles.

Use quinoa instead of rice, or skip the grains entirely for a keto version. Hate black beans? Try pinto or kidney beans.

Cheese alternatives work too—just don’t expect the same meltiness.

FAQs

Can I make this ahead?

Absolutely. Assemble the casserole, cover, and refrigerate for up to 24 hours before baking. Add 5–10 minutes to the cooking time if it’s cold from the fridge.

What if I don’t have taco seasoning?

Mix 1 tbsp chili powder, 1 tsp cumin, 1 tsp paprika, ½ tsp garlic powder, and a pinch of cayenne.

Boom—DIY seasoning.

Is it spicy?

Depends on your taco seasoning and toppings. For mild, skip jalapeños and use a mild seasoning. For heat, add diced green chiles or hot sauce.

Can I freeze it?

Yes!

Freeze before or after baking. Thaw in the fridge overnight and reheat covered with foil to prevent drying out.
