Ingredients You’ll Need
- 1½ cups shredded cheddar cheese (or a mix of cheddar and mozzarella)
- 1 cup caramelized onions (see below)
- 2 tbsp grated parmesan cheese
- ¼ cup breadcrumbs (optional for extra crunch – use gluten-free if needed)
- ½ tsp garlic powder
- ¼ tsp black pepper
- Pinch of salt (if cheese isn’t salty enough)
- Fresh thyme or chopped chives (optional, for garnish)
For Caramelized Onions:
- 2 large onions, thinly sliced
- 1 tbsp butter or olive oil
- Pinch of salt
- ½ tsp sugar (optional, to speed up caramelizing)
Tools You’ll Need
- Skillet
- Baking sheet
- Parchment paper or silicone mat
- Spatula
- Grater (for cheese, if using block)
Step-by-Step Instructions
Step 1: Caramelize the Onions
Heat butter or olive oil in a skillet over medium-low heat.
Add sliced onions and a pinch of salt.
Cook slowly, stirring often, for 20–30 minutes until deeply golden and sweet.
Add sugar if desired to speed up caramelization. Set aside to cool.
Step 2: Preheat the Oven
Preheat oven to 375°F (190°C).
Line a baking sheet with parchment paper or a silicone mat.
Step 3: Mix the Crisp Base
In a bowl, combine shredded cheese, parmesan, garlic powder, pepper, and breadcrumbs (if using).
Fold in cooled caramelized onions until evenly distributed.
Step 4: Shape the Crisps
Scoop heaping tablespoons of the mixture and place on the baking sheet, spacing at least 2 inches apart.
Flatten slightly into discs (they will spread while baking).
Step 5: Bake to Perfection
Bake for 8–10 minutes, or until edges are golden brown and crisp, and cheese is bubbly.
Let cool on the baking sheet for 5 minutes to firm up, then carefully lift with a spatula.
Step 6: Serve & Enjoy
Serve warm for maximum melty goodness, or cool completely for crispier texture.
Sprinkle with herbs for a finishing touch if desired.
Tips for Success
Don’t Skip the Parchment – Prevents sticking and helps the crisps lift cleanly.
Shred Cheese Fresh – Pre-shredded cheese has additives that affect melting.
Let Them Cool – They’ll firm up and crisp more as they sit.
Smaller Mounds = Crispier Texture – Make larger ones if you prefer a chewy center.
Experiment – Add spices, swap cheeses, or include a pinch of red pepper for heat.
Serving Suggestions
As a Snack – Enjoy straight off the tray for cheesy bliss.
On Soup – Float on top of tomato or French onion soup.
With Dip – Pair with ranch, sour cream, or a creamy garlic dip.
As a Salad Topper – Adds crunch and cheesy flavor to greens.
In Sandwiches – Use as a cheesy layer inside burgers or grilled cheese.
How to Store & Reheat
Storing:
Room Temp: Store in an airtight container for 2–3 days.
Refrigerate: Store up to 1 week, but crisps may soften slightly.
Freezing:
Not recommended—texture may suffer upon thawing.
Reheating:
Oven or Toaster Oven: Reheat at 350°F (175°C) for 5 minutes to re-crisp.
Avoid Microwave – Will soften instead of crisping.
Frequently Asked Questions
- Can I use a different cheese?
Yes! Try gouda, Monterey Jack, gruyère, or even a spicy pepper jack. - What if I don’t want to caramelize onions?
You can sauté them quickly or use pre-cooked onions for convenience, but caramelizing adds the best flavor. - Can I make these ahead of time?
Yes, but they’re crispiest fresh. Store in a dry container and reheat if needed. - Are they gluten-free?
Yes, if you skip the breadcrumbs or use a gluten-free alternative. - Can I make them in a mini muffin pan for thicker bites?
