Ingredient Checklist


Instructions Checklist
  • Preheat oven to 400 degrees F.

  • Combine 2 tablespoons oil, garlic, 1/4 teaspoon salt and 1/4 teaspoon pepper in a small bowl. Using a silicone brush, coat mushrooms all over with the oil mixture. Place on a large rimmed baking sheet and bake until the mushrooms are mostly soft, about 10 minutes.

  • Meanwhile, stir tomatoes, mozzarella, basil and the remaining 1/4 teaspoon salt, 1/4 teaspoon pepper and 1 tablespoon oil together in a medium bowl. Once the mushrooms have softened, remove from the oven and fill with the tomato mixture. Bake until the cheese is fully melted and the tomatoes have wilted, about 12 to 15 minutes more. Drizzle each mushroom with 1/2 teaspoon vinegar and serve.


Tip: To prepare portobello mushroom caps, gently twist off the stems of whole portobellos. Using a spoon, scrape off the brown gills from the underside of the mushroom caps. If you prefer, purchase portobello mushroom caps, rather than whole mushrooms.

Next time I will lower the oven temp to 350 or 375 F. The mushrooms get very overcooked otherwise. I served the mushrooms on a bed of mixed greens tossed with a tiny amount of Italian salad dressing. The recipe is absolutely scrumptious! Read More

I literally never review recipes but i made an account just to review this one. I made this recipe exactly except for i used a bit extra garlic and quartered the tomatoes instead of halving them. I paired with steaks. This recipe made my steaks seem boring. 10/10. only problem was that they did flatten a bit. not great presentation but INCREDIBLE taste. Read More

Oh.my.LANTA! These are amazing. Made as per the recipe although I used a tbsp. of minced garlic (not sure how much that is in comparison to a clove & was too lazy to Google). I will prep the mushroom caps a little differently next time as they flattened a lot and released quite a bit of liquid during the first bake. Wound up more like a pizza at the end LOL. Not as pretty as pictured in the recipe but so delicious! Will definitely be making these again and often. Thanks!! Read More

Made as written and the flavor was very good! However I had a hard time with the mushrooms. I didn't have any prior experience with portabello. They kinda flattened during the first 10 minutes of baking and it made it very difficult to fill them. In the future I will make sure to purchase ones that have a deep rim on them. Read More

Excellent! The only change I made was as to line each mushroom with fresh baby spinach. My husband and I enjoyed two smaller mushrooms each with no sides. Read More
