What You’ll Need:

Ingredients for baked stuffed portobello mushrooms including mushrooms, cheese, spinach, and seasonings

Here’s the ingredient lineup for baked stuffed portobello mushrooms—things you likely have on hand already:

  • 4 large portobello mushroom caps, stems and gills removed
  • 1 cup fresh spinach, roughly chopped (optional but brightens the filling)
  • 1/2 cup diced onion (yellow or white work great)
  • 2 garlic cloves, minced
  • 1 cup shredded mozzarella cheese (feel free to swap for cheddar, provolone, or even a cheese blend)
  • 1/2 cup cream cheese, softened (adds creamy texture)
  • 1/4 cup grated Parmesan cheese (you’ll find this near the pasta in the grocery store)
  • 1/4 cup breadcrumbs (panko or regular—if you want to skip, crushed crackers work well too)
  • 2 tablespoons olive oil
  • 1 teaspoon Italian seasoning (a simple blend you can find in the spice aisle)
  • Salt and black pepper to taste

No problem if you don’t have fresh spinach; I’ve made this baked stuffed portobello mushrooms recipe with frozen spinach off-season, just be sure to squeeze out the excess water so the filling isn’t soggy. Also, I often swap the mozzarella cheese with a cheese stuffed portobello version by adding crumbled feta or goat cheese for a tangy twist—both options taste fantastic.

This recipe stays budget-friendly because portobello mushrooms and simple cheeses are affordable staples, and the seasoning is basic pantry fare. Plus, I like to prep the filling while the mushrooms roast a bit, saving time and streamlining the process.

If you happen to have extra filling left over, it freezes well or keeps happily in the fridge for a day—great for adding to pasta or stuffing in another batch of baked mushroom appetizers later on.

One little secret I add to baked stuffed portobello mushrooms is a drizzle of balsamic vinegar right before baking—it adds subtle depth without complicating the flavor.

Let’s Cook It Together!

Here’s the step-by-step to nail these baked stuffed portobello mushrooms with ease and confidence:

  1. Preheat your oven to 375ºF (190ºC). While it warms, line a baking sheet with parchment paper or lightly grease it.
  2. Prepare the mushrooms. Clean the portobello caps gently with a damp cloth. Remove the stem and scrape out the gills with a spoon so there’s room for the filling. Lightly brush both sides with olive oil and season with salt and pepper.
  3. Roast the mushrooms for about 10 minutes. This helps draw out moisture so your baked stuffed portobello mushrooms don’t end up soggy. While they cook, you can get the filling ready.
  4. Cook the filling base. Heat a tablespoon of olive oil in a skillet over medium heat. Add the diced onion and sauté until translucent, about 3-4 minutes. Toss in the garlic and stir for another minute until fragrant.
  5. Add spinach and seasonings. Stir in the chopped spinach, Italian seasoning, salt, and pepper. Cook for 1-2 minutes until spinach wilts.
  6. Mix the cheeses and breadcrumbs. Off the heat, combine the cooked veggies with cream cheese, mozzarella, Parmesan, and breadcrumbs in a bowl. Stir until well blended.
  7. Stuff the mushrooms. Remove the pre-roasted mushroom caps and carefully spoon the filling evenly into each one, piling it up just right.
  8. Optional: drizzle balsamic vinegar. If you want that extra flavor push, add about half a teaspoon of balsamic over each stuffed portobello mushroom before baking.
  9. Bake for 15-20 minutes. You’re looking for bubbly cheese and a golden top. The baked stuffed portobello mushrooms will smell incredible—your kitchen is going to smell like a cozy trattoria before you know it.
  10. Rest briefly before serving. That way, the filling firms slightly, making them easier to handle.

From start to finish, this baked stuffed portobello mushrooms recipe takes about 40 minutes. While it bakes, use the time to prepare a simple salad or set the table, so everything comes together smoothly.

If your baked stuffed portobello mushrooms look a little too juicy when you pull them out, don’t worry—that’s why roasting at the start is key. The filling will hold together as it cools and sinks in the flavors.

I’ve found the best shortcut to keep this dish simple is prepping the filling while mushrooms roast the first time around; multitasking is your friend here!

How to Serve & Enjoy It!

Freshly baked stuffed portobello mushrooms plated and ready to eat

Baked stuffed portobello mushrooms shine as a main or starter, depending on your crowd and occasion. I often serve them with:

  • A fresh green salad dressed simply with lemon and olive oil, to keep things light
  • Roasted or steamed seasonal veggies for color and crunch
  • Warm crusty bread or garlic bread on the side to soak up any delicious juices

These baked mushroom appetizers work great for cozy weeknight dinners or when entertaining friends. They bring a satisfying, hearty feel without being heavy.

To make your baked stuffed portobello mushrooms extra special for a gathering, sprinkle with fresh herbs like parsley or basil just before serving. That green pop makes a difference in presentation.

Leftovers reheat well in the oven or microwave and taste just as good the next day. You can also chop and toss the filling into pasta or on top of pizza for a creative twist.

For holiday variations, I’ve swapped the filling with sausage and sage or added cranberries for a festive touch. If you love recipes like this, you might also enjoy the stuffed butternut squash I’ve shared before at dumafoods.com—it’s a similar satisfying vibe.

Your Questions Answered

Can I make baked stuffed portobello mushrooms ahead of time?
Absolutely! You can prepare the filling and mushroom caps a day ahead, keep them covered in the fridge, and bake just before serving. This saves tons of time and keeps flavors fresh.

What’s the best substitute for cream cheese in the filling?
Greek yogurt or ricotta cheese work well if you want a lighter option or don’t have cream cheese on hand. The texture will be slightly different, but still delicious.

How do I adjust this baked stuffed portobello mushrooms recipe for more servings?
Simply multiply the ingredients based on how many mushroom caps you can find. Baking time remains roughly the same unless you crowd the pan, in which case add a few extra minutes.

Can I make vegetarian stuffed mushrooms without cheese?
Definitely! Try replacing cheese with finely chopped nuts, nutritional yeast for a cheesy flavor, or vegan cheese alternatives, like those featured in vegan stuffed portobello mushroom recipes on Vegan Blueberry.

Will these baked stuffed portobello mushrooms work on a grill?
Yes, but watch closely. Pre-roast the mushrooms lightly and fill them, then grill over medium heat with the lid closed until cheese melts. It adds a lovely smoky note.

How do I keep the portobello mushroom filling from getting soggy?
Pre-roasting mushrooms to reduce moisture helps big time. Also, drain or squeeze out excess liquid from veggies and spinach before mixing the filling.

Are there variations to make these stuffed mushrooms heartier?
Adding cooked sausage, quinoa, or beans to your portobello mushroom filling adds protein and bulk. For inspiration, check out this stuffed portobello mushrooms baked recipe for some fun combos.

My Best Baked Stuffed Portobello Mushrooms Tips:
