Instructions

  1. Step 1: In a large skillet over medium heat, cook 1 lb ground beef until browned, breaking it into small crumbles. Drain excess fat, then stir in 2 tbsp fajita seasoning and cook for 2 more minutes until fragrant.
  2. Step 2: Warm 12 corn tortillas in a dry skillet for 30 seconds per side until pliable and slightly crisp. Set out a large platter with warm tortillas arranged around the perimeter.
  3. Step 3: Place 2 cups shredded lettuce, 1 cup diced tomatoes, 1 cup shredded cheddar cheese, 1/2 cup sour cream, and 2 diced avocados in separate bowls in the center of the platter. Let guests assemble their own tacos by layering desired ingredients onto a warm tortilla.

Frequently asked questions

How long does Build-Your-Own Fun Tacos take to make?

Total time is about 40 minutes (25 min prep + 15 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Build-Your-Own Fun Tacos?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep ground beef from drying out.

Can I substitute ingredients in Build-Your-Own Fun Tacos?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Build-Your-Own Fun Tacos for a different number of people?

The recipe is written for 6 servings. Multiply each ingredient by (your serving target / 6). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

What goes well with Build-Your-Own Fun Tacos?

Mexican quick meals like this pair well with a simple grain (rice, couscous, or crusty bread), a quick salad with acid (lemon vinaigrette, pickled onions), and a pan sauce or yogurt-based dip. Tap "Plan a meal with the AI" to get specific side suggestions.
