Pepper steak quesadillas are the perfect mashup for nights when I crave something bold but easy. Sizzling steak strips cooked with bell peppers and onions get smothered in a sweet soy sauce, then tucked inside warm tortillas with gooey cheese. This meal always disappears fast at family gatherings, and it beats takeout every time.
I whipped these up one Super Bowl Sunday and could barely get them off the cutting board before my friends snagged them. Now I get requests for pepper steak quesadillas at every game day.
Ingredients
- Flat iron steak or skirt steak: look for marbling and slice against the grain for tender bites
- Salt and pepper: bring out the meaty flavors while a little garlic adds punch
- Green bell pepper: for color and crunch pick firm glossy peppers
- Yellow bell pepper: for sweetness blends perfectly with the other peppers
- Red bell pepper: brightens everything with its vibrant hue
- White onion: becomes sweet and mellow when sautéed until soft
- Soy sauce: use a good quality for deep umami
- Brown sugar: adds perfect caramel richness look for dark brown for the best flavor
- Oyster sauce: deepens savory notes a simple spoonful goes a long way
- Rice wine vinegar: balances sweetness with a gentle tang
- Sesame oil: toasty aroma and flavor always use toasted varieties for more complexity
- Garlic paste: mixes evenly into sauces and seasons the steak intensely
- Ginger paste: fresh zing without the need for peeling and grating
- Red pepper flakes: give a gentle spicy kick add more or less to taste
- Large tortillas: sturdy flour tortillas are best for holding everything in
- Mexican melting cheese: Oaxaca or Chihuahua melt beautifully and stretch for miles
- Chipotle mayo or sour cream: pick your favorite for extra sauciness
- Avocado oil: excellent for high heat cooking and keeping things from sticking
Step-by-Step Instructions
- Prep the Veggies:
- Chop the bell peppers and onion evenly so they cook at the same rate. Heat your griddle over medium and cook the peppers and onion for about ten minutes. Wait until they are soft and translucent for a sweet base
- Cook the Steak:
- Season the steak strips with salt pepper and garlic. Spread them in an even layer on the griddle and cook for six to eight minutes. Flip occasionally so all slices brown evenly for the best crust
- Mix the Sauce:
- Whisk together the soy sauce brown sugar oyster sauce rice wine vinegar sesame oil garlic paste ginger paste red pepper flakes and water in a bowl. Stir until smooth and taste for balance
- Combine Steak Veggies and Sauce:
- Return the sautéed peppers and onions to the griddle with the steak. Pour in the sauce and toss to coat every piece. Let this cook several minutes until the sauce thickens and everything caramelizes together
- Clean the Griddle and Add Oil:
- With a little water scrape off browned bits and wipe the griddle. Add a drizzle of avocado oil so the quesadillas get a crisp crust
- Assemble the Quesadillas:
- Lay a tortilla on the hot griddle. Warm it for sixty to ninety seconds then flip it. Sprinkle a layer of cheese on one half add a scoop of pepper steak mix drizzle on chipotle mayo or sour cream then a little more cheese. Fold the tortilla over everything
- Toast and Serve:
- Cook each folded quesadilla until golden brown on both sides. Press gently for extra crispness. Slice into wedges and serve immediately for maximum melt and crunch

I always use the sweetest red bell peppers I can find since their flavor deepens when caramelized on a hot griddle. The first time my mom helped me make these we doubled the recipe and still had none left by the end of dinner. It is a true crowd-pleaser and the memories are always as good as the food.
Storage Tips
Once cooled store leftover quesadillas in an airtight container in the fridge for up to three days. For longer storage wrap individually and freeze. To reheat simply pop them back on a hot skillet or in a toaster oven which brings back that irresistible crispiness. I never recommend microwaving since it can make them soft but my kids are known to snatch the cold leftovers straight from the fridge
Ingredient Substitutions
No flat iron steak Use chicken strips or portobello mushrooms for a just as juicy filling. If you do not have brown sugar honey is a great swap. Skip oyster sauce if needed and add a splash more soy sauce and a bit of hoisin for depth. Any good melting cheese will work but for extra stretch try Oaxaca or Monterey Jack

Serving Suggestions
Slice into triangles and serve as a main dish with guacamole and salsa. For appetizers cut smaller wedges and plate with extra chipotle mayo for dipping. These are at home on any party spread or as a hearty dinner with a green salad on the side
Recipe Roots
Pepper steak has roots in both Chinese stir fry and American diner classics. The quesadilla twist takes that popular flavor combo and wraps it up in a cheesy Mexican staple. This fusion recipe is a regular at our house for game night potlucks and quick weeknight meals
Recipe FAQs
