Portobello mushrooms are the gold standard in meat-substitute veggies. They’re dense, meaty, mild in flavor, and very budget-friendly.
Their round cup shape is also perfect for stuffing in yummy ingredients like mozzarella, Roma tomatoes, fresh basil, and a drizzle of balsamic reduction.
All you have to do to create these caprese stuffed portobellos is fill the mushrooms, stick them under the broiler, and devour.
I have to be honest, caprese is awesome, but it’s really just a fresh vehicle for balsamic vinegar for me. You can totally buy some at the store, but it’s really easy to reduce the balsamic at home, too. Here’s a tutorial for reducing balsamic.
Once you’ve made it, you can drizzle it all over everything you’re making like roasted Brussels sprouts and balsamic strawberries with mascarpone cream.
One of the greatest parts of this recipe is actually optional, but SO worth it: the brown butter wash on the outside. Still new to browning butter? You’re in for a treat — here’s how to do it. Brown butter is flippin’ de-li-cious. Brush it on to the bottom of the mushrooms for added depth of flavor like you won’t believe.
I’d definitely recommend these caprese stuffed portobellos for a fast and easy weeknight meal, but they’re also pretty shmancy for a dinner party, as long as you can serve them fairly quickly. Nothing makes caprese lose steam faster than the cooling of the mozzarella. Serve it piping hot while it’s ooey gooey. (More cheesy recipes can be found here, btw!)
And of course, they’re awesome for vegetarian pals. The final result is low carb, gluten-free, grain-free, and pretty healthy so it’ll fit within a lot of nutritional needs if you’re serving a crowd.
