This is the perfect way to elevate your breakfast! Mushroom caps are the best baking vessel for all of your breakfast favorites. Whether you’re using them for meal prep, brunch, or weekend breakfasts, they’re the way to go!

When I went to make these, I realized that it was ‘tween time. ‘Tween time is the time between two major meals (breakfast and lunch, for example) when you find yourself positively starving. Since I only had a protein shake for breakfast, my Buddha belly was rumbling fiercely.

This dish was embarrassingly easy to make. The hardest part is cleaning the gills out of the mushrooms. The biggest key to cleaning them out for this dish is not to go too thin, break the walls, or poke a hole in the bottom of it. If you do, your egg will leak out.

Chef Lori’s #1 Tip for Cleaning Mushrooms

  1. Gently twist off or cut off the stem of each mushroom.
  2. Grab a mushroom in one hand and cradle it. Use a soup spoon in your other hand to scrape the gills off, moving in a circular path right around the edge of the mushroom.
  3. The gills will come out very easily, so you don’t need a lot of pressure—in fact, push too hard, and you may go right through the mushroom, so tread lightly. If needed, you can go back over it a second time.

What’s awesome about these is that they suit most folks’ dietary lifestyles—paleo, gluten-free, low-calorie, skinny, or if you’re like Mr. Fantabulous, you eat everything under the sun.

I honestly can’t wait until Lent to make these for lunch every Friday and every day. What I love about food like this is that you can add whatever you want.

When you make these, how long you cook them is up to you. I like my whites cooked all through, but the yolks runny.

Some folks get wigged out by that, and that’s cool.  You don’t have to eat it.  As I show you below, you can make them however you want.  The key is to get the whites set.  That’s most important. Why?  If they aren’t set, if you try to cut into them, it’ll end up being a huge mess on your plate/

Stuffed Mushroom FAQs

  • Do I have to remove the gills? The gills are edible, but for this recipe, you need the space.  Plus, if you left them in the egg whites, they would turn muddy in color.
  • How do I keep the mushrooms from getting soggy? Not all mushrooms are the same, so if you want, you can pre-bake the mushrooms (unstuffed) for a few minutes before adding the breakfast stuffing.
  • Can I prepare these ahead of time? Sort of. You can remove the gills and prepare the fillings already, but I would not ‘stuff them’ until you’re ready to bake them.

Breakfast Stuffed Mushroom Variations

  • Protein Lovers: Add chopped ham, sausage, bacon, and cooked chorizo into the mix

How to Store Leftover Stuffed Mushrooms

These are best enjoyed right away. However, you can store the leftovers. The only thing to remember is that your eggs must be fully cooked.

Egg Stuffed Skinny Portabello Caps5
  1. Place paper towels in the bottom of an airtight container.
  2. Place the fully cooked stuffed breakfast mushrooms on top (once cooled), close the lid, and keep them in the fridge for up to 3 days.

Even though the mushrooms are cooked, they will still seep liquid, so change the paper towels daily.

To reheat, pop it back into a preheated 350°F oven for a few minutes until warm.

  • Method: oven
  • Cuisine: keto friendly breakfast, brunch recipes, healthy breakfast, stuffed mushrooms, meal prep recipes, gluten free breakast

Ingredients

  • 4 large portobella caps (about 4-5” round), cleaned, plus stalks and gills removed – be careful not to break the sides or bottom
  • 1–2 teaspoons olive oil
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon black pepper
  • 8 large eggs
  • 1 tablespoon chopped chives
  • Add-ins: crispy bacon, shredded cheddar, chopped spinach, pancetta, ham, sausage.

Instructions

  1. Preheat the oven to 400°F, with the rack in the upper third. Line a baking sheet with foil and place a cooling rack on top.
  2. Take a pastry brush and brush the outside of the mushrooms. Set the mushroom cap size up on the cooling rack. *if desired, bake the mushrooms for about 2-3 minutes to release some of the water in them to avoid having them turn soggy. Remove from the oven and then proceed by adding bacon, spinach, pancetta, or other add-ins.
  3. Carefully crack two eggs into each cap (if you can only fit one, only add one). Sprinkle with salt and pepper.
  4. Place in the oven and bake for 15-25 minutes or until the whites are opaque and set. The yolks will be runny when the whites are set, but you can cook for longer if you do not want runny yolks.
  5. Remove from the oven and enjoy!

    I can’t wait for Lent to try these! I guess no bacon during Lent. 😐

    Thank you for another low carb recipe. I’m not super strict (last weekend I made the orange cranberry cake) but I try for as many low carb options as I can. This will be added to my weekend breakfast rotation.

      You are most welcome 🙂 Also just so you know if a recipe of mine isn’t low-carb or keto friendly I’m more than happy to work with you to help make it that way. Plus I have a huge TKW Family population on Facebook that are Keto and Low carb so they too can help with the recipe modifications.

      Merry Christmas and best Kitchen Wishes!

    My eggs didn’t turn out as good as yours is pictured but it didn’t taste bad at all. I added chopped asparagus. Chopped up the stems. Added chunks of cheese and pepperoni. I think next time I’ll scramble the eggs. Overall a fantastic quick dish! Loved it.

    These look amazing. How long do they need to cook, to be solid (like the ones on the left side)? May have to scramble those eggs…I can’t handle runny ones.

      Hi Clare!

      If you don’t like runny yolks go for 20-25 minutes. The yolks will set way faster than the whites. I’ve actually been making an omelet of sorts with scrambled eggs in this. I’ll sautee up my veggies, put them in the mushroom cap and beat 2 eggs together. Pour that into the cap and bake. That takes about 15-20 minutes to be set and still fluffy.

      Best Kitchen Wishes!
