Vegetarian Stuffed Portobello Mushrooms Recipe - Rachel Cooks® (2024)

You won’t want to miss these vegetarian stuffed portobello mushrooms, overflowing with a creamy blend of three cheeses and crowned with crisp savory breadcrumbs.

Looking for a wonderful meatless main dish? Look no further. Mushrooms feel meaty so they satisfy the carnivores in your family — just hand them a steak knife and watch them dig in. I have a feeling that no one will be complaining.

(Still feel like you need a little meat? I do have a couple of recipes for meat-stuffed mushrooms. Try Coq Au Vin Stuffed Mushrooms or Chicken Parmesan Stuffed Portobello Mushrooms.)

But today, we have vegetarian stuffed portobellos and boy, are they good! Melty, creamy cheese, with zippy little bites of sun-dried tomatoes mixed in, topped with crisp buttery garlicky bread crumbs — oh, yes, I’ll take these any day. You’re gonna love them!

About this mushroom recipe

There are three easy steps to this recipe:

1. Prepping the mushrooms so they’re ready to stuff;
2. Mixing up the creamy filling and spooning it into the mushroom caps;
3. Making the breadcrumb topping.

Allow yourself about twenty minutes for prep and another fifteen minutes oven time.

I’ll get you started here but you’ll find the printable recipe card near the end of the post. It has complete instructions, measurements, and nutrition information.

Ingredients you’ll need

• Portobello Mushrooms: You’ll need four mushrooms, large enough to hold lots of the luscious filling. Want to make six servings instead? There’s enough filling for six smaller sized mushrooms. Alternatively, you can fill several small mushrooms for a great appetizer.
• Olive Oil: A light coating of olive oil keeps the outsides of the mushrooms from drying out. Season with salt and pepper.
• Sun-Dried Tomatoes: I like the tomatoes that aren’t packed in oil. Chopped finely, they add tangy flavor and little chewy bits which is a nice jazzy contrast to the creamy stuffing.
• Lots of Cheese! Creamy ricotta, gooey mozzarella, and flavorful Parmesan — the perfect trio for these stuffed mushrooms.
• Fresh Chopped Basil: Don’t you just love the sharp aroma of fresh basil?
• Bread Crumb Topping: These stuffed mushrooms boast a crispy panko crown, with melted butter, garlic, parsley, and oregano. Regular bread crumbs are okay, too, and gluten-free bread crumbs are also available. Did you know that you can make homemade bread crumbs? It’s a great way to use up day old bread and they are very easy to make.

How to make Stuffed Portobellos

First, prepare the mushrooms. Brush them clean, scrape out the gills, and twist off the stem.

Lightly brush the outsides with olive oil, and season the insides with salt and pepper.

Next, stir together the three cheeses, finely chopped sun-dried tomatoes, and fresh basil.

Spoon the filling into the mushroom caps.

Okay, last step — the topping. In a small skillet, melt butter. Add minced garlic and cook briefly. Add the panko and Italian seasonings. Crown the mushrooms with this savory topping.

Pop the pan into the oven and bake. It will take about fifteen minutes for the cheese to get melty and the topping to brown. So yummy!

What to serve with stuffed portobello mushrooms

Vegetarian stuffed portobello mushrooms are a healthy meatless main dish. Serve them with a fresh green salad like this classic arugula salad or tomato cucumber salad.

Stuffed mushrooms also are a filling side dish, perfect with air fryer salmon, easy baked salmon with lemon and chives, spice rubbed pork tenderloins, or this bruschetta chicken.

What wine goes well with mushrooms? Stuffed portobello mushrooms have a meaty texture and robust flavor, almost like a steak. Accordingly, choose the same wine you would serve with a steak. Try a fruity Zinfandel or Cabernet Sauvignon. A full-bodied craft beer is good, too, like stout or brown ale.

FAQs

Make It Your Own

• Add spinach and/or onion (finely chopped) to the filling.
• Change up the cheese. Instead of mozzarella and Parmesan, try Swiss or Gruyere.
• Make it southwestern. Add a little taco seasoning to the filling (omit the basil and oregano), and use a Mexican cheese blend.
• Make it into an appetizer! Instead of large portobello mushrooms, fill white button mushrooms (stems removed). Bake as directed.
• Grill the mushrooms: Put mushrooms on a preheated grill (medium heat), cover and cook until cheese is melted and mushrooms are cooked, about 10 minutes. Note: The panko topping won’t get as crisp. You may want to put them under the broiler for a few minutes. Or, try grilled portobello mushrooms with spinach and cheese.
• Looking for sautéed mushrooms instead? Try the best sautéed mushrooms (I have an easy trick!), air fryer mushrooms, or sautéed mushrooms with wine and garlic. Roasted mushrooms are delicious and easy, too.
• Not a fan of mushrooms? Try or boursin cheese stuffed zucchini. Caprese couscous stuffed tomatoes are delicious, too, and also pizza stuffed spaghetti squash.

Make-Ahead Ideas

To get a head start on this meal, mix up the filling and prepare the breadcrumb topping the night before. Refrigerate both until you’re ready to stuff the mushrooms. You’ll need to add a few minutes to the baking time.

Storage & Reheating Tips

Lucky you, leftover mushrooms! Refrigerate up to three days, tightly wrapped. To reheat, put the mushrooms on a baking sheet and into a preheated oven (400°F) for ten minutes or until heated through.
