Pickled Red Onions should be in your fridge for all of your summer grilling adventures. They take minutes to prepare and are great to have on hand to top burgers, or use them chopped up in potato salad or as a crunchy side dish for tacos or almost anything.
You will reach for these onions often. Spoon them onto tacos, burgers, grain bowls, salads, or grilled meats. They sharpen rich food and wake up simple dishes.
Heather’s Notes
- You prep this recipe in under 10 minutes.
- The onions soften while staying crisp.
- The brine balances sweet, salty, and acidic flavors with a hint of spice from the arbol chile pods.
- The color turns vivid pink fast and looks great on the plate.
- You use pantry staples you likely keep on hand.
Pickled Red Onions Ingredient List
Start out with the quick pickling mixture. Here are some options to choose from, pick one or many:
- Black Peppercorns
- Arbol Chile Pods
- Smashed Fresh Garlic
- Juniper Berries
- Chili Flakes
- Fresh Rosemary
- Fennel Seed
Like other aromatics like thyme, sage, jalapeño? Flavor them as you see fit, just keep the first 4 ingredients the same and you will have delicious pickled red onions no matter what you do.
Now that it’s loaded with flavors, add in one peeled and sliced red onion and let the spices, cider and onions get to know each other. The acid in the vinegar will mellow the heat of the onion and give them a sweet and spiced flavor that’s amazing on top of a burger or pulled pork sammie.
