Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• large portobello mushrooms (stem removed, cleaned and dried)

• butter

• garlic (crushed)

• fresh parsley (chopped)

• fresh mozzarella cheese balls (sliced)

• grape or cherry tomatoes (sliced)

• fresh basil (shredded, for garnish)

• balsamic vinegar (for drizzling)

• brown sugar (optional, if you make a balsamic glaze)

Directions

1. Preheat your oven to 375°F (190°C).

2. In a mixing bowl, combine the butter, crushed garlic and chopped parsley — this will be your garlic butter mixture.

3. Place the cleaned mushroom caps upside down on a baking sheet lined with parchment paper.

4. Brush each mushroom cap generously with the garlic butter mixture.

5. Fill each mushroom cap with sliced fresh mozzarella, then top with the sliced tomatoes.

6. Bake for about 10 minutes or until the cheese is melted and bubbly.

7. While still warm, mix the balsamic vinegar (and brown sugar if using) in a small saucepan over medium heat until slightly thickened and drizzle over each stuffed mushroom before serving.

8. Garnish with shredded basil and serve hot.

Servings and timing

• Yield: approximately 5–6 servings (one stuffed mushroom per person)

• Total time: ~20 minutes (about 10 minutes prep + ~10 minutes bake)

Variations

• Swap the fresh mozzarella for goat cheese or feta for a tangier profile.

• Add a layer of pesto or a swirl of basil oil under the cheese for extra herb flavor.

• Include chopped baby spinach or arugula inside the mushroom for more greens.

• Use a flavored balsamic (for example fig or raspberry) to change the glaze dimension.

• Top with toasted pine nuts or walnuts for crunch and added texture.

Storage/Reheating

• Refrigerator storage: Store in an airtight container for up to 3 days. If stacking, place parchment paper between layers to prevent sticking.

• Freezing: Freeze for up to 2 months. First, place stuffed mushrooms in a single layer on a baking sheet to flash freeze for 1–2 hours, then transfer to an airtight container.

• Reheating:

  • Oven: Preheat to 350°F (175°C) and bake for about 10–15 minutes until heated through.

  • Microwave: Heat on medium power for about 1–2 minutes, checking frequently.

  • Stovetop: Place in a skillet over low heat, cover and warm for about 5–7 minutes.

FAQs

What are Caprese Stuffed Portobello Mushrooms?

Caprese Stuffed Portobello Mushrooms are large portobello caps filled with fresh mozzarella, tomatoes and basil, brushed with garlic butter and finished with a balsamic drizzle.

Can I make them ahead of time?

Yes — you can assemble them (up to the baking step), cover and refrigerate for up to a day before baking.

What size mushrooms should I use?

Choose large portobello caps — the size ensures you get enough room for the filling and a satisfying portion.

Can this recipe be made gluten‑free?

Absolutely. All the main ingredients (mushrooms, cheese, tomatoes, basil, butter, garlic, balsamic) are naturally gluten‑free. Just check your balsamic vinegar label if you’re strictly avoiding gluten.

How do I choose the best mushrooms?

Look for portobellos that are firm, dry (not damp or slimy) and have smooth, unblemished caps. Wipe clean rather than washing heavily so they retain structure and texture.

Can I use different cheeses?

Yes. Swapping in goat cheese, feta or even a provolone/mozzarella blend will work — just keep in mind the flavor profile will shift slightly.

What kind of tomatoes work best?

Small grape or cherry tomatoes are ideal because they’re juicy, cut easily and retain their shape. If using larger tomatoes, slice them thinly so they fit nicely in the cap.

How can I make the dish more filling?

Serve over cooked quinoa, brown rice or whole‑grain pasta, or add a side of roasted vegetables for more substance.

Is it possible to grill these mushrooms instead of baking?

Yes — you could grill the stuffed mushrooms on medium heat for around 8–10 minutes (lid closed) until the cheese melts, turning once if needed. Brush the mushrooms with garlic butter first, then add cheese and tomatoes and finish with balsamic.

What garnishes complement the dish?

Fresh shredded basil, a light sprinkle of flaky sea salt, ground black pepper or even a few toasted pine nuts or chopped walnuts add both flavor and presentation appeal.
