Deviled eggs are one of my favourite appetizers. They are easy to make, and usually gluten-free. Some mayonnaise uses malt vinegar (barley), so just check the ingredients.
Start by boiling eggs. They need to be hard boiled, so the yolk makes a nice firm filling. Use your favourite way to boil eggs: in a pot of water, using a instant pot or an egg boiler. Then cool the eggs in an ice bath (ice cubes and cold water in a bowl), peel and cut in half length wise. Gently scoop out the yolks into a bowl.

Use the one that you are comfortable with. You just need to boil eggs.
The DASH Rapid Egg Cooker is easy to use. Just fill the small plastic measuring cup to the hard boil line and pour the water on to the heating plate. Add the number of eggs you want to cook into the boiling tray, don't forget to use the small metal needle in the bottom of the measuring cup to poke a hole in each egg. This is so the eggs don't explode. Cover and press the start button on the front and wait till the timer goes off. Turn off and unplug and voila boiled eggs!
Follow your Instant Pot instructions. My 6 quart instructions for 8-12 eggs: Add eggs and 1 1/2 cups (375 mL). Cook pressure level on High for about 3 to 5 minutes and use natural release venting method.
Using a pot. I put the eggs in a single layer in the pot, and cover with cold salted water. Bring water to a boil, and then lower to a simmer and cook covered for about 5 minutes. Some recipes call for putting the eggs in cold water and bringing to a rapid boil, then turning off the heat, put on the lid, and leave the eggs in the hot water for about 12 minutes. Which method do you use?
For the oven method: Preheat oven to 325 Fahrenheit. Put eggs into a muffin tin. This prevents them from rolling around. Bake for about 30 minutes for hard boiled.
Air Fryer method: Preheat your air fryer to 250 Fahreheit. Put the eggs into the air fryer basket. Cook for about 15 minutes for hard boiled.
For all methods of cooking, after the eggs are done plunge them into a water/ice bath for about 10 minutes. This will make the eggs easier to peel.

I make a basic deviled egg filling: egg yolks, mayonnaise, mustard, salt and pepper. Mash the egg yolks first and then add the rest of your ingredients.

Sometimes I like to add a little relish.

Mix the filling ingredients until combined and then fill the egg whites. You can use a small spoon or put the filling in a piping bag. I usually just use a spoon.

I use a small spoon to put the filling into the egg whites. If you want to make the eggs fancy, you can put the filling in a piping bag, and pipe the filling in. Sprinkle with paprika.
