Air Fryer Cottage Pie

A comforting twist on a British classic, this Air Fryer Cottage Pie brings all the rich, hearty flavours of a traditional cottage pie with the added convenience and crisp finish that only an air fryer can deliver. Succulent minced beef cooked slowly with soft carrots, peas, a rich gravy seasoned with tomato and herbs, and finished with creamy mashed potato and a golden cheesy top — it’s the ultimate midweek family dinner.

The beef filling is gently simmered on the hob to develop deep flavour and tender vegetables, then layered with fluffy mash and air-fried until the mature Cheddar on top is perfectly golden and bubbling. 

This recipe is designed to make the most of the air fryer’s abilities: saving energy and time while giving you less washing up and an irresistibly crisp topping that sets it apart from oven-baked versions. It’s wholesome, satisfying, and ideal for feeding a hungry family on a busy evening.

Serve it straight from the air fryer with extra vegetables or bread and butter on the side if you want to make it go further — but it’s perfectly complete on its own with meat, veg, gravy and mash in one delicious dish.

When I first bought an air-fryer, and started writing recipes for it (absolutely jumping on what was at the time a profitable bandwagon!) I really wanted to do all elements of a recipe in the air fryer. 

I thought this was the only way to really make it worth it in terms of saving time and cutting energy use. 

This worked for some things. Mac and cheese is great, toasties are perfect, cottage pie, not so much. 

To be really great, a cottage pie filling needs a nice slow simmer. Without this, you’ll have a watery gravy, firm carrots, and you’ll lose that lovely, thick, rich gravy. It’s just not worth it, and it’s not something that the air fryer does well. 

To me, this felt a bit like a failure.

But, over time, I’ve embraced more flexibility with the air fryer. I’ve realised that many people are without an oven (by choice, or circumstance), but still have access to a hob and an air fryer. For them, being able to finish the dish in the air fryer instead of the oven is all that they need. 

Using the air fryer instead of the oven for baking still saves time and energy, while ensuring that the top is lovely and crispy, playing to the air fryer’s strengths without ruining the recipe. 

Ingredients, Variations and Substitutions

Olive Oil

Onion 

Garlic Puree – You can swap for fresh garlic cloves, but I love a puree!

Minced Beef – Swap to lamb mince if you prefer a shepherd’s pie, or use chunks of beef or lamb instead of mince. See my leftover roast beef cottage pie for tips.

Carrots 

Frozen Peas

Beef Stock

Tomato Puree

Henderson’s Relish – Other, similar relishes are also available. 

Mixed Herbs 

Salt and Pepper

Beef Gravy Granules – You can skip this, but it will take longer for your sauce to thicken, and I think it loses some of the lovely, rich, beefy flavours. 

White Potatoes – Something like Maris Piper or King Edwards that mash well. 

Butter – Or margarine.

Milk – I use semi-skimmed.

Salt and Pepper

Mature Cheddar Cheese 

You’ll Also Need

To make an air fryer cottage pie, you need a chopping board and a sharp knife to prepare your ingredients. 

Then you need a large, non-stick, flameproof pan and a spatula to cook the filling, and a potato peeler, a saucepan and a colander for the mash. 

You’ll also need a grater for the cheesy top. 

Then, to bake your cottage pie, you’ll need an air fryer and an appropriate dish. 

I use these silicon baskets (Affiliate Link), which I absolutely love. Silicon means that they are easy to clean, and these particular ones are deep enough for full meals.

They also have firm bottoms and long handles, so your meals hold their shape when you lift them out of the air fryer basket. 

I also recommend a food thermometer when cooking in an air fryer, to make sure the middle is at a safe temperature.

I use one like this (affiliate link).

How to Air Fry Cottage Pie – Step-by-Step Instructions

Full, easy-to-follow instructions and quantities are available in the recipe card at the bottom of this post.

Step One

Warm a splash of olive oil over medium heat on the hob.

I use a large frying pan, but any flameproof dish or pan is fine.

Step Two

Add the onions and fry for 10 minutes, stirring often. You want them really soft, so don’t be tempted to rush this bit. 

Step Three

Stir through the garlic puree.

If you use puree, you can stir it in and move on to the next step. If you are using fresh garlic, cook it for a few minutes, stirring often, before adding the mince. 

Step Four

Add the mince and break it apart using your spatula or a fork. I use my spatula. 

Step Five 

Fry for 5 minutes until browned, stirring often.

This might take a little longer, depending on how big your pan is and how thin the layer of beef is. Just make sure it’s nice and brown. 

Step Six

Stir in the carrots.

You’ll notice there are already peas in my photo. I was very guilty of a very soft pea.

Step Seven

Pour in the stock and Henderson’s Relish, and add the tomato puree, mixed herbs, salt, pepper and gravy. 

Step Eight

Stir well. 

Step Nine

Bring to a simmer and reduce the temperature if necessary. You want a nice, steady simmer, not a violent bubble. 

Step Ten 

Simmer for around 45 minutes, stirring often until the gravy is thick and the carrots are soft. Add the peas for the last 5-10 minutes.

Again, this might take longer or less, depending on the pan. 

Step Eleven

While your filling is cooking, prepare your mash. You can do this your own way if you prefer. This is just how I make mash. 

Step Twelve

Peel and dice the potatoes. They should be in 2cm chunks. 

Step Thirteen

Add to a pan of boiling water and cook for 20 minutes, carefully skimming off any foam that rises to the top with a spoon. 

Step Fourteen

Drain well, and return to the saucepan. 

Step Fifteen

Place over a very low heat and shake to toss for 1-2 minutes to remove excess water.

I actually turn the heat off and toss them on the still-warm hob; it’s enough. 

Step Sixteen

Remove from the heat. 

Step Seventeen

Add the milk, butter, and a pinch of salt and pepper.

You can skip the salt and pepper, but I love that bit of flavour. 

Step Eighteen 

Mash until smooth. Add a splash more milk or a little more butter if needed. 

Step Nineteen – How Long to Cook Cottage Pie in an Air Fryer

Preheat the air fryer to 180 Degrees C and set for 10 minutes.

Step Twenty – Back to the Filling

When the mixture is done, remove it from the heat and carefully spoon it into a silicon air fryer basket or a casserole dish that fits and is appropriate for your air fryer. 

I use a basket with long handles that’s easy to get in and out of. It’s also reasonably deep for a nice big pie.

What you use will depend on your air fryer’s size, but I recommend something deep for this particular recipe. It’s a thick layer of mash!

Step Twenty-One

Spoon on the mashed potato and spread evenly. If you want, you can pipe it on nice and neat, but I spoon it on. 

Step Twenty-Two

Sprinkle over the grated cheese. I use quite a bit.

You can use less if you want, just a nice layer on top. 

Step Twenty-Three

Add to the preheated air fryer drawer and air fry for 10 minutes until the cheese is golden brown.

Everything is cooked and warm, so you just need to brown the top. You can air fry for a little longer if needed.
