Baked Eggs with Caramelized Mushrooms, Onions, and Spinach

Baked Eggs with Caramelized Mushrooms, Onions, and Spinach

I have been having fun making all sorts of variations of baked eggs like Caprese Baked Eggs, Baked Eggs with Bacon, Tomatoes, and Sharp Cheddar, and Herb Baked Eggs. I was in the mood for an egg dish for breakfast so I looked in my refrigerator to see what I had on hand. I found some leftover diced onion, spinach, and baby button mushrooms so I decided to sauté the combination then add an egg on top and bake it. I served these tasty baked eggs with a piece of really great toast (Dave’s Killer Bread – Good Seed) and they were so fantastic. My husband and I both felt these eggs were rich, creamy, and extra delicious!

  • Cooking spray
  • 1 tsp butter
  • 1 tsp olive oil
  • 1/2 sweet yellow onion, diced
  • 1 cup of baby button mushrooms, sliced in half
  • 1 cup of baby spinach
  • 3 eggs
  • 3 tsp milk (I used fat free but cream would make it richer)
  • Sea salt and freshly cracked pepper, to taste

Baked Eggs with Caramelized Mushrooms, Onions, and Spinach

Preheat the oven to 350 degrees. Coat two small ramekins with cooking spray.

Heat the butter and olive oil in a skillet over medium heat. Add the onion, and cook, stirring often, for about 3 minutes. Add the mushrooms, and cook for 2-3 minutes before stirring. Once the mushrooms are golden brown and the onions are tender, add the minced garlic and spinach to the skillet and cook, stirring continuously for 1 minute. Season with sea salt and freshly cracked pepper, to taste. Remove from the skillet and divided equally into the three ramekins.

    Eggs must be one of my favorite things to eat, I have never had a baked egg cooked like this, the only time I have had an oven cook egg is on a Florentine Pizza which goes really well with the Spinach. I am going to give this ago. Thanks!!

  22. Paula @ Dishing the Divine says:

    I tried a similar recipe eons ago that was terrible. I think it's because they didn't do like you did – they didn't cook the ingredients enough beforehand. I think your recipe looks like a real winner!!!
