How to Make Ground Beef Tacos with Pickled Red Onion

1. Quick-Pickle the Red Onion: Start by mixing 3 tablespoons vinegar, 3 tablespoons warm water, and a pinch of kosher salt in a small bowl. Add the sliced red onion and let it sit for at least 15 minutes. This quick-pickling process brightens the flavor.
2. Cook the Base: Heat 1 tablespoon olive oil in a large pan over medium heat. Once heated, add the finely diced white onion and sauté for about 5 minutes until soft and slightly golden.
3. Brown the Beef: Add 1 pound of lean ground beef to the pan, followed by 1 1/2 tablespoons taco seasoning and minced garlic. Cook until the beef is browned, breaking it apart with a spoon as it cooks.
4. Incorporate Tomato and Broth: Once the beef is browned, stir in 2 tablespoons tomato paste and ½ cup beef broth. Scrape up all the flavorful bits stuck to the pan for maximum taste. Let it simmer for 3-5 minutes until slightly thickened.
5. Add Beans: Fold in the drained and rinsed black beans, cooking for another 2-3 minutes until everything is heated through.
6. Season: Taste your mixture, adding extra salt and pepper if needed. This ensures each taco is perfectly seasoned.
7. Prepare the Toppings: While the beef mixture is simmering, prep your toppings. Halve the cherry tomatoes, shred the lettuce, and slice the jalapenos. Have your cheese and lime ready too.
8. Assemble the Tacos: Take your warm tortillas—either flour or corn—and fill them with the beef and bean mixture. Top generously with cherry tomatoes, shredded romaine lettuce, quick-pickled red onion, and an even sprinkle of shredded cheese. Finish each taco with a wedge of lime and sliced jalapenos if desired.

Storing & Reheating

To store, keep any leftover beef mixture in an airtight container in the fridge for up to 4 days. The pickled onions can stay in the fridge for about two weeks if you don’t finish them all. If you want to freeze the beef mixture, place it in a freezer-safe container or bag and it will last for up to 3 months. When ready to enjoy, thaw in the refrigerator overnight and reheat on the stove over low heat until warmed through, adding a splash more broth if needed to maintain moisture. Just note that the pickled onions will lose some crunch when reheated.

Enjoying these Ground Beef Tacos with Pickled Red Onion is not just about the taste; it’s about the experience of making something delightful for you and your loved ones. Each ingredient plays a role, balancing savory with bright and fresh flavors. There’s no right or wrong when it comes to assembling your tacos—let your creativity shine! So why not gather your favorite people and make these tacos part of your next dinner gathering? The joy they bring is something you’ll want to share time and again.
