💭 Why you’ll love this recipe
Ready in 30 minutes: This recipe only requires about 5 minutes of active prep time, and comes together in just 30 minutes total! Super versatile: I love adding these roasted red onions to tacos, sandwiches, or salads. They taste great on my fried avocado tacos and on my Korean street toast sandwich! Needs just four ingredients: Can this recipe get any better? Of course, there are a bunch of toppings and seasonings you can add but you really just need onions, neutral cooking oil, salt and pepper for the most crispy and flavorful onions! To take the flavors to a next level, consider adding onion flakes on top!
📋 Ingredients and notes
You’ll need a large red onion, about a tablespoon of neutral cooking oil (I use avocado oil) and then salt and pepper.
Notes and Variations
Other types of onions: I prefer red onions since they’re sweet and caramelize well. I’ve tried them with mild yellow onions before and they tasted okay, but I preferred the red onions. I recommend not using white or Vidalia onions since they are quite pungent! Types of cooking oil: I prefer avocado oil as a base oil for many recipes because it’s neutral flavored and has a high smoke point! You could use olive oil as well, but in that case, I’d suggest lowering your oven temperature to 375F and cooking a bit longer instead of roasting at 400F as written in the recipe. Notes provided in the recipe card!
📖 How to make easy roasted red onions
Slice the onion into thin rounds
Wash and cut off the root edges of the onion, and peel the skin. First, cut the onion into two halves. Then, slice each half into a series of circular onion slices.
Preheat oven to 400F and season the onion
Preheat your oven to 400F. Then, lay out the onions in a thin layer in an oven proof baking dish (or better yet, a nice enameled cast iron braiser or skillet!) Drizzle olive oil, and top with salt and pepper. Toss the onion rings and spread them out so they’re well seasoned.
Bake in the oven for 20 minutes
Place the baking dish in the oven and roast / bake for 10 minutes first. Then take the skillet out carefully using oven mitts, and then toss them a bit more (or flip them). You can skip this step and cook the full 20 minutes as well, but I prefer taking them out halfway since I find this browns the two sides evenly! Cook until the onion rings are nicely caramelized, crispy on the outside, but tender to bite. Your roasted red onions are ready!
🍴 Serving and storage suggestions
Roasted red onions are good in the fridge in an airtight container for at least a couple of days. You can either reheat them in a microwave or if you want to preserve the crispiness, throw them on a skillet to warm up (or add them on top of scrambled eggs!) Sometimes I add them to my crispy kimchi pancakes for a fun, Korean-inspired breakfast!
