Ingredients

Ground Beef (1 lb / 450 g): Provides rich, hearty protein base, browned and seasoned for bold taco flavor.
Small Onion, finely diced: Adds subtle sweetness and texture complementing the beef.
Garlic Cloves (2), minced: Infuses the meat mixture with savory aroma and depth.
Taco Seasoning Packet (or homemade mix): A blend of spices that delivers classic Mexican taco taste.
Tomato Sauce or Salsa (⅔ cup): Moistens the filling and adds tangy, slightly spicy notes.
Salt & Pepper: Balances and enhances overall seasoning to taste.
Hard Taco Shells (8 shells): Crisp and sturdy shells to hold the savory, cheesy filling.
Shredded Cheese (2 cups): Cheddar, Monterey Jack, or Mexican blend melts perfectly for gooey topping.
Shredded Lettuce (1 cup): Fresh, light crunch to contrast warm taco filling.
Diced Tomatoes (½ cup): Juicy, vibrant topping that adds freshness.
Diced Red Onion (¼ cup): Sharp and colorful garnish for added depth.
Chopped Cilantro (2 tablespoons, optional): Bright herbal note to elevate flavors.
Sour Cream (optional): Creamy, cooling element for serving.
Guacamole (optional): Adds rich, buttery texture and flavor.
Jalapeño Slices (optional): Kick up the heat with spicy peppers if desired.
Hot Sauce (optional): Extra spice for adventurous palates.

Instructions

Preheat the Oven: Set your oven to 400°F (200°C) and place taco shells upright in a baking dish. This ensures the shells stay crisp during baking and makes filling easier.
Cook the Beef and Aromatics: In a skillet over medium heat, cook ground beef with finely diced onion until fully browned and fragrant. Drain fat to avoid greasiness. Then add minced garlic and taco seasoning, stirring to coat and release spices for one minute.
Add Tomato Sauce and Simmer: Pour in tomato sauce or salsa and reduce heat to low, letting the mixture simmer for 5 minutes. This deepens flavor and keeps the meat juicy while binding the seasoning well.
Assemble the Tacos: Evenly spoon the beef mixture into the prepared taco shells. Top each with a generous amount of shredded cheese to ensure a gooey, melted topping once baked.
Bake Until Golden and Melty: Place the baking dish in the preheated oven and bake for 10–15 minutes. The cheese will melt beautifully and the taco shells will turn golden and crispy, enhancing texture.
Add Fresh Toppings and Serve: Remove tacos from the oven and immediately top with shredded lettuce, diced tomatoes, red onion, and cilantro for freshness. Serve warm with optional sour cream, guacamole, jalapeños, or hot sauce for extra flair.

FAQs

Can I use soft tortillas instead of hard taco shells?: Yes, but the baking time and method would differ. Soft tortillas can be warmed in the oven or skillet but won’t achieve the same crispy texture.

Can I prepare these tacos ahead of time?: You can cook and store the beef filling in advance and assemble tacos just before baking to maintain shell crispness.
How spicy is this dish?: Spice level depends on the taco seasoning and optional jalapeños or hot sauce. Adjust to taste for mild or spicy versions.
Can I freeze the cooked beef filling?: Yes, cool completely and freeze in an airtight container for up to 3 months. Thaw in the fridge and reheat before assembling tacos.
What cheese works best for these tacos?: Mexican cheese blends, cheddar, and Monterey Jack melt well and provide good flavor. Feel free to experiment with your favorites.
Are these tacos gluten free?: Yes, using hard taco shells labeled gluten free and checking seasoning ingredients will keep this dish gluten free.
