Gluten Free Breakfast Casserole with Asparagus and Egg

An overnight egg casserole stuffed with bacon, asparagus, tomatoes, and hash browns. Easy to throw together ahead of time and impress the socks off your guests. It’s easy to make this vegetarian if you want by leaving out the bacon. I mean. If you want. I guess. Originally published December 13, 2014.

Charlotte: “Mom, your phone is wet.”
Me: “WHAT! Why is my phone wet??
“Oh, Truman dipped it in the toilet.”
“He WHAT?”
“He just dipped it Mom, it’s no big deal.”
“Char, you need to put the lid down after you go.”
Eric, from the other room: “She was using it.”
“WHAT?? Is my phone covered in pee??”
Char, nonchalantly: “Yup.”

Doesn’t he look so jolly? This is at the halfway point. If I had just run 14 miles there is no way in heck my face would look even remotely chipper. I think my face would look more like that of a wounded cow’s…or maybe a walrus in labor? I don’t know. It will never happen. Major props, Eric.

My brother Nathan ran this race too (and Sarah‘s husband Lucas! Party!). We all had brunch after the race with my family, and I served this breakfast casserole. Nathan told me after eating it how much he loved it: “I gotta tell you Karen, when you described this to me a couple days ago I thought it sounded kinda gross. But this stuff is amazing.” And he proceeded to take half the leftovers home with him.

Calling my food gross: -1. Calling my food amazing: +1. Taking leftovers: +1. Total score: +1. You’re safe Nate.

This recipe is a mashup of my 2 favorite savory breakfast dishes: Asparagus, Tomato, and Goat Cheese Quiche and Easy Breakfast Casserole with Potatoes and Ham. Both of them are crazy delicious by themselves, so I decided to throw them together. This would be a great breakfast for Christmas morning! It can be assembled the night before, or cooked right away. So you can plan ahead…or not. NICE.

Here are a few suggestions for making this casserole exactly to your liking.

Vegetarian? Just leave out the bacon.
Not a fan of asparagus? You can totally sub steamed broccoli or sauteed spinach.
If you can’t find shredded hash browns, you can use a 30 oz. package of cubed hash browns instead.
Don’t like (or don’t have) goat cheese? Try a cup of crumbled feta instead.
Try switching it up and using chopped roasted red peppers instead of tomatoes.

Troubleshooting Asparagus and Egg Casserole

How do you fix a dry breakfast casserole?

If you leave a breakfast casserole in the fridge for too long or don’t cover it well, it can definitely dry out. No judgment here, we’ve all forgotten about food in the fridge before (I do this way too often). If your breakfast casserole is already dry, you can make some hollandaise sauce (I make it in the blender, it only takes 5 minutes) to drizzle/pour on top.

To prevent it from drying out next time, make sure to cover it well and eat or freeze it within the first 3-5 days of making it.

Why is my egg casserole rubbery?

Rubbery casserole, no thank you!! Here’s what can happen: if you put uncooked vegetable or meats into a casserole, they’ll release moisture as the casserole cooks and it’ll negatively affect the texture. This recipe avoids that issue by cooking the bacon and asparagus before adding them to the casserole. While this recipe does include uncooked tomatoes, the amount of moisture they add has already been accounted for. It’s all about ratios, so if you do decide to make vegetable substitutions, make sure that you cook the veggies and use a similar amount to what is called for in the recipe.

Why is my breakfast casserole soupy?

Breakfast casserole can be soupy for a few reasons:

The recipe you’re using calls for too much liquid (eggs, milk, cream).
You put in your hash browns frozen instead of thawed.
You add uncooked veggies or meats, which will release water as they cook.
You haven’t cooked the breakfast casserole long enough.

That’s why I work so hard to test all this stuff for you guys! Kitchen failures are so depressing. This recipe includes the proper ratio of liquid to solid ingredients, calls for cooked veggies and meat and thawed hashbrowns, and has the proper baking time. No soup(-y breakfast casserole) for you :-)

What can you serve with a breakfast casserole?

Breakfast casseroles are great because they’re already a finished meal. Pour the orange juice and you’re set. But I would be the last person to stop you from going totally overboard and throwing a breakfast feast. Here are some of my favorite sweet recipes to serve with this casserole at a brunch, baby shower, or when you have guests in town.

One Hour Almond Rolls << don’t sleep on these rolls! They are like if Honey Nut Cheerios and a pan of cinnamon rolls had a beautiful baby.

The Best Scone Recipe I’ve Ever Made << perfect for adding whatever mix-ins you like.

Best Cinnamon Roll Recipe I’ve Ever Made << “It’s so fluffy I’m gonna die!!” Name that movie.

Raspberry Pull-Apart Buns with Coconut Glaze << these taste as incredible as they look.

Sour Cream Cinnamon Streusel Coffee Cake << soft, fluffy, a cinnamon-lover’s paradise.

Cinnamon Sugar Dipped Muffins << remember these classics?? They’re still going strong for a reason (and it’s probably got something to do with melted butter).

How to store overnight Asparagus Egg Bake

You can keep this finished casserole in the fridge for 3-5 days. Just warm individual slices up in the microwave when you’re ready for an easy breakfast.

How long can you keep a breakfast casserole in fridge before baking?

I recommend making this breakfast casserole no sooner than a day before. The ingredients will change texture as they sit together, which is fine for 12-24 hours, but might throw off your finished dish if you wait too long to bake it.

Can you freeze gluten free breakfast casserole?

Yes, you definitely can. It’s fine to freeze the baked casserole, BUT you can also assemble and freeze the casserole before you bake it! This is a great idea if you want to take it to someone who has a new baby, just had surgery, etc. Then they can bake it fresh. You will want to give them instructions to allow it to thaw overnight in the fridge before they bake it for the same time and temperature as usual.

Asparagus Breakfast Casserole FAQs

What can I have for breakfast if I’m gluten free?

This casserole is obviously a great place to start, but there’s so much more. If you’re gluten free, I’m sure you’ve already thought about simple basics like yogurt, fruit, eggs, and gluten free cold cereal, but sometimes you want something a little fancier.

Here are some of my favorite recipes to make for my gluten free friends!

Spinach and Bacon Frittata << like quiche without the crust.
Cheesy Ham and Broccoli Frittata << perfect for using leftover ham from a holiday!
Creamy Scrambled Eggs for a Crowd << your solution to warm, cheesy eggs for your guests.
Cheesy Overnight Breakfast Egg Casserole with Bacon << I love me a good egg casserole.
Cheesy Hashbrown Breakfast Casserole with Ham << potatoes for president.
Banana Blueberry Overnight Oats << kids love these, and you can use whatever fruit you want.
Pizza Egg Muffins << ok, these I love to make for ME. It’s a protein packed way to eat pizza for breakfast any day of the week.
Green Orange Julius Smoothie << packed with creamy orange flavor and so healthy!
Peanut Butter Banana Smoothie << here’s your excuse to drink peanut butter.

What’s the difference between strata and breakfast casserole?

Stratas are always breakfast casseroles, but not all breakfast casseroles are stratas. A strata is mainly composed of bread, eggs, a little dairy, and cheese (and maybe meat and/or veggies). Breakfast casseroles could have potatoes, biscuits, or eggs as their base ingredient, so there’s a ton of variety.

What’s the difference between breakfast casserole and frittata?

A frittata is like a crustless quiche–it’s an egg and veggie based dish that’s made in a skillet. It can be served for breakfast, lunch, or dinner. So a frittata can sometimes be considered a type of breakfast casserole, because although it’s usually made entirely on the stovetop, sometimes you can bake it (or finish it in the oven). Breakfast casseroles are baked dishes (always) and can include a huge variety of ingredients (thought they almost always include eggs).
