Why Make Tostadas Without Frying?

Traditional tostadas are usually deep-fried in oil, which significantly increases the fat and calorie content.

This version keeps things lighter by:

• Not frying the tortillas
• Cooking the ground beef in water to remove excess fat
• Using 90/10 or 93/7 lean ground beef
• Replacing sour cream with plain yogurt

How to Make Ground Beef Tostadas (Step-by-Step)

1. Cook the Ground Beef Without Excess Fat

Place the ground beef in a skillet with enough water to cover it and a pinch of salt.

Cooking the beef in water allows the fat to separate naturally. Once fully cooked:

• Drain using a colander

Blend:

• 3 raw tomatillos

Then add ½ cup plain yogurt and blend again.

You’ll get a creamy avocado sauce — like a lighter guacamole crema — perfect for topping tostadas.

• Minced garlic
