Preparation
Onions are a necessary ingredient for many fabulous dishes and burger recipes are no exception. Nearly every burger build recipe includes onions of some type. That being said, slicing onions is no fun. If the onions are strong or you aren’t prepared, it can be a recipe for disaster.
Tips For Cutting An Onion Without Tears
- A cold onion is less likely to bring on the fountain. Chill your onion in the refrigerator before slicing to avoid this nasty chemical reaction.
- Slice your onion quickly. Work as fast as you can safely chop, and minimize your exposure to the onion’s surface as much as possible.
- Blow a fan past your face as you chop the onion to clear away the fumes that are released as you cut the onion skin.
- Wear a mask. You’ll need a fancy one.
- Get someone else to cut your onions. 😀
Prepping Raw Onions
👉Rings: Classic and visually appealing, rings provide a satisfying crunch. To keep them from falling out, cut them thin and stack them.
👉Diced: Ideal for even flavor distribution. Dice them uniformly for a consistent bite and a neat presentation.
👉Long Slices: The best of both worlds, they offer a full-onion flavor without overpowering. Slice them thinly lengthwise to ensure they stay put within the bun.
Cooking Onions For Burgers
Cooked onions can transform a burger from good to gourmet. Here’s how to cook them in ways that can elevate your burger:
👉Grilled Rings: For a smoky touch, grill the onion rings until they have charred edges. This adds a rustic, savory flavor to your burger. Grilled sweet onions are one of our favorite burger toppings and a versatile BBQ side. Cut the onions into thick slices for grilling – once cooked, they are easy to separate into rings.
👉Fried Rings: A fan favorite, these are battered and deep-fried to golden perfection. They are an indulgent treat worth enjoying once in a while, despite the high-calorie count.
👉Caramelized: Slowly cook the onions until golden for a sweet, rich flavor. Perfect for adding depth to a classic burger.
👉Sautéed: Quickly fry the onions to retain some bite. They will have a softer texture than raw onions, and enhanced sweetness through the caramelization process.

Jason’s been firing up the grill for over 30 years after graduating from the US Coast Guard Academy. His love of finely-grilled steak and chicken led him to buy his first Weber grill to put on his apartment patio in 1992. Each military move led to a new grill (a mixture of gas and charcoal) until he fell in love with the Big Green Egg in 2008. Since then, he has added another 4 grills to the collection. Yes, he has a problem. Jason loves smoking in the ceramic BGE with exotic woods including olive wood from Egypt and hard to find varieties such as sassafras and orange wood. Jason takes the term “foodie” to a whole new level, jumping at the chance to take food tours and cooking classes during foreign travels. These have provided inspiration to incorporate new ideas into recipes when he gets back home. He has been featured in Fox News, Parade, Yahoo News, Kansas City Living and more. After retiring from the military and moving to southwest Florida, he has focused grilling and smoking locally sourced meats and fish (read: he likes to catch his own fish!)
