👩🍳 Step-by-Step: How to Make It
1. Prepare Ingredients
Preheat your oven to 375°F (190°C).
Grease your 9×13-inch dish with butter or cooking spray.
Cook the meat (bacon, sausage, or turkey) until browned and slightly crispy.
Sauté any vegetables that release water — like mushrooms or spinach — to prevent a soggy casserole.
2. Whisk the Base
In a large bowl, whisk the eggs, heavy cream, salt, pepper, and herbs.
Add half the cheese into the mixture for an even melt throughout.
3. Assemble
- Spread the sautéed veggies evenly on the bottom of your baking dish.
- Add your cooked meats on top.
- Pour the egg mixture evenly across the ingredients.
- Sprinkle the remaining cheese on top.
4. Bake
Bake uncovered for 30–35 minutes.
The top should be golden, and the center should no longer jiggle when gently shaken.
Let it rest for 10 minutes before slicing. This step ensures perfect, clean cuts without breaking the structure.
🍴 Pro Tips for Success
- Drain excess grease from the cooked meat before layering.
- Use full-fat cheese — it melts better and adds richness.
- Season each layer lightly instead of just the eggs.
- Let it cool before slicing — this prevents runny pieces.
- Reheat in the oven instead of the microwave for the best texture.
