Ingredients You’ll Need
- 1 pound ground beef (80/20): This fat-to-lean ratio is ideal for juicy tacos. Ground turkey or chicken can be used for a leaner option.
- 1/2 cup white onion (diced): Adds sweetness and depth to the beef. Yellow or red onions work too!
- 2 tablespoons tomato paste: Enhances the beef’s flavor and provides a rich color. You can substitute with fresh tomatoes, but adjust the liquid.
- 1 packet taco seasoning: A flavor powerhouse that makes seasoning effortless. You can also mix your own with chili powder, cumin, and garlic.
- 1/4 cup water: Helps to combine flavors and make a juicy filling.
- avocado oil spray (as needed): For a light coating on the baking sheets. Olive oil spray is a feasible alternative.
- 8 flour tortillas (8-inch): These provide a soft wrap; corn tortillas will work for a gluten-free option.
- 2 cups Mexican cheese blend (shredded): Melts beautifully for that gooey texture; feel free to mix with cheddar or Monterey Jack.
- 1/2 cup sour cream: The creamy base for the sauce; Greek yogurt is a healthier substitute.
- 2 tablespoons pickled jalapeño brine: Adds kick and tang to the creamy sauce. Substitute with other pickled peppers if desired.
- 1/4 cup pickled jalapeños: Provides a delightful crunch and heat; fresh jalapeños could be used for less tang.
- shredded lettuce: For crunch and freshness.
- diced tomato: Adds freshness and color.
- fresh cilantro: Brightens up the flavors; optional if you’re not a fan.
- fresh jalapeño (sliced): Can be added for extra spice on top.
- pickled red onions: For added tanginess and beautiful color.
- lime wedges: A squeeze of lime zest elevates the flavors in every bite.
How to Make Baked Beef Tacos with Jalapeño Sour Cream
- Brown the Beef: Heat a large skillet over medium heat. Add 1 pound of ground beef and break it into small crumbles. Cook until halfway browned, which should take about 4-5 minutes.
- Once the beef is beginning to brown, add 1/2 cup of diced white onion. Continue cooking until the beef is fully browned and the onion is soft, roughly 3-4 more minutes.
- Next, drain any excess grease from the skillet.
- Season the Filling: Sprinkle one packet of taco seasoning over the beef. Stir well to coat the meat evenly. Push the beef mixture to the edges of the pan.
- In the center of the skillet, add 2 tablespoons of tomato paste and allow it to cook for about 30 seconds until it darkens slightly. Stir this into the beef mixture.
- Pour in 1/4 cup of water and simmer for 2 minutes. This allows the sauce to thicken and the flavors to meld beautifully.
- Prep the Baking Sheets: Preheat your oven to 400°F. While that heats, spray two large baking sheets lightly with avocado oil spray.
- Lay the 8 flour tortillas flat on the baking sheets in a single layer, ensuring they do not overlap.
- Assemble: On each tortilla, sprinkle a small amount of shredded Mexican cheese. Then add a spoonful of the beef mixture over the cheese. Top with the remaining cheese.
- Bake: Place the baking sheets in the oven and bake for 12-15 minutes, or until the cheese is perfectly melted and the edges of the tortillas are golden brown. Keep an eye on them in the last couple of minutes to avoid over-browning.
- Make the Sauce: While the tacos bake, blend 1/2 cup of sour cream, 2 tablespoons of pickled jalapeño brine, and 1/4 cup of pickled jalapeños in a blender until smooth and creamy.
- Serve: Immediately after baking, fold each taco in half and press gently with a spatula to seal the edges while the cheese is still hot. Drizzle with your jalapeño sour cream sauce and add your favorite toppings like shredded lettuce, diced tomato, fresh cilantro, sliced fresh jalapeños, and pickled red onions. Serve with lime wedges for an extra squeeze of freshness.
Storing & Reheating
Store any leftovers at room temperature for up to 2 hours or refrigerate in an airtight container for up to 3 days. If you decide to freeze them, wrap each taco separately in plastic wrap and place them in a freezer bag; they’ll keep well for up to 3 months. To reheat, pop them in the oven at 350°F for about 10-15 minutes or until heated through. Be aware that while freezing and reheating may alter the tortilla’s original texture, a brief time in the oven can help crisp them up again.
Chef’s Helpful Tips
- Ensure the ground beef is well-browned for best flavor—don’t rush this step!
- For extra crunch, toast the tortillas in a dry skillet for a minute on each side before assembly.
- If you’re short on time, use pre-shredded cheese and store-bought taco seasoning.
- Experiment with toppings; add avocado slices or corn for a fun twist!
- Prepare everything ahead of time, and keep the assembled tacos in the fridge until you’re ready to bake—they work great as a make-ahead meal!
