Step 1: Cook the Ground Beef

Heat olive oil in a skillet over medium-high heat.

Add the ground beef and cook until browned, breaking it apart with a spatula (about 6–8 minutes).

Drain excess grease.

Stir in taco seasoning and ¼ cup water. Let simmer for 3–4 minutes until thickened and fully coated. Set aside.

Step 2: Season and Cook the Shrimp

Pat shrimp dry with paper towels.

Toss shrimp in olive oil, paprika, chili powder, garlic powder, onion powder, cayenne, salt, and pepper.

Heat a skillet over medium-high heat and sear the shrimp for about 1–2 minutes per side, until pink and slightly charred around the edges.

Remove from heat and squeeze over a bit of lime juice if desired.

Step 3: Assemble the Nachos

On a large oven-safe platter or baking sheet, spread out a generous layer of Doritos chips (choose a bold flavor like Nacho Cheese or Spicy Sweet Chili for color and taste).

Spoon the seasoned beef evenly over the chips.

Add a layer of shredded cheese, making sure it covers most of the chips and beef.

If using nacho cheese sauce, drizzle some over the top for extra creaminess.

Bake or broil briefly (3–5 minutes at 375°F / 190°C) — just until the cheese is melted and bubbly.

Step 4: Add the Shrimp and Toppings

Once the nachos come out of the oven, top immediately with the cooked shrimp.

Sprinkle over diced tomatoes, red onions, jalapeño slices, and chopped cilantro.

Add a drizzle of sour cream or Mexican crema for a finishing touch.
