Stuffed portobello mushrooms: an overview
Alex and I have made quite a few stuffed portobello mushroom recipes in our day, but this one is the absolute best. Why? Because the filling is our famous spinach artichoke dip, which without fail wows everyone who dips into it with a hunk of crusty bread. Use this as the filling for stuffed portobello mushrooms, and transforms them into a delicious vegetarian dinner or a fancy side dish. Here’s the outline of how to cook portobello mushrooms:
- Bake the mushrooms: You’ll add olive oil, salt and pepper, then bake at 450 degrees for 15 minutes. Then drain out the liquid. See more below!
- Make the filling: Stir together the spinach artichoke filling using spinach, artichokes, Greek yogurt, mayo, Parmesan and spices.
- Stuff the mushrooms: Add the filling and top with Italian panko or Italian breadcrumbs. Bake another 10 minutes at 425 degrees.
Tips on how to cook portobello mushrooms: baked or roasted!
The best way to cook whole portobello mushrooms is baked or roasted, which makes them beautifully tender and brings out the savory, meaty flavor. You can do this to make a portobello burger, or it works great for stuffed. There are a few things to note about baked portobello mushrooms:
- Remove the stems before baking. This is important because the stem is tough and hard to cut into. It also makes it easier to stuff!
- Bake until just tender, but not falling apart (15 minutes). When making stuffed roasted portobello mushrooms, you want the cup shape of the mushroom cap to stay in tact. Overbaking them can lead to collapse.
- Important: drain all the liquid before stuffing! Portobello mushrooms contain 90% of their weight in water. That means once they’re roasted, you’ll notice water has accumulated in the caps. It’s perfectly normal and expected: just make sure to drain off and discard all liquid that is released.
What’s Italian panko? Is there a substitute?
- Use regular panko and add salt and Italian seasonings. Mix ⅓ cup panko with ⅛ teaspoon kosher salt and ½ tablespoon Italian seasoning (or 1 teaspoon dried oregano and ¼ teaspoon each dried basil and thyme)
- Or look for Italian or plain breadcrumbs instead, or make your own breadcrumbs! For plain breadcrumbs, use the seasoning recommendations for panko above.
Make it a meal!
Once they’re baked and stuffed, pull them out of the oven and take a bite. You’ll taste meaty mushroom, spinach artichoke dip, and a little breadcrumb crunch: it’s extraordinary! This recipe works very well as a vegetarian dinner recipe with a few side dishes. Or you can use it as a fancy side dish and pair it with steak or fish! They’re great for a dinner party, or even a romantic dinner like Valentine’s Day.
Remember if you’re serving them as a meatless main, add side dishes full of plant-based protein. Here are a few ideas to accessorize roasted portobello mushrooms:
- Salad: Try Arugula Salad, Goat Cheese Salad with Arugula, Chopped Salad, Brussels Sprouts Salad, Fennel Apple Salad, Fennel Orange Salad, Frisee Salad or Endive Salad
- Beans: Ideal for adding plant-based protein to a vegetarian meal! Add Borlotti Beans, White Beans, or Cannellini Beans.
- Rice or quinoa: Add Rice or Perfectly Seasoned Quinoa.
- Farro or couscous: Try simple and delicious Farro with Herbs, or Easy Couscous.
- Roasted vegetables: Serve with Best Roasted Vegetables, Epic Roasted Broccoli or Roasted Asparagus with Lemon.
- Sautéed vegetables: While the mushrooms bake, make a pan of Ultimate Sauteed Vegetables.
All about portobello mushrooms
Want to know more about the mighty portobello mushroom? Here’s what you need to know about this popular mushroom variety:
- The portobello mushroom (aka portobella or portabella) is one of the most widely consumed mushroom varieties in the world, called Agaricus bisporus. The button mushroom and cremini (aka baby bella) are the same variety of mushroom, just earlier growth stages than the portobello. The portobello is the oldest stage, so it has the most meaty and savory flavor.
- Where to find it? You can find the portobello mushroom at most mainstream grocery stores. Often it comes packaged in containers with 3 to 6 mushroom caps.
- What does a portobello mushroom taste like? Portobello mushrooms taste intensely meaty and savory, with loads of umami. While they taste meaty, remember to add protein to the meal if you’re making them as a vegetarian main dish! They don’t contain much protein in themselves.

This recipe is delicious! I veganized it by using vegan cream cheese, vegan mayo, vegan grate parmesan, etc….AND I used canned hearts of palm instead of artichoke. It’s super yummy!
Love recipe for best ever stuffed portabello mushroom.
Made this for dinner and it was delicious. It’s just my husband and me so cut recipe in half and did some estimating on amounts. Tweaked a few ingredients based on what I had on hand but pretty much followed recipe as written. I Added some sun dried tomatoes because I had sent that in another portobello recipe. Will definitely make this again.
Question: Can these be frozen?
They won’t freeze well.
