Heat a dutch oven with peanut oil on the stovetop over medium heat, until oil reaches 425F.
In a bowl combine flour and spices, whisk thoroughly. Add the beer to the dry ingredients to make a batter.
Slice the onions into 1/4 inch rings. Dredge a few at a time in the batter and then into a bowl with the reserved flour.*
Fry the onion rings for 3-5 minutes. Remove and place on a plate with a paper towel to drain excess grease. Check the oil temperature before starting each new batch. When completed, enjoy with your favorite sauce.
*You can also put the reserved flour in a gallon-sized Ziploc bag and shake the onion rings. Just be aware that you might not have super even coverage of batter on your onion doing it this way. But the process will go quicker and they will still taste amazing.
