A Mushroom Convert

As a child, I never ate mushrooms. I don’t for the life of me know why.

As an adult they quickly became part of my diet, using them to bulk out other meals. Only more recently have mushrooms become center stage in my cooking.

Garlic mushrooms are a favorite dish of mine.

Mushrooms only contain 3.3 grams of carbs per 100 grams making them fairly low-carb and a good source of protein.

For anybody living a keto life, keeping carbs low to remain within your macros and not knock your body out of ketosis is key. If you are new to keto, check out our keto beginners guide.

A Garlic Love Affair

My mother hates the smell of garlic so garlic wasn’t something we ever cooked with. When I started eating out with friends a whole new world opened up to me. Suffice to say, I’ve never looked back.

Just so you know, my mother loves my cooking – and it’s laced with garlic!

I see this as my revenge for her hiding vegetables in food when I was a child! It just proves that what goes around comes around.

Back To The Garlic Mushrooms

Within 15 minutes of even thinking about it you can have beautifully browned and aromatic garlic mushrooms ready to devour.

This really is a simple dish with only four main ingredients. It makes the perfect keto side dish. You can oven bake these, air-fry them, or even cook them on the stove in a pan.

Mix up your mushrooms!

For this recipe, I have used button mushrooms as this is what I had in. However, cremini mushrooms are my favorite by far.

Cremini mushrooms are a more mature version of the common white mushroom that is found in the shops. They are not as aged and meaty in texture as portobello, which is also an excellent choice. In my opinion, cremini and portobello are superior options.

Why Cremini?


Due to their texture, they absorb more of the buttery and gallic taste-making your keto garlic mushrooms have a much richer flavor.

As with all of my recipes– you have to be realistic about the ingredients that you have access to.

When you have the opportunity please try this recipe with something other than button mushrooms.

I personally buy cremini and portobello dry, in bulk then they are there when I need them.

Once open I store them in Lock & Lock to make sure they’re airtight and last for longer and are there whenever you need them.

Buying in bulk is also great if you are trying to do keto on a budget, or are in a rush and need cupboard ingredients on hand.
