Easy Crab and Spinach Egg Casserole

Today we’re going to take all the flavors of summer and create an amazing EASY CRAB AND SPINACH EGG CASSEROLE! This is a bit different than traditional breakfast bakes and dishes like that, but you can enjoy it for any meal of the day! We give it a nice creamy egg base that we know you will love just as much as we do!

This one looks like a lot, but I promise you this is a labor of love and it is totally worth it! Because this dish is cooked, you at least don’t have to worry about beating your eggs and half-and-half until they thicken because that will conveniently happen during the cooking process.

Whole food, simple ingredients really shine in this recipe. All of our quiche type favorites, without the crust and carbs!

  • Breadcrumbs, salt, pepper and nutmeg– our simple but effective spice combo.
  • Pepper Jack cheese– this gives a ton of flavor.
  • Onion, sweet pepper and mushrooms– a great way to get our veggies. We saute them in Butter.

This casserole is gorgeous right out of the oven. It’s like a quiche, but even better! This comes together and cooks up perfectly, weighing in with around 8 carbs and 10 grams of protein per serving. I can’t think of a better way to get all this and your veggies all in one place!

Substitutions & Variations

With this recipe, I can think of a few customizations to help you get cooking.

Crab – We love the canned Bumblebee crab for many reasons, but you can certainly use fresh, if it is available. Just make sure you get 12 ounces of lump crab meat.
Cheese – While we prefer Pepper Jack cheese, go with your heart on the cheese and use your favorite! Cheddar, Swiss, whatever you like the best!
Nutmeg – Nutmeg really adds something special to the dish, but we understand that some people do not like it, so feel free to leave it out, if you need to.

Make Ahead and Storage Tips

Make ahead of time:  You an prepare this casserole the night before if you need to. Just cover with plastic wrap and pop it in the fridge! Reheat the next day and enjoy.
Storage: This will keep in the fridge for a 3 or 4 days. Just make sure it’s in an airtight container or covered with plastic wrap. We don’t recommend freezing this, since the eggs and cream don’t do well in the freezer.

Notes

*PRO TIP*- heavy egg dishes should have an internal temperature the same as cooked chicken. To be sure they are done, use a meat thermometer and if the center reads 160-165°, the dish is done!

🍴 PRO TIP!

Even if you know someone who isn’t keen on nutmeg, you use so little in this casserole that all they will notice is that the vegetables in this are sweeter and warmer and the flavors are enhanced. Nutmeg is one of flavor’s best friends, just like salt! Lift your flavors up on a pedestal with nutmeg!
