Well, I’m officially obsessed with this egg bake recipe! It was inspired by a recipe within the FASTer Way nutrition and fitness program I am a certified coach for. You get full meal plans and grocery lists every week (both regular and vegan meal plans). I love drawing on these recipes for inspiration when I’m doing my weekly meal planning!
The combination of the basil, leeks, and sweet potato in this recipe is SO good and unique! As I’ve been working on doing a better job at meal prepping my breakfasts and lunches so that I can maintain my energy throughout the day and be more efficient during my workday, I’ve been dreaming up different high-protein recipes that I’m so excited to share with you!
I love meal prepping this egg bake on a Sunday or midweek to have my breakfasts ready to go for about 3 days (I typically eat about 3 slices per breakfast!). I also love meal prepping this Tofu Scramble With Roasted Potatoes and these Gluten-Free High-Protein Breakfast Bars!

Additions & Substitutions

Step 1: In a microwave-safe bowl, add diced sweet potato and cover with water. Microwave for 5 minutes. Then carefully drain the water.

Step 2: In a large mixing bowl, whisk eggs, almond milk, salt, garlic powder, and black pepper (if using) together.

Step 3: Sprinkle leeks, basil, and microwaved sweet potato on the bottom of a greased 9×13-inch baking dish so the ingredients are spread evenly.

Step 4: Pour egg mixture over the vegetables so it’s evenly distributed. Bake in the oven at 375 degrees Fahrenheit for 25 minutes, until a toothpick comes out clean when inserted into the middle of the egg bake.

Recipe Tips & Tricks
- Meal Prep: I love meal prepping this egg dish to make my busy weeks so much easier! Prep it on a Sunday or mid-week to have breakfasts (or even serve it as a protein-filled lunch!) ready to go.
- Increase the Protein: I’m always trying to make sure I’m getting in at least 30 grams of protein per meal, if not more. If you need to increase the protein content in this recipe, here are a few ways to do it: add more eggs, add cheese or nutritional yeast, or, if you eat meat, you can add sausage, chicken sausage, or bacon to up the protein content.
What to Serve With This Egg Breakfast Casserole
- Tahini: I know it might sound strange, but tahini is SOOO good on top of this egg casserole! I love adding a big dollop on top of mine. Plus, tahini is rich in micronutrients making it a win for your taste buds and your health!
- A side of mixed berries: I love having a small handful of mixed berries on the side for the antioxidants, fiber, and because I like something sweet after having eggs!
- Purity Coffee: My favorite cup of coffee! It’s clean, organic, higher in antioxidants than regular coffee, and mold and mycotoxin free. You can use my code: SUPERMOMEATS20 to get 20% off your first order!
- If serving for dinner or lunch, serving it with a simple side salad would be yummy!
Storage & Reheating
- Fridge: Store leftovers in an airtight glass container in the fridge for 3-4 days.
