Toss onion rings and 1/4 cup Bisquick. Stir remaining 2 cups Bisquick, beer, salt and eggs until smooth. (If batter seems too thick, add more beer, 1 tablespoon at a time, until it reaches the desired consistency).
Light, fluffy, and super crunchy, this onion ring batter gets its perfect texture from Bisquick! The very BEST Beer Battered Onion Rings that are so easy to make! If you want a compact recipe try this.
