Our air fryer has become a weekend MVP in our kitchen, and for good reason! Just a few weeks ago, we enjoyed a batch of Air Fryer Jalapeno Poppers, and shortly after, these incredible Air Fryer Mini Pepper Nachos made their debut. They feature sweet and crunchy mini bell peppers as the base, piled high with classic nacho toppings. This recipe offers all the joy of traditional nachos but without the heavy carbs, making it an ideal snack for game day, a light lunch, or a satisfying anytime treat!

Honestly, I believe these mini pepper nachos are even better than their classic counterparts. Why? Because they’re essentially 100% nacho toppings, and as every nacho enthusiast knows, the toppings are truly the best part! We love ours topped with thinly sliced pickled jalapeno peppers, briny black olives, juicy chopped tomatoes, crisp green onions, and fresh cilantro. But the beauty of nachos lies in their versatility—feel free to get creative with your favorite toppings! For those who enjoy a heartier option, shredded chicken or perfectly seasoned taco meat would be fantastic additions.

Ingredients for Air Fryer Mini Pepper Nachos
Gathering your ingredients for these delicious nachos is simple. Here’s what you’ll need to create this fantastic snack:

- Mini Peppers: These colorful, sweet little peppers are the star of the show! You’ll typically find them in small bags at your local supermarket, often labeled “sweet mini bell peppers” or “rainbow peppers.” You’ll need approximately 1 pound, which usually equates to one standard package. Look for firm, vibrant peppers without any soft spots. They make the perfect low-carb “chip” and offer a lovely, subtle sweetness that complements the savory toppings.
- Shredded Cheese: A good melt is key for nachos! While you can certainly shred cheese from a block for the freshest flavor and best melt, I often opt for a pre-shredded Mexican cheese blend for convenience. Many find that for nachos, pre-shredded cheese, which often contains anti-caking agents, works surprisingly well to create that classic gooey, slightly bubbly texture. Feel free to use your preferred type, such as cheddar, Monterey Jack, Colby, or even a spicy pepper jack for an extra kick!
- Sliced Jalapeno Peppers: These add a fantastic layer of flavor and a touch of heat. We used one generously sized jalapeno, but adjust the quantity to your preference. If you prefer a milder heat, be sure to remove the seeds and the white membrane inside the pepper, as this is where most of the capsaicin (the heat-causing compound) resides. For those who love things extra spicy, leave some seeds in! Pickled jalapenos also work wonderfully for a tangy bite.
- PLUS popular nacho toppings like:
- Chopped Green Onion: Adds a fresh, mild onion flavor and a beautiful pop of color. Make sure to use mostly the green parts for a vibrant garnish.
- Black Olives: Sliced black olives contribute a salty, briny depth that is a classic nacho ingredient.
- Chopped Tomatoes: Diced fresh tomatoes add a burst of juicy sweetness and acidity, balancing the richness of the cheese.
- Fresh Cilantro: A sprinkle of fresh, chopped cilantro brightens the dish with its distinctive, aromatic flavor.
How to Make Air Fryer Mini Pepper Nachos
Making these healthy nachos is incredibly straightforward, perfect for a quick snack or appetizer. Follow these simple steps for perfectly crisp and cheesy results:

Step 1: Preheat Your Air Fryer. Begin by preheating your air fryer to 390°F (199°C). Most air fryers take about 3 minutes to reach the desired temperature, but always refer to your specific model’s instructions for optimal preheating.
Step 2: Prepare the Peppers. While your air fryer preheats, wash your mini peppers thoroughly. Carefully cut each pepper in half lengthwise and remove any seeds and white membranes. Arrange the halved and seeded peppers in a single layer in the crisping tray or basket of your air fryer. Avoid overcrowding, as this can lead to uneven cooking and less crispy results. If you have a smaller air fryer, you may need to cook in batches.
Step 3: Add the Cheese. Generously sprinkle your choice of shredded cheese over the pepper halves. Ensure an even coating so every bite is wonderfully cheesy.
Step 4: Top with Initial Toppings. Distribute the black olives and sliced jalapeno peppers over the cheese. These ingredients cook well with the cheese and peppers, allowing their flavors to meld beautifully.
Step 5: Air Fry to Perfection. Cook the nachos in the preheated air fryer for 10-12 minutes. Keep an eye on them, as cooking times can vary by air fryer model. You’re looking for the cheese to be perfectly melted, bubbly, and beginning to brown around the edges, and the peppers to be slightly softened but still retain a pleasant crispness.

Step 6: Final Toppings & Serve. Carefully remove the crispy, cheesy nachos from the air fryer. Immediately sprinkle with your fresh toppings: chopped green onions, diced tomatoes, and fresh cilantro. Serve them hot and fresh!
Serving Suggestions: These nachos are fantastic on their own, brimming with flavor. However, for an extra treat, offer optional bowls of creamy sour cream, vibrant salsa, or even a dollop of fresh guacamole for dipping. While I’m usually a big fan of sour cream with conventional nachos, these mini pepper nachos are so flavorful, you might find you don’t need any dip at all!
Note for Smaller Air Fryers: If you have a compact basket-style air fryer, you might need to work in batches to ensure even cooking. For my smaller Ninja air fryer, I typically need 1.5 to 2 batches. Oven-style air fryers usually have more space and can accommodate a full batch. If cooking in batches, transfer the first portion to a plate and keep it warm while you finish the rest.

Variations and Substitutions to Customize Your Nachos
One of the best things about nachos is how easily they can be adapted to suit different tastes and dietary needs. Here are some ideas to make these Air Fryer Mini Pepper Nachos uniquely yours:
- Keto and Low Carb: These nachos are naturally keto and low carb! To add more protein and make them a more substantial meal, consider sprinkling on half a pound of browned and seasoned taco meat (beef, turkey, or even plant-based crumbles) before cooking. You can also add avocado slices or guacamole after cooking for healthy fats.
- Vegetarian: This recipe is vegetarian as written, making it a fantastic meat-free option. To amp up the veggie quotient, add extra diced bell peppers (any color), corn (if not strictly keto), or finely chopped red onion after cooking.
- Weight Watchers: To accurately track points, it’s best to input this recipe into your Weight Watchers app, as points can vary. Based on typical estimations, most non-starchy vegetables like mini peppers are 0 points, making them an excellent base. The points will primarily come from the cheese. You can lighten it further by using reduced-fat cheese or portioning carefully.
- Dairy Free: Easily make this recipe dairy-free by substituting the shredded cheese with your favorite dairy-free shredded cheese alternative. Many brands now offer excellent melting options made from plant-based ingredients.
- With Meat: For a heartier, protein-packed version, prepare about half a pound of cooked ground beef or turkey, seasoned with your favorite taco seasoning. Before adding the cheese, spread the seasoned meat over the halved peppers in the air fryer. Then proceed with layering the cheese, jalapenos, and olives before air frying. Add your fresh toppings like green onions, tomatoes, and cilantro once they come out of the air fryer.
- Spicy Kick: If you love heat, don’t hold back on the jalapenos! You could also add a pinch of cayenne pepper to the cheese, a dash of hot sauce before serving, or even some finely diced serrano peppers for an extra fiery punch.
- Mediterranean Twist: Try adding crumbled feta cheese, chopped Kalamata olives, and a sprinkle of dried oregano. Finish with fresh parsley and a squeeze of lemon juice.
- Loaded Veggie Boost: Incorporate finely diced red onions, a few corn kernels (if desired), and maybe even some thinly sliced mushrooms or spinach for a nutrient-dense addition.
Oven Instructions: No Air Fryer? No Problem!
Don’t have an air fryer yet? You can still enjoy these delicious Mini Pepper Nachos! While the air fryer gives them a unique crispness, they’re just as tasty baked in a conventional oven. Simply preheat your oven to 425°F (220°C). Arrange your prepped mini peppers with toppings on a baking sheet and bake for 18-22 minutes, or until the cheese is melted and bubbly and the peppers are tender-crisp. Keep an eye on them to prevent burning the cheese.
If you’re considering investing in an air fryer, here are two models I highly recommend:
Tips for the Best Air Fryer Pepper Nachos
- Don’t Overcrowd: For optimal crispiness and even melting, arrange peppers in a single layer. If your air fryer is small, work in batches.
- Evenly Slice Peppers: Try to keep your pepper halves roughly the same size for uniform cooking.
- Quality Cheese: While pre-shredded cheese works, freshly grated cheese often melts smoother and has a richer flavor. Choose your favorite!
- Adjust Spice: Control the heat from jalapenos by removing or leaving in seeds and membranes.
- Add Toppings After Frying: Delicate fresh toppings like green onions, tomatoes, and cilantro are best added after cooking to maintain their freshness and texture.
Storage and Reheating
While these nachos are definitely best enjoyed fresh from the air fryer, you might find yourself with leftovers (though unlikely!).
- Storage: Store any leftover nachos in an airtight container in the refrigerator for up to 2-3 days. Note that the peppers may soften, and the cheese will solidify.
- Reheating: To reheat, arrange them in a single layer in your air fryer basket and cook at 350°F (175°C) for 3-5 minutes, or until warmed through and the cheese is re-melted and bubbly. Alternatively, reheat in a preheated oven at 375°F (190°C) for 5-7 minutes. Avoid the microwave, as it will make them soggy.
Frequently Asked Questions (FAQ)
Here are answers to some common questions about making Air Fryer Mini Pepper Nachos:
- Can I use regular bell peppers instead of mini peppers? Yes, you can! You’ll just need to cut them into smaller, chip-like pieces to ensure they cook evenly and are easy to eat. Keep an eye on cooking time as larger pieces might take slightly longer.
- What kind of cheese melts best? A good quality shredded cheddar, Monterey Jack, Colby Jack, or a Mexican blend works perfectly. Mozzarella can also be used for a super stretchy melt.
- Can I add other vegetables? Absolutely! Feel free to experiment with finely diced red onion, corn (if not strictly keto), or even a few finely chopped mushrooms. Just make sure they are small enough to cook quickly alongside the peppers.
- How do I prevent the nachos from getting soggy? The key is not to overcrowd your air fryer basket and to cook them until the cheese is truly bubbly and slightly browned. This allows for moisture to evaporate. Also, adding fresh, watery toppings like tomatoes and salsa *after* cooking helps.
- Are these good for meal prep? These nachos are best enjoyed fresh. However, you can prep the peppers (halve and seed them) and chop your toppings in advance to save time when you’re ready to cook.
