Why You'll Love This Easy Breakfast Casserole

You might have thought your days of enjoying a savory breakfast casserole, (heavy on the eggs, meat, and dairy) were long gone. Well, now you can still enjoy that hearty brunch classic and get the added benefits of it being healthy and nutritious! Whether you're feeding a crowd during the holidays or want something you can meal prep and make ahead of time to pop in the freezer for a rushed morning reheat, this casserole has your back! It's 100%:

What's In This Healthy Breakfast Casserole?

ingredients for vegan breakfast casserole

  • Potato Hashbrowns: The bottom layer of this casserole is the hashbrowns! You can use frozen and defrosted shredded hashbrowns or a plain pre-shredded refrigerated variety like Simply Potatoes (which is what I used). Of course, if you're feeling ambitious, you can always shred potatoes and make them from scratch!
  • Vegetables: You can mix and match your veggies for this casserole! I chose some classic breakfast veggies, including red bell pepper, baby portabello mushrooms, tomato (any kind, I used Roma), onion, garlic, and spinach! I used frozen spinach and just made sure it was broken up into small chunks. You can you fresh too! Other veggies you might like would be zucchini, broccoli, kale, other types of peppers, carrots, corn, etc.
  • Vegan Cheddar: Now you don't "have" to use a packaged vegan cheddar if you want this meatless casserole to be 100% whole food. You can season your egg mixture with more nutritional yeast to make up for the lack of cheddar. Since I know you'll want some "cheese", pick your favorite brand (So Delicious, Daiya, Violife, Good Planet), and load it on in the middle of the casserole and on top! You can even pick a mixed Mexican variety or pepper jack if you want! Alternatively, you can also skip the cheese and add homemade nacho cheese sauce to the top of the casserole after baking!
  • Chickpea Egg: The STAR of the show! Don't worry, there is nothing fancy here and you definitely don't need tofu or Just Egg. This chickpea egg is a simple mixture of chickpea flour, water (or non-dairy milk), plus seasonings which include turmeric, pepper, and nutritional yeast! You only need a small amount of nutritional yeast since you're using vegan cheddar, but if you don't use the cheddar, you can up the amount of nutritional yeast to get a more cheesy flavor. You can also add a few shakes of smoked paprika for a "smokey, meaty" flavor or some Kala Namak, which is Himalayan Black Salt, for a sulfur "eggy" flavor!

Can I Add Vegetarian Meat To My Casserole?

If you DO what to add some meatless vegetarian meat to your casserole, you can! You can crumble up some vegan eggplant bacon, coconut bacon, or even use some Beyond Beef Crumbles and just mix these right in with the veggie layer which you'll see below!

How To Make The Vegan Breakfast Casserole

process steps for making vegan breakfast casserole

  1. First, you'll need a large 9x13 casserole dish, before you layer in your hashbrowns.
  2. Then add your chopped veggies and half the vegan cheese.
  3. In a bowl, you'll mix up your chickpea egg. The amount of liquid you need will vary depending on your brand of chickpea flour, I've found. It should be thick, but still runny.
  4. Pour the egg mixture over the casserole so everything is covered.
  5. Top the casserole with the other half of vegan cheddar and green onion if you want before popping it in the oven!
  6. Bake for just about 30 minutes, remove and let it cool a bit before slicing it up!

Make-Ahead and Freezing Instructions

  • Make-Ahead & Meal Prep: To make this veggie-packed breakfast casserole ahead of time, you can chop all your veggies, whisk together the eggless chickpea egg, and layer all the components in your baking dish the night before and store it in the fridge, ready to bake the next morning. This is great if you're having guests over for the holidays and want to serve them a warm meal the next day! You can also meal prep this for yourself to have in the fridge for the week! Bake the casserole, let it cool, and store, covered, in the fridge for up to 7 days! Simply reheat in the microwave or the oven at 350°F until warmed through.
  • Freeze: You can freeze the baked casserole, tightly wrapped and covered with foil for 4-5 months. Thaw in the fridge and reheat in the oven at 350°F until warmed through. You can also pre-slice the casserole into individual portions before freezing for a quicker and easier thawing and reheating process.

Serving Suggestions

You really don't need anything else with this super hearty vegan breakfast, but a few sides and toppings never hurt! Pair your casserole serving with a side of fresh seasonal fruits, gluten-free toast with dairy-free butter or jam, homemade biscuits and gravy, mini cornbread muffins, eggplant bacon, or a crisp cucumber salad!

You can top the casserole with some hot sauce, ketchup, bbq sauce, a sprinkle of vegan parmesan, fresh chopped scallions, or fresh herbs like parsley or cilantro!

  • Author: Rebecca Pytell
  • Prep Time: 10 Minutes
  • Cook Time: 30 Minutes
  • Total Time: 40 minutes
  • Yield: 12 Servings 1x
  • Category: Breakfast
  • Method: Bake
  • Cuisine: American

Ingredients

Scale
  • 20 oz Shredded Potato Hashbrowns (refrigerated or frozen and defrosted)
  • 1 Cup Chopped Mushrooms (baby portobello or white button)
  • 1 Cup Chopped Vidalia Onion
  • 1 Cup Chopped Red Bell Pepper (or any color)
  • 1 Cup Chopped Tomatoes (any kind)
  • 1 Cup Chopped Spinach (frozen or fresh)
  • 1 Tsp Minced Garlic
  • 2 Cups Vegan Cheddar Cheese Shreds (divided)
  • Chopped Scallions (to garnish)

Chickpea Egg:

  • 2 ½ Cups Chickpea Flour
  • 4 Cups Water*
  • 1-2 TB Nutritional Yeast (optional)
  • 1 Tsp Turmeric
  • ½ Tsp Black Pepper

Instructions

  1. Preheat the oven to 425°F.
  2. Chop and prepare your vegetables and set them aside.
  3. In a large mixing bowl, mix together your chickpea egg. The amount of liquid you need will vary so continue adding liquid until it is runny but still a bit thick. Adjust seasonings to taste.
  4. In a greased large 9x13 casserole dish, layer in the hashbrowns.
  5. Then add the chopped veggies and 1 cup of the vegan cheddar cheese shreds.
  6. Now, Pour the chickpea egg mixture over the casserole and spread it out so everything is covered.
  7. Top the casserole with the rest of the vegan cheddar and some sliced green scallions, if desired*.
  8. Bake for about 30 minutes, remove and let it cool slightly before slicing into squares.

Notes

  • When making the chickpea egg, you can use water or plain unsweetened non-dairy milk. You may need more than 4 cups of liquid. You want the mixture to be runny enough that it covers the entire casserole.
  • Feel free to swap out the veggies with anything you'd like! Same goes for seasonings. See details and suggestions in the ingredient section of the blog post.
  • If you add the scallions prior to baking, they'll get crispy! I love that, but you can also add them just to serve if you don't want them browned.
  • To store the baked casserole, allow it to cool before covering and storing in the fridge for up to 7 days. Freeze for 4-5 months. Reheat leftovers in the microwave or oven as needed.

While I may not personally be a huge fan of savory breakfasts, (give me the cereal and pancakes please!), this eggless breakfast casserole is a must-have for brunch, even "breakfast for dinner", in my opinion! When you need a hearty vegetarian breakfast for a crowd...this.is.it!

So tell me:
