How to Make Vegetarian Breakfast Casserole

Now that you have all your ingredients ready, it’s time to immerse yourself in the fun part—making this delicious Vegetarian Breakfast Casserole.
First things first, grab your trusty baking dish or crock pot and grease the inside with a little cooking spray or oil. This step is key because nobody wants to end up with a casserole that’s stuck to the pan like glue. Trust me, I’ve been there, and it’s not pretty.
Next, let’s layer everything. Start with the 14-ounce package of soy sausage. Crumble it into the bottom of your greased dish. Then, sprinkle in the chopped 1 medium white onion, followed by the sliced summer squash and 2 sliced carrots.
Layer on the chopped 1 medium bell pepper (red or green—your pick) and the 4 ounces of undrained diced green chilies. Now, here’s where it gets cheesy—in the best way. Sprinkle 2 cups of fat-free mozzarella cheese over the top.
Repeat these layers until you’ve used up all your ingredients. It’s like building a veggie tower of deliciousness, and honestly, who doesn’t love a good tower?
Once everything is layered beautifully, pour 1/2 cup of water over it all. This will help keep things moist while cooking. In a separate bowl, mix 2 cups of egg substitute until it’s nice and combined.
Then, slowly pour this egg mixture over your layered casserole. Cover it up with a lid or some foil, and now comes the waiting game. Cook it on low for 7-8 hours. Yes, I know that feels like an eternity, but envision this: you’re sipping your coffee, relaxing, and letting the magic happen in your kitchen.
And when it’s finally done, you’ll have a warm, hearty breakfast ready to serve. So, resist the urge to peek too often—patience is key here.
Vegetarian Breakfast Casserole Substitutions & Variations
While the traditional Vegetarian Breakfast Casserole is a hit on its own, there’s plenty of room for creativity with substitutions and variations that can cater to your taste preferences.
You can swap soy sausage for tempeh or mushrooms for a different texture. If you prefer a kick, try adding jalapeños or spicy cheese.
For veggies, mix in spinach, zucchini, or even sweet potatoes. I often switch up the cheese, using cheddar or pepper jack for added flavor.
Don’t forget herbs! Fresh basil or cilantro can elevate your casserole.
Experimenting keeps it exciting, so feel free to make it your own!
Additional Tips & Notes
To guarantee your Vegetarian Breakfast Casserole turns out perfectly, I recommend prepping your ingredients the night before. It saves time in the morning and ensures everything’s ready to go.
Also, feel free to customize the veggies based on what you have on hand; it’s a great way to reduce waste! If you prefer a creamier texture, you can mix in a bit of cream cheese with the egg substitute.
Finally, don’t skip the toppings! A dollop of sour cream and a splash of hot sauce can elevate the dish. Enjoy experimenting and make it your own!
