The cooking process explained

Making Oven-Baked Cheesy Tacos is a breeze. Start by preheating your oven and preparing your taco shells to hold all that savory goodness.

What you’ll need

To create these delightful tacos, gather the following ingredients:

  • 1 lb (450 g) ground beef
  • 1 small onion, finely diced
  • 2 cloves garlic, minced
  • 1 packet taco seasoning
  • 2/3 cup tomato sauce or salsa
  • Salt and pepper to taste
  • 8 hard taco shells
  • 2 cups shredded cheese (choose from cheddar, Monterey Jack, or a Mexican blend)
  • 1 cup shredded lettuce
  • 1/2 cup diced tomatoes
  • 1/4 cup diced red onion
  • 2 tablespoons chopped cilantro (optional)
  • Sour cream (optional)
  • Guacamole (optional)
  • Jalapeño slices (optional)
  • Hot sauce (optional)

Feel free to swap the ground beef for turkey or a plant-based alternative if you prefer a different protein!

Directions to follow

  1. Preheat your oven to 400°F (200°C). Arrange the hard taco shells upright in a baking dish.
  2. In a skillet over medium heat, toss in the ground beef and diced onion. Cook until the beef is browned and the onion is translucent.
  3. Drain any excess fat. Return the skillet to the heat, add in the minced garlic and taco seasoning, cooking for about 1 minute to release the flavors.
  4. Stir in the tomato sauce or salsa, and allow it to simmer for 4 to 5 minutes.
  5. Spoon the seasoned beef mixture into each taco shell, generously topping with shredded cheese.
  6. Bake in the oven for 10 to 15 minutes, until the cheese is bubbly and the shells are crispy.
  7. Remove from the oven and add your toppings: lettuce, diced tomatoes, red onion, and cilantro.

Best ways to enjoy it

These Oven-Baked Cheesy Tacos are fabulous just as they are, but you can easily elevate your serving experience. Consider pairing them with a side of Mexican rice or refried beans for a complete meal. For a refreshing touch, serve with a simple avocado salad or a bowl of zesty corn salsa.

Storage and reheating tips

If you find yourself with any leftovers (though I doubt you will), storing your cheesy tacos is straightforward. Keep them in an airtight container in the refrigerator for up to three days. To reheat, place them in a preheated oven at 350°F (175°C) for about 10 minutes until warmed through. If you want to keep them longer, the cooked filling can be frozen for up to three months. Just be sure to separate the shells from the filling to maintain their crunch.

Pro chef tips

  • To enhance the flavor, you can add some chopped bell peppers or black beans into the beef mixture.
  • If you want a spicier kick, consider mixing in diced jalapeños with the beef.
  • For an extra cheesy experience, layer some cheese beneath the taco filling before topping with more cheese.

Recipe variations

There are countless ways to switch up these Oven-Baked Cheesy Tacos. Try using shredded chicken or a meat substitute for a different protein option. For a vegetarian take, fill the shells with seasoned beans, veggies, and cheese. You could even experiment with various sauces—try a spicy chipotle sauce for an exciting twist.
