- Diced bell peppers: Half a cup of colorful bell peppers lends sweetness and a refreshing crunch.

Instructions
- Preheat the oven
-
Set your oven to 350°F (175°C) to ensure it’s fully warmed up when the casserole is ready to bake, allowing for even cooking and a golden top.
- Whisk together eggs and cream
-
In a large bowl, thoroughly whisk the eggs with heavy cream, garlic powder, salt, and pepper. This creates a smooth, seasoned custard that forms the casserole’s base and gives it a tender texture.
- Incorporate vegetables and cheese
-
Stir in chopped spinach, diced bell peppers, onion, and shredded cheese gently but evenly. Mixing these ingredients throughout ensures each slice is bursting with flavor and nutrients.
- Pour into greased baking dish
-
Lightly grease a 9×13-inch baking dish with butter or non-stick spray. Pour the egg mixture evenly into the dish to help it cook uniformly and prevent sticking.
- Bake until set and golden
-
Place the dish in the preheated oven and bake for 30-35 minutes. The casserole is done when the eggs are fully set and the top shows a beautiful golden color, indicating perfect doneness and enhanced flavor.
- Cool and serve
-
Allow the casserole to cool slightly before slicing. Cooling helps it firm up, making it easier to cut clean slices and enhancing the texture when served warm.
- Use fresh, high-quality ingredients for the best taste and texture.
- This casserole can be customized with your favorite keto-friendly vegetables or spices.
- Make sure not to overbake to avoid a dry texture; the eggs should be just set.
Storage Tips
Store any leftovers in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or oven until warmed through, preserving moisture and flavor.
Serving Suggestions
Enjoy slices on their own or paired with a side of avocado, a fresh green salad, or crispy bacon to create a complete keto breakfast feast. This casserole also pairs well with low-carb hot sauce or sour cream for added zest.
- For an even richer flavor, try mixing in cream cheese or goat cheese.
- Use a food processor to chop vegetables finely for a smoother texture.
- Rotate the dish halfway through baking for even cooking and browning.
