📃 Why It Works

  • This recipe is make-ahead friendly: cook the steak and mushrooms in advance and reheat or assemble when needed.
  • Small 4-inch tortillas create perfect hand-sized quesadillas that are easy to serve and eat.
  • Simple seasoning keeps the flavors familiar and kid-friendly while still tasting hearty.
  • It’s easy to customize: add peppers, onions, or extra vegetables and pair with dips for more variety.

🥩 The Best Steak for Quesadillas

Top sirloin, flank, or skirt steak are affordable, flavorful choices that slice well for quesadillas. If you prefer a richer, more marbled cut and budget allows, ribeye or Angus will be more tender.

For convenience or a smaller budget, use shaved beef or thick-sliced roast beef from the deli. Leftover steak from fajitas, carne asada, or grilled steak also works beautifully.

🛒 Ingredients and Notes

Ingredients for Mexican baked tortillas with beef, portabellas, and cheese on a counter.
  • Tortillas: Ten 4-inch flour tortillas (folded in half for 10 mini quesadillas). For smaller bites, cut each in half after cooking or use 8-inch tortillas and slice into wedges.
  • Mushrooms: 8 oz baby bella (cremini) mushrooms, sliced and sautéed with garlic. Substitute shiitake, button, or other mushrooms if preferred.
  • Cheese: Shredded Mexican blend is ideal, but Monterey Jack, mozzarella, or Oaxaca are good alternatives. Shredded cheese melts faster than slices.
  • Meat: About 1 pound top sirloin (or flank/skirt), trimmed and thinly sliced. Season simply with salt and pepper.
  • Other: Butter for mushrooms, cooking spray or a light oil for toasting, and salsa for dipping.

🔪 Instructions

Beef steak strips in a cast-iron skilled, sliced mushrooms in a skillet, and a person assembling quesadillas in steps.
  1. Prep the steak: Slice the meat against the grain into thin strips (about 1/4-inch). Season with salt and pepper. Heat a large cast-iron or nonstick skillet over medium-high heat with a light coating of oil or cooking spray. Sear the beef strips in batches to avoid overcrowding, 1–2 minutes per side, until cooked to your liking. Transfer to a bowl.
  2. Cook the mushrooms: In the same skillet, melt 1 tablespoon butter. Add minced garlic and the sliced mushrooms. Sauté over medium-high heat until the mushrooms brown and their liquid evaporates. Combine the mushrooms with the cooked steak.
  3. Assemble and toast: Wipe the skillet clean and reduce heat to medium. Sprinkle about 2 teaspoons of shredded cheese over half of each tortilla, divide the steak-and-mushroom mixture among tortillas (placing it on one half), then sprinkle with more cheese and fold the tortilla in half. Lightly coat both sides with cooking spray or brush with a little oil. Toast each quesadilla 1–2 minutes per side until golden and the cheese is melted. Use a spatula to press and flip carefully. Repeat with remaining quesadillas.
  4. Serve: Cut if desired and serve hot with salsa, guacamole, or sour cream for dipping.

👉 Variations

  • Add sautéed onions and bell peppers to make steak-fajita style quesadillas.
  • Season the steak with taco seasoning or a pinch of chili powder for more Mexican spice.
  • Add sliced jalapeños or poblanos for heat, or top with pickled peppers for brightness.
  • Swap flour tortillas for whole wheat, or use larger tortillas and cut into wedges for sharing.
  • Use leftover grilled carne asada or chimichurri steak for extra flavor.

  • To slice steak easily, chill in the freezer for 10–15 minutes before cutting or use a very sharp knife.
  • Slice against the grain for the most tender bites.
  • For bite-sized portions, cut cooked mini quesadillas in half or switch to larger tortillas and slice into wedges.
  • Double the batch for larger gatherings; these disappear fast.
