What You’ll Need for This Baked Stuffed Portobello Mushrooms:
- 4 large Portobello mushroom caps – wiped clean and stems removed. You want big ones for the perfect stuffing base. You can find these at most grocery stores, usually in the vegetable section.
- 1 cup breadcrumbs – plain or seasoned, both work well. If you don’t have breadcrumbs, crushed crackers or oats can be a quick easy swap.
- 1/2 cup finely chopped onions – yellow or white onions work fine. Pre-chopped frozen onions can save you time here.
- 2 cloves garlic, minced – fresh garlic is best but jarred minced garlic works in a pinch.
- 1 cup shredded cheese – mozzarella, cheddar, or a blend. For a vegetarian stuffed mushroom twist, try a dairy-free cheese or nutritional yeast.
- 1/2 cup finely chopped bell peppers – optional, but adds a lovely crunch and pop of color.
- 1/4 cup chopped fresh parsley or spinach – packed with flavor and color. Frozen spinach can be squeezed dry and used here if fresh isn’t available.
- 2 tablespoons olive oil – for sautéing and drizzling over mushrooms.
- Salt and black pepper – to taste.
- 1/4 teaspoon dried oregano or Italian seasoning – for that classic herb note.
- 1/4 cup cream cheese or ricotta (optional) – gives the stuffing a creamy texture that’s hard to resist.
This baked stuffed Portobello mushrooms recipe uses simple ingredients because I believe great baking should be easy to start with what you have. Plus, it’s affordable! Most of these ingredients are pantry staples or everyday veggies. Don’t shy away from swapping out the veggies for whatever’s fresh and seasonal. I always add a bit extra parsley for that bright freshness and a touch of extra shredded cheese on top before baking to get that golden melty finish.
Quick prep tip: Have your filling ingredients chopped and ready before you start sautéing. The mushrooms don’t spend long in the oven, so everything else should be lined up to go. Lastly, store leftover mushrooms in an airtight container in the fridge, and the filling ingredients will keep their flavor best if chopped fresh.
For those who want to step outside of my recipe, you might also enjoy the Vegan Stuffed Portobello Mushrooms for a dairy-free and plant-based version that tastes amazing.
How to Make This Baked Stuffed Portobello Mushrooms:
- Prep your mushrooms: Start by gently wiping the Portobello caps with a damp cloth to remove dirt. Remove the stems and set aside (you’ll chop these for the stuffing). Brush each cap with olive oil, and sprinkle lightly with salt and pepper. This helps them cook tender but keeps them juicy.
- Make the stuffing: Heat 1 tablespoon olive oil in a skillet over medium heat. Add the chopped mushroom stems, onions, bell peppers, and garlic. Sauté until soft and fragrant, about 5 minutes. You’ll want to stir often so nothing sticks or burns. Your kitchen already smells fantastic, right?
- Combine the filling: Transfer the sautéed veggies to a bowl. Stir in breadcrumbs, cheese, parsley or spinach, cream cheese if using, and the dried oregano. Mix everything until combined but not mushy. Taste the mixture and adjust salt and pepper—seasoning is key here.
- Stuff the mushrooms: Preheat your oven to 375°F (190°C). Place the mushroom caps gill side up on a lined baking sheet. Spoon the portobello mushroom stuffing evenly into each cap, packing it gently but not too tightly. This is the step where a gentle hand really makes all the difference!
- Bake: Place your stuffed mushrooms into the oven and bake for 20-25 minutes. You want the mushrooms tender but still holding their shape, and the stuffing golden and set. If you like, add a bit more cheese on top for the last 5 minutes to get a gooey crust.
- Rest and serve: Let the baked stuffed Portobello mushrooms rest for a few minutes after coming out of the oven. This helps the flavors settle and the filling firm up slightly so they’re easier to handle.
From start to finish, this baked stuffed Portobello mushrooms recipe takes about 45 minutes, making it a fantastic option for weeknight dinners or last-minute entertaining. While they bake, you can tidy the kitchen or prepare a simple side. If your mushrooms look plump and golden on top, you’re on track for a winner.

Serving Your Baked Stuffed Portobello Mushrooms:
One thing I love about baked stuffed Portobello mushrooms is their versatility on the table. They work beautifully on their own for a light vegetarian main or appetizer, but they also pair well with fresh salads or a warm side like roasted potatoes. A simple green tossed salad with a vinaigrette adds a refreshing contrast to the rich, savory mushrooms.
For gatherings, these baked mushroom appetizers always get a lot of love. People appreciate the hearty texture combined with a comforting flavor profile. You can add a sprinkle of fresh parsley or a dash of paprika on top for a bit of color flair—no fancy decor required.
Leftovers here make for fantastic sandwich fillings or a topping for toasted bread. I’ve even chopped the leftover filling into pasta or stirred it into scrambled eggs for a tasty twist the next day.
Seasonal variations, like adding chopped sun-dried tomatoes in late summer or swapping in kale for the spinach in colder months, keep this recipe feeling fresh all year. My family especially enjoys when I use seasonal veggies for the portobello mushroom stuffing.

Common Questions About This Baked Stuffed Portobello Mushrooms:
Can I make this Baked Stuffed Portobello Mushrooms ahead of time?
Absolutely! Assemble the mushrooms with stuffing and refrigerate them for up to 24 hours before baking. Just add a few extra minutes to the baking time if they come straight from the fridge.
What’s a good substitute for breadcrumbs in this recipe?
I’ve swapped breadcrumbs for cooked quinoa or crushed nuts when I’m out of crumbs. Both give a nice texture to the portobello mushroom stuffing and keep the dish gluten-free if needed.
Can I freeze Baked Stuffed Portobello Mushrooms?
You can! Bake them first, then cool completely and freeze in an airtight container. Reheat in a 350°F oven until warmed through, about 15-20 minutes. Freezing before baking is trickier because mushrooms release water as they thaw and can get soggy.
How do I keep the mushrooms from getting watery?
Brush the caps with olive oil and don’t overcrowd them on the baking sheet to allow steam to escape. For the portobello mushroom stuffing, draining veggies if too wet can help a lot.
Can I make this recipe vegan?
Definitely. Swap the cheese for a vegan cheese or nutritional yeast, and use a non-dairy cream cheese or skip it entirely. There’s a wonderful variation on Vegan Blueberry for Vegan Stuffed Portobello Mushrooms with helpful tips.
How do I adjust this for different pan sizes?
If your mushrooms are smaller, you might want to cut the recipe in half or gather more caps for a crowd. This recipe scales well. Just keep an eye on the baking time; smaller mushrooms may bake faster.
What else can I add to the portobello mushroom stuffing for extra flavor?
I like adding chopped sun-dried tomatoes, toasted nuts, or even a bit of cooked sausage if I’m not keeping it vegetarian. Fresh herbs like thyme or basil bring a lovely twist, too.
