These buttermilk onion rings achieve exceptional crispiness through a two-step breading technique: a seasoned flour dredge followed by a panko coating. The buttermilk soak infuses flavor while tenderizing the onions for a perfect contrast between crunchy exterior and tender interior.

Instructions

1
Trim the ends of the onion, peel it, and slice into thick rings. Separate the rings.
2
Place the onion rings in a large bowl and cover with buttermilk.
3
To the buttermilk, add hot sauce, garlic powder, smoked paprika, and chipotle chili powder. Gently mix to combine, being careful not to break the rings. Let the onions soak.
4
In a separate large bowl, combine the all-purpose flour, corn starch, and the same spices: garlic powder, smoked paprika, and chipotle chili powder. Whisk to combine.
5
Take an onion ring from the buttermilk marinade, let the excess drip off, and dredge it thoroughly in the seasoned flour mixture.
6
Dip the flour-coated ring back into the wet buttermilk mixture.
7
Immediately transfer the ring to a tray of panko breadcrumbs and press gently to coat completely. Repeat for all rings.
8
Heat vegetable oil in a deep fryer or large pot to 350°F (175°C).
9
Carefully fry the onion rings in batches for about 4 minutes, or until they are deep golden brown and crispy.
10
Remove the onion rings from the oil and place them on a wire rack to drain excess oil.
11
Immediately season with a sprinkle of flaky salt. Serve hot.

Tips & Notes

Pro tips

Use a mandoline or sharp knife to slice onions uniformly—thicker rings (about ¼ inch) hold their shape better and stay tender inside while the coating crisps.
Separate onion slices into individual rings and pat dry before buttermilk soaking to remove excess surface moisture, which improves breading adhesion.
Work in small batches and let oil temperature recover between batches—overcrowding drops oil temp and produces greasy rings instead of crispy ones.
Serve immediately after frying while the panko coating is still crackling; even 5 minutes at room temperature allows steam to soften the exterior.

Substitutions

Buttermilk → equal parts Greek yogurt + water or milk + 1 tbsp lemon juice (for tang and cling)
All-purpose flour → 1 cup all-purpose + ½ cup rice flour (for extra crispiness)
Panko breadcrumbs → Japanese panko (finer crunch) or crushed saltine crackers (pronounced crunch)
Hot sauce → omit or replace with sriracha or Frank's RedHot (adjust buttermilk liquid ratio if very thin)

Storage & make-ahead

Store cooled rings in an airtight container at room temperature up to 4 hours, or refrigerate up to 2 days. Reheat on a wire rack in a 375°F oven for 5-7 minutes to restore crispness.

Common Questions

Why do you use a buttermilk soak for onion rings?

Buttermilk tenderizes the onions and creates a flavorful base that adheres well to the flour coating. The acidity also helps the breading stick better during frying for maximum crispiness.

What's the benefit of the double dredge method?

Dredging first in seasoned flour, then panko breadcrumbs creates two distinct crispy layers. The flour acts as an adhesive base, and panko adds dramatic crunch and surface area.

How do you know when onion rings are done frying?

They should be deep golden brown with no pale spots, typically 2-3 minutes per batch. The coating should be rigid and shatter slightly when bitten.

Can you make onion rings ahead of time?

Bread them up to 2 hours ahead and refrigerate unbaked, or freeze breaded rings for up to 1 month. Fry from frozen, adding 30-60 seconds to cooking time.
