These keto stuffed mushrooms with chorizo swap nuts for bread crumbs to make an amazing low-carb appetizer that everyone will love, thanks to its rich, cheesy, and boldly flavored filling.
I adore a stuffed mushroom. It seems like such an elevated appetizer, but it’s quite approachable. And it involves the use of cream cheese, which is almost always a guarantee of deliciousness. Cream cheese elevates these winning dishes: white chicken chili and creamed kale with cream cheese!

It's also an easy appetizer to make low-carb; a simple swap of breadcrumbs for nuts is all that's required to make many stuffed mushroom recipes friendly to those looking to cut carbs.
That and I quite like the tender crunch of the nuts in the stuffed mushroom filling. Breadcrumbs play binder well, but don't add much texturally to stuffed mushrooms. Even if you're not following a low-carb diet, this variation is SO worth trying because it's delicious with a satisfying, subtle crunch.

Ingredients
- Stuffing mushrooms: Choose mushrooms that can be easily eaten in a single bite -- especially when serving for parties. I find common button mushrooms work well as do baby bellas (creminis).
- Chorizo: Chorizo has such a lively, bold flavor that using it as a stuffed mushroom filling means your seasoning is done for you. I recommend using high-quality chorizo - I picked my chorizo up locally from an Eastern European Deli called Kramarczuk’s. Grab some extra so you can make these chorizo street tacos for dinner this week!
- Shredded cheddar cheese: I recommend that you grate it from the block rather than using preshredded cheese; it melts better.
- Pecans: Use crushed salted and roasted pecans for the best flavor.

Substitutions & Additions
The above-mentioned ingredients are what my Chorizo Stuffed Mushroom recipe calls for, but you could also successfully use:
- Pepper jack, mozzarella, or other good melting cheese in place of cheddar
- Add a hard cheese to the melting cheese mix, like feta or Parmesan. For instance, why not try a cheddar + Parmesan mix or a mozzarella + feta mix? Try adding 1 tablespoon of a hard cheese, then adjusting as necessary.
- Ground beef, pork, or chicken, seasoned to your liking. Try this dry rub adobo seasoning, it's great on everything!
- Walnuts or almonds are great options in lieu of pecans. I may have to test pistachios, that sounds like it would be delicious, no?
- Fresh herbs like parsley, thyme, or rosemary add freshness, or sneak some dried herbs into the cream cheese mixture like basil or oregano to add earthiness.
Remember, recipes are only guidelines :).
How to Make Keto Stuffed Mushrooms - Directions
To get started, preheat the oven to 350° Fahrenheit, cook the chorizo and garlic in a pan on the stovetop, clean and prepare the mushrooms, and gather the rest of the ingredients. More instructions can be found in the recipe card below.
- Arrange your cleaned mushrooms on a plate, leaving space between each cap. Cover with three layers of damp paper towels. Microwave the smaller mushrooms for around 2 minutes and 3 minutes for the larger mushrooms.
- Mix together the cream cheese and pecans in a bowl, and then add the grease-drained chorizo and mix again.

- Use your hands to stuff a bit of the cream cheese mixture into each mushroom cap. I like to add a generous amount with a spoon. Bake the mushrooms for 10 minutes on the middle rack in your preheated oven.

- Increase the oven temperature to 400° F. Remove the baking sheet from the oven and add a pinch of shredded cheese to each stuffed mushroom. Continue baking.

- Bake again on the top rack for 3-4 minutes to melt the cheese. Sprinkle on crushed nuts immediately after for crunch, optional. Cool for 2 minutes and then serve warm. They're great served as an appetizer for a holiday or dinner party with Instant Pot turkey breast or air fryer chicken thighs for dinner.
Expert Tips
- Do not skip the pre-microwave steam step! Do this each and every time, and your chorizo-stuffed mushrooms will turn out fantastic every time.
- Separate the mushrooms by size. This way you can cook them appropriately in the microwave. Smaller mushrooms need less time than larger ones.
- Give the mushrooms a good once-over. Don't feel obligated to use every mushroom you purchased; if there are mushrooms that feel or appear mushy or waterlogged, avoid using them. Compromised mushrooms may not support the appetizer filling and/or may result in an unpleasant texture once cooked (read: super mushy).
- Storing leftovers. These are best enjoyed freshly made, but you can store any leftovers in the fridge for up to three days. Reheat them in the air fryer, oven, or microwave until heated through.
- Have leftover filling? Don't waste it! Spread it on a cracker or tortilla chip as a quick snack while you wait for the stuffed mushrooms to be done.
Keto Stuffed Mushrooms Recipe FAQs
Many stuffed mushroom recipes call for the use of breadcrumbs, which is a no-go if you are following a keto or low-carb diet. I swap out the breadcrumbs for crushed pecans, but walnuts would also be a good option. You don’t need to subscribe to any kind of diet to appreciate how delicious these stuffed mushrooms taste.
Nope. Don't do it. Frozen mushrooms are *really* only good for dishes where their shape or texture doesn't matter, like adding to soups or hot dishes (casseroles). Freezing mushrooms compromises their structure, texture, and flavor, and when thawed, they become mushy because of their high water content. So you're definitely not going to want to freeze stuffed mushrooms - make 'em with fresh mushrooms or not at all.
Not really. Since you are microwave steaming the mushrooms before assembling you'll want to bake them as soon as possible afterward. Steaming introduces more moisture into an already moist mushroom. The longer they sit after steaming, the more likely they will take on mushy qualities, and you don't want that.
You MUST microwave steam your ‘shrooms. Say what now!? The key to perfectly baked stuffed mushrooms is you have to steam them in the microwave first. This softens them up and speeds up the baking process. If a recipe tells you that you only need to bake your stuffed mushrooms for 10 minutes (no pre-streaming instructed), you’re going to be cooking those bastards for a half-hour until they are finally done. And by then your filling will be overcooked. And you’ll be hangry and wishing you could have the last hour of your life back.
