Ingredients and Their Roles

Main Ingredients

• Ground beef (1 lb): Provides protein and rich savory flavor. An 80/20 blend works best.
• Onion (1 medium, diced): Adds sweetness and depth when sautéed.
• Long-grain white rice (1 cup): Absorbs flavor while staying fluffy.
• Beef broth (2 cups): Adds moisture and savory richness.
• Tomato sauce (1 cup): Creates a smooth and balanced base.
• Salsa (½ cup): Adds authentic Mexican zest and tang.
• Corn (1 cup, drained): Adds sweetness, texture, and color.
• Shredded cheese (1 cup): Cheddar or Mexican blend for a creamy, gooey finish.
• Salt and black pepper: Enhances all flavors.

Optional Toppings

• Fresh cilantro
• Green onions
• Diced avocado
• Sour cream or Greek yogurt

Step-by-Step Instructions

Step 1: Cook the Ground Beef and Onion

Heat a large skillet over medium-high heat. Add the ground beef and diced onion. Cook for 6–8 minutes, breaking up the meat as it browns. Season lightly with salt and black pepper. Drain excess fat once cooked.

Step 2: Add the Seasoning

Stir in 2 teaspoons of taco seasoning (or cumin, paprika, chili powder, and garlic powder). Cook for 1–2 minutes to release the spices’ aroma.

Step 3: Add Rice and Liquids

Add the rice and stir to coat with the beef mixture. Pour in the beef broth, tomato sauce, and salsa. Stir well and bring to a gentle boil.

Reduce heat to low, cover, and simmer for 18–20 minutes, stirring occasionally until the rice is tender.

Step 4: Add Corn and Cheese

Fold in the drained corn. Sprinkle shredded cheese evenly over the top, cover, and let melt for 2–3 minutes until gooey.

Step 5: Garnish and Serve

Taste and adjust seasoning if needed. Garnish with cilantro, green onions, or avocado. Let rest for 5 minutes before serving.
