I’ve been looking for a breakfast that’s quick, satisfying, and packed with protein, and this High Protein Egg Casserole Recipe has become my favorite. After making it a few times, I love how versatile it is—it’s great for meal prep, brunch, or a post-workout fuel-up.
The combination of fluffy eggs, crispy bacon, and melty cheese is comfort food at its finest. I enjoy prepping it ahead of time so I can grab a slice on hectic mornings.
For a different flavor twist, I sometimes pair it with a steak marinade for kabobs recipe to add a savory kick. Trust me, once you try this, it’ll be a staple in your kitchen too!

Ingredients for High Protein Egg Casserole
Here’s everything you’ll need to make this savory, high-protein dish. I’ve included tips to get the best flavor and texture.
- 8 large eggs – choose fresh eggs for a fluffier texture.
- 1 tsp. salt – enhances all the flavors without overpowering.
- 1/2 tsp. pepper – freshly cracked gives a better aroma.
- 1/2 tsp. smoked paprika – adds a subtle smoky depth.
- 1/2 tsp. garlic powder – balances the richness of cheese and bacon.
- 8 slices cooked bacon, crumbled – use high-quality bacon for crispiness.
- 3 cups bread, cubed (sourdough or French bread) – avoid frozen bread to prevent sogginess.
- 1 1/2 cups whole milk or half-and-half – richer milk makes eggs creamier.
- 2 cups shredded cheddar cheese – freshly grated melts better than pre-shredded.
Note: Serves 4 generous portions. You can also enjoy a steak marinade for salad recipe as a side to mix things up.

How to Make High Protein Egg Casserole
Preheat and Prep
Start by preheating your oven to 350°F (175°C). Grease the bottom of your baking dish with butter to prevent sticking and add flavor.
Cook Bacon and Cube Bread
Cook bacon until crispy, then crumble it. Cube your bread into 1-inch pieces and spread evenly at the bottom of the dish for perfect texture.
Mix Eggs and Milk
In a large mixing bowl, whisk together eggs, milk, salt, pepper, smoked paprika, and garlic powder until smooth. This creates a creamy base for your casserole.
Assemble the Casserole
Layer the crumbled bacon over the bread, sprinkle half the cheese on top, then pour the egg mixture evenly. Finish with the remaining cheese for a golden topping.
Bake and Serve
Bake for 40-45 minutes until the eggs are set and the top is golden brown. Let it cool for 5 minutes before slicing to serve.
Additional Tips for Making this Recipe Better
- I like to use day-old bread because it soaks up the egg mixture perfectly without turning mushy.
- For extra flavor, I sometimes add a pinch of cayenne or hot sauce into the egg mixture.
- I always let it rest a few minutes after baking; it slices cleaner and holds its shape better.
- I use a mix of cheeses like cheddar and mozzarella for extra gooeyness.
How to Serve High Protein Egg Casserole
I usually slice it into squares and serve warm. Garnish with fresh herbs like parsley or chives for color. It pairs well with a light side salad or fresh fruit for a balanced breakfast. For brunch, I like to add a drizzle of hot sauce—it gives the cheesy, smoky flavors a tasty kick.
