I love stuffed mushrooms as a yummy side dish or appetizer. When they’re stuffed with crab meat they can easily double as a main dish too. These stuffed portobello mushrooms feature melted mozzarella cheese and cherry tomatoes for a delicious Caprese version.

Stuffed Portobello Mushrooms

There are so many different filling options when it comes to mushrooms. A lot of recipes use panko breadcrumbs, but I’ve found they’re just as delicious without. You can use parmesan cheese, cream cheese, or goat cheese to add a creaminess. Or try some veggies, diced artichoke hearts, or sauteed red bell peppers for stuffing. They’re also great with a little fresh parsley or a drizzle of balsamic vinegar over the top.

This Caprese mushroom version is low-carb, gluten-free, and keto friendly. I like to finish them with a light drizzle of homemade raspberry vinaigrette. You could also add some fresh chopped oregano or freshly cracked black pepper after cooking too.

The garlic infused butter sauce adds another layer of flavor to these. And the melted mozzarella combined with the tangy tomatoes and fragrant basil tastes so good.

Different Types of Mushrooms

I use large portobello mushrooms for this recipe. Their size and meaty flavor really work well. You can use other types of mushrooms as well. The typical white mushrooms you see at the grocery store are simply the baby version of portobellos. If left to mature, the white mushrooms start to darken and develop more flavor. This middle stage is sold as cremini mushrooms. Then when they’re fully developed they become portobello mushrooms.

So portobellos have the most mushroom flavor and the least water content of the bunch. If you prefer though you could use white mushrooms, cremini, or baby bella for this recipe.

Prepping the Mushrooms

Once you have your mushrooms the next step is to get them ready to stuff! You’ll start by removing the mushroom stem… easy enough. I like to save these for other dishes, like stir fry or omelets.

Next, you can give your mushrooms a quick rinse to remove any dirt. Traditionally, the recommended way to clean mushrooms is to simply wipe the outside with a damp paper towel. Mushrooms absorb water really well, so submerging them in water can impact the flavor.
