Vegan Breakfast Casserole

When I was little, my mom cooked a breakfast casserole when serving a large group of people. Because everything was pre-cooked and all in one pan, my sister and I called it her lazy breakfast casserole. Since then, of course, my sister and I repeated the same breakfast casserole recipe for our own families. Today, I decided to make a vegan breakfast casserole with the same intention in mind; feeding a large crew of hungry vegans.

My veganized version of vegan breakfast casserole packs in more vegetables than tofu with a savory and delicious taste. For that reason, I chose Meditteranean flavors. But, as I cooked, I realized the possibilities of creating various types of vegan breakfast casseroles that taste entirely different. 

Vegan breakfast casserole variations

My partially Greek family loves Mediterranean flavors, so I chose those flavors for my vegan breakfast casserole. For instance, I used sun-dried tomatoes, kalamata olives, portobello mushrooms, zucchini, onion, garlic, spinach, and red peppers.

Although these flavors created an incredible breakfast casserole, I started thinking about constructing different vegan breakfast casserole recipes the next time.

For example, use spicy vegan sausage, black beans, red onions, jalapenos, Pico de Gallo, avocado, and cilantro for a Mexican huevos rancheros casserole. 

Or, make one with Vegan Coconut Bacon, tomatoes, green onions for a Denver vegan breakfast casserole recipe.

Regardless of the ingredients, this vegan breakfast casserole recipe makes it easy to incorporate different flavors inside this delicious breakfast casserole recipe. 

How to make a vegan breakfast casserole 

Like my mom's non-vegan recipe, everything goes together in one pan for a breakfast entree for 12 people.

Even without 12 people, this breakfast casserole made ahead of time supplies a whole week of breakfasts.

Even though I used a 9 X 12 glass pyrex pan, you can split the recipe in half and make it in an 8 X 8 pan, or even in large muffin pans to freeze and reheat when you want. 

First, chop all the veggies beforehand and prepare the tofu batter. The trick to the tofu batter trick is to drain the extra firm tofu without pressing it. 

Then, cut it into cubes, put it in the food processor with brown-rice flour, nutritional yeast, seasonings, and a little soy sauce. 

Next, blend on high until smooth and creamy with a thick texture. Set aside while preparing the vegetable. 

Now, prepare the vegetables by sauteing in a large non-stick skillet. If the vegetables stick to the pan, pour a small amount of vegetable broth or water. 

Once the batter is blended, saute my onions, garlic, and mushrooms until translucent and brown. I always use a little vegetable broth to make sure my veggies don't stick. Then, I add red peppers and zucchini. 

For example, I use sun-dried tomatoes without oil to avoid using oil. Because the sun-dried tomatoes need to be hydrated, chop them and sautee them with the vegetables for added moisture. Then, add kalamata olives and zucchini.

Fold the sauteed vegetables into the prepared tofu batter

Add the spinach last when the vegetables are almost done because it wilts quickly. For the final step, fold the veggies into the batter gently.

Make ahead and bake 

To cook the vegan breakfast casserole, pour the batter into a 9 X13 inch pan. Since the batter is a little thick, you need to spread it evenly in the pan. 

Preheated to 350 degrees, and then bake the casserole and bake it uncovered for one hour. I suggest putting it on the top rack for 30 minutes before the casserole is done baking.

Another helpful hint is to allow the casserole to set up for about 15-20 minutes before cutting it to stay together.

Ingredients

  

1x2x3x

Tofu Batter

• ▢ 28 ounces Extra Firm Tofu
• ▢ 2 cups brown rice flour or flour of choice
• ▢ ½ cup nutritional yeast
• ▢ 1 Tablespoon Tamari or soy sauce
• ▢ 3 Tablespoons unsweetened unflavored almond milk or plant-milk of choice
• ▢ 2 teaspoon garlic powder
• ▢ 2 teaspoons onion powder
• ▢ 1 teaspoon sea salt
• ▢ 2 teaspoons fresh ground pepper
• ▢ 2 teaspoons tumeric

Vegetables

• ▢ 1 yellow onion diced
• ▢ 16 portobello mushrooms or mushrooms of choice, sliced thin
• ▢ 2 cloves garlic minced
• ▢ 1 zucchini diced
• ▢ 1 red pepper diced
• ▢ 3 cups organic baby spinach chopped
• ▢ 2 teaspoons fresh rosemary chopped
• ▢ ½ cup sun-dried tomatoes chopped
• ▢ ½ cup kalamata olives diced

Instructions

 

TOFU MIXTURE

• Drain, but do not press tofu
• Cut into cubes
• Place cubes in a large food processor cup (I have an 11 cup food processor)
• Add flour, nutritional yeast, soy sauce, plant milk, and seasonings.
• Blend until smooth
• Set aside

VEGETABLES

• In a non-stick saute pan, saute onion and garlic until onions are translucent.
• Add mushrooms and sautee; add a little vegetable broth to avoid sticking.
• Once mushrooms are brown, add red pepper, sun-dried tomatoes, and kalamata olives.
• Saute a few more minutes
• Add zucchini (which gives off a lot of water); this helps loosen the sun-dried tomatoes.
• Add a little more vegetable broth, and then add spinach last.
• The spinach will wilt quickly. Remove from heat.

FOLD VEGETABLES INTO BATTER/BAKE

• Pre-heat oven to 350 degrees
• Transfer batter to a large bowl, scraping down the sides.
• Gently fold in sauteed vegetables until mixed
• Pour batter into a 9 X 13-inch pan
• Place in the oven uncovered for 1 hour
• If using vegan cheese, add 30 minutes before removing from the oven
• Remove from oven and let sit for 15-20 minutes to set up before serving
