Tips from the EatingWell Test Kitchen

These are the key tips we learned while developing and testing this recipe in our Test Kitchen to make sure it works, tastes great and is good for you too! 

• Use an immersion blender to thoroughly beat the eggs and seasonings together and ensure a smooth mixture.
• Place the rimmed baking sheet near the oven (or on the oven rack) when you’re ready to pour the eggs into it. The shorter the distance you have to carry the unbaked quiche, the better.
• A well-greased baking sheet will work better than parchment paper here because some of the eggs will likely run underneath the paper.
• To avoid rubbery eggs, be careful not to overcook them. The eggs should just barely cook through to the center and no longer be wet when you take them out of the oven.

Nutrition Notes

• Eggs, like other animal-source foods, are high-quality complete proteins—giving you all nine essential amino acids. Egg yolks are also one of the best sources of an important nutrient called choline, which is important for brain health and in regulating mood and memory. 
• Hash brown potatoes can range in nutrition benefits, depending on the type or brand you choose. In general, frozen plain hash brown potatoes are shredded or cubed potatoes that have been partially cooked and frozen. You’ll still get a good amount of nutrients from the trusted potato, like potassium and B vitamins. Look for potatoes that still have the skin on for more fiber. 
• Cheddar cheese can range from mild to extra sharp, so use the type that you like. Cheddar is considered a hard cheese and, therefore, is lower in lactose, so it’s often tolerable for those who have a sensitivity to lactose-containing foods. It’s also a way to get more calcium into your diet, as hard cheeses, like Cheddar, are higher in calcium than soft cheeses. 
• As a member of the cruciferous vegetable club, broccoli is a nutritious addition to this recipe. It’s brimming with antioxidants that can help reduce inflammation, and adding broccoli easily increases the overall fiber content of a recipe.
