Key element — drain the beef
Extra fat from the meat will pool under the eggs and keep the center from setting. Brown the beef well, drain it, then layer.
Ingredients
Beef layer
- 1½ lb (680g) lean ground beef
- 2 Tbsp sugar-free taco seasoning
- 2 Tbsp water
- ½ small onion, finely diced (optional)
Egg layer
- 8 large eggs
- ½ cup cottage cheese or full-fat Greek yogurt
- ¼ cup heavy cream
- ½ tsp salt
- ½ tsp garlic powder
- ¼ tsp black pepper
Topping
- 1½ cups shredded cheddar
- ½ cup diced tomato
- 1 jalapeño, sliced
- 2 green onions, sliced
Swaps
- Higher protein: Use extra-lean beef and cottage cheese instead of cream only.
- Turkey: Ground turkey works the same way.
- Sausage: Swap half the beef for breakfast sausage.
- Mild: Skip the jalapeño and use extra tomato.
Instructions
| 1 | Preheat and cook the beef. Heat the oven to 375°F (190°C). Brown the beef with onion if using. Drain extra fat, then stir in taco seasoning and water. Spread in a greased 9-inch pie dish or 8×8-inch pan. |
| 2 | Mix the eggs. Whisk eggs, cottage cheese or yogurt, cream, salt, garlic powder, and pepper until combined. Pour over the beef. |
| 3 | Add cheese. Sprinkle cheddar evenly over the top. |
| 4 | Bake and garnish. Bake 22–28 minutes until the center is set and the cheese is bubbling. Rest 5 minutes, then top with tomato, jalapeño, and green onion. |
Pro tips
- Blend the cottage cheese first if you want a smoother egg layer.
- Don’t skip the rest — the casserole slices cleaner after 5 minutes.
- If the top browns too fast, tent loosely with foil.
- Add the fresh toppings after baking so they stay bright.
- A glass pie dish shows the layers and browns the edges well.
