Instructions

Step 1: Separate 2 large yellow onions into rings and toss them in 1/2 cup all-purpose flour seasoned with 1/2 tsp black pepper and 1/2 tsp salt to coat. Set aside.
Step 2: In a large bowl, whisk 1 cup all-purpose flour, 1/2 cup cornstarch, 1 tsp baking powder, 1 tsp salt, 1 large egg, and 1 cup cold beer until smooth and thick. Fold in 1 cup shredded Wisconsin cheddar cheese.
Step 3: Heat 4 cups vegetable oil in a deep pot to 375°F. Dip each floured onion ring into the beer batter, letting excess drip off, then carefully place in hot oil. Fry in batches for 3-4 minutes until golden and cheese is melted, turning once.
Step 4: Remove onion rings with a slotted spoon and drain on paper towels.
Step 5: For the spicy aioli, mix 1/2 cup mayonnaise, 1 tbsp sriracha sauce, 1 tsp fresh lemon juice, and 1/4 tsp garlic powder in a small bowl until smooth.
Step 6: Serve hot beer-battered cheesy onion rings with spicy aioli on the side for dipping.
