Key Ingredients
Flour Tortillas
Use burrito-size flour tortillas—soft, flexible, and large enough to hold a generous filling. Fresh tortillas fold and crisp beautifully without cracking.
Monterey Jack Cheese
Shred it yourself for the best melt and mild tang. It’s creamy, stretchy, and balances perfectly with steak.
Mozzarella Cheese
This cheese brings the ultimate pull. Its creamy texture melts into every bite, giving that signature cheesy stretch when you tear a slice apart.
Skirt Steak
Rich and flavorful, skirt steak cooks fast and delivers juicy, beefy bites. Cube it into small pieces for even cooking. Sirloin or ribeye also work beautifully.
Onion
A medium yellow or white onion adds sweetness and depth. Dice it fine so it caramelizes evenly.
Seasonings
- Kosher salt: Enhances every flavor.
- Black pepper: Adds a subtle kick.
- Onion powder: Intensifies the savory note.
Vegetable Oil
A light coating of oil on the griddle prevents sticking and ensures the steak and tortillas crisp evenly.
Step-by-Step Instructions
Step 1: Preheat the Blackstone
Set your Blackstone griddle to medium-high heat (about 400°F). Brush a thin layer of vegetable oil over the surface. You want it hot enough to sear the meat quickly without drying it out.
Step 2: Sear the Steak and Onions
Add diced steak and onions directly onto the oiled griddle. Season with salt, pepper, and onion powder. Spread them out so they get that perfect sear instead of steaming. Cook for 4–8 minutes, flipping occasionally until the steak is browned and the onions turn golden and soft.
Step 3: Clear Space and Lower Heat
Once cooked, move the steak and onion mixture to one side of the griddle and reduce the heat slightly. This ensures your tortillas won’t burn when toasting.
Step 4: Assemble the Quesadillas
Lay four tortillas flat on the cooler side of the grill. Sprinkle half of your shredded cheese (both mozzarella and Monterey Jack) evenly across each tortilla. Spoon the hot steak and onion mixture over the cheese, then top with the remaining cheese.
Step 5: Fold and Toast
Fold each tortilla in half, pressing gently with a spatula to hold the filling in place. Let them toast for about 2 minutes on one side until golden brown and crisp.
Step 6: Flip and Finish
Flip each quesadilla carefully with a wide spatula. Toast the other side for another 1–2 minutes until both sides are perfectly golden and the cheese inside is melted and bubbly.
Step 7: Slice and Serve
Transfer to a cutting board, let rest for a minute, and slice into triangles using a pizza cutter or sharp knife. Serve immediately while hot and crispy.
Pro Tips for the Perfect Quesadilla
- Shred your cheese fresh: Pre-shredded cheese has anti-caking agents that prevent smooth melting.
- Don’t overcrowd the grill: Space helps your steak sear properly for maximum flavor.
- Watch the heat: Keep an eye on tortillas; they can go from golden to burnt in seconds.
- Rest the steak: If pre-cooked, let it rest a few minutes before assembling to retain juices.
- Double up: If feeding a crowd, keep finished quesadillas warm in a 200°F oven until serving.
Ingredient Swaps and Variations
- No skirt steak? Substitute with sirloin, ribeye, or leftover grilled beef.
- Dairy-free version: Use vegan cheese and gluten-free tortillas.
- Add-ins: Cooked bell peppers, jalapeños, or mushrooms add extra texture and flavor.
- Cheese swap: Try cheddar, Colby Jack, or pepper jack for a spicier twist.
- Vegetarian option: Replace steak with grilled portobello mushrooms or roasted peppers.
Serving Suggestions
These Steak Cheese Quesadillas pair perfectly with:
- Guacamole: Adds creamy freshness.
- Salsa or Pico de Gallo: Brightens each bite.
- Sour Cream: Adds a cool contrast to the warm quesadilla.
- Rice and Black Beans: Turn it into a full Tex-Mex meal.
- Fresh Lime: A quick squeeze enhances all the flavors.
For a fun spread, create a quesadilla bar with different dips—queso, chipotle mayo, and salsa verde. Everyone can mix and match their favorites.
Storage and Reheating
If you somehow have leftovers (rare, but possible!), here’s how to keep them tasty:
- Refrigerate: Store in an airtight container for up to 3 days.
- Reheat: Warm on the Blackstone or in a skillet over medium heat until crisp again. Avoid microwaving, as it makes them soggy.
- Freeze: Wrap slices individually in foil or parchment, then store in freezer bags. Reheat from frozen in the oven at 375°F until hot and crunchy.
Tips for Blackstone Cooking
- Always preheat your griddle for even cooking.
- Oil lightly—too much and the tortillas will turn greasy.
- Use two heat zones: One side for searing, one for toasting.
- Keep tools handy: A wide spatula and scraper make flipping easy and clean.
Frequently Asked Questions
What steak cut works best for quesadillas?
Skirt steak is the best choice because it cooks quickly and stays juicy. Sirloin or ribeye are great alternatives if you prefer thicker cuts.
Can I use other cheeses instead of mozzarella and Monterey Jack?
Absolutely. Cheddar, Colby Jack, or pepper jack are flavorful substitutes that melt beautifully.
How do I prevent the tortillas from burning?
Keep your heat at medium. Watch closely and flip once they’re golden brown to avoid scorching.
What toppings go best with steak quesadillas?
Fresh salsa, guacamole, sour cream, or a squeeze of lime bring brightness and balance to the rich filling.
Should I cook the steak and onions beforehand?
Yes. Pre-cooking ensures both are tender, flavorful, and ready to melt together inside the tortillas.
