With their crispy golden outside and soft, sweet interior, these homemade onion rings are impossible to resist. Serve with your favorite dipping sauce like the Awesome Blossom Sauce in the notes below.
1 large sweet or yellow onion, thickly sliced into 1/2-inch thick rings
1 cup milk
1 Tbsp white vinegar
1/2 cup sour cream
1 cup all-purpose flour
1/2 Tbsp salt
1/4 tsp black pepper
1 tsp garlic powder
Oil for frying, I used canola oil – use something with a high smoke point
How to Make the best onion rings:
Heat a dutch oven over medium heat with 1″ of oil (or enough to cover the onion rings). You can use a deep fryer if you have one.
In a medium bowl, whisk together 1 cup milk with 1 Tbsp vinegar and let sit 5 minutes. Whisk in 1/2 cup sour cream.
In a separate bowl, whisk together: 1 cup flour, 1/2 Tbsp salt, 1/4 tsp black pepper, and 1 tsp garlic powder.
Separate the onion rings and dip each ring in the milk mixture, then dredge with flour. (I used a fork to transfer from the wet bowl to the dry bowl so my hands didn’t get as gunky). Repeat by dipping in milk mixture a second time and dredging again in flour. Place the finished onion rings on a plate until ready to fry.
Once the oil is at 375˚F on a thermometer, or hot enough for the onion rings to sizzle, place 3-4 double battered onion rings in a single layer in the hot oil and cook for about 3 minutes, flipping halfway and fry until exterior is crisp and light golden brown. Let onion rings cool on paper towels so soak up any excess oil.
