How to make a keto egg bake
This is a no-fuss recipe that bakes in the oven for a while, leaving you to make the rest of the meal and get everyone ready for the day ahead.
Step 1: Add the olive oil to a pan over medium heat. Once the oil has heated, add the onion, garlic, and spinach and cook for 5 minutes until the spinach has reduced. Set aside.
Step 2: In a large mixing bowl, whisk together the eggs, half-and-half, and salt and pepper. Stir in the shredded mozzarella and feta cheese. Leave aside some of the cheese to sprinkle on top.
Step 3: Add the cooked spinach and egg mixture to an 8×8 inch (20×20 cm) casserole dish and mix well. Sprinkle over the rest of the cheese.
Step 4: Bake the keto egg bake for 40 – 50 minutes until the middle is firm and a toothpick inserted comes out clean. Remove from the oven and allow the egg bake to cool for 10 minutes before slicing and serving.
Adding more veggies or protein
You can add in a ton of extra vegetables to this dish to make it even healthier or add more protein by including cooked meats. Here are some great vegetable and protein options to add to this dish:
- Bell peppers
- Cooked sausage
- Grilled bacon
- Crumbled tofu for a vegetarian option

Making it ahead of time
If you’re super busy and don’t have time to put this egg bake together in the morning, you can prepare it the day before or even make it ahead for the week.
If you want to eat the keto egg bake within 12 hours (perfect for the next morning) then assemble the egg bake but don’t bake it just yet. Cover with plastic wrap and refrigerate. Then you can pop it into the oven for 40 – 50 minutes the next morning and breakfast is served!
Storing and freezing
It’s also a breeze to prepare this egg bake ahead for the week and freeze it. It comes out perfectly done after being frozen and cooked.
To freeze your egg bake, prepare as usual but don’t bake it. Rather, cover with plastic wrap and freeze. When you want to make the egg bake, remove from the freezer and allow to thaw completely. Then bake as normal.
You can store any leftover egg bake in an airtight container in the refrigerator for up to 5 days. It can easily be heated in the microwave or oven for a quick breakfast and lunch option.
