The air fryer has earned its spot as a versatile kitchen appliance, allowing home cooks to prepare healthier and quicker meals. While it seems like an air fryer can handle almost anything, there are certain limitations to this modern gadget. Understanding what cannot be cooked in an air fryer is crucial to avoid culinary mishaps, maintain the appliance’s performance, and ensure the best possible results for your meals.
In this post, we’ll explore in-depth the foods that don’t work well in an air fryer, provide tips for overcoming these challenges, and include internal links to help you discover what the air fryer truly excels at. By the end of this article, you’ll know exactly how to get the most out of your air fryer while avoiding common pitfalls.
Foods That Don’t Work Well in an Air Fryer
1. Wet-Battered Foods
Foods coated in wet batters, like beer-battered fish, tempura shrimp, or funnel cakes, are unsuitable for air fryers. The wet batter drips off during cooking, failing to set properly. This creates a mess in the basket and leaves you with a soggy dish rather than the desired crispiness.
Why It Doesn’t Work: Unlike deep frying, the air fryer does not submerge food in hot oil to cook the batter evenly. Instead, it uses hot air circulation, which doesn’t allow the batter to solidify and crisp up.
Alternative Solution:
Instead of a wet batter, opt for a dry coating. Use almond flour, coconut flour, crushed pork rinds, or Parmesan cheese to coat your food. For example, try these keto mozzarella sticks for a low-carb, crispy snack.
2. Leafy Greens
Leafy greens like spinach, kale, and arugula don’t work well in an air fryer unless prepared carefully. Their lightweight nature causes them to fly around inside the air fryer, resulting in uneven cooking or even burning.
Why It Doesn’t Work: The strong airflow inside the air fryer is too intense for delicate greens.
Alternative Solution:
To make kale chips or other crispy greens, lightly coat them with oil and seasonings, then place them in a single layer in the air fryer. Use a rack or skewer to hold the greens in place. For a complete veggie guide, check out keto vegetable recipes.
3. Whole Roasts or Large Cuts of Meat
While the air fryer is great for smaller portions of meat like chicken thighs or steak bites, it struggles with large cuts of meat such as whole turkeys, pork shoulders, or large roasts. These items won’t cook evenly due to the limited space and airflow in the basket.
Why It Doesn’t Work: Air fryers lack the capacity and even heat distribution needed for large cuts of meat.
Alternative Solution:
Divide the meat into smaller portions for more even cooking. For instance, cut a roast into smaller chunks or cook individual chicken parts. Learn more about preparing perfect air fryer chicken in our chicken recipe guide.
4. Foods with High Water Content
Foods like watermelon, cucumbers, and tomatoes are high in water content and don’t hold up well in the air fryer. They tend to become mushy, lose their structure, or fail to crisp up properly.
Why It Doesn’t Work: The intense heat and airflow evaporate water quickly, leaving the food limp or overcooked.
Alternative Solution:
Focus on sturdier vegetables such as zucchini, cauliflower, broccoli, or Brussels sprouts, which roast beautifully in an air fryer. You can find inspiration in our air fryer keto recipes.
5. Cheese by Itself
Cooking shredded cheese or blocks of cheese directly in an air fryer is a recipe for disaster. The cheese melts and drips through the basket, creating a sticky mess that’s difficult to clean.
Why It Doesn’t Work: The melting point of cheese means it liquefies before it can crisp, especially without a supporting structure.
Alternative Solution:
Try recipes where cheese is contained, such as cheese crisps or stuffed mushrooms. These are great low-carb options and are detailed in our keto snack ideas.
6. Saucy or Sticky Foods
Foods drenched in sauces or sticky marinades, like barbecue chicken or honey-glazed salmon, are problematic in an air fryer. The sauce drips to the bottom of the basket, potentially burning and causing a mess.
Why It Doesn’t Work: The high heat of the air fryer causes sugary sauces to caramelize and burn quickly.
Alternative Solution:
Cook the food in the air fryer first, then add the sauce or glaze during the final 2–3 minutes of cooking to achieve a perfect finish. Learn how to make perfectly cooked proteins in our air fryer protein guide.
7. Raw Grains or Pasta
Raw grains like rice, quinoa, or uncooked pasta need boiling water to cook properly, which the air fryer cannot provide. Attempting to cook these in an air fryer will result in undercooked, hard grains.
Why It Doesn’t Work: Air fryers are designed for dry heat cooking, not liquid-based methods.
Alternative Solution:
Cook grains and pasta using traditional methods, then use the air fryer for dishes like fried rice or baked pasta casseroles.
8. Delicate Fish
While air fryers are excellent for cooking firmer fish like salmon or cod, delicate fish like tilapia or flounder can fall apart due to the intense air circulation.
Why It Doesn’t Work: Delicate fish doesn’t have enough structural integrity to withstand the airflow and heat of the air fryer.
Alternative Solution:
Bread delicate fish to give it extra structure, or cook it using parchment paper to prevent sticking and breakage.
9. Soups, Stews, or Liquid-Based Dishes
Air fryers are not suitable for cooking soups, stews, or other liquid-based dishes. The liquid can evaporate or leak, causing a mess and potentially damaging the appliance.
Why It Doesn’t Work: Air fryers are not designed to handle liquids or large amounts of moisture.
Alternative Solution:
Prepare these dishes in a slow cooker or Instant Pot. Use the air fryer for crispy toppings, such as croutons or fried onions.
10. Overcrowded Foods
Overcrowding the air fryer basket is a common mistake. When too much food is packed into the basket, the hot air cannot circulate properly, leading to uneven cooking and a lack of crispiness.
Why It Doesn’t Work: Air circulation is key to air frying. Overcrowding blocks airflow and prevents food from crisping.
Alternative Solution:
Cook food in smaller batches and arrange it in a single layer. If you’re cooking large amounts, consider using an air fryer with dual baskets or an accessory rack to maximize space.

Final Thoughts: Maximizing Your Air Fryer Experience
The air fryer is an incredible kitchen tool that offers a healthier, faster, and more convenient way to cook a variety of foods. From crispy low-carb tortilla chips to perfectly roasted vegetables and juicy proteins, this appliance can transform your meals with minimal oil and maximum flavor. However, like any kitchen gadget, it has its limitations—and understanding what works best in an air fryer will help you get the most out of it.
What to Avoid in the Air Fryer
While the air fryer excels at crisping and roasting, certain foods don’t fare well due to their texture or moisture content:
- Wet Batters – Foods coated in traditional liquid batters (like tempura or beer-battered fish) don’t crisp properly and can create a sticky mess. Instead, opt for pre-breading techniques like using almond flour or crushed pork rinds for a keto-friendly alternative.
- Foods with High Water Content – Vegetables like raw leafy greens (e.g., spinach or kale) can become too light and may blow around inside the air fryer. Instead, try heavier vegetables like zucchini, bell peppers, or Brussels sprouts.
- Excessively Sauced Foods – Dishes with too much sauce, such as stewed meats or heavily marinated items, may not cook evenly and can create smoke inside the air fryer. Instead, air-fry meats first and add sauces afterward for better texture and flavor.
Making the Most of Your Air Fryer
To get the best results, focus on foods that cook well in an air fryer, such as:
- Crispy Low-Carb Snacks – From homemade tortilla chips to cheese crisps and veggie fries, the air fryer makes it easy to enjoy crunchy, guilt-free treats.
- Proteins & Meats – Chicken wings, salmon, steak, and pork chops cook beautifully in the air fryer, developing a golden crust with tender interiors.
- Roasted Vegetables – Get perfectly caramelized Brussels sprouts, zucchini, cauliflower, or asparagus with just a light coating of oil and seasonings.
- Quick & Easy Meal Prep – Air fryers are great for reheating leftovers, cooking frozen foods, or whipping up quick meals without turning on the oven.
By focusing on air fryer-friendly foods and following key tips, you can make the most of this amazing appliance—turning everyday ingredients into delicious, crispy, and healthy meals with ease. Happy cooking! 🍽️✨
