Are Mushrooms Keto?

Mushrooms are naturally low in calories and carbohydrates, making them great for any keto diet. While raw mushrooms are an amazing keto choice, 

I don’t eat them raw very often. Mushrooms are commonly used in so many delicious keto mushrooms recipes.

According to the USDA website, 1 cup of raw mushrooms provides: 

  • 2.28 grams carbs
  • 0.7 grams fiber
  • 0.2 grams of fat
  • 2.16 grams of protein

We like mushrooms, and we often eat them because they are rich in vitamins, fiber, antioxidants, and nutrients that help the immune system.

Nutritionists recommend them because they are a good source of selenium, vitamin D, and B and help us balance our blood cholesterol.

keto stuffed mushrooms ingredients
  • Mushrooms – I used medium cremini mushrooms (also called baby bella mushrooms), but you can also use white mushrooms or portobello mushrooms.
  • Olive Oil – for brushing the mushrooms. You can replace it with avocado or coconut oil.
  • Butter – make sure that you use an unsalted one; otherwise, you have to reduce the amount of salt.
  • Cream cheese – it is used to make the sauce as creamy and delicious as possible.
  • Shredded Cheese – My favorite is cheddar cheese, but you can use any shredded cheese such as mozzarella.
  • Onion & Garlic – these are used to enhance the flavor of the filling.
  • Italian seasoning- my favorite herb blend. 
  • Salt & Pepper – to taste.
  • Parmesan Cheese – to garnish, but you can also add some in the filling.

How To Make Keto Stuffed Mushrooms

These stuffed mushrooms are easy to make. They look good, impress guests’ attention, and quickly disappear from the plates.

Preparing The Mushrooms

Begin by carefully cleaning the mushrooms, ensuring they are free from any dirt or debris. Remove the stems and set them aside for later use.

Season the mushrooms with a sprinkle of salt and pepper, then gently brush them with a coating of olive oil, ensuring all surfaces are covered.

Making The Filling

Start by finely chopping the onion and mushroom stems into small pieces.

In a skillet, melt the butter over medium heat. Add the chopped onion and mushroom stems, and sauté them for approximately 5 minutes until they become tender and aromatic.

Add the remaining ingredients to the skillet and continue cooking for an additional 3 minutes, allowing the flavors to meld together.

Baking Stuffed Mushrooms

Take each mushroom cap and generously fill it with the prepared filling mixture. Top each filled mushroom with a generous sprinkle of grated parmesan cheese.

Preheat your oven and place the filled mushrooms on a baking sheet. Bake them for around 15-20 minutes, or until the tops turn golden and the mushrooms become tender.

Cheese Stuffed Mushrooms Variations

Although this recipe is as delicious as it is, you can play with the ingredients:

  • Add some crispy bacon bits or sausage to the filling.
  • Another great idea is to wrap the mushrooms in bacon slices before baking them.
  • Use your favorite cheeses such as mozzarella, Gruyere, brie, goat cheese, or a combo of cheeses. So versatile!
  • Add some baby spinach or green onion to the filling.
  • Mix in some chopped pecans for some extra crunch.
  • Add sun dried tomatoes and goat cheese to the filling.
  • Make Vegan Cashew “Cheese” Stuffed Mushrooms: Soak raw cashews in water for a few hours, then drain them. Blend the cashews with nutritional yeast, garlic powder, onion powder, lemon juice, and a pinch of salt until creamy. Stuff the mushroom caps with the cashew “cheese” and bake until the mushrooms are tender and the filling is heated.

Tips For Making The Best Stuffed Mushrooms

  1. Any large mushroom will work for this recipe; you just need to make sure they are large enough to be stuffed. Remember that mushrooms reduce in size while baking.
  2. If you want to prevent your mushrooms from getting soggy, let the filling chill before stuffing the mushrooms.
  3. Prepare your filling ingredients by chopping them into small pieces that will mix together evenly.
  4. Don’t be worried if you end up with liquid around the mushrooms after you bake them because it is absolutely normal. Mushrooms have a lot of liquid inside them, which they release during baking. 
  5. Arrange the mushrooms in a single layer to ensure they cook evenly.
