• Large mixing bowl
• Whisk
• Cutting board and knife
• 2-quart baking dish (approximately 9×13 inches)
• Measuring cups and spoons

Instructions

Follow these simple steps to prepare your amazing high protein egg casserole breakfast:

1. Step 1: Preheat your oven to 350°F (175°C). Lightly coat a 2-quart baking dish with non-stick cooking spray to prevent sticking.
2. Step 2: If using optional vegetables, chop them into small, uniform pieces. If your chosen protein isn’t already cooked, cook or brown it now according to package directions. Drain any excess fat.
3. Step 3: In a large mixing bowl, whisk the six large whole eggs until they are well combined and slightly frothy. Stir in the plain Greek yogurt until smooth.
4. Step 4: Add the shredded cheese, your cooked protein, and any chopped optional vegetables like spinach, onion, and bell peppers to the egg mixture.
5. Step 5: Season the mixture generously with salt and black pepper to your taste. Remember, these seasonings are key to a flavorful high protein egg casserole breakfast.
6. Step 6: Pour the entire combined mixture evenly into your prepared baking dish. Spread it out so all ingredients are distributed.
7. Step 7: If you have any extra cheese, fresh herbs, or other desired toppings, sprinkle them evenly over the casserole mixture at this stage.
8. Step 8: Carefully place the baking dish into the preheated oven. Bake for approximately 45-50 minutes.
9. Step 9: The casserole is done when the edges are golden brown and the center is set with minimal jiggle. An inserted knife should come out clean.
10. Step 10: Remove the casserole from the oven and let it rest for 5-10 minutes before slicing and serving. This resting period helps it set further.

Pro Tips for Success

Achieve the perfect texture every time by ensuring your vegetables are chopped uniformly and any raw meat is fully cooked before mixing. Prevent your casserole from sticking by generously coating your baking dish with non-stick spray or butter. Boost flavor significantly by lightly sautéing your onions or bell peppers before adding them to the egg mixture. For busy mornings, assemble this high protein egg casserole breakfast the night before, cover, refrigerate, and then bake in the morning. If your eggs are runny, bake longer; if they’re rubbery, you might have overbaked or used too high a temperature.

Serving Suggestions, Storage & Variations
