Ingredients
Instructions
- Preheat oven. Preheat to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
- Brown the beef. Cook the ground beef and onion in a skillet until no longer pink. Drain extra fat. Stir in taco seasoning and water or broth and simmer 2–3 minutes until thickened.
- Layer. Spread the seasoned beef in the baking dish. Dollop or spread the sour cream (and cream cheese if using) over the meat. Sprinkle with most of the shredded cheese.
- Bake. Bake 18–25 minutes until the cheese is melted and bubbly around the edges.
- Top and serve. Finish with remaining cheese if desired, then add tomato, olives, jalapeño, cilantro, and avocado. Rest 5 minutes, then slice and serve.
Notes & Tips
- Drain the beef well so the casserole isn’t greasy.
- Use a sugar-free taco seasoning to keep carbs low.
- Add fresh toppings after baking so they stay bright and crisp.
- Let it rest a few minutes before cutting so the layers hold.
- This reheats well — add a little extra cheese when warming leftovers.
Variations & serving ideas
- Higher protein: Use extra-lean beef or mix in ground turkey.
- Spicy: Add extra jalapeños or a pinch of cayenne to the seasoning.
- Chicken taco: Swap the beef for cooked shredded chicken.
- Cauliflower layer: Add a thin layer of riced cauliflower under the beef if you want more volume.
- Taco salad bake: Serve each slice over shredded lettuce with extra salsa and avocado.
- Buffalo taco: Stir a little hot sauce into the beef and finish with ranch instead of sour cream.
- Turkey taco: Use ground turkey and add extra seasoning for a leaner version.
