Cheesy Onion Crisp Ingredients
For the Crisps
• Onions – Use yellow or sweet onions for the best flavor and natural sweetness in your Cheesy Onion Crisps.
• Cheddar Cheese – Opt for sharp cheddar to enhance the flavor, or use mild cheddar if you prefer a subtler taste.
• Parmesan Cheese – This adds a nutty flavor and promotes browning; Grana Padano can be a great alternative.
• Butter – Provides richness; swap it for olive oil if you’re looking for a dairy-free option.
• Flour – Acts as a binder and ensures a crispy texture; consider gluten-free flour as a substitute.
• Salt and Pepper – Essential for seasoning; remember to adjust to your taste preference!
Step‑by‑Step Instructions for Cheesy Onion Crisp
Step 1: Prepare the Onions
Begin by slicing your onions thinly. In a large skillet, melt 2 tablespoons of butter over medium heat, then add the onions and sauté for about 10-15 minutes. Stir occasionally until the onions become translucent and are lightly caramelized, achieving a lovely golden color that enhances their natural sweetness. This aromatic base is essential for your Cheesy Onion Crisp.
Step 2: Mix the Batter
In a mixing bowl, combine the sautéed onions with 1 cup of shredded sharp cheddar cheese and ½ cup of grated Parmesan cheese. Pour in the melted butter from the skillet, followed by ½ cup of flour, and season with salt and pepper to taste. Stir the mixture until it forms a cohesive dough that holds together well, ensuring an even distribution of your cheesy goodness.
Step 3: Shape the Crisps
Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper for easy cleanup. Using a spoon, scoop out the mixture and place it onto the prepared baking sheet, flattening each scoop into rounds about ¼ inch thick. Ensure there’s enough space between each round for optimal baking and crisping, creating your delightful Cheesy Onion Crisps.
Step 4: Bake
Slide the baking sheet into your preheated oven and bake for 20-25 minutes. Keep an eye on the crisps as they transform into a beautiful golden brown color, signaling that they are perfectly done. The aroma wafting through your kitchen will be irresistible, drawing everyone closer to the source of the deliciousness.
Step 5: Cool and Serve
Once baked, remove the Cheesy Onion Crisps from the oven and let them cool on a wire rack for a few minutes. This cooling step helps maintain their crispy texture. Serve them warm at your festive gathering, and enjoy as guests savor each delightful bite.
