How To Prepare Portobello Mushroom Stuffed With Caprese

Ideal for your Super Bowl party is this low-carb snack. Or, eliminate the balsamic glaze to make them Keto-friendly! I promise you will not be disappointed.

Each tasty taste will leave a lasting impression on all of your guests.

If I’m being really honest, the garlic butter is not optional because the flavor combination is incredible!

  • Before brushing the portobellos with butter, thoroughly wipe dry them with paper towels to prevent them from releasing too much liquid or water when cooking.
  • Garlic powder is whisked into melted butter. Apply the garlic butter all over the mushroom caps.
  • Put cheese and tomato slices inside the caps.
  • Bake the cheese until it melts.
  • With a drizzle of balsamic glaze and fresh basil, remove from the oven.

As an appetizer, stuffed mushrooms are our ultimate favorite. Change the larger mushroom caps with the smaller creminis for a bite-sized choice.

Can mushrooms be pre-stuffed?


You may prepare this recipe for stuffed mushrooms up to two days in advance. Just put the mushrooms together, wrap them in plastic, and put them in the fridge. Before roasting, remove mushrooms from the refrigerator for about 30 minutes to let them loosen up.

Don’t bake the mushrooms; instead, prepare them as directed. For up to three months, freeze prepared stuffed mushrooms in an airtight container. Thaw them entirely before cooking if you want to roast them.

  1. Preheat oven to grill/broil settings on high heat. Arrange the oven shelf in the middle of your oven.
  2. Combine all of the Garlic Butter ingredients in a small saucepan (or microwave-safe bowl), and melt until the garlic is fragrant. Brush the bottoms of each mushroom and place them, buttered side down, on a baking tray.
  3. Flip and brush any remaining garlic over the insides of each cap. Fill each mushroom with the mozzarella slices and tomatoes, and grill/broil until cheese has melted and golden in color (about 8 minutes).
  4. To serve, top with the basil, drizzle with the balsamic glaze and sprinkle with salt to taste.

Vinegar Glaze

  1. If making from scratch, start while the mushrooms are baking. In a small saucepan over high heat, combine the sugar (if using) and vinegar and bring to a boil. Simmer for 5-8 minutes, or until mixture has thickened and reduced to a glaze, on low heat. (If without using sugar, allow reduction on low heat for 12–15 minutes.)


*Use a dry sheet of paper towel per mushroom when drying portobellos, and gently press the sheet into each mushroom to squeeze out the extra moisture.

The portobellos will release a lot of liquid while cooking if this procedure is not done carefully.
