This low-carb bacon, egg, and spinach breakfast casserole has rescued my mundane breakfast! For several months now, I have been eating the same breakfast every day. Peanut butter toast on whole wheat bread, topped with honey is my favorite quick and easy breakfast. I love it, but I need to switch it up! I also wanted to cut back on carbs this week!

This casserole is easy to make. The key word here is LAYERS. Create the first layer by adding sauteed veggies to the bottom a baking dish.

Next, add frozen spinach.

Drizzle an egg mixture throughout.


Sprinkle cooked, crumbled bacon and shredded cheese over the top. Bake for 35 minutes.

I love casseroles! I really should make them more often. I love to combine a bunch of ingredients that pair well together, and then throw the dish in the oven and get back to life until it is finished baking. Casseroles are also a great way to sneak in nutritious veggies and high protein foods. A casserole will save you from having to prepare multiple side dishes for one meal.

So delicious! Can I make ahead, freeze (to re-heat later for a camping trip), then re-heat in oven? If so, what time/temp would you recommend? Thank you for a wonderful recipe!

This was really good! We made breakfast for dinner, and this was the recipe we chose as part of our meal. We used 9 whole eggs, and added a little minced garlic, otherwise it was made as written & it was delicious! My husband and son went back for seconds. :) Thank you!
