Recipe tips and variations
Want to mix things up? Here are some tasty variations and helpful tips for making these stuffed peppers your way.
- Switch up the protein: Use ground beef, ground turkey, or even thinly sliced chicken instead of steak.
- Cheese options: Provolone is classic, but mozzarella, cheddar, or even a cheese blend will work well.
- Make it vegetarian: Swap steak for sautรฉed portobello mushrooms or crumbled tofu for a plant-based option.

- Meal prep friendly: Store in the fridge up to 4 days or freeze individually for grab-and-bake dinners.
Frequently asked questions
What cut of beef works best for Philly cheesesteak?
Ribeye is the traditional choice for Philly cheesesteak, but sirloin or flank steak also work well and are often more budget-friendly. The key is slicing it super thin across the grain so it stays tender.
How can I add healthy carbs to this recipe?
Serve the peppers with brown rice, quinoa, or roasted sweet potatoes for a balanced meal.
Will the peppers get soggy?
Not if you pre-bake them lightly and avoid overfilling with ingredients that hold a lot of liquid. You can also place the peppers on a baking rack over the dish so any moisture drips off.

What to serve with this dish
Here are some of my favourite ways to serve these stuffed peppers:
- Pair with a light caesar Salad for freshness and crunch or light veggie salad like Mason Jar Salad
- Serve with crispy Air Fryer Sweet Potato Fries, Crispiest Air Fryer Zucchini Fries or Crispy Green Bean Fries.
- Warm up with a bowl of Roasted Tomato Soup for a cozy combo.
How to store and reheat
Make ahead: Assemble the stuffed peppers up to the point of baking and store them in the fridge for up to 2 days.
Store: Leftovers will keep in an airtight container in the fridge for up to 4 days.
Reheat: Warm in the oven at 350 F for 10-15 minutes or microwave for 1-2 minutes until heated through.
Freeze and reheat from frozen: Freeze in airtight containers or freezer bags for up to 3 months. Bake from frozen at 375 F for 25-30 minutes until hot all the way through.

Comments & Reviews
Lisa says
Iโm excited about the recipe I will be enjoying these cooked for the final process in the air fryer, since itโs too hot for the oven. I will cook the stuffed peppers (Iโm following your yummy recipe) at 390 degrees for 10 minutes. I canโt wait. I just know they will be delicious. Thanks๐
Taylor Stinson says
Ooooh interesting that you cooked them in the Airfryer!!! Hope they turned out well for you ๐
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 lawryโs 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!!! ๐ 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 itโs 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 ๐
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 Joeโs Green Dragon hot sauce on mine and it goes amazingly with the recipe!
Taylor Stinson says
That sounds amazing Miranda!!! YUM!
