Everything You Can Do with One Onion: Simple, Delicious Ways to Turn a Single Ingredient into Real Meals

Why the Onion Is One of the Most Versatile Foods You Own

Onions are the foundation of countless cuisines around the world - and for good reason.

One onion can:

• Add depth and sweetness to simple foods

• Create flavor even when ingredients are limited

• Stretch pantry staples into full meals

• Feel comforting, savory, and filling

They’re affordable, shelf-stable, and endlessly adaptable, making them a true kitchen essential.

The Magic That Happens When You Cook an Onion

Raw onions are sharp and pungent, but cooking transforms them completely.

As onions cook:

• Natural sugars caramelize

• Sharpness softens

• Savory depth develops

• Texture becomes rich and comforting

This transformation is why even one onion can anchor an entire meal.

First Things First: How to Prep One Onion for Multiple Uses

If you want to get the most out of a single onion, how you cut it matters.

• Diced: Best for soups, sauces, eggs, and rice dishes

• Sliced: Ideal for caramelizing, sandwiches, and topping toast

• Wedges: Great for roasting or pan-frying

You can even divide one onion and use it in different ways throughout the day.
