🧊 Storage & Reheating Tips
Caprese Stuffed Garlic Butter Portobellos are best enjoyed fresh out of the oven, but if you have leftovers, you can store and reheat them properly to maintain their flavor and texture. Here’s how to keep them tasting great:
🧴 Storage Tips
- Refrigerator: Place leftovers in an airtight container and store in the fridge for up to 3–4 days.
- Layering tip: If stacking is necessary, place parchment paper between layers to prevent the cheese from sticking.
- Avoid sogginess: Let the mushrooms cool completely before storing to reduce excess moisture.
❄️ Note: This dish is not freezer-friendly due to the high water content in mushrooms and fresh tomatoes, which can become mushy when thawed.
🔥 Reheating Tips
To bring back the flavor and texture, choose your reheating method wisely:
- Oven (Best method):
- Preheat to 350°F (175°C).
- Place mushrooms on a baking sheet.
- Cover loosely with foil to retain moisture.
- Bake for 10–12 minutes until heated through.
- Air Fryer:
- Set to 325°F and heat for about 5–7 minutes.
- This method keeps the tops crispy without drying out the mushrooms.
- Microwave (Not recommended):
- If in a rush, microwave on medium power for 1–2 minutes.
- Be aware this may cause the mushrooms to become soggy.
Proper storage and reheating will help you enjoy the same delicious, garlicky, cheesy goodness even days after cooking!
