Eggs baked in portobello mushrooms are lovely for breakfast and are perfect when you have people over for brunch.

They are actually substantial enough to serve as a filling lunch or even as a meatless dinner.

The combination of mushrooms and eggs is a classic one. There are several ways to go about it, but my favorite is to stuff portobello mushrooms with eggs and bake them in the oven.

These breakfast mushrooms are a gorgeous and filling dish. I make them quite often because everyone always raves about them.They are ready in about 30 minutes, and they're quite easy to make.

You'll only need a few simple ingredients to make this tasty breakfast. The exact measurements are listed in the recipe card below. Here's an overview of what you'll need:

Portobello mushrooms: I suggest you try to find ones that are similar in size and that are not too deep. This will ensure that the eggs will cook evenly.

Olive oil spray: I love cooking with this delicious oil. But if you'd rather use an oil with a higher smoke point, you can use avocado oil instead.

To season: Kosher salt, black pepper, and garlic powder.

Eggs: I normally use large eggs, but in this recipe, it's better to use medium eggs.

Parmesan cheese: It's best to use finely grated cheese and not coarsely shredded.

Chopped parsley: I use it mostly for garnish. It does greatly enhance the appearance of this dish.

Expert tip

The mushrooms are the stars of the show here, so choose them well. It's best to use large, firm portobello mushrooms. You don't want them too flat (or the egg will spill) or too deep (or the egg will take forever to cook).

Frequently asked questions

Should I remove the gills?

Yes, it's best to remove them, although not mandatory. Removing the gills helps prevent the mushrooms from releasing too much water and becoming soggy.

Do you wash mushrooms before using them in a recipe?

You should clean mushrooms, but it's best to do so with damp paper towels. If you wash them they'll absorb water and become soggy.

How can I prevent the mushrooms from being soggy?

Here's what you can do to ensure the mushrooms are not soggy:

1. Wipe them clean, don't wash them (they absorb water).

2. Remove the gills. They tend to release a lot of liquid (I admit to not always doing this!).

3. Pre-broil them to release some of the water.

4. During the final step of baking, bake just until the egg whites are cooked. Baking too long will result in mushy mushrooms that have released their liquid into the eggs. But even if that happens, do not despair: carefully drain the liquid, and place the mushrooms on paper towels to soak as much of the liquid as you can.


The best way to vary this recipe is to add spices. In addition to salt, pepper, and garlic powder, you could sprinkle the eggs with a little onion powder, chili powder, or red pepper flakes.

Serving suggestions

These tasty mushrooms make a fun weekend breakfast, a great lunch, or a filling meatless dinner when served with a salad or some steamed veggies.

When I make them for dinner, I often serve them with a simple side of tomato salad. This makes for a delicious and colorful meal.

Storing leftovers

This dish is best enjoyed right away. If you must keep leftovers, do so only if the eggs are fully cooked.

Place the leftovers on paper towels in an airtight container (to absorb extra liquid) and keep them in the fridge for up to 3 days. Replace the paper towels daily. Reheat them in the microwave, covered, on 50% power.

These breakfast mushrooms are in fact substantial enough to serve as a filling lunch or a meatless dinner.

  • 4 large portobello mushrooms
  • Olive oil spray
  • ½ teaspoon Diamond Crystal kosher salt divided
  • ½ teaspoon black pepper, divided
  • ½ teaspoon garlic powder
  • 4 medium eggs
  • 2 tablespoons grated Parmesan cheese
  • 4 tablespoons chopped parsley for garnish


  • Preheat the broiler, setting the temperature to high. Set an oven rack in the middle of the oven. Line a rimmed broiler-safe baking sheet with foil.

  • Wipe the mushrooms clean with a damp paper towel. Gently twist off or cut the stem of each mushroom. Holding each mushroom in one hand, use a spoon to gently scrape out the gills.

  • Spray the mushroom caps with olive oil cooking spray on both sides. Sprinkle with ¼ teaspoon kosher salt, ⅛ teaspoon pepper, and ¼ teaspoon garlic powder. Broil until just tender, about 5 minutes on each side.

  • Remove the mushrooms from the oven. Drain any liquids. Switch the oven from broil to bake, setting the temperature to 400 degrees F.

  • Break an egg into each mushroom. If your eggs are large, you'll probably need to break each egg into a small bowl and pour some of the egg white out before pouring it into the mushrooms.

  • Sprinkle the mushrooms with the cheese. Bake until the egg whites are cooked, about 15 minutes.

  • Sprinkle the eggs with the remaining ¼ teaspoon salt and ⅛ teaspoon pepper. Garnish with parsley and serve.



The FDA recommends cooking eggs thoroughly.

During the final step of baking, bake just until the egg whites are cooked. Baking too long will result in mushy mushrooms that have released their liquid into the eggs. But even if that happens, do not despair: carefully drain the liquid, and place the mushrooms on paper towels to soak as much of the liquid as you can.

    Delicious, but I had to cook the eggs separately because my mushrooms flattened when cooking. How do I keep that rounded shape?

      Hi Lisa,
      I'm not sure, as that hasn't happened to me. But if I were you, I would try to buy deeper mushrooms next time.
