Philly Cheese Steak Stuffed Portobello Mushrooms

Ground beef, peppers, onions, and lots of cheese stuffed into a portobello mushroom cap to create a leaner, low carb version of the iconic Philadelphia sandwich.

The other night while scrolling my Facebook feed, I saw one of those recipe videos that a friend shared. You know the ones I mean, by Tasty or Yummly or whoever, that are sped-up, top-down, and design to make the viewer drool?

This one was for Philly Cheese Steak Sloppy Joe’s. It looked amazing. I knew instantly that I could create a leaner version of it. I also knew that bread wasn’t really worth my carbs right now, so my good friend the portobello mushroom would be the perfect substitute. Besides, who doesn’t like mushrooms on their cheese steaks as well?

People who don’t like good things, that’s who.

Ingredient line up for Philly Cheesesteak Stuffed Mushrooms

I rounded up some ingredients according to the original recipe, and some on my own. I chose lean 93/7 ground beef instead of ground chuck, but you could go higher fat, or even use OG thin sliced ribeye chopped up sandwich style if fat isn’t a concern for you.

Browned ground beef and chopped peppers and onions

The other most important ingredient is cheese, of course. For melting into the beef mixture, I used my favorite Velveeta Queso Blanco. I just love the mild taste and creamy, melty texture of this. You can use whatever you want, but choose something that melts well.

Shredded cheese added after a bit of baking

For the topping, I originally planned on sliced Provolone as you can see in the first picture… only I opened the package and discovered that it had gone moldy.

Womp womp.

So I went with whatever shredded cheese was in my fridge, some cheddar blend I think, but next time I’ll use Provolone.

The instructions for the recipe are pretty darn simple: Brown ground beef, mix in veggies, season with sauces, add in queso cheese until melted, stuff inside mushroom caps, bake, top with cheese, bake again. If you need more detail, you can find it in the recipe card below.

This dish is filling and cheesy and delicious and sure to please even the most discerning “meat and potatoes” types, while being low enough in carbs to allow for more volume in your meal. I liked to have mine with a side of cooked greens!

Recipe: Creamy Sausage & Mushroom Stuffed Chicken

Last week I became obsessed with the idea of making stuffed mushrooms. I really have no idea why. I was mostly trying to figure out something to do with the pile of cremini mushrooms in my fridge, other than just eating them on a salad like I had been. Normally cooking something, stuffing it inside another thing, and then cooking again is way too much work for me.

I looked up a few stuffed mushroom recipes and decided there wasn’t enough protein in the meals, so they would be a side dish. Ain’t nobody got that kinda time for a side dish. But now I was onto an idea of “sausage stuffed” something.

Enter, the chicken breast. Nature’s perfect meat pouch.

Everyone knows that pork and chicken go together like peanut butter and jelly. With a combination of sausage, chicken, mushrooms, and cheese, I knew I could have a winner winner chicken dinner. Literally.

I assembled some ingredients partially just based on what I had in my fridge. I chose my go-to low fat cream cheese because there really isn’t anything that isn’t improved by cream cheese. But for an extra creamy, cheesy kick, I also added some shredded KerryGold Skellig sweet cheddar (not pictured). The other base ingredients are the chicken breasts, the sausage (I love Jimmy Dean’s reduced fat pork sausage, but any sausage will do), the aforementioned cremini mushrooms, minced garlic, and some salt and pepper.

I also added some of this delicious hot sauce I found in the commissary, because I’m obsessed with it. You can leave that out if you like.

First, you’ll need to prepare the stuffing by browning the sausage and giving the mushrooms a good chopping. If you’re not using pre-shredded cheese, you’ll need to shred some cheese as well.

In a separate bowl, combine your cooked sausage, cream cheese, shredded cheese, chopped mushrooms, hot sauce (optional), garlic, and some salt and pepper. I mostly squished it together with a combination of a fork and my hands, but it’s a bit easier to mix if the sausage is still warm.

Begin by trimming the chicken breasts of any excess skin and chewy bits, and then carefully cut them into meat pockets.

I’m fully aware of their resemblance to female genitalia.


Then, liberally salt-and-pepper the outside of the pocket, and maybe the inside a little too. It’s easier to do this now than after they’re stuffed with deliciousness.

Once seasoned, you can stuff the chicken pockets with your desired amount of stuffing. The first night I made these, I stuffed waayyyy too much into them, and they became some sort of frightening chicken popover thing. Still delicious, but a bit over the top (heh).  The next night I halved the amount so I could pin the pocket closed with a couple of toothpicks so it would roast all nice and evenly.

Scary overstuffed chicken
Frightening overstuffed chicken popover thingie.

It ended up being about a quarter cup of stuffing per normal-sized chicken breast. You may need more or less depending on the size of your breasts. Um…your chicken breasts, not your actual breasts, if you have breasts, though I suppose even men technically have breasts…


Whether you have actual large or small breasts, you will need to stuff your meat pockets with as a much sausage as they can accommodate……



This is escalating quickly.

Pin them closed with some toothpicks and quickly throw them in a baking dish and into a preheated 400° oven before they continue making jokes about meat pockets and sausage.

You want to bake them until the chicken reaches an internal temperature of 165. This took about 30 minutes for mine, but that time will vary depending on your oven and the size of the chicken breasts and the thickness of the pockets. Anywhere from 25 – 40 minutes is probably a safe assumption. Pro tip: Remove the chicken when it reaches about 160 and let it rest for 5-10 minutes. During the rest period, it will continue cooking internally and the juices will pull back into the meat. Everyone likes a juicy chicken breast.

Following the resting period, remove the toothpicks, and serve with your favorite sides. I enjoy it paired with some roasted broccoli because the broccoli is great for soaking up escaped cheese sauce.

Yum! Much creamy. Much meaty. Much cheesy.

You’ll notice the recipe that follows is a bit odd. It’s a serving for one. This recipe is intended to be modified to suit you and your needs/tastes. You can very easily increase the amounts to make a whole family dinner. I found that once the sausage was cooked and mushrooms chopped, it was very easy to make this again on subsequent nights and adjust the amounts of stuffing ingredients as needed. Measure, manage, and enjoy!

Low Carb Spaghetti Squash Pizza Crust: The Recipe That Isn’t

My attempts and failures to create a super low carb spaghetti squash pizza. Not a recipe, yet. A non-recipe. Tasty, but not pizza.

So there I was, Pizza Friday just around the corner (in my house, every Friday is Pizza Friday), and I had just started a temporary low-carb cut.

I really wanted pizza.

But I really wanted to hit my numbers 100% so I could make my goals (and go back to eating carbs).

But I really wanted pizza.

I knew about cauliflower pizza crust, but having no cauliflower and no motivation to go the store, I needed to look at other options. I had a whole container of already-roasted spaghetti squash in my fridge. Spaghetti squash, if you haven’t guessed or don’t know, is somewhat starchy hard squash. When cooked, the flesh comes out in long strands like spaghetti. It’s practically flavorless and so readily accepts whatever flavors you want to add to it. I knew I wasn’t going to get an exact replica for “real” pizza crust, but I figured the starchy nature would at least let me make something passable.

And so my quest to create spaghetti squash pizza crust had begun.

Attempt 1

close up of cooked spaghetti squash

To begin, I took my pre-measured amount of spaghetti squash and put it in a food processor with some reduced-fat cream cheese, a good amount of salt and pepper, a half teaspoon of minced garlic, a drizzle of olive oil, and a sprinkle of oregano and basil. I didn’t want the long strands of squash to linger in my crust, so the processor helped chop it up a bit. Note: if you’re making this from freshly roasted squash, you’ll need to squeeze the moisture out of the squash between two paper towels. Mine had been in the fridge so was already pretty dry.

Next, I spread the mixture out on a piece of parchment paper and pressed it into the shape of a circle, roughly the size of a personal pan pizza. It ended up about ¼ inch thick or just under. I was hoping for crispy crust!

Squash mixture pressed into crust form

Then, since this was prep for dinner hours later, into the fridge it went.

A few hours, a daycare pick-up, and a taekwondo class later, it was pizza time!

I pulled the crust from the fridge and transferred it, parchment paper and all, to a baking sheet. Then I topped it with all my favorite pizza accoutrement: Turkey pepperonis, pizza sauce, mozzarella cheese, and more oregano sprinkled on top. Then I popped it into a pre-heated 450º oven along with my kids’ Totinos Party Pizza (trying not to be jealous of their dinner) for about 10 minutes.

Squash "crust" with pizza toppings

The result was…. Not pizza. The crust browned but didn’t crisp. And it didn’t hold together. What I had was a baked spaghetti squash pizza casserole patty… thing.

Yet, it tasted amazing. I had a chicken breast on the side of my dinner for additional protein, and the two of them went perfectly together. So it wasn’t a total loss.

Finished spaghetti squash "pizza"

But I still really wanted pizza.

Attempt 2

The next night, now having a vendetta against this pizza crust, and still having all of the ingredients on hand, I decided to try it again.  

This time I used the blender instead of the food processor, hoping to blend the squash down to smaller bits. I also reserved the olive oil for later. I repeated the rest of the process of pressing the mixture down onto parchment paper into a crust-like form.

Next, I added that drizzle of olive oil to my trusty carbon steel pan and heated it up nice and hot.

Then through some weird feat of juggling acrobatics, I attempted to flip the crust into the pan and off the parchment.


It mostly stuck to the parchment and came off into the pan in chunks.

Ok, no worries. Nobody panic. I just smooshed the pieces together in the pan and hoped for the best. It started frying nicely and smelling awesome. I waited until it was a nice golden brown shade on the bottom before I checked the integrity of the “crust” and found it a bit wanting. Yet I was hopeful. I added my pizza toppings. Rather than attempt the disaster of a transfer again, knowing my crust structure was not yet there, I stuck the whole pan in the oven, again at 450, for 15 minutes.

Fifteen minutes was far too long. My bad.

The crust browned, but so did the cheese. <cry>

Burned spaghetti squash "pizza"

And it also fell apart, again. It was just a more well-done version of the previous night. It was still delicious on chicken and I still ate every bit, but admittedly the less toasty version was a bit better.

And it still wasn’t pizza.

So here we stand and I’m back to the drawing board.

I would try again tonight except it’s Princess Peanut’s birthday and I promised her spaghetti with meatballs, as has been our tradition for the last 2 of her 3 years.

I’ll try again for round 3 for the next Pizza Friday and report back, but here are my ideas so far.

  • Add an egg to the mixture to help bind it or
  • Add mozzarella to the mixture to bind it
  • Refrigerate, then brown in pan, then bake
  • Bake without toppings and then bake a few more minutes with toppings
  • Say “fuck it” and just stick it in a casserole pan and call it deep dish pizza

Do you have any ideas for me to try? Remember I’m trying to keep this as low carb as possible, so I would like to avoid adding any flour. Drop your thoughts in the comments!
