Gluten Free Breakfast Casserole with a black spatula for serving.

This gluten free breakfast casserole with veggies & Gruyere cheese is some of the yummiest, healthy comfort food you’ll ever eat. Bold statement I know, but true!

You can call this gluten free breakfast casserole a “strata” too.

I did a quick Google search to see what kind of healthy comfort food is trending & stumbled upon “Gluten Free Breakfast Casserole”.

So, that’s what I’m calling this recipe. But you might also know it as a “strata”, which is a layered casserole dish featuring bread, eggs, and cheese.

Besides those main ingredients, you can add anything you want to make your strata absolutely delicious.

How to make a gluten free breakfast casserole…

  1. Cut bread into cubes & place it in a greased 13×9 baking dish. I used up all the bits and bobs of gluten free bread in my fridge-5 slices of Cook’s Sourdough Bread, 1 Happy Campers Gluten Free Bun, & 1 Canyon Bakehouse Bagel. Use any bread, gluten free or regular, you have on hand.
  2. Saute veggies & fresh herbs, and layer them on top of the bread cubes. For my gluten free breakfast casserole, I sauted leeks, baby spinach, and fresh oregano, but you can make this with whatever veggies you have at home. Suggestions: artichoke hearts, arugula, basil, bell peppers, broccoli, cilantro, dill, mushrooms, onions, sage, Swiss chard, thyme, tomatoes, zucchini & so many more!
  3. Make your egg & milk mixture, and grate some cheese. Pour the egg mixture on top of the bread & veggies. Press the bread down to coat it in the egg mixture, then top with grated cheese.
  4. Bake in a 350 F oven for ~ 40 minutes, or until nice and golden brown with bubbly cheese. Eat!

Low FODMAP Option

This breakfast casserole is gluten free and vegetarian. You can easily make it low FODMAP by using the dark green portion of the leeks and lactose free or low FODMAP plant based milk.

Tip! You can prep this gluten free breakfast casserole ahead of time. Make it the night before so the bread can soak up all the egg mixture. Then bake it the next morning. Leftovers freeze well too!

Make it a meal!
