Broccoli and Three Cheese Keto Breakfast Casserole: From Prep to Plate

Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This will ensure that your casserole bakes evenly and comes out perfectly cooked.
Step 2: Prepare the Broccoli
Wash and chop the broccoli into small, bite-sized pieces. You should have about 6 cups. If you prefer, you can use frozen broccoli; just make sure it’s thawed and drained well.
Step 3: Whisk the Eggs
In a large mixing bowl, crack open 14 eggs. Use a whisk to beat them well until they are fully combined and slightly frothy.
Step 4: Add the Cheeses
To the beaten eggs, add 2 cups of grated Monterey Jack cheese, 2 cups of crumbled feta cheese, and 1/2 cup of coarsely grated Parmesan cheese. Mix well until the cheeses are evenly distributed throughout the egg mixture.
Step 5: Season It Up
Sprinkle in your desired amount of Spike seasoning or your favorite all-purpose seasoning blend. This will add a burst of flavor to your casserole. Don’t be shy—seasoning is key!
Step 6: Combine with Broccoli and Onions
Gently fold in the chopped broccoli and 1/2 cup of sliced green onions into the egg and cheese mixture. Make sure everything is well incorporated.
Step 7: Transfer to Baking Dish
Pour the mixture into a greased 9×13 inch baking dish, spreading it out evenly. Use a spatula to smooth the top for even baking.
Step 8: Bake
Place the casserole in the preheated oven and bake for 40-45 minutes, or until the eggs are set and the top is golden brown. You can test for doneness by inserting a toothpick into the center; it should come out clean.
Step 9: Cool and Serve
Once baked, remove the casserole from the oven and let it cool for about 10 minutes. This will allow it to firm up a bit, making it easier to slice. Cut into squares and serve warm. Enjoy your delicious Broccoli and Three Cheese Keto Breakfast Casserole!
