If you’re trying to eat healthier but still want convenience in the kitchen, you’ve probably wondered: Is an air fryer healthier than a microwave? Both appliances make cooking fast and easy, but when it comes to health, they work in very different ways.
Air fryers have taken over kitchens with their ability to make crispy, fried-like food with little to no oil. On the other hand, microwaves have been around for decades, known for quickly reheating meals and steaming food without added fat.
So, which one is the better choice for a healthy diet? The answer isn’t as simple as you might think. It depends on what you’re cooking, how you’re cooking it, and what you mean by “healthy.”
In this guide, we’ll break down how air fryers and microwaves work, compare their nutritional impact, and help you decide which one fits your lifestyle best.
How Air Fryers and Microwaves Work
Understanding how these two appliances work is key to figuring out which one is healthier. They use completely different cooking methods, which affect the texture, taste, and even the nutrients in your food.
What Is an Air Fryer?
An air fryer is like a compact convection oven. It circulates hot air around your food at high speed, creating a crispy, fried-like texture without submerging food in oil. Instead of deep frying, it uses just a light coating of oil (or none at all) to achieve that golden, crunchy finish.
How It Works:
- A heating element warms up the air inside the fryer.
- A powerful fan circulates the hot air rapidly, surrounding the food.
- The heat creates a crispy outer layer while cooking the inside evenly.
Air fryers are especially popular for foods like fries, chicken wings, and vegetables because they deliver a crunch without the extra grease. But they can also bake, roast, and even reheat leftovers.
What Is a Microwave?
A microwave is all about speed. It uses electromagnetic waves to heat water molecules inside the food, warming it from the inside out. This makes it great for reheating, steaming, and defrosting, but not for crisping or browning.
How It Works:
- Microwaves emit radiation that excites water molecules in food.
- The energy turns into heat, cooking food quickly and evenly.
- Because food retains moisture, it stays soft rather than crispy.
Microwaves are perfect for soups, pasta, rice, and leftovers, but they don’t create the crunchy texture that air fryers do.
Nutritional Impact: Air Fryer vs. Microwave
When it comes to healthy eating, it’s not just about how fast or easy an appliance is—it’s about how it affects the nutrients in your food. Both air fryers and microwaves have advantages and drawbacks in this area. Let’s take a closer look at how they compare.
Oil Usage and Fat Content
One of the biggest reasons people love air fryers is their ability to make crispy food with little to no oil. Traditional deep frying submerges food in oil, leading to high fat and calorie content. Air frying, on the other hand, uses rapid hot air circulation to mimic frying. You might still add a light spray of oil for texture, but it’s nothing compared to the amount used in deep frying.
Microwaves, however, don’t require oil at all. They work by heating the water molecules in food, meaning they won’t contribute to fat content. But unlike an air fryer, a microwave can’t crisp food—it simply heats it. That means if you’re cooking something like potatoes or chicken, you won’t get the crunchy exterior an air fryer provides.
So, which one is healthier? It depends on what you’re cooking. If you’re replacing deep-fried foods with air-fried versions, an air fryer is the healthier option. If you’re just reheating meals or steaming vegetables, a microwave is just as good—if not better—since it doesn’t require any oil.
Nutrient Retention in Food
Cooking methods affect how many nutrients stay in your food. High heat and long cooking times can break down vitamins and minerals, reducing their overall nutritional value.
Microwaves are actually one of the best cooking methods for preserving nutrients because they cook food quickly with minimal heat exposure. Studies show that microwaving vegetables helps retain more vitamins—especially water-soluble ones like vitamin C and B vitamins—compared to boiling or frying. Since microwaves heat food from the inside out, they don’t require added water that could leach nutrients away.
Air fryers, on the other hand, use higher temperatures and longer cooking times. While they don’t require water, the intense heat can still degrade some nutrients, especially in delicate vegetables. However, they don’t have the same nutrient loss as deep frying, making them a better alternative for fried foods.
If you’re steaming or reheating veggies, the microwave is the better option for nutrient retention. If you’re trying to reduce unhealthy fats in traditionally fried foods, the air fryer wins.
Which One Is Better for Nutrition?
It really depends on your cooking goals. If you’re aiming to cut down on oil and calories, an air fryer is a great choice. If you want to retain the most nutrients, especially in vegetables, the microwave is the better bet.
Both appliances have their place in a healthy kitchen, but understanding how they impact your food’s nutrition can help you make smarter choices. Next, let’s take a look at the potential health benefits and risks of each.

Health Benefits and Risks of Each Appliance
Both air fryers and microwaves offer health advantages, but they also come with some drawbacks. The real question isn’t just which one is healthier overall, but rather how each affects your food and your long-term well-being. Let’s break down the pros and cons of both.
Is an Air Fryer Healthier?
Air fryers have a strong reputation as a healthier alternative to deep frying. Since they use hot air instead of oil to cook food, they can significantly cut down on fat and calories. This makes them an excellent choice for people trying to reduce their intake of unhealthy fats without giving up crispy, flavorful foods.
One major health benefit of air frying is the reduction in harmful compounds like acrylamide. Acrylamide forms when starchy foods, such as potatoes, are cooked at high temperatures, like during deep frying. Studies suggest that consuming too much acrylamide may be linked to health risks, including cancer. Since air fryers use much less oil and cook at lower temperatures than deep frying, they produce less acrylamide, making them a healthier option.
However, air fryers are not perfect. While they reduce certain harmful compounds, they don’t eliminate them completely. Cooking meat at very high temperatures, such as in an air fryer, can still create polycyclic aromatic hydrocarbons (PAHs) and heterocyclic amines (HCAs)—compounds that have been linked to cancer in high amounts. This is similar to the risks of grilling or roasting at very high heat.
Another thing to consider is that air frying often makes food taste just as good as deep frying, which can encourage people to eat more processed, fried-style foods. While it’s healthier than deep frying, it doesn’t mean that eating air-fried foods every day is the best choice for an overall balanced diet.
Is a Microwave Healthier?
Microwaves have long been questioned for their safety and nutritional effects, but the reality is that they are one of the healthiest cooking methods available. Unlike frying or roasting, microwaving doesn’t require oil, which means it adds zero extra fat or calories to your meals.
One of the biggest health benefits of microwaving is its nutrient retention. Because microwaves cook food quickly and don’t require much added water, they help preserve more vitamins and minerals compared to boiling or frying. This makes them especially great for cooking vegetables, as they retain more of their antioxidants and water-soluble vitamins like vitamin C and B vitamins.
Microwaves are also one of the safest cooking methods when it comes to harmful compounds. Since they don’t use extreme heat or prolonged cooking times, they don’t produce acrylamides, PAHs, or HCAs. This makes them a great choice for people who want to reduce their exposure to these potentially harmful chemicals.
That being said, microwaves do have a few downsides. Because they heat food by exciting water molecules, they can sometimes dry out food unevenly or create hot spots. This is especially true for meats, where the uneven heating might not always kill bacteria effectively unless cooked properly.
There’s also a long-standing myth that microwaves destroy nutrients or make food radioactive. This is false—microwaves simply heat food by causing molecules to vibrate, and they don’t change the chemical structure of the food itself. In fact, because they use less heat than other cooking methods, they actually preserve more nutrients than boiling or frying.
Which One Is the Better Choice?
It depends on what you’re cooking and how often you use each appliance. If you want to avoid extra fat and harmful frying compounds, an air fryer is a great alternative to deep frying. If you’re focused on preserving nutrients and cooking without added fats, a microwave is the healthier option.
Both appliances can be used in a balanced diet, and the best approach might be to use them together—air fry for crispy textures and microwave for quick, nutrient-rich meals. Up next, let’s compare how they handle different types of foods and which one is better for various cooking needs.
Cooking Versatility and Food Quality
When choosing between an air fryer and a microwave, it’s not just about health—it’s also about how well they cook different types of food. Some meals turn out crispy and delicious in an air fryer, while others are better suited for the quick, even heating of a microwave. Let’s break it down.
What Foods Work Best in an Air Fryer?
Air fryers shine when it comes to foods that benefit from a crispy, golden-brown texture. If you love fried foods but want a healthier alternative, an air fryer can give you that crunch without the excess oil.
One of the best things to cook in an air fryer is frozen foods like French fries, chicken nuggets, and mozzarella sticks. These come out crispy and evenly cooked without needing deep frying. The hot air circulation helps them develop a crunchy outer layer while keeping the inside tender.
Air fryers are also great for roasting vegetables. Unlike steaming or boiling, which can make veggies mushy, air frying caramelizes the edges and enhances their natural sweetness. Broccoli, Brussels sprouts, carrots, and even zucchini can turn into crispy, flavorful sides with just a light drizzle of oil.
Another food category that works well is proteins like chicken, fish, and tofu. An air fryer can give chicken a crispy skin without needing batter or excess oil, and it’s a great way to cook salmon or shrimp without drying them out. It also works well for plant-based proteins like tofu, creating a crispy outside while keeping the inside soft.
Baked goods like cookies, muffins, and even small cakes can also be made in an air fryer. The circulating heat ensures even baking, often in less time than a regular oven. Some people even use air fryers to “revive” leftover pizza, bringing back the crispiness that a microwave can’t achieve.
However, air fryers aren’t perfect for everything. Foods with a lot of liquid, like soups or stews, won’t work. Soft foods that need gentle heating, like sauces or delicate desserts, can also dry out or burn easily.
What Foods Work Best in a Microwave?
Microwaves are unbeatable when it comes to quick, convenient cooking. They excel at heating foods evenly and preserving moisture, which makes them ideal for certain dishes.
One of the best uses for a microwave is reheating leftovers. Unlike an air fryer, which can sometimes overcook food when reheating, a microwave gently warms up dishes like pasta, rice, and casseroles while keeping them moist. It’s also the best way to heat up soups, stews, and sauces without altering their texture.
Microwaves are also excellent for steaming vegetables. While air fryers create a crispy finish, microwaves help retain moisture and preserve nutrients. A quick steam in the microwave can leave broccoli, spinach, and green beans vibrant and tender without overcooking them. Plus, there’s no need for added oil, making it a great option for those focused on pure, natural flavors.
Another area where microwaves shine is cooking grains like rice, quinoa, and oatmeal. Instead of waiting for water to boil on the stovetop, a microwave can cook grains quickly and evenly. Some people even use it to prepare baked potatoes or sweet potatoes in a fraction of the time it would take in an oven or air fryer.
Microwaves are also the best choice for defrosting. Whether you’re thawing frozen meat, bread, or even frozen fruit for smoothies, a microwave’s defrost setting is much faster than waiting for food to thaw at room temperature.
However, the downside is that microwaved food lacks the crispy or caramelized textures that other cooking methods can achieve. While it’s great for steaming and heating, it won’t give you the golden-brown finish that an air fryer provides.
Which Appliance Wins for Cooking Versatility?
It depends on what you’re making. If you want crispy, roasted, or air-fried foods, an air fryer is the way to go. If you need to quickly heat, steam, or cook softer foods, a microwave is the better choice. Many home cooks find that using both appliances together gives them the best of both worlds—crispy textures from the air fryer and fast, even heating from the microwave.
Which Appliance Should You Choose for a Healthier Diet?
When it comes to making healthier meals, both air fryers and microwaves have their advantages. The best choice depends on your cooking habits, the types of foods you eat, and what “healthy” means to you. Let’s break it down.
If you’re trying to cut back on unhealthy fats while still enjoying crispy, flavorful foods, an air fryer is the better option. It allows you to cook traditionally fried foods with little to no oil, reducing calorie intake without sacrificing texture. It’s a great choice for anyone who loves crispy vegetables, lean proteins, or air-fried versions of their favorite comfort foods.
On the other hand, if your priority is nutrient retention, especially when cooking vegetables and whole grains, a microwave is the healthier choice. Microwaves cook food quickly without high heat exposure, helping to preserve vitamins and minerals. Plus, since they don’t require any oil, they’re great for preparing meals with minimal added fat.
For most people, the ideal approach is to use both appliances in a balanced way. An air fryer is excellent for crisping, roasting, and reducing oil consumption, while a microwave is unbeatable for quick steaming, reheating, and nutrient-rich cooking.
At the end of the day, healthy eating isn’t just about the appliance—it’s about what you put in it. Whether you choose an air fryer or a microwave, focusing on whole, minimally processed foods and balanced meals will have the biggest impact on your health.
