Can a Casserole Be Cooked in an Air Fryer? The Surprising Truth

Let’s be honest—casseroles are the ultimate comfort food. They’re hearty, filling, and perfect for busy weeknights or feeding a crowd. But if you’ve ever stood over a hot oven for an hour waiting for your cheesy, bubbly casserole to finish, you’ve probably asked yourself: Is there a faster way? Enter the air fryer, the kitchen gadget that’s revolutionized how we cook. It’s fast, energy-efficient, and great for crisping up leftovers. But can it handle a full casserole? The answer might surprise you.

When I first got my air fryer, I was skeptical. Could a countertop appliance really replace my trusty oven for dishes like lasagna, mac and cheese, or chicken pot pie? I decided to test it out—with mixed but ultimately promising results. In this post, I’ll walk you through everything you need to know about cooking a casserole in an air fryer. From what works (and what doesn’t) to practical tips and real-life examples, you’ll learn how to save time, reduce cleanup, and still enjoy that classic casserole comfort—without the oven heat. So, can a casserole be cooked in an air fryer? Let’s find out.

Understanding How Air Fryers Work (And Why It Matters)

Air Fryer Basics: Convection Cooking in a Compact Package

Before we dive into casserole recipes, it helps to understand how air fryers actually work. Unlike traditional ovens, which heat the air slowly and rely on radiant heat, air fryers use a powerful fan to circulate hot air around your food. This is called convection cooking, and it’s what gives air-fried foods that crispy, golden exterior in a fraction of the time.

Think of it like a mini convection oven. The rapid air movement cooks food more evenly and quickly, especially on the outside. That’s why frozen fries come out crispy in 15 minutes instead of 25 in the oven. But here’s the catch: casseroles are dense, layered, and often contain ingredients that need to cook slowly from the inside out. So while the outside might get crispy fast, the center can stay undercooked if you’re not careful.

The Size and Shape Challenge

Another key factor is the size and shape of your air fryer basket. Most air fryers range from 3.5 to 6 quarts, which limits how much food you can cook at once. A standard 9×13-inch casserole dish is way too big. But that doesn’t mean you’re out of luck. You’ll need to adapt by using smaller, oven-safe cookware that fits inside the basket—like mini loaf pans, silicone molds, or small metal or glass dishes (usually 6 to 8 inches).

Here’s a tip: Always check your air fryer’s manual for recommended cookware dimensions. Some models come with a crisper tray or a rack, which can help elevate your dish and improve airflow. The goal is to let hot air reach all sides of your casserole—not just the top.

Temperature and Time Adjustments

Because air fryers cook faster, you’ll need to adjust both temperature and time. A good rule of thumb is to reduce the oven temperature by 25°F (about 15°C) and shorten the cooking time by 20-30%. For example, if a casserole normally bakes at 375°F for 40 minutes, try 350°F for 25-30 minutes in the air fryer. But—and this is important—always check for doneness using a meat thermometer (165°F for poultry) or a knife test (pasta should be tender, cheese bubbly).

Pro tip: Start checking at the lower end of the time range. It’s easier to add more time than to fix overcooked, dry food.

Which Casseroles Work Best in an Air Fryer?

Top 3 Casserole Types That Shine

Not all casseroles are created equal when it comes to air frying. Some adapt beautifully, while others fall flat. Based on my testing (and a few kitchen disasters), here are the casserole types that work best:

• Small-batch pasta casseroles (like mini lasagna or baked ziti)
• Cheesy potato or hash brown casseroles (think tater tot casserole)
• Layered egg or breakfast casseroles (savory strata or frittata-style)

Why do these work so well? They’re usually smaller in volume, have ingredients that crisp nicely, and benefit from the air fryer’s ability to brown the top without drying out the center. For example, I made a mini tater tot casserole last weekend using a 6-inch cast-iron pan. The tater tots got perfectly crunchy, the cheese melted into a gooey layer, and the whole thing was ready in 22 minutes—about half the time of the oven version.

Casseroles to Approach with Caution

Now, let’s talk about the ones that can work—but require extra care:

• Large, dense casseroles (like a 9-inch deep-dish lasagna)
• Casseroles with raw meat on the bottom layer (chicken and rice, for example)
• Very liquid-heavy dishes (like soupy casseroles or those with lots of sauce)

These are tricky because the air fryer’s intense heat can dry out the top or undercook the bottom. But with a few tricks (like covering with foil or using a water bath), you can still make them work. For instance, I once made a chicken and broccoli casserole by pre-cooking the chicken and rice, then layering everything in a small dish and air frying at 325°F for 20 minutes. I covered it with foil for the first 15 minutes to trap steam, then removed it to crisp the top. It turned out great—juicy, not dry, and fully cooked.

What About Dessert Casseroles?

Yes, even desserts can be air-fried! Think apple crisp, bread pudding, or mini peach cobbler. The key is to use a dish with low sides so the fruit or filling doesn’t bubble over. I tried a mini apple crisp in a 5-inch pie tin, and it was ready in 18 minutes. The oat topping got golden and crunchy, while the apples stayed tender. Just be sure to place a foil-lined tray underneath to catch any drips—air fryer baskets aren’t fans of sticky messes.

Step-by-Step Guide: How to Cook a Casserole in an Air Fryer

Step 1: Choose the Right Dish

Your casserole’s success starts with the right cookware. Look for oven-safe dishes that fit snugly in your air fryer basket. I use:

• 6-inch cast-iron skillet (great for heat retention)
• Silicone loaf pan (flexible, easy to remove)
• Small metal or glass casserole dish (check height—should be under 3 inches)

Never use non-stick or plastic dishes that aren’t rated for high heat. And avoid dishes with handles that stick out—they can block airflow or damage the basket.

Step 2: Prep Your Ingredients

Since air frying is faster, you’ll need to adjust your prep:

• Cook raw meat, pasta, or rice beforehand unless your recipe is designed for slow cooking (like a casserole that simmers in sauce).
• Drain excess liquid from canned veggies or sauces to prevent soggy layers.
• Layer ingredients thoughtfully—denser items (meat, potatoes) go on the bottom, lighter items (cheese, breadcrumbs) on top.

For example, in my mini chicken and broccoli casserole, I pre-cooked the chicken, boiled the broccoli for 2 minutes, and used pre-cooked rice. This ensured everything cooked evenly in the air fryer.

Step 3: Assemble and Add a Crisping Topping

Once your ingredients are ready, layer them in the dish. Then, add a crisping agent to mimic the oven’s browning effect:

• Cheese (cheddar, mozzarella, Parmesan)
• Breadcrumbs or panko (toss with oil or melted butter)
• Crushed crackers or potato chips

I like to mix ½ cup panko with 1 tbsp melted butter and a sprinkle of garlic powder. It gives a golden, crunchy crust in just a few minutes.

Step 4: Air Fry with Foil (Optional)

This is my secret weapon. Cover the casserole with foil for the first 10-15 minutes to trap steam and prevent the top from burning. Then, remove the foil and air fry for another 5-10 minutes to crisp the top.

For example, my mac and cheese casserole (made with 1 cup cooked pasta, ½ cup cheese sauce, and ¼ cup shredded cheese on top) went into the air fryer at 350°F. Foil on for 12 minutes, then foil off for 5 minutes. The result? Creamy inside, crispy on top—perfect.

Step 5: Check for Doneness

Use a meat thermometer (165°F for chicken) or insert a knife into the center. If it comes out hot and the pasta/veggies are tender, you’re good. If it’s still cold, add 3-5 minutes and check again.

Pro tip: Let the casserole rest for 2-3 minutes after cooking. This helps the layers settle and prevents a messy spill when you serve it.

Common Mistakes (And How to Avoid Them)

Overfilling the Basket

One of the biggest mistakes? Piling too much food into the dish. Air fryers need space for hot air to circulate. If your casserole fills the dish to the brim, the center won’t cook properly. Fill your dish no more than ¾ full, and leave at least 1 inch of space below the basket’s top.

When I first tried a lasagna, I used a 7-inch dish and filled it to the top. The edges were dry, but the middle was still cold. Lesson learned: smaller portions work better.

Skipping the Foil

Air fryers can dry out food fast. If you don’t cover the casserole initially, the top might burn before the bottom is done. Foil is your friend—especially for casseroles with cheese or breadcrumbs.

But don’t leave it on too long. Once the center is warm, remove the foil to crisp the top. I’ve seen people leave foil on the whole time and end up with a soggy, pale casserole. Not ideal.

Using the Wrong Temperature

Air fryers vary in power. A 1500-watt model will cook faster than a 1200-watt one. Start with the lower end of the temperature range (325-350°F) for dense casseroles, and increase only if needed. High heat (400°F+) is better for crisping, not slow cooking.

I once tried cooking a potato casserole at 375°F from the start. The potatoes on top burned, while the ones underneath were raw. Now I use 325°F for the first 15 minutes, then 350°F to finish.

Ignoring the Water Bath Trick

For extra insurance against drying out, try a water bath. Place your casserole dish inside a larger, shallow pan (like a cake pan) and add 1-2 cups of hot water around it. The steam keeps the casserole moist while the top crisps.

I used this for a quiche-style casserole, and it came out perfectly creamy—no rubbery texture. Just be careful not to let water splash into the dish.
