Ingredients

For the Beef Filling

  • 1 pound ground beef 80/20
  • 1/2 cup white onion diced
  • 2 tablespoons tomato paste
  • 1 packet taco seasoning
  • 1/4 cup water

For Assembly

  • avocado oil spray as needed
  • 8 flour tortillas 8-inch
  • 2 cups Mexican cheese blend shredded

For the Jalapeño Sour Cream

  • 1/2 cup sour cream
  • 2 tablespoons pickled jalapeño brine
  • 1/4 cup pickled jalapeños

Optional Toppings

  • shredded lettuce
  • diced tomato
  • fresh cilantro
  • fresh jalapeño sliced
  • pickled red onions
  • lime wedges

Instructions

Brown the Beef

  • Heat a large skillet over medium heat. Add ground beef and break into small crumbles. Cook until halfway browned, 4-5 minutes. Add the diced onion. Continue cooking until beef is fully browned and onion is soft, 3-4 more minutes. Drain excess grease.

Season the Filling

  • Sprinkle taco seasoning over the beef and stir to coat. Push beef to the edges of the pan. Add tomato paste to the center and cook 30 seconds until it darkens. Stir into the beef. Pour in water and simmer 2 minutes until the sauce thickens.

Prep the Baking Sheets

  • Preheat oven to 400°F. Spray two large baking sheets with avocado oil spray. Lay tortillas flat in a single layer without overlapping.

Assemble

  • Sprinkle a small amount of cheese on each tortilla. Spoon beef over the cheese. Top with the remaining cheese.

Bake

  • Bake 12-15 minutes until cheese is fully melted and tortilla edges are golden brown. Watch closely in the final 2 minutes.

Make the Sauce

  • While tacos bake, blend sour cream, pickled jalapeño brine, and pickled jalapeños until smooth.

Fold and Serve

  • Working immediately while cheese is still hot, fold each taco in half and press with a spatula to seal. Drizzle with jalapeño sour cream. Add toppings. Serve immediately.

Notes

  • Bake only what you plan to eat. These do not reheat well once folded and topped.
  • Fold within 2 minutes of pulling from the oven. Cheese sets quickly as it cools.
  • To reheat leftover shells: 350°F oven on a wire rack, 8-10 minutes.
  • Jalapeño sour cream keeps refrigerated up to 5 days. Beef filling keeps up to 3 days.
