Keto Pepperoni Cheese Crisps (2-Ingredient Snack!)

Meet the crunchy, salty, cheesy snack you can make in one sheet pan: Keto Pepperoni Cheese Crisps. They’re wildly simple, come out shatter-crisp, and hit that pizza-ish craving without the carbs.

All you need is sliced pepperoni and shredded cheese. A hot oven does the rest. Make a batch for movie night, lunchboxes, or to top your favorite salads.

Why These Crisps Work So Well

The fat in pepperoni and cheese crisps up quickly, so you get seriously crunchy edges with a chewy, cheesy center that sets firm as it cools. No flours, binders, or special tools needed.

They’re done in about 10 minutes, and you can scale the batch for meal prep. If you like simple low-carb ideas like this, you might also enjoy these simple keto meal ideas for this week or my quick 10-minute keto lunch bowl when you need something fast.

What You Need (Just 2 Ingredients)

Good pepperoni and a melt-friendly cheese are all it takes. Use standard, not thick-cut, slices so they crisp evenly.

• 24 pepperoni slices, standard thickness
• 1 1/2 cups shredded mozzarella cheese, loosely packed

How to Make Pepperoni Cheese Crisps

Line the pan, arrange, top with cheese, and bake until bubbly and golden.

1. Preheat the oven to 375°F (190°C). Line a large rimmed baking sheet with parchment paper or a silicone baking mat.
2. Blot the pepperoni slices with a paper towel to remove surface oil. This helps them crisp instead of puddling grease.
3. Arrange the pepperoni on the lined sheet in a tight grid with at least 1 inch of space between slices.
4. Top each pepperoni slice with about 1 tablespoon of shredded cheese, keeping the cheese mounded in the center so it melts outward evenly.
5. Bake for 8 to 10 minutes, until the cheese is fully melted, bubbling, and the edges are spotty golden. Watch closely in the last 2 minutes.
6. Remove the pan from the oven and let the crisps cool on the sheet for 5 minutes to set and firm up.
7. Blot any excess oil gently with a clean paper towel. Transfer crisps to a wire rack to finish cooling completely for maximum crunch.
8. Serve warm or at room temperature. For dipping, offer marinara or ranch if desired.

Storage, Make-Ahead, and Reheating

Let crisps cool fully, then blot any excess oil. Store in an airtight container at room temperature for up to 24 hours, or refrigerate for 4 to 5 days. For best crunch, slip a paper towel in the container to absorb moisture.

Re-crisp in a 300°F (150°C) oven or toaster oven for 3 to 5 minutes until sizzling at the edges again. Avoid microwaving to reheat; it softens them. You can also bake a double batch and keep them chilled for snacks and salad toppers through the week.

Common Mistakes to Avoid

• Skipping parchment or a silicone mat: Cheese can weld to the pan; use a liner for easy release.
• Using thick-cut pepperoni: It stays chewy and can burn around the edges before the cheese crisps.
• Too much cheese per slice: More than about 1 tablespoon can pool and spread into one giant crisp.
• Pulling them too early: Bake until the cheese is bubbly and spotty golden; pale cheese will cool soft, not crisp.
• Not cooling on the pan: They firm up as they cool. Give them 5 minutes before moving.

Easy Variations and Substitutions

• Cheese swap: Try cheddar, Colby Jack, or Parmesan. Harder cheeses make a lacier, ultra-crisp texture.
• Spicy kick: Sprinkle a pinch of crushed red pepper or a dusting of chili powder over the cheese before baking.
• Pizza vibe: Add a light shake of Italian seasoning or garlic powder. Keep seasonings minimal so they don’t burn.
• Air fryer: 360°F (182°C) for 5 to 7 minutes on a lined basket, checking early. They brown fast.
• Dipping sauce: Serve with warmed low-sugar marinara. For a crispy side, try these keto onion rings too.

What to Serve With These Crisps

They’re great solo, but I love them with a small bowl of marinara, ranch, or pesto for dipping. Crumble a few over salads for crunch instead of croutons. Pair with a quick dinner like keto sheet pan sausage and veggies or serve alongside a cozy bowl of keto chicken and dumplings for contrast.

Keto Pepperoni Cheese Crisps FAQ

Can I use turkey pepperoni?

Yes. Turkey pepperoni works, but it has less fat, so the crisps may be slightly less rich and can brown faster. Keep a close eye near the end of baking and pull when the cheese is spotty golden.

Which cheese makes the crispiest result?

Parmesan and cheddar get the crispiest and laciest. Mozzarella melts smoothly and stays a touch chewier. A 50/50 cheddar–mozzarella blend is a great middle ground.

How do I keep them from getting greasy?

Blot pepperoni slices before baking and again right after they come out of the oven. Cooling on the pan for a few minutes helps fat settle and crisp instead of pooling.

Can I make them in the microwave?

You can. Place pepperoni on a paper towel–lined plate, top with cheese, and microwave in short bursts until bubbling and slightly golden. They crisp as they cool, but the texture is less even than baking.

Do they stay crisp for meal prep?

They’re crispiest on day one. For prep, store with a paper towel and re-crisp in a 300°F (150°C) oven for a few minutes. They’ll return to a crunchy, snackable texture.
