What Goes Into Caprese Stuffed Portobellos
A handful of simple, fresh ingredients make these Caprese Stuffed Portobellos shine. The garlic butter gives the mushrooms their irresistible richness, while mozzarella, tomatoes, and basil bring all the classic Caprese flavors to life.
- Portobello Mushrooms: Large, meaty mushrooms act as the base, sturdy enough to hold all the cheesy, garlicky goodness.
- Fresh Mozzarella: Creamy slices of mozzarella melt beautifully into the mushrooms, giving you that signature Caprese indulgence.
- Grape Tomatoes: Sweet and juicy tomatoes balance the richness of the cheese and butter with a burst of freshness.
- Balsamic Glaze: A drizzle of tangy, slightly sweet balsamic glaze elevates the flavors and ties the dish together.
Note: Please see recipe card at the bottom for a full list of ingredients with measurements.
How To Make Caprese Stuffed Portobellos
- Preheat the Oven: Set your oven to the grill or broil setting on high heat and position the oven rack in the middle to ensure even cooking.
- Prepare the Garlic Butter: In a saucepan, melt butter with garlic and parsley until fragrant, creating a rich base for the mushrooms.
- Brush the Mushrooms: Coat the bottoms of each portobello cap with the garlic butter and place them buttered-side down on a baking tray.
- Stuff the Filling: Flip the mushrooms, brush the insides with the remaining garlic butter, then layer in mozzarella slices and tomatoes.
- Broil Until Golden: Place tray in the oven and broil until the cheese is bubbling, melted, and lightly golden.
- Finish and Serve: Top with fresh basil, drizzle with balsamic glaze, season with salt to taste, and serve immediately while warm.
To balance the rich flavors of these Caprese Stuffed Portobellos, try pairing them with something a little surprising from the sweet side of the menu. A chilled glass of Strawberry Rosé Slushies (Frosé) adds a refreshing, fruity note that cuts through the garlicky mushrooms beautifully. For dessert, Churro Lava Cakes bring a playful twist with their gooey, cinnamon-sugar filling, creating an indulgent contrast to the savory portobellos. And if you’d like to keep things light but still unique, Mango Coconut Cheesecake Parfaits layer tropical sweetness with creamy richness, making every bite feel like a sunny escape alongside the earthy mushrooms.
Recipe FAQ’s
Large portobello mushrooms are best because they’re sturdy and create a natural “bowl” for the filling, but you can also make mini versions using large white or cremini mushrooms.
No, the mushroom skin is edible and adds texture. Just clean them well and pat dry before adding the filling.
Make sure the mushrooms are thoroughly dried before brushing with garlic butter, and avoid overbaking so they hold their meaty texture.

Instructions
Stuffed Portobello Mushrooms
- Preheat oven to grill/broil settings on high heat. Arrange oven shelf to the middle of your oven.
- Combine all of the Garlic Butter ingredients together in a small saucepan (or microwave safe bowl), and melt until garlic is fragrant. Brush the bottoms of each mushroom and place them, buttered side down, on a baking tray.

Balsamic Glaze
- (If making from scratch, prepare while mushrooms are in the oven.) Combine sugar (if using) and vinegar in a small saucepan over high heat and bring to the boil. Reduce heat to low; allow to simmer for 5-8 minutes or until mixture has thickened and reduced to a glaze. (If not using sugar, allow to reduce for 12-15 minutes on low heat).

New to Cafe Delites, hi Karina!
Just made this tonight for dinner and it was a hit! Trying to do 1-2 “meatless” nights a week, and hubby is a bit hesitant. He says as long as I keep making things like this, he is down! Thank you so much, Karina!
Hi Karina!
I’d love to feature your stuffed portobello recipe in a stuffed veggie roundup I’m doing for Parade Magazine – if you’re cool with that would I be able to use one of your gorgeous photos with a link back to your original post (https://cafedelites.com/2015/07/01/caprese-stuffed-garlic-butter-portobellos/)
Thanks dear!
Felicia
Hi Felicia! Yes that’s fine thank you! Looking forward to seeing the roundup!
This was EXCELLENT. I made my own basil butter a few weeks ago frozen in icecube trays, this was the 1st opportunity I’ve had to use it. Oh my goodness, added a bit of fresh grated garlic to it and brushed it on the mushrooms! ABSOLUTELY DELISH.
Oh yum!!! Sounds incredible! I love that!
These are awesome. So much flavour we loved them. Thank you. Best site ever.
Hey Kristine you’re welcome!
Hello i was wondering if you can make them the night before a party?????? Thanks
Hi Marianna! I would say you could prepare them the night before a party, but cook them on the day as they wouldn’t be as nice the next day. The hot melted cheese makes all the difference!
I recently became a member. I LOVE THIS SITE. The photography is exceptional, recipes are new, exciting and doable for a home cook.
Wow Corrina thank you!! You’re compliment means the world to me!! Definitely just made my day X Welcome to my blog!
Man, who wouldn’t want these? Amazing flavors and photos. 🙂 I’d throw these on the grill for another layer of flavor.
Can these be done in the oven as well or do they need to be grilled?
Hi Fay! These are done in the oven with the grill (or broil) settings 😉
Thanks, “Broil” is a bit of a foreign term to us Aussies down here 🙂
Yes it is! It’s a whole different language over here 😉
These. Look. AMAZING!!! Beautiful photos Karina 🙂
Thank you Jenna! I just had a peek at your bog too…gorgeous!
Wow – these look great. I’m always looking for different ways to cook portobellos – will definitely be trying these.
Hi Geraldine! I hope you enjoy them and would love to hear how you go if you do try them! Xx
