The BEST Dairy-Free Quiche {with Mushrooms + Leeks} (2024)

FAQs

What is the best milk substitute for quiche? ›

Oat Milk - I recommend using a creamy oat milk, like Oatly. The ones with oil do have the best creaminess, which will work well for the quiche texture. However, you can use any oat milk you like. Rice or hemp milk could also be substituted, but this may change the flavor.

"Some vegetables, such as sliced large tomatoes or raw zucchini, have a high water content and will make your quiche soggy (even if you follow all steps to avoid this!)," Davila notes. Instead, he recommends roasting vegetables such as mushrooms or eggplant before adding them to your egg mixture.

Heavy Cream and Milk – For the best tasting quiche, use a combination of whole milk and heavy cream. (Or simply use half-and-half.) Using just heavy cream produces an overly thick filling. Whole milk is great, but a combo of heavy cream and milk is better.

Too little dairy, and your quiche will be dry instead of creamy.

A nondairy milk (such as soy or almond) and a neutral oil (like vegetable or canola) can replicate heavy cream in certain recipes—namely, sauces and soups, but also some baked goods.

Among other milk alternatives like almond milk, soy milk and oat milk, soy milk is by far the best for baking. I learned this over the course of several years and many cookies, cakes, muffins and pies. Moreover, some people will tell you that you must swap full-fat coconut milk in for heavy cream or half-and-half.

Is quiche healthy? Quiche is bad news when it comes to a healthy diet. It's usually made with cheese and cream in the filling as well as butter in the pastry case, so it's often high in saturated fat and calories. Ingredients like bacon will add salt and more saturated fat.

Choose ingredients with lots of flavour and combine them with seasonal vegetables: onions, mushrooms, spinach and chard, leeks, candied or dried tomatoes... you have an infinite number of combinations that make quiche a pleasure that can be renewed without tiring.

Cook your veggies first

Kristin Beringson, the executive chef at Henley in Nashville, told Real Simple need to be pre-cooked before being added to your quiche. She said vegetables can take longer to cook than the egg custard, so pre-cooking them — whether sautéing or steaming — helps the whole dish cook evenly.

I love using yogurt because it gives it an extra bit of tang and some richness. I use Greek yogurt because regular yogurt has too much liquid. If you don't have yogurt, you can substitute it with a cup of cream or half-and-half.

Why is my quiche always watery? ›

If your quiche appears too watery to serve it could be because it was overbaked or underbaked, the egg to dairy ratio was not correct, the ingredients have too much liquid or it was baked on the wrong rack in the oven.

This is how to prep your quiche crust using the homemade or refrigerated option. And yes, as you'll see, you should always prebake quiche crust to avoid a gummy pastry.

The eggs need to be diluted with milk or cream, but if you use too much dairy, there will not be enough proteins from the eggs to set the quiche. The right ratio of milk to eggs allows the protein in the eggs to coagulate and set up a firm structure for the quiche.

Can you use milk in place of cream in quiches? Yes, while the fat in the cream helps the quiche set, if you've run out or forgot to pick some up from the shops, full-cream milk should work as a replacement most of the time. You could also try using buttermilk, crème fraîche or Greek-style yoghurt.

The healthiest milk alternative is soy milk because it's nutritionally comparable to dairy milk, says registered dietitian Jamie Nadeau. Dairy milk is an important source of protein, calcium, vitamin D and other nutrients. It contains 8 grams of protein per cup while soy milk contains just over 6 grams per cup.

You can put water in eggs instead of milk, however it may make your scrambled eggs too watery. If you aren't using milk, just use oil or butter. It will work just as well. Milk is not necessary when cooking eggs.

I love using yogurt because it gives it an extra bit of tang and some richness. I use Greek yogurt because regular yogurt has too much liquid. If you don't have yogurt, you can substitute it with a cup of cream or half-and-half.
