Ingredients and substitutions
- Olive oil – swap out for any neutral cooking oil like canola oil or grapeseed oil.

- Red pepper – see substitution notes above for green peppers.
- Red onion – yellow or white onion can be used in a pinch.
- Mozzarella cheese – Swiss cheese would also be yummy on these stuffed peppers.
- Salt & pepper – to taste.

Making keto stuffed peppers
While this meal is low carb, at 12 grams of net carbs per serving, it's not low enough for keto. With a few easy swaps, you can easily make this recipe keto friendly!
If you're following a keto diet and want to bring the carb count even lower, try these solutions:
- Zucchini boats are a great alternative to the green bell peppers since they've got just a little over half as many net carbs.
- Green onions/scallions are a safer bet for keto recipes because they have about half the carbs as red onion.
Making these simple changes will bring the net carb count down to about 6 grams of carbs per serving.
Frequently Asked Questions
Bell peppers aren’t a necessity in Philly cheesesteak – the main components of an authentic Philly cheesesteak sandwich are bread, steak, cheese and onions. A lot of places add peppers because they provide a nice crunch, but adding them isn’t a hard and fast rule. This recipe combines all your favourite flavours of the classic sandwich but without all the carbs!
There’s no boiling required for this stuffed pepper recipe. You just need to cook the peppers for about 10 minutes in the oven at 400° Fahrenheit before stuffing them. After you’ve stuffed them, cook them for another 15 minutes.
Some people like to have a softer pepper “shell” instead of a firmer one. If this is you, it's really easy to make them that way! Heat your oven to 375° Fahrenheit instead of 400° Fahrenheit. Stuff the peppers but leave off the cheese and cover them with aluminum foil. Bake for an hour before removing the foil lid, then add the cheese, salt and pepper. Bake for another 5 to 10 minutes until the cheese melts then serve!
Crispy roasted potatoes are the perfect companion for these stuffed peppers! Cube them, oil them up, and season them before tossing them in the oven with the empty green pepper halves. Then they'll all finish up together! You can also serve your stuffed peppers with a side of cauliflower rice to keep the carbs down.
Storing and reheating
These stuffed peppers are great for meal prep. You can even assemble the peppers the day before and store them in the fridge before their final bake! Just add 10 minutes on to the baking time and you’ll be good to go.
You can store the leftovers in the fridge in glass meal prep bowls for 3 to 5 days. Reheat them in the oven in a foil-covered baking dish for 30 minutes at 375° Fahrenheit with some fresh cheese over top. You could also reheat them in the microwave, but the peppers will get a bit soggy using that method.
Can you freeze stuffed peppers?
Yes, you can! The texture won't be exactly the same, but they do fare pretty well in the freezer. Cover and freeze your fully cooked peppers in the baking dish once they're totally cooled. They should last in the freezer for up to 3 months.
When you’re ready to enjoy, let them defrost in the fridge overnight then bake them uncovered in the oven for 30 minutes at 375° Fahrenheit. Alternatively, you could freeze the steak and vegetable mixture by itself and then add it to fresh peppers and bake as normal.

Comments & Reviews
Lisa says
I’m excited about the recipe I will be enjoying these cooked for the final process in the air fryer, since it’s too hot for the oven. I will cook the stuffed peppers (I’m following your yummy recipe) at 390 degrees for 10 minutes. I can’t wait. I just know they will be delicious. Thanks😊
Taylor Stinson says
Ooooh interesting that you cooked them in the Airfryer!!! Hope they turned out well for you 🙂
Ally says
Hi! Could I use shaved steak? Would I cook it completely before baking in oven?
Taylor Stinson says
You could use shaved steak for sure! I would add it in raw, it should get cooked in that time.
Kellie says
After reading some of the comments we revised just a bit:
-instead of cutting the peppers in half we just cut the tops off
-Season the veggies with lawry’s in addition to salt & pepper and
-instead of mozz or Swiss, put about 1/4 square of American cheese inside the pepper and then a slice on top. Bake until melted and it was like a true philly but still healthy . SO. GOOD.
Thanks for the recipe!
Taylor Stinson says
I’m so happy you liked them Kellie!!! 🙂 Thanks for sharing!
Janis Merritt says
This sounds and looks wonderful, but this doesn’t sound like Keto with the carbs so high.
Vallof4 says
These were wonderful! We used flank steak seasoned with Montreal Steak seasoning and salted as directed in the recipe. Added a little hot sauce at the end and it’s was delicious!!
Mary Ann Bahler says
My husband loved these. Will be making them again in the very near future!
Kim says
How long would you cook these in the crockpot? And would you still cook the steak beforehand?
Taylor Stinson says
I would not try these in the crockpot, they would get really soggy!
Jono says
Hi Taylor, I do something similar with a fajita mix so I am very keen to try this. One question though, when you say sirloin steak, how many grams, approximately, would that be?
Taylor Stinson says
Hey Jono – unfortunately I can’t provide measurements of meat or poultry. If I had to guess, 4-6oz would work. I usually buy one steak that is 1-inch thick. Hope that helps!
Hannah says
I cant wait to try this! Quick question though…. for meal prepping these do you freeze half the batch until heated or leave it all in the fridge for the week?
Taylor Stinson says
Hey Hannah – I wouldn’t freeze these peppers. They should last 5 days in the fridge and you can reheat in the microwave 🙂
Jessica says
The video and pics are only showing 3 peppers. Is the recipe truly for 4 or 3? Also, it looks like it was seasoned with crushed red pepper yea or no?
Taylor Stinson says
For styling purposes, there are 3 peppers shown. The recipe calls for 4 peppers because otherwise there would be leftover ingredients (the steak, mushrooms, etc). Crushed red pepper was used as a garnish again for styling – this is optional.
Miranda says
For anyone who wanted a bit more flavor, I drizzled some Trader Joe’s Green Dragon hot sauce on mine and it goes amazingly with the recipe!
Taylor Stinson says
That sounds amazing Miranda!!! YUM!
