Key element — drain the beef, bake the cheese to the edges
Brown the beef hard, then drain off every drop of fat — a greasy base makes a greasy casserole that never sets. Spread the cheese right to the edges of the dish: it goes lacy and crisp at the rim while the centre stays bubbling, exactly like the tray in the photo.
Ingredients
Casserole
- 2 lb lean ground beef (90/10)
- 1 onion, diced
- 2 Tbsp homemade taco seasoning (chilli powder, cumin, paprika, garlic powder, oregano)
- 1 tsp salt
- ½ cup sugar-free salsa
- 4 oz cream cheese, softened
Cheese and finish
- 2 cups shredded Mexican-blend cheese
- 1 cup diced fresh tomatoes
- ¼ cup chopped fresh coriander or parsley
Swaps
- Turkey: Ground turkey (93% lean) for a leaner bake.
- Extra heat: Diced jalapeños folded through the beef.
- Loaded: Black olives and diced peppers on top before baking.
- Big finish: Shredded lettuce, sour cream and guacamole at serving.
Instructions
| 1 | Brown the beef. Heat the oven to 375°F. Brown the beef with the onion in a large skillet over medium-high heat for 8–10 minutes until deeply browned. Drain off all the fat. |
| 2 | Season taco-style. Stir in the taco seasoning, salt and salsa, and simmer for 2–3 minutes so the beef drinks up the flavour. |
| 3 | Layer the dish. Spread the beef in a greased 9×13-inch dish. Dollop the cream cheese over the top in spoonfuls — it melts into creamy pockets in the oven. |
| 4 | Cheese on top. Blanket with the Mexican-blend cheese right to the edges of the dish. |
| 5 | Bake. Bake for 18–20 minutes until the cheese is bubbling and golden at the edges. |
| 6 | Finish fresh. Rest for 5 minutes. Scatter the diced tomatoes and herbs over the top and serve straight from the dish, like the tray in the photo. |
Pro tips
- Drain the beef thoroughly — a greasy base never sets properly.
- Homemade taco seasoning beats the packet: no sugar, no starch.
- Cheese to the edges gives the crispy lacy border.
- Tomatoes go on after baking so they stay fresh and bright.
- Leftovers reheat in a skillet for the best crispy edges.
