Portobello Baked Eggs

Portobello Mushroom and Egg

I love eggs.  So much.  It’s one of the main reasons why I could never be strictly vegan, I would miss eggs way too much.  Sure, I could probably live without meat, but I know I couldn’t live without eggs or cheese.  One night as I got sucked into the ethers of Pinterest and I saw these Portobellos and eggs and I knew I had to make my own.

On Pinterest there are tons of variations, but I decided to go with just what I had: asiago and thyme, ha (grocery shopping was on my list of to-dos post breakfast).

Portobello Mushroom and EggSo first thing’s first, I cleaned the Portobellos which involves just a damp paper towel and wiping the mushrooms clean.  Washing mushrooms like other veggies, under running water, means you’re going to get water-logged mushrooms.  Because mushrooms are so porous, to clean them it’s best to just wipe them down so they don’t end up super soggy.

With the misto, I lightly sprayed a bit of oil on each side and gave each side a good sprinkle of salt and pepper.  Then I broiled them for about 3-4 minutes on each side.

Then, cap side up, I added the shredded asiago cheese,

and cracked an egg into each cap.  With the oven turned down to 400 degrees, I popped them back in on the middle rack and let them cook for about 15 minutes until the whites were nice and cooked but the yolk still perfectly runny.

Once out of the oven, a little sprinkle of pepper and some fresh parsley, and omg it looks like the pictures on Pinterest!

I’m such a sucker for a runny yolk.  That with the nice “meaty” portobello and the nutty asiago, it was a delicious vegetarian friendly breakfast.
