Use a sling to lower the dish onto the trivet in the pressure cooking pot. Lock lid in place and cook on High Pressure for 20 minutes. When the cook time ends, turn off the pressure cooker and let the pressure release naturally for 10 minutes, then finish with a quick pressure release.

When the valve drops, carefully remove the lid and use the sling to remove the dish from the pot. If you like broil the quiche in the oven until lightly browned.

Important Tips for Making Instant Pot Quiche

Since this is a crustless quiche, the texture and flavor of the egg mixture are very important. Don’t be afraid to season the eggs well with salt and pepper. And make sure you whisk the eggs and milk thoroughly before pouring the mixture over the vegetables, otherwise, your quiche may not bake evenly.

It’s also important to grease your baking dish or cake pan well before you add the vegetables. This ensures that the tomato quiche will be easy to remove and serve.

There are a few handy products to make this Instant Pot quiche. First, you’ll need a trivet. Most Instant Pot models come with one, but if yours didn’t, we love this trivet.

You’ll also need a 7-inch round cake pan. This pan from Fat Daddio’s fits into a 6-quart pressure cooker. You can also use a 1½-quart souffle dish. Just make sure it’s oven-safe!

To lower the quiche into the pressure cooking pot and remove it, you’ll need a sling. You can make your own sling out of aluminum foil. Or, invest in this great OXO reusable sling if you do a log of pot-in-pot cooking in the Instant Pot.

Frequently Asked Questions about Making Spinach Quiche

Can I make Instant Pot quiche ahead?

Yes! This is a great make-ahead dish. Simply wrap it tightly in plastic wrap or store in an airtight container, then keep in the fridge until ready to serve. You can serve the quiche cold or warm it in the Instant Pot to serve.

Can I freeze quiche?

Yes, freeze leftovers in an airtight container for up to six months. Defrost in the fridge overnight to serve.

Can I add other vegetables?

You can substitute the spinach in this recipe with another green, such as kale or chopped collard greens. Or, try sliced, sautéed mushrooms, diced sweet onions, or bell peppers instead of tomato.

Can I use a different kind of cheese?

Certainly! For the best results, use a shredded or crumbled cheese to replace parmesan. Cheddar, swiss, blue, or goat cheese would all work great.

I cooked it without foil covering the top. There was some liquid on top of the quiche after cooking, but I just use the corner of a paper towel to soak up the liquid. If you prefer to cook it with foil on top, you’ll need to add at least 5 minutes to the cook time and test for doneness.
