Step 1: Preheat Blackstone & Oil Surface
Set your Blackstone griddle to medium-high heat (around 400°F) .
Spread vegetable oil evenly across the cooking surface—use a silicone brush for best coverage.
Step 2: Sear the Steak & Caramelize Onions
Add diced steak and onions to the griddle in an even layer.
Sprinkle with onion powder, salt, and pepper .
Sauté for 4–8 minutes , flipping occasionally, until steak is browned and cooked through and onions are golden and soft.
Push steak and onions to one side of the griddle while proceeding.
Step 3: Assemble the Quesadillas
On the cleared area of the griddle, lay out flour tortillas .
Layer mozzarella and Monterey Jack cheese over half of each tortilla.
Add a generous portion of steak and onion mixture over the cheese.
Top with more cheese to ensure a gooey center.
Step 4: Fold & Press Like a Pro
Using a spatula, gently fold each tortilla in half to form a half-moon shape .
Press lightly with the back of the spatula to flatten slightly and encourage even melting.
Step 5: Grill Until Golden
Cook each quesadilla for 1–2 minutes per side , or until both sides are golden and crisp.
Watch closely—tortillas brown quickly on a hot griddle.
Step 6: Slice & Serve Hot
Transfer to a cutting board and let rest for 2–3 minutes to set the filling.
Cut into 3–4 wedges per quesadilla.
Serve immediately with:
- Guacamole, sour cream, or salsa
- A drizzle of hot sauce or lime crema
Each bite brings together:
- Juicy, seasoned steak pockets
- Sweet, golden caramelized onions
- Stretchy, golden cheese layers
- And that classic tortilla crunch
