Ingredients

  • 8 large eggs: Whole eggs provide protein and structure for the casserole’s rich, custard-like consistency.
  • 1 cup heavy cream: Adds creaminess and richness, helping the eggs bake into a moist, tender dish.
  • 1 cup cooked bacon, crumbled: Brings smoky, savory flavor and crunchy texture that enhances every bite.
  • 1 cup shredded cheddar cheese: Sharp cheddar adds meltiness and depth of flavor throughout the casserole.
  • 1/2 cup diced green onions: Fresh green onions add mild onion flavor and a pop of color.

Instructions

Preheat Oven

Set your oven to 350°F (175°C) to ensure it reaches the perfect temperature for even baking, allowing the casserole to cook through without drying out.

Whisk Eggs and Cream

In a large mixing bowl, thoroughly whisk together eggs, heavy cream, garlic powder, salt, and pepper. This forms a smooth custard base that will set firm yet tender once baked.

Add Bacon, Cheese, and Onions

Gently fold the crumbled bacon, shredded cheddar cheese, and diced green onions into the egg mixture. This distributes the flavors evenly so each slice has a balanced combination.

Prepare Baking Dish

Grease a 9×13-inch baking dish with butter or non-stick spray. This prevents sticking and helps with easy serving once baked.

Bake the Casserole

Pour the mixture into the prepared dish, spreading evenly. Bake for 30 to 35 minutes or until the eggs are fully set and the top shows a slight golden brown crust, indicating perfect doneness.

Cool and Serve

Allow the casserole to rest for a few minutes before slicing. This resting time helps the custard firm up and makes serving cleaner and easier.

You Must Know

  • You can customize this casserole by adding low-carb vegetables like spinach or mushrooms for extra nutrition.
  • Use thick-cut bacon for more substantial texture and flavor.
  • Make sure not to overbake, or the casserole will dry out and lose its tender texture.

Storage Tips

Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave to maintain texture and flavor.

Serving Suggestions

Pair with a fresh green salad or avocado slices for a complete keto meal. It also pairs well with coffee or a low-carb smoothie for breakfast.

Professional Tips

  • Use room temperature eggs and heavy cream to achieve a smoother custard texture.
  • Cook bacon until crisp but not burnt to keep a pleasant chewiness.
  • For best results, use sharp aged cheddar which melts beautifully and enhances flavor complexity.

What type of cheese is best?
