White Onions in the Kitchen: Delicious and Versatile
Here are a few creative recipe ideas that feature white onions as a main ingredient:
Grilled White Onion and Avocado Salad: Slice a large white onion into 1/2-inch thick rounds, brush with olive oil, and grill until tender and slightly charred. Serve the grilled onion slices on top of a bed of mixed greens, along with sliced avocado, cherry tomatoes, and a simple vinaigrette dressing.
Creamy White Onion Soup: Sweat a large diced white onion in butter until it is soft and translucent. Add a few cloves of minced garlic and cook for an additional minute. Stir in a quart of chicken broth, a white wine splash, and a thyme sprig. Bring the soup to a boil, then reduce the heat to a simmer and let it cook for 20-30 minutes.
Remove the thyme sprig and puree the soup with an immersion blender until smooth. Stir in a cup of heavy cream and season with salt and pepper to taste. Serve the soup hot, garnished with croutons and grated Parmesan cheese.
Caramelized White Onion and Blue Cheese Tart: Roll out a store-bought pie crust and press it into a tart pan. Slice a large white onion into thin wedges and caramelize it in a skillet with a bit of butter and sugar until it is soft and golden brown. Spread the caramelized onion over the pie crust, then top with crumbled blue cheese and a sprinkle of thyme. Bake the tart in a 350°F oven for 20-25 minutes, or until the crust is golden and the cheese is melted.
Spicy White Onion and Black Bean Quesadillas: Thinly slice a white onion and sauté it in a skillet with some diced jalapeño peppers and a can of drained and rinsed black beans. Spread the onion and bean mixture over half of a flour tortilla, then top with grated cheese and a few sprigs of fresh cilantro.

Tips for selecting, storing, and preparing white onions in the kitchen
- When selecting white onions at the grocery store or farmer’s market, look for firm, heavy bulbs with smooth, papery skin. Avoid onions that are soft or have visible blemishes, as these may be past their prime.
- To store white onions, keep them in a cool, dry place away from direct sunlight. They can be stored whole or cut, but be sure to wrap them tightly in plastic wrap or store them in an airtight container to prevent them from drying out.
- When preparing white onions for cooking, slice them evenly for consistent results. If you find the flavor of raw white onions too strong, you can also soak them in water for a few minutes before using them in a recipe to help mellow out the flavor.
- To caramelize white onions, slice them thinly and simmer them in a skillet with a bit of butter and sugar until they are soft and golden brown. This can take anywhere from 20-30 minutes, depending on the size of the onions and the heat of your stove.
- To roast white onions, slice them into wedges and toss them with olive oil, salt, and any desired seasonings. Roast the onions in a 400°F oven for 20-30 minutes or until they are tender and caramelized.
- To add a burst of flavor to soups, stews, and other dishes, try using a white onion studded with a few cloves of garlic. Cut off the top and bottom of the onion, slice it in half vertically, and push a few cloves of garlic into the cut sides of the onion.
Roast the onion in a 400°F oven for 45 minutes or until it is soft and caramelized. When it’s cool enough to handle, squeeze the soft onion and garlic out of the skin and into the pot. The onion and garlic will melt into the dish, adding a depth of flavor that can’t be beat.
