Savory and a little bit spicy these slow cooker Korean ground beef tacos always hit the spot after a long day. The beef becomes extra flavorful as it cooks and is perfectly balanced by a fast homemade pickled cucumber. Great for busy days or when you want something different but simple.
I stumbled across this method one summer when craving bulgogi flavors without a grill and my family devoured every last taco. Now it is a go to for both gatherings and cozy nights.
Ingredients
- Ground beef: go for 80 20 blend for juicy texture and flavor
- Soy sauce: low sodium is best to avoid salty overload
- Brown sugar: gives classic Korean style sweetness and balances the sauce
- Garlic: fresh and generously minced for punchy aroma
- Freshly grated ginger: delivers warmth and complexity
- Gochugaru: Korean chili flakes for smoky heat but not overpowering
- Sesame oil: rich nutty undertone crucial for real Korean flavor
- Green onions: stirred in at the end for freshness and color
- Corn or flour tortillas: warm and soft hold all the fillings
- Cucumber: pickled quickly to cut the richness and add crunch
- Rice vinegar: makes the pickles bright and zippy
- Sugar: in the quick pickle for balanced tang
- Salt: brings forward the flavors in both pickle and beef
- Red pepper flakes: totally optional for an extra kick in your pickles
Instructions
- Mix the Beef:
- Combine the ground beef with soy sauce, brown sugar, garlic, ginger and gochugaru in a medium bowl. Mix with a fork or hands just until everything is incorporated, taking care not to overwork which keeps the beef tender.
- Load into Slow Cooker:
- Spread the seasoned beef mixture in an even layer in your slow cooker insert. Drizzle sesame oil over all of it ensuring little pools for big flavor.
- Slow Cook:
- Cover with the lid and cook on low setting for four to five hours. If you are nearby give it a gentle stir halfway through. The beef is done when it is deeply browned and saucy.
- Pickle the Cucumber:
- While the beef cooks, thinly slice the cucumber and add it to a small bowl. Pour in rice vinegar, sugar, salt, and any optional red pepper flakes. Stir until everything is coated. Let sit for at least ten minutes but you will notice more flavor if you leave it closer to thirty.
- Warm the Tortillas:
- Near serving time, heat a dry skillet over medium. Warm each tortilla for about thirty seconds per side until soft and pliable. To do all at once wrap them in foil and pop into a three hundred fifty degree oven for about five to seven minutes.
- Finish the Beef:
- Right before assembling add sliced green onions into the beef. Give one last taste and season if needed.
- Assemble the Tacos:
- Layer beef onto warm tortillas and top with several slices of pickled cucumber. If you like, add extra toppings such as cilantro, radishes or a drizzle of sriracha mayo.
Choose crisp cucumbers and the freshest green onions you can find. Fresh garlic and ginger really shine here too.
Storage Tips
Let any leftover beef cool then store in an airtight container in the fridge up to three days. Pickled cucumbers last in the fridge a couple days holding onto their crunch. Briefly reheat beef on the stovetop or microwave with a splash of water to keep it moist.
Ingredient Substitutions
Ground turkey or chicken can stand in for beef just watch the texture. Tamari works for gluten free needs in place of soy sauce. If gochugaru is not available try a mix of sweet paprika and a little cayenne. Rice vinegar can be swapped with apple cider vinegar for the pickles.
Serving Suggestions
Serve with a slaw made of shredded cabbage and carrot for an extra fresh bite. Tacos go nicely with steamed rice or kimchi on the side. Drizzle with sriracha mayo or add some avocado if you want creamy richness.
