Veggie Egg Muffins
I have been wanting to develop a veggie egg muffin recipe, and alas! The time has come. Think delicious eggs… sautéed onions, bell pepper, mushrooms and spinach… cheese… is your mouth watering yet?! Veggie egg muffins pack protein, fiber and essential nutrients into one delicious handful.
Meal Prep Veggie Egg Muffins
These egg muffins are an easy meal prep recipe! Mornings can be stressful, so you can make them in advance, refrigerate and pop them in the microwave for about 30 seconds for a “morning-rush” meal! To warm up from frozen (yes these freeze well! – just be sure they cool completely before freezing), microwave for about a minute and a half.

If you want them straight from the oven, then simply make the recipe the night before up through putting the mix in the muffin tins, refrigerate overnight and bake in the morning while you get dressed!
Egg Muffin Breakfast Sandwich
My favorite variation of these egg muffins are to turn them into a breakfast sandwich! I like to throw a whole wheat English muffin and slice of cheese in the toaster oven, add a slice of pan-fried Canadian bacon (just medium heat for about a minute and a half each side), squish it all together and then – immediate, magical heart eyes happen. It is the best breakfast at home situation you’ve had since your mom made breakfast for you. Want to get even more festive? Add some mashed avocado and throw in some more spinach. Maybe even some sliced tomato. The world is your egg muffin!

So, without further ado, let’s jump to this veggie egg muffin recipe!

Yum! I made some of these recently but should’ve have made extra to freeze! Great idea!
Yes!! Next time!
These looks good. I guess could substitute scrambled tofu and make ahead too.
I think that would work! If you try it, let me know!
