Recommended Ingredients & Equipment

Even though this casserole is made with a handful of easy ingredients, the flavors are out-of-this-world all thanks to the fresh veggies which can easily be found in the produce section at most well-stocked grocery stores.

Here is everything you need.

Ingredient Notes

• Onion: White onion is fragrant and gives this casserole a flavorful savoriness that pairs well with the other fresh veggies. Feel free to use red onion if you would like a more rich flavor.
• Broccoli: I recommend fresh broccoli but frozen broccoli florets can work in a pinch.
• Mushrooms: I like to use sliced button mushrooms because they are neutral in flavor and absorb the ingredients they are cooked with. Of course, feel free to use any kind of mushroom like cremini, porchini, shiitake, baby bella, etc.
• Chickpea Flour: Also known as garbanzo or gram flour, cickpea flour is a great gluten-free, nutrient-dense opion for this breakfast casserole. Chickpea flour has the perfect amount of fat, protein, moisture, and stucture that allows this casserole to be totally delicious. You can find chickpea flour in grocery stores near the flours in the gluten-free sections.

Recommended Equipment

For this vegan breakfast casserole, you will need a sharp knife, wooden cutting board, kitchen utensils with measuring cups and spoons, large mixing bowl, and a 9x7-inch baking dish. << affiliate links

Step-by-Step Instructions

Step One – Chop the Vegetables

First, preheat the oven to 350 degrees Fahrenheit. Grease a 9x7-inch baking dish with oil or vegan butter and set aside.

Next, chop the onion and broccoli. Slice the mushrooms and cherry tomatoes, then add the veggies to the prepared baking dish, evenly spreading out the veggies so that they coat the bottom of the baking dish.

Step Two – Mix the Chickpea Flour

In a bowl, add 2 cups of chickpea flour, 2 ½ cups of water, Italian seasoning, salt, and pepper. Mix the ingredients with a whisk until smooth and fully combined.

Pro Tip: Do not taste this mixture to adjust for flavors. Chickpea flour has a pungent taste when raw. But don't worry! The taste completely disappears when baked.

Step Three – Assemble and Bake

Pour the chickpea mixture over the tops of the vegetables in the baking dish. The veggies will rise to the top and that's okay! (See photo above)

Bake the casserole in the preheated oven for 35-45 minutes until the edges are golden. The center casserole will have a slight jiggle to it. It will continue to set as it cools.

Allow the casserole to cool at room temperature for 10 to 15 minutes before serving.

Serving and Storing

Serving – Serve this breakfast casserole warm with vegan parmesan cheese or mozzarella for extra flavors. Pair this casserole along with your favorite vegan breakfast sides for a full vegan brunch.

Storing – Store the leftover casserole in an airtight container in the refrigerator for four days. When ready to eat the leftovers, warm the casserole in the microwave for a minute or two or in an oven at 325°F for 15 minutes, until heated all the way through.
