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.

Just wanted to let you know I tried this recipe tonight and it is delicious, did not miss the traditional bun at all in fact this was so much better! Will definitely make this again, thank you!

Brenda says
Why so many sugars?
I have to watch my sugars..
Why high carbs?
It looks delicious….just not sure about the sugars and carbs…
Taylor Stinson says
Hi Brenda – I provide estimated nutritional values as an added bonus to the recipes. I’m not a nutritionist so I could not tell you exactly where the carbs and sugars are coming from. I would guess from the veggies as vegetables naturally have some sugars (the bell peppers?) and carbs. 7g of sugar and 15g of carbs really are not very high for either, especially the carbs (only 5% of your daily serving size which is extremely low for a meal).
ashley says
How many peppers is one serving?
Taylor Stinson says
Hey Ashley! One pepper (or two pepper halves) is a serving ๐
Vida says
How do you store and how long do they last for meal prep purposes….looks amazing ๐
Taylor Stinson says
Thanks so much Vida!! You can store them in glass or plastic containers (one or two peppers is one serving size) and they should last 3-5 days in the fridge!
Shannon says
I cooked the peppers about 15 min in the oven so they were a tad softer and added some red pepper and onion sauce/ marinade i had in the fridge to the onions and mushrooms. Turned out great!
Taylor Stinson says
So happy you liked them Shannon! Cooking ahead of time is a great way to extract more flavour from the peppers if you have the time! ๐
Anibas says
Do they still sell tin foil? My store only sells aluminum foil. Will that work?
Taylor Stinson says
Yes, it’s the same thing!
someone says
It’s actually not the same thing. Tin foil was made of tin. Today aluminum foil is most commonly used because it doesn’t affect food flavor like tin foil did, and it is made from aluminum.
Bobbie says
I was so excited to make this and looked so yummy! But my husband and I were disappointed! It was very bland! I used salt pepper and even garlic. But, still no flavor.
Taylor Stinson says
Sorry you feel that way Bobbie! Sometimes all you need is a little bit of extra salt to season all the ingredients. I personally found these peppers full of flavour but to each their own!
Ashleigh says
Agree! These are okay but need more seasoning – garlic or steak sauce. Also, the green peppers need more than 15 minutes to soften them. Great concept though. Will be making them again with some flavour tweaks.
Taylor Stinson says
Glad you liked them Ashleigh! A little bit of extra salt may be all you need!
Julie says
Do you use 8 whole green peppers
Or do I want 8 halves?
Taylor Stinson says
Hey Julie – sorry it’s 4 green peppers and 8 halves! I’ve updated the recipe to reflect this ๐
Karly says
