Ingredients for Baked Stuffed Portobello Mushrooms including mushrooms, spinach, cheese, quinoa and tomatoes

Here’s my intentionally simple ingredient list for creating crowd-pleasing Baked Stuffed Portobello Mushrooms. No stress if you don’t have everything listed—I often swap ingredients based on what’s in my pantry or produce drawer.

  • 4 large portobello mushrooms, stems removed and cleaned (You can find these in the regular produce section)
  • 1 cup cooked quinoa or brown rice (keeps this stuffed mushrooms recipe nourishing and hearty)
  • 1/2 cup chopped spinach or kale (feel free to swap with any leafy green you have)
  • 1/2 cup diced tomatoes or sun-dried tomatoes (adds moisture and flavor)
  • 1/2 cup shredded mozzarella or cheddar cheese (for irresistible cheese stuffed mushrooms—you can use vegan cheese too)
  • 1/4 cup finely chopped onion (use shallots if you want a milder flavor)
  • 2 cloves garlic, minced (fresh garlic always wins but garlic powder works in a pinch)
  • 2 tablespoons olive oil (budget-friendly and adds richness)
  • Salt and pepper, to taste
  • Optional: 1/4 cup toasted pine nuts or walnuts (for crunch and extra nutrition)

This Baked Stuffed Portobello Mushrooms recipe stays budget-friendly by using a few pantry staples combined with fresh vegetables. For busy days, prep the quinoa or rice ahead and swap fresh spinach with pre-washed baby spinach to speed things up. Leftovers store well in an airtight container for up to three days—perfect for grab-and-go lunches or quick dinners.

Personally, I love adding extra cheese on top to get that melty, golden finish. It’s a little indulgence that feels special but still nourishing.

Let’s Make It Together!

1. Preheat your oven to 375°F (190°C). While that warms up, gently clean your portobello mushrooms with a damp cloth or paper towel to get rid of any dirt. Remove the stems carefully and set those aside—they’re great to chop up and add to your stuffing.

2. Prepare your filling. In a medium skillet, heat 1 tablespoon of olive oil over medium heat. Toss in the chopped onion and minced garlic, cooking until fragrant and translucent—about 3 minutes. Add the chopped spinach or kale and cook just until wilted, around 2 minutes.

3. Mix your stuffing. In a bowl, combine the cooked quinoa or rice with your sautéed veggies. Stir in diced tomatoes and half the shredded cheese. Season this mix with salt and pepper to your liking. If you’re craving some crunch, sprinkle in those toasted nuts now.

4. Stuff the mushrooms. Drizzle a bit of olive oil on the mushroom caps to keep them juicy during baking. Spoon generous amounts of your stuffing into each portobello, pressing lightly so it sticks but doesn’t overflow.

5. Bake your masterpiece. Place the stuffed portobello mushrooms on a lined baking sheet. Pop these into the oven and bake for about 20 minutes—your kitchen will start smelling oh-so-good by now! Toward the last 5 minutes, sprinkle the remaining cheese on top to melt and slightly brown.

6. Rest and enjoy. Once baked, let your Baked Stuffed Portobello Mushrooms cool for a couple of minutes before serving. This is a great time to set the table or prepare a simple side salad.

In my kitchen, this Baked Stuffed Portobello Mushrooms usually takes about 30 to 40 minutes total, which is perfect for weekdays when time is tight but you still want something nourishing. Don’t worry if the mushrooms look juicy or slightly wrinkled—they’re perfectly baked and ready to enjoy.

A quick kitchen tip: if you want to save time, use pre-cooked grains or frozen chopped spinach. I also learned that overfilling the mushrooms can make them hard to handle, so balance is key.

How I Love to Serve This!

This Baked Stuffed Portobello Mushrooms really shines as a simple weeknight dinner but also steps up beautifully for casual weekend meals with friends. I often pair it with a crisp mixed greens salad dressed lightly in lemon vinaigrette—that fresh acidity cuts through the richness beautifully.

Another favorite is serving it beside roasted sweet potatoes or a bowl of creamy soup. The warm, cozy feel of the mushrooms complements these sides, creating a balanced vegetarian stuffed mushrooms dinner without overthinking.

For presentation, I like to sprinkle fresh herbs, like parsley or basil, on top just before serving. It adds a fresh pop of color and makes the dish feel just a little more special. Leftovers hold up well too and make a great lunch when reheated or even cold on a toasted sandwich.

Seasonally, I’ve swapped ingredients like sun-dried tomatoes for roasted red peppers or added kale when spinach was out of season. It’s these little changes that keep the dish feeling fresh without losing the comforting vibe.
