For Assembly
- 10 crisp corn taco shells
- 2 cups finely shredded iceberg lettuce (about 1/4 small head)
- 1 1/2 cups finely grated sharp cheddar
- 1 cup diced ripe tomato (seeded)
- 3/4 cup sour cream
- Mild taco sauce (from above) or favorite store-bought

Step-by-Step Instructions
Step 1: Prep toppings and heat the oven
Set an oven rack in the middle and heat to 350°F (175°C). Finely shred the iceberg lettuce, dice the tomatoes (remove watery seeds for best crunch), and finely grate the cheddar on the small holes of a box grater. Spoon the sour cream into a small zip-top bag or piping bag; snip a tiny corner for a clean “Supreme” stripe later. Set everything in the fridge to keep it crisp.
Step 2: Make the mild taco sauce
In a small saucepan, combine tomato sauce, water, vinegar, sugar, chili powder, paprika, cumin, garlic powder, onion powder, salt, and optional cayenne. Bring to a gentle simmer over medium heat, then reduce to low and cook for 8–10 minutes, stirring occasionally, until slightly thickened and glossy. Cool to warm; it will thicken a touch as it rests.
Step 3: Mix the taco beef seasoning
In a small bowl, stir together chili powder, cumin, paprika, onion powder, garlic powder, oregano, coriander, sugar, salt, black pepper, and cornstarch. If using MSG, keep it aside to add at the very end so its flavor stays bright.
Step 4: Brown the beef
Heat a large skillet over medium-high. Add the oil if needed, then the ground beef. Cook, breaking into fine crumbles with a spatula or potato masher, until no pink remains and lightly browned, 5–6 minutes. Drain excess fat, then return the beef to the skillet.
Step 5: Make it saucy and signature
Sprinkle the mixed seasoning over the beef. Add 3/4 cup water and stir. Bring to a simmer over medium heat and cook, stirring often, until the liquid reduces to a thick, spoonable sauce that clings to the meat, 5–7 minutes. If using MSG, stir it in now. Keep warm on low.
Step 6: Warm and crisp the shells
Arrange taco shells on a baking sheet and heat at 350°F (175°C) for 5 minutes, just until fragrant and extra crisp. This keeps them from shattering on the first bite and helps them stay crunchy once filled.
Step 7: Assemble the Crunchy Taco Supreme
Build each taco in this order for that classic bite: spoon in seasoned beef (2–3 tablespoons), drizzle with mild taco sauce (about 1–2 teaspoons), add a fluffy handful of shredded lettuce, sprinkle with finely grated cheddar, top with diced tomato, and finish with a neat stripe of sour cream across the top. Serve immediately while the shells are at peak crunch.
Pro Tips
- Finely grate cheddar on the small holes for better melt and lighter texture.
- Keep lettuce very dry and cold so it stays crisp against the warm beef.
- Use a potato masher while browning to get those tiny, uniform beef crumbles.
- Do not skip the brief shell warm-up; it dramatically improves texture.
- For the most “fast-food authentic” flavor, add the optional MSG to the beef.
Variations
- Spicy: Swap mild taco sauce for medium or hot and add a pinch of cayenne to the beef.
- Lean twist: Use 93% lean ground turkey; add 1 tablespoon oil and an extra 2 tablespoons water when simmering.
- Plant-based: Use meatless crumbles; simmer gently with the seasoning and water for 3–4 minutes.
Storage & Make-Ahead
Beef and taco sauce can be made 3 days ahead. Cool, refrigerate separately, and reheat gently with a splash of water until saucy. Store shells in their box at room temperature; warm just before serving. Chop lettuce and dice tomatoes up to 6 hours ahead; keep chilled and well-dried. Assemble tacos only when ready to eat—the shells soften quickly once filled.
