How to make this High Protein Veggie Egg Bake

I’ve included everything below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the Recipe card at the bottom of this post.

Step 1- Preheat your kitchen oven to 375°F and grease a standard 9x13-inch baking dish with avocado oil spray.

Step 2- Chop all the fresh vegetables into small, bite-sized pieces so they distribute evenly throughout the egg mixture.

Step 3- Whisk the whole eggs, heavy cream, salt, and black pepper together in a large mixing bowl until completely smooth.

Step 4- Layer the chopped broccoli, red bell peppers, sliced mushrooms, and fresh spinach directly into the bottom of the prepared baking dish.

Step 5- Pour the seasoned egg mixture slowly over the top of the vegetables, ensuring everything is fully submerged and evenly coated.

Step 6- Bake uncovered for approximately 35 minutes until the center is completely set and the top turns a beautiful golden brown.

Step 7- Remove the dish from the oven and let it cool for 5 minutes before slicing it into individual portions.

Common Mistakes to Avoid:

• Overbaking the Eggs: Leaving the casserole in the oven for too long will make the eggs rubbery and cause them to weep liquid.
• Skipping the Pan Grease: Forgetting to oil the baking dish thoroughly will cause the eggs to stick stubbornly to the sides.
• Chipping Veggies Too Large: Cutting your vegetables into massive chunks prevents them from softening fully during the designated baking time.

Required Equipment:

• 9x13-inch Ceramic Baking Dish: Provides even heat distribution and creates the perfect depth for uniform cooking.
• Large Balloon Whisk: Incorporates vital air into the raw egg liquid, resulting in a significantly fluffier end texture.
• Sharp Chef's Knife: Allows you to swiftly chop tough vegetables into uniform, bite-sized pieces.

Caleb’s Recipe Tips

To make this dish extra fluffy, try blending your eggs and cream in a high-speed blender for 30 seconds before pouring. Trust me, I’ve learned this the hard way after ending up with dense bakes in the past!

If your vegetables are holding too much surface moisture after washing, be sure to pat them completely dry with a paper towel. Otherwise, that excess water will release during baking and make your breakfast casserole unpleasantly soggy.

For an incredible flavor boost, try sautéing the mushrooms and peppers in a touch of grass-fed butter before adding them to the pan. This quick step caramelizes their natural sugars and takes the overall savory profile to a whole new level.

Storage Instructions

Allow your leftover casserole to cool completely to room temperature before attempting to store it. Afterward, place the individual slices into airtight glass meal prep containers and keep them in the refrigerator for up to 4 days.

If you want to freeze this dish, wrap each individual slice tightly in plastic wrap before placing them into a heavy-duty freezer bag. You can safely store them in the freezer for up to 2 months while maintaining perfect low-carb freshness. When you are ready to eat, simply thaw a slice in the refrigerator overnight and reheat it gently in the microwave for 60 seconds.
