Stuffed Mushroom Cap

Cherry Tomato & Spinach Stuffed Portobello Mushrooms

As I was slicing up mozzarella for my children’s Margherita pizza, I became envious because it looked so good. Unfortunately, it wasn’t gluten-free and I couldn’t have any. Meal making in my house can be a little tricky at times. So, I opened up the fridge, looked through all of the drawers and frantically searched for something to whip up that was equally satisfying. Staring me in the face was a package of beautiful portobellos that I was saving to grill up as burgers. I also found a bowl full of fresh cherry tomatoes that I had picked from our garden. Thirty minutes later, I was left with a gluten-free version of the Margherita pizza I had just made. This one was all mine!! Just kidding I made some for my husband too. I’m not that evil.

  • 4 large Portobello Mushrooms, stem removed, washed and dried

  • Fresh mozzarella

  • 2 cup cherry or grape tomatoes

  • 4 ounces of baby spinach

  • 2 tablespoons olive oil

  • ¼ teaspoon salt

  • a dash of ground black pepper

  • 2 tablespoons of fresh chopped basil

  • For the garlic butter
  • 2 tablespoons butter

  • 1 clove garlic, minced


  • Filling
  • In a medium non-stick pan, heat up olive oil
  • Add tomatoes to the pan and sauté. Once they plump up and begin cracking, smash to release on the juices. Add salt and pepper and stir.
  • Once tomatoes are cooked and you get a thick sauce, turn off the heat and stir in the spinach. This may take 30-40 minutes depending how watery your tomatoes are.
  • When they are close to being done, preheat oven to broil. Arrange shelf to the middle of your oven.
  • Portobello Mushrooms
  • Combine the minced garlic and butter in a small saucepan and melt until butter is browned and fragrant. Turn off the heat. Brush the tops of each mushroom with the butter and place top side up on a baking tray.
  • Place baking sheet in oven for 5 minutes. Next, flip over the mushrooms, holding them up for as few seconds so all of the water comes out of the bottoms and brush with any remaining butter.
  • Slowly and very carefully, fill the bottoms of each mushroom cap. Top with thin slices of fresh mozzarella and chopped basil.
  • Place back into oven and cook 5 more minutes or until cheese has melted and started bubbling.
