How To Make Vegan JUST Egg Breakfast Casserole
If you like looking at cooking pictures, here is this vegan breakfast casserole at a glance.
Step 1: In a frying pan over medium heat, add 2 tablespoon olive oil. Sauté the diced onions, bell peppers, and garlic until they soften and become aromatic.
Step 2: Add the mushrooms and cook for another 3-5 minutes. If you're using vegan meat substitute, add it to the pan and cook until browned. Set aside the veggie-meat mixture.
Step 3: In a large mixing bowl, empty both bottles of JUST Egg. Add plant-based milk, salt, and pepper. Whisk well to combine.
Step 4: Fold in vegan cheese shreds and the sautéed veggie-meat mixture into the JUST Egg mixture. Make sure everything is evenly distributed.
Step 5: After prepping your baking dish, place a layer of bread across the bottom until it's well covered, then place a layer of spinach leaves over the top.
Step 6: Pour the filling over the bread and spinach and level it with a spoon or spatula.
Step 7: Top with some sliced cherry tomatoes. Bake for 30 minutes or until the casserole is set in the middle and the edges are lightly golden.
Step 8: Remove from the oven and let it sit for 5-10 minutes to firm up. Garnish with fresh herbs before serving.
Variations
Making a breakfast casserole is about crafting a meal that suits your palate, so feel free to make it your own. Below are some variations.
- Spice It Up: Add some jalapeños, red pepper flakes, or a dash of hot sauce for a kick.
- Potato Base: Substitute the bread with a layer of thinly sliced or shredded potatoes at the bottom. Alternatively, you can use frozen hash brown patties from Trader Joe's or frozen shreds (make sure to defrost the shreds a little before layering the casserole).
- Custom Portions: Use a muffin tin to make individual servings. Adjust the cooking time accordingly, usually around 20-25 minutes.
Serving Suggestions
- Fresh Fruit: A side of fresh fruit like grapes or a combination fruit salad complements the savory flavors beautifully.
- Salad: A light, leafy green salad with a tangy vinaigrette can add a refreshing touch if you eat this for brunch. Try it with arugula and pear salad with pumpkin vinaigrette or a delicious vegan Caesar salad.
- Smoothies: A nutritious green smoothie like Homemade Vegan Mango Kale Smoothie can round out this hearty breakfast.
Top Tips
I strongly advise using parchment paper to line your baking dish. While greasing the pan is fine, it tends to make cleaning the sides a bit more challenging. With parchment paper, you'll achieve beautifully clean and neat edges and bottoms on all your pieces.
Equipment
- 9x13-inch baking dish
- Mixing bowls
- Frying pan
- Whisk or fork
- Measuring cups and spoons
- Oven
Storage
From Freshly Baked
Let the casserole cool to room temperature after it's out of the oven. Once cooled, wrap your casserole dish tightly with plastic wrap or aluminum foil. If you have a dish with a lid, even better. The goal is to prevent air from getting to the casserole, which can dry it out.
Place the wrapped or covered dish into the fridge. It should stay good for about 3-5 days.
Freezing the Casserole
Let it cool to room temperature. If you don't think you'll eat the whole thing within a few days, consider cutting the casserole into individual portions. This makes it easier to reheat just the amount you'll eat later.
Wrap each portion tightly in plastic wrap and place these pieces into a zip-top freezer bag. If you're freezing the whole thing, ensure it's in a freezer-safe dish wrapped tightly.
Reheating
To reheat, bake at 350°F (175°C) until warmed through, or use a microwave for quicker results.
If you're taking it out of the freezer, it's best to let the casserole thaw overnight in the fridge if you can. Then you can reheat it using the above fridge method.
FAQS
The vegan cheese gives a cheesy taste and texture to the casserole and adds volume. If you leave it out, substitute it with two tablespoons of nutritional yeast for a cheesy flavor and another cup of veggies for volume.
It adds moisture and makes the casserole a bit fluffier. You can omit it, but the casserole might be denser.
Yes, but make sure to thaw and drain them well to remove excess moisture.
The casserole should be set in the middle, and a toothpick or knife inserted should come out clean. Check it at 45 minutes, but my oven takes about 55 minutes to fully cook this casserole.
Just eggs are made primarily from mung bean protein, water, and various plant-based oils and seasonings. These ingredients are formulated to mimic traditional chicken eggs' taste, texture, and cooking properties, and it does it really well.

Description
A vegan "JUST Egg" breakfast casserole is a savory and hearty way to feed a crowd or meal-prep for the week ahead. You can customize it with your favorite veggies, vegan cheese, and plant-based meat substitutes.
Ingredients
Casserole
- 4-6 pieces of crusty bread slices (i.e. sourdough, French, French rye)
- 1-2 cups of spinach (30 - 60 grams)
"Egg" Filling
- 2 bottles (12 oz each) of JUST Egg
- 1 ½ cups vegan cheddar cheese shreds
- ¼ cup plant-based milk (any plant milk will work)
- Salt and pepper to taste
Vegetables and "Meat" Filling
- 2 tbsp olive oil
- 1 cup diced bell peppers (mixed colors)
- 1 cup diced onions
- 2 cloves garlic, minced
- 1 cup sliced mushrooms
- 1 cup diced vegan bacon, sausage, tempeh, or seitan
Toppings
- 1 cup cherry tomatoes, halved
- Fresh herbs for garnish (e.g., parsley, chives)
Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C). Line a 9x13-inch baking dish with parchment paper or grease with a little cooking spray.
- Saute the Vegetables: In a frying pan over medium heat, add 2 tablespoon olive oil. Sauté the diced onions, bell peppers, and garlic until they soften and become aromatic - about 5 minutes. Add the mushrooms and cook for another 3-5 minutes.
- Cook the Vegan Protein: If you're using vegan bacon, sausage, tempeh, or seitan, add it to the pan and cook until browned. Set aside the veggie-meat mixture.
- Prepare the JUST Egg Mixture: In a large mixing bowl, empty both bottles of JUST Egg. Add plant-based milk, salt, and pepper. Whisk well to combine.
- Fold in Cheese and Veggies: Fold in 1 ½ cups of vegan cheese shreds and the sautéed veggie-sausage mixture into the JUST Egg mixture. Make sure everything is evenly distributed. Set aside.
- Layer the Bread: Place the slices of bread on the base of the baking dish.
- Add the Spinach: Scatter the spinach over the top of the bread.
- Finish Assembling: Pour the mixture into the prepared baking dish, leveling it with a spatula. Sprinkle the halved cherry tomatoes over the top.
- Bake the Casserole: Bake for 45-55 minutes until the casserole is set in the middle and the edges are lightly golden. Check with a knife by piercing the center - if it comes out clean, it's ready.
- Finishing Touches: Remove from the oven, let it sit for 10-15 minutes, and garnish with fresh parsley or chives.
Notes
Kala namak, also known as black salt, adds an eggy flavor to this dish. Substitute half the salt with the black salt if you wish, or sprinkle some on top when you're ready to eat.
Nutritional information is only an estimate. Use a nutritional app like Cronometer to get information on the exact ingredients and amounts you are using.
I highly recommend using the parchment paper to get those perfectly neat edges and rectangles. When you grease the pan, you may find that the sides stick slightly.
While everyone's favorite brand of vegan bacon or sausage is different, here are a few I've tried and can recommend:
Lightlife - Smart Bacon
Sweet Earth - Benevolent Bacon
Tofurky - Smoky Maple Bacon Marinated Tempeh
Beyond Meat - Beyond Sausage
Field Roast - Grain Meat Sausages
Lightlife - Gimme Lean Sausage
