Sheet Pan Quesadillas: Quick Oven-Baked Mexican Dinner

Sheet Pan Quesadilla Ingredients

The ingredient list is short and relies mostly on pantry staples. That’s part of what makes this meal so convenient—chances are you already have what you need.

GROUND BEEF: I brown 1 pound of ground beef and season it with homemade taco seasoning, but shredded rotisserie chicken or no meat at all work great too. You can split the pan into sections to make different fillings.

WATER: used to turn the taco seasoning into a light sauce for the meat.

TACO SEASONING: homemade or store-bought will work.

YELLOW ONION: diced. Sweet or red onion are fine if you prefer.

BELL PEPPER: any color; diced.

BLACK BEANS: drained and rinsed. Swap or omit as desired.

SHREDDED CHEESE: a Mexican blend or your favorite shredded cheese, divided.

SALSA: store-bought or homemade; try fruity salsas for a twist.

FLOUR TORTILLAS: burrito-size works best to cover the pan.

QUESADILLA SAUCE: optional but highly recommended for serving and mixing into the filling.

Homemade Taco Seasoning

Making taco seasoning at home is quick and inexpensive if you already have basic spices on hand. A homemade mix tastes brighter than most packets and is gluten- and dairy-free, should you need a Substitute in other recipes.

The Quesadilla Sauce

Quesadilla sauce adds a creamy, slightly spicy flavor that we love. It combines mayonnaise, sour cream, and spices for a tangy finish. I mix some into the filling and serve extra for dipping. It’s easy to make in a blender and only takes a few minutes.

How to Make Sheet Pan Quesadillas

Preheat the oven to 425ºF (218ºC). Spray a large baking sheet with nonstick spray or line with parchment paper and set it aside.

Step 1: Brown the Meat

Heat a skillet over medium and add the ground beef. Cook, breaking it up with a spoon, until no pink remains. Do not drain—the fat will help cook the vegetables. Add 1/3 cup water and 3 tablespoons taco seasoning, stir to combine, and simmer 2–3 minutes to thicken. Spoon the meat (leaving behind excess fat) into a bowl and set aside.

Step 2: Cook the Vegetables

In the same skillet, sauté diced onion and bell pepper in the reserved fat (or a splash of olive oil) for about 5 minutes until softened. Return the cooked meat to the pan, add drained black beans and salsa, stir to combine, then remove from heat.

Step 3: Place the Tortillas

Arrange six burrito-size flour tortillas around the edges of the prepared baking sheet, overlapping so the pan is mostly covered. Place one tortilla in the center to fill the gap. Some overhang is expected and will be folded over later.

Step 4: Layer the Filling

Sprinkle half the shredded cheese (about 1 cup) evenly over the tortillas inside the pan. Spread the meat and vegetable mixture on top, smoothing it to the edges. If using quesadilla sauce, drizzle some over the filling—consider reserving sauce on one half for kids if desired. Top with the remaining cheese.

Step 5: Bake Quesadillas

Place a second baking sheet on top to press the edges together. Bake both sheets for 20 minutes, remove the top sheet, and bake an additional 5 minutes to crisp and brown the top. Let cool slightly, then cut into squares.

Make Ahead and Freezing

You can assemble the unbaked sheet pan quesadillas up to 12 hours in advance and refrigerate until ready to bake. For longer storage, freeze them unbaked for up to 3 months. Thaw in the refrigerator before baking, or bake from frozen following the same times with additional time if needed.

• 1 pound (454g) ground beef
• ⅓ cup (80mL) water
• 3 Tablespoons (30g) homemade taco seasoning
• 1 yellow onion, diced
• 1 bell pepper, diced
• 1 15-ounce can (425g) black beans, drained and rinsed
• 2 cups (227g) shredded cheese, divided
• ½ cup (120g) salsa
• 8 large flour tortillas, burrito size
• ½ to 1 cup (120–240mL) quesadilla sauce (optional)

• Preheat the oven to 425ºF (218ºC). Spray a large baking sheet with nonstick spray. Set aside.
• In a large skillet over medium heat, cook the ground beef until completely browned (do not drain). Add the water and taco seasoning, mix well, and cook another 2–3 minutes. Spoon the meat into a medium bowl and set aside.
• In the same skillet, use the reserved fat (or a little olive oil) to cook the diced onion and bell pepper until softened, about 5 minutes. Add the cooked meat and black beans, stir to combine, then remove from heat.
• Place 6 tortillas around the edges of the baking sheet, overlapping and allowing them to hang over the edge. Place 1 tortilla in the center to fill the gap.
• Sprinkle half the shredded cheese (about 1 cup) evenly over the tortillas inside the pan. Spread the meat/vegetable/bean mixture evenly, then add salsa and pour quesadilla sauce if using. Top with the remaining cheese.
• Place the final tortilla over the center and fold the overhanging edges toward the middle so the filling is enclosed.
• Place another baking sheet on top to press the edges together. Bake the stacked sheets for 20 minutes, remove the top sheet, then bake an additional 5 minutes to brown and crisp the top.
• Remove from the oven, allow to cool slightly, then cut into squares and serve with extra quesadilla sauce, salsa, or sour cream. Store leftovers tightly covered in the refrigerator up to 3 days. Freeze unbaked or baked quesadillas up to 3 months; reheat from frozen in an air fryer at 400ºF for 10–15 minutes.
