Holidays and family get-togethers just got a little easier with this filling breakfast or brunch casserole.

If you don’t have a lot of mouths to feed when you make this meatless wonder, you can freeze or refrigerate it. This is easily reheatable, making it perfect for busy mornings.

We like to bake it on Sundays so we have a filling breakfast to enjoy for days. Another great make-ahead breakfast we do this with are my Protein Waffles.

Vegan Just Egg replaces the eggs in this recipe. It thickens nicely and topping it with a dusting of black salt at the end gives it even more of an “eggy” taste.

Another one of my favorite Just Egg recipes is this cheesy Vegan Breakfast Burrito that's filled with veggies and vegan sausage.

Ingredients and Substitutions

Onions - White or yellow onions go great here, but feel free to use any variety that you have on hand.
Peppers - Red (or any color) peppers offer a pop of flavor and color.
Mushrooms - Any kind works. My favorites in this dish are shiitake, cremini, or white mushrooms.
Vegan Ground Sausage - I use Impossible vegan sausage because it’s tasty and already ground up. If your sausage is in link-form, you can simply dice it up.
Greens - Kale or spinach are great and nutritious.
Crescent Rolls - Store-bought crescent rolls make this breakfast bake so much easier. Be sure to check the ingredients to make sure there isn’t any dairy, eggs, or lard in them. I use the Pillsbury brand.
Just Egg - Just egg serves as the egg substitute in the casserole. Look for their little yellow bottles next to the eggs or in the vegan corner of your grocery store.
Plant-based Milk - Any type of plant-based milk works.
Vegan Cheese Shreds - Use your favorite shredded vegan cheese. My favorite brands are Violife, Daiya, Follow Your Heart, and Trader Joe’s.
Seasoning - Salt, pepper, garlic powder, and paprika add a delicious dynamic while also enhancing the other flavors. We only need a pinch of each because the other ingredients are so flavorful on their own. You can certainly add more or less according to your preference.
Black Salt (kala namak) - Black salt is also called kala namak. A light dusting of this magical spice really takes these “eggs” over the top! You can omit it if you don’t have it on hand, but it’s great to add to so many recipes. Black salt can be hard to find at stores, so I usually order this one from Amazon. Kala Namak.

How to Make a Just Egg Breakfast Casserole

Here are some quick visual steps. The full recipe with exact measurements can be found on the recipe card below.

Prepare the Ingredients - Heat the oven and grease a large dish with nonstick spray, oil, or vegan butter. Make sure to coat the sides too. Cut all of the veggies into bite-sized pieces.

Sauté the Veggies and Sausage - Bring a large skillet to medium-high heat. Then sauté the onions, peppers, and mushrooms in olive oil until they start to soften. Add the sausage to the pan and cook it for a few minutes. Don’t cook it too long because it will cook some more in the oven. Finally, stir in the greens and take the pan off the heat once they have wilted.

Start the Casserole Layers - Take the crescent roll out of the refrigerator and roll it out onto the bottom of the large dish. Press to seal any holes formed by the perforated lines if your roll has them. Layer all of the sausage/veggie mixture on top of the crescent dough.

First set of process steps for egg casserole.

Add the Vegan Egg - Sprinkle most of the cheese above that layer. In a large bowl, whisk the Just Egg, plant milk, and seasoning together. Don’t add the black salt yet because we sprinkle that on top of the casserole later. Pour the egg mixture all over the casserole layers. Spread the remaining cheese over the egg mixture.

Second set of process steps for egg casserole.

Bake - Bake the casserole in the oven for about 40-50 minutes on the middle rack. Cover the dish if it looks like it's starting to burn toward the end of the bake time. Take it out when the top is starting to brown and the middle stays firm when you give the dish a little shake. Dust it with a fine layer of black salt and then let it cool for at least 10 minutes. Slice the casserole and enjoy!

Recipe Variation Ideas

Veggies: Increase the amount of vegetables and/or add more of your favorites.
Spicier: Add cayenne, red pepper flakes, or chili powder to the Just Egg mixture.
Toppings: Top your casserole slice with salsa, jalapeños, avocados, and fresh herbs.
