The Best Fluffy Pancakes recipe you will fall in love with. Full of tips and tricks to help you make the best pancakes.

If you’re looking for a simple, comforting meal that comes together with minimal fuss, the Impossible Quiche might be your new favorite recipe. This crustless quiche became popular in the 1970s thanks to Bisquick, a baking mix that helped home cooks whip up pies and casseroles quickly. The name “Impossible” comes from the seemingly magical way it forms its own crust while baking—no rolling pin required!
Whether you’re serving brunch, lunch, or a light dinner, this quiche is a versatile, crowd-pleasing dish. Let’s dive into what makes it so special and how you can make it at home.
🥚 What Is an Impossible Quiche?

An Impossible Quiche is essentially a crustless quiche that forms its own base while baking. The secret is in the batter: a mixture of eggs, milk, and Bisquick (or another all-purpose baking mix) that settles during baking to create a light, slightly crispy layer on the bottom—almost like a crust.
This dish is perfect for anyone who wants the flavor of a quiche without the hassle of making a pastry crust. It’s also incredibly customizable, making it a great way to use up leftovers or get creative with your favorite ingredients.
🧀 Classic Impossible Quiche Recipe
Ingredients
- 4 large eggs
- 1 cup milk (whole or 2% recommended)
- ½ cup Bisquick baking mix
- 1 cup shredded cheese (cheddar, Swiss, or a mix)
- ½ cup chopped onion
- ½ cup cooked bacon or diced ham
- ¼ tsp salt
- ¼ tsp ground black pepper
Optional Add-Ins
- Chopped spinach or kale
- Diced bell peppers or mushrooms
- Fresh herbs like parsley or chives
Instructions
- Preheat the oven to 400°F (200°C). Grease a 9-inch pie dish or baking pan.
- Layer the fillings: Spread the meat, cheese, and vegetables evenly in the bottom of the dish.
- Make the batter: In a mixing bowl, whisk together the eggs, milk, Bisquick, salt, and pepper until smooth.
- Pour the batter over the fillings in the pie dish.
- Bake for 30–35 minutes, or until the top is golden and a knife inserted in the center comes out clean.
- Cool slightly before slicing and serving. It’s delicious warm or at room temperature.
🧑🍳 Tips for Success
- Don’t overmix the batter—it should be smooth, but overmixing can make the quiche tough.
- Use room-temperature ingredients for better texture and even baking.
- Let it rest for 5–10 minutes after baking to make slicing easier and improve flavor.
- Make it ahead: This quiche stores well in the fridge for up to 3 days and reheats beautifully.
