Eggs baked in portobello mushrooms are lovely for brunch and substantial enough for a filling lunch or a meatless dinner.
I really love portobello mushrooms. Much like eggplants, they give a vegetarian experience that’s very meaty! They are substantial, filling, and very flavorful.
Portobello eggs are a gorgeous and filling dish. I make them quite often because everyone always raves about them. The only drawback is that they can become soggy – but I have a few good tips for preventing that.
The ingredients you’ll need
You’ll only need a few simple ingredients to make this tasty recipe. The exact measurements are listed in the recipe card below. Here’s an overview of what you’ll need:
Portobello mushrooms: I recently found out that they are the mature version of cremini mushrooms. Interesting. 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.
How to make portobello eggs
It’s a truly easy recipe. Scroll down to the recipe card for the details. Here are the basic steps:
1. You broil portobello mushrooms.
2. Then break an egg into each mushroom cap.
3. Bake until the egg whites are set.
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) nor too deep (or the egg will take forever to cook).
How to prevent sogginess
There’s one challenge when making this recipe, though. Stuffed and baked portobellos can become soggy. To avoid sogginess:
1. Wipe the mushrooms 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. In 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.
How to serve portobello eggs
They 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.
