I love this Italian sausage stuffed mushrooms recipe. It’s the ultimate healthy dinner that manages to be hearty at the same time. And bonus, these sausage stuffed portobello mushrooms are naturally low carb, keto, and gluten free. I love when that happens. Sometimes recipes need a few (or a lot!) of tweaks to turn them into low carb and keto favorites. But other times, the tweaks are minimal and easy sausage stuffed mushrooms are just that. These keto sausage stuffed mushrooms are stuffed with a flavorful Italian sausage filling (similar to my keto stuffed mushroom appetizers) that’s been cooked with marinara sauce and basil. Then, it’s stuffed into portobello mushroom caps, topped with cheese, and broiled until golden brown.

So back up a few years… did you know that this was my FIRST recipe I ever posted on Wholesome Yum?! If you’ve been here since the beginning, you may recognize it, even though the pictures have improved (HA!). But it was time for an update with tips, etc. If you’ve been here since the beginning, THANK YOU! And if you’re here now, THANK YOU! I’m so grateful for your support and inspiration. 🙂

Back to the sausage stuffed portobello mushrooms. I love portobello mushrooms – they are so versatile! You can fill them with just about anything savory and it almost always turns out amazing. They make the perfect vehicle for all kinds of toppings.

Between the Italian sausage, the marinara, the fresh basil, and the cheese…well this combination makes for the best sausage stuffed mushrooms in my opinion! I used pepper jack cheese for a kick, but feel free to use any cheese that you like. You can also substitute slices of cheese instead of shredded, if that’s what you have. This recipe really isn’t fussy at all, which is also one of the reasons that I love it so much.

Oh, and I also love how simple it is. I can prepare the filling for these low carb stuffed mushrooms while the mushroom caps roast in the oven. The mushroom caps and Italian sausage filling will be done around the same time. After that, simply assemble and broil them for a few minutes to melt the cheese.

So easy!

How To Cook Italian Sausage Stuffed Mushrooms

This easy sausage stuffed mushroom recipe may be simple, but the flavors are complex and oh-so-good.

Let me show you the three simple steps for how to make stuffed mushrooms with sausage:

Trim and bake mushrooms. Remove the stems from the mushrooms, being careful to not break the mushroom cap. Bake just until softened.

TIP: Some people prefer to scrape off the ribs of the mushrooms – you can do this if you like. I think they are delicious and definitely not worth extra work to remove.

Make the stuffing mixture. Brown the Italian sausage and then add garlic, marinara, basil, salt, and pepper to the pan. Cook until heated through.
Stuff the mushrooms. Blot any extra liquid from the mushroom caps and top with Italian sausage mixture.
Broil. Top with shredded cheese and broil until slightly browned.

Can Easy Sausage Stuffed Mushrooms Be Made Ahead?

Most healthy stuffed portobello mushroom recipes like this one are best made fresh, but you can definitely prep the filling ahead of time.

Simply brown the Italian sausage and mix in the rest of the filling ingredients. Separately, pre-bake the mushrooms. Let cool and store separately in the refrigerator. When it’s time to bake your sausage stuffed portobello mushrooms, simply add the filling, bake to heat, and then broil until cheese has melted and it’s golden brown.

Can You Freeze Sausage Stuffed Portobello Mushrooms?

Italian sausage stuffed mushroom caps can be frozen. But, the high water content in mushrooms makes them a little trickier than some other vegetables when it comes to freezing.

Some stuffed mushroom recipes recommend freezing them before baking at all, but I find they get too watery this way. Instead, here is the best way to freeze stuffed mushrooms:

Pre-bake the empty mushroom caps, but less than fully cooked (about 1/2 the time).
Pat the mushrooms dry.
Make the filling and stuff the mushrooms.
Assemble and freeze.

To reheat:

Let the mushrooms thaw in the fridge, with paper towels underneath to absorb water.
Bake.

What To Serve With Keto Sausage Stuffed Mushrooms

This easy sausage stuffed mushroom recipe is so versatile and can go with so many different sides! I actually love them as a meal on their own, but I also think keto low carb salads make the perfect addition to hearty keto stuffed mushrooms with sausage.

Chopped Italian Keto Antipasto Salad – Perfect Italian flavors to accompany the portobello mushroom stuffed with Italian sausage.
Easy Chopped Avocado Caprese Salad – Caprese salad gets a healthy upgrade with the avocado addition.
Chopped Mediterranean Salad – This flavorful salad dressing MAKES the salad.
Italian Marinated Artichoke Salad – Classic flavors on a bed of peppery arugula.
Colorful Rainbow Salad – If you love your salads colorful (who doesn’t?!), try out this salad with a wide range of veggies and crunch.

Could I use the brown cremini mushrooms for an appetizer size portions? Would I still want to pre bake the mushrooms?

  Hi Barrie, Yes, You could do that. I have never tried that, but I don’t think you would need to pre-bake smaller mushrooms.

Yesterday I grilled Turkey Pattie’s mixed w/Mexican Chorizo I found them too bland so I broke up the patties in the skillet and proceeded with this recipe OH MY! talk about flavor! Had lots of meat mixture leftover so I froze it until I purchase more mushrooms Thank You for all your awesome recipes Maya!

  Hi Adele, The recipe is the one on this page. It happens to be naturally keto friendly, but there’s nothing diet-specific about it and you can easily enjoy it even if you don’t follow that lifestyle.

    Hi Maya, I think the confusion maybe: on a list of Ground Turkey Keto recipes from Parade Magazine, #51 comes to this ‘pork’ sausage recipe. Perhaps in the past, ground turkey was an ingredient? I just bought ground turkey so was looking for flavorful recipes today. And also to let you know, I have used your wonderful keto eggplant lasagna recipe! And I do cook with pork sometimes. My marinara recipe is similar to yours, but I brown the spicy sausage first, then the onions brown in the fat, so I don’t add extra olive oil, then the garlic, seasonings, crushed tomatoes, red wine, and simmer. My hubby is the eggplant lasagna maker, and your recipe is great.

My first recipe from the WY recipe app; so simple and delicious!! My Hubby loved it too!

I just have one comment and a question; I substituted hamburger for the sausage and the meat sauce quantity was enough to top six mushrooms instead of four, which is great because I bought a pack of six portabella mushrooms.

My question is, which side is the face of the mushroom?? Top or bottom?

  Hi Julie, So glad you liked it! The filling to mushroom ratio can vary depending on how big your mushrooms are. To answer your question, when it says bake face up, it means with the ribbed side up. Hope this helps.

This is a very versatile base recipe. Didn’t have marinara sauce on hand so subbed a can of diced tomato (onion and garlic flavor). I had cheddar, not pepper jack cheese, so added some kick with some red pepper flakes. Served it with some steamed broccoli which I also melted some cheese over.. because why not? Definitely had too much filling for only four mushroom caps but I’ll find something to do with it..

Sounds like an excellent recipe but you list it as 5 servings, call for 4 mushroom caps, and then say the serving is one large mushroom cap with filling. If that’s the case then your calories are way off. Please let me know which is correct – is this 5 servings at 336 calories or 4 servings at 420 calories each. Glitches happen and I understand but this needs correction.

Love your recipes. I made the beef and cabbage soup with coleslaw this past weekend and it was a hit. It is definitely added to my cool weather rotation of comfort foods.

Question: The recipe calls for 4 large mushrooms, but it says serving size is for 5 servings….trying to figure out my macros. is a serving only 3/4 of a mushroom? or would making 5 mushrooms and everything else the same basically keep the macros as is?

Total success!! The man said “don’t change a thing the next time you feel like making this”
And this is from someone who ALWAYS has to add his twist on everything! Lol
I DID add a sprinkle of fresh parmesan when they came out of the oven.
Thanks!!

I just made this tonight and it was not the best…I think it needs more cheese or bread crumbs. The mushrooms came out too soggy because I baked it for 15 minutes. I don’t think I would make this again….

  Hi Jessica, did you drain or blot the liquid out of the mushrooms after they were baked? That could have caused the soggy consistency.

I’m not sure I did my mushrooms right, which side is “face up”? they kind of shriveled up and there was a lot of juice that I poured out of the dish. They were also kind of flat and not bowl shaped so the “stuffing” really just sat on top. I also just used my favorite spaghetti sauce so it cut it down to just 4 ingredients. Other than my (possible) confusion, it was delish! I used 8 mushrooms and still had lots of the turkey mixture left over so I added some breadcrumbs and Parmesan cheese and made 20 meatballs!
- Maya | Wholesome Yum
  0 April 9, 2018Reply
  
  Hi Sabrina, Face up would be the round part down, bottom of the cap up. Maybe I didn’t make that clear enough, sorry! The recipe card says to drain or blot extra fluid from the mushrooms to get rid of the juice you are talking about. The amount of turkey mixture does vary depending on the size and shape of the mushroom caps. I’m glad you still thought they were delicious and found a way to use up the rest of the meat!

Is it one portobello cap per serving?
- Maya | Wholesome Yum

  Yes. The ones I used were large – about 4″ across. You may get more or less of them depending on the size you have and how deep they are.

  Hi Felicia, I’m so glad you liked it! The amount of stuffing will vary depending on the size of the mushrooms, so sometimes I have some left over too. It works well as a topping for all kinds of things later. 🙂
