Eggs are always an easy go-to when it comes to a filling breakfast, and these Eggs Baked in Portobello Mushrooms are perfect for a low carb Sunday brunch, or breakfast when you have a little bit more time to cook your eggs. Protein packed eggs, baked in a mushroom for a low carb alternative to putting them on bread and a layer of chopped spinach for a vegetable portion first thing.
This is one of our favourite low carb breakfasts. You just add some greens to a large mushroom cap, crack an egg in to it, season and put in the oven until the egg is cooked to your liking. There are so many ways you can adapt this recipe too, with different vegetables or even some chopped up bacon.

How to make eggs baked in mushrooms - Step by step
One: Peel the Portobello mushroom caps "skin" so they are no longer dirty. This is better than washing them, as they will absorb water. Remove the stalks.
Two: Place on a baking tray, stem side up.
Three: Divide the spinach and basil between the mushrooms.
Four: Carefully crack an egg into each mushroom.
Five: Season with salt and pepper and bake in a preheated oven at 200°C/400°F/Gas 6 for 15-18 minutes, until the white of the egg is cooked.
Health benefits of eggs
Eggs are delicious and nutritious, not to mention a great budget friendly ingredient for making versatile meals. They are a great source of protein, Omega-3s and "good" cholesterol. They are a good source of vitamin B12, B6, vitamin D, selenium, and other important minerals! Also, mushrooms with their really meaty texture, are a great source of vitamin D, Iron and Potassium.
I think these are a pretty impressive brunch option to serve to a crowd, if you want something that takes almost no effort at all. The great thing about them is that they are so easy to adapt.
We just added loads of spinach, as our green vegetable intake has been a little on the low side recently, but you could add peppers and onions or even some ham/bacon if you want meat in them.
If you wanted to jazz these up even more, then add some cheese on top and they are kind of like breakfast mushroom pizzas. These are a great way to use up leftovers. You can also add in some cooked and chopped sausage or bacon.
If you are eating them by themselves, then a pinch of good sea salt and pepper adds loads of flavour. We are also partial to a good splash of hot sauce on these too.
Some kind of bread is a must with eggs, right? We love serving these with our Homemade Easy Bagels. Or if you want to try making your own loaf of bread, then why not try our Easy White Loaf Recipe? You could also fold them up in our Homemade Flatbreads with some beans, salsa and guacamole for a breakfast wrap/burrito.
If you want something extra with your eggs, then we recommend some bacon and our Air Fryer Bacon recipe keeps it a lighter option. You could also add sausages (see how to cook sausages in the oven), smoked salmon or mushrooms.
These are best eaten straight away, however if you do have any leftover then you can put them in an air tight container and store them in the fridge until the next day.

• Use the best quality and freshest eggs you can, as it will make a difference. Place the egg in a bowl of water, and if it sinks, it is fresh. Floating eggs should be thrown away because they are too old.
• Let refrigerated eggs reach room temperature before cooking.
• You don't have to use spinach in this, you can swap it for other leafy greens like kale.
• Want more of a meaty dish? Add some chopped cooked bacon at the same time as the spinach.
• Make sure you season these eggs really well - it really will make a difference to the flavour. Seeing as this is such a simple recipe, a generous pinch of sea salt and black pepper will be needed.
