As soon as we finished making our oven baked JUST Egg quiche we knew we wanted to create a vegan frittata recipe.
Why This Recipe Works
It's perfect for any meal from brunch to dinner; and of course breakfast.
It’s easy and versatile. Lots of variations with vegetable selection, vegan cheeses and seasonings.
A frittata is basically a flat omelet. It originated in Italy. Our egg-free frittata is made with Just Egg - a plant-based egg substitute. With broccoli, vegan cheese, onions and peppers for our mix ins.
Sides that complement a Just Egg frittata include vegan bacon, hash browns and gluten-free vegan biscuit.
Be sure to read our full guide about what vegan eggs are and if they are healthier for you than regular eggs.
Ingredients

JUST Egg - an egg substitute made from mung beans.
Broccoli - We use frozen but you can use fresh or frozen broccoli for this recipe. If you use frozen broccoli, just make sure that it’s thawed and drained before you add it to the frittata.
Vegan Cheese
Mushrooms
See recipe card for full quantities.
Instructions
Step 1: Preheat oven to 375°F.
Step 2: We use frozen broccoli for this recipe to keep it simple and quick. Be sure that it’s thawed and drained before. If using fresh broccoli; rinse, trim stalks and chop. You’ll need to sauté longer than the frozen broccoli which is already partially cooked.
Step 3: Rinse red bell pepper and diced pepper and onions. Set aside.
Step 4: Heat 2 tablespoons olive oil in a large (10 inch oven-safe skillet) over medium-high heat. Add the onion and peppers to the skillet and cook, stirring until onions are softening, approximately 3 minutes.


Step 5: Reduce to medium heat. Add broccoli and mushrooms to mixture. Season with a pinch of salt and pepper. Continue to cook the vegetables for another 6 minutes
Reduce heat to low.


Step 6: Add pieces of vegan butter all around the pan to distribute the butter across the bottom of the skillet. Spread the vegetables into an even layer, using a spatula to flatten. If your skillet isn’t oven-safe, transfer the mixture to your prepared baking dish.
Step 7: Shake the Just egg mixture well and pour into the skillet directly over the vegetables, tilting the pan to make sure the eggs have settled evenly.
Sprinkle the cheese on top.


Step 8: Transfer skillet to the oven and bake, approximately 25 to 35 minutes until firm in the center. Remove from oven.
Step 9: Use a silicone spatula to carefully jiggle the frittata from the sides.
Step 10: Allow to cool for 5 minutes before serving. Enjoy!

Equipment
10" inch oven safe pan (we used a stainless steel, oven-safe skillet. Because it’s not nonstick you have to add oil to grease the pan to prevent sticking). You can also use a baking dish or cast iron skillet.
Silicone Spatula
Oven Mittens or Dish Towel
Mixing Bowl
Tip
Remember to use oven safe mitts/dish towel when removing frittata from the oven. This is to prevent burning your hand
Storage
- To Store. Cool before refrigerating. Store in airtight container. Store in refrigerator for up to 4 days.
- To Freeze. Cool before freezing then wrap the frittata tightly in plastic wrap. Freeze frittata in an airtight freezer-safe storage bag for up to 3 months. Let thaw overnight in the refrigerator before reheating.

Just made this for a birthday brunch for the love of my life. My need to use the Just Eggs is due to an egg allergy. So I have to admit, did not need to use the vegan butter and cheese. The frittata was wonderful. Since finding this product, I have been able to once again enjoy breakfast food.

Was super surprised at how good this came out. I’ve tried other egg replacers but this was just like what I remember eggs being like.

Can I replace broccoli for spinach?
Nija Clark
Hi EJ,
Great question. Yes, you can just blanch the broccoli until just tender it will finish cooking in the frittata. To blanch, heat a large pot of salted water to a boil. Cut broccoli into small florets. Add broccoli to boiling water and cook until slightly tender, 1–2 min. Drain and rinse with cold water to stop broccoli from over cooking. Add to frittata. If you give it a try, let us know!

Can i freeze these and eat them for breakfast?
Nija Clark
Hi Sharon,
Sure can. Freeze the frittata in an airtight freezer-safe storage bag for up to 3 months. Let thaw overnight in the refrigerator before reheating.
Thanks for asking.
