Cheesy Bacon and Spinach Egg Bake

Healthy, make-ahead breakfast recipes are one of the main reasons I’ve been able to maintain a 60+ pound weight loss for over 15 years now. If you’re new to The Lemon Bowl, be sure to read about How I Lost 59 Pounds (And Kept It Off).

Easy Egg Bake Recipe

By taking a little time at the beginning of the week to prepare a breakfast I can reheat or enjoy for several days I am much more likely to stick with my healthy eating goals (and not reach for something less healthy or skip breakfast altogether.)

Egg bakes are one of my favorite low carb, high protein breakfast recipes because they are easy to make, versatile (you can use any ingredients you have on hand!) and really delicious. After all, it doesn’t matter how healthy a recipe is – if it isn’t’ delicious you won’t eat it.

Bacon being sauteed

Speaking of delicious, this egg bake starts with crispy bacon that I fry in a deep skillet until crispy. After removing the bacon and most of the bacon grease I saute a bunch of spinach in about two tablespoons reserved bacon grease.

Next, you mix the cooked bacon and spinach with the eggs before pouring it into a prepared baking dish. Sprinkle the mixture with cheese then bake until the eggs are firm, about 30 minutes.

Frequently asked questions:

Why put vegetables in bacon grease?

Why would you want to cook vegetables in bacon grease? Bacon grease adds a ton of flavor and smokiness to anything you saute in it such as Brussels sprouts, broccoli or spinach.

How do you make fluffy eggs?

I found that adding in a little water results in fluffy, light eggs when they are baked in the oven.

How long will an egg bake last in the refrigerator?

A cooked egg casserole will last up to 7 days if stored in an air-tight container in the refrigerator.


The microwave can handle this over the oven. Place in the microwave and heat for 60 seconds to serve.

Can I Swap Out Bacon and Spinach for Other Ingredients? Absolutely! I’ve made other egg casseroles (or egg bakes) with a wide variety of ingredients.

Before serving I love to sprinkle with fresh herbs such as minced parsley or cilantro. A little heat from Sriracha or chili flakes doesn’t hurt either!
